Cisco has disabled public access to one of its DevHub environments after threat actors downloaded some customer data from the site and put it up for sale on a cybercrime forum.

The compromised data included source code, API tokens, hardcoded credentials, certificates, and other secrets belonging to some large companies, including Microsoft, Verizon, T-Mobile, AT&T, Barclays, and SAP.

**Data Heist From Public-Facing Environment**

News of the breach first surfaced a week ago, when researchers spotted three threat actors using the monikers IntelBroker, EnergyWeaponUser, and zjj, putting up the data for sale on BreachForums. IntelBroker is a known Serbian entity that began operations in 2022 and is linked to several major data heists, including ones at Europol, General Electric, and DARPA (Defense Advanced Research Projects Agency).

Cisco announced it was investigating the incident on Oct. 15. Three days later, the company confirmed the security incident in an update that offered little detail on the kind of data that the attackers managed to access and download.

Cisco's own systems appear not to have been affected in the incident. "We have determined that the data in question is on a public-facing DevHub environment — a Cisco resource center that enables us to support our community by making available software code, scripts, etc. for customers to use as needed," Cisco's advisory noted. "At this stage in our investigation, we have determined that a small number of files that were not authorized for public download may have been published."

The company said that, at the moment, there is no evidence the attackers illegally accessed any personal identity data or financial information, but it added that it was still investigating that possibility. "Out of an abundance of caution, we have disabled public access to the site while we continue the investigation," the company said.

In their BreachForums post, the threat actors claimed the data they downloaded from Cisco's DevHub site included GitHub and GitLab projects, source code, Jira tickets, container images, data from AWS storage buckets, and at least some confidential Cisco information.

**Reminder: The Need to Secure Public-Facing Assets**

The Cisco incident is a reminder why organizations need to protect public-facing environments with measures like input validation to protect against injection attacks, strong authentication tools and processes, and regular vulnerability assessments, says Jason Soroko, senior fellow at Sectigo.

Common mistakes organizations make when it comes to securing their public-facing assets include neglecting OWASP guidelines, underestimating security risks, failing to update systems regularly, and not prioritizing secure coding practices, Soroko says: "Don't forget to back up your website code and practice restoring it. Malware detection tools are available that make it easy to regularly scan."

Organizations can sometimes tend to perceive their public-facing assets as less critical when, in reality, they can expose sensitive information that attackers could use for future intrusions, he adds. The data that the attackers obtained in the Cisco incident, for instance, included source code, API tokens, certificates, and credentials that attackers could potentially leverage in a significant way in a future campaign.

Eric Schwake, director of cybersecurity strategy at Salt Security, says various factors contribute to sensitive data ending up on an organization's public-facing environments. "This can occur due to accidental misconfigurations of access controls, human errors in code or file management, inadequate security testing before deployment, or the compromise of third-party services," he says. These oversights can lead to the exposure of sensitive data and create potential entry points for attackers.

Schwake recommends that organizations implement a multilayered security strategy to reduce this risk. "This involves enforcing strict access controls, promoting secure coding practices, conducting thorough security testing, building posture governance standards, and performing regular security assessments," he says. "Using secrets management solutions and continuous monitoring tools can further improve security and protect against unauthorized access to sensitive information."

Cisco Disables DevHub Access After Security Breach

This latest breach was through Zendesk, a customer service platform that the organization uses.

Just a few days after the Internet Archive told the public it was getting back on its feet after a data breach and a barrage of distributed denial-of-service (DDoS) attacks forced it to go offline, the digital library website is once again in trouble.

Unknown bad actors have allegedly claimed access tokens to the archive's Zendesk implementation, using them to send a mass email on Oct. 20 to those who tried to interact with the archive's platform.

The email began as follows:

"It's dispiriting to see that even after being made aware of the breach two weeks ago, IA has still not done the due diligence of rotating many of the API keys that were exposed in their GitLab secrets," the hacker stated. “As demonstrated by this message, this includes a Zendesk token with perm\[ission\]s to access 800K+ support tickets sent to \[email protected\] since 2018." 

The email continued, "Whether you were trying to ask a general question or requesting the removal of your site from the Wayback Machine — your data is now in the hands of some random guy. If not me, it'd be someone else."

Though it can’t be said for certain, Chris Hickman, chief security officer (CSO) of Keyfactor, said the hacker may not have serious malicious intent, but instead wants to prove a point: that those in charge of the Internet Archive must be more proactive in protecting its network from those who would do much worse.

"This is a security oversight as tokens that are not rotated regularly have longer lifespans, increasing the window of opportunity for attackers to steal and misuse them," Hickman wrote in an emailed statement to Dark Reading. "If a token is not rotated correctly, it might expire, leading to authentication failures for legitimate users. If a malicious actor obtains an unrotated token, they could use it to gain unauthorized access to systems or services, leading to service disruptions and customer frustration, damaging a company's reputation and bottom line."

The organization hasn't made any public comments regarding the latest breach, but it did request donations last week to help support its endeavors of promoting open access to knowledge resources.

Internet Archive Gets Pummeled in Round 2 Breach

The emergence of novel anti-detection kits for sale on the Dark Web limit the effectiveness of a Chrome browser feature that warns users that they have reached a phishing page.

Cybercriminals have found a new way to get around what has been an effective deterrent to phishing attacks, with novel anti-bot services sold on the Dark Web that allow them to bypass the protective "Red Page" warning in Google Chrome that alerts users to potential fraud.

The anti-bot services aim to prevent security crawlers from identifying phishing pages and blocklisting them by filtering out cybersecurity bots and disguising phishing pages from Google scanners, according to new research published today by SlashNext.

They do this by rendering ineffective the Red Page, a feature of Google Safe Browsing — which itself is a feature of Chromium-based browsers and other Google services — that aims to protect users from harmful websites by warning them of potential dangers, such as phishing attempts. The page is so-named because it is displayed in red and provides a warning that a site to which someone is navigating may be deceptive, advising them to avoid it.

In doing so, the warning can "severely" limit "the potential success of phishing attacks," according to the post, providing "a massive hurdle" to threat campaigns. That's because these campaigns rely on high click-through rates, which is significantly lowered when Google's detection flags a phishing page and adds it to a blocklist.

Now various anti-bot services found on the Dark Web, such as Otus Anti-Bot, Remove Red, and Limitless Anti-Bot, "threaten to undermine this line of defense, potentially exposing more users to sophisticated phishing attempts," according to the post.

**How Anti-Bot Services Work**

Though each service has its own unique features, they are all based on a combination of several techniques that allow malicious content to bypass Google's Red Page feature. Most rely on bot detection mechanisms that analyze user-agent strings and IP addresses to filter known security bot traffic that would otherwise be blocked, according to SlashNext.

"Public lists of cybersecurity crawlers are widely available (for example, Shodan), making it easy to filter known security bot traffic," according to the post. "Once an IP address or user-agent is flagged as a security crawler, it is blocked, ensuring the page remains accessible to real users but hidden from cybersecurity entities."

The services also use cloaking techniques such as context-switching or JavaScript obfuscation to serve different content based on the visitor’s profile. These techniques effectively redirect security crawlers to benign content while directing a user to a phishing page.

Another common feature of the anti-bot services is to introduce CAPTCHA or challenge pages to filter out automated scanners that typically would analyze a webpage for malicious content. "Since most bots cannot solve CAPTCHAs, this technique effectively blocks them while allowing real users through," according to the post.

Some anti-bot services might even introduce a time delay, which further confuses security bots by making them "time out" before they can scan the page and thus warn users of a potential security threat.

They also can bypass the Google Red Page by delivering region-specific content and blocking foreign traffic, according to SlashNext. For example, if a phishing campaign is targeting a Korean bank, the service might allow only Korean traffic to visit the site while blocking foreign IP addresses, the researchers noted. Moreover, these methods can get extremely specific in terms of geography, even narrowing campaigns down to the city level, which would prevent international cybersecurity services from detecting the page entirely, according to the post.

**Not Completely Foolproof**

While these anti-bot services can significantly reduce the scope of Google Red Page, they do have their limitations, the researchers noted. The malicious services work best in less sophisticated phishing campaigns because they can identify and block known crawlers in the user-agent string — where many security vendors declare their bots and crawlers, the researchers noted.

"This allows cybercriminals to filter out bot traffic, prolonging the lifespan of phishing campaigns," according to the post. However, in more sophisticated phishing operations, manual analysis by analysts will eventually detect the page, leading to its inclusion on blocklists.

Still, anything that can limit the detection of phishing by end users is a threat to the overall security, not just of individuals but also enterprises. That's because despite being one of the oldest forms of cybercrime, phishing is still one of the primary ways attackers gain initial entry onto corporate networks to perform other types of malicious activities, such as ransomware attacks.

Moreover, the rise in the availability of phishing kits that make it easy for attackers to create campaigns, the growing sophistication of phishing tactics and now the emergence of anti-bot services make detection by individuals and defenders more complex.

The best defense against the use of anti-bot services to bypass Google Red Page is to use security platforms that can detect threats in real-time across email, mobile, and messaging apps with as much accuracy as possible, according to SlashNext. Aforementioned manual analysis of phishing pages and the subsequent addition of malicious sites to blocklists also can prevent these services from being effective.

Anti-Bot Services Help Cybercrooks Bypass Google 'Red Page'

The future of application security is no longer about reacting to the inevitable — it's about anticipating and preventing attacks before they can cause damage.

COMMENTARY

In my years managing security in complex environments, I've seen how threats and defenses evolve, but application security has proven a very tough nut to crack. What excites me today is the significant progress we're making in closing long-standing gaps in AppSec, and I would argue that application detection and response (ADR) is leading the charge. 

**A Fresh Take on an old Problem**

Historically, application security has been reactive. Tools like firewalls, endpoint protection, and network monitoring have been crucial, but they've often missed the critical component of the application layer itself. As our applications have transformed into interconnected ecosystems, it's become clear that traditional security measures aren't measuring up. 

The paradigm shift of ADR, which hinges on transforming AppSec from reactive to proactive security, is finally moving the needle. Instead of just detecting threats, new ADR solutions are providing deep insights into application behavior in real-time, allowing us to get ahead of potential issues. It offers unprecedented visibility and response capabilities across distributed architectures, enabling continuous monitoring of runtime behaviors, anomaly detection, and rapid incident response. This shift not only enhances our ability to identify and address threats promptly but also significantly reduces incident response times. 

**Real-Time Visibility Is a Game Changer**

One of the most frustrating aspects of securing modern applications has always been the lack of real-time visibility. Traditional tools offer only a snapshot of an application's security at a specific moment, leaving us blind to what's happening during runtime. ADR integrations are changing this dynamic by utilizing data that's already being collected and turning it into actionable insights. 

It is now possible to continuously map out applications as they evolve, monitoring data flows, API interactions, and third-party integrations. This offers new capabilities to identify potential vulnerabilities and misconfigurations in real-time as applications scale or change in production environments. For instance, the discovery of the ALBeast vulnerability, a critical weakness in AWS's Application Load Balancers (ALBs), was made possible by real-time configuration analysis. This is yet another critical issue that would have otherwise gone unnoticed without ADR tools.

**Proactive, Not Reactive**

Previously, security often meant reacting to issues after they occurred. ADR allows us to get ahead of threats, providing security teams with context about how applications behave and where weaknesses may lie. It doesn't just stop at identifying anomalies, it helps us understand why those anomalies matter and how to address them effectively. 

What excites me most about this is how today's ADR pioneers are complementing existing security measures, like Web application firewalls (WAFs) or authentication controls. These tools often generate large volumes of alerts, many of which turn out to be false positives. With ADR tech, we can cut through that noise, prioritizing threats based on application-specific context and focusing on what really matters. The pragmatist in me is also thrilled to see how ADR enhances the effectiveness of these tools, ensuring that every part of a security stack operates at its full potential. 

**Securing Distributed, Cloud-Native Applications**

As we build more distributed and cloud-native applications, the complexity of these systems will continue to grow. These architectures provide incredible flexibility and scalability, but every integration also opens new attack surfaces. ADR is a field built for this environment, by capitalizing on the wealth of insights provided by runtime behavior across microservices, APIs, and third-party integrations. Application performance and identifying misconfigurations or vulnerable code paths can now be found within a moment. 

**Why Now?**

The timing for the budding ADR market couldn't be better. As the threat landscape continues to evolve, adversaries are getting more sophisticated, targeting weaknesses at the application layer that traditional tools can't catch. We're seeing new types of attacks that exploit the growing complexity of our applications, and ADR allows us to address these threats head-on. By integrating ADR tools and principles into our strategies, we not only respond more quickly, we also enhance overall security across the industry. 

I would also be remiss to downplay another key role of ADR — facilitating better collaboration between development and security teams. With real-time visibility into both the development and runtime phases, security doesn't have to feel like a roadblock anymore. Instead, it's becoming a continuous process that extends throughout the application life cycle. 

**Looking Forward**

While no solution is a silver bullet, ADR represents a significant step forward. By offering a clear window into how applications behave at every stage, we can finally move away from reactive, best-effort security to data-driven, proactive protection. 

For those of us responsible for securing today's complex environments, ADR signifies a much-needed evolution. The future of application security is no longer about reacting to the inevitable; it's about anticipating and preventing attacks before they can cause damage. 

As a chief information security officer, that's a future I'm genuinely excited about.

Why I'm Excited About the Future of Application Security

The "Code-on-Toast" supply chain cyberattacks by APT37 delivered data-stealing malware to users in South Korea who had enabled Toast pop-up ads.

The North Korea-backed advanced persistent threat known as APT37 exploited a zero-day vulnerability in Microsoft's Internet Explorer Web browser over the summer, using it to mount a zero-click supply chain campaign on South Korean targets, researchers revealed.

While IE reached end of life in 2022 and many organizations don't use it anymore, there are plenty of legacy applications that do. In this case, APT37 (aka RedAnt, RedEyes, ScarCruft, and Group123) specifically targeted a Toast ad program that is usually installed alongside various free software, according to AhnLab SEcurity intelligence Center (ASEC). "Toasts" are pop-up notifications that appear at the right-bottom of a PC screen.

"Many Toast ad programs use a feature called WebView to render Web content for displaying ads," according to AhnLab researchers. "However, WebView operates based on a browser. Therefore, if the program creator used IE-based WebView to write the code, IE vulnerabilities could also be exploited in the program."

**A Hot-Buttered Zero-Click Toast Exploit**

According to AhnLab's analysis released last week, the state-sponsored cyberattack group compromised an ad agency, and then used the bug, tracked as CVE-2024-38178 (CVSS 7.5), to inject malicious code into the Toast script the agency uses to download ad content to people's desktops. Instead of ads, the script began delivering malware.

"This vulnerability is exploited when the ad program downloads and renders the ad content," the researchers explained in their report on the attack, which they called "Code on Toast." "As a result, a zero-click attack occurred without any interaction from the user."

The malware delivered is the RokRAT, which APT37 has consistently used in the past.

"After infecting the system, various malicious behaviors can be performed, such as remote commands," the researchers noted, adding, "In this attack, the organization also uses Ruby to secure malicious activity persistence and performs command control through a commercial cloud server."

The campaign had the potential to cause significant damage, they said, but the attack was detected early. "In addition, security measures were also taken against other Toast advertising programs that were confirmed to have the potential for exploitation before the vulnerability patch version was released," according to AhnLab.

**IE Lurks in Apps, Remains a Cyber Threat**

Microsoft patched the bug in its August Patch Tuesday update slate, but the continued use of IE as a built-in component or related module within other applications remains a concerning attack vector, and an incentive for hackers to continue to acquire IE zero-day vulnerabilities.

"Such attacks are not only difficult to defend against with users' attention or antivirus, but can also have a large impact depending on the exploited software," AhnLab researchers explained in the report (PDF, Korean).

They added, "Recently, the technological level of North Korean hacking groups is becoming more advanced, and attacks that exploit various vulnerabilities other than IE are gradually increasing."

Accordingly, users should make sure to keep operating systems and software up to date, but "software manufacturers should also be careful not to use development libraries and modules that are vulnerable to security when developing products," they concluded.

DPRK Uses Microsoft Zero-Day in No-Click Toast Attacks

The European Union adopted a new law setting EU-wide cybersecurity requirements for connected devices to ensure their safety.

The Council of the European Union adopted the Cyber Resilience Act earlier this month, a new law that will ensure that connected devices – including consumer products such as smart doorbells, televisions and toys, as well as commercial devices such as IP cameras – meet new cybersecurity requirements before going to market. 

The new regulations establish an EU-wide framework that encompasses design, development, production and the sale of hardware and software products that connect either directly or indirectly to another device or network. 

The law enhances existing cybersecurity legislation, making regulations more coherent and ensuring that “Internet of Things” (IoT) products are secure from supply chain to end-of-life. It applies to all products connected either directly or indirectly to another device or network.

CRA is designed to allow consumers to make informed decisions when shopping for connected digital products by making it easier for them to identify hardware and software with proper cybersecurity features. New products will be labeled with “CE” to signify they meet the requirements. Products that are already regulated by existing EU rules like medical devices, aeronautical products and cars are exempt from the new regulations.

In the coming weeks the legislative act will be signed by the presidents of the Council and of the European Parliament and be published in the EU’s official journal. The regulation will enter into force 20 days after publication and apply 3 years later, in 2027, although some provisions will apply at earlier stages.

EU Adopts Cyber Resilience Act to Regulate Internet of Things

Microsoft researchers toyed with app permissions to uncover CVE-2024-44133, using it to access sensitive user data. Adware merchants may have as well.

Source: Delphotos via Alamy Stock Photo

A security weakness in the Safari browser on macOS devices might have exposed users to spying, data theft, and other forms of malware.

The issue is enabled by the special permissions Apple gives to its proprietary apps — in this case, its browser — and the ease with which an attacker can reach important app configuration files. In the end, it allows an attacker to bypass the Transparency, Consent, and Control (TCC) security layer that MacBooks use to guard sensitive data. Its CVE entry, CVE-2024-44133, has earned a "medium" severity 5.5 rating in the Common Vulnerability Scoring System (CVSS).

Researchers from Microsoft have named their exploit of CVE-2024-44133 "HM Surf." In a new blog post, they described how HM Surf could open the door to a user's browsing data, camera, and microphone, as well as their device's location, among other things. And the threat doesn't only appear to be theoretical: There's already inconclusive but not insignificant evidence to suggest that one adware program has already exploited CVE-2024-44133, or something quite like it, in the wild.

Apple released a fix for CVE-2024-44133 in its update to macOS Sequoia back on Sept. 16.

"It's a serious concern, because of the unauthorized access it gives," says Xen Madden, cybersecurity expert at Menlo Security, emphasizing the need for organizations to update their macOS devices. But, she adds, "By the looks of it, most EDR tools will detect it, especially since Microsoft Defender is detecting it."

**Exploiting HM Surf**

In any and all Apple devices, TCC is there to manage what sensitive data and features apps can access. If some app wants to access your camera, for example, thanks to TCC, you can rest assured that your Mac will ask for your permission first.

Unless your app has a special "entitlement." Some of Apple's proprietary apps possess entitlements — special permissions, approved by Apple, which allow them unique privileges compared to other apps. The core of why HM Surf works is Safari's entitlement, "com.apple.private.tcc.allow," which allows it to bypass TCC at an app level, and apply it only on a per website ("per origin") basis. In other words, Safari can freely access your camera and microphone as it wishes, but any given website you visit through Safari likely cannot.

Safari's configuration — including the rules that define per-origin TCC protections — are stored in various files under ~/Library/Safari, within the user's home directory. Manipulating these files could provide a path to TCC bypass, though the home directory is itself TCC protected.

Getting around that roadblock is simple, though, using the autological directory service command line utility (DSCL), a tool in macOS for managing directory services from the command line. In HM Surf, DSCL is used to temporarily change the home directory, removing the TCC umbrella shielding ~/Library/Safari. Now they could modify Safari's per-origin TCC configurations — allowing all kinds of permissions for a malicious website of their own creation — before ultimately reinstating the home directory. Thereafter, if a user visited the malicious site, the site would have full rein to capture screenshots, location data, and more, without ever triggering a permission pop-up.

**Was CVE-2024-44133 Already Exploited?**

After concocting their exploit, Microsoft started scanning customer environments for activity that aligned with what they'd found. On one device, lo and behold, they spotted something quite closely resembling what they were looking for.

It was a program digging into the victim's Chrome configuration settings, adding approval for microphone and camera access to a specific URL. It also did more: gathering user and device information, laying the groundwork for a second-stage payload.

This program, it turned out, was a well-known macOS adware program called "AdLoad." AdLoad hijacks and redirects browser traffic, pestering users with unwanted advertisements. It also goes further: harvesting user data, turning infected devices into nodes in a botnet, and acting as a staging ground for further malicious payloads.

In its blog post, Microsoft noted that though AdLoad's activity closely resembled the HM Surf technique, "Since we weren’t able to observe the steps taken leading to the activity, we can’t fully determine if the AdLoad campaign is exploiting the HM surf vulnerability itself." Still, it added, "Attackers using a similar method to deploy a prevalent threat raises the importance of having protection against attacks using this technique."

Dark Reading has contacted both Apple and Microsoft for further comment on this story.

MacOS Safari 'HM Surf' Exploit Exposes Camera, Mic, Browser Data

Adoption of the email authentication and policy specification remains low, and only about a tenth of DMARC-enabled domains enforce policies. Everyone is waiting for major email providers to get strict.

Source: TierneyMJ via Shutterstock

The state of DMARC email authentication and security standard looked so promising at the beginning of 2024.

Google and Yahoo had set a deadline of February 2024 for bulk email senders to adopt a Domain-based Message Authentication, Reporting and Conformance (DMARC) policy, and as companies scrambled to meet the deadline, the number of email domains with a valid DMARC record jumped 60% in two months. As of September, nearly 6.8 million domains have email sender authentication configured.

Even with that surge earlier in the year, the reality is that businesses continue to be slow in setting up email authentication on their domains. The adoption lag is especially pronounced in making the switch from DMARC's minimum-baseline policy of 'p=none' to more stringent policies. Enforcement means non-authenticated emails get quarantined or rejected. The share of DMARC-enabled domains with an enforced policy has actually gone down from a high of 18% a year ago, to less than 14% today.

While Google's and Yahoo's actions forced many companies to adopt DMARC, most of them — spurred by concerns about blocking legitimate messages — haven't adopted the quarantine or reject policies, says Seth Blank, chief technology officer at Valimail, a provider of email security services.

"Google and Yahoo put the requirements out, the ecosystem got a shot in the arm, and the message was heavily about security — so the people who cared about security did something," Blank says. "There's still a large part of this market that has not moved, hasn't taken any steps, even this bare minimum that we're seeing here."

The DMARC protocol aims to add authentication to the Internet's email infrastructure, requiring that email senders adopt two verification technologies — Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) — and specify a policy for how other servers should handle mail from a sender not part of an authorized domain. In October 2023, Google and Yahoo required that email marketers — anyone sending more than 5,000 emails daily through the services — set up DMARC. The move resulted in a significant reduction in non-authenticated emails, with Google seeing two-thirds less (65%) unauthenticated messages sent to Gmail users and 265 billion fewer unauthenticated message sent so far this year, according to company data released last week.

**Fear, Uncertainty, and DMARC**

The adoption rate of DMARC has roughly doubled over the past year — from about 55,000 domains adding new DMARC records each month in 2023, to 110,000 domains per month in Q3 2024, according to Valimail data. Yet, even at that rate, it would still take nearly 15 more years for the top 25 million domains to get on board.

Source: Author, with data from Valimail

Moreover, DMARC adoption has been spotty. While more than 60% of the organizations in some industries, such as manufacturing and healthcare, have adopted DMARC, only one in five have actually moved from the lowest security policy ('p=none') to the highest ('p=reject,') according to data from EasyDMARC, an email-authentication services firm. Some sectors, such as non-profits and charity organizations, have increased adoption over the year, but fewer than 8% of domains are using DMARC.

Because email is critical to business operations, organizations worry that stricter enforcement will result in lost messages, especially because DMARC is not necessary an easy technology to implement and maintain, says Kelly Molloy, director of network development for DomainTools, an internet intelligence firm.

"The fear is, especially if you are a company who depends on leads via email, is that you're going to miss messages from interested parties — from customers and potential customers — if you start doing \[strict enforcement\]," she says, adding: "A lot of companies are being conservative and are not going farther than they really need to ... because it does take resources."

**Waiting for the Other Shoe to Drop**

The stalled adoption cycle will likely attract another major move by Google, Yahoo and other large consumer email services, says Hagop Khatchoian, technical services team lead at EasyDMARC.

"They \[Google and Yahoo\] are just forcing everyone to have at least 'p=none' ... to just have a basic policy without any enforcement — we foresee that will be changed in the next few years," he says. "But you can't just go on and tell everyone, 'Hey, you need 'p=reject,' ... because if you have a small misconfiguration in your email ecosystem, and you have an enforced policy, then your own legitimate emails will be blocked as well."

Valimail's Blank agrees, noting that the major email services — Google, Microsoft and Yahoo, as well as major email providers in other countries — are unlikely to wait long before again turning the screws on unauthenticated email.

"The sending community or the receiving community will mandate the next steps, because they know \[authentication\] is the single most important input into their system — being able to know who sent an email with far more certainty," he says. "We're going to see more action there ... and it will take years, but it's not going to be five to ten years. It's probably two, three, maybe four."

**None's Not Nothing, But Close to It**

With another DMARC-push in the cards from major email services, organizations should plan to shift their DMARC policy from 'none' to a higher level of enforcement.

The three levels of enforcement are:

*   p=none — Mail that fails authentication checks are still delivered.
    
*   p=quarantine — Any authentication failure results in email being quarantined, possibly delivered to a user's spam folder or to an organization's quarantine storage.
    
*   p=reject — Authentication failure leads to the email being discarded, although some service providers may instead quarantine the email in a separate folder.
    

Every enforcement level can produce reports, and companies should monitor the reports to check for issues and anomalies, says Valimail's Blank.

"DMARC at 'p=none' with no reporting is syntactically equivalent to not having DMARC at all," he says. "The value of DMARC comes from reporting and working towards a policy that is not 'none.' If you have 'p=none', and you're not getting reports, there is nothing you can do, there is nothing you can see, there is nothing you can fix."

Getting reports from the DMARC infrastructure is important level of visibility for companies as they pursue better email security. Large companies are not the only organizations to see significant abuse of email, so any firms that sends email should monitor their DMARC reports, he says.

Time to Get Strict With DMARC

Security firm ESET is refuting reports that cyberattackers compromised its platforms and used them to target customers in Israel with dangerous wiper malware. However, it did note that a partner there, Comsecure, was impacted.

"We are aware of a security incident which affected our partner company in Israel last week," the firm acknowledged on social media platform X. "Based on our initial investigation, a limited malicious email campaign was blocked within ten minutes. ESET technology is blocking the threat and our customers are secure. ESET was not compromised and is working closely with its partner to further investigate and we continue to monitor the situation."

Security researcher Kevin Beaumont (aka Gossi the Dog) prompted the response after blogging about a malicious email that an ESET user posted on the ESET user forum. The email was flagged as malicious, with the subject line, "Government-Backed Attackers May Be Trying to Compromise Your Device!" It purported to be from the ESET team, offering extra security defense in the face of an ongoing attack:

The email had a .ZIP attachment that, if opened, unpacked a destructive wiper malware that bears resemblance to that used by the Handala threat group, according to the person who flagged the email for Beaumont. Handala, so named for the political cartoon character that has come to personify the Palestinian people’s national identity, is known for targeting Israeli organizations with file-destroying wipers in the wake of the Oct. 7 Hamas attacks and resulting war.

Beaumont noted, "I managed to obtain the email, which passes both DKIM and SPF checks for coming from ESET’s store," he said in the blog post. "Additionally, the link is indeed to backend.store.eset.co.il — owned by ESET Israel."

This led Beaumont to conclude via Mastodon, "ESET Israel definitely got compromised, this thing is fake ransomware that talks to an Israeli news org server for whatever reason."

ESET has now categorically refuted that takeaway, so the assumption is that the cyberattackers were using some sort of MO to get around anti-spoofing measures for the email and the .ZIP link. ESET did not immediately return a request for comment from Dark Reading for more information on Comsecure's role in the incident and the attack routine.

The campaign is now blocked for ESET customers.

ESET-Branded Wiper Attack Targets Israel; Firm Denies Compromise

A survey shows three-quarters of CISOs are drowning in threat detections put out by a sprawling stack of tools, yet still lack the basic visibility necessary to identify breaches.

Global information security spend is projected to reach $215 billion by the end of 2024. But a new survey of chief information security officers (CISOs) shows that all that cash might not have bought the peace of mind they hoped for. In fact, 44% of CISOs across the globe reported missing a data breach in the past 12 months with existing tools.

The top blind spot identified in the survey of 234 global CISOs was hybrid cloud infrastructure and data-in-transit, which eight out of 10 of those surveyed by Gigamon said is a "top concern." Gigamon's report added that data-in-motion is where 93% of malware has historically hidden. Overwhelmingly, 84% of surveyed CISOs said getting visibility into this encrypted traffic was a top priority for the upcoming year.

"Modern cybersecurity is about differentiating between acceptable and unacceptable risk," Chaim Mazal, CSO at Gigamon, said in the survey report. "Our research shows where CISOs are drawing that line, highlighting the critical importance of visibility into all data-in-motion to secure complex hybrid cloud infrastructure against today’s emerging threats. It’s clear current approaches aren’t keeping pace, which is why CISOs must reevaluate tool stacks and reprioritize investments and resources to more confidently secure their infrastructure."

**The Cloud and Cyber Threat Observability**

Deep observability into hybrid cloud environments is top of mind for 82% of surveyed CISOs. And 85% of those surveyed would like to gain visibility into packet-level and application metadata. Boards too agree that this deep observability is critical, with 81% of CISOs reporting hybrid cloud infrastructure will be a budgeting priority in 2025.

"Today’s CISOs recognize that security and observability are intrinsically connected," Stephen Elliott, group vice president, IT operations, observability, and CloudOps at IDC, said in the report. "The network provides a crucial layer of context that can inform security operations and vice versa, which is why modern security teams are leveraging network-derived intelligence and insights to understand the true impact of a threat and prioritize their responses accordingly."

But before CISOs start spending on new tools, they plan to get the most out of what they already have, according to the survey. Three-quarters of those CISOs surveyed reported being "overwhelmed" by the growing number of tools and their alerts. So to get a better handle on hybrid cloud data and infrastructure, for instance, 60% of CISOs said their top priority for 2025 will be to consolidate and optimize existing tools for that arena.
