"Midnight Blizzard," a threat group linked to Russia's foreign intelligence service, is stoking more concern than usual for both its sheer scope and its use of a new tactic for harvesting information and gaining control of victim systems.

Microsoft this week said its threat intelligence group observed Midnight Blizzard actors sending out thousands of spear-phishing emails to targeted individuals at more than 100 organizations worldwide since Oct. 22.

**Large-Scale Campaign**

Besides its wide scope, the campaign is noteworthy for Midnight Blizzard's use of a digitally signed Remote Desktop Protocol (RDP) configuration file in its spear-phishing emails. The RDP file connects to a server controlled by a threat actor; when the file is opened, it allows the attacker to harvest user credentials and detailed system information to aid further exploit activity.

"The emails were highly targeted, using social engineering lures relating to Microsoft, Amazon Web Services (AWS), and the concept of zero trust," Microsoft said on its threat intelligence group blog this week. "Microsoft has observed this campaign targeting governmental agencies, higher education, defense, and non-governmental organizations in dozens of countries, but particularly in the UK, Europe, Australia, and Japan."

Midnight Blizzard — aka Cozy Bear, APT29, and UNC2452 — has been the proverbial thorn in the side of security organizations for some years now. The group's many victims include SolarWinds, Microsoft, HPE, multiple US federal government agencies, and diplomatic entities worldwide. Its well-documented tactics, techniques, and procedures (TTPs) include using spear phishing, stolen credentials, and supply chain attacks for initial access. Midnight Blizzard actors have also targeted vulnerabilities in widely used networking and collaboration technologies such as those from Fortinet, Pulse Secure, Citrix, and Zimbra to gain an initial toehold on a target network.

**Bidirectional Connection**

The RDP file in the Microsoft, AWS, and zero-trust themed emails in Midnight Blizzard's latest campaign allows the attacker to establish a quick, bidirectional connection with a compromised device. The threat actor is using it to harvest a range of information including user credentials, files, and directories on the victim system and connected network drives; information from connected smart cards and other peripherals; Web authentication credentials; and clipboard data. The RDF file is signed with a LetsEncrypt certificate to lend it an air of legitimacy. "This access could enable the threat actor to install malware on the target's local drive(s) and mapped network share(s), particularly in AutoStart folders, or install additional tools such as remote access Trojans (RATs) to maintain access when the RDP session is closed," Microsoft cautioned.

Stephen Kowski, field CTO at SlashNext, says Midnight Blizzard's use of signed RDP files in its current campaign is significant. Signed RDP files can bypass traditional security controls since they appear to come from a legitimate source, he points out.

"This technique is particularly cunning because RDP files are commonly used in business environments, making them less likely to raise immediate suspicion, while the legitimate signature helps evade standard malware detection systems," he says. He advocates that organizations scan all email attachments in real time, with a particular focus on RDP files and other seemingly legitimate Microsoft-related content. "The use of legitimately signed files creates a significant blind spot for conventional security tools that rely heavily on signature-based detection or reputation scoring," Kowski advises.

**Mitigating the Threat**

Microsoft has released a list of indicators of compromise for the new Midnight Blizzard campaign, including email sender domains, RDP files, and RDP remote computer domains. It has recommended that security teams review their organizational email security settings and antivirus and anti-phishing measures; turn on Safe Links and Safe Attachments settings in Office 365; and enable measures for quarantining sent email if needed. Other recommendations include using firewalls to block RDP connections, implementing multifactor authentication, and strengthening endpoint security configurations.

Venky Raju, field CTO at ColorTokens, says the campaign is a reminder why organizations need to maintain a tight rein over the use of Microsoft's remote desktop. While it can be useful to share devices, folders, and clipboard content over an RDP session, it gives attackers a way into a user's device. "Signing the RDP configuration file may prevent email security systems from classifying the email as having a suspicious link or attachment. It may also reduce the warnings presented by the RDP client," he points out.

'Midnight Blizzard' Targets Networks With Signed RDP Files

A malvertising campaign is exploiting Meta’s platform to spread SYS01 infostealer, targeting men 45+ via fake ads for…

A malvertising campaign is exploiting Meta’s platform to spread SYS01 infostealer, targeting men 45+ via fake ads for popular software. The malware steals Facebook credentials, hijacks accounts espicially those administrating business pages, and spreads further attacks globally.

A new malvertising campaign is exploiting Meta’s advertising platform to spread the **SYS01 infostealer**, a cybersecurity threat known to Meta and particularly Facebook users for stealing their personal information.

What makes this attack targeted is that millions of users globally, specifically men aged 45 and above, are potential victims of this ongoing attack, which cleverly disguises itself as advertisements for popular software, games, and online services.

This campaign, first detected in September 2024, stands out due to its impersonation tactics and popular brands that it exploits. Instead of focusing on a single lure, the attackers mimic a broad range of trusted brands, including productivity tools like Office 365, creative software like Canva and Adobe Photoshop, VPN services like ExpressVPN, streaming platforms like Netflix, messaging apps like Telegram, and even popular video games like Super Mario Bros Wonder.

****How the Attack Works:****

According to Bitdefender’s **blog post** shared with Hackread.com ahead of publishing on Wednesday, the malicious ads often lead to MediaFire links offering direct downloads of seemingly legitimate software. These downloads, packaged as zip archives, contain a malicious Electron application.

Once executed, this application drops and **runs the SYS01 infostealer**, often while displaying a decoy app that mimics the advertised software. This deceptive tactic makes it difficult for victims to realize they’ve been compromised.

For your information, an Electron application is a type of desktop app built with web technologies like HTML, CSS, and JavaScript. Electron is an open-source framework developed by GitHub that allows developers to create cross-platform applications that run on Windows, macOS, and Linux, all from a single codebase.

In this attack however, behind the scenes, the Electron app uses obfuscated Javascript code and a standalone 7zip executable to extract a password-protected archive containing the core malware components. This archive includes PHP scripts responsible for **installing the infostealer** and establishing persistence on the victim’s system. The malware also incorporates anti-sandbox checks to evade detection by security researchers.

****Stealing Data and Hijacking Accounts:****

The primary goal of the SYS01 infostealer is to harvest Facebook credentials, particularly those associated with business accounts. These compromised accounts are then used to further attacks/scams.

What’s worse, the attack also leverages the advertising capabilities of hijacked accounts, allowing attackers to create **new malicious ads** that appear more legitimate and easily bypass security filters. This creates a self-sustaining cycle where stolen accounts are used to spread the malware even further. The stolen credentials are also likely sold on underground marketplaces, further enriching the criminals.

****Global Reach and Protection****

While the campaign has a global reach, impacting users in the EU, North America, Australia, and Asia, Bitdefender could not verify the full extent of its impact, especially outside the EU, which remains unclear due to limited data transparency.

Nevertheless, if you are on Facebook—especially if you run a business page—you must watch out for SYS01 Infostealer and **similar threats**. While using common sense is essential, here are some vital steps you should take:

1.  **Monitor your accounts:** Regularly check your Facebook and other social media accounts for suspicious activity. Report any unauthorized access immediately and change your passwords.
2.  **Be wary of ads:** Exercise caution when clicking on ads, especially those offering free downloads or deals that seem too good to be true. Verify the source before downloading any software.
3.  **Stick to official sources:** Download software directly from official websites or trusted app stores. Avoid third-party platforms and file-sharing services.
4.  **Use strong security software:** Install reputable security software and keep it updated. Choose a solution that offers real-time protection and advanced threat detection.
5.  **Enable two-factor authentication (2FA):** Activate 2FA on your Facebook and other important online accounts for added security.

2.  **ALPHV Ransomware Uses Google Ads to Target Victims**
3.  **Fake WhatsApp clone steals crypto on Android and Windows**
4.  **Facebook, Meta, Apple, Amazon Most Impersonated in Scams**
5.  **Fake ChatGPT and Facebook Ads Used in DNS Investment Scam**

A former Disney employee was arrested and charged after allegedly hacking into the company's systems and altering its restaurant menus.

Michael Scheuer, an ex-menu production manager at Disney, was charged with violating the Computer Fraud and Abuse Act (CFAA) on three different occasions.

He was fired from this position in June, after unspecified misconduct; his dismissal was described as "contentious" and "not considered to be amicable," according to court documents.

Scheuer allegedly used his work credentials, which were still functioning after his termination, to log into the Disney menu creation system contracted by a third-party company and change the fonts in the system to Wingdings symbols.

When the menu creator was launched, it would reach for these altered font files, believing them to be correct. 

"As a result of this change, all of the menus within the database were unusable because the font changes propagated throughout the database," read the complaint.

Scheuer also allegedly deleted allergen information from the menus, suggesting some foods were safe when they weren't, leading to potentially deadly consequences. The menus were identified and isolated by Disney before they could be shipped.

The menu changes caused the system to go offline for a couple of weeks and required backup to restore.

Scheuer has also been accused of being the root cause of several distributed denial-of-service attacks against several Disney employees, their information found in a folder on one of Scheuer's virtual machines, labeled "dox." According to the FBI, the evidence found in the investigation pointed to Scheuer as the perpetrator. He has been charged on two violations of the CFAA and remains in jail pending a bond hearing. If found guilty, he faces up to 15 years in prison.

TEL AVIV-YAFO, Israel – Oct. 29, 2024 – Zenity, the leader in securing agentic AI, today announced they have received $38 million in Series B funding co-led by Third Point Ventures and DTCP, pushing the total capital raised to over $55 million. It follows the recent strategic investment by Microsoft’s venture arm M12, with strong support from existing investors Intel Capital and Vertex Ventures. The funds will be used to grow the team across product, engineering, sales, and marketing, as well as launching a partner program to expand the ecosystem of supporting enterprises globally as they adopt agentic workflows including agentic AI, enterprise copilots, and applications built on low-code platforms. With Forbes estimating more than 51% of companies are actively adopting AI for process automation, and Microsoft stating the number of people who use Copilot daily at work has nearly doubled quarter-over-quarter, many enterprises have already taken a bold leap into the world of AI. However, per Salesforce, only 11% of CIOs say they’ve fully implemented AI, with the number one reason for holding full implementation back being around security and data infrastructure concerns. This round of funding serves to further accelerate and expand Zenity’s ability to enable the use of AI apps and agents among Fortune 500 enterprises, including current Zenity customers that exist across financial services, technology, manufacturing, energy and pharmaceutical industries.

Ben Kliger, Zenity’s CEO and co-founder, said: “The future of work is now. For the first time, large enterprises are on the cutting edge by placing the power of AI and low-code at all users’ fingertips, meaning anyone can now use and build AI agents and business applications to get more done. As such, security teams need robust and purpose-built solutions to properly manage the risks that come when utilizing the most powerful tools we have ever seen. We are proud to partner with Third Point Ventures and DTCP to continue our mission in supporting the world’s largest and most consequential organizations to enable innovation securely.” Recently, Zenity researchers found that the average large enterprise has nearly 80,000 AI agents, apps, and automations that are built using low-code development platforms, with over 62% containing some type of security vulnerability. Additionally, Zenity CTO and co-founder Michael Bargury presented research at Black Hat 2024 revealing how easy it is for bad actors to take control over enterprise copilots, such as Microsoft 365 Copilot, all without requiring a compromised account. What these themes have in common, is that business users of all technical backgrounds are at the forefront for business productivity. It also means that IT organizations are lacking visibility, as AI agents and applications are being built and used across the enterprise. These applications exist with an implicitly shared responsibility model, similar to the cloud, and security teams do not have visibility into what risks exist. Zenity provides visibility, risk assessment, and governance that security teams need in order to fully harness AI agents. Having gotten their start as the pioneers in the low-code/no-code application security space, Zenity is uniquely positioned with this latest round of funding to support enterprises as they continue placing more power at the hands of business users via Agentic AI workflows. As a community-oriented organization, having led and co-sponsored initiatives like the OWASP Top 10 for Low-Code/No-Code Security and the newly minted GenAI Attacks Matrix, Zenity is at the forefront of both security research and product development to be able to continue as a force enabler to the world’s enterprises. 

Sapir Harosh, Partner, Third Point Ventures, said: “In the rapidly evolving realms of AI and low-code development, Zenity stands out as a first mover dedicated to securing enterprises from emerging threats. We are proud to invest in Zenity and work closely with the team as they enable enterprises to harness powerful tools safely and drive transformative change. At Third Point Ventures, we are on the lookout for visionary companies like Zenity—those with deep connections to technology and a bold mission to serve large enterprises. We look forward to supporting their next wave of growth as they continue to innovate with advancements in AI and low-code technologies.” 

Dean Shahar, Head of Israel, DTCP, said: “We are incredibly impressed with Zenity’s achievements and are thrilled to partner with them in their next phase of growth. It’s no secret that the race to secure AI is on, but Zenity is way ahead of the competition, driven by a strong customer base and over 3x YoY growth. Their research-driven and community-focused approach, combined with their expertise in securing and understanding low-code environments, gives them a distinctive advantage in securing how business users operate today – one that’s already delivering real value to their customers. We’re excited about the opportunity to work with Ben, Michael and their incredible team and look forward to a fruitful collaboration that drives innovation and success.”

PRESS RELEASE

RALEIGH, N.C., Oct. 28, 2024 /PRNewswire-PRWeb/ -- ALL THINGS OPEN 2024 -- After a year-long, global, community design process, the Open Source Definition (OSAID) v.1.0 is available for public use.

The release of version 1.0 was announced today at All Things Open 2024, an industry conference focused on common issues of interest to the worldwide Open Source community. The OSAID offers a standard by which community-led, open and public evaluations will be conducted to validate whether or not an AI system can be deemed Open Source AI. This first stable version of the OSAID is the result of multiple years of research and collaboration, an international roadshow of workshops, and a year-long co-design process led by the Open Source Initiative (OSI), globally recognized by individuals, companies and public institutions as the authority that defines Open Source.

"The co-design process that led to version 1.0 of the Open Source AI Definition was well-developed, thorough, inclusive and fair," said Carlo Piana, OSI board chair. "It adhered to the principles laid out by the board, and the OSI leadership and staff followed our directives faithfully. The board is confident that the process has resulted in a definition that meets the standards of Open Source as defined in the Open Source Definition and the Four Essential Freedoms, and we're energized about how this definition positions OSI to facilitate meaningful and practical Open Source guidance for the entire industry."

"The new definition requires Open Source models to provide enough information about their training data so that a 'skilled person can recreate a substantially equivalent system using the same or similar data,' which goes further than what many proprietary or ostensibly Open Source models do today," said Ayah Bdeir, who leads AI strategy at Mozilla. "This is the starting point to addressing the complexities of how AI training data should be treated, acknowledging the challenges of sharing full datasets while working to make open datasets a more commonplace part of the AI ecosystem. This view of AI training data in Open Source AI may not be a perfect place to be, but insisting on an ideologically pristine kind of gold standard that will not actually be met by any model builder could end up backfiring."

"We welcome OSI's stewardship of the complex process of defining Open Source AI," said Liv Marte Nordhaug, CEO of the Digital Public Goods Alliance (DPGA) secretariat. "The Digital Public Goods Alliance secretariat will build on this foundational work as we update the DPG Standard as it relates to AI as a category of DPGs."

"Transparency is at the core of EleutherAI's non-profit mission. The Open Source AI Definition is a necessary step towards promoting the benefits of Open Source principles in the field of AI," said Stella Biderman, executive director at the EleutherAI Institute. "We believe that this definition supports the needs of independent machine learning researchers and promotes greater transparency among the largest AI developers."

"Arriving at today's OSAID version 1.0 was a difficult journey, filled with new challenges for the OSI community," said OSI Executive Director, Stefano Maffulli. "Despite this delicate process, filled with differing opinions and uncharted technical frontiers—and the occasional heated exchange—the results are aligned with the expectations set out at the start of this two-year process. This is a starting point for a continued effort to engage with the communities to improve the definition over time as we develop with the broader Open Source community the knowledge to read and apply OSAID v.1.0."

PRESS RELEASE

LONDON, Oct. 28, 2024 /PRNewswire/ -- VIPRE Security Group, a global leader and award-winning cybersecurity, privacy, and data protection company, has released its Q3 2024 Email Threat Trends Report, shedding light on the evolving cybersecurity landscape. This comprehensive analysis of real-world data reveals the sophisticated strategies and techniques employed by cybercriminals, with a particular persistent focus on the highly lucrative tactic of business email compromise (BEC). VIPRE processed 1.8 billion emails globally, of which 208 million were malicious.

BEC impersonation weaponisation  

In this third quarter of 2024, cybercriminals intensified their efforts to exploit organisational vulnerabilities through employee deception. BEC scams surged, accounting for 58% of phishing attempts. Notably, 89% of these BEC attacks involved impersonation of authority figures, including CEOs, senior executives, and IT staff, underscoring the sophisticated tactics employed by malicious actors.

BEC aims for the manufacturing sector 

The manufacturing sector saw a significant rise in BEC attacks, potentially driven by financial fraud. These incidents increased from just 2% in Q1 to 10% in Q3 this year. This rise may be attributed to the industry's widespread use of mobile sign-ins at various worksites. Employees accessing systems "on the go", often under pressure to meet production deadlines, are more susceptible to phishing attempts.

Subtler tactics are a larger threat

Email threats in Q3 were dominated by scams (34%), commercial spam (30%), and phishing (20%). These email threats overshadowed ransomware and malware combined, which comprised less than 20% of all email attacks. Interestingly, despite their lower prevalence, ransomware and malware continue to receive disproportionate attention from the cybersecurity industry.

Sneakier attachments 

To counter advancing email security solutions, criminals are deploying increasingly more intricate methods to bypass defenses. Attackers are employing sneakier techniques such as disguising malicious attachments as voicemail recordings or critical security updates to lure unsuspecting users into downloading them.

Additionally, Microsoft PDFs and .DOCX files remain the most common forms of malicious attachments. In Q3 2024, 2.18 million emails were detected containing harmful attachments, marking a 30% increase from the previous quarter's 21% attachment-based attacks.

Phishing links and compromised websites

Cybercriminals continue to favour the URL redirection technique, a tactic that typically proves effective at evading security controls. This deceptive ploy utilises a "clean" URL within the body of the email, which then redirects unsuspecting users to a malicious one once inside. In Q3 2024, URL redirection accounted for 52% of such attacks, leading victims to meticulously crafted fraudulent websites designed to appear authentic, and gain trust.

Malspam pendulum swing from malicious links to attachments

When it comes to malspam, there is a pendulum swing from a preference for malicious links to attachments. During Q3, malspam efforts were centered on malicious attachments (64%), while only 36% employed a link. The attachment formats used were predominantly LNK, ZIP, and DOCX. Only a quarter ago, links were the tool of choice by a factor of nearly nine-to-one (86% links to 14%).

The 'Malware Family of the Quarter' goes to Redline

Redline is the top malspam family of Q3 2024, a spot it has maintained since the corresponding quarter in 2023. RedLine is designed to steal sensitive information from web browsers, such as credentials and payment data. Typically distributed via phishing emails or malicious websites, it sends stolen data to a command-and-control server controlled by the attacker. It can completely take over a compromised machine and uses multiple infiltration methods.

"The findings of this report yet again illustrate the sophistication of criminal tactics. BEC email and phishing attacks are becoming more targeted and convincing," Usman Choudhary, CPTO, VIPRE Security Group, says. "Additionally, malware distribution through malicious spam campaigns continues to pose a serious threat to organisations. These findings stress the critical need for robust cybersecurity measures and ongoing employee education to combat these evolving threats, especially as bad actors gear up for the upcoming holiday season – Black Friday, Thanksgiving, Christmas, and New Year."

Business Email Compromise (BEC) Impersonation: The Weapon of Choice of Cybercriminals

From bulletproof glass, drones, and snipers to boulders blocking election offices, the US democratic system is bracing for violent attacks in 2024.

Drones, snipers, razor wire, sniffer dogs, body armor, bulletproof glass, and 24-hour armed security.

This is not a list of protections in place for a visit by the president of the United States nor the contents of a shipment to frontline troops fighting in Ukraine. This is a list of the security measures election officials in counties across the US have had to implement ahead of Tuesday’s vote as a result of the unprecedented threats they have faced in recent years.

Officials are putting in place the typical final measures to ensure the smooth operation of an election, but beyond checking that they have enough ballots and that machines are working properly, officials are now faced with having to monitor for threats and make sure they have done everything they can to protect themselves and their staff.

“Given the current political environment, the possibility that an event may occur has increased, and our election professionals have responded in kind,” says Tammy Patrick, a former election official in Arizona’s Maricopa County who is now a senior adviser at the nonprofit Bolstering Elections Initiative. “Efforts focusing on the physical security of the voters, election workers, and staff by putting in bulletproof glass, panic buttons, razor wire, and fencing are fairly common, as is the installation of surveillance cameras and systems, cyber protections, and training on de-escalation techniques and response drills.”

Nowhere in the US is the militarization of the election process more evident than in Maricopa County.

The fourth largest county in the nation, Maricopa became ground zero for election denial conspiracists in recent years, after GOP lawmakers sanctioned a bogus recount in 2021, run by the Florida company Cyber Ninjas.

As a result, the county has for years been putting increased security measures in place. “We're a fortress now,” Stephen Richer, the Maricopa County Recorder, told WIRED back in February, outlining how he had to navigate security fencing, metal detectors, and security checks in order to get into his office.

As the 2024 election approaches, the measures Maricopa officials are putting in place have been ratcheted up significantly.

Officials have added a second layer of security fencing to protect election offices, as well as concrete k-rails, which means election workers will be bused in from offsite locations due to reduced parking spaces. At the country’s tabulation center, every door will be fitted with metal detectors, floodlights will be installed, and on election day the center will be protected by a ring of snipers deployed on roofs around the building, election officials told NBC.
