Data Privacy / Mobile Security

Apple has released iOS and iPadOS updates to address two security issues, one of which could have allowed a user's passwords to be read out aloud by its VoiceOver assistive technology.

The vulnerability, tracked as CVE-2024-44204, has been described as a logic problem in the new Passwords app impacting a slew of iPhones and iPads. Security researcher Bistrit Daha has been credited with discovering and reporting the flaw.

"A user's saved passwords may be read aloud by VoiceOver," Apple said in an advisory released this week, adding it was resolved with improved validation.

The shortcoming impacts the following devices -

*   iPhone XS and later
*   iPad Pro 13-inch
*   iPad Pro 12.9-inch 3rd generation and later
*   iPad Pro 11-inch 1st generation and later
*   iPad Air 3rd generation and later
*   iPad 7th generation and later, and
*   iPad mini 5th generation and later

Also patched by Apple is a security vulnerability (CVE-2024-44207) specific to the newly launched iPhone 16 models that allows audio to be captured before the microphone indicator is on. It's rooted in the Media Session component.

"Audio messages in Messages may be able to capture a few seconds of audio before the microphone indicator is activated," the iPhone maker noted.

The problem has been fixed with improved checks, it added, crediting Michael Jimenez and an anonymous researcher for reporting it.

Users are advised to update to iOS 18.0.1 and iPadOS 18.0.1 to safeguard their devices against potential risks.

Apple Releases Critical iOS and iPadOS Updates to Fix VoiceOver Password Vulnerability

CVE-2024-44204 is one of two new Apple iOS security vulnerabilities that showcase an unexpected coming together of privacy snafus and accessibility features.

Apple has patched two quirky bugs that might have offended privacy-oriented iPhone and iPad owners.

The first — an issue with Apple's VoiceOver accessibility feature — could have caused iPhones or iPads to announce sensitive passwords out loud. The other issue — affecting voice messages on new iPhone models — could have recorded users for brief seconds before they knew they were being recorded.

New operating system versions are available for both iOS and iPadOS (18.0.1), fixing each bug with improved validation and checks, respectively. Users should update their devices to avoid being vulnerable.

As Michael Covington, vice president of portfolio strategy for Jamf points out, "The good news is that neither of these highlighted issues involve remote exploits. They are, in fact, issues that will arise with use of the device, and it's user privacy that is ultimately at risk."

Still, he says that "for businesses that use mobile in any capacity for work, I recommend they pay close attention to both of the security issues and take appropriate action to update devices as soon as possible."

**Bug #1: Reading Passwords Aloud**

The first issue involves VoiceOver, the accessibility feature that provides visually impaired users with audible descriptions of the various elements on their screens — text, buttons, images, etc. VoiceOver also allows users to navigate their devices using voice commands and gestures.

Perhaps not everything on a device should be read aloud, though, like passwords. Last month, as part of iOS and iPadOS 18, Apple released a brand new app, "Passwords," allowing users to easily store and manage logins on their devices. CVE-2024-44204 is a logic issue that could have allowed VoiceOver to read out such a user's passwords. It affected essentially every model of iPhone and iPad released since 2018.

VoiceOver is off by default, meaning that only select iPhone users were potentially affected.

Covington notes, "This is not the first time we've seen accessibility features misused. Previous instances include screen reader technology being used by misbehaving apps to capture on-screen details and exfiltrate data from the device. Fortunately, most accessibility features go through extensive security and privacy testing, so these scenarios do not tend to arise often."

**Bug #2: Beginning Audio Messages Too Early**

If iPhone users are on the go, have a lot to say, or maybe just have tired thumbs, they might choose to record an audio message in iMessage, instead of a regular text. After they hit that plus sign on the left side of the message box and choose "Audio," the device will indicate that it has started recording with a red-highlighted sound wave in place of the message box, and a little orange dot in the pill-sized Dynamic Island at the top of the screen.

A security researcher recently discovered though that audio messages could have captured a few seconds of audio before users were made aware that their microphone was hot. The issue has been labeled CVE-2024-44207, and affects all models of the new iPhone 16.

Though it might seem — and, in most cases, would be — a relatively minor issue, Covington points out, "this disconnect between device function and the associated visual indicators is something that Jamf’s own threat research team has connected to persistence techniques used by attackers to maintain a presence on the device following a successful exploit. Addressing this bug before it can be misused is a big win for Apple."

Neither the VoiceOver nor the audio message vulnerability has received a rating in the Common Vulnerability Scoring System (CVSS) yet, nor are any further details public at this time.

Computer Laboratory Management System 2024 1.0 Cross Site Scripting

It's North Korea versus Cambodia, with Windows default settings and sheer patience allowing the bad guys to avoid easy detection.

The North Korean state-sponsored threat actor known as APT37 has been carefully spreading a novel backdoor, dubbed "VeilShell." Of note is its target: Most North Korean advanced persistent threats (APTs) have a history of targeting organizations in South Korea or Japan, but APT37's latest campaign seems to be directed at a nation Kim Jong-Un has more complex relations with: Cambodia.

While Pyongyang still maintains an embassy in Phnom Penh and the two nations share a history of Soviet ties in the region, the modern-day relationship between the two is far from cozy. The DPRK's nuclear weapons program, ongoing missile tests, cyber activities, and general aggression towards its neighbors contradicts Cambodia's stance on weapons of mass destruction (WMDs) and its call for meaningful diplomatic dialogue between all countries in the region, observers in the region have noted.

That wariness has drawn the attention of the North Korean regime, according to Securonix, which has flagged a new campaign called "Shrouded#Sleep" circulating against Cambodian organizations.

Securonix did not share detailed victimology, but to lure in targets, APT37 (aka InkSquid, RedEyes, BadRAT, Reaper, ScarCruft, and Ricochet Chollima) has been spreading malicious emails relating to Cambodian affairs, and in Cambodia's primary language, Khmer. One lure for instance offers recipients access to a spreadsheet related to annual income in US dollars across various sectors in the country, such as social work, education, health, and agriculture.

Hidden in these emails are maliciously crafted shortcut files concealing the backdoor, used to establish quiet persistence in targeted networks.

**Shrouded#Sleep's Stealthy Shortcuts**

In terms of the infection routine, a Shrouded#Sleep infection begins, like many others do, with a .ZIP archive containing a Windows shortcut (.LNK) file.

"It's incredibly common — if you were to throw a dart at the threat actor dartboard, a shortcut file is probably going to be hit," says Tim Peck, senior threat researcher at Securonix. "It's easy, it's effective. It pairs really well with phishing emails. And it's easy to mask."

Windows hides the .LNK file extension by default, substituting it with a little arrow in the bottom left hand corner of a file's icon, making for an overall cleaner user interface. The upshot is that attackers like APT37 can swap a .LNK's default icon with another of their choosing, and use double extensions to hide the true nature of the file.

APT37 gives its shortcut files PDF and Excel icons, and assigned them double extensions like ".pdf.lnk," or ".xls.lnk," so that only the .PDF and .XLS parts of the extension show up for users.

In the end, Peck notes, "Unless you're looking for the little arrow that Microsoft adds on shortcut files, odds are you might miss that." An unreasonably eagle-eyed victim might also have noticed that unlike typical shortcut files — which tend to be just a few kilobytes in size — these were anywhere from 60 to 600 kilobytes.

Contained within those kilobytes was APT37's malicious payload, which Securonix has named "VeilShell." 

**VeilShell's Patient Persistence**

The SHROUDED#SLEEP campaign is notable for its state-of-the-art blend of living-off-the-land and proprietary tools, plus impressive persistence and stealth mechanism.

"It represents a sophisticated and stealthy operation targeting Southeast Asia leveraging multiple layers of execution, persistence mechanisms, and a versatile PowerShell-based backdoor RAT to achieve long-term control over compromised systems," according to the Securonix analysis. "Throughout this investigation, we have shown how the threat actors methodically crafted their payloads and made use of an interesting combination of legitimate tools and techniques to bypass defenses and maintain access to their targets."

Related:China's 'Earth Baxia' Spies Exploit Geoserver to Target APAC Orgs

VeilShell for instance is a multifunctional, PowerShell-based backdoor-plus-remote-access-trojan (RAT). It's capable of all the things RATs tend to do: download and upload files, modify and delete existing files on the system, modify system settings, create scheduled tasks for persistence, etc.

Notably, APT37 also achieves persistence via AppDomainManager injection, a rarer technique involving the injection of malicious code into .NET applications.

All of these malicious functions and techniques might otherwise make a lot of noise on targeted systems, so APT37 uses some tricks to provide counterbalance. For example, it implements long sleep timers to break up different stages of the attack chain, ensuring that malicious activities don't occur in obvious succession.

As Peck tells it, "The threat actors were incredibly patient, slow, and methodical. They used a lot of long sleep timers — we're talking, like, 6,000 seconds in between different attack stages. And the main goal \[of the shortcut file\] was to set the stage. It didn't actually execute any malware. It dropped the files into a location that would allow them to execute on their own on the next system reboot. That reboot could be the same day, or a week from now, depending on how the user uses their PC."

It was emblematic, perhaps, of a threat actor with confidence and patience to spare. "A lot of times we see these dive in, dive out types of campaigns. But this was definitely designed with stealth in mind," he says.

NIST standardized three algorithms for post-quantum cryptography. What does that mean for the information and communications technology (ICT) industry?

Source: Cynthia Lee via Alamy Stock Photo

COMMENTARY

After a grueling eight years of testing, the National Institute of Standards and Technology (NIST) has finalized the first three algorithms that will form the backbone of the world's strategy to counter the potential threats of quantum computing.

Given that enterprising hackers are likely already harvesting and storing massive volumes of encrypted sensitive data for future exploitation, this is welcome news. We have the first post-quantum cryptography (PQC) algorithms to defend against the inevitable attacks on "Q-Day," when a cryptographically relevant quantum computer (CRQC) comes online.

Still, having these NIST-approved algorithms is just the first step. For the information and communications technology (ICT) industry, transitioning to a quantum-safe infrastructure is not a straightforward task; numerous challenges must be overcome. It requires a combination of engineering efforts, proactive assessment, evaluation of available technologies, and a careful approach to product development.

**The Post-Quantum Transition**

PQC algorithms are relatively new, and with no CRQC available to fully test, we cannot yet achieve 100% certainty of their success. Yet we know that any asymmetric cryptographic algorithm based on integer factorization, finite field discrete logarithms, or elliptic curve discrete logarithms will be vulnerable to attacks from a CRQC using Shor's algorithm. That means key agreement schemes (Diffie-Hellman or Elliptic Curve Diffie-Hellman), key transport (RSA encryption) mechanisms, and digital signatures must be replaced.

Conversely, symmetric-key cryptographic algorithms are generally not directly affected by quantum computing advancements and can continue to be used, with potentially straightforward increases to key size to stay ahead of quantum-boosted brute-forcing attacks.

**Hybrid Approach to Security**

The migration to PQC is unique in the history of modern digital cryptography in that neither traditional nor post-quantum algorithms are fully trusted to protect data for the required lifetimes. During the transition from traditional to post-quantum algorithms, we will need to use both algorithm types.

Defense and government institutions have already begun integrating these algorithms into the security protocols of specific applications and services due to the long-term sensitivity of their data. Private companies have also kicked off initiatives. For instance, Apple is using Kyber to create post-quantum encryption in iMessage, while Amazon is using Kyber in AWS.

Large-scale proliferation of PQC is coming, as global standards bodies, such as 3GPP and IETF, have already begun incorporating them into the security protocols of future standards releases. For instance, the IETF-designed Transport Layer Security (TLS) and Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA) — two of the most widely used protocols across 3GPP networks— will both incorporate PQC.

This kind of standardization is key for industries like telecommunications and Internet services, where hundreds of different companies are providing the different hardware, device, and software components of a network. Like any security protocol, PQC must be implemented consistently across all exposed elements in the network chain because any link that isn't quantum-safe will become the focal point of any data harvesting attack.

Over the next few years, we will see more and more PQC-enhanced products enter the market. At first, they will likely use hybrid approaches to security, using both classical and post-quantum encryption schemes, as Apple and Amazon have done. But as quantum-security technologies advance and are further tested in the market, PQC will likely replace classical asymmetric encryption methods.

Because asymmetric algorithms are largely used for secure communications between organizations or endpoints that may not have previously interacted, a significant amount of coordination in the ecosystem is needed. Such transitions are some of the most complicated in the tech industry and will require staged migrations.

**Ready for Q-Day**

PQC isn't the only way to protect against a quantum attack, as quantum threats will only increase in sophistication. It's vital to deploy a defense-in-depth strategy — one that includes physics-based solutions like preshared keys with symmetric distribution and quantum key distribution (QKD) — but PQC will be a powerful security tool.

Attention to interoperability will be key here, as crypto agility will ease the migration to pure quantum-safe algorithms in the future. Some companies are already leaning toward open source rather than proprietary code, which can help to avoid a bumpy upgrade path in future for security products. As well, this crypto agility will ensure that technologies being designed now for inclusion in next-generation/6G products will also have backward-compatibility with 5G and other earlier standards.

Now that we have the essential first algorithms to build our arsenal against quantum computing threats, the next steps for the ICT industry will be critical. They must adopt hybrid solutions now to combat harvest-now-decrypt-later attacks; embrace crypto agility, interoperability, and rigorous testing; and deploy a defense-in-depth strategy. By following this strategy, we will be well on track to ensuring our long-term security and saving the world from potential disaster when Q-Day comes.

What Communications Companies Need to Know Before Q-Day

Armed with a staggering arsenal of at least 20,000 different exploits for various Linux server misconfigurations, perfctl is everywhere, annoying, and tough to get rid of.

Source: J Poulssen via Alamy Stock Photo

A multipurpose and mysterious malware dropper has been terrorizing Linux servers worldwide for years, infecting untold thousands of victims with cryptomining and proxyjacking malware. A fresh analysis has exposed its secrets — and a vast treasure trove of tens of thousands of exploit paths for compromising its targets.

It's been some time now that individuals in the US and Russia, Germany and Indonesia, Korea, China, Spain, and most everywhere in between have been reporting cases of "perfctl" (aka perfcc) eating up all their compute power.

"We've seen blog and forum posts over the past three or four years — maybe even longer — saying, 'something is attacking me, I don't know, I'm trying to kill it,'" Aqua Nautilus chief researcher Assaf Morag recalls. "There are a lot of articles describing how you kill perfctl, but people can't kill it because it keeps hiding itself, and it's very persistent."

The malware looks for vulnerabilities and misconfigurations to exploit in order to gain initial access. To date, Aqua Nautilus reported today, the malware has likely targeted millions of Linux servers, and compromised thousands. Any Linux server connected to the Internet is in its sights, so any server that hasn't already encountered perfctl is at risk.

Related:Dark Reading News Desk Live From Black Hat USA 2024

And, Morag warns, its ambitions don't necessarily end with cryptomining and proxyjacking. Though not recorded in his report, Morag has observed the malware dropping TruffleHog, a legitimate penetration testing tool designed to snuff out hardcoded secrets in source code.

"So imagine: They're earning money on the side \[by cryptomining and proxyjacking\], but also stealing secrets and maybe selling them in the cyber underground — selling access to servers that are related to big companies," he posits.

**Every Misconfiguration in the Book**

The volume and variety of potential server misconfigurations that perfctl is capable of identifying and exploiting is vast.

By tracking its infections, researchers identified three Web servers belonging to the threat actor: two that were previously compromised in prior attacks, and a third likely set up and owned by the threat actor. One of the compromised servers was used as the primary base for malware deployment. The other compromised server contained a much more interesting find: a list of potential avenues to directory traversal, nearly 20,000 entries long.

The list contained more than 12,000 known server misconfigurations, nearly 2,000 paths towards nabbing unauthorized credentials, tokens, and keys, more than 1,000 techniques for unauthorized login, and dozens of possible misconfigurations in different applications (68, for example, associated just with Apache RocketMQ, the open source distributed messaging and streaming platform). Citing just a few examples, Morag explains that "if you have an HTTP server, maybe you expose a template. In Kubernetes, by mistake, you could expose secrets, or roles. Or even a weak password can be a misconfiguration."

Alongside this fuzzing list on the compromised server were follow-on files containing exploits for the various kinds of documented misconfigurations.

Besides misconfigurations, perfctl is also capable of gaining initial access to a server via various bugs, such as CVE-2023-33246, a remote command execution (RCE) vulnerability in Apache RocketMQ. CVE-2023-33246 earned a "critical" 9.8 out of 10 score on the Common Vulnerability Scoring System (CVSS) last year.

**How perfctl Hides Loud Activity**

Cryptomining and proxyjacking are loud by nature. Whether it be third-party proxyware or the XMRig Monero miner, the programs that perfctl drops onto a compromised server will exhaust its CPU resources. And yet, perfctl itself is not easy to spot or excise, thanks to its layers of sophisticated stealth and persistence mechanisms.

For example, to facilitate stealthy communication, the program drops a backdoor and listens for communications via Tor. And to avoid detection and obscure evidence of its presence, it uses process masquerading, copying itself to various locations under names that map to legitimate system processes.

The very name its authors gave to it, "perfctl," is evidence of the same sort of tactic: "perf" is a Linux monitoring tool, and "ctl" is commonly used as a suffix for command line tools which control system components or services. The legitimate-looking name of the malware, then, allows it to more easily blend in with typical processes.

And then, after executing, perfctl deletes its binary but continues to run as a service behind the scenes.

To further hide its presence and malicious activities from security software and researcher scrutiny, it deploys a few Linux utilities repurposed into user-level rootkits, as well as one kernel-level rootkit. The kernel rootkit is especially powerful, hooking into various system functions to modify their functionality, effectively manipulating network traffic, undermining Pluggable Authentication Modules (PAM), establishing persistence even after primary payloads are detected and removed, or stealthily exfiltrating data.

And when a user logs in to the compromised server, perfctl instantly halts its noisiest behaviors, laying low until the user logs off and the coast is clear.

In short, "it's a powerful tool," Morag says. "You can decide to erase data, to steal data, to buy cryptocurrency, to do proxyjacking — it's up to the attacker."

**Mitigation for perfctl & Other Fileless Malware**

Those running Linux servers should take immediate steps to protect their environments, researchers warned. Aqua recommends the following mitigations for perfctl and similar threats:

*   Patch vulnerabilities: Ensure that all vulnerabilities are patched. Particularly internet facing applications such as RocketMQ servers and CVE-2021-4043 (Polkit). Keep all software and system libraries up to date.
    
*   Restrict file execution: Set noexec on /tmp, /dev/shm and other writable directories to prevent malware from executing binaries directly from these locations.
    
*   Disable unused services: Disable any services that aren’t required, particularly those that may expose the system to external attackers, such as HTTP services.
    
*   Implement strict privilege management: Restrict root access to critical files and directories. Use role-based access control (RBAC) to limit what users and processes can access or modify.
    
*   Network segmentation: Isolate critical servers from the internet or use firewalls to restrict outbound communication, especially TOR traffic or connections to cryptomining pools.
    
*   Deploy runtime protection: Use advanced anti-malware and behavioral detection tools that can detect rootkits, cryptominers, and fileless malware like perfctl.

A large-scale fraud campaign leveraged fake trading apps published on the Apple App Store and Google Play Store, as well as phishing sites, to defraud victims, per findings from Group-IB.

The campaign is part of a consumer investment fraud scheme that's also widely known as pig butchering, in which prospective victims are lured into making investments in cryptocurrency or other financial instruments after gaining their trust under the guise of a romantic relationship or an investment advisor.

Such manipulative and social engineering operations often end with the victims losing their funds, and in some cases, extracting even more money from them by requesting various fees and other payments.

The Singapore-headquartered company said the campaign has a global reach, with victims reported across Asia-Pacific, European, Middle East and Africa. The bogus apps, built using the UniApp Framework, have been classified under the moniker **UniShadowTrade**.

The activity cluster is said to have been active since at least mid-2023, luring victims with malicious apps with the promise of quick financial gain. A noteworthy aspect of the threat is that one of the apps managed to even get past Apple's App Store review process, thus lending it an illusion of legitimacy and trust.

The app in question, SBI-INT, is no longer available for download from the app marketplace, but it masqueraded as software for "commonly used algebraic mathematical formulas and 3D graphics volume area calculation."

It's believed that the cybercriminals accomplished this by means of a check that included the app's source code that checked if the current date and time is earlier than July 22, 2024, 00:00:00, and if so, launched a fake screen with formulae and graphics.

But once it was taken down weeks after it was published, the threat actors behind the operation are said to have pivoted to distributing the app, for both Android and iOS, via phishing websites.

"For iOS users, pressing the download button triggers the download of a .plist file, prompting iOS to ask for permission to install the application," Group-IB researcher Andrey Polovinkin said.

"However, after the download is complete, the application cannot be launched immediately. The victim is then instructed by the cybercriminals to manually trust the Enterprise developer profile. Once this step is completed, the fraudulent application becomes operational."

Users who end up installing the app and opening it are greeted with a login page, requiring users to provide their phone number and password. The registration process involves entering an invitation code in the app, suggesting that the attackers are targeting specific individuals to pull off the scam.

A successful registration triggers a six-step attack process wherein the victims are urged to provide identity documents as proof, personal information, and current job details, after which they are asked to agree to the service's terms and conditions in order to make the investments.

Once the deposit has been made, the cybercriminals send further instructions on which financial instrument to invest in and often guarantee that they will yield high returns, thereby deceiving users into investing more and more money. To maintain the ruse, the app is rigged to display their investments as making gains.

Trouble starts when the victim attempts to withdraw the funds, at which point they are asked to pay additional fees to recover their principal investments and purported gains. In reality, the funds are stolen and diverted to accounts under the attackers' control.

Another novel tactic adopted by the malware authors is the use of an embedded configuration that includes specifics about the URL that hosts the login page and other aspects of the purported trading application launched within the app.

This configuration information is hosted in a URL associated with a legitimate service called TermsFeed that offers compliance software for generating privacy policies, terms and conditions, and cookie consent banners.

"The first discovered application, distributed through the Apple App Store, functions as a downloader, merely retrieving and displaying a web-app URL," Polovinkin said. "In contrast, the second application, downloaded from phishing websites, already contains the web-app within its assets."

This, per Group-IB, is a deliberate approach taken by the threat actors to minimize the chances of detection and avoid raising red flags when the app is distributed through the App Store.

Furthermore, the cybersecurity firm said it also discovered one of the fake stock investment scam apps on the Google Play Store that went by the name FINANS INSIGHTS (com.finans.insights). Another app linked to the same developer, Ueaida Wabi, is FINANS TRADER6 (com.finans.trader)

While both Android apps are not present in the Play Store, statistics from Sensor Tower show that they were downloaded less than 5,000 times. Japan, South Korea, and Cambodia were the top three countries served by FINANS INSIGHTS, whereas Thailand, Japan, and Cyprus were the primary regions where FINANS TRADER6 was available.

"Cybercriminals continue to use trusted platforms such as the Apple Store or Google Play to distribute malware disguised as legitimate applications, exploiting users' trust in secure ecosystems," Polovinkin said.

"Victims are lured in with the promise of easy financial gains, only to find that they are unable to withdraw funds after making significant investments. The use of web-based applications further conceals the malicious activity and makes detection more difficult."

Fake Trading Apps Target Victims Globally via Apple App Store and Google Play

Pig Butchering scam targets crypto users with fake trading apps on Apple and Google Play Stores. Disguised as…

Pig Butchering scam targets crypto users with fake trading apps on Apple and Google Play Stores. Disguised as legitimate platforms, these apps defraud investors, bypassing store checks and exploiting unsuspecting users globally.

A fraud campaign targeting **Apple iOS and Android users** has been discovered by GroupIB, involving fake trading apps. These apps, found on Apple’s App Store and Google Play, and on phishing sites, are part of a Pig Butchering scam targeting cryptocurrency investors in Asia-Pacific, Middle East & Africa, and European regions.

Group-IB’s Threat Intelligence, and Fraud Protection analysts first discovered these fake mobile applications in May 2024 and have been investigating the campaign ever since.

According to their **report** shared with Hackread.com ahead of publishing on Wednesday, these applications were developed for Android using a single cross-platform framework. One was distributed through the Google Play store, while another targeted iOS devices.

What’s worse, unlike traditional mobile trojans, these applications had no typical malicious features and cybercriminals have created a facade of a legitimate trading platform to defraud victims.

The fraudulent apps check the current date and time to bypass Apple’s App Store checks, launching a fake activity with mathematical formulas and graphics if it is earlier than 22 July 2024, 00:00:00. Android samples were designed to display a fraudulent trading application hosted on the api.fxbrokerscc domain, part of a larger fraudulent infrastructure.

According to researchers, these fake trading apps and downloader apps mimic legitimate platforms and may include features like account settings, transaction history, and stock information. Downloader apps, found in the Apple App Store or distributed through phishing websites, prompt victims to install the fraudulent app.

The malware family used in the pig butchering scam is **UniShadowTrade**, classified under the UniApp Framework. This name is given by Group-IB analysts to categorize the fraudulent applications involved in the scam. For your information, the UniApp framework enables developers to create cross-platform applications with a single codebase, making it easier for scammers to develop and distribute malware.

****What Exactly is Pig Butchering?****

For your information, **Pig butchering** is a notorious digital scam that involves a meticulous process of grooming victims, building trust, and ultimately defrauding them of their money.

This particular campaign follows a specific pattern: target identification through social media, grooming and trust-building through social engineering techniques, offering a seemingly lucrative investment opportunity in cryptocurrency or other investments, encouraging a small initial investment, and building confidence through small profits.

Scammers pressure victims into making large investments, transfer funds they cannot withdraw, and disappear. This process continues until the victim is unable to withdraw the funds, causing significant financial loss and affecting their financial stability.

Nevertheless, scams Pig butchering can have devastating consequences for victims. Understanding scammers’ tactics and taking proactive measures can reduce the risk of falling victim to such fraud.

****Alert for Android and iOS users****

It is a fact that Google, which owns Android, and Apple, which owns the iOS App Store, try their best to keep the marketplace safe from malware and other cybersecurity threats. Despite constant monitoring, cybercriminals often slip into these stores with malicious apps, draining the bank accounts and crypto wallets of unsuspecting users.

Just last week, **Google approved** a crypto drainer app on the Play Store that stole over $70,000 from Android users. On the other hand, **in February 2024**, Apple approved a fake LastPass Password Manager app on its iOS App Store. The same month, Apple approved a **fake Rabby Wallet app** that stole millions from unsuspecting users.

Therefore, be extra careful when downloading an app from any of these stores. Check their reviews, search for the official app on Google, find their social media platforms, and confirm whether the app advertised on app stores is legitimate or not.

COMMENTARY

The global rise of increasingly sophisticated cybercrimes creates daily challenges for the cybersecurity industry, as security professionals grapple with new and evolving attacks, complex IT architecture, and the integration of artificial intelligence (AI) into nefarious actors' tactics, techniques, and procedures (TTPs). As a result, cybersecurity practitioners feel a sense of urgency to stay at the forefront of technological advances to defend against a growing arsenal of exploits.

In this environment, a methodical approach to the intentional use of AI for cybersecurity protocols will help avoid falling prey to the hype and myths of groupthink, such as these five myths of AI and cybersecurity: 

**1\. You'll fall behind if AI isn't your primary solution for cybersecurity.**

While AI can enhance cybersecurity tasks by analyzing large volumes of data to recognize nefarious identifying patterns, it can also be susceptible to false positives and negatives, be trained on bad data, or act in unexpected ways. Many common cyber threats can still be effectively mitigated through basic security practices like strong passwords, regular patching, and employee awareness about social engineering. Incorporating AI into security solutions is not a license to abandon proven tools and replace established best practices. Sophisticated attackers will find ways to evade AI-based detection, so adopting AI cannot be the only solution for security and defense. Time-tested security practices like organizational culture, leadership commitment, and employee training are still critical fundamentals of a robust organizational risk management practice. 

**2\. Threat actors are using AI, which will lead to an exponential increase in cyberattacks.**

AI is undoubtedly a powerful tool that can be used for both good and bad — it's not a guaranteed game-changer for threat actors. The cybersecurity landscape is a dynamic battleground, and the interplay between AI-powered attacks and defenses is complex. AI may increase the speed and sophistication of certain attacks, such as better phishing attempts; however, it has not fundamentally changed the attack vectors or the attack surface within organizations. A mature security posture using foundational defensive practices continues to be a sound approach to reducing risk and thwarting attacks. 

**3\. AI-powered tools are better, and every tool needs an AI feature.**

AI-aided tools can provide powerful additions to a defensive infrastructure with quicker, more comprehensive data discovery. Left unchecked, AI is capable of producing sometimes comical but altogether bad results, such as the Google Overview suggestion of adding glue to homemade pizza sauce, or the McDonald's AI drive-through putting bacon on ice cream. In cybersecurity, erroneous results have serious consequences, including loss of trust, excessive costs, and endangering human safety. The potential benefit of any AI-powered resource must be balanced against the potential cost of error. The safest use of AI is within a layered defense model, which allows for verification and redundancy in protective solutions. 

**4\. You can only combat AI with AI.**

AI is a valuable tool in the cybersecurity quiver, but it's not impenetrable. Like any other defensive technique, attackers can exploit vulnerabilities in AI models or develop exploits to bypass AI defenses. Combating AI threats requires a multilayered approach that combines AI with human expertise, traditional security measures, and a strong focus on prevention, detection, and response. Using AI to combat AI may also raise ethical and legal concerns, particularly around issues like autonomous decision-making, accountability, and potential for misuse. These concerns must be carefully considered before implementation, to ensure responsible, ethical use of AI in cybersecurity. By leveraging the strengths of both humans and AI, organizations can build a more resilient and effective cybersecurity posture. 

**5\. AI is going to replace your job.**

Companies who are hiring fewer entry-level people for cybersecurity roles are not doing so because AI has eliminated those jobs; rather, they are limited by shrinking budgets and a need to hire people who can make an immediate impact when they come onboard. AI excels at automating repetitive tasks, analyzing vast amounts of data and identifying patterns, but human intuition and judgment is still needed to interpret those insights, make critical decisions, and adapt strategies to combat evolving threats. At its best, AI allows humans to focus on creative and strategic thinking to deliver complex problem-solving. The prominence of AI has created new jobs like AI engineers and AI ethicists to manage AI systems. AI-related roles, along with roles in cybersecurity, will continue to emerge and evolve. AI won't replace people, but people who know how to work with AI may replace people who don't. 

Effective cybersecurity requires a multilayered approach that combines technology, processes, and people. Solely relying on AI for cybersecurity can create a false sense of security, and AI-based cybersecurity solutions can be costly and complex. While AI is transforming the workforce, it's unlikely to lead to widespread job displacement. Instead, it likely will change the nature of work and require adaptation and development of new skills.

Progressive companies will see the value of investing in training programs and implementing policies that support workforce transition. Organizations looking to maximize their security posture with enhanced value, productivity, creativity, and innovation will find AI a valuable complement to existing people, systems, and processes.
