Recorded Future's Insikt Group has released a report detailing the discovery of two new malware families, TerraStealerV2 and TerraLogger, both linked to the notorious Golden Chickens threat actor, also known as Venom Spider. Golden Chickens is a financially motivated group known for providing a Malware-as-a-Service (MaaS) platform, offering cybercriminals a suite of malicious tools. The newly identified malware strains add to their existing arsenal, which includes tools like VenomLNK, TerraLoader, and TerraCrypt, which have been implicated in past attacks against major organizations. The report, published on May 1, 2025, highlights the evolving tactics of this sophisticated threat actor.
TerraStealerV2 is designed to steal browser credentials, target cryptocurrency wallets, and pilfer browser extensions. This stealer malware is delivered through various file types, including LNK, MSI, DLL, and EXE files, and utilizes legitimate Windows tools like regsvr32.exe and mshta.exe to bypass endpoint detection. While TerraStealerV2 lacks the ability to decrypt credentials protected by Chrome’s Application Bound Encryption (ABE), a security measure introduced in mid-2024, it can still exfiltrate unprotected data. It copies cryptocurrency wallet directories and uploads them to Telegram bots and wetransfers[.]io, a lookalike domain hosted behind Cloudflare, showcasing the malware's data theft capabilities. TerraLogger represents the first keylogging capability developed by Golden Chickens. This standalone keylogger records keystrokes locally using a low-level keyboard hook and stores them in plaintext files within the C:\ProgramData directory. While TerraLogger currently lacks command-and-control or data exfiltration logic, its modular design suggests it is either under development or intended to be used in conjunction with other components of the Golden Chickens toolkit. Experts suggest the group continues to refine its delivery methods by combining VenomLNK attacks with Windows-native tools, indicating a persistent effort to evolve and enhance their malicious operations.

A new variant of the Lumma Stealer malware has been identified, showing significant advancements in its stealth and persistence. Researchers at the Trellix Advanced Research Center analyzed the new variant, discovering features such as code flow obfuscation and dynamic API resolution that help it evade detection. Lumma Stealer, originally introduced in 2022, has rapidly evolved and poses a serious threat to personal and organizational data by targeting sensitive information stored on infected systems.
Lumma Stealer, also known as LummaC2, has gained popularity in underground forums with over a thousand active subscribers as of March 2025. The malware uses deceptive methods such as fake CAPTCHA pages, mimicking Google reCAPTCHA or Cloudflare challenges, to trick users into executing malicious commands. These fraudulent pages are often hosted on compromised websites offering pirated content or cryptocurrency services, enticing unsuspecting users to initiate the infection chain. The malware's infection chain is complex and difficult to detect. It involves downloading a .zip file, extracting the malware, and establishing persistence through the Windows Registry's Run key. More advanced attacks hide the malware within seemingly harmless .mp3 or .png files, triggered via the mshta.exe HTML application engine, deploying layers of encryption, anti-debugging techniques, and detection evasion mechanisms. The stealer targets sensitive data, including cryptocurrency wallet credentials, 2FA codes, browser-stored passwords, and financial information, which it transmits to attacker-controlled domains.

A new wave of Android malware campaigns are exploiting Microsoft’s .NET MAUI framework to target users, particularly in India and China. Cybersecurity researchers at McAfee Labs have identified these malicious applications, which disguise themselves as legitimate services like banking and social media apps, to steal sensitive user information. These fake apps, collectively codenamed FakeApp, are not distributed through official channels like Google Play, but rather through bogus links sent via messaging apps and unofficial app stores. .NET MAUI, designed as a cross-platform development framework, allows these threats to conceal malicious code, making them difficult to detect by traditional antivirus solutions.
Researchers have found that the malware's core functionalities are written entirely in C# and stored as binary large objects, evading detection methods that typically analyze DEX files or native libraries. For instance, a fraudulent banking app impersonates IndusInd Bank, targeting Indian users by prompting them to enter personal and financial details, which are then sent to the attacker's command-and-control server. Another instance involves a fake social networking service app aimed at Chinese-speaking users, employing multi-stage dynamic loading to decrypt and execute its payload in separate stages, further complicating analysis and disrupting security tools.

Attackers are exploiting user familiarity with CAPTCHAs to distribute the Lumma Stealer RAT (Remote Access Trojan) via malicious PowerShell commands, according to recent findings. These campaigns involve tricking users into running PowerShell commands that ultimately install the Lumma Stealer. Attackers direct potential victims to attacker-controlled sites and prompt them to complete fake authentication challenges. These challenges often involve directing potential victims to malicious websites where they are prompted to complete verification steps, but instead of a CAPTCHA, it instructs them to press Windows + R and run a PowerShell command—under the false pretense of running “Windows Defender.”
These attacks leverage weaponized CAPTCHAs, with users being directed to malicious websites where they are prompted to complete verification steps. Upon completing these steps, users inadvertently copy and run PowerShell scripts that download and install malware, such as the Lumma Stealer. This allows the attackers to steal sensitive data like cryptocurrency wallets. The exploitation involves fake Cloudflare verification prompts, which lead users to execute malicious PowerShell commands to install the LummaStealer Trojan through infected WordPress sites, posing a significant threat.
