Summary

Hide ▲

The Vietnamese threat actor BatShadow is using a new Go-based malware called Vampire Bot to target job seekers and digital marketing professionals. The attack involves social engineering tactics where the group poses as recruiters and distributes malicious files disguised as job descriptions and corporate documents. The malware is capable of profiling infected hosts, stealing information, capturing screenshots, and maintaining communication with a command-and-control server. The infection chain begins with ZIP archives containing decoy PDFs and malicious shortcut or executable files. The malware is delivered through a multi-stage process involving PowerShell scripts, fake error messages, and remote desktop software to establish persistent access. The actors have been active for at least a year and have previously used similar tactics to deploy other malware families. The malware captures screenshots at configurable intervals, compresses them into WEBP format, and exfiltrates them over encrypted channels. The malware is written in Go and continuously checks in with its command and control (C2) server for new commands and additional payloads. The targets in BatShadow's latest campaign are individuals in transition or with high online visibility, such as job seekers and digital marketing professionals. The malware hides in core system folders and uses additional tags and attributes to conceal itself.

Malicious npm package 'fezbox' uses QR codes to deliver cookie-stealing malware

A malicious npm package named 'fezbox' was discovered using QR codes to fetch and execute cookie-stealing malware. The package, disguised as a utility library, was downloaded at least 327 times before being removed from the npm registry. The malware targets user credentials and employs steganographic techniques to evade detection. The package was found to fetch a JPG image containing a QR code, which then executes a second-stage payload. The QR code is designed to be unusually dense and difficult to read with standard phone cameras, making it harder to detect. The package was published by a Chinese-speaking attacker using the alias 'janedu' and included multiple layers of obfuscation to evade detection. The malware specifically targets cookies to steal usernames and passwords, sending the stolen information via an HTTPS POST request to a command-and-control server. The package was removed and flagged as malware posing a supply-chain risk. The attacker's activity status on the npm registry remains unclear. The package's ReadMe mentioned a QR Code Module, making its existence seem legitimate. The package used reversed strings as an anti-analysis technique. The payload could read a web cookie and extract the username and password if both were present.

Global Phishing Campaign Installs Multiple RATs via JavaScript Droppers

A rapidly spreading phishing campaign is targeting Windows users worldwide, stealing credentials and deploying various remote access trojans (RATs) using malicious JavaScript files. The campaign affects multiple sectors, including manufacturing, technology, healthcare, construction, and retail/hospitality. The attackers use personalized phishing pages and socially engineered scenarios to lure victims into downloading the malware. The campaign involves multiple stages, including an initial obfuscated script, a spoofed site, and the deployment of RATs such as PureHVNC, DCRat, and Babylon RAT. The attackers employ sophisticated techniques to evade detection and maintain long-term access to compromised networks. The campaign has been observed in countries including Austria, Belarus, Canada, Egypt, India, and Pakistan. The phishing emails use themes related to voicemail messages and purchases to deceive recipients into clicking on malicious links. The initial payload is a ZIP archive containing an obfuscated JavaScript file that acts as a dropper for UpCrypter, which functions as a conduit for various RATs. The malware uses steganography to embed the final payload within a harmless-looking image and includes anti-analysis and anti-virtual machine checks to evade detection. The malware is executed without writing to the file system, minimizing forensic traces. The campaign is part of a larger trend where threat actors abuse legitimate services for phishing attacks. A new campaign impersonates Ukrainian government agencies to deliver CountLoader, which drops Amatera Stealer and PureMiner. The phishing emails contain malicious SVG files designed to trick recipients into opening harmful attachments. The SVG files initiate the download of a password-protected ZIP archive containing a CHM file, which activates CountLoader. CountLoader drops various payloads, including Cobalt Strike, AdaptixC2, and PureHVNC RAT, and in this case, Amatera Stealer and PureMiner. Amatera Stealer gathers system information, collects files, and harvests data from various applications and browsers. A Vietnamese-speaking threat group uses phishing emails with copyright infringement notice themes to deploy PXA Stealer, which evolves into PureRAT. PureRAT is a modular, professionally developed backdoor that gives attackers complete control over a compromised host. The campaign demonstrates a progression from simple phishing lures to multi-layered infection sequences involving defense evasion and credential theft. The attack chain begins with a ZIP archive containing a legitimate PDF reader executable and a malicious DLL, using DLL sideloading to execute the next payload. The malware employs multiple stages of obfuscation, including Base64 encoding, steganography, and anti-analysis techniques to evade detection. The campaign uses a combination of Python scripts and .NET executables to achieve its objectives, demonstrating a progression from simple phishing lures to multi-layered infection sequences. The final payload, PureRAT, is a modular, professionally developed backdoor that provides complete control over a compromised host. The threat actor uses Telegram bot descriptions and URL shorteners to dynamically fetch and execute the next payload, allowing for flexible updates to the attack chain. The malware includes defense evasion techniques such as AMSI patching and ETW unhooking to avoid detection by security tools. The campaign is attributed to a Vietnamese-speaking threat group associated with the PXA Stealer malware family, using infrastructure traced to Vietnam. The threat actor demonstrates proficiency in multiple languages and techniques, including Python bytecode loaders, WMI enumeration, .NET process hollowing, and reflective DLL loading. The pivot from a custom-coded stealer to a commercial RAT like PureRAT lowers the barrier to entry for the attacker, providing access to a stable, feature-rich toolkit.

UNC5518 Access-as-a-Service Campaign via ClickFix and Fake CAPTCHA Pages

The FileFix social engineering attack, a variant of the ClickFix family, impersonates Meta account suspension warnings to trick users into installing the StealC infostealer malware. The campaign has evolved over two weeks with different payloads, domains, and lures, indicating an attacker testing and adapting their infrastructure. The FileFix technique, created by red team researcher mr. d0x, uses the address bar in File Explorer to execute malicious commands. The campaign employs steganography to hide a second-stage PowerShell script and encrypted executables inside a JPG image, which is believed to be AI-generated. The StealC malware targets credentials from various applications, cryptocurrency wallets, and cloud services, and can take screenshots of the active desktop. The FileFix attack uses a multilingual phishing site to trick users into executing a malicious command via the File Explorer address bar. The attack leverages Bitbucket to host the malicious components, abusing a legitimate source code hosting platform to bypass detection. The attack involves a multi-stage PowerShell script that downloads an image, decodes it into the next-stage payload, and runs a Go-based loader to launch StealC. The attack uses advanced obfuscation techniques, including junk code and fragmentation, to hinder analysis efforts. The FileFix attack is more likely to be detected by security products due to the payload being executed by the web browser used by the victim. The FileFix attack demonstrates significant investment in tradecraft, with carefully engineered phishing infrastructure, payload delivery, and supporting elements to maximize evasion and impact. The MetaStealer attack, a variant of the ClickFix family, uses a fake Cloudflare Turnstile lure and an MSI package disguised as a PDF to deploy the MetaStealer infostealer malware. The attack involves a multi-stage infection chain that includes a DLL sideloading technique using a legitimate SentinelOne executable. The MetaStealer attack targets crypto wallets and other sensitive information, using a combination of social engineering and technical evasion techniques to deploy malware. Previously, threat actors tracked as UNC5518 leveraged a social engineering tactic called ClickFix to deploy the CORNFLAKE.V3 backdoor. The campaign used fake CAPTCHA pages to trick users into executing malicious PowerShell scripts, providing initial access to systems. This access was then monetized by other threat groups, including UNC5774 and UNC4108, which deployed additional payloads. The attack began with users interacting with compromised search results or malicious ads, leading them to fake CAPTCHA pages. Users were then tricked into running a malicious PowerShell command, which downloaded and executed the CORNFLAKE.V3 backdoor. This backdoor supported various payload types and could collect system information, which was transmitted via Cloudflare tunnels to evade detection. CORNFLAKE.V3 is an updated version of CORNFLAKE.V2, featuring host persistence and additional payload support. The campaign also involved the deployment of WINDYTWIST.SEA, a backdoor that supports lateral movement within infected networks.
