A sophisticated infection chain has been discovered that installs CastleRAT malware without leaving traces on disk. The attack uniquely abuses the Deno runtime as a malicious framework, combining social engineering, steganography, and in-memory execution to evade detection. The process involves tricking users into executing a command, installing Deno, running obfuscated JavaScript, and decoding a payload hidden in a JPEG image. CastleRAT then gains total control, performing host fingerprinting, keylogging, clipboard hijacking, digital identity theft, and audio/video surveillance. This campaign demonstrates the evolution of malware towards invisibility and the need for advanced endpoint behavioral monitoring to detect such threats.
BlackSanta is a malware module designed to disable endpoint detection and response (EDR) and antivirus (AV) solutions before executing its primary malicious payload. By killing these security defenses first, it increases the likelihood of successful infection and persistence on targeted systems. Although no known exploits are currently reported in the wild, the malware’s capability to neutralize security tools poses a significant risk. The threat is rated medium severity due to its potential impact on system integrity and confidentiality, but it requires initial access to the target environment. Organizations should prioritize detection of unusual process terminations and implement robust endpoint protection strategies. Countries with high adoption of EDR/AV solutions and critical infrastructure are more likely to be targeted. Immediate mitigation involves hardening endpoint security, monitoring for suspicious process behavior, and applying strict access controls to limit malware execution opportunities.
A new phishing technique abusing Microsoft's OAuth Device Code flow is on the rise, with over 180 phishing URLs detected in a week. This method shifts from credential theft to token-based account takeover, making detection more challenging. Attackers initiate a device authorization process, tricking victims into approving it on legitimate Microsoft pages. The attack uses encrypted HTTPS traffic and legitimate authentication flows, bypassing traditional phishing indicators. Victims unknowingly grant attackers access to their Microsoft 365 accounts through OAuth tokens. This poses a critical risk as it allows immediate access to corporate data and resources, potentially leading to business email compromise and persistent access through refresh tokens.
Key Points Iran-linked actors are increasingly engaging with the cyber crime ecosystem. Their activity suggests a growing reliance on criminal tools, services, and operational models in support of state objectives. Iranian actors have long used cyber crime and hacktivism as cover for destructive activity, but the trend now suggests direct engagement with the criminal ecosystem.

A deceptive website impersonating CleanMyMac tricks users into installing SHub Stealer, a sophisticated macOS malware. The malware steals sensitive data, including passwords, browser data, cryptocurrency wallets, and Telegram sessions. It can also modify wallet apps to steal recovery phrases. The attack begins with users pasting a command into Terminal, which downloads and executes a malicious script. The malware performs extensive data collection from various browsers and wallet applications, and installs persistent backdoors in certain crypto wallet apps. SHub Stealer is part of a growing family of AppleScript-based macOS infostealers, demonstrating increasing sophistication in targeting Mac users.
A new attack technique called InstallFix targets users by cloning popular developer tool installation pages and presenting malicious install commands. Attackers distribute these fake pages through Google Ads, exploiting users' trust in familiar 'curl to bash' installation methods. The campaign specifically targets Claude Code users, delivering the Amatera Stealer malware. This technique bypasses email security controls and exploits the growing trend of non-technical users adopting developer tools. The attack leverages legitimate hosting services and is part of a broader trend targeting AI-related tools. The payload uses staged execution and various evasion techniques to avoid detection.
