GhostPoster: Steganography Malware

GhostPoster Attacks Hide Malicious JavaScript in Firefox Addon Logos

Ravi Jain
GhostPoster that compromised over 50,000 Firefox browsers by concealing malicious JavaScript code within the logo images of popular extensions using a technique called steganography. This threat avoids detection through delayed activation (48 hours) and probabilistic payload delivery, making it extremely difficult for standard security tools to identify. Once active, the malware performs financial fraud by hijacking affiliate links, injects pervasive tracking code onto every website visited, and weakens browser defenses by stripping security headers. The text concludes with an urgent call for users to manually remove the compromised extensions and for businesses to adopt proactive extension whitelisting and specialized browser security audits to defend against such complex, evasive threats. ...

Glassworm Malware Strikes Again: Third Wave Targets Visual Studio Code Developers

Ravi Jain
Glassworm malware campaign, a sophisticated supply chain attack that specifically targets developers utilizing the Visual Studio Code extension marketplaces, including OpenVSX and Microsoft. This latest wave of malware evades platform security by employing advanced obfuscation techniques, notably using invisible Unicode characters and pushing malicious code through updates after initial approval. Once active, Glassworm’s primary function is credential theft, harvesting authentication tokens for GitHub, npm, and other developer accounts, while also targeting dozens of cryptocurrency wallets. The malware further establishes persistent access by deploying SOCKS proxies and HVNC (Hidden Virtual Network Computing) clients, granting attackers undetected remote control over the compromised development environment. Utilizing the urgency of this threat, the text concludes with a promotional section from Technijian, a managed IT services provider, marketing its specialized cybersecurity, security training, and comprehensive defense strategies to businesses in Southern California. ...

New ClickFix Attack Targeting Windows and macOS Users to Deploy Infostealer Malware

Ravi Jain
ClickFix, a sophisticated social engineering attack active in 2025 that deploys infostealer malware against both Windows and macOS users. This technique is highly effective because it bypasses traditional security tools by manipulating users into executing malicious fileless commands disguised as legitimate troubleshooting steps, leveraging trusted platforms like Google services to maintain credibility. The text explains the distinct attack vectors for Windows (distributing ACR stealer via fake software archives) and macOS (using a fake Cloudflare prompt to execute the Odyssey stealer via the Terminal), emphasizing the challenges security solutions face with this memory-resident malware. Finally, the document concludes with advice on recognizing and avoiding ClickFix, along with a pitch from Technijian, an Orange County-based Managed IT Services provider, detailing their services for helping organizations defend against such advanced cross-platform social engineering attacks. ...
