BambooToken is an emerging multiplatform malware family active since at least February 2023, utilizing the Message Queueing and Telemetry Transport (MQTT) protocol for covert command and control operations. The campaign targets Windows and Linux systems across Asia and South America, with infections observed on backend servers for mobile applications, legal and financial services, software companies, hotels, and GitLab instances. The malware leverages sideloading techniques through Tendyron's OnKey authentication software, commonly used in Chinese banking and government networks. Analysis reveals extensive host enumeration capabilities, plugins for antivirus detection, and potential keylogging and clipboard theft functions. Infrastructure analysis shows C2 domains ranking in Cloudflare's top 500,000, indicating widespread infections. The actor demonstrates sophisticated operational security, using MQTT's publish-subscribe architecture to hide infrastructure and employing Cloudflare proxies for additional o...

MacSync Stealer is a macOS information stealer and remote-access stager delivered through ClickFix social engineering and malvertising campaigns. Operating under a malware-as-a-service model, it employs sophisticated evasion techniques including process daemonization, single-byte XOR obfuscation, and in-memory AppleScript execution to bypass Apple Gatekeeper, XProtect, and EDR solutions. The malware exfiltrates credentials, browser data, cryptocurrency wallets, and SSH keys through fault-tolerant 10MB chunked uploads to command-and-control infrastructure. MacSync targets professionals in software engineering, cryptocurrency, fintech, and corporate environments across North America, Europe, and Asia-Pacific regions, with campaigns impersonating legitimate services like Google Meet, Claude AI, Docker, and TradingView to trick victims into executing malicious Terminal commands.

A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service (DoS) by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryError (OOM) and subsequent process termination. This vulnerability allows an attacker to disrupt the availability of the service.

Mirage2FA is an active phishing-as-a-service toolkit built to steal Microsoft 365 credentials and authenticated sessions through Adversary-in-the-Middle attacks. Analysis shows 63.7% of identified victims are in the US, with Technology, Manufacturing, and Education among the most targeted industries. The operation generated thousands of compromise events between 2024 and 2026, including stolen session cookies, passwords, and SSO access. Once a Microsoft 365 session is hijacked, attackers gain access to corporate email, sensitive data, and trusted business accounts. The toolkit uses browser-based delivery through .htm, .xhtml, and .svg stagers, QR codes, JavaScript obfuscation, and WebSocket-based AiTM activity. Of 9,426 unique targeted email addresses, 4,532 were potentially compromised, representing approximately 48% success rate.
