A new tech support scam campaign exploits Microsoft's trusted brand to deceive users. It starts with phishing emails promising payments, leading victims to fake CAPTCHA challenges. After completion, users are redirected to a browser-locked landing page mimicking ransomware, with multiple pop-ups resembling Microsoft security alerts. These pop-ups urge victims to call a fraudulent support number, enabling phone-based social engineering. The scam combines browser manipulation, phishing, and social engineering to potentially gain system access. No direct malware or exploits are involved, but the psychological manipulation can lead to financial loss or unauthorized access. The campaign underscores the risks of trusting familiar branding without verification and highlights the need for user awareness and layered defenses. Indicators include multiple malicious URLs and domains used in the campaign. The threat is medium severity due to its social engineering nature and potential impact on confidentiality and integrity.

A detailed analysis of a malicious PDF editor application called AppSuite PDF Editor reveals it to be a sophisticated backdoor. The software, masquerading as a legitimate productivity tool, is distributed through high-ranking websites. Once installed, it creates scheduled tasks and establishes persistence mechanisms. The backdoor communicates with command and control servers, allowing threat actors to execute arbitrary commands, exfiltrate data, and manipulate browser settings. It specifically targets Chromium-based browsers and other applications like Wave browser, Shift browser, and OneLaunch. The malware employs advanced techniques such as AES encryption, custom obfuscation, and event logging to evade detection. The analysis concludes that AppSuite PDF Editor is definitively malicious and should be classified as a trojan horse with backdoor capabilities.
