Large-Scale Phishing Attacks Targeting Microsoft Enterprise Email Services.

Security researchers from ThreatLabz have uncovered a new strain of a large-scale phishing campaign using adversary-in-the-middle (AiTM) techniques along with several evasion tactics.

According to an advisory published by the company on Tuesday, similar AiTM phishing techniques were used in a separate phishing campaign described by Microsoft last month.

Now, ThreatLabz revealed that using intelligence gathered from the Zscaler cloud, it observed an increase in the use of advanced phishing kits in a large-scale campaign in June.

Vulnerability Spotlight: Vulnerabilities in Alyac antivirus program could stop virus scanning, cause code execution.

Update (Aug. 3, 2022): Talos disclosed two new vulnerabilities in the Alyac antivirus software and added their details to this post.

Cisco Talos recently discovered out-of-bounds read and buffer overflow vulnerabilities in ESTsecurity Corp.’s Alyac antivirus software that could cause a denial-of-service condition or arbitrary code execution. Alyac is an antivirus software developed for Microsoft Windows machines.

TALOS-2022-1452 (CVE-2022-21147) is a vulnerability that exists in a specific Alyac module that, eventually, leads to a crash of Alyac’s scanning process, which effectively neutralizes the antivirus scan.
