A highly sophisticated, unpatched zero-day exploit is actively targeting users of Adobe Reader. Detected by the EXPMON threat-hunting system, this malicious PDF file is designed to
steal sensitive local data and perform advanced system fingerprinting.
The malware successfully
bypassed traditional antivirus tools, scoring a low initial detection rate on public scanning engines.
However, it triggered EXPMON’s advanced
behavioral analytics by exhibiting highly suspicious activities within the Acrobat JavaScript engine.
Once de-obfuscated and opened, the exploit abuses an unpatched vulnerability to execute privileged programming commands.
No official patch from Adobe is available to prevent the initial data theft.
