Multiple interpretation error in Trend Micro (1) PC-Cillin 2005 12.0.1244 with the 7.510.1002 engine and (2) OfficeScan 7.0 with the 7.510.1002 engine allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Security readout for executives and security teams

This is a legacy Trend Micro antivirus scanning bypass. Certain files could be mislabeled as safe because they start with bytes normally associated with Windows executables, while still being handled dangerously by end-user applications. Business risk mainly exists where the listed 2005-era Trend Micro products or engine remain in use. Exposure is most likely in legacy environments still running the named Trend Micro PC-Cillin or OfficeScan versions with engine 7.510.1002, or where old archived systems process historical email or web attachments. Treat this as a legacy risk review, not an emergency, unless affected Trend Micro products are still deployed. Priority should be removing obsolete antivirus dependencies and confirming modern mail and endpoint controls cover file-type confusion. Mitigation focus: Inventory Trend Micro PC-Cillin and OfficeScan versions and engine levels.; Retire or upgrade any affected legacy Trend Micro deployments.; Check Trend Micro guidance for fixed engines or supported migration paths..
