Security readout for executives and security teams

This is an old ICQ for Windows issue where the client may not show a full long filename. A malicious executable could appear to the user as a safer file type, increasing the chance they open it. The sources do not provide a CVSS score, confirmed patch, or current exploitation evidence. Exposure is most likely limited to legacy systems still running Win32 ICQ 98a 1.30 or similar-era ICQ clients. Modern environments are unlikely to be affected unless old software remains installed or available on unmanaged endpoints. Treat this as a legacy software hygiene issue, not an emergency, unless ICQ 98a-era clients are still present. Priority should be inventory, removal, and controls preventing users from opening untrusted executables from obsolete messaging tools. Mitigation focus: Inventory endpoints for legacy ICQ clients and remove unsupported installations.; Do not rely on legacy client filename displays for trust decisions.; Block or restrict file transfers through obsolete messaging software..
