Security readout for executives and security teams
PuTTY beta 0.67 for Windows could load malicious DLL files from the current working directory. If an attacker can place a fake DLL where a user launches PuTTY, code may run as that user. Sources do not show active exploitation or a confirmed fixed version. Exposure appears limited to systems running PuTTY beta 0.67, especially where users launch it from writable folders, downloads, shares, or unpacked archives. The source bundle does not identify broader affected versions. Treat as a targeted workstation hygiene issue, not an internet-wide emergency. Prioritize removal of the old beta build from managed endpoints and shared tool folders because compromise could execute code as the affected user. Mitigation focus: Identify and remove PuTTY beta 0.67 where present.; Check official PuTTY guidance for fixed or supported replacement versions.; Avoid launching PuTTY from downloads, shares, or other writable directories..
