IMPORTANT SECURITY UPDATE: BISim Recommends Immediate Download of Latest Version of WIBU Systems CodeMeter

WIBU Systems recently notified Bohemia Interactive Simulations (BISim) of a potential security issue related to WIBU’s CodeMeter licensing system, which is used for BISim product licensing. According to WIBU’s security advisory, “In order to exploit the vulnerabilities, attackers must have access either to the system itself or to a system on the same network. Attackers must have already broken into or gained access to the network.

BISim recommends customers promptly download and install, for all computers which have BISim products deployed, the latest version of WIBU CodeMeter to address this issue.

WIBU CodeMeter: Customers can download the latest WIBU CodeMeter software (ca. 50 MB) directly from BISim, linked below.
