A former core infrastructure engineer at an industrial firm has been sentenced to prison for an insider cyber extortion plot. According to SecurityWeek, the engineer deleted administrator accounts and reset hundreds of passwords, locking out legitimate users and disrupting access to critical systems.

The engineer then demanded 20 bitcoin in exchange for sparing the company's servers. The scheme ultimately failed, and the engineer was convicted and sentenced to prison.

The case highlights the threat posed by trusted insiders with privileged access, who can cause significant damage before being caught. This account is based solely on the SecurityWeek report, and no other sources were available for comparison.
