Malicious NuGet Packages Contain Delayed Logic Bombs

⚠️ Socket has identified nine malicious NuGet packages published in 2023–2024 by the account "shanhai666" that contain time‑delayed logic bombs intended to sabotage database operations and industrial control systems. The most dangerous, Sharp7Extend, bundles the legitimate Sharp7 PLC library and uses C# extension methods plus an encrypted configuration to trigger probabilistic process terminations (≈20%) and silent PLC write failures (≈80% after 30–90 minutes). Several SQL-related packages are set to activate on staged dates in August 2027 and November 2028, and the packages were collectively downloaded 9,488 times. All nine malicious packages have been removed from NuGet; attribution remains uncertain.
