VERY IMPORTANT

New version of a cryptocurrency-mining RETADUP worm (detected by Trend Micro as WORM_RETADUP.G) through feedback from our managed detection and response-related monitoring. This new variant is coded in AutoHotKey, an open-source scripting language used in Windows for creating hotkeys (i.e., keyboard shortcuts, macros, software automation). AutoHotKey is relatively similar to the script automation utility AutoIt, from which RETADUP’s earlier variants were based on and used for both cybercrime and cyberespionage.
