Analysis Summary

Indian threat actor Patchwork has been active since December 2015 and frequently uses spear phishing to strike Pakistan. PatchWork, (also known as Mahabusa, White Elephant, hangOver, VICEROY TIGER, The Dropping Elephant) is an APT that mainly conducts cyber-espionage activities against its targets. The group aims to steal sensitive information. In early July 2020, the Microstep Intelligence Bureau monitored a targeted attack with the help of the “New Coronary Pneumonia” hot event. 
In its most recent campaign, which ran from late November to early December 2021, Patchwork dropped a variation of the BADNEWS (Ragnatela) Remote Administration Trojan using malicious RTF files (RAT).

Patchwork is less advanced than its Russian and North Korean rivals, along with certain other East Asian APTs. This APT has targeted the Government of Pakistan, and the Ministry of defense in its most recent phishing campaign with a maldoc named “AML-CFT.doc” with Drops and side-loading file McVsoCfg.dll
