Russian hacking group uses Dropbox to store malware-stolen data

Sergiu Gatlan reports:

Russian-backed hacking group Turla has used a previously undocumented malware toolset to deploy backdoors and steal sensitive documents in targeted cyber-espionage campaigns directed at high-profile targets such as the Ministry of Foreign Affairs of European Union countries.

The previously unknown malware framework, named Crutch by its authors, was used in campaigns spanning from 2015 to at least early 2020.
