Turla Crutch attacks Ministry of Foreign Affairs in an EU country, misuses Dropbox in cyber-espionage

ESET researchers discovered a previously undocumented backdoor and document stealer used for cyber-espionage. ESET has been able to attribute the program, dubbed Crutch by its developers, to the infamous Turla APT group. It was in use from 2015 until at least early 2020. ESET has seen Crutch on the network of a Ministry of Foreign Affairs in a country of the European Union, suggesting that this malware family is only used against very specific targets. These tools were designed to exfiltrate sensitive documents and other files to Dropbox accounts controlled by Turla operators.
