A new Russian-speaking group has targeted medical labs, banks, manufacturers and software developers in Russia. The group, dubbed OldGremlin, began operating with custom tools as early as March of this year. The attackers insert their hacking tools into networks via malware downloaded through spearphishing emails, then encrypt files and hold them ransom for about $50,000. The most recent successful attack identified by Group-IB, which has offices in Singapore and Moscow, was against a clinical diagnostics laboratory in August.”]
