The Librarian Ghouls hacker group has compromised hundreds of Russian devices and used them to mine crypto in an apparent case of cryptojacking, cybersecurity firm Kaspersky says.
The hacker group, which is also known as Rare Werewolf, gains access to systems through malware-ridden phishing emails disguised as messages from legitimate organizations that appear to be official documents or payment orders, Kaspersky said in a report on Monday.
