Security researchers say that they have found evidence that for the first time Russia-backed hackers are now using a more sophisticated type of malware to target government entities.

ESET presented its case Thursday that the hacker group, known as Fancy Bear (or APT28), is using rootkit malware to target its victims. That marks an escalation in tactics, which the researchers say the group’s hacking capabilities “may be even more dangerous than previously thought.”
