- Cybercriminals who targeted Ukraine are actually Russian government hackers, researchers say
For years, Russian government hackers have used several made-up personas to hide their tracks and try to trick security researchers and government agencies into pointing the blame in the wrong direction.
They have pretended to be a lone Romanian hacktivist called Guccifer 2.0 when they hacked the Democratic National Committee; unleashed a destructive malware designed to look like run-of-the-mill ransomware; hid within the servers used by an Iranian hacking group; claimed to be an Islamist hacking group called Cyber Caliphate; hacked the 2018 Winter Olympics leaving breadcrumbs that pointed to North Korea and China; and slipped false evidence within documents released as a hack and leak operation supposedly carried out by an hacktivist group called Cyber Berkut.
Now, security researchers claim to have found a new Russian government false flag.
