Sanctions are hitting Russia hard. Cyber conflict continues at a low level, and the slow Russian invasion of Ukraine has moved into a more brutal, indiscriminate phase.
Russian cyberattacks against Ukraine were under preparation for some time before the invasion.
SecurityWeek has an update on ESET's research into Russian cyberattacks against Ukrainian targets. The company says it's detected a worm, HermeticWizard, that's spreading HermeticWiper, which, as its name suggests, is data-erasing malware. ESET has also found HermeticRansom in the wild, which adds a capability for extortion to the campaign. CrowdStrike has also detected the Go-based ransomware, which it's calling "Party Ticket," but which it confirms is the same malware as HermeticRansom. Kaspersky assesses the ransomware as misdirection for the wiper campaign, which would be consistent with Russian practice at the outset of the war against Ukraine.
There are reports of "local" Russian jamming of GPS in and around Ukraine, but so far, Breaking Defense reports, their effect seems relatively contained. US support operations in particular are said to be unaffected.
Ukraine and its sympathizers strike back against Russia in cyberspace.
Ukraine has shown some ability to attract hacktivists and volunteer hackers to its cause, the Wall Street Journal reports, and Vice describes some of their activities, many of which have taken the familiar form of vandalism, defacing websites and performing other mischief.
Of arguably more significance have been signs that Ukraine has been able to obtain, and publish, material from online Russian sources. Ukrainska Pravda reports that "The Centre for Defence Strategies has acquired the names of 120,000 Russian servicemen who are fighting in Ukraine." These have been posted online. That's unlikely to have any tactical effect, but it can't be good for either morale or for Russian confidence in the security of its networks. There are also reports that some FSB files have been taken.
