The Russian hacking group Turla released an Android app that seems to aid Ukrainian hackers in their attacks against Russian networks.

Interesting paper by Lennart Maschmeyer: “The Subversive Trilemma: Why Cyber Operations Fall Short of Expectations“: Abstract: Although cyber conflict has existed for thirty years, the strategic utility of cyber operations remains unclear.

cyberwar, russia, Security technology, ukraine, Uncategorized

It has been interesting to notice how unimportant and ineffective cyber operations have been in the Russia-Ukraine war. Russia launched a wiper against Ukraine at the beginning, but it was found and neutered. Near as I can tell, the only thing that worked was the disabling of regional KA-SAT SATCOM terminals. It’s probably too early … Read More “Where’s the Russia-Ukraine Cyberwar?” »
