Exclusive: Palo Alto chose not to tie China to hacking campaign for fear of retaliation from Beijing, sources say Palo Alto Networks opted not to tie China to a global cyberespionage campaign the firm exposed last week over concerns that the cybersecurity company or its clients could face retaliation from Beijing...

Scoop: A report published last week outlined what Palo Alto researchers believed was a China-linked hacking campaign.

But after an intervention from execs, the report's language was changed to refer more vaguely to "a state-aligned group that operates out of Asia."

#BREAKING #ESETresearch identified the wiper #DynoWiper used in an attempted disruptive cyberattack against the Polish energy sector on Dec 29, 2025. At this point, no successful disruption is known, but the malware’s design clearly indicates destructive intent. 1/5

Great work by Kim and ESET to get this story out there. The cyber threat has been off the front pages with everything else going on, but is still very real.
