Joe Tidy "made his excuses and left [the chat room]"

So good to see the return of that traditional journalistic trope, so sadly missing since Digger Murdoch shuttered the News of the Screws (sorry, the News of the World).

Ukraine’s HUR cyber unit claims it crippled Russia’s fast payment system (SBP) with a DDoS attack — disrupting transactions nationwide and causing $30M in damages.
⚡ Cyber warfare now directly targets financial infrastructure.
💬 Do you think this sets a precedent for future state-backed cyber ops?

New Zealand sanctions Russia’s Unit 29155 (GRU hackers) over cyberattacks on Ukraine.

This group, also known as Cadet Blizzard / Ember Bear, was tied to WhisperGate & espionage across Europe. Sanctions: travel bans, asset freezes, and restrictions on funding.

💬 Are sanctions an effective tool in deterring state cyber units — or mainly diplomatic gestures? Share your take + follow @technadu for updates.

"Toward a Multi-Echelon Cyber Warfare Theory: A Meta-Game-Theoretic Paradigm for Defense and Dominance"

This is very interesting paper on cyber warfare from game theoretic viewpoint,
illustrating many points that might seem counterintuitive at first glance.

Screenshot showing AI assistant "asxiv" program explaining the formula that I 
highlighted in the PDF form of the paper.  Asxiv was discussed in https://news.ycombinator.com/item?id=45212535 and in one of my recent Mastodon posts.  The AI explanation of the formula was "The formula (\text{E}_{policy}(\theta) = (w*(\theta), B*(\theta))) means that the equilibrium at the policy level is determined by a tuple ((w*, B*)). (w*) represents the weights assigned to different strategic objectives, and (B*) represents the total resource budget allocated for cyber defense. Both of these are dependent on the technological state (\theta). This policy-level equilibrium sets the overall objectives and resource constraints for the strategic level" with some suggested followup questions shown below.Table 1 showing the correspondence between cyber warfare elements and various elements in game theory.

The latest edition of Underreported China by Sarah Cook is well worth a read. It covers the Chinese party-state's use of generative AI in disinformation campaigns, malware targeting Tibetans-in-exile and a report on prison conditions in Hong Kong
