I’ve been following offensive AI developments with great interest over the last year. I don’t think defenders yet appreciate how rigorously capable Agentic AI will test their attack surface. New blog with Morgan Adamski and David Ames on the topic. www.pwc.com/us/en/servic...

I testified to Congress that I believe the PRC operations prepositioning for disruptive effects in the US make it a bad idea to use TP-Link routers in millions of American homes. New reporting- the government appears to have reached the same conclusion! www.washingtonpost.com/technology/2...

U.S. agencies back banning popular home WiFi device, citing national security risk
The Commerce Department has proposed barring sales of TP-Link products, citing a national security risk from its China ties, people familiar with the matter said.

Predatory Sparrow strikes again. This time they drained funds from an Iran-based crypto exchange. Beyond theft, they targeted trust, undermining a key tool Iran uses to evade sanctions. Nobody with options will keep crypto assets there now. www.jpost.com/middle-east/...

This is a big deal. Predatory Sparrow’s past cyber attacks on Iranian steel plants and gas stations have demonstrated tangible effects in Iran. Disrupting the availability of this bank’s funds, or triggering a broader collapse of trust in Iranian banks, could have major impacts there.

I got to testify to the House Select Committee on the Chinese Communist Party last week. One focus area was the threat from TP-Link routers. Having 60% of the US consumer Wi-Fi market flooded with devices that get automatic software updates from the PRC is a risk we can't accept.

Ghidra 11.3 is OUT! 
PyGhidra is the new feature to be excited about.

It’s a Python library providing direct access to the Ghidra API. 

 I expect this to massively increase Reverse Engineering tool development, as it significantly reduces the barrier to entry for Ghidra interaction.
