My friends said I was crazy for taking extra math classes for fun ... they were right ... until now
I'm seriously debating going back to school for a math degree now

Made a small pdf, with one page repeated a ton of times to test resource exhaustion against pdf parsers. It's not fancy, but I couldn't find something that did it already, so I quickly made something that did. Any other cool PDF parser attacks? gist.github.com/coldwaterq/f…

Not sure if I'll use Mastadon any more than I've used twitter, but defcon.social/@coldwaterq
Ever wondered what kinds of #machinelearning files could contain pickles. Let me know what I missed so than anyone attempting to avoid getting exploited can, and anyone looking for exploit targets can as well. #cybersecurity #DataScience github.com/coldwaterq/pickle…
Some examples of search engine optimization are probably types of targeted evasion against recommender systems. “How can I get ranked as highly as possible in a broad range of categories?” in direct contradiction to the engine’s goals.

The Wayback Machine has been the only snapshot of many early infosec conferences, and the only way InfoconDB could catalog and document what happened at these cons. InfoconDB could not exist as it does without the Internet Archive and Wayback Machine.

One important note - functionality of the model is retained and gives outputs like normal.
So glad I had the opportunity to present at #DEFCON30!! If you want to inject a mythic c2 agent into a pickled #MachineLearning model (default for most python frameworks) you can find the code for the wrapper at github.com/MythicAgents/pick….

We have ~21 challenges donated by ~5 orgs that span all manner of ML attacks. Big shoutout to @GTKlondike @josephtlucas @JankhJankh @rharang @comathematician @ColdwaterQ @BenevOrang for their time and effort. Stay tuned for more details!
The AI Village is proud to announce our CTF for @defcon 30. Evade, poison, steal, and otherwise hack AI and ML systems. There'll be something for everybody, so check it out. Follow for more details.

I had a blast the one time I competed in @DefConScavHunt so +1 for this recommendation.

Which is why you could play @DefConScavHunt We make you go everywhere and interact with just about everyone!

If anyone wants to see me talk about embedding backdoors into existing pickled AI/ML models I'll be talking in Track 3 of Defcon at 1PM on Friday 8/12. If you want to watch it online, I'm guessing it may be broadcast at twitch.tv/defcon_dctv_three

Here is a small demo of my latest project, an ICMP backdoor listener that waits for a payload in the ethernet frame to then connect back with a reverse shell, both the implant and the code to generate the ping packet are in Go asciinema.org/a/SvNWp9d8a6U3…
