We have been reverse engineering the XZ Utils backdoor and are sharing some initial findings: we've identified multiple hooking options to adapt to different environments, and a hardcoded fake public key that can appear in verbose SSH logs depending on attacker-controlled flags. pic.twitter.com/P48blup7cN

Our research shows that this fake public key generates the following RSA-CERT hash which can appear in verbose SSH logs under the right conditions, and therefore might be useful for detection:

This evening we spent over 2 hours with @lauriewired on a livestream. Our goal was to follow suspicious URLs from Twitter (or online) to get malware.

Every single time we got surveys for free McDonalds.

2 hours. 0 malware.

Here is what we did find:

- Robux scam (not malware) on Harvard and Stanford (???)
- Robux scam spam on people's obituaries (we left a nice comment)
- Tons upon tons of fake porn sites which did nothing but try to take your credit card
- Fake Roblox Android apps that show ads

Today a couple of media outlets picked up on a patent filed by Roku in 2022.

In a brief summary: a patent which allows Roku to slipstream advertisements via the HDMI cable. It would allow content to be paused so advertisements can be displayed.

Austria is about to ban spying. Because of woke.

"The nation has the most permissive spying laws in Europe when it comes to hosting foreign agents on its soil, with current rules allowing intelligence operatives to ply their trade as long as they don’t spy directly on Austria".https://t.co/h2qWZOIggq

Google Books is full of AI-generated garbage. This is bad for a variety of reasons. One of them is that Google Books ultimately feeds into NGram Viewer, which is a tool academics use to do research on human culture and language https://t.co/9nckGnuXPI pic.twitter.com/Fi9oZT2Omd

3 standout snippets from this @guardian scoop on Indian assassinations

1. Directly learning from Mossad, Russia,& especially Saudi Arabia (inc desire to send message)

2. Pakistan colluded in fiction of secrecy b/c many targets are known terrorists

3…https://t.co/klUBiGbd6P

3. Sense of lots of states, including western states, engaging in extrajudicial killings overseas and so some in Delhi believe “India reserves the right to do the same”

1+2+3=more visible but unacknowledged operations to disrupt enemy and send message (& further erosion of norm)
