yossarian (1.3.6.1.4.1.55738)

my colleagues Alexis and Brad at @trailofbits put together a great post on a basic security mistake that we keep making: attacker-controlled recursion. my favorite thing about these is that they're (1) trivial to find and (2) *way* more impactful than normal DoS spam.

the post contains some great examples of these, including real vulnerabilities in Protobuf and ElasticSearch:

they'll also be presenting their findings at @DistrictCon tomorrow!

Periodic reminder to the fedi EE / embedded systems community: I have a lot of lab capabilities and resources that the average hobbyist can't afford, and am willing to offer them up on reasonable terms (i.e. FREE in many cases) to help people out.

As a general rule if you're not making money on it (i.e. hobbyist/noncommercial/academic project) and it's not a major time commitment or consumable cost for me, all I ask is that you pay return shipping if you want the hardware sent back to you afterwards. For anything large or commercial in nature, I'm still potentially interested but we'd have to discuss compensation first.

Capabilities and equipment available:
* 3D planar EM simulation (Sonnet Pro)
* 5 3/4 digit multimeters (R&S HMC8012)
* Various oscilloscopes to 16 GHz BW (PicoScope 6424E, LeCroy WaveRunner 8404M-MS, LeCroy SDA 816Zi-A) plus power rail, current, and differential probes
* VNA measurements to 8.5 GHz (PicoVNA 106 / 108)
* BERT BER/eye pattern/bathtub curve measurements to 28 Gbps (MultiLane ML4039-BTP)
* Vector signal generation to 6 GHz (Siglent SSG5060X-V)
* Fine pitch soldering and PCB rework, BGA assembly, inner layer circuit edits, etc
* Low magnification stereo microscopy
* High magnification reflected light optical microscopy to ~300nm resolution, including large area automated step-and-repeat scanning and stitching of multi-gigapixel datasets
* Coming soon: Embedding and cross section polishing for failure analysis etc

Reminder for those using the iOS Patreon app to support their creators: Apple is now taking a 30% cut for new donations through the app, plus whatever Patreon takes. Consider alternate donation methods (including direct to the Patreon website rather than the Apple mobile app).

Iโ€™ve found, btw, that ko-fi has the best deal for creators - for a $72 annual fee, they do not take any cut of donations.

I hope you're all doing risk assessments and checking the exposure of your business/NGO/public institution to the US weaponizing its tech infrastructure (Google, Microsoft, Apple) and shutting down your operations if they disagree with your mission?
