In Operation Endgame, a major operation this week disrupted a key infection chain used by cyber criminals. Within an international cooperation, 14.971 websites infected with SocGholish malware were remediated. This malware is used by a criminal group that plays a pivotal role in international cybercrime, namely: Evil Corp.

Shadow AI agents are rapidly spreading across enterprise platforms, often without IT or security visibility. Nudge Security explains how organizations can discover, assess, and govern AI agents before unmanaged permissions and autonomous actions create security risks.

The Raspberry Pi Pico is an excellent embedded platform, noted for its excellent documentation (and also the RP2040 microcontroller, one of the few that is currently not made from unobtainium). But one of the great features of this board is how it gets more and more support over time. And that’s why we used it as the basis for the CANPico.

DRAMATIS PERSONAE:

CryptoCAN is an encryption scheme for CAN messaging developed by Canis Labs. It’s designed to fit the publish/subscribe method of communication that CAN was designed for, and has a simple job: take a plaintext CAN frame, convert it into two ciphertext frames for broadcast on CAN, and at receivers, push these frames through a decoder to get back to the plaintext frame.

CAN bus wiring has a big effect on how fast data can go on CAN. CAN bits are normally 2000ns (2 microseconds, or 500kbit/sec) or longer for slower buses (a J1939 CAN bus runs at 250kbit/sec and can be up to 40m long). But CAN FD has the promise of much faster speeds on conventional CAN bus wiring, up to 8Mbit/sec (i.e. 125ns bit times). Yet most of the automotive industry is using CAN FD at just 2Mbit/sec or even slower. Why is this?

At first glance, an innocent little project for the Festive Season - Cheerlights on a Pico. Big Deal?!

This is the second CAN Quiz Question on the CAN protocol. This one is quite hard and not only tests knowledge of the dark corners of the CAN protocol, it also highlights a couple of important system design issues.

The question: There is a CAN node that’s acting very strangely on a 500kbit/sec CAN bus. What is happening?

This is a detective story about how a car was stolen - and how it uncovered an epidemic of high-tech car theft. It begins with a tweet. In April 2022, my friend Ian Tabor tweeted that vandals had been at his car, pulling apart the headlight and unplugging the cables.

This is a blog post about firmware updates, and I was inspired to write it by the news that NASA’s Curiosity rover on Mars has got an OTA update. The firmware image was about 21MB and took 11 days to send it over-the-air (or in this case, over-the-vacuum: Mars is currently 242 million kilometres from Earth).

The latest update of the open source can2 protocol decoder is able to automatically infer the sender of a CAN frame. It uses the method of deterministic distortion of CAN signals that result in frames from a given node on the bus having consistently shortened or lengthened recessive pulses. The differences can be quite small - just 10 or 15 nanoseconds - but they can be picked up by a suitably accurate logic analyzer.
