Participated at the workshop Vehicle Spy with Intrepid by the Automotive Security Research Group at Shackspace (Stuttgart) and really liked it (despite me looking asleep all the time due to critical caffeine levels).

TIL: Don’t attack the crypto. Attack the implementation.

Found it. I was looking for this SSD for months. Scavenged it back today 😀

840 EVO SSD from Samsung

Picked my KW902 apart today to see what’s inside. It features probably a SN65HVDA1050A CAN tranciever (ISO 11898-2 high speed up tp 1 Mbps) a BK3231S SoC for Bluetooth 3.0 and 4.0 programmable via JTAG/FLASH both controlled by a PIC18F25K80 (cheapest of the family, also up to 1Mbps bit rate, comforms to CAN 2.0B) programmable via ICSP.

KW902 ODB2 dongle on the inside

The pins for ICSP may be exposed on the cable for the LED and RST button but since I don’t have the equipment to read out the firmware I didn’t look too closely and called it a day – for now. This cheap IC costs ~2 EUR btw and is well documented.

tl,dr: `systemctl suspend`

Sometimes I let my pc play music at night. Spotify still didn’t manage to implement a sleep function (even gorram Audible has this – and chances are the app crashes way before anyway).

I usually use `shutdown -h 60` or similar. Suspend tho? That’s another story. Hint: “suspend” is a bash builtin and not what you’d expect 😉

Looks like this changed (again) from `pm-suspend` to… systemd:

> sleep 1h; systemctl suspend

No sudo. yw.
