research!rsc: The xz attack shell script
Andres Freund published the existence of the xz attack on 2024-03-29 to the public oss-security@openwall mailing list. The day before, he alerted Debian security and the (private) distros@openwall list. In his mail, he says that he dug into this after “observing a few odd symptoms around liblzma (part of the xz package) on Debian sid installations over the last weeks (logins with ssh taking a lot of CPU, valgrind errors).” At a high level, the attack is split in two pieces: a shell script and an object file. There is an injection of shell code during configure, which injects the shell code into make. The shell code during make adds the object file to the build. This post examines the shell script. (See also my timeline post.)

This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack surface, considering today’s AMD market share of around 36%… Read

The Curious Case of Predatory Sparrow
Reconstructing the Attack from a 4th party collector’s point of view Hamid Kashfi 18th December, Predator Sparrows launched a second attack against the fuel distribution system in Iran, similar to their previous operation in 2021. Since 2021, Iranian officials or third-party security vendors have not published any analysis or technical details about the original attack, which is not unusual. Their screenshots from the latest attacks provide some clues that only confirm our previous work, indicating connections to the “Yaas Arghavani” company, a VSAT and POS service provider for the fuel distribution system. The following is an old draft from December 2021, which I wrote for peer eyes rather than public view. The original draft focused on the first attack against the fuel distribution system. Still, some remarks remain valid and relevant to the recent attack on 18 Dec 2023, as little has changed regarding how the system works. The same infrastructure, same suppliers, and same 3rd party vendors, so we are likely just talking about a different attack vector and entry point from the previous case. I will probably draft a new note about the recent attack from scratch soon and when more details are gathered rather than updating the old speculative work.
