Next week’s Monster Scale Summit will be scary good. Keynotes include @kelseyhightower.com, @martin.kleppmann.com, @chris.blue, @gwenshap.bsky.social, @rstephens.me & @adamhjk.me. Given the price of admission (zero) and travel time (also zero), there’s really no excuse to miss this!

The tablets feature
of ScyllaDB is very impressive. It simplifies maintenance and looks like a solid foundation for possible autoscaling www.scylladb.com/2024/12/03/e...
ScyllaDB 2024.2 Introduces New Efficiency & Elasticity via “Tablets” - ScyllaDB
Scaling operations with Tablets are up to 30X faster while reducing network costs by up to 50%

I'm watching some folks reverse engineer the xz backdoor, sharing some *preliminary* analysis with permission.

The hooked RSA_public_decrypt verifies a signature on the server's host key by a fixed Ed448 key, and then passes a payload to system().

It's RCE, not auth bypass, and gated/unreplayable.
This might be the best executed supply chain attack we've seen described in the open, and it's a nightmare scenario: malicious, competent, authorized upstream in a widely used library.

Looks like this got caught by chance. Wonder how long it would have taken otherwise.
Woah. Backdoor in liblzma targeting ssh servers.

www.openwall.com/lists/oss-se...

It has everything: malicious upstream, masterful obfuscation, detection due to performance degradation, inclusion in OpenSSH via distro patches for systemd support…

Now I’m curious what it does in RSA_public_decrypt
