XZ backdoor: "It's RCE, not auth bypass, and gated/unreplayable."
Summary: Filippo Valsorda reports on a reverse-engineering effort of the xz backdoor. Preliminary analysis reveals that the hooked RSA_public_decrypt verifies a signature on the server's host key by a fixed Ed448 key, then passes a payload to system(). It's an RCE, not an auth bypass, and is gated/unreplayable.

Notes on El Salvador
Summary: In 1995, El Salvador had a record high intentional homicide rate of 139 per 100,000. However, in 2023, the rate dropped to 2.4 per 100,000, largely due to President Nayib Bukele's successful anti-crime crackdown. The country has been under quasi-martial law since 2022, with about 1.7% of the population in prison. This turnaround has made El Salvador safer than its neighbors, Guatemala and Honduras, whose rates remain 5-10 times higher.
