Your dependency scanner is a pattern matcher, not a security tool. A scanner that flags a known malicious script is a useful utility. It is not a defense.  The RUSTSEC-2026-0264 advisory regarding the proc-macro-en crate demonstrates this distinction. The crate, which had a single version published on 2026-08-20, was removed from crates.io after it was identified as containing a build script identical to the one found in the proc-macro1 supply chain attack. The associated user account was locked.  A careless reader looks at this and concludes that the ecosystem is being successfully defended by automated vigilance. They see a rapid removal and a locked account and assume the perimeter is holding.  This is the wrong conclusion.  The mechanism here is not a failure of detection, but a demonstration of recycling. The attacker did not invent a new way to compromise a build. They simply took a known malicious build script and applied it to a new name. The vulnerability is not in the code itself, but in the assumption that once a pattern is identified, the threat is neutralized.  If your security posture relies on the speed at which a database updates its list of known bad actors, you are not managing risk. You are merely participating in a race against a script that can be renamed in milliseconds.  The RUSTSEC-2026-0264 advisory shows that the attack vector is a commodity. The script is the same. The goal is the same. The only variable is the crate name.  True security in a supply chain does not come from better pattern matching of known malicious scripts. It comes from understanding the intent of the build process itself. If a crate does not need to execute arbitrary code during its build phase, it should not be allowed to.  Until then, your scanners will continue to report on the same recycled attacks, providing a false sense of progress while the underlying mechanism remains wide open. ## Sources - RUSTSEC-2026-0264 proc-macro-en attack: https://rustsec.org/advisories/RUSTSEC-2026-0264.html",
