Package managers have an integrity problem
Trail of Bits tested 25 package managers against compromised mirrors and found many lack basic cryptographic integrity checks — a systemic supply-chain blind spot CRA auditors will probe.
Summary written by editorial AI · Source link below
I tested 25 of the most popular package managers to check whether they detect a compromised package repository injecting malicious code into legitimate packages. This code integrity problem could be solved using cryptographic hashes or signatures, but many package managers are still vulnerable to this threat. Of the 25 package managers reviewed 1 , fewer than half used lockfiles that checked for tampering by default, and only two verified the integrity of every package they downloaded. Supply-ch
Editorial Analysis
If your build pipeline trusts package managers that do not verify download integrity, a compromised mirror can silently inject malicious code into production software.
Inventory all package managers in use, confirm cryptographic verification is active, and proxy downloads through a repository manager with mandatory integrity checks.
Many widely used package managers cannot detect tampered downloads — a supply-chain risk that EU regulation will increasingly scrutinise.
