### Summary gitsign may select the wrong Rekor entry to use during online verification when multiple entries are returned by the log. ### Details gitsign uses Rekor's search API to fetch entries that apply to a signature being verified. The parameters used for the search are the public key and the payload. The search API returns entries that match _either_ condition rather than _both_. When gitsign's credential cache is used, there can be multiple entries that use the same ephemeral keypair / signing certificate. As gitsign assumes both conditions are matched by Rekor, there is no additional validation that the entry's hash matches the payload being verified, meaning that the wrong entry can be used to successfully pass verification. ### PoC Enable the credential cache and create commit signatures using the cached signing certificate. `gitsign verify` or `git log --show-signature` will demonstrate the use of the wrong entry index for the corresponding commit. Note that this depend...

Government and industry want to jump-start the conversation around "human-centric cybersecurity" to boost the usability and effectiveness of security products and services.

Episode #4: NIST's new post-quantum cryptography standards are here, so what comes next? This episode of Dark Reading Confidential digs into the world of quantum computing from a cybersecurity practitioner's point of view — with guests Matthew McFadden, vice president, Cyber, General Dynamics Information Technology (GDIT) and Thomas Scanlon, professor, Heinz College, Carnegie Mellon University.

CRON#TRAP is a new phishing attack using emulated Linux environments to bypass security and establish persistent backdoors. Leveraging…

Zero Trust security changes how organizations handle security by doing away with implicit trust while continuously analyzing and validating access requests. Contrary to perimeter-based security, users within an environment are not automatically trusted upon gaining access. Zero Trust security encourages continuous monitoring of every device and user, which ensures sustained protection after

The Iran-linked group Emennet Pasargad aims to undermine public confidence in Israeli and Western nations by using hack-and-leak campaigns and disrupting government services, including elections.

An ongoing campaign is targeting npm developers with hundreds of typosquat versions of their legitimate counterparts in an attempt to trick them into running cross-platform malware. The attack is notable for utilizing Ethereum smart contracts for command-and-control (C2) server address distribution, according to independent findings from Checkmarx, Phylum, and Socket published over the past few
