    New research has heightened an already urgent call to abandon SHA-1, a cryptographic algorithm still used in many popular online services. A new, powerful GPG collision attack on the system which could enable attackers to fake digital certificates has been discovered.

    In a paper called SHA-1 is a Shambles, researchers Gaëtan Leurent and Thomas Peyrin have demonstrated a new, powerful attack on the system that could enable attackers to fake digital certificates for as little as $45,000.

    Leurent, from INRIA in France, and Peyrin, from the Nanyan Technological University in Singapore, demonstrated their attack by creating a fake digital certificate using the GNU Privacy Guard (GPG or GnuPG) system.
