A team managed to crack a 512-bit DKIM key for less than $8! They extracted the private key from a public RSA key, which allowed them to sign emails as if they were the original sender. Despite being deprecated since 2018, they found over 1,700 public DKIM keys shorter than 1,024 bits on the top 1M websites. Find out how they did this and learn why emails signed with this compromised key passed the DKIM verification checks of some major email providers.Projects
