Hack collective D33Ds Company has posted login details for more than 453,000 Yahoo accounts in plaintext. Hackers used a union-based SQL injection to penetrate a Yahoo subdomain. Yahoo Voice, also known as Associated Content, identified from the string “dbb1.ac.bf1.yahoo.com” The data is unconfirmed by Yahoo, though, so it may pay to change any Yahoo password you have in possession of. The hacker collective hopes the disclosure will be “a wake-up call, and not a threat””]
