Bit9 provides software and network security services to the U.S. government and at least 30 Fortune 100 firms. Hackers stole digital code signing certificates from Bit9’s network and used it to sign malware. The attackers then sent signed malware to at least three customers, Bit9 isn’t saying which customers were affected. The company said it has resolved the issue and is working with its customers to ensure they are no longer vulnerable to malware associated with the affected certificate. EMC Corp’s RSA Security division disclosed that it was breached in 2011.
