Kerberos has lost some of its bite, according to the US government, which on Wednesday warned of a critical flaw that could allow hackers to circumvent the secure networking system.

    Kerberos was invented by the Massachusetts Institute of Technology and is used by many large businesses as a way of keeping their networks secure. It uses strong encryption to verify the identity of any machine using a networked resource.

    On Wednesday, the Computer Incident Advisory Capability (CIAC) of the US government Department of Energy issued the warning, which originated at MIT. The flaw allows an attacker to gain unauthorized access to the key distribution center (KDC), which authenticates users, effectively compromising the security of the entire network.
