Navy and government administrators may have been able to breathe more easily with hacker menace the Deceptive Duo out of the way but, following an anonymous tip-off, it looks like others may have taken up the cause.

An email received by vnunet.com this morning told us to check out a Navy subdomain, tracker.hroc.navy.mil, which is apparently used to track CVs and job applications.

Sure enough, the site had been defaced this morning by a group calling itself 'Infidelz'.

According to the tip-off, confidential data was accessed and the hackers had published an edited document on the defaced page purporting to be from the human resources department of the Navy.

A message from the defacers read: "Files on this server were accessed containing names, social security numbers, addresses, telephone numbers and the confidential personal information of job applicants."

The site has since been taken down, but yesterday another Navy site, simamail.erl.mrms.navy.mil, was hit in a similar fashion by the same group.

Infidelz does not seem to have the same political motivations as the Deceptive Duo, which claimed to be exposing holes to help secure the US infrastructure.

Instead they appear to be OpenBSD evangelists hitting on high-profile and government Windows systems for the hell of it.

"The US Navy keeps exposing its weak security. Why they don't use OpenBSD, the free pro-active operating system, is beyond me," the hackers said.
