E-mail hosting company Servers Australia was the victim of a hack attack on Friday which spammed its customers with offensive e-mails by assuming the company's domain name.

A company source said the company is "almost 100% sure" the attack exploited a flaw in its Kayako security appliances which allowed the attacker to spam its users.

According to the source, the hacker blindly injected the HTML spam into the support system but was denied access to client information.

Servers Australia Manager Jared Hirst reassured the company's customers in an e-mail response, that their personal data was not compromised and warned against following the links provided in the e-mails.
