Ethical hacking site Metasploit was itself hacked on Monday.
Metasploit is a site which provides information for those engaged in penetration testing and exploit research.
But it fell foul to hackers using the name "Evil Octal Security Team,"which replaced legitimate pages with Asian characters and the Englishmessage: "Hacked by Sunwear! Just for fun."
The hack was reported on the blog of security company Sunbelt Software.Comments on the blog made by "HD" -- thought to be Metasploit creator HD Moore -- said that Metasploit had fallen foul of ARP poisoning.
"Another customer on the same ISP was compromised and used to ARPpoison all servers in that subnet," wrote HD. "Metasploit.com
serverswere not compromised, nor have been to this date. It [the ARPpoisoning] was just used to 'deface' metasploit.com for glory."
HD said he rectified the problem by setting a static ARP entry and notifying the ISP. The site now appears to be back to normal.
