We had to block all of South America for a few days ... we had some open holes apparently.
The hacker was demanding we give him free servers (he was emailing us), or he'd continue his malicious activities ... we eventually blocked him entirely...but he was very persistent.
My cisco guy actually traced down his home IP, and got him kicked off his local ISP in brazil, I was fucking surprised that they did that for us. :thumbsup:
tidbits from it :
- He was using @london.com - informed me he took over their mail server and was using it for his maliciousness
- He was also using MIT, Yale, Harvard, high end school servers for his maliciousness (ip sources he was coming from trailed through all of these school servers...all *nix servers)...also had some local brazil government servers.
- He was using our cisco switches to get in, and actually got in through our VPN router at one point
I could go into a lot more detail, but that's the run down.
