You must be new here...

This sort of thing has been going on for months - years. Read the 
archives )-:

Right now, I have a telco in Romania deliberately trying to hack into 
several of my client sites - they must have bandwidth to spare, as even 
with firewalling, they're still going strong.

At least, I'm assuming it's a telco - it's definitely a telephone/ISPs 
company's computer that is the source and it doesn't look like a generic 
server/cloud type VPS thing either. It seems to be owned by "iLink 
Telecom" whoever they are - so I'm assuming this is a dodgy eastern 
European telco trying to steal free calls from the rest of the world.

The sad thing is that they're running the old, fucked-up version of 
sipvicious - the one that keeps on trying, even when it's firewalled out. 
It's been going on to several of my sites for over 3 days now - it peaked 
on one site at 1.5Mb/sec, but it's averaging 400-500Kbps to each site 
right now.

The site is which maps to terminators.micos.ro. Hm. just 
noticed this morning that there are at least 2 separate attacks to one 
particular host of mine. Ah well. All their succeeding in doing is wasting 
their own bandwidth. Hope they have to pay for it.
