writes "The Russian Business Network (RBN), a notorious hacker and malware hosting organization that operates out of St. Petersburg, Russia, has gone off the air, security researchers said.
According to a pair of Trend Micro researchers, RBN went dark around 10 p.m. EST Tuesday. "The routing information for their IP addresses has been withdrawn," said Paul Ferguson, a network architect at Trend Micro. "That's significant because while RBN has had connectivity issues in the past, then the routing [to its IP addresses] was still being advertised. This time, they've been voluntarily withdrawn.
He speculated that RBN is simply shifting to new digs, diversifying its considerable back-end infrastructure, trying to lay low or all of the above. "No one knows why they've done this, but I think they're down, not out," he said.
Jamz Yaneza, a Trend Micro research project manager, agreed. "We're seeing signs of RBN-like activity elsewhere, in Turkey, Taiwan and China. RBN may be moving to places even more inaccessible to the law [than Russia]. Everyone knows they were in St. Petersburg, but now they're changing houses, changing addresses.""Link to Original Source
