Phishing
is no longer a worry solely in the domain of eBay, PayPal and major financial
banks. Thanks to a sophisticated attack dubbed rock phishing, the targets of
phishing attacks have widened and the attacks have become more pervasive,
longer lasting and harder to block.
Rock phishing
gained its funny name back in 2005 when security researchers first noticed the
phenomenon. They were seeing a large number of phishing sites crop up in a
pattern-like manner, where a single malicious domain could act as seed for many
unique phishing subdomains. One of the unifying factors of all these sites was
that at the time most had subdirectories containing the word ‘rock’ within
them.
As researchers
looked into the increasing number of these types of phishing sites two things
became evident. First, this massive volume
of sites was being generated by an automated kit. And second, the kit was the
handiwork of a shadowy group of criminals they dubbed the “Rock Phish Gang.”
According to a study conducted by researchers
from Cambridge University, more than 50 percent of more than 35,000 unique
phishing attacks between February and April 2007 were rock phish attacks
perpetrated by this gang.
But it isn’t just
the Rock Phish Gang getting in on the rock phish act any more.
“Now it is many
gangs and is basically a technique that is being duplicated across the Internet
by online thieves that would like to steal from anyone who is available to be
stolen form,” said Ihab Shraim, Chief Security Officer for MarkMonitor, an
enterprise brand protection company.
The gang’s method
has proliferated throughout the Internet—its brainchild worked so well that
other criminals were attracted to replicate the code or make their own kits.
“A lot of other phishing kits are starting to
just get referred to as rock phish, where it is almost synonymous with phishing
kits—sort of like Kleenex with tissue,” said David Cowings, senior manager of
operations for Symantec Security Response. “It started out with one individual
group (using them) but now it has turned into open source code which everyone
uses for their own means.”
Since its first
discovery, rock phishing’s productive sites no longer use the telltale “rock”
within their addresses—they became too easily detectable by security filters
set to look for the word. However, the moniker remains—even if it is sometimes
confusing since it refers to the gang that invented it, the method itself and
to the kits that perpetrate it.
Like traditional
phishing attacks, a rock phish attempt is geared toward gaining a vital piece
of information from the user to hijack an account or steal an identity. But
even though the name of the game is very similar, these attacks are very
different behind the curtains.
“This
is not your standard phish attack where you spoof the headers of the email and
you try to lure the user to click on a URL,” Shraim said. “It uses multiple
tactics: botnets, fast flux networks, proxies, traffic load balancers and
redirectors, as well as DNS record manipulation. The combination is used in one
attack. This is more sophisticated, more targeted and quite relentless
(compared to a standard phish).”
