Security researchers say they have
uncovered previously unknown attacks on routers which direct traffic around the
Internet, allowing hackers to harvest vast amounts of data while going
undetected by existing cyber security defenses.
The attacks replace the operating
system used in network equipment from Cisco , the world's biggest maker of
routers, the computer forensic arm of U.S. security research firm FireEye,
Mandiant, said on Tuesday.
So far, Mandiant has found 14
instances of router implants in India, Mexico, Philippines and Ukraine, the
company said in a blog post.
Separately, Cisco confirmed that it
had alerted customers to these attacks on Cisco operating system software
platforms.
The company said that it had worked
with Mandiant to develop ways for customers detect the attack, which if found,
will require them to re-image the software used to control their routers.
"If you own (seize control of)
the router, you own the data of all the companies and government organizations
that sit behind that router," FireEye Chief Executive Dave DeWalt said of
his company's discovery.
Routers operate outside the
perimeter of firewalls, anti-virus and other security tools which organizations
around the world use to safeguard data traffic.
Effectively, the $80 billion which technology
market research firm IDC estimates is spent annually on cyber security
tools offer no protection against this form of attack, according to FireEye.
The malicious program has been
dubbed "SYNful", a reference to how the implanted software can jump
from router to router using their syndication functions.
Computer logs from infected routers
suggest the attacks have been taking place for at least a year, FireEye's
DeWalt said.
Cisco said SYNful did not take
advantage of any vulnerability in its own software. Instead it stole valid
network administration credentials from organizations targeted in the attacks
or by gaining physical access to their routers.
The affected routers have been used
to hit multiple industries and government agencies, DeWalt said.
The implanted software, which
duplicates normal router functions, could also potentially affect routers from
other makers, he said.
