Cisco says 77 of its routers open to 'drive-by pharming'
The easiest solution: Change the default password
Computerworld - Cisco Systems Inc. is warning users that nearly 80 of its routers are vulnerable to a hack tactic that got play last week.
Dubbed "drive-by pharming" by Symantec Corp. and university researchers who first publicized the danger in a paper, the attack involves luring users to malicious sites where a device's default password is used to redirect them to bogus sites. Once they are at those sites, their identities could be stolen or malware could be force-fed to their computers.
In an advisory posted Thursday, Cisco listed 77 vulnerable routers in the lines sold to small offices, home offices, branch offices and telecommuters. The advisory recommended that users change the default username and password required to access the router's configuration settings, and disable the device's HTTP server feature.
The paper, co-written by a Symantec researcher and two other researchers from Indiana University (download PDF), urged a similar move by router owners.
The researchers also argued that router makers should stop using blank or easy-to-guess passwords, such as "admin," and switch to the device's serial number. "This value, which is unique to each individual router, would comprise a very secure and unpredictable password," the report stated.
