Hackers attack Cisco flaw
Hackers made some attempts Friday to bring down network routing gear by exploiting a flaw in Cisco Systems Inc. equipment that carries the bulk of the world's Internet traffic.
There were no immediate reports of outages or slowdowns, suggesting that network administrators heeded Cisco's warnings about the flaw and implemented workarounds or installed the free patch.
"Cisco is aware that there have been isolated incidences of attempts to exploit the vulnerability," company spokesman Jim Brady said Friday. "We have no confirmation of any networks being impacted. There are no reports of any successful attacks."
Security researchers, however, warned that the exploit - a snippet of software code that takes advantage of the flaw - has been available for a short time and hackers may just be trying it out before attempting major attacks. Cisco first publicly warned of the flaw in its Internetwork Operating System software on Thursday.
