Cisco has confirmed that a password protection system for entry to its customer portal has been compromised.
The networking vendor has reset passwords as a precautionary measure, and claimed that the incident is unlikely to be due to a weakness in Cisco products or technologies.
Early yesterday, registered users who tried to login were greeted with the statement: "Cisco has determined that Cisco.com password protection has been compromised."
The warning explained that all passwords had been reset as a precaution, and instructed users to email Cisco for their new password. Users were told to call technical support if they did not receive an answer within five minutes.
It is feared that thousands of Cisco customers' details could have been disclosed, and that outsiders may have accessed restricted information and tools.
Many customers have also reported problems in receiving new passwords to access the site.
