More than 6.4 million LinkedIn passwords have been downloaded by a user on a Russian internet forum in an apparent hack. While some LinkedIn login details are encrypted, users have been advised to change their passwords on the popular networking site.
Apparently, the weaker passwords utilized by LinkedIn users — around 300,000 — have been cracked already. Other users may have contacted fellow hackers in an apparent bid to seek help in cracking the encryption. Some LinkedIn users are reporting strange link requests from unknown persons. Clicking on these link requests may expose users to virus risk. The Finnish security firm CERT-FI is warning that the hackers may have access to user email addresses also, though they appear encrypted and unreadable.
