Many of the LinkedIn emails alerts instructing users on how to reset passwords accessed by hackers were dumped into spam boxes, according to email security vendor Cloudmark.
In a blog post on Tuesday. Andrew Conway, a Cloudmark researcher, said a substantial increase in spam reports last weekend were traced to LinkedIn password reset email alerts
In many cases, the emails that users' marked as spam were legitimate alerts from LinkedIn, Conway said.
"Over 4% of the people receiving this email thought it was spam and sent it straight to the bit bucket," Conway said. "If Linkedin sends out 6.5 million emails, then a quarter of a million people are congratulating themselves on avoiding spam -- and still have a compromised Linkedin password."
