Cyber criminals began a campaign Monday that targeted LinkedIn users in a concerted spam attack, Cisco senior security researcher Henry Stern told ZDNet UK yesterday.
What was different from this specific campaign from previous one is the scale of the attack and the fact it targeted business users, he said.
“The combination of extremely high volume and the focus on business users suggests the attackers are interested in employees with access to online bank accounts,” Stern said. “We’ve provided LinkedIn with the information they need to take action against the spammers.”
During Monday, more than a quarter of the spam hitting Cisco nodes was due to this particular attack, Stern said, with billions of emails being sent. The emails were not targeted, but were designed for LinkedIn users to self-select, he added.
