Spoofed LinkedIn emails serving client-side exploits

Cybercriminals are currently brand-jacking LinkedIn in an attempt to trick end users into clicking on client-side exploits serving links found in the spoofed emails.

According to security researchers from GFI Labs, the spamvertised campaign is redirecting users to the Black Hole web malware exploitation kit, that is ultimately dropping a Cridex malware variant on the infected PCs.

Spamvertised subjects

• LinkedIn Invitation from your colleague
• LinkedIn Invitation from your co-worker
• LinkedIn Reminder from your colleague
• LinkedIn Notification
• LinkedIn private message

Spamvertised message:

• There are a total of 1 messages awaiting your response. Visit your InBox now.

End and corporate users are advised to avoid interacting with the emails, and to ensure that they are running the latest versions of their third-party software and browser plugins.
