Phishers are increasingly using emails that appear to have been sent via social media networks. An analysis of the effectiveness of those phishing campaigns showed that the emails most likely to be clicked by employees were sent from LinkedIn.  Phishing emails asking users to ‘add me as a contact’, ‘reset password’, ‘new message,’ and invitations to ‘join network’ were effective 41% of the time.

Since many individuals use their work email addresses for their LinkedIn accounts, and also use of the same password for their work email account and their LinkedIn account, falling for such a scam could see their work email account compromised as well as their LinkedIn profile. With access to work email accounts, phishers can launch further scams and plunder the accounts for sensitive data.
