Fake linkedin invitation emalis lead to malware attacks Cyberoam internet threat Report

November 2010 by Cyberoam

Cyberoam, a division of Elitecore Technologies and the innovator of identity-based Unified Threat Management (UTM) solutions, today announced the Q3, 2010 Internet threats trend report, prepared in collaboration with its partner, Commtouch. The report brought out several recent episodes of LinkedIn users being bombarded with fake invitations and reminders, leading to a variety of malware pages including PC infections by data theft Trojans.
The emails, which looked like official Linkedin messages, claimed that pending invitations awaited the recipient’s response thereby, prompting him or her to visit their supposedly Linkedin email inboxes. However, clicking the email links only led to a variety of malware and garden-variety pharmacy web pages.

Says Abhilash Sonwane, VP-Product Management, Cyberoam, “We are seeing an increasing trend where users of social networking sites are becoming victims of brutal malware attacks because of the huge popularity of these sites. If as an individual user, you come across several annoying LinkedIn invites in your Gmail inbox, simply report them as Spam, especially if you didn’t recognize the name of the person who’s inviting you. Some of these LinkedIn invites are being sent to organizations to skilfully collect personal information. Thus, organizations should encourage individuals to promptly delete such requests.”

This quarter also saw incidents where URLs of popular shopping sites were abused by Phishing scam operators without the site owner being aware of such abuse. In one such incident, a webpage exactly resembling Paypal.com used the URL of a shopping site, was set up to collect log-in information of the Paypal account holder. Another set of well-crafted emails mimicking Amazon.com order confirmations were detected, all of which led to short-lived malware websites.

In other stories, popular courier agencies DHL and FedEx featured in Top 25 sites that sent fake invoice emails with malware attachments. Spam levels averaged 88% of all email traffic throughout the quarter, peaking at almost 95% in mid-September. India, which had unceremoniously emerged as the number one zombie hotspot in the last quarter, again claimed the top zombie producer title with a marginal increase of 1%.
