Clickjacking Attacks In-The-Wild

Via Windows Secrets Newsletter (Issue 172)

In last week's Top Story, Windows Secrets associate editor Stuart Johnston described a technique being used by bad guys to infect your PCs and steal your personal information. Now we hear from a reader named Graham, who has first-hand experience that clickjacking attacks are real and likely to become more common.

"Yep, clickjacking is in the wild. I build, fix, and de-badware computers for family, friends, and businesses. I had a friend complain that his eBay page kept popping up with auctions when he hadn't accessed eBay. So, dutifully, I went to see what was going on and found that he had been trawling through some [game] crack sites.

"When he clicked some links, he would also pop his eBay page up (he had his eBay cookie set). Bingo! The crack-page vendors had scored his login details. I quickly apprised him of the risks of visiting said pages and, of course, quickly reset his eBay password and scanned, cleaned, and disinfected his computer.

"Hopefully, I have left him a much wiser if not a safer surfer. So the hack is out there and, I am sure, soon to spread to more legitimate sites as hackers break into badly protected Web pages. And I am sure more nastiness will soon present itself rather than this more benign attack (and I am not lessening the seriousness of this type of attack, just that this was easily fixed)."

To repeat the precautions that Stuart outlined in his article: (1) use the Firefox browser with Giorgio Maone's NoScript script-blocking add-on installed (donation requested) and allow only trusted sites to run scripts, (2) update to the latest version of Adobe's Flash Player, and (3) stay away from questionable sites.

I'm not 100% sure this was clickjacking...but we will go with it until proven otherwise.
