Former Apple Macintosh evangelist Guy Kawasaki posts Twitter messages about a lot of different thing, but the message he put up Tuesday was really out of character: “Leighton Meester sex tape video free download!”
His message included a link that, after some further clicking, landed Kawasaki’s followers on a fake porn site where online criminals try to install a nasty Trojan horse program on victim’s computers. And in an interesting twist, the program attacks both Mac and Windows users.  Read the full story [computerworld.com]

Criminals often register their own domain name to perform phishing attacks. Unlike the other common phishing site scenarios (including hacked servers, open redirects, and abuse of free webhosting), phishing sites that have their own domain name can be harder to remove, because the website owner and domain owner is the fraudster. Only the hosting and DNS providers and the domain registrar are able to take the site down and also likely to cooperate. Read the full story [netcraft.com]

A wave of fake Twitter email invitations sent in hopes of luring people to unzip a file to find out who invited them has been hitting unsuspecting victims. The message carries a mass-mailing worm. It looks around on infected computers and sends emails to addresses it finds.
The message appears as if it came from a Twitter account, but unlike a legitimate Twitter message, there is no invitation URL in the body of the email. Instead, the user sees an attachment that appears as a .zip file containing an invitation card. When the zip file is opened, the virus spreads. Read the full story [mediapost.com]

It doesn’t take much to get started in Internet crime these days. Find the right site, hand over $50, and you can start wreaking havoc with 1,000 already-infected PCs.
Finjan, a San Jose, CA security company, looked into the “Golden Cash” site, used by black hats to buy and sell the use of hijacked computers. The crooks behind the site infect PCs (or pay others to do so) with the Golden Cash remote-control malware, and then sell access to those PCs. And that access doesn’t cost much.  Read the full story [pcworld.com]
