The Troj_STARTPA.AET Trojan is associated with a clever social engineering scam that involves convincing unsuspecting computer users to download fake updates for their Web browsers. Troj_STARTPA.AET is spread by malicious scripts that prompt computer users to download Web browser updates, typically through a pop-up advertisement. The Troj_STARTPA.AET scam mixes a social engineering scam with scareware tactics and, in some cases, even browser hijackers. Hundreds of computers around the world have been exposed to the Troj_STARTPA.AET scam. It is important to remember that all software updates should be downloaded directly from your software manufacturer's official website and never from third party sources such as pop-up messages or third party websites asking you to update your Web browser.

Troj_STARTPA.AET Attack Mixes Several Types of Known Online Scams

The main reason why the Troj_STARTPA.AET scam has caught the attention of ESG security researchers is because Troj_STARTPA.AET effectively mixes several kinds of scams in order to attack computer users with greater accuracy. In many cases, Troj_STARTPA.AET will use a browser hijacker to change the victim's homepage to a website claiming that the victim's browser needs to be updated. Phony, fake updates are also a typical part of many scareware scams which rely on convincing computer users to download fake, expensive updates for their rogue security software. It is also important to note that the Troj_STARTPA.AET infection would not be possible without its clever social engineering strategy which relies on tricking computer users into thinking that their Web browser is out of date.

The website where computer users are directed contains a script that determines the victim's Web browser. It then offers the victim an update for that Web browser. The page will typically be designed to use logos and messages identifying it as an affiliate of Mozilla Firefox or other popular Web browsers. Once installed, Troj_STARTPA.AET changes the victim's homepage to a similar website which allows criminals to install additional malware on the victim's computer. The main danger of the Troj_STARTPA.AET scam is the fact that these fraudulent websites are designed to look very convincing. In fact, they are so realistic that they can even trick more experienced computer users into thinking that they are dealing with an actual browser update website rather than with a known online scam. It is important to note that not even mobile browser users are safe from this scam, since these malicious websites can also cause fraudulent SMS charges.
