Fiesta Toolkit Description

Type: Possibly Unwanted Program

The Fiesta Toolkit is a hacking tool that has been associated with a dramatic increase in spam email sent out in 2013. The Fiesta Toolkit has been used in a large number of attacks that culminated in billions of spam email messages, of which nearly two hundred million contained dangerous infected file attachments. Although PC security researchers reported that the number of spam email messages worldwide declined in 2012, spam email messages doubled in early 2013, associated with a strong increase in malware attacks involving the Fiesta Toolkit and other dangerous exploit packs. The vast majority of these attacks targeted computer systems in the United States, although many originated from former Soviet countries and the current Russian Federation.

Scams Involving Fiesta Toolkit Besides Email Spam

The Fiesta Toolkit has been associated with large scale spam email messages and with high profile DdoS attacks that targeted important banking institutions in order to steal money and financial information. Many computer users that have been affected by the Fiesta Toolkit will not realize that they have become victims of these attacks, realizing suddenly that their computer is sending out spam email and being used to distribute malware. The Fiesta Toolkit is essentially a collection of exploits that can be used to take advantage of vulnerabilities in a computer in order to install malware. Because of this, the Fiesta Toolkit can essentially be used to install any type of malware, ranging from banking Trojans and spyware, to all kinds of browser hijackers and adware.

How Fiesta Toolkit and Other Exploit Kits Work

Most exploit kits take advantage of various known vulnerabilities in software or in operating systems. These vulnerabilities can often be fixed by updating the software in question and applying the latest security patches. It is common for computer users to be redirected to an attack website containing the Fiesta Toolkit after visiting a compromised website that contains a malicious redirect script. A real time malware scanner can help prevent these kinds of redirects. Among the most common vulnerabilities exploited by the Fiesta Toolkit are vulnerabilities in the Java Runtime platform, Adobe Reader and Microsoft Office. To prevent these attacks, ESG security researchers advise disabling these kinds of programs when unused and always keeping all software on the infected computer fully up to date.
