A large Spam campaign determined on Twitter during the last couple of years directed users to malicious websites that exploited vulnerabilities in web browser plug-ins to infect their computers with rascal antivirus programs, according to security researchers from antivirus firm Kaspersky Lab.

While monitoring the spam campaign for several hours, Kaspersky's researchers counted 4,148 tweets containing malicious links existence sent from 540 compromised Chirrup accounts.

"Our analytic thinking is just a snapshot at a given clock time, and is lower than reality," said Kaspersky Lab senior malware investigator Nicolas Brulez in a blog post on Wednesday.

The rogue tweets controlled messages such as "online virus check," "proven anti-virus," "excellent anti-virus," besides as links to websites with .TK and .TW1.SU orbit name calling.

The high variation of links, messages and hijacked accounts used in this spam political campaign could explain wherefore Twitter's automated spam filters weren't undefeated at blocking it.

In addition to traditional rogue scareware pages that use counterfeit antivirus alerts to trick users into downloading the vixenish programs, this campaign also used the BlackHole effort toolkit to infect computers without user interaction.

Even though scareware is not as prevalent these days as IT was a couple of years ago, worldly attack campaigns like this one, which need portentous resources to perpetrate off, suggest that so much applications still play an prodigious role in the cybercriminal ecosystem. Scareware has always been a best way of funding strange malicious operations that are not As productive.

As always, users should hold back all software installed on their computers, especially the browsers plug-ins, upfield-to-date, systematic to reduce their chances of existence affected by drive-by download attacks.
