More than 1.5 million Web pages have suffered a huge SQL -injection attack, dubbed as the Lizamoon attack.
The attack got its name after the first website to be infected by it.
Security company Websense, which has been tracking the attack, said that it first discovered the attack on 29 March when around 28,000 Web pages were infected by the attack.
The company said the attack is a kind of SQL injection attack, where cyber criminals inject malicious code into the database of PHP- and ASP-based websites.
The aim of the attack is to dupe users by frightening them. The infected Web pages display false virus warnings to users, tricking them to buy anti-virus software. But once the user downloads the software, the virus exposes their computers to hackers.
Websense has said that the attack had also infected some iTunes podcasts Web pages.
