Technology blog TechCrunch Europe has fallen foul of the notorious ZeuS Trojan which was recently responsible for stealing £700,000 from UK banks.
Earlier today the site tweeted news of a malware warning about the site, which was later revealed to be a hard to detect ZeuS variant.
Code on eu.tech has been changed to redirect visitors to a malicious PDF file.
If the PDF is run, it will exploit a vulnerability and allow the Trojan to be downloaded.
TechCrunch is now believed to have cleaned up the site.
