Malware injection attack is spreading like wildfire these days, and countless websites have been affected. The attack is done via a compromised FTP, and many believe that the virus can actually “sniff out” FTP passwords and send it back to the hacker. The hacker then uses your FTP password to access your website and add malicious iframe coding to infect other visitors who browse your website.
