Today on my blog a spam comment appeared. I noticed a Youtube link being in the spam comment, which I found to be rather odd as no other link was distributed. I opened the link in a sandbox environment and it turned out to download a flash file of some sort, which seemed rather strange to me considering the url is a legit Youtube link as far as I can see:
The following link should be considered unsafe until otherwise proven!
m <DOT> youtube <DOT> com/e/7wQ-hZEVLeY
I tested the file using virustotal.com but not even a single anti-virus program flagged the file as being malicious.
I have a hard time believing that a spam comment was made containing only a single link, which downloads a flash file is not malicious so I am seeking assistence here to what the file actually is, if it should be considered malware and how it is possible to use Youtube to distribute this file. I am especially interested in that last question.
