Best Buy "Thank You, Your Anti-Virus Protection Plan has been renewed" email leads to malware

Payload and approach seem to be exactly the same as this one, with a Bredolab dropper. Again, it routes through yummyeyes.ru and you should look for the same log entries of .ru:8080 and /x.html to make sure you are clean.

In this case the intermediate step is a hacked site at peninsula.co.nz/x.html but it probably varies.

If you are not in the US, then blocking bestbuy.com at your mail perimeter will do no harm.

Wow, over a year later and it looks like they are still using this tactic. I received two of these emails within the last month.
