Last week, we touched on the growing threat of business email scams, a browser hijacker called Browsefox (a.k.a. Sambreel and Yontoo), a fake “rewards” page, a peculiar spam about “girls list”, and a quite scammy Instagram follower booster that actually leads to a browser extension PUP.

For our bi-monthly PUP Friday post, we featured an unwanted program claiming to alert users of possible zombie invasions.

We also saw a then-active malvertising campaign on MSN.com that was carried on by the same threat actors behind that operation against Yahoo! visitors we had also written about earlier this month. Users who visited MSN.com may find themselves affected by the Angler exploit kit in the process.
