The Dawn of AWS Zombies

    πŸ“‚ Hacking,Internet     # ,     πŸ—¨ No Comments

One of the less enviable tasks in a techie's life is identifying bogus robot traffic on their networks.

The past week the security universe has been pounded by a whirlwind of bad press and bad actors.

It seems the banner scammers/hijackers have figured this out too. Recently I noticed suspicious Adwords bannersΒ originating from a site called adnxs.com.
