Researchers at security company FireEye have revealed an advanced persistent threat targeting the U.S. defense and aerospace industries and likely originating in China. Named Beebus after an early sample, the campaign's attacks come in continuous waves over time against strategically chosen individuals. According to an unnamed inside source, the Beebus campaign began in early 2012 when FireEye noticed suspicious activity on the systems of some its defense and aerospace clients. Of 261 discovered attacks, 123 targeted unmanned aerial vehicle or systems vendors. The most recent exploit used a Deloitte industry analysis report sent in a weaponized email. Researchers believe that the campaign has so far touched 214 servers with 60 unique IP addresses.
