SUMMARY:Sounds Legit: Why you shouldn't trust that speaker
DESCRIPTION:BadUSB devices are popular worldwide\, and almost no one ignore
 s their nature: an object with a USB connection (usually a pendrive) conne
 cts to a computer and tells it "I am a keyboard"\, proceeding to send ("ty
 pe") arbitrary commands\, usually malicious. In this talk we have decided 
 to go beyond the classic concept of a malicious pendrive. We use a set of 
 classic USB speakers from a well-known brand available worldwide\, which w
 e disassemble to add our own hardware modification. This modification\, wh
 ich consists of cheap parts that can be acquired worldwide\, makes this se
 t of speakers an unprecedented local and remote attack vector: a device th
 at looks and functions as a speaker\, but is capable of acting as a keyboa
 rd\, exfiltrate information\, and use a SIM card to receive remote command
 s by telephone to leak information. When connected\, the speaker passively
  waits for a phone call to its internal SIM from a specific number. Upon r
 eceiving it\, launches a payload against the computer to which it was conn
 ected\, allowing the attacker to obtain a shell. Now then\, what would hap
 pen if someone left this speaker in its original box in a corner of an off
 ice? What would happen if someone connected this innocent device to their 
 work terminal? Well\, it is a speaker after all. And it definitely sounds 
 legit...\n\nSpeaker(s): Luis Ángel Ramírez Mendoza (@larm182luis)\, Maur
