Manufacturer Rootkits, Dangerous Dongle, Physical Visualisation, and Cryptoed Comms

  1. Popular Chinese Android Smartphone Backdoored By ManufacturerCoolpad is the third largest smartphone builder in China, and ranks sixth worldwide with 3.7 percent global market share. It trails only Lenovo and Xiaomi in China and is the leader of China’s 4G market with 16 percent market share. Coolpad outsells Samsung and Apple in China, and has said it plans to expand globally with a goal of 60 million phones worldwide. For now, its high-end Halo Dazen phones are the only ones containing the backdoor, Palo Alto said. Backdoor enabled installation of other apps, dial numbers, send messages, and report back to the mothership. The manufacturer even ran the command-and-control nodes for the malware.
  2. USB Driveby — dongle that plugs into USB, and tries to root the box. Specifically, when you normally plug in a mouse or keyboard into a machine, no authorization is required to begin using them. The devices can simply begin typing and clicking. We exploit this fact by sending arbitrary keystrokes meant to launch specific applications (via Spotlight/Alfred/Quicksilver), permanently evade a local firewall (Little Snitch), install a reverse shell in crontab, and even modify DNS settings without any additional permissions.
  3. Physical Data Visualisationsa chronological list of physical visualizations and related artifacts. (via Flowing Data)
  4. Dissentan anonymous communication substrate intended primarily for applications built on a broadcast communication model: for example, bulletin boards, wikis, auctions, or voting. Users of an online group obtain cryptographic guarantees of sender and receiver anonymity, message integrity, disruption resistance, proportionality, and location hiding. And a pony.
