A researcher in Holland has found that his Xiaomi smartphone has a vulnerability allowing attackers to silently install any app they wish. He found an app named Analytics.apk routinely sends data about the phone back to the Xiaomi servers, and more importantly checks for an update every 24 hours. This means if someone acts as a man in the middle and renames any malicious app as Analytics.apk, it will be downloaded and installed automatically, without the user knowing.


Bruce Schneier wrote an interesting post about what looks to be a huge, and sustained operation to probe critical infrastructure on the internet. It seems like a nation state is testing capabilities and weak points, potentially to use in a cyber war scenario to take down the entire internet, using targetted DDoS attacks.

In other denial of service news, researchers from Ben-Gurion University have found that it would take only 6000 smartphones to take down a states emergency phone system, and around 200,000 for the entire system across the US. They theorized that malware infected phones could launch a distributed attack, overwhelming the system, and bringing it to its knees.

To finish, we have a great article by Robert Epstein, about how Silicon Valley tricked us into giving up our freedom, privacy, data, and behavioral patterns, in return for “free” stuff. Definitely check this one out if you're into these sort of ideas.
