      Tavis Ormandy Retweeted Avast

      Wow - Avast decided to disable their JavaScript interpreter globally! The vulnerability report they mention wasn't just me, it was a Project Zero collaboration with @natashenka 🔥🔥🔥 I think this is the right decision, it was a *lot* of attack surface.https://twitter.com/avast_antivirus/status/1237685343580753925 …

      1/2-Last week, 3/4 @taviso reported a vulnerability to us in one of our emulators, which in theory could have been abused for RCE. On 3/9 he released a tool to simplify vuln. analysis in the emulator. Today, to protect our hundreds of millions of users, we disabled the emulator.

      So how can they just disable this feature and not have their protection affected? Legacy code, maybe?

      I hear from informal chats there is brutal competition to win industry detection metrics, because customers will just pick the winner. Adding crazy features to score a single point wouldn't be questioned, as nobody picks the product with the smallest attack surface. 🤷🏻‍♂️

          ESET historically marketed based on having a small binary and lower overheads, still do for their business product. They did also produce an internet security product with lots of features ( read attack surface) so perhaps that was a reaction to that pressure

          Interesting point. I think that many people think that security is an afterthought only for IoT but this is seen over and over again across ALL industries. Make the shiniest object so people will buy it, or else!
