Breaches and leaks

  • Comcast Xfinity: a flaw was found where one could extract the home address of customers, because of a weird login system that partially shows home addresses based on which IP you had, which could be spoofed.

  • GoDaddy: information on 31.000 GoDaddy servers was exposed in an unsecured s3 bucket, including juicy stuff like configuration details and price negotiations between them and AWS.

After being inspired by all the package manager problems we've seen recently, this researcher wanted to see if he could get access to Homebrew. He quickly found a Jenkins instance where a git token was visible, that gave him read-write access to Homebrew and all packages within. Nice cautionary tale for us all. Homebrew responded quickly and correctly.

Windows 10 Enterprise getting sandboxed execution feature
