  • Killed by Apple: Dark Sky isn't alone in Cupertino's Android app graveyard

    Unfortunately, Android users are no stranger to the effects of Apple’s spending spree. Over the years, Apple has bought some of the best and most beloved apps and left Android users twisting in the wind with no alternative other than to switch to an iPhone.

    And sadly, this won’t be the last time it happens. Apple has a history of buying and killing (or crippling) Android apps and services over the years with a smile, and with a ton of money, lots of clout, and a billion-plus customers, there isn’t much Google can do to stop it.

  • How to exploit parser differentials

    The move to microservices-based architecture creates more attack surface for nefarious actors, so when our security researchers discovered a file upload vulnerability within GitLab, we patched it right up in our GitLab 12.7.4 security release.
