  • The first hack was on January 17th during which an unidentified individual hacked the game admin’s Steam account, which the hacker used to log into the game and alter the multiplayer server settings. The hacker used the admin account to create World War II airplanes and tanks inside the server, killing players and damaging ships.
  • On January 20th, multiple players discovered and used a technical exploit in the ATLAS game to flood the servers with whales and dragons, placing them in water, on land and in the air. Both incidents led to the game makers having to roll back the servers on both occasions to undo all the spam.

  • A design flaw exists in the file transfer interaction between a client host and a MySQL server that allows an attacker running a MySQL server to access any data the connected client has read access to.
  • The issue concerns the LOAD DATA statement used with the LOCAL modifier. File-transfer requests are received by clients based on the information they provided in the LOAD DATA statement. A malicious server could reply with a LOAD DATA LOCAL statement and demand any file for which the client has read permissions.
  • The flaw could ultimately allow an attacker to retrieve information such as SSH keys or access details for cryptocurrency wallets.
