Gearbox Software has issued a notice that malicious users on Xbox Live are targeting Borderlands 2 players with an external application aimed to sabotage characters of legitimate players. Thankfully, it looks like the malicious activity is easy to avoid and, furthermore, a fix for the issue has already been submitted for certification to Xbox Live.
From Gearbox CM Chris Faylor:
Recently a few users have begun violating the Xbox Live Code of Conduct by using an external application to maliciously disrupt the experience and sabotage characters of legitimate Borderlands 2 players on Xbox 360. Fortunately it’s easy to avoid this scenario.
After extensive internal testing, an update to prevent this disruption has been submitted to Microsoft and will be released as soon as possible. Until then, concerned Xbox 360 players of Borderlands 2 should consider playing online with trusted individuals in non-public sessions. This does not affect players on PC or PlayStation 3.
We also advise that before ceasing play, users always select "Save and Quit" from within the pause menu while their character is alive. If after the death of their character players find themselves at the main menu of Borderlands 2 instead of respawning in-game, be sure to immediately select "Continue" to resume playing as that character.
We ask that players report any suspicious behavior in Borderlands 2 to [email protected] and provide as much details and documentation of their disrupted experience as possible to assist us in our investigation.
If you're playing Borderlands 2 on Xbox 360, be alert and follow these simple guidelines to avoid having some serious damage done to your saved character.
