Update: Jagex has issued an announcement saying that no credit card or banking information was lost as a consequence of the breach. "Further to yesterday's announcement, we can affirm that none of RS Gold our players' card or bank details were compromised," it said. "We work with an industry-respected, entirely compliant third party payment processor, to intentionally avoid staff using gamers' full bank or card details. This also applies when players decide to save their information at payment period for any future purchases. Jagex undergoes routine, third-party testing to make sure we maintain the highest security standards"
His claims had been dismissed by a number of different gamers, several of whom suggested that it had been his own fault for not getting the account correctly secured, or that he may be lying around it entirely. However, it came to light today he wasn't lying, and that he was right regarding the data breach, which was actually an inside job at Jagex. "We affirm that a Member of The Old School Team was dismissed from employment at Jagex subsequent gross misuse of moderator privileges," Jagex stated in a statement posted today. "Throughout our rigorous routine system checks, irregular action was identified on small number of accounts, for example, movement of wealth and items back into the live match "
"Following our evaluation, we were able to solve the issue prior to any substantial impact was made into the broader game, or economy. We have also taken steps to return items and GP to any affected accounts. Whilst we generally do not return items or gold, we believe that given this unusual situationwe wanted to guarantee no players lost out into the rogue actions of a member of team "
Jagex added that it's"working with the authorities" regarding the incident--45 billion coins has significant real-world worth --but said it could not offer further details. He's also reportedly involved with the Reign of Buy OSRS Gold Terror clan, which was accused of using DDoS attacks to slow competitions in championships, including a $20,000 championship that occurred in September of this past year. Jagex said at the time that its investigation had found no evidence of wrongdoing by Sanderson, but in the wake of all this I anticipate it will be taking another look.
