Sorry to hear you got compromised — that really stinks. Hope you didn't lose any sweet loot or anything. About Ishtar Commander: I've been using the app ever since the author released it and am part of the beta testing for the app. The author is very vocal on security has developed the app to be as safe and secure as Bungie has allowed the app to be. He actually wrote up a long post on security since he seems to get a lot of questions about it. http://unintuitive.com/blog/security-and-the-bungienet-destiny-api Also note that Bungie is very familiar with Ishtar Commander and the author, and if his app was doing anything shady or malicious Bungie would disable his API key in a hot minute!
