Last week I think I may have had an intrusion attempt, or targeted malware attack through Pidgin Messenger. It may have just been some conflict, as they were in the process of trying to set up their Pidgin and maybe changing random settings while we were connected that did something weird. But I don't know them well either, and what I do know, they're kinda a jerk. So I don't trust them. And I've never seen Pidgin do anything like this before. If so, it was the first time in like 7 years I've had something like this happen. Fortunately I was running Pidgin in a restricted sandbox, and well hardened via outbound FW rules & D+ too. All that happened is my box froze for a few seconds. Then DEP kicked in and terminated Pidgin. Then I got my CCleaner prompt to delete the sandbox, and did so. And that was that. And if so, great timing too. I just updated the "Off-the-record messaging" plugin to version 18.104.22.168 And noticed it was hardened by adding DEP & ASLR to it. And it said in the notes for it something like: "We hope that no such vulnerability exists, but if so now it would just terminate the program instead of your entire system", or something. LOL... perhaps this person found such a vulnerability indeed? And adding DEP & ASLR to that plugin was a most welcome measure? Heck, maybe my name even got picked out of a hat for them to test it out on? But I was wondering, my situation aside... is it normal for DEP & SBIE to interact in this fashion to ward off attempted attacks? It seems logical that it would be. As DEP is designed to just crash/terminate a program when it becomes unresponsive instead of your entire system. And sandboxie will keep the attack isolated inside that app, which could cause it to become unresponsive. So I would think the two would work together like this quite often. But I don't have any test machine that I play around with stuff on, so I wouldn't know. This was my 1'st/only honest to goodness attempt against me since I've been on XP... "if" it indeed was one at all. And it happened to unfold that way. But logic leads me to believe this tandem kicking into action could be quite common.
