Symantec Identifies Android Trojans That Mutate With Every Download 97
angry tapir writes "Symantec researchers have identified a new premium-rate SMS Android Trojan that modifies its code every time it gets downloaded in order to bypass antivirus detection. This technique is known as server-side polymorphism and has already existed in the world of desktop malware for many years, but mobile malware creators have only now begun to adopt it."

it's not as elegant as polymorphic on it's own virus. it's server side generated, the server adds some randomization to the code changes classnames, adds'/removes unneeded code and then builds a new package. meaning the signature changes. Now, it's perfectly possible to build a binary and a new package _on_ device too, it just doesn't seem that any malware does it, polymorphic on device _and_ spread through bluetooth would be newsworthy I'd think(it needs the victim to press yes about 3 times and to open the file though - and the user to keep bt on too.. as it happens, you can't on android keep just the handsfree parts of bluetooth on, if you got bt on then obex is on, but you'll still need to accept the incoming files as said).

This is my only complaint about T-Mobile's customer service. The only way to block this is to pay $5/month and then micromanage your lines. -sigh-
I had this problem with my father's line. He somehow got signed up for all kinds of garbage, and we didn't figure it out until later. (Really gotta watch that bill better.) They reversed a few months' charges, but they're only willing to go back so far. (I don't blame them, there.)
But I did expect them to help me prevent the charges in the future, without me paying for the service.
