Topher Kessler over on sister site ZDNet notes that a Windows malware worm has been found embedded in an application being distributed in Apple’s App Store for iOS. The malware can be found in the free Instaquotes Quotes Cards for Instagram app, so you may want to avoid that app until a clean version is made available.
The malware in question is an old worm identified as Worm.VB-900. The fortunate thing is that the worm is old enough to be recognized as malware by just about any up-to-date anti-virus program you can think of, so the risk is minimal. In fact, it won’t effect iOS or OS X at all, but only users who manage their iOS Apps using iTunes and a Windows PC.
The curious thing for me is to wonder how such an old, low-threat worm ended up in an iOS App in the first place. It is difficult to imagine someone put it there deliberately. I mean, to what end? What would this malware accomplish?
But, if it was not put there deliberately, how did it get there? Anyone care to speculate?
