DroidCleaner, an Android app that claims to free up smartphone memory but actually infects connected PCs, has been removed from Google Play but is still available from third-party app stores.
Kaspersky Lab claims that DroidCleaner demonstrates a new attack vector against PCs. While it has come across PC malware that infects connected smartphones, this is the first time it has found malware going from phone to PC.
When it discovered the malware, it was available from the official Google Play app store (Google has since removed it). It’s an app that promises to accelerate Android smartphones by freeing up memory – but it doesn’t. A very basic GUI display 'pretends' this is happening to deceive the user; but, in reality, it first downloads a trojan known to Kaspersky as Backdoor.MSIL.Ssucl.a, and then waits for the user to connect the device to a PC – “for example,” suggests Kaspersky, “to change the music files on the device.”
Successful transfer from the device to the PC is via autorun.inf. This is perhaps the least efficient part of the malware since the latest Windows operating systems have AutoRun disabled by default for external drives. However, Kaspersky suspects that there are enough older versions used by enough ‘unsophisticated’ users to make the malware worthwhile for the attacker. “It is those users who use outdated OS versions that are targeted by this attack vector,” says the company.
