Kaspersky has found what they deem as a jack of all trades malicious app they call Trojan.AndroidOS.Loapi. Like the Trojan AsiaHitGroup we discovered last month on Google Play, this malware can do all the things—it's a downloader, dropper, SMS Trojan, and can push ads all from the same malicious app. If left to its own devices, it could overheat the phone by taxing the processor, make the battery bulge, and essentially leave your Android for dead.
It seems creating Swiss army knife malware—lumping several uniquely malicious features into one catch-all malicious app—is becoming a trend. At least this time, the Loapi Trojan didn't make it onto Google Play.
Loapi capabilitiesdFor the purpose of hiding itself, Loapi poses (mostly) as a fake antivirus or, on the other end of the spectrum, adult content apps. It then asks for device administrator permissions to lock the screen of the mobile device, among other things. Furthermore, it takes the damage to another level by attempting to trick the user into thinking genuine anti-malware scanners are the real threat, and prompts to uninstall them if found. If that weren't enough, it comes with a host of other features, including:
- Cryptocurrency mining using the Monero platform
- Aggressively displaying advertisements
- Sending/deleting/replying to SMS messages for the main purpose of Command & Control (C&C) capabilities
- Web crawling to subscribe the victim to various pay-for services
- DDoS attacking capability via a barrage of HTTP requests from the victim's device
With everything going on in the background, Loapi puts an extreme load on the mobile device. This can lead to the Android literally blowing up from heat produced by the maxed-out processor and battery.To state the obvious: This Loapi Trojan is quite nasty.
