Cybercriminals continued to use legitimate channels to spread malware.

Similarly to 2021, we found a modified WhatsApp build with malicious code inside in 2022. It was notable for spreading via ads inside the popular Snaptube app and through the Vidmate in-app store.

The spread of malware through Google Play continued as well. In particular, we found several mobile Trojan subscribers on Google’s official Android app marketplace in 2022. These secretly signed users up for paid services. In addition to the previously known Jocker and MobOk families, we discovered a new family, named Harly and active since 2020. Harley malware programs were downloaded a total of 2.6 million times from Google Play in 2022. Also last year, fraudsters abused the marketplace to spread various scam apps, which promised welfare payments or lucrative energy investments.

Mobile banking Trojans were not far behind. Despite Europol having shut down the servers of FluBot (also known as Polph or Cabassous, the largest mobile botnet in recent years), users had to stay on guard, as Google Play still contained downloaders for other banking Trojan families, such as Sharkbot, Anatsa/Teaban, Octo/Coper, and Xenomorph, all masquerading as utilities. For instance, the Sharkbot downloader in the screenshot below imitates a file manager. It is capable of requesting permission to install further packages the Trojan needs to function on the unsuspecting user’s device.

Exploitation of popular game titles, where malware and unwanted software mimicked a pirated version of a game or game cheats, remained a popular mobile spread vector in 2022. The most frequently imitated titles included Minecraft, Roblox, Grand Theft Auto, PUBG, and FIFA. The malware spread primarily through questionable web sites, social media groups, and other unofficial channels.

First and third places went to DangerousObject.Multi.Generic (18.97%) and Trojan.AndroidOS.Generic (6.70%), respectively, which are verdicts we use for malware detected with cloud technology. Cloud technology is triggered whenever the antivirus databases lack data for detecting a piece of malware, but the antivirus company’s cloud already contains information about the object. This is essentially how the latest malware types are detected.

The Trojans in second and ninth places (8.65% and 2.37%) belonged to the Trojan-SMS.AndroidOS.Fakeapp family. This type of malware is capable of sending text messages and calling preset numbers, displaying ads, and hiding its icon on the device.

WhatsApp modifications equipped with a spy module, detected as Trojan-Spy.AndroidOS.Agent.aas (6.01%) and Trojan-Spy.AndroidOS.Agent.acq (1.34%) were in fourth and twentieth positions, respectively.

Scam apps detected as Trojan.AndroidOS.Fakemoney.d (4.65%) were the fifth-largest category. These try to trick users into believing that they are filling out an application for a welfare payout.

Members of the Trojan.AndroidOS.GriftHorse family, which subscribe the user to premium SMS services, took both sixth and eleventh places (4.32% and 2%, respectively).

The banking Trojan dropper Trojan-Dropper.AndroidOS.Agent.sl (3.22%) was seventh.

The verdict of DangerousObject.AndroidOS.GenericML (2.96%) sank to eighth place. The verdict is assigned to files recognized as malicious by our machine-learning systems.

Tenth place was taken by Trojan.AndroidOS.Fakeapp.ed (2.19%). This verdict refers to a category of fraudulent apps which target users in Russia by posing as a stock-trading platform for investing in gas.

Trojan-Downloader.AndroidOS.Agent.kx (1.72%) rose to twelfth position. This type of malware is distributed as part of legitimate software, downloading advertising modules.

Trojan.AndroidOS.Soceng.f (1.67%), in thirteenth place, sends text messages to people on your contact list, deletes files on the SD card, and overlays the interfaces of popular apps with its own window.

Malware from the Trojan-Dropper.AndroidOS.Hqwar family, which unpacks and runs various banking Trojans, occupied fourteenth and nineteenth places (1.49 and 1.35%).

Trojan.AndroidOS.Fakeapp.dw was fifteenth (1.43%). The verdict applies to a variety of scam apps, such as those supposedly offering the user to earn some extra cash.

Trojan-Ransom.AndroidOS.Pigetrl.a (1.43%) took sixteenth place. Unlike classic Trojan-Ransom malware, which typically demands a ransom, it simply locks the screen and asks to enter a code. The application offers no instructions on obtaining the code, which is embedded in the program itself.

Trojan-Downloader.AndroidOS.Necro.d sank to seventeenth position (1.4%). This malware is capable of downloading, installing, and running other applications when commanded by its operators.

Trojan-SMS.AndroidOS.Agent.ado, which sends text messages to shortcodes, was eighteenth (1.36%).

Mobile banking Trojans

We detected 196,476 mobile banking Trojan installers in 2022, a year-on-year increase of 100% and the highest figure in the past six years.

The Trojan-Banker.AndroidOS.Bray family accounted for two-thirds (66.40%) of all detected banking Trojans. This family attacked mostly users in Japan. It was followed by the Trojan-Banker.AndroidOS.Fakecalls family (8.27%) and Trojan-Banker.AndroidOS.Bian (3.25%).

Conclusion

The cybercriminal activity leveled off in 2022, with attack numbers remaining steady after a decrease in 2021. That said, cybercriminals are still working on improving both malware functionality and spread vectors. Malware is increasingly spreading through legitimate channels, such as official marketplaces and ads in popular apps. This is true for both scam apps and dangerous mobile banking malware.

Potentially unwanted applications (RiskWare) accounted for a majority of newly detected threats in 2022, replacing the previous leader, adware. Most mobile cyberattacks used malware as before.
