Quarterly figures

According to Kaspersky Security Network, in Q3 2022:

• A total of 5,623,670 mobile malware, adware, and riskware attacks were blocked.
• Droppers (Trojan-Dropper), accounting for 26.28% of detections, were the most common threat to mobile devices.

  • 35,060 packages were related to mobile banking Trojans,
  • 2,310 packages were mobile ransomware Trojans.

Quarterly highlights

Judging by the number of attacks on mobile devices, cybercriminal activity stabilized in Q3 2022 after a gradual drop in the previous quarters. Over the three months, Kaspersky products prevented a total of 5.6 million mobile malware, adware, and riskware attacks.

The new Triada Trojan, discovered inside a modified WhatsApp build, was an interesting find. It was notable for spreading via ads inside the popular Snaptube app and through the Vidmate internal store. Once on a device, the Trojan decrypts and runs a payload, which downloads and runs further malicious modules. The modules can display ads, subscribe the user to paid services, or download and run other malicious modules. Besides that, the Trojan steals various keys from the legitimate WhatsApp, potentially hijacking the account.

The Harly Trojan subscribers were another malware family spread via legitimate channels. These are published in Google Play under the guise of authentic apps, subscribing the unknowing user to paid services once installed. We have discovered 200 malicious applications of this type starting in 2020, and a total count of installations at the time of writing this report had exceeded 5 million.

One of the most recently detected Harly-type apps in Google Play, with more than 50,000 installations.

Google Play keeps getting new banking Trojans, such as new versions of the Trojan dropper that downloads and runs Sharkbot.

Despite a general decline in the number of mobile attacks, we can see that cybercriminals are using increasingly smarter tricks to deliver malware to user devices.

* Unique users attacked by this malware as a percentage of all attacked users of Kaspersky mobile solutions.

First and second places went to DangerousObject.Multi.Generic (22.58%) and Trojan.AndroidOS.Generic (14.59%), respectively, which are verdicts we use for malware detected with cloud technology. Cloud technologies are used when the antivirus databases lack data for detecting a piece of malware, but the company’s cloud already contains information about the object. This is essentially how the latest malware types are detected.

Trojan-Spy.AndroidOS.Agent.aas (8.51%), an evil twin of WhatsApp with a spy module built in, rose to third position. Trojan-SMS.AndroidOS.Fakeapp.d slid from second to fourth place with 6.95%. This malware is capable of sending text messages and calling predefined numbers, displaying ads and hiding its icon. Members of the Trojan.AndroidOS.GriftHorse family, which subscribe the user to premium SMS services, took fifth and sixteenth places.

Malware from the Trojan-Dropper.AndroidOS.Hqwar family, used for unpacking and running various banking Trojans, occupied sixth, fourteenth, and eighteenth places. These attacked a combined 6% of all users who encountered malware.

The verdict of DangerousObject.AndroidOS.GenericML came seventh with 2.90%. This verdict is assigned to files recognized as malicious by our machine-learning systems. Eighth place was occupied by Trojan-Dropper.AndroidOS.Agent.sl (2.46%), a dropper that unpacks and runs the banking Trojan from the Roaming Mantis campaign. Roaming Mantis mainly attacks users in Japan and France. Another banking Trojan dropper, Trojan-Dropper.AndroidOS.Agent.sl, sunk to ninth place with 2.21%.

Trojan-Downloader.AndroidOS.Necro.d, used for downloading and running other forms of malware on infected devices, jumped from sixteenth to tenth place with 1.93%. Trojan-Dropper.AndroidOS.Agent.rv, a dropper that unpacks and runs various types of malware, took eleventh place with 1.84%.

Twelfth place saw the arrival of the banking Trojan, Trojan-Banker.AndroidOS.Bian.h, with 1.71%. Trojan-Downloader.AndroidOS.Agent.kx, an adware dropper, accounted for 1.69%, climbed from twentieth to thirteenth place. Trojan.AndroidOS.Hiddad.hh, an adware Trojan that mostly attacks users in Russia, Kazakhstan, and Ukraine, was fifteenth with 1.52%.

Trojan-SMS.AndroidOS.Agent.ado, known for sending text messages to premium-rate shortcodes, remained seventeenth with 1.41%. Nineteenth place, with 1.35%, was occupied by Trojan-Dropper.AndroidOS.Triada.az, a type of malware that decrypts and runs a payload capable of displaying ads on the lock screen, opening new browser tabs, gathering device information, and dropping other malicious code.

The last in the rankings (previously thirteenth) is Trojan.AndroidOS.Soceng.f with 1,33%. It sends text messages to the user’s contacts, deletes files on the memory card, and overlays the interfaces of popular apps with its own window.
