The Mandrake Android spy ware marketing campaign, which was first found in 2020, has seemingly made an unwelcome return. In a weblog put up this week, Kaspersky researchers reported that they discovered a suspicious pattern within the Google Play retailer this April that seemed to be a brand new model of the malware. After extra digging, they unearthed 5 Android apps containing the Mandrake malware that had been accessible on the shop for 2 years.
The researchers say that the brand new Mandrake has been upgraded with layers of obfuscation that enable it to bypass Google Play checks. Because of this, risk actors had been in a position to sneak a minimum of 5 apps onto Google Play containing the malware in 2022.
Most of those contaminated apps had been put in fewer than 1,000 instances, however the pretend file sharing app AirFS was put in over 30,000 instances. Much more troublesome, it was accessible on Google Play till March 2024, at which level it was lastly eliminated. Right here’s the complete checklist of Mandrake apps that the researchers say had been on Google Play for a minimum of a yr:
- AirFS – File sharing through Wi-Fi by it9042 (30,305 downloads)
- Astro Explorer by shevabad (718 downloads)
- Amber by kodaslda (19 downloads)
- CryptoPulsing by shevabad (790 downloads)

After the functions of the primary marketing campaign stayed undetected for 4 years, the present marketing campaign lurked within the shadows for 2 years, whereas nonetheless accessible for obtain on Google Play. This highlights the risk actors’ formidable abilities, and likewise that stricter controls for functions earlier than being revealed within the markets solely translate into extra subtle, harder-to-detect threats sneaking into official app marketplaces.”
