Android users, beware! Your devices might be under attack. A recent report reveals a shocking number of malicious Android apps lurking on Google Play, with over 42 million unsuspecting users falling victim. But here's where it gets controversial: these apps were downloaded during a relatively short period, from June 2024 to May 2025.
Zscaler, a cloud security company, has uncovered a disturbing trend. In the past year, there has been a significant surge in malware targeting mobile devices, with a 67% growth rate. The primary culprits? Spyware and banking trojans, which are becoming increasingly prevalent.
The tactics of cybercriminals are evolving. They are moving away from traditional card fraud and embracing social engineering techniques like phishing, smishing, SIM-swapping, and payment scams to exploit mobile payments. This shift is attributed to the improved security measures, such as chip-and-PIN technology, and the widespread adoption of mobile payment systems.
But wait, there's more! The report highlights a concerning rise in banking malware, with a staggering 4.89 million transactions recorded in 2025. However, the growth rate has slowed compared to the previous year, indicating that this threat is not going away but evolving.
Zscaler's findings reveal a worrying increase in malicious apps on Google Play. This year, they discovered 239 harmful applications, up from 200 last year, with a collective download count of 42 million. And this is the part most people miss: these apps are becoming more sophisticated and harder to detect.
The Android ecosystem is also witnessing a rise in adware, now accounting for 69% of all detections, almost double the previous year's rate. The Joker info-stealer, once the top threat, has been dethroned, dropping to second place with a 23% share. Meanwhile, spyware has seen a massive 220% YoY increase, with SpyNote, SpyLoan, and BadBazaar families being the main culprits.
Geographically, India, the United States, and Canada bore the brunt of these attacks, receiving 55% of the total. But the most startling revelation is the massive spikes in attacks targeting Italy and Israel, with a staggering 800% to 4000% YoY increase.
Zscaler's report shines a light on three particularly harmful malware families. Anatsa, a banking trojan, has repeatedly infiltrated Google Play through seemingly harmless productivity apps, each time amassing hundreds of thousands of downloads. Its latest variant can compromise data from financial institutions, cryptocurrency platforms, and even new regions like Germany and South Korea.
Android Void (Vo1d) is another menace, infecting Android TV boxes, primarily in India and Brazil, running outdated Android Open Source Project versions. This backdoor malware has already compromised over 1.6 million devices.
Xnotice, a new Android RAT, targets job seekers in the oil and gas industry, especially in Iran and Arabic-speaking regions. It spreads through fake job application apps and exam registration tools, stealing banking credentials and sensitive information.
To protect yourself, Zscaler advises Android users to stay vigilant. Keep your device updated, trust only reputable publishers, be cautious with permissions, avoid unnecessary apps, and regularly scan for threats.
The report also sheds light on IoT device security. Routers remain the top target, with hackers exploiting vulnerabilities to add them to botnets or use them as malware delivery proxies. The U.S., Hong Kong, Germany, India, and China are emerging as hotspots for IoT attacks, indicating a broader geographic reach.
To combat these threats, organizations should adopt zero-trust technology for critical networks and strengthen IoT and cellular gateways with anomaly monitoring and firmware-level protections. Mobile defenses should include SIM-level traffic scrutiny, anti-phishing measures, and strict application control policies.
