Google Disrupts Massive Proxy Network Hijacking 9 Million Android Devices
SAN FRANCISCO, Calif. — Google announced on February 27 that it has dismantled what it believes to be the world’s largest residential proxy network, a sprawling operation that hijacked approximately 9 million Android smartphones, computers, and smart home devices worldwide. The network covertly routed internet traffic through unsuspecting users’ devices, enabling cybercriminals and other actors to mask their online activities behind millions of legitimate IP addresses.
According to Google’s Threat Intelligence Group, the proxy network was linked to a company called IPIDEA and operated through hidden software development kits (SDKs) embedded inside over 600 free Android apps. These apps, which ranged from utilities to VPN tools, appeared to function normally, leaving users unaware that their devices were being conscripted into the network. Once installed, the apps enrolled the devices into a residential proxy system that relayed internet traffic for third parties without user consent.
“Most people had no idea their devices were being used since the apps worked normally, and nothing looked broken,” a Google spokesperson said, highlighting the stealthy nature of the operation. The hijacked devices effectively became relay points for activities such as web scraping, automated login attempts, and other potentially illicit online actions. Because the traffic appeared to originate from residential IP addresses, it complicated efforts to trace and block malicious actors.
This disruption is a significant victory in the ongoing battle against cybercrime and unauthorized use of consumer technology. The Federal Bureau of Investigation’s Cyber Division has long warned about the rise of residential proxy abuse, which undermines internet security and privacy. By dismantling this network, Google has helped protect millions of users from unwittingly supporting criminal enterprises.
Experts note that residential proxies are particularly difficult to detect because they exploit legitimate devices and IP addresses, making malicious traffic blend seamlessly with normal internet usage. The Cybersecurity and Infrastructure Security Agency emphasizes the importance of vigilance when downloading free apps, recommending users only install software from trusted sources and regularly update their devices.
Google’s operation involved identifying the malicious SDKs and collaborating with app developers and platform providers to remove the compromised apps from the Google Play Store. The company also notified affected users and encouraged them to uninstall any suspicious applications to regain control of their devices.
“This takedown demonstrates the power of coordinated threat intelligence and proactive security measures,” said a representative from Google’s Threat Analysis Group. “We urge users to remain cautious and to monitor their devices for unusual behavior.”
As cybercriminals continue to innovate, the incident underscores the need for robust defenses and awareness. The Federal Trade Commission advises consumers to review app permissions carefully and to be skeptical of apps requesting excessive access.
With billions of connected devices worldwide, the risk of such proxy networks remains a pressing concern. Google’s disruption of this massive hijacking scheme marks a critical step in safeguarding the digital ecosystem and protecting users’ privacy and security.
