Teenagers have recently gained attention for using Big Mama VPN to cheat in the virtual reality game Gorilla Tag. By side-loading the app onto Meta’s Oculus headsets, players exploit location delays to gain an unfair advantage. While this usage might seem relatively harmless, the real issue lies in how Big Mama’s residential proxy network operates. Researchers have linked the app to cybercrime forums where it is heavily promoted for use in activities such as distributed denial-of-service (DDoS) attacks, phishing campaigns, and botnets.
Cybersecurity firm Trend Micro discovered that Meta VR headsets are among the most popular devices using Big Mama VPN, alongside Samsung and Xiaomi devices.
They also identified a vulnerability in the VPN’s system, which could have allowed proxy users to access local networks. Big Mama reportedly addressed and fixed this flaw within a week of it being flagged. However, the larger problem persists: using Big Mama exposes users to significant privacy risks.
When users download the VPN, they implicitly consent to having their internet connection routed for other users. This is outlined in the app’s terms and conditions, but many users fail to fully understand the implications. Through its proxy marketplace, Big Mama sells access to tens of thousands of IP addresses worldwide, accepting payments exclusively in cryptocurrency.
Cybersecurity researchers at firms like Orange Cyberdefense and Kela have linked this marketplace to illicit activities, with over 1,000 posts about Big Mama appearing on cybercrime forums.
Big Mama’s ambiguous ownership further complicates matters. While the company is registered in Romania, it previously listed an address in Wyoming. Its representative, using the alias Alex A, claims the company does not advertise on forums and logs user activity to cooperate with law enforcement. Despite these assurances, the app has been repeatedly flagged for its potential role in cyberattacks, including an incident reported by Cisco Talos.
Free VPNs like Big Mama often come with hidden costs, sacrificing user privacy and security for financial viability. By selling access to residential proxies, Big Mama has opened doors for cybercriminals to exploit unsuspecting users’ internet connections. This serves as a cautionary tale about the dangers of free services in the digital age. Users are advised to exercise extreme caution when downloading apps, especially from unofficial sources, and to consider the potential trade-offs involved in using free VPN services.
