Naturally, this makes security breaches of VPNs particularly frustrating and damaging. Recently, a breach of UFO VPN customers’ data was recently uncovered by the cybersecurity firm Comparitech. It’s made all the worse by the company’s claim that it is a “zero log” or “no-log” VPN service (via LifeHacker).

Who is affected by the breach
Users of both free and paid UFO VPN accounts were found in the breached database, which according to the company’s website could include approximately 20 million users. An article by Android Police identified several other VPN services that use a “common codebase and infrastructure” to UFO VPN and were guilty of similar leaks. These services include Fast VPN, Free VPN, Super VPN, Flash VPN, Secure VPN and Rabbit VPN. These services are smaller than UFO VPN, but have install totals of between ten thousand and one million each in the Play Store.
How did the breach happen
With roughly 1TB of user logs apparently exposed in the breach according to some reports, it would seem that UFO VPN’s definition of “zero” is wanting. The breach occurred due to a database of user logs and API access records that was left accessible “on the web without a password or any other authentication required to access it.” UFO VPN attributed the problem to “personnel changes caused by COVID-19” which lead to bugs that went uncovered, but regardless of the reasoning, the damage was done. The security researchers notified UFO VPN of the breach on July 1 and it took over two weeks for the company to shut down the database in question. Subsequently, it popped up a second time on July 20 with even more data including records up to July 19. The company has not yet responded to this second occurrence.
What data was exposed in the breach
Based on Comparitech’s review of the database the company believes that the user logs and API access records contained:
Account passwords in plain textVPN session secrets and tokensIP addresses of both user devices and the VPN servers they connected toConnection timestampsGeo-tagsDevice and OS characteristicsURLS that appear to be domains from which advertisements are injected into free users’ web browsers
What to do if your data was breached
The most critical threat is likely to be the exposed passwords. If you used UFO VPN or any of the other potentially impacted VPN services, and you reuse that password across any other services be certain to change it immediately. Your email address would likely also be exposed, the most likely threat there is simply phishing attacks which hopefully you are accustomed to avoiding anyway. The rest of the threats are based on decryption of your data to view your location and online activity while using the VPN service. Unfortunately, there is nothing really to be done about these issues as the data has already been exposed.
