ActMobile data breach

Breach date: 2021-10-08. Added to this index: 2021-11-09. Accounts affected: about 1.6M. Domain: actmobile.com.

What happened

In October 2021, security researcher Bob Diachenko discovered an exposed database he attributed to ActMobile, the operators of Dash VPN and FreeVPN. The exposed data included 1.6 million unique email addresses along with IP addresses and password hashes, all of which were subsequently leaked on a popular hacking forum. Although usage of the service was verified by HIBP subscribers, ActMobile denied the data was sourced from them and the breach has subsequently been flagged as "unverified".

What was exposed

  • Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
  • IP addresses: The network addresses your devices used when you signed up, logged in or posted, recorded by almost every website in its access logs.
