On February 23, Cloudflare announced a bug that caused certain traffic sent through their servers to leak from memory, potentially exposing sensitive data. PacketTotal is a Cloudflare customer and uses their services to keep PacketTotal running smoothly and without interuption.
This means that if you interacted with the PacketTotal website between February 10, 2017 and February 18, 2017, the associated activity could have leaked. However, PacketTotal does not currently allow for users to create user accounts or upload data that will be private to any specific user. This means that information that may have leaked should not result in any additional risk to PacketTotal users as the information is already publicly accessible on the PacketTotal site. Even though we believe there is no actionable risk to previous users, PacketTotal is dedicated to providing transparency into any known security issues identified with our service.
We are continuing to monitor the situation for any updates.
