We recommend that you take the following mitigation actions, in case you are using your Mailfence account with any of the affected email clients listed , in order to protect yourself against signature spoofing.
Update your OpenPGP-compatible email client and/or plugin . Researchers have reported their findings and suggested improvements to the developers of affected clients in a process they call “coordinated disclosure.” This is intended to ensure that affected clients can fix the issues before disclosing them to the public.
Disable HTML rendering and Remote Content Loading . Prevent your email client from rendering HTML or loading active content. This will prevent any attempts to spoof signature verification messages armenia whatsapp number data 5 million from working. Please consult your email client's specific documentation on this. E.g.
