PGP poisoning attacks refer to the spamming of certificates with a significant number of signatures or certifications. This article  continues to discuss the PGP framework, what is exploited in PGP poisoning attacks, the impact that these attacks could have on security, and suggestions made by researchers as to how such attacks can be mitigated, along with the efforts that have been made by researchers to highlight and address these attacks.
