System and method for identifying compromised private keys

Abstract

A computer-implemented method for identifying private keys that have been compromised may include (1) identifying a private key that enables a signatory to digitally sign applications, (2) collecting information about the private key from at least one public source, (3) determining, based on the information collected from the public source, that the private key has been compromised and is accessible to unauthorized signatories, and (4) performing a security action in response to determining that the private key has been compromised and is accessible to the unauthorized signatories. Various other methods, systems, and computer-readable media are also disclosed.

Description

Background technique [0001] In the early days of computing, new applications were often installed via physical disks, making it difficult for malicious agents to impersonate legitimate developers. Applications are now commonly downloaded via the Internet from a variety of sources, including websites and application distribution platforms. Unfortunately, fraudulent websites and malicious developers can easily impersonate legitimate developers and applications, potentially causing users to download malicious applications, posing a significant risk to the security of users, systems, and businesses. [0002] Digital signatures are often used to ensure that applications originate from legitimate and trusted developers and not from potentially malicious impersonators. Unfortunately, the trustworthiness of a digital signature is directly proportional to the security of the private key used to generate it. For example, if a private key has been compromised, a malicious agent could u...
