    The National Institute of Standards and Technology (NIST) has announced that a new post-quantum cryptographic standard will replace current public-key cryptography, which is vulnerable to quantum-based attacks. Note: the term “post-quantum cryptography” is often referred to as “quantum-resistant cryptography” and includes, “cryptographic algorithms or methods that are assessed not to be specifically vulnerable to attack by either a CRQC [cryptanalytically relevant quantum computer] or classical computer.” (See the National Security Memorandum on Promoting United States Leadership in Quantum Computing While Mitigating Risks to Vulnerable Cryptographic Systems for more information).

  • Understanding and Preventing Dependency Confusion - FOSSA

    Dependency confusion is a software supply chain exploit that takes advantage of a quirk in certain package managers to inject unwanted (and potentially malicious) code. These attacks are based on the fact that many package managers check public code registries for a package before private registries. Accordingly, if a package exists in a private registry, an attacker could register a package of the same name with the public registry. Then, when a new install occurs, the malicious version on the public registry would be pulled in.
