UnverifiedTraditional security measures such as code audits, static analysis, and hash verification are ineffective at detecting threats from trusting-trust attacks.76% similarUnverifiedIn the field of software supply chain security, signatures only solve the two problems of "trustworthy origin" and "content not tampered with", and do not guarantee that the code itself is harmless.73% similarUnverifiedThe transparency of open-source models is a prerequisite for security auditing, while the risks of closed-source systems cannot be examined by outside parties.72% similarUnverifiedThe core of the trusting-trust attack is to cause a compromised compiler to re-inject malicious logic when compiling itself, so that even if the source code is clean, the compiled compiler still contains a backdoor.72% similarUnverifiedThere have been real cases of development toolchains being poisoned and then attacking developer keys, and a security check on a single call cannot capture data flows across days and across sessions.72% similar
