Texas-based cybersecurity vendor Praetorian has launched a new machine learning-based secrets scanner, called Nosey Parker, onto its Chariot Platform, which provides attack surface management and offensive security managed services.\u00a0Nosey Parker is a machine learning-based service developed using the regular expression (regex) pattern matching technique to detect sensitive secrets like passwords, API keys, access tokens, asymmetric private keys, client secrets and credentials left inadvertently in source code and configuration files.\u00a0How Nosey Parker works\u00a0Pattern matching with regular expressions involves scanning for secrets that follow distinct and identifiable patterns. Examples include keys with certain prefixes or of a fixed length. \u00a0\u201cTraditional secrets scanners are noisy, either suffering from a very high number of false positives or handling custom secret types poorly,\u201d says Richard Ford, CTO at Praetorian.\u00a0When compared to existing regex scanners, Praetorian aims to provide a more\u00a0extensive secret patterns list, faster matching, multiple lines pattern matching, and the ability to deduplicate findings.The regex scanner has been trained using a dataset of roughly 7,300 public repository scans from GitHub, consisting of 16 million distinct binary large objects (or blobs), yielding 15,000 matches with an 82% precision rate, according to Praetorian.\u00a0\u00a0\u201cOur ML-powered scanner uses neural networks to pull context around the files we\u2019re scanning. This translates to a scanner that is both low noise and doesn\u2019t need to be customized around new secret types,\u201d says Ford. \u00a0\u201cI think that Praetorian is certainly heading in the right direction,\u201d says Chris Steffen, information security research director at Enterprise Management Associates. \u201cManaged security service providers are clamoring for these kinds of dev and automation tools that drastically improve security, address regulatory and vendor due diligence requirements, and scale to meet customer demands.\u201dNosey Parker will initially be available to Chariot customers, with plans to launch a standalone scanner tool shortly.
