Ashlee Benge from ReversingLabs discussing their research titled "Operation Brainleeches: Malicious npm packages fuel supply chain and phishing attacks." Researchers recently discovered over a dozen malicious packages published to the npm open source repository. These packages are targeting Microsoft 365 users and appear to target application end users while also supporting email phishing campaigns.

Research supports that the malicious campaign encompassed more than a dozen files designed to steal sensitive user credentials. The research states "This most recent campaign caught our attention because of a number of features and characteristics in related npm packages that correlate with malicious intent."
