A “large scale” attack is targeting Microsoft Azure developers through malicious npm packages. 

On Wednesday, cybersecurity researchers from JFrog said that hundreds of malicious packages have been identified, created to steal valuable personally identifiable information (PII) from developers. 

According to researchers Andrey Polkovnychenko and Shachar Menashe, the repositories were first detected on March 21 and steadily grew from roughly 50 malicious npm packages to over 200 in a matter of days.

The script is responsible for creating accounts and uploading the npm sets, which include container services, a health bot, testers, and storage packages.

Typosquatting is a form of phishing in which small changes are made to an email address, file, or website address to mimic a legitimate service or content.
