lapsus$

According to ransomware.live, Lapsus$ is an internationally composed data extortion group most active from mid-2021 through 2022, executing high-profile breaches against Microsoft, Nvidia, Samsung, Okta, and Uber by stealing source code and threatening leaks rather than encrypting files; several members — predominantly teenagers — were arrested in the UK.
