Lapsus is a hacker group that has hacked Nvidia, Samsung, and Microsoft. The hacking group posted a file that contains partial source code for Bing and Cortana in an archive holding nearly 37GB of data.
Microsoft confirmed that DEV-0537 compromised “a single account” and stole parts of source code for some of its products. Microsoft investigators have been tracking the hackers’ group for weeks and detail some of the methods they’ve used to compromise victims’ systems.
The group says it’s had access to data from Okta, Samsung, and Ubisoft, Nvidia and Microsoft. The companies like Samsung and Nvidia have admitted their data was stolen, Okta pushed back against the group’s claims that it has access to its authentication service. The Okta service has not been breached and remains fully operational.
