The posted archive contains internal data on Microsoft’s Bing search engine and the voice assistant software Cortana, according to the LAPSUS$ hacking group.
The cybercriminal group that claims to have breached Microsoft has started to dump files allegedly taken from the hack. On Monday, the LAPSUS$ gang began circulating a 10GB compressed archive that supposedly contains internal data on Microsoft’s Bing search engine and Bing Maps, along with the source code to the company’s voice assistant software Cortana. “Bing Map is 90% complete dump. Bing and Cortana around 45%,” LAPSUS$ said in a post in the group’s public chatroom. According to BleepingComputer, the archive expands to 37GB once it’s been uncompressed, and contains the source code to over 250 projects that appear to belong to Microsoft.
