A significant data breach at SiSense, a business intelligence platform, was reported after unauthorized actors allegedly compromised the network and exfiltrated data, potentially including customer data. The US government, through agencies like @CISAgov and independent security researchers, has responded to the incident. Customers are highly recommended to change passwords of their SiSense accounts. The breach, as reported by TechCrunch and highlighted by @ajvicens and @timstarks, raises concerns over a potential supply chain attack affecting SiSense's customers.
