How many ways do U.S. businesses need to be told to lock down their systems to safeguard themselves from ransomware? That's the focus of a new, joint cybersecurity advisory from the U.S. government pertaining to BlackMatter, following an advisory issued last month about Conti.
The most sought-after type of victim for ransomware-wielding attackers is a large, U.S.-based business with at least $100 million in revenue, not operating in the healthcare or education sector, with remote access available via remote desktop protocol or VPN credentials, threat intelligence firm Kela reports.
The healthcare sector has been reshaped by the forces of digital transformation and virtual health. But it also has been besieged by the shifting threat landscape and the escalation of destructive ransomware attacks. What role can zero trust play? Jack Miller of Menlo Security shares insight.
Security researchers at AT&T Alien Labs say they've discovered a cluster of Linux ELF executables, identified as modifications of the open-source PRISM backdoor, that attackers have been using in several campaigns for more than three years.
