Alert: as sent by MalwareBytes.
Earlier this morning, many businesses around the world were hit by a new Petya-esque ransomware attack. Tens of thousands of infections have been reported globally, just one month after the WanaCrypt0r outbreak.
Malwarebytes are alerting about this outbreak. If you’re using traditional signature-based security, you are at risk. Malwarebytes customers were protected against this specific ransomware variant. Our anti-ransomware technology uses a dedicated real-time detection and blocking engine that continuously monitors for ransomware behaviors, like those seen Petya-esque. We can do this because Malwarebytes has the best-informed telemetry powered by intelligence from millions of users.
This Petya-esque ransomware is more powerful, professional, and dangerous than last month’s WanaCrypt0r attack and uses the same EternalBlue exploit to target vulnerabilities in Microsoft’s operating system. However, this ransomware utilizes an MBR (Master Boot Record) locker, which prevents the computer from rebooting. The attack can spread laterally, infecting multiple systems within the organization. It does not have a kill switch like WanaCrypt0r, so there’s no simple end to the outbreak.
Ensure you are protected by installing MalwareBytes.
