Maze Ransomware Attacks: Security Perspectives

John Shier, senior security advisor, Sophos

Multiple security software firms have been tracking Maze ransomware attacks. In a statement to MSSP Alert,  John Shier, senior security advisor, Sophos, noted:

“The ransomware attack on Canon is yet another example of the Maze gang’s sustained and brazen targeting of enterprises. Following other recent high-profile attacks, this latest salvo should be a wake-up call to all the enterprises who haven’t taken the time to assess their security posture and bolster their defenses against these pernicious adversaries.

Many of these attacks start by exploiting external services or simple phishing campaigns. The successful campaigns will often be followed by living-off-the-land techniques, abusing over-privileged and under-protected accounts, and hiding in plain sight.

Enterprises must take the time to ensure they’ve built a strong security foundation (e.g. principle of least privilege, MFA everywhere, patching, user training, etc.), which includes investment in both prevention and detection technologies today if they don’t want to be a victim tomorrow.”
