Enable protected files in the Windows Operating System to prevent unauthorized changes.Use a host-based firewall and restrict server message block (SMB) connections to a limited number of administrator machines.Remove unnecessary access to administrative shares, especially ADMIN$ and C$.

You also shouldn’t wait for an attack to start before implementing security improvements and cybersecurity monitoring. Paying ransoms isn’t the solution.As the FBI notes, payment doesn’t guarantee your data won’t be leaked or that you won’t be attacked again.
ATENTO RANSOMWARE SERIES
It’s an involved series of steps to be sure, but if you know what to look for, you can detect ransomware in progress, hopefully stopping it before it takes hold. Encrypts data saved to any local or remote device (excluding core system functions).Change the local registry to create persistence and a new wallpaper screen.Updates group policy to disable Windows defender.Uses Stealbit application to exfiltrate specific file types.Detects data storage: local, remote shares, external storage devices.Determine hostname, host configuration, domain information.Detect and delete shadow copies on the disk that might enable restoration.Detect and delete application, security and system log files.Checks for Eastern European languages (Russian, etc.).The FBI notes that this ransomware begins to take the following series of steps: Though it’s a bit complex, it’s also fairly predictable. When the next generation LockBit 2.0 ransomware begins an attack, it uses bitwise operations to evade detection while it decodes strings and loads modules.
No matter how an attack ends up, significant expenses for investigation, remediation, business losses, and reputation damage tend to follow.
This new act also allows law enforcement to further punish companies for negligence – perhaps even more than the $500K imposed upon CafePress for their failures. What’s important to note here, is that with the newly signed Strengthening American Cybersecurity Act (SACA), companies in critical infrastructure must now report cyberattacks to CISA within 72 hours.Īnd, according to SACA, any ransomware payments must be reported within 24 hours, drastically increasing the pressure during an attack. The Lockbit gang operates ransomware as a service, recently striking the world-wide IT consulting firm Accenture, and demanding $50 million in ransom.Ī second Lockbit victim, Atento, disclosed that even without paying a ransom, it still suffered nearly $35 million in business losses and over $7 million in expenses from an attack affecting only their Brazilian operations.Īnother major ransomware gang, Ragnar Locker, struck at least 52 identified entities in 10 critical infrastructure segments.
