CISA Recommends Segmentation & Zero Trust To Combat Interlock Ransomware
Akamai Technologies, Thursday, July 24th, 2025
On July 22, 2025, the Cybersecurity and Infrastructure Security Agency (CISA), along with the Federal Bureau of Investigation (FBI) and the Multi-State Information Sharing and Analysis Center (MS-ISAC), issued a cybersecurity advisory that warns organizations about a new ransomware variant known as Interlock.
This human-operated ransomware is known for stealing and encrypting sensitive data, often followed by extortion demands. And like many modern ransomware campaigns, its success hinges on one key factor - lateral movement.
Segmentation is a critical step
Among its recommendations, CISA includes segmentation, one of the most effective defenses against these attacks.
Segmenting your network isn't just good advice. It's a critical step for organizations that are looking to defend against sophisticated, targeted ransomware attacks like Interlock.
