The Cl0p Ransomware Gang's Attack on Radius

The Cl0p ransomware gang has attacked Radius. Radius is a software company specializing in providing B2B data and intelligence solutions. The company focuses on helping businesses gain insights into their target markets, identifying potential customers, and improving their marketing and sales efforts through data-driven strategies. Cl0p posted Radius to its data leak site on August 25th but provided no further details.

Background on Cl0p

Cl0p is a RaaS (Ransomware-as-a-Service) platform first observed in 2019. Clop has advanced anti-analysis capabilities and anti-virtual machine analysis to prevent investigations in an emulated environment like those commonly used by security tools. Clop is increasingly using automation to exploit known vulnerabilities to infiltrate targets, as well as a SQL injection zero-day vulnerability (CVE-2023-34362) that installs a web shell – a rarity amongst ransomware operators.

Recent Activities and Tactics

Attacks by Cl0p surged in Q1 of 2023 as the gang leveraged patchable exploits for the GoAnywhere file transfer software to compromise more than 100 victims in a matter of weeks, although it is unknown how well they were able to monetize the attacks. Cl0p is likely to be leveraging automation to identify exposed organizations who have not patched against known vulnerability, which is why we are seeing so many new victims.

Ransom Demands and Trends

Ransom demands vary depending on the target and average around $3 million dollars but have been reported as to be as high as $20 million. Ransom amounts are likely to continue to grow as Clop focuses more on the exfiltration of sensitive data.
