The Cl0p Ransomware Group has confirmed its involvement in the recent Cleo attack, naming Blue Yonder as one of its victims.
The group has announced plans to reveal over 60 additional victim organizations unless ransom demands are met, says securityweek.com.
This alarming development shows the increasing risks posed by ransomware groups targeting critical vulnerabilities in enterprise software.
Key Takeaway to Cl0p Ransomware Group
- Cl0p Ransomware Group has targeted over 60 organizations through vulnerabilities in Cleo’s file transfer tools, posing a significant threat to global cybersecurity.
The Cl0p Ransomware Group and the Cleo Attack: What You Need to Know
The Cl0p Ransomware Group, known for high-profile cyberattacks, has taken credit for exploiting vulnerabilities in Cleo’s file transfer products.
This latest campaign, which began in December, demonstrates the group’s ability to compromise sensitive data by exploiting weak points in widely used enterprise software.
Here’s a detailed breakdown of the situation:
Who Are the Targets?
So far, Cl0p has publicly named Blue Yonder, a supply chain management software provider, as a victim. They claim to have impacted over 60 other organizations, many of which reportedly ignored initial ransom demands.
According to Cl0p’s statement, the full names of these companies will be revealed if they do not comply by December 30, 2024.
What Was Exploited?
The group exploited vulnerabilities in Cleo’s Harmony, VLTrader, and LexiCom file transfer tools. These vulnerabilities, tracked as CVE-2024-50623 and CVE-2024-55956, allowed attackers to steal files from affected systems.
Notably, CVE-2024-55956 was exploited as a zero-day vulnerability, enabling attackers to strike before a patch was released.
| Vulnerability | Description | Impact |
|---|---|---|
| CVE-2024-50623 | Weak authentication controls in Cleo products | Unauthorized file access |
| CVE-2024-55956 | Zero-day vulnerability enabling unauthenticated file theft | Immediate data exfiltration risk |
Impacted Organizations and Data
The stolen data includes sensitive information such as source code, encryption keys, configuration files, and other proprietary data. Blue Yonder’s breach reportedly affected major clients like Starbucks and prominent grocery store chains.
The Cl0p Ransomware Group’s tactics mirror their previous MOVEit campaign, where thousands of organizations were impacted through similar exploits.
The Connection Between Cl0p and Termite
Adding to the complexity of the Cleo attack, another ransomware group, Termite, has claimed responsibility for the Blue Yonder breach.
This raises suspicions of a possible collaboration or overlap between Cl0p and Termite, further complicating attribution efforts.
These connections emphasize the need for robust attribution mechanisms in combating ransomware.
Why This Matters
Cleo, a leading enterprise software developer with over 4,000 clients, is a critical player in the data transfer space.
The exploitation of its vulnerabilities underscores the far-reaching implications of ransomware attacks on supply chains, finance, and public sectors.
Historical Context: The MOVEit Campaign
Cl0p’s involvement in the MOVEit campaign earlier in 2024 provides insight into its modus operandi.
In that attack, a zero-day vulnerability in MOVEit’s file transfer software led to data theft from numerous organizations.
About Cl0p Ransomware Group

Rounding Up
The Cl0p Ransomware Group’s latest campaign demonstrates the escalating threats posed by ransomware gangs exploiting enterprise vulnerabilities. By targeting Cleo’s widely used software, Cl0p has disrupted multiple organizations, demanding urgent cybersecurity measures across industries.
The need for proactive vulnerability management and strong incident response plans has never been more critical.
As companies face rising cybersecurity challenges, collaboration between public and private sectors will be key to mitigating these threats.
