Evil MinIO Exploits Pose Risks to Corporate Networks

In a recent development, cybersecurity experts at Security Joes have uncovered a looming danger in the realm of network security. An unidentified threat actor is currently exploiting vulnerabilities within the MinIO Object Storage system, creating a new attack vector that could potentially breach corporate networks. This alarming discovery comes with a critical reminder of the importance of safeguarding your digital infrastructure.

The MinIO Vulnerability Exploits

The threat revolves around an exploit code ominously named “Evil_MinIO.” This malevolent code takes advantage of two vulnerabilities, specifically CVE-2023-28434 and CVE-2023-28432, which researchers identified within the MinIO Object Storage system. These vulnerabilities pave the way for malicious actors to remotely execute arbitrary code on vulnerable servers, opening a Pandora’s box of potential threats. MinIO is renowned for its high-performance and distributed object storage capabilities, widely adopted by various organizations for its efficiency. However, its popularity has now inadvertently exposed it to exploitation.

The Attack Methodology

To carry out these insidious attacks, threat actors employ social engineering tactics to manipulate unsuspecting DevOps engineers. These engineers are tricked into updating their MinIO software to a compromised version, unknowingly introducing the vulnerabilities into their systems. Once the vulnerable software is launched, attackers seize the opportunity to implant a backdoor, granting them the ability to initiate remote code execution attacks on the targeted systems. To make matters worse, this backdoor remains undetected, exhibiting zero detection rates even on well-known scanning platforms like Virus Total.

The Far-Reaching Impact

The implications of these vulnerabilities are vast and concerning. Both vulnerabilities are categorized as high-severity issues and affect all MinIO versions released before RELEASE.2023-03-20T20-16-18Z. Shockingly, Security Joes researchers have identified over 50,000 MinIO installations exposed online. This unsettling number underscores the urgency of addressing this threat.

These exploits are versatile and can be deployed against Linux and Windows environments, utilizing specific Downloader Scripts. Consequently, the potential for sensitive information breaches and remote code execution attacks looms large.

Protecting Your Digital Assets

In light of these developments, it’s imperative for organizations to exercise caution and vigilance. While open-source platforms like MinIO offer flexibility and functionality, they also present significant security risks when downloaded from unofficial sources. To shield your digital assets from Evil MinIO exploit attacks, the following precautions are recommended:

Source Verification: Always ensure the authenticity of the sources when installing software, especially open-source platforms. Downloading software from official and reputable channels is crucial to mitigate risks.
Security Updates: Keep your software up to date. Applying available security updates promptly is an effective measure against emerging threats.


As the digital landscape evolves, so do the tactics of threat actors. Vigilance and proactive cybersecurity measures are our best defense against the ever-present danger of exploits like Evil_MinIO. Stay informed, stay secure, and safeguard your corporate networks from potential breaches.
