An active and persistent phishing campaign, codenamed VENOMOUS#HELPER, has been observed since 2025 and continues to pose a significant threat in 2026 and beyond. This campaign targets organisations by using legitimate Remote Monitoring and Management (RMM) software, such as SimpleHelp and ScreenConnect, to establish persistent remote access to compromised systems. With over 80 organisations already impacted, predominantly in the U.S., the need for a robust cybersecurity strategy has never been more pressing for businesses in Portugal and globally.
The Rationale Behind This Persistent Threat
The sophistication of the VENOMOUS#HELPER campaign lies in its ability to exploit trust in widely used RMM tools. Attackers do not need to develop complex malware; instead, they abuse legitimate functionalities to gain and maintain control over victims’ systems. This method makes detection more challenging, as malicious activities can be masked as normal IT operations.
Exploiting Legitimate Tools
By utilising software like SimpleHelp and ScreenConnect, cybercriminals can bypass many traditional defences. These tools are designed to allow remote access and system management, which, in the wrong hands, becomes a gateway for data exfiltration, ransomware deployment, or other malicious activities. Persistence is ensured by installing RMM agents that allow continuous access, even after initial detection.
The Critical Impact on Businesses
Compromise through phishing attacks exploiting RMM tools can have devastating consequences for any business, regardless of its size or sector.
Data Loss and Operational Disruption
Unauthorised access to systems can lead to the loss or theft of sensitive data, including customer information, intellectual property, and financial data. Furthermore, the interruption of business operations due to ransomware attacks or the need to remediate compromised systems results in significant financial losses and reputational damage. Rapid response capability is crucial to minimise these impacts.
Compromising Trust and Compliance
A cybersecurity incident not only affects technological infrastructure but also erodes the trust of clients and partners. Businesses face the risk of heavy fines for non-compliance with data protection regulations, such as GDPR, and the necessity to report data breaches, which can tarnish brand image in the long term.
