Priority (0–325)
The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

Exploit maturity
An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.
Read in glossary- no public PoC known
KEV status
The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

Classification under NIS2 and CRA
Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.
NIS2
NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.
Read in glossary- Handle the vulnerability in regular vulnerability handling under Art. 21(2)(e) NIS2.
CRA
The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.
Read in glossary- From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.
ISO/IEC 27001
ISO/IEC 27001 is the internationally leading standard for an information security management system (ISMS). It describes a risk-based, process-oriented framework to systematically plan, implement, review and improve information security.

Description
There have been reports of threat actors using a social engineering technique known as ClickFix to trick potential victims into executing malicious commands. Background There have been reports of threat actors using a social engineering technique known as ClickFix to trick potential victims into executing malicious commands under the pretense of providing “quick fixes” for common computer issues. ClickFix has reportedly targeted organisations across a broad range of sectors, including the technology, financial services, manufacturing, wholesale and retail, government, professional and legal services, utilities and energy. This current campaign is targeting the hospitality sector. What is ClickFix? ClickFix is a relatively new social engineering technique increasingly used by threat actors in their campaign. This technique misleads targeted users into applying supposed “quick fixes” for common computer issues, such as performance issues, missing drivers or pop-up errors. Since it's initial reports in 2024, ClickFix has resulted in multiple malware distribution campaigns involving compromised websites, malicious distribution infrastructure and e-mail phishing. Tactics, Techniques and Procedures (TTPs) The ClickFix technique relies on clipboard hijacking, where malicious software secretly intercepts and modifies information that victims copy and paste on their devices. It typically uses dialogue boxes or a fake Blue Screen of Death (BSoD) containing fake error messages to trick victims into copying malicious script or commands on their own clipboards using ClickFix inject before providing instructions to paste and run the malicious content. In recent months, threat actors have also been observed to use phishing emails redirecting victims to their intended webpage. After completing a CAPTCHA challenge, a fake Blue Screen of Death (BSoD) pops up with instructions for the victim. An example of a ClickFix campaign pop-up message is shown in Annex A and B. The victims typically follow a three-step process that enables the execution of malicious PowerShell commands: Open a Windows Run dialog box Automatically or manually copy and paste a malicious PowerShell command into the terminal [press 'CTRL+V'] And run the prompt [press ‘Enter’] Because the ClickFix technique relies on users pasting the content, this is sometimes referred to as “pastejacking.” Threat actors often use the ClickFix technique as an initial infection vector to deploy malicious payloads such as infostealers, remote access trojans (RATs) or disable existing security tools. This delivery method bypasses many standard detection and prevention controls, as the attack does not depend on any exploit, attachment or malicious link. Instead, potential victims unknowingly run the malicious command themselves, through a trusted system shell. This method makes infections from ClickFix more difficult to detect than drive-by downloads or traditional malware droppers. Impact Successful execution of the ClickFix technique can lead to the deployment of various malware families, including the DCRAT, NetSupport RAT, Latrodectus, and Lumma Stealer, resulting in credential theft, data exfiltration, email account compromise, and potential ransomware incidents. Threat actors can utilise their access to compromised systems to drop secondary payloads, perform privilege escalation and move laterally across other systems within the network. How to Protect Your Organisations Organisations are advised to adopt the following mitigation measures to safeguard against the ClickFix Campaign: Remain vigilant against fake “CAPTCHA” or “Fix It” prompts and recognise the tell-tale signs (e.g. unexpected run-dialog instructions or unofficial BSoDs) of the ClickFix campaign. Remain vigilant against other attack vectors that could be chained to redirect users to the ClickFix site (eg: phishing emails) Update your systems, applications and software to the latest versions and use an up-to-date anti-virus software to detect malware and malicious phishing links. Implement Security Information and Event Management (SIEM) solutions to perform logging, asset visibility, and continuous system monitoring to detect anomalous network connections and malicious PowerShell commands. Enforce strict access control policies, ensuring users and systems only have the minimum permissions necessary. This limits the impact of a successful compromise by preventing privilege escalation and lateral movement. Implement application whitelisting to allow only approved software and scripts to execute, effectively blocking unknown executables and malicious PowerShell scripts typically used in ClickFix campaigns. Administrators may wish to consider tracking and blocking the Indicators of Compromise (IOCs) associated with the ClickFix campaign.
