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
The Singapore Cyber Emergency Response Team (SingCERT) continues to receive reports of scammers impersonating CSA and SingCERT officers. Members of the public are advised to stay vigilant and not follow any instructions given by these scammers. Last Updated: 05 May 2026 Singapore Cyber Emergency Response Team (SingCERT) has received multiple reports of scammers impersonating Cyber Security Agency of Singapore (CSA) and SingCERT officers over phone conversations. These scammers attempt to trick members of the public by providing a fake employee ID and case number, claiming that their phone numbers had been used in illegal activities in Malaysia. Thereafter, the scammers would re-direct them to the "Malaysian Interpol / Police" so that they can lodge a report to deny the recipient's involvement in the alleged illegal activities. Victims are asked to provide details such as their name, NRIC, family information, and social media account details. We are also aware of other similar cases. Members of the public are advised to review the following alerts for more information: Scammers Impersonating CSA, the Singapore Police Force (SPF), and the Ministry of Home Affairs (MHA) : Scammers send fake criminal investigation notices claiming the recipient is involved in cyber‑infiltration and data seizure, then pressure victims to respond within 48 hours to avoid supposed criminal charges. Scammers Impersonating CSA and the SPF : Scammers send fake court orders alleging illegal online activity linked to the recipient’s IP address, then pressure victims to respond within 24 hours to avoid supposed imprisonment. Members of the public should not follow any instructions given by these scammers from any form of communication. This includes: Installing any software or applications on your computers or mobile phones Disclosing any personal or financial details Making transfers or payment for alleged services rendered. Government agencies will never ask you for your confidential details or request for money to be transferred to specific bank accounts. SingCERT officers will never ask you to download and install software or applications to access your computer or mobile phone remotely. When in doubt regarding any caller claiming to represent CSA or SingCERT, you may wish to email us at singcert@csa.gov.sg to verify or report the incident to SingCERT at https://go.gov.sg/singcert-incident-reporting-form . You should always verify the authenticity of unsolicited callers claiming to be from a government agency. This can be done by contacting the agency through official channels (e.g., email addresses and helplines listed on the agency's official website). If you have fallen victim to a scam or incurred any monetary losses, please lodge a police report. You can lodge a report at any neighbourhood police post or online at https://www.police.gov.sg/E-Services/Lodge-Police-Report . We urge you to report scam calls or requests to the police. This information may be used to aid in ongoing investigations or uncover unreported crimes.
