Cybersecurity: Threats and Defences: CERT Polska finds Zimbra flaw under attackBackground
CERT Polska is Poland's national computer emergency response team and operates as CSIRT NASK within the country's cybersecurity system. It tracks malicious activity, analyses vulnerabilities and incidents, publishes warnings and helps organisations respond to cyber threats. Its national role makes it a bridge between technical researchers, Polish network operators and public authorities.
The team also shares findings with response organisations abroad. Its vulnerability research can support vendor fixes and alerts from other national cyber centres, extending a Polish investigation into wider defensive guidance. CERT Polska's public material serves administrators who need technical detail as well as organisations deciding how urgently to act. It coordinates and advises; the owners of affected systems remain responsible for applying updates, reviewing logs and containing an incident.
