Malaysia's Ministry of Health (MOH) temporarily took down its official website on June 30, 2026, following a cyberattack that defaced the homepage with a message signed "MUSHR00W" and symbols linked to the hacker group Anonymous [1].
The disruption was first noticed on June 27 when users experienced access problems, which were later linked to the cybersecurity incident [2, 3]. The MOH website is used solely for corporate and public information and does not store patient medical or personal health data, according to officials [2, 3, 1].
Authorities confirmed that critical MOH systems were not affected by the breach. The ministry stated, "So far, there is no indication that the incident has affected critical systems or resulted in any breach of sensitive MOH data," ensuring the public that patient records remain secure [2].
Healthcare delivery systems under MOH continue normal operations, safeguarded by separate infrastructure with strict cybersecurity controls [2, 3, 1]. The ministry emphasized its commitment to maintaining the security of its digital assets and the continuity of healthcare services for the public [3].
MOH is working with relevant agencies to investigate and address the incident. Officials pledged to provide further updates as the investigation progresses [2, 3, 1]. The website remains offline temporarily as enhanced cybersecurity measures are implemented [2, 3, 1].
