<h1>Singapore battles sophisticated cyberattack on critical infrastructure by alleged China-linked group UNC3886</h1> Singapore's security agencies are combating an ongoing cyberattack on critical infrastructure by UNC3886, an alleged China-linked threat group identified by cybersecurity firm Mandiant. Three cabinet ministers addressed the incident, with the defense minister confirming military units are working with the Cyber Security Agency in a whole-of-government response. The coordinating minister for national security described the group as highly sophisticated and posing serious national security risks. Officials stated the decision to publicly name the attackers was based on assessment that disclosure was appropriate, noting actual attacks far exceed disclosed incidents. The digital development minister emphasized the devastating potential consequences if critical systems like water, power, or telecommunications networks were compromised. China's embassy strongly denied the allegations, calling them groundless accusations, and reiterated opposition to all cyberattacks while expressing readiness to cooperate on cybersecurity matters.
