A student in Singapore raised concerns about a significant vulnerability in the Mobile Guardian app weeks before a cyberattack led to the mass-wiping of devices belonging to 13,000 students. The student notified the Ministry of Education (MOE) on May 30, asserting the vulnerability allowed unauthorized 'super admin' access to the system, potentially enabling malicious actions like resetting all personal learning devices. While MOE claimed the issue was addressed before the attack, the student expressed doubts about the effectiveness of the patch and highlighted that such vulnerabilities could suggest the presence of other security flaws. Following the cyberattack on August 4, MOE announced the removal of Mobile Guardian from all devices. The incident has sparked discussions among students and raised questions about the app's security management practices. The student hopes to raise awareness about cybersecurity issues to prevent future incidents.
