SINGAPORE: Following a recent hack of the Ministry of Education (MOE)’s Mobile Guardian app, which affected 13,000 students, a Redditor revealed on social media that he had emailed MOE about potential security vulnerabilities as early as two months ago.In a Reddit post dated August 5, the user shared the content of the email, noting his long-standing awareness of the app’s security issues and the potential consequences."So many emails to Mobile Guardian and MOE later, it is disappointing for me to find out that everything I did was for nothing. It still took MOE an actual cybersecurity breach to learn their lesson," the user wrote.The user expressed a desire to raise awareness about the issue by sharing his correspondence with MOE."Hopefully, this will allow us to take similar incidents more seriously in future."Gutzy has reached out to MOE and Mr Chan Chun Sing, Minister of Education for their response regarding this claim and will include their response if received.
Redditor alerts critical vulnerability in the Mobile Guardian App
In the email shared by Reddit user "Hopeful_Chocolate080," the Redditor described a critical vulnerability in the Mobile Guardian app, which was sent to MOE in late May.The email highlighted that the vulnerability involved improper access control, allowing unauthorized read and modification of all data within the Mobile Guardian system. The Redditor noted that this flaw could be exploited in under three minutes.The Redditor suspected that this portal was Mobile Guardian’s internal management system, which, contrary to the information published by MOE, provided full read-and-write access to all schools and users.This included the ability to impersonate users, meaning an attacker could perform any action that school admins could, such as resetting personal learning devices.The Redditor emphasized that this was a trivial vulnerability, likely indicative of other similar issues.The email urged MOE to reconsider Mobile Guardian as a vendor for DMA services, questioning the security and management of sensitive data by foreign companies under contractual obligations.
In an email dated 6 June, the Redditor received a brief reply from MOE, stating that they had raised the issue with Mobile Guardian and were reassessing their cybersecurity posture.
About three weeks later, the Redditor had to write to MOE again to request an update. In their response, MOE stated that they had reviewed the vulnerability report and "confirmed that it is no longer a concern.""However, we take data protection seriously and appreciate all vulnerability disclosures. ""Due to commercial sensitivity, we are unable to share information about our future engagements with Mobile Guardian. We appreciate your understanding. "
Recently, following the loss of internet access issue involving the Mobile Guardian app, the Redditor sent another email to the MOE Minister.The Redditor reiterated his belief that Mobile Guardian should be removed immediately to prevent further damage, even if no replacement is available at present.The Redditor expressed pessimism about the situation, noting that he had not yet received a reply from MOE and doubted his efforts contributed to the app's removal.He also voiced disappointment over the cybersecurity breach on 4 August, criticizing it as a demonstration of Singapore's digital defence failure."It is ridiculous how so many students on the ground knew about the vulnerability and tried to alert the authorities, but nobody took it seriously.""I cannot help but to be reminded of the attempted assassination of Donald Trump — there is just so much similarity between the two incidents. We have got to do much better than this, Singapore."I alerted MOE of an impending cybersecurity attack on Mobile Guardian two months agobyu/Hopeful_Chocolate080 inSGExams
