SingHealth hacker known: Iswaran

The govt has confirmed that they knew the hacker of SingHealth confidential data of its patients. It disclosed that ‘the attacker was skilled and sophisticated, and had the characteristics typical of an advanced persistent threat group, usually state-linked’. The govt has taken appropriate action but would not identify the attacker due to security reasons. Ooooh, why so?
 
Iswaran was quoted in thenewpaper as saying, ‘We want to ensure that all Singaporeans understand that we’ve got nothing to hide here, we want to get to the bottom of it as much as Singaporeans do.’ But the govt would hide the identity of the attacker, at least this is what the govt has done, nothing to hide except for this.
 
Who is the attacker, he used this in singular form, an individual or a single country? Why is it so secretive that the attacker cannot be revealed? He is someone very important that revealing his identity would be very embarrassing? Is he someone we know, we trusted but played out Singapore? Could he be a hired foreign talent still in Singapore that would result in many red faces, or a Singaporean or a new citizen?
 
Or is the attacker a country, a friendly country that we trusted as our good friend but again played us out by screwing our ass? Or is the attacker country our enemy, too big to offend, we are afraid to offend other big country because we dare not punch above our weight? We are a small country and must shut up, no more loudspeaker politics? I think taking such a meek stand would only encourage the offender to continue to hack into our system knowing that we can only blow hot air but unable to fight back, we are afraid.
 
Would it not be better to make it public for all to see who the attacker was, friend or foe, to embarrass them so that they would not dare to create mischief against us again? Remember the time when LKY exposed the Americans for trying to bribe him just to embarrass the Americans to prevent them from thinking that it was ok to do such mischievous act?
 
What is so secretive or embarrassing that the culprit cannot be named? Someone’s identity needs to be protected, the attacker’s identity needs to be protected? Whose interest is being protected by this non disclosure? Is the attacker a minor so cannot be named?
 
Weird! BTH.
 
PS. I agree with many of the comments here that this is not funny but fishy. What is the govt afraid of? No more balls in between the legs?
