Singapore launched its largest coordinated cyber defense operation, Operation Cyber Guardian, after a highly targeted attack affected all four major telecommunications operators: M1, Singtel, StarHub, and Simba. The assault was attributed to UNC3886, which exploited a zero-day vulnerability and accessed a small number of critical systems but was contained by government and telco responders with no evidence so far of stolen customer data. #UNC3886 #OperationCyberGuardian
