Simulating Vulnerabilities

The national digital college entrance examination cheating prevention system has been running smoothly for several years and is regarded by everyone as impregnable and invulnerable. No one knows that under this seemingly perfect protection system, there are hidden vulnerabilities left over from years of iteration. Subtle data deviations have been ignored for many years, and black gaps for traceless cheating quietly exist. Once exploited by black market hacker groups, the fairness of the college entrance examination will completely collapse in several years. Lin Chen, a technician at the Education Examination Institute, is paranoid, rigorous, and extremely sensitive to code vulnerabilities. During a routine inspection, he captured traces of abnormalities hidden in the system. Under the pressure of doubts and incomprehension from all members, Lin Chen launched a full-power virtual simulation test, using a 1:1 replica of the real college entrance examination scene, reverse deduction from the perspective of cheaters and hackers, and uncovered the underlying bugs of the system layer by layer. Secret and traceless data tampering, blind spots in monitoring and identification, paralysis of system risk control under high pressure, secret intrusion and obstruction by black market hackers... Countless fatal vulnerabilities have surfaced one after another. On one side is the intense network attack and defense duel, on the other side is the system repair project of repeated trial and error and difficult reconstruction. Use code as an edge and technology as a shield. Outside the ordinary examination room, on the unknown virtual battlefield, technician Lin Chen fought fiercely to the end, blocking all cheating loopholes one by one, iteratively upgrading the national examination risk control system, using extreme professionalism and persistence to cut off the black chain of cheating, and defend the most precious college entrance examination fairness for millions of candidates!
