The latest investigation progress of the well-known aristocratic private school "Cambridge International School" Linkou campus was blackmailed by hackers. The police obtained the original threatening letters received by the school and parents for digital identification, and traced the source IP of the letters, which showed that they were from England. The police have determined that the hackers probably only mounted a VPN virtual private network to cover up the real address. There is a high probability that it was done by an overseas group, and it is currently confirmed that only the Linkou campus was affected. The police admitted that the difficulty of solving the case is "very high."

It is reported that the police task force analyzed the original file of the threatening letter and found that although the sending node was located in England, this was not because the other party had superb concealment technology, but simply used a VPN springboard to obscure the real IP. Since the hackers accurately grasped the school system and parents' personal information, the police did not rule out that malicious programs had been implanted in the system before. After obtaining the information, they used a VPN to send extortion letters across the country.

At present, the police have compiled relevant digital evidence and are trying to trace the true source through channels. However, the police admitted that it has long been a common method for overseas hackers to use VPN springboards to commit crimes. In addition, the cross-border data retrieval procedures are cumbersome and often have frequent interruptions. It is indeed difficult to follow the clues to identify the person behind the scenes and arrest the case.
