As one of the early units involved in troubleshooting VnDirect's system, Mr. Nguyen Tu Quang - General Director of Bkav Technology Group said that hackers used data encryption attacks, a form of data encryption attack. Attacks are relatively common in recent years in Vietnam and around the world. Specifically, Mr. Quang said hackers use a vulnerability to penetrate the system, then try to install a virus that encrypts data and will use that encryption key to extort money from the victim.
According to cybersecurity expert Vu Ngoc Son, Technology Director of Vietnam National Cyber Security Technology Company (NCS), an important issue is finding and closing the "hole" that hackers have penetrated. VNDirect is a large company with standardized operating procedures. As hackers penetrate deeper into the system, the possibility arises that hackers have attacked using unknown or unpatched security vulnerabilities (zero-day vulnerabilities) in the software.
All systems are vulnerable to Zero day attacks. This vulnerability is not yet known to the manufacturer or software developer, so it is a weakness of all systems. In the world, according to statistics, major attacks are carried out via Zero day. According to Mr. Son, restoring data and services is only the first step. The next important thing is to find the hole that helps hackers penetrate the system and close this hole.
