In February, Vietnam had 2,094,000 computers infected with viruses

In February, there were 12 websites attacked in Vietnam. Notably among these websites are websites that have been attacked at least once before. In addition, there are 2,094,000 computers infected with the virus and the most spreading virus, Virus W32.CTFMonF.Worm .

In fact, websites that have been exploited by vulnerabilities are easily attacked by hackers again, because hackers have gained a lot of important information about the system of this website. Therefore, the recovery of the consequences if unfortunately being attacked is also very important and must be done thoroughly.

According to BKIS Network Security Center, the website administrator needs to do it after his website is attacked as follows:

1. Separating the hacked system from the network, preventing the hacker from continuing to sabotage during the recovery process.
2. Analyze the logs on the system to find out how hackers can take appropriate precautions.
3. Reconfigure the network and server closely.
4. Check the website source code to patch programming holes.
5. Review the server, in case the hackers have installed webshell (a form of backdoor). If webshell is not detected soon, the server system is vulnerable to attack again even though the vulnerability has been fixed

Also in February, there were 2,094,000 computers infected with the virus and the most spreading virus. Virus W32.CTFMonF.Worm : Infected 64,180 computers primarily via USB. This shows that USB is still the most infectious virus path in Vietnam today.
