Ransom virus is a kind of malicious software, which encrypts or locks the victim's computer or mobile phone system and requires the victim to pay ransom to unlock it. Before paying, users will not be able to use files or applications on infected devices, and the severity can be imagined. Here are some tips for dealing with ransomware attacks.
First, backup is very important. Have multiple backups (such as cloud, external hard disk, etc.). ) can reduce the loss caused by ransomware. If you find that your device is infected, don't pay the ransom, because no one can guarantee that the virus author will actually decrypt your file. Instead, try to restore data from a backup or other device. In more serious cases, if the data cannot be recovered, you can consider calling the police or consulting a network security expert.
Secondly, the cultivation of safety awareness is also very important. Blackmail viruses may spread through e-mail, short messages, social media and other channels, many of which come from social engineering attacks, that is, "social engineering refers to the use of technology, psychology and human habits to induce people to trust and comply with the attacker's request. Therefore, in order to prevent the attack of ransomware, users should understand the security prevention skills and technologies and apply them to real life and work.
Finally, updating the operating system and applications regularly is also a necessary means to prevent and deal with ransomware attacks. Many ransomware exploits unpatched vulnerabilities to invade devices, and the latest security patches help reduce malicious attacks. In addition, keeping the killing software up-to-date is also one of the important security measures.
To sum up, ransomware attacks usually hit innocent victims, so in our daily life, we should be wary of unusual links, letters or information. Then back up the data regularly, conduct safety awareness training, update the system and procedures regularly, and keep the equipment safe.
