On May 12, 2017, the WannaCry blackmail virus can be said to be a nightmare for users around the world: infrastructure, schools, communities, enterprises and personal computers in more than 150 countries have been severely damaged, which has seriously affected people's lives, work and study, as well as huge property losses.

The virus mainly takes advantage of Windows system vulnerabilities to gain the ability of automatic transmission and can infect all computers in the system in just a few hours. When the blackmail virus appears on the user's host system, a blackmail dialog box pops up to indicate the purpose of the extortion and ask the user for bitcoin.

Since the outbreak of wannacry around the world, various extortion viruses and their variants have emerged one after another, and "loophole" and "blackmail" have become sensitive words to change the color of the conversation. In the face of an endless stream of blackmail viruses, how can we ensure data security?

1. Data backup

As early as after the outbreak of the blackmail virus, some companies said that they backed up the data through the data backup all-in-one machine, but failed to ensure data security, and the backup data was still infected by the virus. Therefore, here, the editor provides you with some synchronous backup network disks with high security level, such as Dropbox, Lenovo network disk, radium cloud disk and so on. These network disks can help you back up important data to the cloud.

two。 Update in time

Upgrade the operating system to the latest version in time, turn on the automatic update function of the system, update and install it in time. Firmly stop using all operating systems that are old or no longer provide updated features.

3. Do not open unknown links at will

Raise awareness of security, do not easily open strange links, e-mails and other forms of unknown links, do not download unsecured software and files at will.

With the emergence of extortion virus, the forms of this kind of blackmail virus are becoming more and more diversified, which not only brings new challenges to network security, but also increases people's attention to network security. Therefore, in order to avoid being infected with blackmail virus again, we should improve the awareness of network security in our daily life, update and back up the data in a timely manner.
