The Bitcoin virus has just left, and the new computer virus has spread in many countries in Europe.

The new super computer virus is spreading rapidly in many European countries, including Russia, Britain, Ukraine and so on. Airports, banks and large enterprises have been reported to be infected with the virus. This kind of virus is similar to the previous bitcoin virus.

There was a blackmail virus in May, which spread in many countries around the world. The scope of influence covers many fields, such as universities, railway stations, self-service terminals, postal services, gas stations, hospitals, government terminals and so on. This can threaten the security of a country.

The harm brought by the blackmail virus is huge, the scope of the blackmail virus is also very wide, and the losses of the users who are recruited are also very serious. Experts at Cyence, an online risk modeling firm in Silicon Valley, said the global direct cost of the computer crash totaled about $8 billion, according to the Wall Street Journal.

Comparison between Petya and WannaCry virus

1. Encrypted target file type

Petya encrypts fewer file types than WannaCry.

There are 65 file types encrypted by Petya and 178 by WannaCry, but common file types are already included.

2. Pay the ransom

Petya needs to pay $300 and WannaCry needs to pay $600.

Successful users are asked to pay $300 worth of bitcoin within 72 hours. Bitcoin is chosen because it is more difficult to track than traditional payment methods, doubling the ransom for more than 72 hours, and if the ransom is refused after seven days, the computer will be locked forever.

Security patches are relatively simple for individual users. As long as self-study loading, can be completed. But for enterprises or organizations, it is necessary to timely early warning, defense, one-click repair and so on.

Make security patches and use genuine Windows software to avoid fishing nets and fishing software.
