What is a Shockwave Virus? What are the hazards?

Shock wave. One. About the "blaster" virus:

Shock wave" (virus Chinese name: shock wave (including many variants).

Virus type: Worm.

Attack targets: Windows NT, Windows 2000, Windows XP, Windows Server 2003, etc.

Transmission route: "Shockwave" is a kind of worm that spreads randomly and destructively by exploiting the RPC (Remote Procedure Call, a communication protocol that a program can use to request a service from a program on another computer on a network) vulnerability in the Windows system. It doesn't need to be disseminated via email (or attachments), it's more subtle and less noticeable.

It uses IP scanning technology to find computers on the network operating on Windows 2000 XP 2003, and once it finds a vulnerable computer, it uses a DCOM (Distributed Object Model, a protocol that enables software components to communicate directly over the network) RPC buffer vulnerability to plant a virus body to control and attack the system.

Symptoms of poisoning:1System resources are strained, and the application runs at an abnormal speed;

2.network slowdowns, "DNS" and "S" services are illegally denied, users are unable to browse the web or send and receive e-mails normally;

3.Copying and pasting operations are not allowed;

and other software cannot operate normally;

5.The system restarts for no reason, or automatically restarts after a "System Shutdown" warning pops up, etc.

Solution: If you are accidentally infected with the virus, you can use the following steps to kill the virus:

1.Close the System Shutdown dialog box.

When the shutdown prompt appears, enter "shutdown -a" in the "Start Running" field to cancel the "System Shutdown" prompt, which ensures that the user has enough time to patch.

Correct answer: The shock wave can squeeze the internal organs of the human body through the hands of the hand, and cause killing and destructive effects on the throwing and impact of objects.

The damage to the human body caused by the bomb** is mainly the debris and shock wave generated when the ** passes.

to act. **Debris is mainly caused by direct damage to the body. For example, the rupture of muscle tissue, bleeding. There are also fractures caused by fragments.

Wait. The lethality of the shock wave is mainly determined by the overpressure of the shock wave and the duration of the shock wave. Shock wave overpressure is the pressure of the shock wave and the air pressure at rest (l atmosphere.

the pressure difference; The duration of the shock wave is the time that the shock wave is overpressurized. For ordinary explosives in the air**, when the shock wave overpressure is atmospheric, it will cause damage to doors and windows and glass breakage; When the overpressure is atmospheric pressure, the roof can be lifted; When the overpressure is 1 atm, the building will collapse.

For the human body, when the shock wave overpressure is atmospheric pressure, the person's eardrum ruptures and the internal organs are injured; When the overpressure is 1 atmosphere, the force acting on the entire torso of the human body can reach 4.5 thousand kilograms, in such a large impact force.

Squeeze down. Severe damage to the internal organs of the human body, especially the rupture of the lungs, liver, spleen, and even death.
