Cyberattack again Jolts the World, the perpetrators ask for 300 Bitcoin

Within a month and a half, many countries around the world have once again been hit by the cyber attack. This dangerous virus has affected many servers in Russia, the UK, Europe and the USA, while damaging Ukraine to the maximum.
It is widely believed that this virus is even more dangerous than the previous 'Vanakrai' Ransumware. India is also said to be hit by this virus. However, Gulshan Rai, chief of the Indian Cyber Security Agency, has denied any kind of complaint.

Ukraine has been the Hardest Hit
IT experts have identified this virus as 'Golden-Eye' or 'Patwrap'. This is an advanced form of 'petya' virus that came out last year. Its worst effect is coming in Ukraine. There is a big malfunction in the government ministries, power companies and the computer system of the bank. 

Ukraine's Central Bank, the government power distributor company Ukrainergo, the aircraft maker Antononov and two postal services were severely affected. Payment cards are not working in the metro of the capital Kiev. Many petrol pump stations have had to stop their work.

Apart from Russia's Rosneft Petroleum Company, Denmark's Maritime Traffic Company, Maysk, UK veteran advertising company WPP, French company St-Gobain and America's veterinary pharmaceutical company, Merc and Company, have also complained of being influenced by their servers.

Prime Minister Vladimir Volodymyr Grosman of Ukraine gave information about cyber attack through Facebook. However, he also said that his key systems were not affected by this attack. The first complaint of cyber attacks came from the banks of Ukraine. This attack is reminiscent of the 'Vanakrai RainSwitch' cyber attack in May last month. This virus affected more than 2 million people in more than 150 countries.

France also Bears the Brunt
The French company St Gobain, who owns the constructions, has also made such complaints. The deputy prime minister of Ukraine has put a picture on Twitter, in which the system is experiencing a malfunction. He wrote in the caption, "Ta-da! The network is down in the Secretariat of the cabinet minister."

What is the Petya or petrawap?
According to Surrey University professor Alan Woodward, this ransomware first appeared in the beginning of 2016. In this, the criminals not only encrypt all the files, but they attack a portion of the operating system, which is called Master File Table (MFT). For MFT systems, it is important to know where to find files on a computer. If there is hindrance, then all the files are locked.

Demand for $ 300 Bitcoin Ransom
According to a media company in Ukraine, cyber attackers have demanded $ 300 BitCoins to reload the system files. In America, the cost of a Bitcoin is approximately $ 1710.

Takes advantage of weakness like Vanakrai
Cyber experts have warned that this virus spreads very fast and no person is needed for it. They believed that this time cyber-attackers took advantage of the same deficiency, which was raised in the 'Vanakrai' attack.

These messages were shown on computer screens
'Oops, your important files have been encrypted (locked). If you are seeing this message, then you cannot open your files because they have been locked. May be you are looking for a way to open it, but do not waste your time. Nobody can open it without our services. For this, you have to send $ 300 Bit Coins to the address given below. '

More Dangerous than the previous virus
- Locking the entire hard disk at once instead of locking one file.
- Without this external help, this virus automatically gets from one machine to another machine.

How Does Ransomware Attack
RanSamware locks the data as 'encrypt' by entering into the system. For this reason, the user can not access the data till he returns to Ransom. This virus spreads via email.

Avoid these ways
- Keep an anti-virus program and operating system updated in the computer.
-Don't open an email from an unknown source. Do not click on attachments and links sent from this mail.

- Create a strong password
Backup them at regular intervals to keep files and folders in your computer safe. Keep backups on an external hard disk or server.
Beginning in America
The first case of RanSamware came out in the US in 2005.
