On the 12th May 2017 a cyber attack happened by some hackers in Europe and this is one of biggest cyber attack in the history of cyber crime because this kind of attack still not happened in the history of cyber world.
This insanely fast-spreading threat that has already hacked nearly 200,000 Windows PCs over the weekend.
In the first few hours, 200,000 machines were infected. Big organizations such as Renault or the NHS were struck and crippled by the attack.
The attack is believed to be the result of "
RANSOMWARE", a type of malware that been used by computer hackers for many years to capture information, extort money or force people or organisations to behave in certain ways.
Now First get to know that "What is Ransomware"?
Ransomware - This is a kind of malware or in simple words, this is computer virus that has been used by the hackers to steal the important information by the govt. or from any organisation or to hack the bank accounts to capture their money or transfer their money in their account.
Hacker make this malware and do attack on the govt. sites to capture their whole data and then they demands for money to realise captured data.
Who Attacked from Wannacry Ransomware?
This attacked by the Wannacry:- Wannacry is a ransomware computer worm that targets the
Microsoft Windows operating system. The virus was used to launch the WannaCry ransomware attack.
How Ransomware can harm your Computer and to your Life?
In most cases, the malicious program infects computers through links or attachments in messages known as phishing emails.
"The age-old advice is to never click on a link in an email," said by a senior malware intelligence researcher at Malwarebytes, a San Jose-based company that has released anti-ransomware software.
"The idea is to try to trick the victim into running a malicious piece of code."
The malicious program is usually hidden within the links or attachments which come in emails. The clickbait might just compel the user to click on the link. When the user clicks on such links or downloads such documents, it is then when the malware is installed in the background without the knowledge of the user.
As we already mentioned that this kind of malware mostly attacks on the Windows Operation System like Windows XP, Windows 7, Windows 8.1, Windows 10 etc and also on all Windows Operation Systems like on DOS also. So, this malware can hack all ATMs who runs on Windows OS and also can hack all servers who still depends only on the Windows OS.
What would be it's Effect in India?
India is world's major country and also stands in the world's top 20 country and it's Economy also growing day by day, Many outside countries are coming in India for growing their business, so it's a leading mentor for across the world, that why they also can harm India too, as we also knows that mostly the ATMs in India is operating on the Windows. So, it can be harmful to India as well.
What do they want from us?
If hackers hack your site or any thing and then they want money to realise our site they always wants money in the BitCoin form. IF they are asking money to you, don't give money to them else they can hack another pc and they will ask money also from them.
do you know the rate of bitcoins?

| This is Rate of Bitcoins to Dollars |
Reaction from the peoples across the world who hacked by Wannacry Ransomware....
 |
| It happened Till Yet |
My entire music collection from the past 11 years got encrypted by ransomware.
Is there anything I can do about it?
They’re asking for $500 for the decryption key.
My photos and videos of my wedding has been hacked and they contains some very private photos and video as well:
They are asking 50 Bitcoins to decryption key and give my data back?
He looked down and said a bitter „no”.
How to Protect Your Computer from Ransomware Attack?
1. Always Install Security Updates
If you are using any version of Windows, except Windows 10, with SMB protocol enabled, make sure your computer should always receive updates automatically from the Microsoft, and it’s up-to-date always.
2. Patch SMB Vulnerability
Since WannaCry has been exploiting a critical SMB remote code execution vulnerability (CVE-2017-0148) for which Microsoft has already released a patch (
MS17-010) in the month of March, you are advised to ensure your system has installed those patches.
Moreover, Microsoft has been very generous to its users in this difficult time that the company has even released the SMB patches (
download from here) for its unsupported versions of Windows as well, including Windows XP, Vista, 8, Server 2003 and 2008.
Note: If you are using Windows 10 Creators Update (1703), you are not vulnerable to SMB vulnerability.
3. Disable SMB
Even if you have installed the patches, you are advised to disable Server Message Block version 1 (SMBv1) protocol, which is enabled by default on Windows, to prevent against WannaCry ransomware attacks.
Here's the list of simple steps you can follow to disable SMBv1:
- Go to Windows' Control Panel and open 'Programs.'
- Open 'Features' under Programs and click 'Turn Windows Features on and off.'
- Now, scroll down to find 'SMB 1.0/CIFS File Sharing Support' and uncheck it.
- Then click OK, close the control Panel and restart the computer.
4. Enable Firewall & Block SMB Ports
Always keep your firewall enabled, and if you need to keep SMBv1 enabled, then just modify your firewall configurations to block access to SMB ports over the Internet. The protocol operates on TCP ports 137, 139, and 445, and over UDP ports 137 and 138.
5. Use an Antivirus Program
An evergreen solution to prevent against most threats is to use a good antivirus software from a reputable vendor and always keep it up-to-date.
Almost all antivirus vendors have already added detection capability to block WannaCry, as well as to prevent the secret installations from malicious applications in the background.
6. Be Suspicious of Emails, Websites, and Apps
Unlike WannaCry, most ransomware spread through phishing emails, malicious adverts on websites, and third-party apps and programs.
So, you should always exercise caution when opening uninvited documents sent over an email and clicking on links inside those documents unless verifying the source to safeguard against such ransomware infection.
Also, never download any app from third-party sources, and read reviews even before installing apps from official stores.
7. Regular Backup your Files: (imp)
To always have a tight grip on all your important documents and files, keep a good backup routine in place that makes their copies to an external storage device which is not always connected to your computer.
That way, if any ransomware infects you, it can not encrypt your backups.
8. Keep Your Knowledge Up-to-Date (imp)
There's not a single day that goes without any report on cyber attacks and vulnerabilities in popular software and services, such as Android, iOS, Windows, Linux and Mac Computers as well.
So, it’s high time for users of any domain to follow day-to-day happening of the cyber world, which would not only help them to keep their knowledge up-to-date, but also prevent against even sophisticated cyber attacks.
Individuals and small businesses should: (in short)
- Run Windows Update to get the latest software updates.
- Update your windows to latest patches.
- Make sure any anti-virus product is up to date and scan your computer for any malicious programs. It's also worth setting up regular auto-scans.
- Back up important data on your computer in case it gets held for ransom.
What to do if WannaCry infects you?
If WannaCry ransomware has infected you, you can’t decrypt your files until you pay a ransom money to the hackers and get a secret key to unlock your file.
Never Pay the Ransom:
It’s up to the affected organizations and individuals to decide whether or not to pay the ransom, depending upon the importance of their files locked by the ransomware.
But before making any final decision, just keep in mind: there's no guarantee that even after paying the ransom, you would regain control of your files.
Moreover, paying ransom also encourages cyber criminals to come up with similar threats and extort money from the larger audience.
So, sure shot advice to all users is — Don't Pay the Ransom.
