WannaCry ðŸ˜
This WannaCryhlengware contains many things. It comes in the form of a download on an infected computer, a self-contained program that works with other software components embedded within it. Those parts include:
An application that encrypts and encrypts data
Files with encryption keys
Copy of Tor
System code is not blocked and it was much easier for those who want security to analyze it. Once launched, Wannacry is trying to access a URL with a strong code (called **** switch); If it can't, it continues to find and encrypt files in many important formats, from small office billing files to MP3s and MKVs, which the user cannot access. It also displays a redemption notification for the required 300 Bitcoin encryption files.
History
The WannaCryhlengwareware attack was a global epidemic that occurred in May 2017.
This hacking attack is broadcast from a computer running Microsoft. User files are being held hostage, and bitcoin ransom is being demanded for their compensation.
If it were not for the continued use of old computer programs and poor education needed to update software, the damage from these attacks could have been avoided.
Older computers, like older computer programs, are more likely to be targeted for malware attacks.
How does the WannaCry attack work?
The perpetrators of cybercriminals involved in the attack have used the practice to exploit the vulnerability of the Microsoft .ft Windows app, which was accused by the United States National Security Agency.
Known as EternalBlue, the burglary was carried out by a group of hijackers called Shadow Brokers before the Vancouver attack.
Microsoft has released a security feature that protects user systems from this, about two months before the start of the WannaCryhlengwareware attack. Unfortunately, many people and organizations do not regularly update their operating systems and therefore receive attacks.
People who did not use the small .ft windows update before the attack did not make good use of the patch and the danger posed by EternalW left them open to attack.
When it first happened, people thought that the WannaCryhlengwareware attack was initially spread by phishing scams (phishing scams where spam emails with infected links or attachments entice users to download wareware). However, Eternal Blue was an exploit that allowed Wannacry to spread and spread, there were computerized "backdowns" (used to make Wannacry) in DoublePulsar reduction.
What was the outcome of Wanannakri's attack?
The WannaCry ransomware attack has hit nearly 230,000 computers worldwide.
One of the first companies to be affected was a Spanish mobile phone company, Telefenica. Since May 12, thousands of NHS hospitals and surgeries in the UK have been affected.
The attack affected third-party trust in the NHS. The ambulance has been horribly redesigned, leaving people in urgent need of care. The attack is estimated to cost the NHS £ 92 million after the completion of 19,000.
With the rise of ransomware outside Europe, computer systems are crippled in 150 countries. The attack on WannaCryhlengware had a profound impact on the global economy. It is estimated that these cyber crimes have caused the loss of 4 4 billion people worldwide.
Episode WannaCry
Ironically, the patch needed to prevent Wannakri infection actually existed before the attack began: MicrosoftSF Security Bulletin MS 17-010, published March 14, 2017, is reviving Windows implementation of the SMB protocol to prevent infection with Eternal Blue Is. However, unless Microsoft considered the pool to be important, many programs were unused until May 2017 when Vannakri began its rapid spread.
In those neglected systems, there is no small solution other than restoring files from a backup - so it is always a lesson that you should always back up your files. While some people pay a fine for monitoring Bitcoin wallets in fraudulent messages, there is not much evidence that they regained access to their files.
