What is the wanna cry virus?
Summary of the Article
What did the WannaCry virus do?
WannaCry is a ransomware worm that spread rapidly across a number of computer networks in May of 2017. It encrypts files on the PC’s hard drive, making them impossible for users to access, and demands a ransom payment in bitcoin to decrypt them.
What is WannaCry and how does it work?
WannaCry is ransomware that contains a worm component. It exploits vulnerabilities in the Windows SMBv1 server to remotely compromise systems, encrypt files, and spread to other hosts. Systems that have installed the MS17-010 patch are not vulnerable to the exploits used.
Is WannaCry still active?
A team of French researchers found a way to decrypt some affected computers without paying a ransom. However, WannaCry is still active. It is important to regularly update your Windows operating system to ensure you have the latest security patches.
Who created the WannaCry virus?
WannaCry propagated using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack.
How did people get infected with WannaCry?
WannaCry spreads by using corporate networks to jump to other Windows systems. Unlike phishing attacks, computer users don’t have to click on a link or open an infected file.
How much money did WannaCry make?
The attackers made $386,905 through the attack, but a significant amount will be lost during the process of converting the cryptocurrency to real money.
Who stopped WannaCry?
Marcus Hutchins, also known as MalwareTech, is a British computer security researcher who halted WannaCry’s spread by registering the URL found in its code, activating the program’s kill switch.
Who was targeted by WannaCry?
WannaCry targets computers using Microsoft Windows as an operating system. It encrypts data and demands payment of a ransom in the cryptocurrency Bitcoin for its return.
What country was most affected by WannaCry?
China was the most affected country, with 6.2 million requests, despite initial reports claiming that between 50% and 75% of WannaCry victims were from Russia.
Who destroyed WannaCry?
MalwareTech, also known as Marcus Hutchins, stopped WannaCry’s spread by registering the URL found in its code and activating the program’s kill switch. Other researchers also developed methods to decrypt files held hostage by WannaCry.
Who was the hacker who stopped WannaCry?
Marcus Hutchins, at 22 years old, single-handedly put a stop to the worst cyberattack the world had ever seen. However, he was later arrested by the FBI.
Did the creator of WannaCry get caught?
The article does not mention whether the creator of WannaCry was caught or not.

How did people get infected with WannaCry
The way WannaCry spreads is by using corporate networks to jump to other Windows systems. Unlike phishing attacks, computer users don't have to click on a link or open an infected file.
How much money did WannaCry make
$386,905 may not seem like much of a payday considering the number of devices infected and the damage caused by the attack, and it's not. Further, the attackers will need to convert that total to real money, and a considerable amount will be lost in that process.
Who killed WannaCry
Marcus Hutchins
Marcus Hutchins (born 1994), also known online as MalwareTech, is a British computer security researcher known for stopping the WannaCry ransomware attack.
Who was targeted by WannaCry
Microsoft Windows
WannaCry targets computers using Microsoft Windows as an operating system. It encrypts data and demands payment of a ransom in the cryptocurrency Bitcoin for its return.
What country was most affected by WannaCry
Although initial reports claimed that between 50% and 75% of WannaCry victims were from Russia, the Kryptos Logic data suggests that China was by far the most affected country, with 6.2 million requests.
Who destroyed WannaCry
MalwareTech aka Marcus Hutchins halted WannaCry's spread by registering the URL found in its code, activating the program's kill switch. Through defensive cryptanalysis of WannaCry, other researchers developed methods to decrypt files that were held hostage so long as the owner did not reboot the infected computer.
Who was the hacker who stopped WannaCry
At 22, he single-handedly put a stop to the worst cyberattack the world had ever seen. Then he was arrested by the FBI.
Did the creator of WannaCry get caught
Arrest. On 3 August 2017, Hutchins was arrested by the FBI as he was preparing to return to England from DEF CON on six hacking-related federal charges in the U.S. District Court for the Eastern District of Wisconsin for creating and spreading Kronos in 2014 and 2015.
Did the creators of WannaCry get caught
That heroic status was tarnished when, as he travelled home following the Black Hat and Def Con security conferences, Hutchins was arrested by the FBI at the Las Vegas McCarran International Airport.
Did the WannaCry hackers get caught
Marcus Hutchins, the 23-year-old British security researcher who was credited with stopping the WannaCry outbreak in its tracks by discovering a hidden “kill switch” for the malware, has been arrested by the FBI over his alleged involvement in separate malicious software targeting bank accounts.
Who solved the WannaCry virus
Marcus Hutchins (born 1994), also known online as MalwareTech, is a British computer security researcher known for stopping the WannaCry ransomware attack. He is employed by cybersecurity firm Kryptos Logic. Hutchins is from Ilfracombe in Devon.
How much money was lost in WannaCry
Within a day, WannaCry had spread around the world, infecting more than 230,000 computer systems in 150 countries and costing approximately $4 billion in financial losses. It was the most virulent self-spreading malware since 2003 when the Slammer worm infected most of its victims within one hour.
How much money was paid to WannaCry
By today's standards, the ransom demand was very small. Just $300 per infected device, which doubled to $600 if the payment was not paid within 3 days.
