How can ransomware be prevented?
, prevent, and detailed
Most people have heard of ransomware, but many don’t know what it is. Ransomware is a type of malware that encrypts a person’s files and demands a ransom be paid to unlock the files. ransomware can be very harmful because it can prevent a person from accessing their own files. In some cases, ransomware can encrypt a person’s entire hard drive, making it impossible to use their computer.
There are a few things that can be done to prevent ransomware. First, it’s important to have a good antivirus program installed on your computer. Antivirus programs can detect and remove ransomware before it has a chance to encrypt your files. Additionally, you should avoid opening email attachments from people you don’t know, and be careful about what websites you visit. Some websites can install ransomware on your computer simply by you visiting them. Finally, you should regularly back up your files so that if you do get ransomware, you can restore your files from a backup.
What is the most effective way to defend against ransomware?
, effective, and defense
Ransomware is a type of malicious software that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. Ransomware attacks are becoming increasingly common. In fact, a ransomware attack is discovered every 14 seconds, on average.
The best way to defend against ransomware is to have a robust backup and disaster recovery plan. This way, if your systems are infected with ransomware, you can restore your data from a backup and avoid paying the ransom.
There are a few key things to keep in mind when designing your backup and disaster recovery plan:
– Make sure your backups are stored offline. This will prevent ransomware from encrypting your backups.
– Ensure that your backups are stored in multiple locations. This will protect you if one location is compromised.
– Test your backups regularly to make sure they can be restored successfully.
– Have a plan for how you will recover your data in the event of a ransomware attack. This should include detailed instructions for all members of your team.
By following these best practices, you can create a robust backup and disaster recovery plan that will protect your data in the event of a ransomware attack.

Ransomware is a type of malicious software from the cryptovirology that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. Ransomware typically encrypts files on the infected computer, making them inaccessible, and demands a ransom be paid to a provided account to decrypt the files, typically in Bitcoin. Some forms of ransomware impersonate cryptoWall, FBI Moneypak, police department lockers, and game company logos like Bethesda to trick victims into paying the ransom. Ransomware has been used against individuals, and also against large enterprises.
The first known ransomware Trojan was created in 1989 by Joseph L. DeMaster, a first-year graduate student at the University of Calgary in Alberta, Canada. The program, called AIDS or PC Cyborg, was initially spread on bulletin board systems. It displayed a message claiming the victim’s computer had been infected with the AIDS virus, and demanded US$189 (equivalent to $337 in 2018) to a provided account to decrypt the files.
According to DeMaster, the idea for the program came about as a way to deter thieves from stealing computers from the University. He created the program to encrypt the hard drive of any computer it infected, and display a message demanding payment for the decryption key. If the victim did not pay within a certain time, the key would be destroyed and the data would be lost forever. However, the program had a flaw that allowed the files to be easily recovered without paying the ransom.
In May 2005, the first known ransomware attack occurred against the now-defunct website G Trog. The website was infected with the virus “Gpcode.A”, which encrypted certain types of files on the victim’s computer and demanded a payment of $300 (equivalent to $434 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In September 2005, the “Zepto” virus was discovered, which was very similar to the Gpcode.A virus. The virus encrypted certain types of files on the victim’s computer and demanded a payment of $200 (equivalent to $290 in 2018) to a provided account to decrypt the files. However, the virus did not have a timer, and the key was not destroyed if payment was not made.
In November 2013, the “Cryptolocker” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $300 (equivalent to $434 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In September 2014, the “Cryptowall” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $500 (equivalent to $725 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In December 2016, the “WannaCry” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $300 (equivalent to $434 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In May 2017, the “Petya” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $300 (equivalent to $434 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In December 2017, the “NotPetya” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $300 (equivalent to $434 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In September 2018, the “Maze” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $2000 (equivalent to $2850 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In October 2018, the “Ryuk” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $30000 (equivalent to $434000 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In November 2018, the “LockerGoga” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $10000 (equivalent to $143400 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
In December 2018, the “Sodinokibi” virus was discovered, which was a ransomware Trojan that used strong encryption to encrypt certain types of files on the victim’s computer and demanded a payment of $25000 (equivalent to $358400 in 2018) to a provided account to decrypt the files. The virus also displayed a countdown timer, threatening to delete the key if payment was not made within a certain time.
