What is Ransomware? How to protect yourself?

Ransomware

         Ransomware is malware that locks keyboards and computers so that you can not access data until you normally pay ransom with Bitcoin. Digital fraud is not new, it began around 2005, but in the development of ransom password file, the attacker has greatly improved the program, only the attacker owns the secret key, encrypts the file, Rather than locking the computer, recently, cyber attacks throughout the world have spread agencies to countless computers in more than 150 countries.

       And recently, it not only affects desktops and laptops, but also mobile phones. In 2015, the murderer was disguised as an application of wild porn. The so-called Porn Droid application is intended for Android users, allowing an attacker to lock the phone and change the PIN and request victims a ransom of 500 dollars to restore access.

        That year, the FBI warned that all kinds of ransom are rising. Individuals, companies, government agencies, academic institutions, even, even law enforcement officers are victims. Malware can infect malicious e-mails and websites, and if an attacker infects the backdoor, an attacker could infect your computer directly.

What is the benefit of ransomware? 

     In 2012, Symantec accessed the command and control server used in CryptoDefense malware and gave a glimpse of the hacker's delinquency situation based on the two Bitcoin addresses the attacker used to receive the ransom. Approximately 3% of 5,700 computers infected with malware a day seems to have sold ransom. The average cost per victim is 200 dollars, and Symantec estimates that an attacker will pay at least $ 34,000 (. Pdf) on that day. By looking at it, you get $ 394,000 in revenue in a month. It is based on data from the command server and two bit member addresses, allowing an attacker to operate with multiple servers and Bitcoin addresses.

Protection (How to Be Safe)

     Do following to face any kind of unusual conditions:

1. Always keep a backup of your files in clouds. So you can access them after facing a ransomware attack.

2. Already use a good Antivirus program in your PC. I recommend you to use Paid version of antivirus but free versions also work good.

3. Always keep your Applications and data up-to-date. So there'll be less chances of backdoors and security bugs.

4. Never pay Ransom as it encourages hackers to attack others.
