Ransomware is malicious software that encrypts files on a device and demands payment, usually in cryptocurrency, for the key to decrypt them. There are two main types: crypto ransomware, which encrypts files silently, and locker ransomware, which locks the screen. Ransomware can enter devices through email attachments, infected websites, or networks. Payment demands vary but often specify cryptocurrencies like bitcoin for anonymity. Users should keep software updated, use antivirus tools to scan and remove ransomware, and download free decryption tools if infected.

~How to prevent Ransomware attacks
~Biggest Ransomware attack
~Impact of Ransomware Attacks
~Facts and figures related to Ransomware
Ransomware is a hot topic that isn't going away anytime soon. As more strains of this nasty malware are born, it's important to have a clear understanding about what this threat could mean for your business!
This presentation is about Ransomware. It tells you about how ransomware creates problem and how it can be removed. It also describes different types of Ransomware.
Hospitals, school districts, state and local governments, law enforcement agencies, small businesses, large businesses—these are just some of the entities impacted recently by ransomware, an insidious type of malware that encrypts, or locks, valuable digital files and demands a ransom to release them. And, of course, home computers are just as susceptible to ransomware, and the loss of access to personal and often irreplaceable items—including family photos, videos, and other data—can be devastating for individuals as well.

What is Wannacry / Wannacrypt ?
How many Infections ?
What happens to the victim?
How to protect yourself ?
Will Paying the Ransom Help Us?
Conclusion
Ransomware cyber crime is there any solution or prevention is better than cure.
Cyber criminals have made lucrative business and even 100$ ransom gets collected via bitcoin.
Cyber extortion is a crime involving an attack or threat of attack against an enterprise, coupled with a demand for money to stop the attack.
Cyber extortions have taken on multiple forms - encrypting data and holding it hostage, stealing data and threatening exposure, and denying access to data.
Malware locks out the user’s system and demands ransom.
Creates “Zombie Computer” operated remotely.
Individuals and business targeted.
This form of extortion works on the assumption that the data is important enough to the user that they are willing to pay for recovery.
There is however no guarantee of actual recovery, even after payment is made.
The first known ransomware was the 1989 "AIDS" trojan (also known as "PC Cyborg") written by Joseph Popp.

Ransomware is a PC or Mac-based malicious piece of software that encrypts a user or company’s files and forces them to pay a fee to the hacker in order to regain access to their own files.
Not only can ransomware encrypt the files on your computer; the software is smart enough to travel across your network and encrypt any files located on shared network drives. This can lead to a catastrophic situation whereby one infected user can bring an entire company to a halt.
Abstract—Malware or malicious software are exist everywhere
internet or locally. This paper present a category of malware which cybercriminals (hacker, cracker) currently using for monetizing around the world via internet. Ransomware is the name of this category of malware and it has a variety of families inside it. There are two famous basic types crypto ransomware and locker ransomware. Crypto ransomware usually encrypt personal files of the victims with different cryptography algorithms according how crypto ransomware is designed. These cryptographic alogorithm might be symmetric (single key) or asymmetric (double key, public key). The second type of ransomware lock the victim device (personal computer, mobile device, etc) and prevent the user from accessing it. The countermeasures how to keep secure and safe our systems or
network against this dangerous type of malware will be discuss
also.
Backup is always been the best way to deal with ransomware. Make sure to back up your data in a separate external storage device or you can store your data in the cloud. Use Capebera.com -cloud service to store your data and the best part of the cloud is that it’s not connected to your computer. And in case, your data get encrypted with ransomware threats, you can reboot or reset your system and get back up your data again using Capebera.
Never before in the history of human kind have people across the world been subjected to extortion on a massive scale as they are today. In recent years, personal use of computers and the internet has exploded and, along with this massive growth, cybercriminals have emerged to feed off this burgeoning market, targeting innocent users with a wide range of malware. The vast majority of these threats are aimed at directly or indirectly making money from the victims. Today, ransomware has emerged as one of the most troublesome malware categories of our time.
There are two basic types of ransomware in circulation. The most common type today is crypto ransomware, which aims to encrypt personal data and files. The other, known as locker ransomware, is designed to lock the computer, preventing victims from using it. In this research, we will take a look at how the ransomware types work, not just from a technological point of view but also from a psychological viewpoint. We will also look at how these threats evolved, what factors are at play to make ransomware the major problem that it is today, and where ransomware is likely to surface next.

What is Ransomware? How You Can Protect Your SystemClickSSL
Ransomware is malicious software that prevents user to access their system or data and only allow them to access their files only when user pay some ransom amount to the hackers. Most of the time the Ransom is collected through digital currencies such as Ukash and Bitcoins which are difficult to trace.

2. What is Ransomware
Ransomware is malicious code that is used by cybercriminals to launch
data kidnapping and lockscreen attacks. The motive for ransomware
attacks is monetary, and unlike other types of attacks, the victim is
usually notified that an exploit has occurred and is given instructions for
how to recover from the attack. Payment is often demanded in virtual
currency to protect the criminal’s identity
3. Types of Ransomware: Crypto and Locker
1. CRYPTO Ransomware
Crypto ransomware is as simple as
weaponizing strong encryption against
victims to deny them access to those
files. Once the ransomware infiltrates the
victim's device, the malware silently
identifies and encrypts valuable
filesCrypto ransomware often includes a
time limit
4.
5. Where ransomware comes from
Ransomware is created by
scammers who are highly
knowledgeable in computer
programming. It can enter your
PC through an email attachment
or through your browser if you
happen to visit a website that is
infected with this type of
malware. It can also access your
PC via your network.
6.
7. Ransom Prices and Payment
Ransom prices vary depending on the
ransomware variant and the price or exchange
rates of digital currencies. Thanks to the
perceived anonymity offered by
cryptocurrencies, ransomware operators
commonly specify ransom payments in
bitcoins. Recent ransomware variants have also
listed alternative payment options such as
iTunes and Amazon gift cards.
8. How to remove ransomware
Make use of your antivirus software's ransomware removal tool, which should
scan for and wipe out any ransomware attempts found on your computer.
Make sure all software on your computer is up to date, including your operating
system, browser and any toolbar plug-ins you use.
Ensure that your antivirus software and firewall protection is up to date.
9. Free ransomware removal tools
You can download free anti-ransomware tools below. These tools will
remove ransomware viruses from your computer and decrypt any files
that have been encrypted in the attack. They’ll also inform you about the
types of ransomware and show you what they look like.
