Ransomware
Ransomware is a type of malware that limits access to a computer system that it affects. Just as its name goes, it then asks for ransom payment to pay to its creator in order for the limitation to be taken away. Some of these malwares encrypt files on the hard drive while others just lock up the system and display messages persuading the user to pay the ransom (Michael). There are two types of ransomware, one that locks the screen and displays a message that prevents you from accessing the computer, and the other that encrypts files on a systems hard drive and prevents one from opening them (Blue).
The first known ransomware was written by Joseph Popp in 1989 and was known as PC Cyborg or “AIDS.” This

This file encryption only works with certain documents that have particular extensions including Microsoft office and open documents.
The computer then displays a message that the files have been encrypted and the user needs to pay a certain amount of money for the files to be decrypted. The operators of CryptoLocker started an online service in November 2013 allowing victims to get buy the key online after the expiry of the deadline (Mark). The victims were required to upload a sample of the infected file and wait for the key to be generated after they paid the ransom. If the deadline had elapsed, then the victim would have to pay more money (Blue).
Files that have been encrypted by CryptoLocker are very hard to break. Experts advised the victims not to pay any money even if they did not come up with any solution for them to recover their files. It was however unfortunate that paying the ransom did not always guarantee that the files were decrypted. The people who were responsible for this malware did not always assure the victims that they were going to decrypt the files (McMillan).
CryptoLocker was isolated in June 2014 through an operation known as Operation Tovar. This operation enabled the security firm to obtain the database of private keys that were used by the CryptoLocker and used an online platform for victims that were affected to obtain the private keys. In August 2014,

Cryptanalysis is the study of analyzing information systems in an attempt to learn the secluded aspects of the systems. It is used to break cryptographic security systems and gain access to the contents of encrypted messages. In The Code Book, it analyzes how people can invade your internet privacy even if you code your information. Viruses on the internet can decipher subsequent messages and programs such as the Trojan Horse can appear as a genuine encryption product, but which actually betrays
In 2013 I got a call from a friend asking if I could stop by and examine his computer. When I arrived there was a message covering his monitor saying, “Department of Justice: Your computer has been suspended on the grounds of the violation of the law in the United States.” After doing some research, I found his computer was infected by the money-pak virus. The scam asked the user to pay 300 dollars to unlock their computer; and, free them of any crime the message stated the user had commit. I believe the culprit was an e-mail attachment that one of his family members downloaded and then opened. I found a fix online by searching for “Department of Justice Money-Pak”, and applied it by running safe-mode with networking on his windows system,
Two weeks ago, a brutal piece of ransomware named Petya started circulating in large number. It became quite notable as it targeted its victim exactly where it hurts: right in the startup drives. It encrypted the master boot file and made it inoperable. As a result, victims couldn’t start their computer and access their data without the decryption password.

Received a call from Billy, had him take his computer off the network and boot it back up. Walked Billy through confirming he did have the crypto virus. Had Billy shut his computer back off, and informed him someone would be on their way to pick up his laptop. Explained to Billy we will need to wipe and reload his computer. With Chris from or offices assistance we located the files that were encrypted. Using a script created by mark we confirmed it was only Billy’s user folder that was encrypted. We did find traces of help_decrypt in the QuickBooks folder, but the QuickBooks data was intact. Using Shadow copy I resorted Billy’s user folder back to 7:00 AM Tuesday, but his files were still encrypted. Restored back to Monday at 12:00 AM and confirmed

The threat is incredibly serious—and growing. Our nation’s critical infrastructure, including both private and public sector networks, are targeted by adversaries. American companies are targeted for trade secrets and other sensitive data, and universities for their cutting-edge research and development. Citizens from anywhere across the globe are targeted by fraudsters and identity thieves, and children are targeted by online predators. Just as the FBI transformed itself to better address the terrorist threat after the 9/11 attacks, this means enhancing the Cyber Division’s investigative capacity to have strong sharp focus on intrusions into government and private computer like network to.hospitals, school districts, state and local governments, law enforcement agencies like the Federal Bureau of Investigation, Central Intelligence Agency, Drug Enforcement Administration, National Security Agency, Naval Criminal investigative Service and Department Of Defense, small businesses, large businesses these are just many who have been impacted by ransomware, a threat type of malware that encrypts, or locks, valuable digital files and
I have written the article about the KKK Ransomware contamination. This irritation is one of the most current increments to the ransomware family. Found not long ago, KKK is identified with the infamous HiddenTear extend and has turned out to be similarly as unsafe as whatever other ransomware piece. It sneaks into your machine and inflicts destruction. It finds and encodes your records along these lines denying you access to them. What is intriguing about KKK, however, is that it just locks the records that are on your Desktop. Be that as it may, this is all that could possibly be needed to cause you a headache. All things considered, the documents you utilize the most are normally in that spot on your Desktop. What's more, the
The suspected killer is somehow able to obtain large amounts of liquid nitrogen to use for his cryogenic freezing. Cleverly, the two situations were connected. The killer was looking for a way to pay for his research on freezing people to be thawed and live again after science was enhanced, so he turned to ransomware. Smart with computers and friends with the computer expert who turned up dead (and frozen) the killer ends up trying to fund his little project by extorting people to pay to have their data returned to normal using ransomware. This isn’t your typical crime, but it definitely had an interesting twist.
The Faizal Ransomware is classified as an encrypted trojan which is distributed by the PC gaming community specialized for the car racing. The Faizal is reported as an installer package which is named as a street racing club- setup.exe. The Faizal is based on the hidden tear project and is able to encrypt files on the removable storage, local disk and shared network which is connected to the machine.
Malwares are mischievous programs crafted to agitate or forbid normal operations to gather selected information which may lead to loss of privacy through
CryptoLocker was first seen in September 2013 and infected computers with the help of a dirty email attachment. This virus was eradicated in June 2014 with the help of the United States Department of Justice. Nevertheless, new ransomware viruses have popped up with similar names that people need to be aware of.
Just like a biological virus, a computer virus is able to infect and ruin lives. This malicious software constitutes more than just simple viruses but also includes other types of software including worms, Trojan horses, and ransomware. Malware has been around since the late 1980’s. Originally, people became hackers to gain notoriety online, but today, it has become more of a business. Cyber attacks originate from all around the world, and it is not just individual people that benefit from it. In two decades, numerous cyber crime syndicates have been created, and states all over the world sponsor hacker groups. Over the past twenty-five years, malware has become less about checking the integrity of computer security and gaining notoriety in the underground cyber society, and it has become more of a chaos creating, money making business that many people and institutions take part in.
Variants of ransomware now allow victims to “pay” by spreading the malware to their friends and family. Another variant, Spora, allows tiered payments that unlock “some” or “all” of a victim’s encrypted files or grant “immunity” from the virus that infected them. Expect that to continue in 2017 with an emphasis on alternative payment modes (always the trickiest part of the ransomware scheme). (Roberts, 2017)
