It will leave ransom note on your PC and change the desktop wallpaper with ransom image to tell about the infection. Spongebob ransomware will ask that you purchase decoding key to open your documents. It will request cash through bitcoin and give you some an opportunity to pay the cash. It additionally threat clients to erase their records if they neglect to pay cash.

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).

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,

Ransomware is a malicious computer program that encrypts your computers contents and requires a key to unlock the encryption. You are instructed to wire bitcoins (anonymous internet

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

Malware. The use of malware in cyber-attacks against businesses are increasing. Malware is software that is intended to compromise computers and computer systems. Malware can be introduced into systems through a variety of methods, which include phishing emails and visiting compromised websites.

This research project discusses a common threat that is consistently present in the world that we live in today on the front of cybersecurity as well as cyberspace. Among all of the various cyber-attacks that exist in our world today, Ransomware has taken a front seat when discussing the different types of threats that create the potential to harm us users on a day to day basis. This form of threat is something that has been plaguing users for years and has caused financial manipulation for hospitals, businesses, and private citizens as well. This research project will discuss the threats that have been present in the past 5-10 years and will provide an in depth study of what occurred and what could have been done in order to prevent this type of attack from happening. The topic of risk assessment and vulnerability will be analyzed as well.

Viruses get into the computer system by many different ways, it can be through downloading infected files online, opening unknown links or downloading attachments files from emails.

The nature of the cyber threat has changed dramatically over the past 25 years. In the early days of the personal computer, hackers were mostly motivated by the lulz, or laughs. They hacked computer systems just to prove that they could do it or to make a point. One of the very first computer viruses to infect IBM PCs was the Brain virus, created in 1986 by brothers Amjad Farooq Alvi and Basit Farooq, aged 24 and 17, of Lahore, Pakistan. Their virus was intended to be innocuous in nature, to stop others from pirating the software the brothers had spent years developing. Brain worked by infecting the boot sector of a floppy disk as a means of preventing its copying and allowed the brothers to track illegal copies of their own software. The brothers, upset that others were pirating their software without paying for it, included an ominous warning which appeared on infected users screens:

LockBox ransomware is a famous bit of malware that noiselessly sneak into your machine. It for the most part gets brought through bundled free third party programs, suspicious sites, spam emails, shareware and different tricks. Once installed on your system, it will also block your anti-virus and firewall security to bear on its dangerous activities. LockBox ransomware can also alter your

I like your take on the lessons learned from the Ransomware attack especially the emphasis on being cautious about phishing. The impact of phishing falls on everyone, however, the worst part is that though phishing is now more than a decade old, many people are still not familiar with how it works and still fall victim to its scam. The main reason why phishing continues to be a successful method of attack is because anti-phishing technologies are often created to counteract phishing by applying technical solutions rather than addressing the human source of the problem (Steinberg, 2014). Cyber criminals use the victims’ computer systems to set up viruses and worms and disseminating phishing emails further to their contacts. I think

April of 2017 saw the introduction of the Onion ransomware virus, one that is of the Dharma ransomware variety. Experts state this is a high risk virus and one that organizations need to protect against. When a computer becomes infected, files will be encrypted with the .onion extension. The computer system owner then receives a short text message explaining what steps have to be taken to restore the infected files and fix the system. If help is needed in doing so, the owner is directed to

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)

Viruses are generally often to steal information from computers that are infected. Most aren't successful. Either way, Viruses set out to harm your computer and it can also be a way for a computer virus to steal credit card numbers, passwords or account numbers and other sensitive data.
