Wannacry
The WannaCry ransomware was found in May,2017. This ransomware looks for and tries to encrypt about 176 file types as well as appends. It puts the words WCRY at the end of a file name. Following that its asks the user victims to pay a ransom in the form of bitcoins. The note says that after three days of nonpayment the amount will double. After seven days, the encrypted files have a possibility of being deleted. The way that the ransom payment is set up is the attackers request to be paid by the form of bitcoins. The unique Bitcoin walled address in the infected computer in this case does not execute correctly. Therefore, the WannaCry goes into a three-hardcoded bitcoin address to receive the payments. This ransomware is said to be the works of a hacking group known as shadow brokers. They claim to have discovered flaws from the United States Security Agency (NSA).

In this case, the focus is on the unpatched Windows computer which are susceptible to this ransomware. Some of the older Windows operating system like Windows Vista, XP or even internet explorer 8 you will not receive some critical patches for your system. The attack does not seem to be a targeted one. When the systems are found unpatched the WannaCry can spread itself inside the corporation networks without the need of user interaction. The reason here being that the likely cause of this type of spread is a worm. This worm spreads itself is infected and attaches to a network. IT has spread from Russia, Ukraine, Taiwan and many other countries. Some common targets include the healthcare sector. The reason being they have poor cybersecurity. Staff is more vulnerable to attacks like phishing, since they tend to click on links without thinking about it twice. One of the main reasons this affected them a lot was by not having any backup
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 company must ensure that proper steps were taken to remove all affects systems from the network. Ensure that systems were reimaged and passwords reset. Latest virus definitions need to be updated along with all security patches in order to fix any vulnerability that was exploited by the hacker. Unused services should also be disabled in order to harden the system against any future attacks. All of the affected computers should also have been reimaged. The company might need to reiterate

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

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.

The email appears to victims in their inbox as an attempt of an agency to collect a medical account debt that is severely past due. The email appears legit and catches the attention of anyone who suspects they might legitimately have an overdue medical bill from the past. The link in the email contains the virus, and once the victim clicks on it, their account information, including name, address, passwords, DOB, age, contacts, file folders, and other sensitive information, is immediately able to be accessed and stolen from the victims. At the same time, the link redirects the victims to the fake webpage created by the criminals to resolve the past due account. The site is set up much like any other business account with an e-pay option, so once the victim enters their bank account and credit card information to reconcile the past due account, their accounts are sucked dry and the money is routed to the pay pal account where the criminals can immediately access
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.
Network viruses are another favorite method of cyber criminals. As we all know, viruses can bring a network to
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)
Cybercrime has become a fast growing concern for the 21st century as businesses, institutions and individuals grow into an interconnected web of computer networks. Online business transactions, along with the sharing of personal information, are vulnerable to a host of disasters that can reap economic and social havoc. Some sources say that today, cybercrime costs more than $1.0 trillion to society--Global Industry Analysts, Inc. forecasted the world cyber security market to reach $80 billion by 2017 (Gale, 2011).
