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 malicious software presented itself to the user as an expired software license and told users to send money. This malware would demand US$189 for it to unlock the system (Michael). There was another ransomware known as Krotten that appeared in 2006 which disabled all files and displayed the text in German.

Winlock originated in Russia in 2010 and did not use encryption. This one would limit access to the computer and display pornographic materials. This one specifically attacked Russia in a very big way. The users of the computers would need to buy some unlocking codes in order to gain access to their computer. Ten individuals were arrested in 2010 concerning their involvement in this ransomware (McMillan). It earned the operators of Winlock US$16 million.

A worm that was similar to Windows Production Activation appeared in 2011 and told Windows users that the windows installation had to be re-activated because the user had been a victim of fraud. It gave a user an option of online installation but the user could not access it so they were required to call an international number and input a 6-digit code. They said...

Ransomware: the Latest Craze

...1 Ransomware: The latest craze Well, not really. Ransomware has been around for over 10 years but has been gaining in popularity as the hackers’ latest way of extorting money from you. So, what is it? As the name implies, it’s malware (malicious software) which has kidnapped your computer and is holding it for ransom. It works like this. You click on an unsuspecting link from a web page, social networking site, email message or (lately) Skype instant message. This launches a program which then starts to encrypt/lock some or all of the files on your hard drive. In the meantime, you are shown a fake web page from the FBI, CIA or some other agency to make you believe you’re in legal trouble and could even face prosecution. They’ll use scare tactics such as telling you that your computer contains illegally downloaded files ranging anywhere from music and movies to child pornography. They will then ask you to pay money for them to unlock and restore your files. As you’ve already probably guessed, they won’t keep their promise. They’ve got your money and now can, and possibly will, sell your credit card info to other hackers and make even more money off of you. They have no reason to “help you out” so, don’t think for a minute that they will help even if you pay them. How can you protect yourself from malware? Keep all of your computer software up to date. Make sure that you have up-to-date firewall and antivirus software installed on your computer. Most......

...Cryptolocker Ransomware: A Ransom no more! Christopher S Ebingersmith University of Maryland University College June 24, 2015 Introduction Cryptolocker Ransomware is part of a larger number of malware campaigns infecting large numbers of computer systems. This new variant of ransomware is more egregious in nature as it not only holds the system hostage as other types of ransomware, but through the course of infection a great number files, when found, are encrypted by this malware. The primary vector of infection is through the use of phishing email attempts to entice unwitting users to click on malicious attachments. Once the system is infected Cryptolocker hides, slowly beginning to affect the availability of files on the affected system communicating back to the “attackers’ command and control (C2) server to deposit the asymmetric key out of the victim’s reach.” (Alert, 2013) Cryptolocker, which only seems to affect Windows based targets, first popped up on security radars in September of 2013, “and these early versions were distributed via social engineering and spam emails that try to entice business professionals into opening an attached Zip file.” (Kostadinov, 2014) The zip files were thinly disguised as a 20kb file with some file names between 13 and 17 characters that mimicked “the look of legitimate businesses and through phony FedEx and UPS tracking notices.”(Alert, 2013) Spamming was the primary method utilized to infect potential hosts; this really......

Attacks

...Ransomware Discuss the threat When infected restricts you to access to a computer system. This will become more refined in its targets and methods. Experts predict that the variants of ransomware that hurt the security software that are installed within a computer may particularly target the endpoints which sign up with cloud-based storage solutions like Google Drive, Dropbox, OneDrive and many more. On detecting the endpoint, ransomware will exploit the stored personal credentials of the logged-in user and will even infect the cloud storage that is backed up. McAfee has warned that ransomware attackers will try out as many ways possible to shell out ransom payments from their victims. Degree of damage The most advanced and most damaging ransomware in the wild at the moment, specifically targeting U.S. businesses and individuals. It's a $70 million per year criminal enterprise. Its magnitude is now confirmed by law enforcement. Some quick math shows $18,145 in costs per victim, caused by network mitigation, network countermeasures, loss of productivity, legal fees, IT services, and/or the purchase of credit monitoring services for employees or customers. As you can see, the total costs of a ransomware infection goes well above just the ransom fee itself, which is usually around $500 but can go up to $10,000. What it attacked Ransomware is a type of malware that infects a computer and restricts a user’s access to the infected computer. This type of......

150 Word Summary + Valuable Feedback

...150 word summary with insightful feedback Article # 4: ( Source from the Economist) Your money or your data; Ransomware With hackers running rampant today, more demands are given by them, now with old-fashioned ransoms. Computer users are now faced with a virus called “ransomware”, which gives users an option of either giving up their data or retrieving it with a fee. Ransomware isn’t likely to go away anytime soon, as new options of exchanging money are now on the internet, from companies such as bitcoin and Paypal, criminals might find them a haven to go to, as there can be anonymity and use of digital currency. Additionally, its programmers are always ahead since they are constantly modifying their code, which keeps them in an advantageous position, and unfortunately, not all their victims get a fair share, many have gotten a broken promise to ransomware’s demands. While this problem will persist, web-users must protect themselves with the best possible solutions to the attack of ransomware’s programmers. Words: 146 Feedback: Never start a sentence with "With".

The virus demands a ransom paid to the creator of the malware for it be removed (Microsoft.com http://www.microsoft.com/security/resources/ransomware-whatis.aspx). When a cracker criminally accesses your computer and infects it with ransomware it locks and owners are no longer able to access their computer or any files that were on the computer. The virus installed could be anything from pornography or fake threats from law enforcement such as the FBI or IRS. If your computer is sieged, a warning will appear on the monitor in the form of a ransom letter coaxing you to pay a hefty ransom. Users are told they must pay a ransom of usually more than $400 to have their computer unlocked. Unfortunately anywhere from 2.9% - 20% of users actually pay this ransom. Once the ransom is paid the computer remains locked and users will need to have the computer professionally wiped clean. In this case the user is out of the......

Bogachev, a 30 year old man from Russia, the supposed ring leader of the whole operation. It is thought that the Trojan infected between 500,000 and one million computers, and syphoning over 100 million dollars into the attackers accounts. Gameover ZeuS was a Trojan that created a botnet and also carried another payload with it, Cryptolocker.
