Virus Spyware and Ransomware
Worms
A worm is a program that makes and facilitates the distribution of copies of itself; for example, from one disk drive to another, or by copying itself using email or another transport mechanism. The worm may do damage and compromise the security of the computer. It may arrive via exploitation of a system vulnerability or by clicking on an infected e-mail.

Spyware
What is it?
Software that enables a user to obtain covert information about another's computer activities by transmitting data covertly from their hard drive.
Examples of Spyware
With the development of cybersecurity technologies over the years, many spyware programs have disappeared, while some other, more sophisticated forms of spyware have emerged. Some of the best-known examples of spyware include the following:
- CoolWebSearch – This program would take advantage of the security vulnerabilities in Internet Explorer to hijack the browser, change the settings, and send browsing data to its author.
- Gator – Usually bundled with file-sharing software like Kazaa, this program would monitor the victim’s web surfing habits and use the information to serve them with better-targeted ads.
- Internet Optimizer – Particularly popular in the dial-up days, this program promised to help increase internet speeds. Instead, it would replace all error and login pages with advertisements.
- TIBS Dialer – This was a modem hijacker that would disconnect the victim’s computer from a local phone line and connect them to a toll number designed for accessing pornographic sites.
- Zlob – Also known as Zlob Trojan, this program uses vulnerabilities in the ActiveX codec to download itself to a computer and record search and browsing histories, as well as keystrokes.

Ransomware
What is it?
Ransomware is a type of malicious software designed to block access to a computer system or computer files until a sum of money is paid. Most ransomware variants encrypt the files on the affected computer, making them inaccessible, and demand a ransom payment to restore access.
Examples of Ransomware
CryptoLocker - CyptoLocker botnet is one of the oldest forms of cyber attacks which has been around for the past two decades. The CyptoLocker ransomware came into existence in 2013 when hackers used the original CryptoLocker botnet approach in ransomware.CyptoLocker ransomware is the most destructive form of ransomware since it uses strong encryption algorithms. It is often impossible to decrypt (restore) the Crypto ransomware-infected computer and files without paying the ransom.
WannaCry - WannaCry is the most widely known ransomware variant across the globe. The WannaCry ransomware has infected nearly 125,000 organizations in over 150 countries. Some of the alternative names given to the WannaCry ransomware are WCry or WanaCrypt0r.
Bad Rabbit - Bad Rabbit is another strain of ransomware which has infected organizations across Russia and Eastern Europe. It usually spreads through a fake Adobe Flash update on compromised websites.
Cerber - Cerber is another ransomware variant which targets cloud-based Office 365 users. Millions of Office 365 users have fallen prey to an elaborate phishing campaign carried out by the Cerber ransomware.
Crysis - Crysis is a special type of ransomware which encrypts files on fixed drives, removable drives, and network drives. It spreads through malicious email attachments with double-file extension. It uses strong encryption algorithms making it difficult to decrypt within a fair amount of time.
CryptoWall - CryptoWall is an advanced form of CryptoLocker ransomware. It came into existence since early 2014 after the downfall of the original CryptoLocker variant. Today, there are multiple variants of CryptoWall in existence. It includes CryptoDefense, CryptoBit, CryptoWall 2.0, and CryptoWall 3.0.
GoldenEye - GoldenEye is similar to the infamous Petya ransomware. It spreads through a massive social engineering campaign that targets human resources departments. When a user downloads a GoldenEye-infected file, it silently launches a macro which encrypts files on the victim's computer.
Jigsaw - Jigsaw is one of the most destructive types of ransomware which encrypts and progressively deletes the encrypted files until a ransom is paid. It starts deleting the files one after the other on an hourly basis until the 72-hour mark- when all the remaining files are deleted.
Locky - Locky is another ransomware variant which is designed to lock the victim's computer and prevent them from using it until a ransom is paid. It usually spread through seemingly benign email message disguised as an invoice.When a user opens the email attachment, the invoice gets deleted automatically, and the victim is directed to enable macros to read the document. When the victim enables macros, Locky begins encrypting multiple file types using AES encryption.Apart from the list of ransomware mentioned above, Petya, NotPetya, TeslaCrypt, TorrentLocker, ZCryptor, etc., are some of the other ransomware variants that are well-known for their malicious activities.
