What is Malware
These days, the term malware refers to a large variety of software which all has one thing in common: it is unwanted software which someone else wants to run on your computer. This software infects your computer, making it behave in a way which you have not approved of.
Malware can sometimes include traditional viruses and worms, which are usually destructive in some way - these can delete files, wreck the operating system and change the behaviour of your computer.
Spyware has often been referred to as a virus, but this is not wholly accurate. Often the software does not duplicate itself like a virus, which is why it is almost never detected when a simple anti-virus program like the commonly used McAfee, Norton and Kaspersky anti virus scans are run.
Some modern trojan viruses and worms can give control of your computer to an attacker. Once hacked in they can then use your computer to send spam emails of themselves to all of the people in your address book or launch attacks on other computers. One of the newst types of Viral infection has been dubbed ransomware and can literally hold your personal data to ransom.
Ransomware CryptoLocker is a ransomware trojan which targeted computers running Windows it it is believed to have first been posted to the Internet in late 2013. CryptoLocker propagated via infected email attachments, often claiming missed parcel deliveries etc. When activated, the ransomware encrypts certain types of files stored on local and mounted network drives (including all types of office documents emails pictures websites and accounting files) using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid cash voucher) is made by a stated deadline, and threatened to delete the private key if the deadline passes. If the deadline is not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in Bitcoin. Although CryptoLocker itself is easily removed with anti-malware tools, the files remained encrypted in a way which researchers considered infeasible to break. Many said that the ransom should not be paid, but did not offer any other way to recover the crypted files; others said that paying the ransom was the only way to recover files that had not been backed up. Most victims claimed that paying the ransom did not lead to the files being decrypted in any case. The virus has changed significantly in the last five years and although some reports from 2019 say that certain files can now be decrypted from the FireEye, virtually all newer variants of the virus cannot. Some of the above information is from a cryptolocker wikipedia article.
