Sample Essay on Ransomware: Hacking for Blackmail

essay-on-locky-file Ransomware is the kind of a malware infection that is typically used to perform the data kidnapping. Put in one’s PC by a hacker, ransomware simply blocks the PC owner’s access to his important files in order to scare some bucks out of a poor human being. With the most recent ransomware news popping up here and there, it’s not that easy to keep track of the various strains. But the reality is they’re always broken up into a range of key variants. While each of them is spread in its special way, together they all rely on quite similar tactics to benefit from online users. Let us take a closer look at the strains that are the most common nowadays.

 

For the last twenty years, ransomware has been around in this or that form. However, it really got famous with the appearance of CryptoLocker in 2013. The CryptoLocker hackers had managed to extort up to $3 million from poor victims before the botnet was shut down in 2014. From that moment, the approaches applied by the CryptoLocker hackers have been intensively copied. Nowadays, the word “CryptoLocker” is a synonym for the “ransomware.”

When it comes to Locky, it’s a quite new sort of ransomware. Nonetheless, the malware has a well-known approach. It is being spread through spam, as a rule, in a form of a traditional email letter that is designed as an invoice. Once it gets opened, the message is scrambled, while you’re informed on your inability to read the document.

Typically, this kind of “geographically targeted” ransomware is spread using spam emails. TorrentLocker is sending a message to specific regions of the world and using the AES algorithm in order to encrypt each of the file types. Besides, the ransomware also collects various email addresses from your address book to have an opportunity to distribute malware far beyond your own PC – that’s what TorrentLocker is about!

Meet yet another new type of ransomware called TeslaCrypt. Just like all the other examples offered here, this one is using the AES algorithm for the files’ encryption. Usually, TeslaCrypt is spread through the Angler exploit kit targeting at Adobe vulnerabilities. The very moment vulnerability is exploited, the ransomware is installing itself directly into the Microsoft temp folder.

According to the materials provided by the ArsTechnica, this ransomware was discovered not long ago on a BitTorrent client. Even though the ransomware isn’t that widespread nowadays, it should be taken into consideration since it’s the very first completely functioning ransomware created especially to lock the apps of Mac OS X.

There is no need to get panic-stricken when it comes to ransomware; however, it is highly important to realize how crucial it is to protect your system from this malware via setting up a reliable cybersecurity program.
