How to remove Locky ransomware from Mac
Locky is the nickname of a crypto-ransomware that infects computers by encrypting files and preventing user access. Cybercriminals use it to scare victims into handing over money. They hold encrypted data to ransom and demand payment for a decryption key that can restore inaccessible files. But nobody guarantees that after making a payment, you will get your data back unscathed.
The good news is that you can remove Locky ransomware from your computer in no time without the need to pay the ransom. In this article, we’ll show you how to get rid of this malware in a few simple steps and protect your Mac from future threats.
What is Locky ransomware?
In February 2016, Locky authors used the Necurs botnet to run a massive spam campaign, sending emails with the malicious code called to encrypt users’ data. The ransomware quickly spread throughout the world but affected North America and Europe the most. Since that time, it has become one of the most ever-multiplying members of the ransomware family.
The initial extension of encrypted files was LOCKY. As the malware evolving, new editions occurred, introducing new file extensions.
Locky ransomware attacks individual users and large businesses. One of the first most significant attacks hit primarily the healthcare sector as well as the transportation, telecom, and manufacturing industries. The virus is best known for a high-profile infection at a hospital in Los Angeles, which paid a $17,000 ransom to recover its data.
How did Locky get on my computer?
Ransomware authors spread the infection via fraudulent emails similar to those used by Dridex malware focused on stealing banking information. The email is designed to make you believe that it comes from a reputable company. It always includes an attachment which you’ll be asked to download. Usually, it’s Word, Excel, or ZIP file disguised as an invoice. Here is a typical scam email with Locky virus:

How does Locky ransomware work?
Locky is a big player in the malware industry. It’s powerful enough to encrypt over 160 different file types, including videos, images, and Office files. Although Locky tends to infect Windows, it also attacks macOS. Here is how it works:
- You download and open an attached document.
- Content in the document looks like gibberish.
- A warning message advises you to enable macros so that the content can be displayed correctly. But this social engineering technique is used as a bait to trick you.
- By enabling macros, you activate a malicious script that installs Locky malware on your computer.
- The virus begins to lock specific files, rename them to a weird combination of letters and numbers and change extensions.
Once the files are encrypted, Locky starts demanding ransom from you. It asks you to install the Tor browser and make a payment in Bitcoin (BTC) to get the decryption key. Generally, ransom varies from 0.5 to 1.0 BTC, which equals about $3600–$7200 as of December 2019.
How to remove Locky ransomware
First of all, you should ignore it. Never follow the steps described in the ransom note. There is no guarantee that the scammers will keep their promises and turn your files back to life. By fulfilling their demands, you’ll encourage cybercriminals to expand their grim business and use your money to attack even more users.
