MacRansom virus might be the first Ransomware-as-a-Service that targets Mac OS

MacRansom is a malicious Ransomware-as-a-Service[1] virus that targets Mac operating systems and encrypts files stored in them. The developer of the ransomware suggests joining his affiliate system for free and provides ransomware samples for free. It takes less than a minute for this virus to encrypt files on victim’s Mac. After encrypting the files, the virus creates a ransom note (._README_ file) that it displays on the screen, and demands 0.25 Bitcoin (approximately $700). The victims are asked to contact for information on how to decrypt files. Instead of doing so, we suggest you start thinking about MacRansom removal. MacRansom ransomware

Before launching the malicious payload, the ransomware performs several checks – it determines whether it is being run in a Mac environment or not, also if it is being debugged, and if the machine has two CPUs. Following that, the virus creates a launch point: ~/LaunchAgent/ and then copies the ransomware executable to ~/Library/.FS_Store. The virus purposely uses original (or similar) names of legitimate files to avoid detection. The virus also manipulates the time date stamp to confuse investigators. Finally, the virus uses launchctl to open the file it created. The virus checks trigger time and, if the condition is met, it starts the encryption process. After encrypting all of the victim’s files, the ransomware encodes its own files, changes the time date stamp and then removes them from the system.

The ransomware uses symmetric encryption, which, in typical cases, allows decrypting files more easily, however, we do not recommend paying the ransom if your PC has been infected. It turns out that the ransomware doesn’t communicate with C&C server[2], and that means criminals won’t have the copy of it. However, since they key is only 8 bytes long, it might be possible to brute-force it. So if you have been assaulted by this Mac ransomware, we suggest you remove MacRansom from the OS using Malwarebytes software and check available data decryption methods explained at the end of this post.

Distribution methods

Ransomware-as-a-Service is distributed by affiliates who decide to partner with the ransomware developer. Currently, it is being distributed via email spam, although we believe that attackers might be trying to inject the virus into unsecured websites or distribute it alongside untrustworthy or illegal software for Macs. The developer of MacRansom, however, suggests moving the malicious virus to a USB, using it to transfer the malicious file on a target system, and manually launching it. It goes without saying that it is a much slower and more dangerous way to distribute this malicious virus. The ransomware developers promise to give their affiliates 70% from all collected ransoms, keeping 30% to themselves.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
