What is Maoloa ransomware? And how does it carry out its attack?

Maoloa ransomware is a file-encrypting malware discovered on the first week of February 2019. Like other typical ransomware threats, this one is also designed to lock important data in a computer and demand ransom from victims. It uses the “.maoloa” extension in marking its encrypted files and urges users to contact email addresses such as [email protected], [email protected], [email protected].
Once it infiltrates a computer, Maoloa ransomware will drop its malicious payload which initiates the attack by connecting the computer to a remote server. After that, it downloads its malicious components and drops them on several system folders which are used to manipulate system processes and employ several modules like the information gathering module and stealth protection module.
It first employs the information gathering module which gathers information from the computer. The information gathered may consist of machine identification data and personal information of the user. The collected information is then used to bypass any security software in the system by looking for engines of applications that can block the attack of Maoloa ransomware. Furthermore, it also alters the Windows Registry by modifying existing entries and creating new ones to allow it to run automatically each time the infected computer is turned on. After these system changes, it starts the encryption using a sophisticated encryption algorithm and once the encryption is finished, it appends the .maoloa suffix to all the affected files. It then drops a text file named HOW BACK YOUR FILES.txt which contains the following content:
“** All your files have been encrypted **
| * Do not rename encrypted files. |
| * Do not try to decrypt your data using third party software, this can |
| result in complete data loss. |
Send us email with your personal id.
This email will be as confirmation you are ready to pay for decryption key.

How is the malicious payload of Maoloa ransomware disseminated over the web?
The malicious payload of Maoloa ransomware may be disseminated using several techniques. For one, it could spread via malicious spam email campaigns where crooks attach an infected link or file.

This is why you need to be more cautious in opening emails no matter who the sender is.
