Maoloa ransomware removal instructions
What is Maoloa?
Discovered by S!Ri, Maoloa is a malicious program categorized as ransomware. Once it has infiltrated the system, Maoloa encrypts all files stored on the computer and generates a ransom-demand message called "HOW BACK YOUR FILES.txt". It also renames all encrypted files by adding a new/additional ".maoloa" extension. For example, "1.jpg" becomes "1.jpg.maoloa". Updated variants of this ransomware add ".shelbyboom" extension to encrypted files.
The ransom demand message ("HOW BACK YOUR FILES.txt" file) states that all files have been encrypted and to retrieve them (obtain a decryption tool), affected users must contact these cyber criminals using one of the following email addresses: email@example.com, firstname.lastname@example.org, or email@example.com. The email must include the assigned personal ID. Receipt of this email indicates a willingness for Maoloa victims to pay the ransom - effectively, buy a decryption tool. It is possible to send them two files for free decryption before purchasing the tool. Cyber criminals offer this as 'proof' that they have the correct tool capable of decryption. Victims with computers infected with this ransomware are warned not to rename any of the encrypted files or make attempts to decrypt them using other (third party) tools. According to these developers, such attempts might result in permanent data loss. Note that most cyber criminals (ransomware developers) employ cryptographies (symmetric or asymmetric) that are impossible to 'crack' without the correct tool. Generally, only ransomware developers have these tools. Despite this, do not purchase any tools from these people - most cyber criminals do not send any tools even when their ransom demands are met and payments are made. Therefore, most people are scammed. The best free choice in these situations is to use a data backup created before encryption and to recover files from there.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type programs share two main similarities: they encrypt data stored on computers and allow developers to make ransom demands. Common differences are cost of decryption (via a decryption tool) and cryptography algorithm employed to encrypt files. Most of these programs are quite similar. Unfortunately, most are impossible to 'crack' without the involvement of the developers, or when the ransomware contains bugs/flaws or is still in development. Therefore, maintain data backups at regular intervals and store them on remote servers or unplugged storage devices. Some examples of other ransomware-type programs are .blower, CryptoID, and 888.
How did ransomware infect my computer?
It is difficult to determine exactly how developers proliferate Maoloa, however, most use spam campaigns (emails), Trojans, unofficial software download channels, software cracking tools and fake software updaters. Ransomware and other infections are proliferated through spam campaigns by sending emails that contain malicious attachments. These attachments are various files such as Microsoft Office documents, PDF files, archive files (such as RAR, ZIP), executables (.exe files), and so on. The main objective of these campaigns is to trick people (recipients) into opening these attachments. Opening them usually results in download and installation of high-risk infections such as ransomware-type programs. Trojans are malicious programs that cause chain infections (they proliferate other programs of this type). To do so, however, they must first be installed. Untrustworthy, dubious software download sources such as freeware download websites, free file hosting sites, peer-to-peer networks (torrents, eMule etc.) third party software downloaders and other such tools are used to infected computers. Cyber criminals present their malicious programs as legitimate and use dubious tools to install computer infections rather than the chosen software. By using software cracking tools, many people cause computer infections. These tools are supposedly capable of activating software or operating systems free of charge (without paying for activation), however, cyber criminals design these tools to install malicious program rather than activating any software. Fake software updaters cause damage by downloading malware rather than the promised updates, or by exploiting bugs/flaws of the outdated software (a similar strategy to software cracking tools).
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Maoloa virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Download, install, update software, and browse the web with care. Avoid using third party software downloaders/installers, unofficial websites, Peer-to-Peer networks, and other such tools. Download software using only official and trustworthy websites (or other reliable channels). Update installed software using implemented functions or tools provided by official software developers. Be careful with opening attachments (or web links) that are presented in emails received from unknown/suspicious email addresses. Do not open them if they seem suspicious. Software cracking tools are illegal and often cause computer infections. Therefore, do not use them. Having reputable anti-spyware/anti-virus software installed and keeping it enabled is is good prevention against various computer infections. These tools can detect threats and eliminate then before any damage is done. If your computer is already infected with Maoloa, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
