What is Maze?

There is more than one version of Maze ransomware (the previous version is also named Maze). The new version was discovered by nao_sec. Ransomware-type programs encrypt data and create ransom messages that contain information about how to decrypt files, however, victims cannot generally regain access to their files without tools held only by developers of the ransomware. This variant of Maze does not encrypt files if it detects the "C:\hutchins.txt" file on the system. If this is NOT the case, Maze encrypts files, renames them by adding a random extension (for example, "1.jpg" becomes "1.jpg.sA16PA"), creates the "DECRYPT-FILES.txt" file, and changes the desktop wallpaper.

The modified wallpaper contains a ransom message stating that the victim's files have been encrypted using RSA-2048 and ChaCha encryption algorithms. The only way to decrypt them is apparently to purchase a decryptor by following instructions provided in the "DECRYPT-FILES.txt" text file (ransom message). The message states that victims must pay the ransom through a website link, which can be opened with the Tor browser. Another way to make payment is to use another website (the link is also provided in the ransom message), which can be opened with any browser. In any case, it is made clear that victims cannot decrypt their files without the correct tool/key. The Tor website states that victims must pay $500 in Bitcoins using the BTC wallet address provided. It is mentioned that, unless victims pay the ransom within a particular time frame (a countdown timer is displayed at the top of the Tor web page), the size of the ransom is doubled. It is possible to decrypt three files free of charge through the same website. Generally, cyber criminals offer free decryption to 'prove' that they have tools/keys capable of decoding files. Despite this, people who design ransomware can never be trusted. Only they have a decryption tools/keys, however, they rarely provide these, even if victims pay the ransoms. Since there are no free tools capable of decoding files encrypted by Maze, we suggest that you restore them from a backup.

Maze decrypt instructions

This ransomware is similar to other programs of this type including, for example, Uta, MedusaLocker, and Leto. They encrypt data and create/display ransom demand messages. The main differences are usually cost of decryption tool/key and cryptographic algorithm used to encrypt data. Unfortunately, most encryptions are impossible to decrypt without using tools held only by the cyber criminals who designed the ransomware, unless the ransomware is not fully developed, contains bugs, flaws, etc. To avoid data loss caused by ransomware, maintain regular data backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer

Research shows that cyber criminals distribute Maze using SpelevoEK (exploit kit). Exploit kits are tools used to initiate 'exploits' against vulnerable (usually outdated) software or to inject malicious code into vulnerable websites. Other ways to proliferate ransomware-type programs (and other malware) are via emails, Trojans, untrustworthy software download channels, software 'cracking' tools, and fake updaters. Emails/spam campaigns can be used to infect computers through files that are attached to email messages. Typically, cyber criminals attach Microsoft Office documents, archive files (ZIP, RAR), executable files (.exe and other files of this kind), PDF documents, JavaScript files, etc. Their main goal is to trick recipients into opening the attachments. If opened, they infect systems with malware. Another way to proliferate infections is via Trojans, which are malicious programs. If already installed, they open backdoors for other malware. In this way, they cause chain infections. Examples of untrustworthy download sources are file hosting, freeware download websites, Peer-to-Peer (P2P) networks such as torrent clients, eMule, and other similar channels/tools. Cyber criminals use them to upload malicious files that are disguised as legitimate or harmless. By downloading and opening/installing them, many people install malicious programs inadvertently. Software 'cracking' tools are used by people (illegally) to avoid having to pay for activation of licensed software. In fact, these tools often install malware rather than activating any installed software free of charge. Fake (unofficial) software updating tools cause damage by exploiting bugs/flaws of outdated software that is already installed on the system, or simply by installing malicious programs rather than updates.

How to protect yourself from ransomware infections

Do not open email attachments that are presented in emails received from unknown, suspicious addresses. Typically, these are irrelevant to recipients. To trick people into opening attachments or web links, cyber criminals often present their emails as official, important. Download all software from official, trustworthy websites and via direct links. All other channels/sources mentioned above should not be trusted or used. Unofficial/third party tools that supposedly update installed software are often used to proliferate malware. Therefore, they should not be used. The safest way to update software is to use tools and functions provided by official software developers. If installed software requires activation, this should NOT be done using 'cracking' tools. They are illegal and people who use them often end up installing malicious programs. Regularly scan the operating system with reputable antivirus or anti-spyware software and keep it up-to-date. If your computer is already infected with Maze, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

Files encrypted by Maze

Update December 18, 2019 - The developers of Maze 2019 ransomware have recently started using a new method to threaten victims and to encourage them to pay ransoms. What crooks do is steal a certain amount of data with an intention making it public if the victim refuses to pay. They have developed a public website to store the stolen data of various victims. Although the developers use this tactic mainly against various businesses and companies (since these are way more likely to pay than regular users), there's no guarantee that the situation won't eventually change. At this current moment the aforementioned website contains 8 different entries.

Update May 15, 2020 - The developers of Maze ransomware have recently started looking for affiliates and offering Maze as ransomware-as-a-service (RaaS). This business model is basically based on the work distribution - the affiliate is responsible for malware distribution, while the developer provides affiliates with necessary tools to perform malicious actions. The revenue is distributed either in percentage (the developers get a certain share) or either affiliate pays a subscription fee.
