Maze ransomware, previously known as "ChaCha", was discovered in May 2019. In addition to encrypting files on victim machines for impact, Maze operators conduct information stealing campaigns prior to encryption and post the information online to extort affected companies.[1][2][3]

Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
Maze has decrypted strings and other important information during the encryption process. Maze also calls certain functions dynamically to hinder analysis.4
Maze has inserted large blocks of junk code, including some components to decrypt strings and other important information for later in the encryption process.5
Maze operators have created scheduled tasks masquerading as "Windows Update Security", "Windows Update Security Patches", and "Google Chrome Security Update" designed to launch the ransomware.6
Maze has used WMI to attempt to delete the shadow volumes on a machine, and to connect a virtual machine to the network domain of the victim organization's network.78
Maze has used the "WNetOpenEnumW", "WNetEnumResourceW”, “WNetCloseEnum” and “WNetAddConnection2W” functions to enumerate the network resources on the infected machine.9
Maze has created scheduled tasks using name variants such as "Windows Update Security", "Windows Update Security Patches", and "Google Chrome Security Update", to launch Maze at a specific time.10
Reach is how much of ATT&CK this malware touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
