MITRE ATT&CK

Techniques & procedures

5 distinct techniques documented for this family, organized by ATT&CK tactic.

Stealth

3 techniques

T1027.002Software PackingEvidence1

Diicot payloads use a modified UPX packer that changes the magic header from "UPX!" to "YTS\x99" and corrupts checksum information.

T1027.009Embedded PayloadsEvidence1

The Update payload drops two additional embedded malicious files; abc123 also contains a version of Update as an embedded binary payload.

T1497.003Time Based ChecksEvidence1

If the malware detects it is running within a cloud environment, as determined by Linux distribution and version, it prioritizes spreading; non-cloud systems may receive cryptomining payloads.

Discovery

2 techniques

T1082System Information DiscoveryEvidence1

Update checks Linux distribution and version, while successful brute-force reports include CPU count, hostname, architecture, kernel version, and GPU availability.

T1497.003Time Based ChecksEvidence1

If the malware detects it is running within a cloud environment, as determined by Linux distribution and version, it prioritizes spreading; non-cloud systems may receive cryptomining payloads.

Impact

1 technique

T1496.001Compute HijackingEvidence1

The abc123 payload contains a custom version of XMRig with built-in configuration and references to mining pools; the group is assessed to mine Monero and Zephyr.

Unpacking the Diicot Malware Targeting Linux Environments | Wiz Blog

Linux cryptomining payload aimed at non-cloud environments. It incorporates an embedded Update payload for propagation and a custom XMRig-based miner configured for Monero mining, with evidence of Zephyr mining infrastructure as well.
