Malware

Arp

arp is a native utility used to display a host's ARP cache, which may contain address resolutions for remote systems on the local network. In the provided content, it is referenced in the context of remote system discovery and network reconnaissance rather than as a standalone malware family. The content specifically notes that arp can be used to display ARP cache entries for remote systems, and that BlackByte used Arp to identify remotely connected devices. Related examples in the same context also note use of ARP-table-based discovery by other malware such as Diavol. No additional malware-specific infection vector, persistence mechanism, payload behavior, or industry targeting is directly provided for arp in the source content.

MITRE ATT&CK

Techniques & procedures

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

Discovery

2 techniques

T1016System Network Configuration DiscoveryEvidence7

AdFind can extract subnet information from Active Directory; actors used ipconfig /all after exploiting a machine; numerous malware and groups used ipconfig, ifconfig, arp, route, netsh, nbtstat, NBTscan, and related APIs to gather IP, MAC, DNS, DHCP, gateway, proxy, domain, ARP cache, routing, and adapter details.

T1018Remote System DiscoveryEvidence1

During the 2015 Ukraine Electric Power Attack, Sandworm Team remotely discovered systems over LAN connections. OT systems were visible from the IT network as well, giving adversaries the ability to discover operational assets.
