T1686: Disable or Modify System Firewall

Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic. For example, this may include turning off firewall profiles, altering existing rules to permit previously blocked ports or protocols, or adding new rules that create covert communication paths (e.g., adding a new firewall rule for a well-known protocol (such as RDP) using a non-traditional and potentially less securitized port.[1]

Adversaries may disable or modify firewalls using different behaviors, depending on the platform. For example, in ESXi, firewall rules may be modified directly via the esxcli (e.g., via esxcli network firewall set) or via the vCenter user interface.[2][3]

Glexia's Take · Automated analysis

Security context for executives and security teams

Automation confidenceHigh

Disabling or changing firewalls is a direct attack on the controls that keep systems, virtual infrastructure, and network devices segmented and observable. For leaders, the significance is not just “a firewall was changed,” but that an adversary with sufficient privileges may be preparing to move laterally, open remote access paths, bypass egress restrictions, or reduce the organization’s ability to contain an incident.

Executive priority

Treat this as a high-priority defense-impairment behavior because it can undermine business continuity and incident containment across Windows, Linux, macOS, ESXi, and network devices. Executives should ask whether firewall rule changes are approved, logged, reviewed, and rapidly reversible—especially on virtualization hosts, perimeter/network devices, and systems supporting critical operations. This technique also has compliance relevance: audit evidence should show who changed firewall policy, when, from where, and under what authorization.

Technical view

SOC, detection engineering, and IR teams should validate monitoring for firewall service state changes, profile changes, rule additions/deletions/modifications, and configuration changes across the supported platforms. The ESXi reference specifically highlights firewall modification via esxcli or the vCenter user interface; Windows-related relationship context points to host firewall profile and rule changes. Relationship context also shows sub-techniques for Network Device Firewall and Windows Host Firewall, so detections should not be limited to endpoint logs alone. DET0145 is listed as a related detection strategy, but the ATT&CK object itself provides no official detection text, so local validation is required.

Likely telemetry

  • Endpoint security and operating system logs showing firewall service state or policy changes
  • Windows host firewall rule/profile change logs where available
  • Linux and macOS firewall configuration and command/audit logs
  • ESXi host and vCenter administrative activity logs, including firewall configuration changes
  • Network device configuration change logs for ACLs, zones, and policy rules

Detection direction

  • Baseline expected firewall rules and alert on unauthorized additions, deletions, disabled profiles, or broad permit rules.
  • Correlate firewall changes with privileged account use, remote administration, suspicious timing, and subsequent network connections.
  • Cover both host-based and network-device firewalls; a common blind spot is focusing only on Windows endpoints while missing ESXi, Linux/macOS, and infrastructure device changes.
  • Tune for legitimate administrative maintenance by joining detections to change tickets or approved automation accounts rather than suppressing firewall-change alerts globally.
  • Prioritize changes that enable remote access protocols, unusual ports, unrestricted internal access, or outbound paths that were previously blocked.

Mitigation priorities

  • Enforce least privilege and strong user account management for accounts capable of changing firewall settings.
  • Restrict file, directory, and registry permissions where firewall configuration can be modified through local system artifacts.
  • Audit firewall configuration changes across endpoints, ESXi/vCenter, and network devices, and retain logs long enough for incident response and compliance review.
  • Require change control and independent review for firewall rule changes on critical systems and network infrastructure.
  • Maintain known-good firewall configurations and recovery procedures so incident responders can quickly identify and reverse unauthorized changes.
Additional notes and limits

This technique is newly represented as T1686 in ATT&CK release 19.1 and is the successor for revoked T1562.004 based on the supplied relationship. Reported relationships include multiple groups, campaigns, and software using this behavior, including SolarWinds Compromise, Leviathan Australian Intrusions, Carbanak, Dragonfly, FIN7, APT38, Kimsuky, TeamTNT, BlackByte, Salt Typhoon, Velvet Ant, UNC3886, Medusa Group, and PlugX. These relationships support defensive prioritization but should not be used alone for attribution.

The official ATT&CK object does not provide detection text, and the supplied fields do not define platform-specific event IDs, commands, or guaranteed indicators. Detection quality depends on local logging, administrative workflows, device coverage, and whether firewall changes are centrally collected and correlated with identity and change-management data.

GroupEnterprise

G0139: TeamTNT

TeamTNT is a threat group that has primarily targeted cloud and containerized environments. The group as been active since at least October 2019 and has mainly focused its efforts on leveraging cloud and container resources to deploy cryptocurrency miners in victim environments.[1][2][3][4][5][6][7][8][9]

GroupEnterprise

G1022: ToddyCat

ToddyCat is a sophisticated threat group that has been active since at least 2020 using custom loaders and malware in multi-stage infection chains against government and military targets across Europe and Asia.[1][2]

GroupEnterprise

G1043: BlackByte

BlackByte is a ransomware threat actor operating since at least 2021. BlackByte is associated with several versions of ransomware also labeled BlackByte Ransomware. BlackByte ransomware operations initially used a common encryption key allowing for the development of a universal decryptor, but subsequent versions such as BlackByte 2.0 Ransomware use more robust encryption mechanisms. BlackByte is notable for operations targeting critical infrastructure entities among other targets across North America.[1][2][3][4][5]

GroupEnterprise

G1047: Velvet Ant

Velvet Ant is a threat actor operating since at least 2021. Velvet Ant is associated with complex persistence mechanisms, the targeting of network devices and appliances during operations, and the use of zero day exploits.[1][2]

GroupEnterprise

G1051: Medusa Group

Medusa Group has been active since at least 2021 and was initially operated as a closed ransomware group before evolving into a Ransomware-as-a-Service (RaaS) operation. Some reporting indicates that certain attacks may still be conducted directly by the ransomware’s core developers. Public sources have also referred to the group as “Spearwing” or “Medusa Actors.” [1] [2] Medusa Group employs living-off-the-land techniques, frequently leveraging publicly available tools and common remote management software to conduct operations. The group engages in double extortion tactics, exfiltrating data prior to encryption and threatening to publish stolen information if ransom demands are not met. [3] For initial access, Medusa Group has exploited publicly known vulnerabilities, conducted phishing campaigns, and used credentials or access purchased from Initial Access Brokers (IABs). The group is opportunistic and has targeted a wide range of sectors globally. [4]

GroupEnterprise

G0082: APT38

APT38 is a North Korean state-sponsored threat group that specializes in financial cyber operations; it has been attributed to the Reconnaissance General Bureau.[1] Active since at least 2014, APT38 has targeted banks, financial institutions, casinos, cryptocurrency exchanges, SWIFT system endpoints, and ATMs in at least 38 countries worldwide. Significant operations include the 2016 Bank of Bangladesh heist, during which APT38 stole $81 million, as well as attacks against Bancomext [2] and Banco de Chile [2]; some of their attacks have been destructive.[1][2][3][4]

North Korean group definitions are known to have significant overlap, and some security researchers report all North Korean state-sponsored cyber activity under the name Lazarus Group instead of tracking clusters or subgroups.

GroupEnterprise

G0046: FIN7

FIN7 is a financially-motivated threat group that has been active since 2013. FIN7 has targeted the retail, restaurant, hospitality, software, consulting, financial services, medical equipment, cloud services, media, food and beverage, transportation, pharmaceutical, and utilities industries in the United States. A portion of FIN7 was operated out of a front company called Combi Security and often used point-of-sale malware for targeting efforts. Since 2020, FIN7 shifted operations to big game hunting (BGH), including use of REvil ransomware and their own Ransomware-as-a-Service (RaaS), Darkside. FIN7 may be linked to the Carbanak Group, but multiple threat groups have been observed using Carbanak, leading these groups to be tracked separately.[1][2][3][4][5][6][7]

GroupEnterprise

G0035: Dragonfly

Dragonfly is a cyber espionage group that has been attributed to Russia's Federal Security Service (FSB) Center 16.[1][2] Active since at least 2010, Dragonfly has targeted defense and aviation companies, government entities, companies related to industrial control systems, and critical infrastructure sectors worldwide through supply chain, spearphishing, and drive-by compromise attacks.[3][4][5][6][7][8][9]

GroupEnterprise

G0094: Kimsuky

Kimsuky is a Democratic People's Republic of Korea (DPRK)-based cyber espionage group that has been active since at least 2012. The group initially targeted South Korean government agencies, think tanks, and subject-matter experts in various fields. Its operations expanded to include the United Nations and organizations in the government, education, business services, and manufacturing sectors across the United States, Japan, Russia, and Europe. Kimsuky has focused collection on foreign policy and national security issues tied to the Korean Peninsula, nuclear policy, and sanctions. Kimsuky operations have overlapped with those of other North Korean state-sponsored cyber espionage actors as a result of ad hoc collaborations or other limited resource sharing.[1][2][3][4][5][6]

Kimsuky was assessed to be responsible for the 2014 Korea Hydro & Nuclear Power Co. compromise; other notable campaigns include Operation STOLEN PENCIL (2018), Operation Kabar Cobra (2019), and Operation Smoke Screen (2019).[7][8][9] In 2023, Kimsuky was observed using commercial large language models (LLMs) to assist with vulnerability research, scripting, social engineering and reconnaissance.[10]

DPRK threat actor cluster boundaries overlap in open source reporting, with some security researchers consolidating all attributed North Korean state-sponsored cyber activity under Lazarus Group, rather than tracking operationally distinct subgroups.

GroupEnterprise

G0106: Rocke

Rocke is an alleged Chinese-speaking adversary whose primary objective appeared to be cryptojacking, or stealing victim system resources for the purposes of mining cryptocurrency. The name Rocke comes from the email address "rocke@live.cn" used to create the wallet which held collected cryptocurrency. Researchers have detected overlaps between Rocke and the Iron Cybercrime Group, though this attribution has not been confirmed.[1]

C0049: Leviathan Australian Intrusions

Leviathan Australian Intrusions consisted of at least two long-term intrusions against victims in Australia by Leviathan, relying on similar tradecraft such as external service exploitation followed by extensive credential capture and re-use to enable privilege escalation and lateral movement. Leviathan Australian Intrusions were focused on exfiltrating sensitive data including valid credentials for the victim organizations.[1]

CampaignEnterprise

C0024: SolarWinds Compromise

The SolarWinds Compromise was a sophisticated supply chain cyber operation conducted by APT29 that was discovered in mid-December 2020. APT29 used customized malware to inject malicious code into the SolarWinds Orion software build process that was later distributed through a normal software update; they also used password spraying, token theft, API abuse, spear phishing, and other supply chain attacks to compromise user accounts and leverage their associated access. Victims of this campaign included government, consulting, technology, telecom, and other organizations in North America, Europe, Asia, and the Middle East. This activity has been labled the StellarParticle campaign in industry reporting.[1] Industry reporting also initially referred to the actors involved in this campaign as UNC2452, NOBELIUM, Dark Halo, and SolarStorm.[2][3][4][5][1][6][7][8]

In April 2021, the US and UK governments attributed the SolarWinds Compromise to Russia's Foreign Intelligence Service (SVR); public statements included citations to APT29, Cozy Bear, and The Dukes.[9][10][11] The US government assessed that of the approximately 18,000 affected public and private sector customers of Solar Winds’ Orion product, a much smaller number were compromised by follow-on APT29 activity on their systems.[12]
