Threat actor profile: LockBit
Threat actor status: ACTIVE
Since first appearing in September 2019 under the name "ABCD," LockBit has grown into one of the most prolific ransomware operations in the world, targeting organisations across healthcare, finance, manufacturing, education and government. Active globally and observed directly by Triskele Labs across eleven incident response engagements in Australia, the group operates under a ransomware-as-a-service (RaaS) model and has built a reputation for speed, customisation and reliability that keeps it a preferred choice for affiliates across the ransomware ecosystem.
LockBit: Background
LockBit first appeared in September 2019 under the name "ABCD" and has since rebranded twice, first as LockBit 2.0 in 2021 and later as LockBit 3.0 in mid-2022. Under its ransomware-as-a-service model, the group provides affiliates with access to its encryption and decryption tools, backend portals and technical support in exchange for a share of ransom payments.
LockBit is best known for double extortion, exfiltrating data before encrypting victim environments and leveraging the threat of public leaks to pressure payment. In some cases, affiliates have gone further still, layering on triple extortion by threatening distributed denial-of-service (DDoS) attacks or contacting a victim's customers and business partners directly.
The group has predominantly targeted organisations in the United States, the United Kingdom, Germany, France and Australia. Its activity surged following the outbreak of the Russia-Ukraine conflict, and it has consistently ranked among the most active ransomware operators worldwide. Despite law enforcement crackdowns and occasional leaks of its builder tools, LockBit has shown resilience, regularly adapting its infrastructure and continuing to expand its affiliate base.
How LockBit Operates
Across the eleven incidents responded to by Triskele Labs, a consistent and methodical pattern of compromise emerged.
Initial Access: VPN, RDP and Weak Credential Exploitation
LockBit affiliates rely heavily on exploiting external-facing services and weak credentials to gain initial access. This includes exploiting vulnerabilities in VPN appliances and Remote Desktop Protocol (RDP), a Microsoft technology that allows a user to connect to and control a remote computer as though sitting in front of it, alongside brute force and password spraying attacks against exposed services to establish a foothold.
Credential Access: Credential Harvesting with Mimikatz
Once inside, LockBit affiliates use Mimikatz, a post-exploitation tool that extracts plaintext passwords, hashes and Kerberos tickets from Windows memory, to harvest stored credentials after gaining access to the victim network. This escalates their access and supports further movement through the environment.
Discovery: Network and Domain Enumeration
LockBit affiliates map the environment before moving further, using Netscan and Advanced Port Scanner to scan the internal network for live hosts, open ports and potential targets. AdFind, a command-line tool for querying Active Directory, is used to locate domain controllers and gather information about the victim's environment.
Lateral Movement: PsExec and RDP
With domain information and harvested credentials in hand, LockBit affiliates move laterally using PsExec, a remote administration utility that allows attackers to execute processes on other systems without physical access, and RDP itself, reusing the same protocol exploited for initial access to traverse the network.
Persistence: Remote Access Software
LockBit affiliates maintain persistence in compromised environments using remote access software, including tools such as AnyDesk, TightVNC, Splashtop and ScreenConnect, legitimate remote desktop applications repurposed to give attackers ongoing, low-visibility control.
Defence Evasion: Group Policy Abuse
LockBit affiliates weaken endpoint security by modifying or disabling Windows Defender through Group Policy Objects (GPOs), a Windows feature allowing administrators to define and enforce settings across all systems in an organisation from a central location. Abusing GPOs in this way strips out the primary line of endpoint defence across the environment in one action.
Exfiltration: Data Exfiltration via Rclone
Before deploying ransomware, LockBit affiliates exfiltrate sensitive data to maximise leverage for double extortion. Rclone, a command-line tool for managing and syncing files across cloud storage providers, is used to transfer stolen data to public cloud file-sharing services such as MEGAsync or FileZilla.
Impact: Encryption and Extortion Escalation
With data already exfiltrated, LockBit deploys its encryption payload across the environment. Victims are then pressured through double extortion, and in some cases triple extortion, with affiliates threatening DDoS attacks or directly contacting a victim's customers and business partners to increase pressure to pay.
LockBit: Reducing your exposure
The consistent entry points and techniques observed across LockBit engagements mean there are clear, actionable controls that reduce risk materially.
-
Enforce MFA across all external-facing services without exception.
LockBit's most common entry point is an exposed VPN or RDP service without MFA, often paired with brute force or password spraying. MFA closes off this vector even where credentials have been compromised elsewhere. -
Patch VPN and remote access infrastructure promptly.
LockBit affiliates exploit known vulnerabilities in VPN appliances as a primary entry method. A documented patch management programme with defined timelines for critical patches reduces the window of exposure on internet-facing infrastructure. -
Restrict and monitor RDP within the internal network.
LockBit uses RDP for both initial access and lateral movement. Limit RDP access to only the systems and accounts that require it, enforce strong authentication for all sessions, and monitor for activity outside normal patterns. -
Deploy and maintain EDR across every endpoint and server, with tamper protection enabled.
LockBit affiliates deliberately target Windows Defender through Group Policy abuse. Endpoint Detection and Response (EDR) with tamper protection prevents security tooling from being disabled by an unauthorised process. -
Monitor for anomalous use of legitimate remote access and administration tools.
Because LockBit relies on remote access software and administration utilities already trusted in many environments, detection needs to focus on unusual usage patterns, not just known-bad signatures. -
Monitor for exfiltration tooling and anomalous outbound data volumes.
LockBit uses Rclone to move stolen data to cloud storage ahead of encryption. Build detections for unexpected use of cloud sync tooling combined with unusual outbound data volumes, particularly outside business hours. -
Ensure security alerting is monitored around the clock.
Whether through an internal security operations capability or an external managed detection and response (MDR) provider, continuous monitoring closes the gap between initial access and full encryption.
Summary
LockBit is an active, financially motivated ransomware group operating under a ransomware-as-a-service model since 2019, having rebranded twice to reach its current LockBit 3.0 iteration. Triskele Labs has responded directly to eleven LockBit incidents, the highest engagement count of any group in this series, giving firsthand insight into a consistent pattern: gain initial access through an exposed VPN or RDP service, harvest credentials with Mimikatz, enumerate the network and domain, move laterally via PsExec and RDP, persist using legitimate remote access software, disable Windows Defender through Group Policy abuse, exfiltrate data via Rclone, then encrypt and escalate through double or triple extortion.
The defences most likely to disrupt a LockBit intrusion are foundational: enforce MFA on every external-facing service, patch VPN and remote access infrastructure promptly, restrict RDP internally, and keep EDR tamper-protected and consistently deployed. LockBit's dominance comes from reliability and scale, not technical novelty. It succeeds because the environments it targets have not applied the controls that would stop it at the door.
If your organisation has experienced a LockBit incident or suspects a compromise involving ransomware or data exfiltration, engage your cyber insurer and a reputable DFIR firm promptly.
