Cl0p, LockBit, ALPHV: The Modern Ransomware Ecosystem in 2026

Published on 2026-04-118 min readFlorian

Ransomware Is an Industry

Ransomware is no longer the work of isolated individuals. It is a structured industrial ecosystem built around the Ransomware-as-a-Service (RaaS) model. Developers create the malware and infrastructure, affiliates conduct attacks, and revenue is shared. In 2026, this ecosystem continues to evolve despite law enforcement operations.

The RaaS Model

Ransomware-as-a-Service works like a franchise model:

  • Operators develop the ransomware, maintain infrastructure (negotiation sites, payment portals, leak sites), and provide technical support
  • Affiliates purchase ransomware access, conduct attacks (intrusion, lateral movement, exfiltration, deployment), and negotiate with victims
  • Revenue sharing: typically 20-30% for the operator, 70-80% for the affiliate
  • Cl0p: The Zero-Day Exploitation Specialist

    Cl0p (also written Clop) distinguishes itself through strategy: rather than encrypting data, it steals data via zero-day vulnerabilities in file transfer software.

    Major operations:

  • Accellion FTA (2021): exploitation of vulnerabilities in Accellion File Transfer Appliance
  • GoAnywhere MFT (2023): CVE-2023-0669, hit 130+ organizations
  • MOVEit Transfer (2023): CVE-2023-34362, hit 2,500+ organizations
  • Distinction: Cl0p does not encrypt systems. It exfiltrates data and threatens to publish it. This is pure extortion, without the traditional ransomware component. This approach is faster and does not require deploying persistent malware.

    LockBit: The Most Prolific

    LockBit was the most active ransomware group between 2022 and 2024, claiming more victims than any other group. In February 2024, Operation Cronos (Europol, FBI, NCA) dismantled part of its infrastructure, but the group attempted to relaunch.

    Characteristics:

  • Very open affiliate program (low entry barrier)
  • Fast encryption (LockBit 3.0 uses speed-optimized ransomware)
  • Bug bounty program for its own malware
  • Systematic double extortion (encryption + data theft)
  • After Cronos: LockBit lost affiliate trust. Many migrated to other platforms. In 2026, the group attempts to maintain relevance but its influence has diminished.

    ALPHV/BlackCat: The Technical Innovator

    ALPHV (also known as BlackCat) distinguished itself through technical innovation: first major ransomware written in Rust (faster, harder to analyze), first use of a leak site with a searchable API, and first publication of stolen data via a clone of the victim's website.

    Controversial end: in December 2023, the FBI seized ALPHV's infrastructure. The group attempted to relaunch, then in March 2024, after receiving a $22 million ransom from Change Healthcare, ALPHV performed an "exit scam" by shutting down its infrastructure and keeping the money, leaving its affiliates unpaid.

    Evolution in 2026

    Toward encryption-free extortion: more groups are adopting the Cl0p model. Stealing data is faster and more discreet than encrypting systems.

    Fragmentation: after law enforcement operations, large groups fragment into smaller, more agile entities.

    SMB targeting: large enterprises invest in security. SMBs become easier and more numerous targets.

    Defenses

    3-2-1 backup: 3 copies, 2 different media, 1 offsite and offline.

    Exfiltration detection: monitor unusual data transfers (volume, destination, timing).

    Network segmentation: limit lateral movement. Ransomware that compromises one workstation should not be able to reach critical servers.

    Patching exposed services: groups like Cl0p exploit known vulnerabilities in internet-accessible services.

    Regular security auditing is the best prevention against ransomware. CleanIssue identifies the attack surfaces that ransomware groups target first.
