NoName (also known as CosmicBeetle) is a ransomware group active since at least 2020 targeting small and medium-sized businesses globally using its custom ScRansom tool, exploiting vulnerabilities like EternalBlue and ZeroLogon, and becoming a RansomHub affiliate to access that platform's RaaS infrastructure.

Yurei is a ransomware group first observed in September 2025 whose payload is a minimally modified fork of the open-source Prince-Ransomware, using ChaCha20 encryption and propagating across SMB shares, primarily targeting food manufacturing, transportation, and IT sectors in Sri Lanka and Nigeria.

Brotherhood is a ransomware group that emerged in late 2025, targeting organizations in the US, Canada, and Australia across manufacturing, communications, and construction sectors, operating a Tor-based double-extortion leak site.

Linkc is a ransomware group first observed in February 2025, operating a Tor-based data leak site and targeting US-based AI, cloud, aerospace, and manufacturing companies — including H2O.ai — demanding ransoms as high as $15 million using double-extortion tactics.

tuborg — tracked by MISP Galaxy (ransomware).

Insomnia is a data-theft and extortion group that emerged in October 2025, targeting primarily US-based healthcare organizations — stealing patient files and threatening public exposure rather than encrypting files — and avoiding former Soviet states, consistent with Russian-speaking cybercrime norms.

In mid-June 2024, a new ransomware operation named Brain Cipher emerged, notably targeting Indonesia's National Data Center. This attack disrupted immigration operations at airports and various other government services. The payload employed by this group is based on the leaked LockBit 3.0 builder. Comparative analyses have confirmed significant similarities between Brain Cipher and LockBit 3.0 samples. Notably, the attackers modified the ransomware to not only append a new extension to encrypted files but also to encrypt the filenames themselves. Additionally, it was identified that the group appears to be in its early stages, as evidenced by their use of the leaked LockBit 3.0 builder and their recent operations. After encrypting the data, the ransomware generates ransom notes named “added_extension.README.txt.” These notes contain a description of what occurred and a link to the attackers' website hosted on the Tor network.

JSWorm is a ransomware family that first appeared in May 2019 and is notable for undergoing multiple rebrands and evolutions, later appearing under names such as Nemty, Nefilim, Offwhite, Fusion, and Milihpen. Initially, it was distributed via malicious spam emails containing JavaScript files, hence the “JS” in its name. Later versions moved to targeted intrusions, leveraging compromised RDP services and vulnerable network appliances for initial access. JSWorm encrypts files using AES-256 encryption with RSA-2048 for key protection and appends campaign-specific extensions (e.g., .JSWORM, .Nemty, .Nephilim). The group adopted a double-extortion model in its later stages, stealing data before encryption and threatening to leak it via Tor-hosted sites. Its victimology spans various sectors worldwide, including manufacturing, energy, healthcare, and professional services. The continuous rebranding suggests an effort to evade detection, disrupt attribution, and maintain pressure on victims.

Securotrop is a ransomware group established in early 2025 that operates within the Qilin affiliate network while maintaining an independent public identity, focusing exclusively on commercial targets and deliberately avoiding healthcare and government entities, with approximately 32 documented victims.

CerBerSysLock first appeared in December 2017 as a cryptoransomware imposter, leveraging Cerber-style branding to deceive victims. It uses XOR-based encryption to lock files and appends extensions such as .CerBerSysLocked0009881. Victims receive a ransom note titled “HOW TO DECRYPT FILES.txt”, which falsely claims to be from the Cerber ransomware. The note includes an email contact—TerraBytefiles@scryptmail.com—and instructs victims to reference their ID (e.g., "CerBerSysLocked0009881") when communicating. The ransomware is technically linked to the Xorist family and is generally considered an opportunistic, low-profile scam rather than part of a broader Ransomware-as-a-Service (RaaS) operation.

Our team members are from different countries and we are not interested in anything else, we are only interested in dollars. We do not allow CIS, Cuba, North Korea and China to be targeted. Re-attacks are not allowed for target companies that have already made payments. We do not allow non-profit hospitals and some non-profit organizations be targeted.

Onyx is a ransomware group first observed in April 2022, based on the Chaos ransomware builder, that is notably destructive — files larger than 2MB are overwritten with random data rather than encrypted, making recovery impossible even after ransom payment — claiming approximately 13 victims across six countries.

The Gentlemen is a RaaS group that emerged in July–August 2025, rapidly claiming over 320 victims across 17+ countries by offering affiliates a 90% revenue share, deploying a Go-based locker against Windows, Linux, NAS, and BSD systems; a compromised C2 server in 2026 revealed more than 1,570 linked victims.

Genesis is an emerging ransomware group first observed in late 2025, targeting small to mid-sized US organizations across healthcare, retail, financial services, legal, and manufacturing using double-extortion tactics, focusing heavily on data exfiltration and public leaking.

NetWalker ransomware group operates by the threat actor known as "CIRCUS SPIDER". The NetWalker ransomware was discovered in 2019. The group mainly targeting the Asia Pacific region but can attack globally. The group uses common attacking tools like Mimikatz and other legitimate tools (LOLBINS) like PSTools, AnyDesk, TeamViewer, NLBrute, and more. The group knowing by targeting the healthcare sector. Finally, in January 2021, Netwalker was takedown by the authorities, the police have confiscated hundreds of thousands of dollars in ransom payments collected by the Netwalker group, and they seized servers and disrupted the infrastructure and the darknet websites of the Netwalker ransomware group.
