Ransomware attacks have intensified as cybercriminal groups increasingly weaponize data theft and leak sites to blackmail organizations.
Rapid7 Labs’ analysis of ransomware data from Q1 2025 reveals critical trends in the tactics of both established and emerging threat actors.
These groups are leveraging proven techniques like double extortion combining data encryption with leak threats to maximize financial gain while disrupting industries globally.
In the first quarter of 2025 alone, 80 ransomware groups were active, with 16 of them debuting.
These new entrants, including “NightSpire” and “VanHelsing,” have joined forces with prominent players like “Cl0p” and “RansomHub,” targeting essential sectors such as manufacturing, business services, healthcare, and construction.
Manufacturing was the hardest hit, accounting for 22% of leak site posts reviewed.
Geographically, traditional targets like the U.S., Canada, and Germany remain under siege, but emerging hotspots include Taiwan, Thailand, and Colombia.
Innovative Tactics: Reinvestment and Identity Shifts
Ransomware operations are evolving through strategic reinvestments and rebranding, heightening the threat landscape.
Notably, leaked chat logs from the Black Basta ransomware group have revealed evidence of cybercriminals purchasing zero-day exploits to target vulnerable systems.
An unauthenticated remote code execution (RCE) exploit for Ivanti Connect Secure was offered for $200,000, underscoring how ransomware groups reinvest ransom payments into acquiring cutting-edge tools to scale their attacks.
Additionally, Black Basta’s purchase of a root-level Juniper firewall exploit illustrates their capability to bypass traditional defenses.
Rebranding has also become common among cybercriminal groups. For instance, the resurgence of the Babuk ransomware group as “Babuk 2.0” was analyzed by Rapid7 researchers and determined to be merely repackaged operations from LockBit 3.0.
Similarly, weakened groups like FunkSec and LockBit have resorted to reusing old data and crafting fake attacks to maintain their prominence.
According to the Report, these identity shifts and data repurposing strategies serve to confuse defenders while retaining the groups’ market visibility.
Affiliates and Double Extortion Dominate Threat Strategies
Ransomware-as-a-Service (RaaS) continues to drive the proliferation of attacks, with affiliates adopting predictable yet highly effective techniques.
Double extortion remains a signature strategy, where both encrypted files and stolen data are held hostage.
Groups like Cl0p and RansomHub exemplify this approach, with Cl0p alone posting an alarming 413 leak site entries in Q1, many linked to an older vulnerability in MOVEit Transfer software.
Newer groups like Anubis are adding sophisticated layers to the double extortion model, stylizing victim data leaks as “citizen journalism” to amplify reputational damage.
By portraying their leaks as exposés of wrongdoing, Anubis aims to sway public opinion and intensify pressure on victims to pay.
The continued rise of ransomware has underscored the need for robust cybersecurity measures. Organizations must prioritize the following practices to reduce their attack surface:
- Review Multi-Factor Authentication (MFA): Ensure proper deployment and eliminate policy exceptions that weaken defenses.
- Patch Management: Focus on edge devices and known vulnerabilities critical for preventing network exploitation.
- Simulate Ransomware Attacks: Conduct regular incident response drills to improve crisis management.
- Proactively Manage Attack Surfaces: Regularly assess vulnerabilities to stay ahead of cybercriminal tactics.
As ransomware activity escalates in 2025, groups are refining their operations by reinvesting profits, rebranding identities, and adopting innovative extortion methods.
The business model underpinning ransomware attacks is thriving, aided by readily available affiliate programs and emerging groups hungry for publicity.
The deployment of advanced tools like zero-day exploits further raises the stakes for organizations.
Business leaders must confront the reality that ransomware is here to stay, reshaping cybersecurity priorities.
Without comprehensive defenses, the financial, operational, and reputational damages caused by data theft and leaks will continue to rise.
Organizations must act decisively to defend against this increasingly sophisticated threat ecosystem.
