A New Era in Ransomware Tactics
Bridewell, a prominent UK-based cybersecurity firm, has just published its highly anticipated CTI Annual Report, and it signals a major transformation in the cyber threat landscape. Ransomware, long associated with file encryption and demands for payment, is now evolving rapidly. The report reveals that the most effective attacks are no longer the ones that lock up systems, but those that threaten to leak sensitive data. With regulatory scrutiny at an all-time high and reputational risk escalating, this change in tactics is proving more successful for cybercriminals. Simultaneously, stricter international sanctions and increased law enforcement collaboration are changing how organizations respond to ransom demands.
The Shift in Cybercriminal Strategy
Bridewell’s report uncovers a stark evolution in ransomware techniques. While traditional encryption-based attacks still exist and can demand large sums for decryption, they’re increasingly overshadowed by data theft and extortion schemes. These operations involve stealing confidential data and threatening public exposure unless payment is made. Organizations are more inclined to pay in these scenarios, driven by fears of regulatory violations, fines, and public fallout. Interestingly, while these data-centric attacks are on the rise, overall ransom payments are on the decline — a sign of mounting external pressures and legal complexities.
Bridewell attributes this decrease in payouts to tighter regulations, better international coordination between law enforcement bodies, and targeted sanctions against known Ransomware-as-a-Service (RaaS) groups. Companies must now perform detailed due diligence before making any payment, ensuring they do not fund sanctioned entities or risk legal consequences.
The report highlights an alarming rise in the exploitation of internet-facing systems and unpatched vulnerabilities, especially in commonly used platforms like Fortinet and Ivanti. Sophisticated groups such as Clop and Termite are using these weaknesses to launch wide-scale attacks. The landscape is becoming increasingly chaotic as major ransomware groups fragment due to internal strife and law enforcement disruption, giving rise to a wave of lone-wolf actors. These individuals, often working independently with access to leaked tools, are unpredictable and harder to track.
Bridewell also notes a tactical pivot toward targeting critical infrastructure, especially virtualized environments like VMware ESXi. Actors such as VanHelsing and DragonForce are focusing on paralyzing virtual servers to maximize pressure on victims. In parallel, there’s a growing trend of attackers bypassing traditional defenses using sophisticated tools like Cobalt Strike, Sliver, and Pyramid C2. Many now rely on stealth tactics such as Living-Off-the-Land Binaries (LOLBINs) and Remote Monitoring and Management (RMM) tools to maintain control without setting off alarms.
A particularly concerning development is the move toward pure data-theft operations, entirely skipping encryption. These attacks exploit today’s data protection regulations, where the threat of exposure carries heavier consequences than downtime. Remote access tools and poor patch management remain prime entry points, with phishing playing a smaller, more indirect role via credential sales.
What Undercode Say:
A Landscape Shaped by Regulation and Reputational Risk
Bridewell’s findings underscore a pivotal transformation in cybercrime strategy, where pressure points have shifted from operational paralysis to reputational and regulatory damage. The move from encryption-only to data theft-extortion operations reflects the modern attacker’s understanding of enterprise psychology. In today’s compliance-heavy environment, the fear of breaching GDPR or similar laws often outweighs the cost of restoring IT systems. This makes companies more vulnerable to blackmail when their confidential data is at stake.
Fragmentation Spurs Chaos
The fragmentation of once-dominant ransomware groups such as Conti and AlphV/BlackCat has decentralized the threat ecosystem. This decentralization creates an unstable battlefield, with a wider range of actors and less predictability. Lone wolves using recycled tools and codes introduce further volatility, especially as they act independently, with fewer operational constraints. These actors are often just as technically capable and are driven by opportunism rather than structured goals, making them harder to defend against.
Rise of Vulnerability Exploitation
Bridewell’s emphasis on vulnerability exploitation reveals a crucial gap in cybersecurity readiness. The exploitation of known flaws in platforms like Fortinet and Ivanti points to a continued failure in timely patch management. This negligence allows actors to scale their attacks effectively, increasing both reach and profitability. Many of these breaches could be prevented through better configuration, monitoring, and regular updates.
The Vanishing Boundary Between Tools and Threats
Modern ransomware campaigns now blend in with legitimate administrative operations, blurring the lines between normal activity and threat behavior. The use of RMM tools and LOLBINs allows attackers to mimic legitimate system processes, reducing detection likelihood. The popularity of frameworks like Cobalt Strike or Pyramid C2 is particularly concerning because it democratizes access to professional-grade offensive tooling.
Virtual Infrastructure in the Crosshairs
Targeting VMware ESXi environments is not just technically sophisticated — it’s a strategic decision. These systems often host multiple mission-critical applications, and their compromise has a domino effect across business operations. Attacking virtual layers allows ransomware groups to multiply the pain point, pushing organizations toward quicker resolutions — or payments.
Regulatory Complexity Curtails Payments
A key reason behind the decline in overall ransom payments is not just resistance or improved security — it’s legal entanglement. Sanctions on groups and wallets associated with cybercrime mean that even considering payment now requires legal review, external consultation, and board-level risk assessment. This bureaucratic burden is helping to stall the traditional “pay to recover” response many organizations defaulted to in the past.
Phishing Declines But Credentials Still Matter
Bridewell’s findings that phishing is becoming less frequent should not be misinterpreted as a reduction in social engineering threats. Instead, credentials are being commoditized and sold by access brokers, shifting the entry point further up the supply chain. This arms ransomware affiliates with clean, ready-to-use credentials — often with elevated access — making initial breaches even faster and more dangerous.
Data Theft is the Future of Ransomware
With fines for privacy violations increasing and brand reputation more fragile than ever, the shift to non-encrypting ransomware is logical. These campaigns cost less to execute, leave fewer forensic traces, and exploit deeper psychological and business vulnerabilities. Bridewell rightly highlights this trend as one that security teams must take seriously — not just as a possibility, but as the prevailing threat in 2025.
🔍 Fact Checker Results:
✅ Data-theft and extortion are now more successful than encryption-only ransomware
✅ Ransomware payments have declined due to regulatory risk and sanctions
✅ Lone-wolf and fragmented threat actors are rising in prevalence
📊 Prediction:
Ransomware in 2025 and beyond will continue to evolve toward stealth, scalability, and psychological pressure. Expect to see more data-centric campaigns, smaller independent actors, and deeper penetration of IT infrastructure using legitimate admin tools. Organizations that fail to prioritize patching, restrict remote access, and detect behavioral anomalies will face higher risk. Data loss, not downtime, will soon be the dominant fear driving security investment.
