A New Cybercrime Giant Emerges From the Shadows
The ransomware ecosystem never stays still. When one criminal empire falls, another quickly moves to occupy the vacuum. Over the past two years, the cybersecurity industry has witnessed exactly that phenomenon as the INC ransomware group transformed from a relatively unknown operation into one of the most active and dangerous ransomware organizations on the planet.
While many cybercriminal groups attempt to gain attention through sophisticated malware, cutting-edge exploits, or highly innovative attack methods, INC took a completely different path. Instead of reinventing cybercrime, it perfected the fundamentals. The group focused on exploiting human error, unpatched systems, stolen credentials, and industries where operational downtime can become catastrophic within hours.
This straightforward strategy has proven devastatingly effective. Since emerging in 2023, INC has reportedly claimed more than 800 victims worldwide, establishing itself as a dominant force in the ransomware-as-a-service (RaaS) market. Its rise highlights a disturbing reality facing organizations today: attackers do not necessarily need advanced technology to cause massive damage. Consistency, scalability, and targeting the right victims can be equally powerful.
The Collapse of Major Ransomware Groups Created an Opportunity
The ransomware landscape experienced major disruptions after the decline of notorious groups such as ALPHV/BlackCat and LockBit. Law enforcement operations, infrastructure seizures, affiliate uncertainty, and operational disruptions weakened several dominant ransomware brands that had controlled large portions of the cybercriminal marketplace.
As these groups struggled, INC emerged at precisely the right moment.
The timing was almost perfect. Affiliates seeking new opportunities needed stable ransomware operations. Criminal actors looking for alternative platforms wanted dependable malware and reliable profit-sharing systems. INC provided exactly that.
Rather than competing through innovation, the group capitalized on instability within the criminal ecosystem. By attracting affiliates displaced from larger operations, INC rapidly expanded its reach and operational capacity.
This strategy mirrors how legitimate businesses often grow during market disruptions. The difference is that INC operates entirely within the cybercriminal underground.
Why Healthcare Became a Prime Target
One of the most concerning aspects of
Hospitals, healthcare providers, and medical institutions represent some of the most vulnerable targets in modern cybersecurity. Unlike many businesses, healthcare organizations cannot simply pause operations while systems are restored.
Patient care depends on constant access to digital records, diagnostic equipment, scheduling systems, laboratory results, and communication platforms. Every minute of downtime can affect real-world medical outcomes.
INC appears to understand this pressure exceptionally well.
The group has reportedly targeted organizations such as the healthcare provider NHS Dumfries & Galloway in Scotland and Alder Hey Children’s Hospital in Liverpool. These incidents demonstrate a strategic focus on institutions where disruption creates immediate urgency.
For ransomware operators, urgency often translates into leverage. The more critical the service, the greater the pressure to restore operations quickly, creating stronger incentives for victims to negotiate or pay.
Sensitive Data Has Become a Powerful Weapon
Modern ransomware is no longer limited to encrypting files.
INC follows the increasingly common double-extortion model. Under this approach, attackers not only encrypt systems but also steal sensitive information before locking victims out.
If a victim refuses to pay for decryption, the attackers threaten to publish or sell the stolen data.
For healthcare providers, law firms, educational institutions, and technology companies, this threat can be devastating. Confidential patient records, legal documents, intellectual property, financial data, and internal communications become bargaining chips.
This dual-pressure strategy significantly increases the chances of successful extortion because victims must worry about both operational disruption and reputational damage.
The Power of Simple Intrusion Techniques
Many organizations imagine ransomware attacks involving advanced nation-state-level hacking techniques. The reality is often far less glamorous.
INC relies heavily on proven intrusion methods that have worked for years.
Spearphishing remains one of the
The group also benefits from stolen credentials obtained through Initial Access Brokers, criminal intermediaries who specialize in selling access to compromised networks.
Additionally, INC actively exploits well-known vulnerabilities, including flaws affecting Citrix, Fortinet, and remote management platforms.
What makes this alarming is that many of these vulnerabilities already have available patches. Organizations often become victims not because the attack was extraordinarily sophisticated, but because basic security maintenance was neglected.
Inside an INC Ransomware Attack
Once attackers gain access, their workflow follows a familiar and efficient sequence.
Network discovery is typically conducted using standard administrative tools, ping commands, command-line utilities, Advanced IP Scanner, and network scanning software.
Credential harvesting follows shortly afterward. Attackers attempt to collect usernames, passwords, and authentication tokens that can help expand access throughout the environment.
Lateral movement then allows the attackers to spread across systems while remaining relatively unnoticed. Instead of deploying highly specialized malware, they frequently leverage legitimate operating system tools, a tactic commonly known as “living off the land.”
This approach reduces detection because many security products struggle to distinguish between legitimate administrative activity and malicious actions performed using the same tools.
Once valuable information is identified, attackers compress the data into archives and transfer it to attacker-controlled cloud infrastructure before launching encryption operations.
Rust Malware Gives INC Greater Flexibility
Although
Its ransomware payloads for Windows and Linux/ESXi environments have increasingly been rewritten using the Rust programming language.
Rust has become increasingly popular among cybercriminal developers for several reasons.
First, it supports cross-platform development, allowing malware creators to maintain a single codebase for multiple operating systems.
Second, Rust binaries are often more difficult for analysts to reverse engineer compared to malware written in older languages.
Third, the language enables efficient performance while maintaining relatively strong development flexibility.
While the ransomware itself does not introduce revolutionary capabilities, the move to Rust improves maintainability and operational effectiveness.
When Criminal Software Becomes a Commercial Product
Perhaps the strongest indication of
Reports indicate that portions of
This means the
Threat actors associated with ransomware operations such as Lynx and Sinobi are believed to have incorporated variants of INC malware into their own campaigns.
This mirrors legitimate software licensing models, except within a criminal marketplace.
When other ransomware operators are willing to purchase and reuse a malware framework, it signals confidence in its reliability and effectiveness.
Scalability Became INC’s Greatest Weapon
The most important factor behind
It is scalability.
Many ransomware groups become trapped by complexity. They require highly skilled operators, advanced infrastructure, and specialized knowledge that limits affiliate participation.
INC took the opposite approach.
By relying on proven techniques, widely available tools, and streamlined attack workflows, the group lowered barriers for affiliates.
This allows more participants to conduct attacks successfully with less training and fewer technical requirements.
The result is volume.
Instead of focusing on a handful of sophisticated operations, INC can support a much larger number of simultaneous campaigns across multiple sectors.
In cybercrime, volume often translates directly into revenue.
INC’s Position Among Today’s Most Dangerous Ransomware Operations
The modern ransomware ecosystem is crowded with aggressive actors competing for victims and affiliates.
Groups such as Akira Ransomware, Qilin, RansomHub, Play Ransomware, and Cl0p continue to dominate large portions of the threat landscape.
Yet INC has steadily climbed the rankings.
During the first quarter of 2026, the group reportedly entered the global top five ransomware operations for the first time, demonstrating that its operational model continues to attract affiliates despite fierce competition.
While analysts note fluctuations in activity levels throughout late 2025 and early 2026, the overall trajectory suggests a resilient and adaptable organization.
How Organizations Can Defend Themselves
The lessons from
Organizations should maintain offline and immutable backups following the 3-2-1 strategy. Three copies of data should exist across two different storage mediums, with one copy stored offsite.
Regular patch management remains essential because many successful ransomware attacks exploit vulnerabilities that already have available fixes.
Identity security should include multifactor authentication, privileged access controls, and credential monitoring.
Network segmentation can significantly reduce attacker movement after an initial compromise.
Security awareness training remains critical because phishing continues to serve as one of the most effective attack vectors.
Most importantly, organizations must assume that attackers will continue exploiting ordinary weaknesses rather than waiting for groundbreaking new attack techniques.
What Undercode Say:
The INC ransomware story reveals an uncomfortable truth about cybersecurity.
Many organizations continue searching for advanced threats while overlooking basic weaknesses.
Cybersecurity vendors often market artificial intelligence, behavioral analytics, and next-generation detection platforms.
Yet INC demonstrates that attackers still succeed using methods that have existed for over a decade.
The
It is a management failure story.
Unpatched servers remain exposed.
Weak passwords remain active.
Remote access services remain publicly accessible.
Employees continue clicking phishing emails.
Attackers simply capitalize on these recurring mistakes.
The healthcare focus is particularly strategic.
Hospitals operate under intense pressure.
Downtime affects patient care.
Executives must make decisions quickly.
This creates ideal conditions for extortion.
The migration to Rust is notable but not revolutionary.
Many analysts overemphasize malware programming languages.
The language itself does not make ransomware successful.
Operational discipline does.
INC appears to understand this better than many competitors.
Another important observation is affiliate economics.
Cybercrime increasingly resembles a franchise model.
Developers build tools.
Affiliates execute attacks.
Initial access brokers sell entry points.
Data brokers monetize stolen information.
Each participant specializes.
INC successfully inserted itself into this ecosystem.
The reported source code sales are equally significant.
When malware begins spreading between groups, attribution becomes harder.
Defenders may see different ransomware brands using remarkably similar code.
This blurs traditional threat intelligence tracking.
The broader lesson is alarming.
Defenders often expect future ransomware threats to be more advanced.
Reality suggests future ransomware may simply become more scalable.
Automation, affiliate expansion, and operational efficiency may matter more than technical innovation.
The organizations most at risk are not necessarily those facing elite hackers.
They are the organizations that continue neglecting cybersecurity fundamentals.
If INC has proven anything, it is that attackers do not need groundbreaking techniques.
They only need organizations that fail to execute the basics.
Deep Analysis
The technical workflow observed in INC campaigns aligns closely with modern enterprise attack chains.
Linux administrators should continuously monitor authentication logs:
sudo journalctl -u ssh sudo grep "Failed password" /var/log/auth.log
Identify suspicious network activity:
netstat -tulnp ss -tulnp
Detect unusual user accounts:
cat /etc/passwd lastlog
Audit privileged access:
sudo -l getent group sudo
Search for persistence mechanisms:
systemctl list-unit-files --state=enabled crontab -l
Check active processes:
ps aux --sort=-%cpu top
Monitor file integrity:
find / -perm -4000 2>/dev/null
Review firewall configuration:
iptables -L -n ufw status
Inspect network connections:
lsof -i
Verify patch status:
apt update && apt list --upgradable
Analyze failed login attempts:
lastb
Windows defenders should monitor:
Get-LocalUser Get-Process Get-NetTCPConnection Get-WinEvent
Enterprise defenders should regularly audit:
nmap -sV internal-subnet
Backup verification should include restoration testing rather than simple backup creation.
Immutable storage remains one of the strongest defenses against ransomware encryption.
Zero Trust architectures can reduce lateral movement opportunities.
Network segmentation significantly limits ransomware propagation.
Threat hunting for credential theft activity should be continuous rather than event-driven.
Security teams should prioritize reducing exposed services before investing in expensive security platforms.
The majority of INC attack paths begin with weaknesses that are entirely preventable.
✅ INC ransomware emerged in 2023 and rapidly expanded operations across multiple industries, according to threat intelligence reporting.
✅ Researchers report that INC primarily relies on established attack methods such as phishing, stolen credentials, and exploitation of known vulnerabilities rather than groundbreaking technical innovation.
✅ Healthcare organizations remain attractive ransomware targets because service disruption creates immediate operational pressure, making extortion campaigns more effective.
❌ There is no publicly verified evidence proving INC possesses the most advanced ransomware technology in the criminal ecosystem. Its success appears driven more by scalability and operational efficiency than technical superiority.
