Inside One of the Largest International Cybercrime Operations to Date
In a groundbreaking international cybercrime crackdown, Interpol has successfully dismantled several high-impact infostealer malware operations as part of a massive coordinated effort called Operation Secure. Running from January to April 2025, the operation mobilized cybercrime units across 25 countries alongside major cybersecurity firms and infrastructure providers. The goal? To disrupt the growing global threat posed by malware designed to steal sensitive personal and corporate information.
This concerted global response reflects a shift in how law enforcement and private partners are tackling the evolving cyber threat landscape—by going on the offensive. With over 20,000 malicious domains neutralized, 41 servers seized, and 32 cybercriminals arrested, this initiative shows a bold new approach to fighting cybercrime at its roots.
Operation Secure: the Cyber Assault on Infostealers 🕵️♂️
Interpol’s Operation Secure targeted the global epidemic of infostealer malware, a stealthy and damaging type of software used to harvest confidential data from unsuspecting users. Law enforcement authorities from over 25 countries worked hand-in-hand with digital security companies, tearing through the complex web of malicious infrastructure supporting these cyber threats.
The heart of the campaign lay in Asia, with authorities disabling over 20,000 harmful IP addresses and domains, seizing 41 servers that acted as command-and-control (C2) centers. These servers facilitated the remote control of infected systems, allowing hackers to silently siphon off login credentials, financial details, and even cryptocurrency wallets.
One major hotspot turned out to be Hong Kong, where police uncovered 117 C2 servers spread across 90 internet service providers—a sign of just how embedded these networks had become. Authorities also retrieved a staggering 100GB of stolen data for forensic analysis.
A total of 32 individuals were arrested, including 18 in Vietnam, and 14 across Sri Lanka and Nauru. Most notably, Vietnamese police apprehended the alleged leader of a cybercrime ring, who was caught with stacks of cash, SIM cards, and business records linked to the illicit trade of stolen credentials.
But Operation Secure didn’t stop at arrests. During the mitigation phase, over 216,000 victims were identified and notified. Many were advised to reinforce their digital defenses and remain alert for suspicious activity. In total, nearly 70 malware variants were addressed in this massive crackdown.
With infostealer malware still ranked among the most dangerous threats today, tools like Bitdefender Ultimate Security are being recommended to the public. These offer protection not just from infostealers, but a broad spectrum of cyber threats, using AI, behavior monitoring, and real-time protection.
What Undercode Say: Behind the Operation and Cybercrime Landscape Analysis 🧠🔍
The Growing Complexity of Infostealers
Infostealer malware has evolved drastically in the last few years. These aren’t simple keyloggers anymore; today’s variants are modular, evasive, and built to scale, enabling threat actors to target hundreds of thousands of victims with ease. Operation Secure’s findings—such as 117 command servers in a single region—are a stark reminder of this trend.
Asia’s Role as a Malware Launchpad
While infostealers are a global issue, Asia has become a breeding ground for cybercrime infrastructure due to a mix of lax regulations, cheap server hosting, and growing underground markets. Hong Kong’s 90+ ISPs involved in malware distribution exemplify the region’s unwitting participation in enabling cybercriminals.
Criminals Professionalizing Operations
The apprehended leader in Vietnam highlights a broader trend: cybercrime operations are no longer run by hobbyists but by well-funded criminal enterprises, complete with business documentation, supply chains for stolen data, and even customer support on darknet marketplaces.
Victim Notification: A New Standard?
One standout element of Operation Secure is the direct notification of over 216,000 victims. This marks a possible turning point in law enforcement efforts—proactive outreach rather than silent investigation. It’s a model that could redefine how cybercrime response operates in the future.
Collaborative Enforcement Models Work
This operation proved that collaboration between law enforcement and cybersecurity firms can yield real, scalable results. It’s likely this model will be replicated in future campaigns targeting other forms of malware such as ransomware, phishing-as-a-service, or even AI-enhanced threats.
Role of AI in Modern Cybersecurity
With 70 malware strains being neutralized, traditional signature-based antivirus is no longer enough. AI-driven threat detection is becoming the frontline defense. Security suites now rely on behavior analysis and real-time monitoring to stay ahead of sophisticated malware.
✅ Fact Checker Results
Claim: Operation Secure dismantled major malware networks – ✅ Confirmed by Interpol with seizure stats and arrests.
Claim: Over 216,000 victims were notified – ✅ Interpol confirmed proactive victim notification efforts.
Claim: Infostealer malware is declining – ❌ Still considered one of the top cyber threats in 2025.
🔮 Prediction
The success of Operation Secure will set a new precedent in global cybercrime response. We predict a surge in collaborative takedowns targeting ransomware groups and phishing kits next. However, cybercriminals will adapt, potentially shifting operations to less-regulated regions or decentralizing their infrastructure further using blockchain-based control mechanisms. As threat actors evolve, AI-driven cybersecurity and international cooperation will be key pillars of defense.
