Karnataka Struggle as Polymorphic Malware Wreaks Havoc, ₹2,900 Crore Lost in 2024
Bengaluru: Despite Karnataka appointing 16 cyber technicians to combat cybercrime, fraudsters continue to outpace security measures by deploying polymorphic malware, an evolving virus that alters its code to evade detection. In 2024, only 1,248 out of 20,092 cybercrime cases were solved, with victims losing nearly Rs 2,900 crore.
Unlike traditional malware, polymorphic malware disguises itself by constantly changing its form, making it harder for antivirus programs to detect. Security systems that rely on recognizing fixed patterns struggle against this new threat, as the malware encrypts itself, modifies its code, and injects misleading data, allowing it to bypass detection and steal sensitive information.
Polymorphic Malware: A Growing Cyber Threat
Experts describe this malware as a “digital chameleon” that spreads through phishing emails, fake downloads, and malicious website links. Once inside a system, it activates keylogging tools to steal passwords, banking credentials, and personal data. Some variants even redirect users to fake banking websites to capture login details. The malware also spreads across networks, altering its structure each time, making removal nearly impossible.

Challenges in Cybercrime Detection
Karnataka, the first state to establish a cybercrime police station, plans to upgrade its Forensic Science Laboratory (FSL) with advanced tools to counter evolving threats. Since 2019, the state has trained 176 judicial officers, 984 police personnel, and 3,799 officials in cybercrime investigation. However, outdated security tools remain a major challenge. The state currently relies on signature-based cybersecurity systems, which work like police databases that can only detect known threats. However, polymorphic malware constantly rewrites itself, making these systems ineffective.
A senior Cybercrime, Economic Offences, and Narcotics (CEN) official highlighted that cybercriminals frequently change digital footprints, email addresses, and IPs to avoid detection. While some criminals make errors—such as reusing credentials—most adapt quickly, making investigations difficult.
Urgent Need for Advanced Security Measures
Security officials emphasize that combating cyber threats requires real-time monitoring, AI-driven security systems, and advanced forensic tools. Karnataka’s planned cybersecurity upgrades aim to strengthen digital defenses, but experts warn that as technology evolves, so do the tactics of cybercriminals.
Authorities urge citizens to stay vigilant against phishing scams, avoid downloading unknown files, and verify financial transactions to reduce cyber risks.
