This blog delves into the top five cyber-attacks in India, exploring their intricacies, impact, and the lessons they impart for strengthening our digital defenses.
In August 2018, Pune-based Cosmos Cooperative Bank fell victim to one of the most sophisticated and coordinated cyber-attacks in Indian banking history. The heist resulted in a staggering loss of approximately ₹94 crore (around $13.5 million), shaking the confidence of financial institutions nationwide.
The attack commenced with the infiltration of the bank’s ATM server by injecting malware, allowing the cybercriminals to bypass security protocols and gain unauthorized access to the bank’s systems. They cloned thousands of Visa and RuPay debit cards and executed coordinated withdrawals across 28 countries, with over 12,000 transactions carried out. Simultaneously, a SWIFT transfer of approximately ₹13.5 crore was made to a Hong Kong-based bank account.
While the exact identities of the attackers remain unknown, the operation bore the hallmarks of an organized cybercrime syndicate, possibly with international links. The primary motive was financial gain, executed through meticulous planning and technological prowess.
Upon detection, Cosmos Bank swiftly disabled its servers and initiated an internal investigation. They collaborated with the Reserve Bank of India (RBI), Cyber Crime Cell, and other financial institutions to track and mitigate the damage. The Maharashtra Police’s Cyber Cell launched a comprehensive probe, leading to a few arrests domestically. International law enforcement agencies were also involved to track overseas transactions. Post-attack, Cosmos Bank overhauled its cybersecurity infrastructure, implementing advanced firewalls, real-time monitoring systems, and conducting regular security audits.
The incident underscored the importance of continuous and proactive monitoring of banking systems to detect anomalies promptly. Enhancing cybersecurity awareness among employees can act as a frontline defense against such breaches. Combating cybercrime in India requires coordinated efforts between domestic and international law enforcement agencies.
In July 2016, Union Bank of India faced a significant cyber-attack targeting its Society for Worldwide Interbank Financial Telecommunication (SWIFT) system. The attackers attempted to siphon off $171 million, marking it as one of the most audacious attempts in the Indian banking sector.
The breach commenced with a spear-phishing email sent to an unsuspecting bank employee. The email contained malware that, once activated, provided the attackers access to the bank’s internal systems. With this access, the hackers retrieved the necessary credentials to initiate unauthorized SWIFT transactions, transferring $171 million to accounts in Cambodia, Taiwan, Mauritius, and Australia.
The attack mirrored the infamous Bangladesh Bank heist, suggesting possible involvement of the same or similar hacking groups, likely motivated by substantial financial gain.
Union Bank’s internal security systems detected the anomaly shortly after the transaction was initiated. The bank coordinated with the receiving banks and international authorities, successfully blocking and recovering the entire amount before it could be withdrawn by the fraudsters. Post-incident, Union Bank reinforced its email security protocols, implemented stricter access controls for critical systems, and conducted extensive employee training on phishing awareness.
The attack highlighted email as a vulnerable entry point, emphasizing the need for robust email security solutions and employee vigilance. Prompt detection and swift action are critical in minimizing damage and recovering assets in cyber-attack scenarios. Implementing stringent access controls and multi-factor authentication can significantly reduce the risk of unauthorized system access.
Aadhaar, India’s unique identification system managed by the Unique Identification Authority of India (UIDAI), has been at the center of multiple alleged data leak controversies. In 2018, reports surfaced claiming that personal information of over 1.1 billion citizens was exposed, raising severe privacy and security concerns.
Investigations revealed that certain government and third-party websites inadvertently displayed Aadhaar details, including names, addresses, and other personal information. Journalistic investigations uncovered instances where access to Aadhaar data was purportedly being sold through WhatsApp groups and other online platforms for minimal amounts.
The leaks were primarily due to negligence and inadequate security measures rather than coordinated cyber-attacks. However, some instances involved malicious actors exploiting system vulnerabilities for financial gain and identity theft.
UIDAI consistently denied any breach of its central database, attributing the leaks to misuse by external agencies and assuring that biometric data remained secure. Investigations were launched against entities and individuals involved in unauthorized access and dissemination of Aadhaar information. To enhance security, UIDAI introduced measures such as the Virtual ID system, allowing users to use a temporary, revocable 16-digit number instead of the actual Aadhaar number for authentication purposes. In September 2018, the Supreme Court of India upheld the constitutional validity of Aadhaar but imposed restrictions on its usage, mandating stricter data protection and privacy safeguards.
The incidents underscored the critical importance of data privacy and the need for comprehensive data protection laws. Ensuring all entities handling sensitive data adhere to stringent security protocols is essential to prevent leaks. Educating citizens about safeguarding their personal information and understanding their rights regarding data privacy is vital.
In October 2019, the Kudankulam Nuclear Power Plant (KKNPP) in Tamil Nadu faced a cyber intrusion, sparking widespread alarm due to the critical nature of nuclear facilities.
The attackers deployed the DTrack malware, associated with the North Korea-linked Lazarus Group, infiltrating the plant’s administrative network. The initial breach likely occurred through targeted phishing emails, compromising employee credentials and gaining network access.
The Lazarus Group, known for high-profile cyber-attacks globally, was identified as the primary suspect. The motives were speculated to be espionage, aiming to extract sensitive information about India’s nuclear capabilities and infrastructure.
Initially, KKNPP authorities denied any breach. However, the Nuclear Power Corporation of India Limited (NPCIL) later confirmed the intrusion but clarified that the critical internal network was unaffected. Investigations concluded that the malware was confined to the administrative network, with no impact on plant operations or safety systems. Post-incident, NPCIL implemented stricter network segregation, enhanced monitoring systems, and conducted comprehensive cybersecurity audits across all nuclear facilities. The incident prompted the government to review and strengthen cybersecurity frameworks for critical infrastructure sectors nationwide.
The attack highlighted the vulnerability of critical infrastructure to cyber threats, necessitating specialized and robust security measures. Effective segregation between administrative and operational networks is crucial to contain potential breaches. Regular security assessments and real-time monitoring are essential to detect and respond to threats promptly.
In May 2017, popular food delivery and restaurant aggregator Zomato suffered a significant data breach, compromising the personal information of approximately 17 million users.
A hacker managed to exploit vulnerabilities in Zomato’s database, extracting user data including email addresses and hashed passwords. The stolen data was listed for sale on a popular dark web marketplace, raising concerns over potential misuse.
The breach was executed by an individual hacker using the alias “nclay”, purportedly to highlight the company’s security weaknesses. The hacker claimed no malicious intent and sought to ensure better data protection practices.
Zomato promptly acknowledged the breach, informing users and assuring that no payment information was compromised as it was stored separately with enhanced encryption. The company engaged directly with the hacker, who agreed to remove the listing from the dark web upon assurance that Zomato would launch a bug bounty program to improve security. Zomato reset all compromised passwords, implemented additional layers of security, and initiated a bug bounty program inviting ethical hackers to identify and report vulnerabilities. The company maintained transparent communication throughout the incident, updating users regularly and providing guidance on securing their accounts.
Regular security assessments and embracing ethical hacking through bug bounty programs can help identify and rectify vulnerabilities proactively. Ensuring robust encryption and secure storage of user data is imperative to minimize damage in case of breaches. Transparent and prompt communication with users during security incidents helps maintain trust and facilitates swift remedial actions.
