Cybersecurity 101: Complete Guides to Cyber Threats

As digital banking and online financial transactions continue to grow in India, cyber threats targeting banks and individuals have also become a bigger danger to worry about.
The Indian banking sector has witnessed a sharp rise in cyberattacks, with thousands of incidents reported annually, leading to significant financial losses and data compromises.
“Cybercriminals employ a wide range of evolving tactics, including identity fraud using multiple mechanisms, mule accounts, and phishing attacks. These threats often involve fake mobile applications, deceptive websites, and fraudulent call center number listings designed to manipulate and mislead unsuspecting customers. Additionally, email phishing campaigns have always remained a threat, tricking individuals into revealing sensitive information,” Ankush Tiwari, Founder and CEO, pi-labs, told Firstpost.
We take a look at the most common types of cyberattacks targeting banks and individuals in India:
Phishing attacks: Phishing is one of the most prevalent forms of cyberattacks in India, targeting both banks and individuals.
These attacks often involve deceptive emails or websites that trick users into revealing sensitive information such as login credentials or financial details.
Malware attacks: Malware, including viruses and trojans, is frequently used to compromise banking systems and individual devices. In 2023, there were 1,185 reported incidents of virus/malware attacks on Indian banks.
Ransomware attacks: Ransomware has become a significant threat, with 78 per cent of Indian organisations experiencing a ransomware attack in 2021. In 80 per cent of these cases, the attacks resulted in data encryption.
Notable examples include the WannaCry attack, which affected over 200,000 computer systems in India, including banks.
Data breaches: Large-scale data breaches have exposed sensitive information of millions of customers. For instance, the Zivame breach affected around 1.5 million customers, compromising personal data such as names, email addresses, and phone numbers.
Network scanning and probing: In 2023, there were 12,330 incidents of network scanning and probing reported in the Indian banking sector, making it the most common type of cybersecurity incident that year.
Financial fraud: Cyber frauds targeting individuals, such as stock trading scams, have become increasingly common. In the first nine months of 2024, stock market trading scams alone resulted in losses of Rs. 4,636 crore.
With inputs from agencies
Phishing scams have become one of the most effective tools for cybercriminals, using deception and psychological manipulation to steal financial information from unsuspecting individuals.
These scams rely on tactics such as impersonation, urgency, and fraudulent communication to trick victims into revealing sensitive data like banking credentials, credit card details, and passwords.
Understanding how phishing works can help individuals stay vigilant and protect their financial assets.
One of the most common phishing tactics is impersonation, where scammers pose as legitimate entities such as banks, financial institutions, or well-known companies. By mimicking official emails, websites, or even customer service representatives, fraudsters create a false sense of trust, making victims more likely to comply with their requests.
Phishing attacks often create a sense of panic to pressure victims into acting without thinking critically. Scammers may claim that an account has been compromised, a payment is overdue, or immediate action is required to avoid legal consequences. The urgency forces victims to make rushed decisions, leading them to disclose personal or financial information.
Many phishing attempts come in the form of emails or messages that appear legitimate. These communications often contain official logos, proper formatting, and professional language, making them look authentic. They may ask recipients to verify their accounts, reset passwords, or provide financial details under the pretense of security checks or service updates.
A key component of phishing scams is the use of malicious links that direct victims to counterfeit websites designed to steal their data. These fake websites closely resemble legitimate banking or payment portals, tricking users into entering their login credentials. Once entered, the information is captured by attackers and used for fraudulent transactions or identity theft.
Beyond emails, scammers also use phone calls and text messages to deceive victims. In vishing attacks, fraudsters impersonate bank officials, government agencies, or even family members, requesting sensitive information or immediate money transfers. Smishing scams, on the other hand, involve text messages that urge recipients to click on malicious links, provide account credentials, or install malware on their devices.
Another common phishing tactic involves sending fake security alerts, claiming that suspicious activity has been detected on an account. Victims are then asked to verify their identity, unknowingly handing over personal information. Similarly, in workplace scams, attackers impersonate executives or colleagues, requesting urgent wire transfers or confidential financial details, often targeting employees in finance departments.
With advancements in artificial intelligence, cybercriminals are now using AI-enabled chatbots and voice generators to create highly convincing phishing attempts. These sophisticated scams can generate personalised emails, replicate human-like conversations, and even mimic the voices of trusted individuals, making it harder for victims to identify fraudulent activity.
Phishing scams exploit human emotions such as trust, fear, and curiosity. Many victims fall for these scams because they appear urgent, convincing, and seemingly come from trusted sources. With financial fraud on the rise, it is crucial to recognise these deceptive tactics and adopt proactive measures to stay protected.
As phishing scams become increasingly sophisticated, awareness and vigilance are key to protecting financial information. By understanding how these scams operate and taking preventive measures, individuals can reduce their risk of falling victim to cyber fraud.
In an era of increasing cyber threats, banks employ a range of security measures to safeguard customer data and financial transactions. From robust login credentials to advanced encryption methods, financial institutions implement multiple layers of security to prevent fraud and unauthorised access.
The first line of defence is the login process, which requires customers to enter unique credentials. Banks mandate strong passwords that include a mix of letters, numbers, and special characters. Many also set minimum password length requirements and restrict users from reusing their last few passwords.
To enhance security, banks rely on multifactor authentication (MFA), requiring more than one form of identity verification before granting access. This often includes something the user knows, such as a password or PIN, and something the user has, such as an ATM card or a smartphone for one-time passwords (OTP). Some banks also use biometric authentication, including fingerprint or facial recognition, for added protection.
Banks secure online transactions and sensitive information using encryption software, which converts data into unreadable code. Only authorised systems can decrypt and process this information, preventing unauthorised access.
Financial institutions monitor accounts in real time to detect unusual activity, such as large or suspicious transactions. Automated fraud detection programs analyse customer spending patterns and flag potential threats. If an anomaly is detected, banks may temporarily block transactions and notify the customer for verification.
Strict privacy policies ensure that customer data is handled with care and in compliance with federal and state regulations. Employees undergo rigorous training to prevent data breaches and unauthorised access to confidential information.
Beyond these core protections, banks implement other security protocols, including:
By implementing these security measures, banks strive to protect customer data from cyber threats and financial fraud, reinforcing trust in digital banking services.
Two-factor authentication (2FA) is a security system that requires users to provide two distinct forms of identification to access an account or system. In the context of online banking, 2FA adds an extra layer of protection beyond the traditional username and password combination.
The first factor in 2FA is typically something the user knows, such as a password or PIN. The second factor is usually something the user has, like a smartphone to receive a one-time passcode, or something the user use, such as a biometric characteristic like a fingerprint or facial recognition. This dual-layer approach significantly enhances security by making it much more difficult for unauthorised individuals to gain access to sensitive financial information.
The importance of 2FA in online banking cannot be overstated. As cyber threats continue to evolve and become more sophisticated, relying solely on passwords has become increasingly risky.
Passwords can be compromised through various means, including phishing attacks, social engineering, or brute-force attempts. By implementing 2FA, banks create an additional barrier that hackers must overcome, even if they manage to obtain a user's password.
2FA offers several key benefits for online banking security. It provides enhanced protection against unauthorised access, significantly reducing the risk of fraud and identity theft. It also helps mitigate the impact of phishing attacks, as attackers would need both the password and the second factor to gain entry.
This added security measure instills greater confidence in users, encouraging them to engage more freely with online banking services.
Moreover, 2FA helps banks comply with regulatory requirements set by authorities like the Reserve Bank of India, which mandates multi-factor authentication for certain types of transactions. This compliance is key for maintaining customer trust and ensuring the legal operation of digital banking services.
Open banking is transforming the financial industry by enabling greater transparency, innovation, and convenience.
By allowing third-party providers access to banking data through secure application programming interfaces (APIs), open banking facilitates seamless financial services, from budgeting apps to faster loan approvals.
However, as with any digital-first system, this interconnected ecosystem also introduces new cybersecurity risks that banks, financial technology companies, and consumers must navigate.
The fundamental concept of open banking relies on APIs to facilitate data sharing between banks and third-party service providers. While this enhances financial accessibility and competition, it also creates new attack vectors for cybercriminals. APIs, if not properly secured, can become entry points for unauthorised access, leading to potential data breaches and financial fraud.
“Open banking brings significant benefits to the financial ecosystem, but its digital-first nature also introduces new cybersecurity risks. Making APIs and data accessible to third parties increases vulnerabilities, including risks such as account takeovers, identity theft, and man-in-the-middle attacks. Additionally, ensuring third-party compliance and verification becomes more complex, especially with evolving data privacy regulations,” Ankush Tiwari, Founder and CEO of pi-labs, told Firstpost.
Account takeovers and identity theft: Open banking relies on user authentication mechanisms to grant access to third-party providers. Weak authentication or phishing attacks can lead to account takeovers, where cybercriminals gain unauthorised control over user accounts, enabling fraudulent transactions or identity theft.
Man-in-the-middle (MitM) attacks: Open banking transactions involve the exchange of sensitive financial data between multiple parties. If communication channels are not sufficiently encrypted, hackers can intercept these transactions, manipulating or stealing critical information.
API security vulnerabilities: APIs serve as the backbone of open banking, but poor implementation or misconfigurations can expose them to attacks such as API injections, denial-of-service (DoS) attacks, or unauthorised data access. Cybercriminals can exploit weak authentication controls to gain access to customer data or banking systems.
Third-party compliance risks: Banks and financial institutions must ensure that all third-party providers accessing their systems comply with data security regulations. However, maintaining oversight over multiple fintech partners can be complex, increasing the risk of data mishandling or non-compliance with evolving privacy laws such as the Personal Data Protection Bill in India or GDPR in Europe.
“Using AI in banking introduces new threat vectors, making it crucial for users to stay vigilant against emerging AI-driven fraud. For instance, live deepfake calls have successfully deceived many individuals, posing a significant risk to identity verification. In fact, face and video authentication systems are vulnerable to deepfake attacks.
As banks deploy more AI, new attack vectors arise to steal user data from AI agents. We have seen hackers able to access private data by conducting cyber attacks on AI agents.
To maintain security in an AI-driven digital landscape, users and cybersecurity measures must continuously evolve,” Ankush Tiwari, Founder and CEO, pi-labs, told Firstpost.
With the rapid advancements in artificial intelligence (AI), deepfakes have become a topic of global discussion. Initially gaining popularity for their use in entertainment and creative industries, these hyper-realistic fake videos and audio recordings are now posing significant risks.
As deepfake technology becomes more accessible, concerns are rising over how it could be exploited for malicious purposes, especially in the financial sector.
But what are deepfakes? And can they boost financial fraud?
The word "Deepfake" is a combination of "deep learning" and "fake". In common parlance, it refers to AI-generated media where a person's likeness or voice is convincingly replicated.
By analysing large datasets of images, videos, or audio samples, AI algorithms can replicate a person’s face, expressions, and voice with astonishing precision. These fabricated videos and audio clips are often so convincing that distinguishing them from authentic content is difficult without specialised tools.
While the technology has legitimate applications in movies, advertising, and education, it can be weaponised by fraudsters to carry out sophisticated financial scams.
Criminals can impersonate high-ranking executives, trick employees, and authorise unauthorised transactions.
The same technology can also be used to impersonate someone's close family member or friend. Imagine getting a distressed call from your spouse asking for quick money transfer to an account due to an emergency.
Deepfakes are also being used to manipulate stock prices by spreading false statements attributed to corporate leaders. This type of deception can lead to panic, affect investor decisions, and cause significant market fluctuations.
These are not one-off incidents. According to a report by Deloitte, Deepfake incidents in the fintech sector increased by 700 per cent in 2023.
Here are a few steps being taken to prevent deepfake frauds:
Using public Wi-Fi for financial transactions significantly increases the risk of cyberattacks on your bank accounts and e-wallets.
Here's why you should avoid using public Wi-Fi for such activities:

Man-in-the-middle attacks: Hackers can position themselves between you and the network, intercepting sensitive information like login credentials and financial data.
Malicious hotspots: Cybercriminals create fake Wi-Fi networks that mimic legitimate ones, tricking users into connecting and exposing their data.
Packet sniffing: Attackers can use special software to capture data packets transmitted over the network, potentially accessing your entire web activity.
When using public Wi-Fi for banking or e-wallet transactions, you expose yourself to:
To protect yourself, avoid using public Wi-Fi for any financial transactions. Instead, use secure, private networks or mobile data for sensitive activities. If you must use public Wi-Fi, employ a VPN to encrypt your connection and add an extra layer of security
Scammers can potentially access your bank account, online transactions, and e-wallet details through the darknet. Here's how:
The dark web poses significant risks, particularly in terms of data breaches, malware infections, and financial fraud.
When personal and financial data are breached, cybercriminals often sell this information on the dark web, leading to identity theft and fraud. Stolen details like credit card numbers and social security numbers can be used for illegal activities, resulting in significant financial and personal harm for victims.
Additionally, malware can be unknowingly installed from unsafe websites or infected downloads. Cybercriminals use it to track keystrokes, steal data, or access financial accounts, often without the victim's awareness.
To protect yourself from these threats, it is essential to enable two-factor authentication on all accounts, adding an extra layer of security against unauthorised access. Additionally, avoiding the sharing of sensitive information such as one-time passwords (OTPs) or card details with unverified sources can help prevent fraud. Regularly monitoring bank statements for any suspicious transactions is also crucial in detecting and responding to potential breaches quickly.
Using strong, unique passwords and refraining from saving payment details on unfamiliar or suspicious websites can further enhance security. Since the darknet serves as a hub for organised cybercriminal activities, maintaining vigilance and adopting robust cybersecurity practices are vital to safeguarding personal and financial information from potential threats.
Scammers are growing cleverer, and it is critical to be updated about their strategies.
Here are some frequent methods scammers and fraudsters are attempting to steal money from people:
