What is Phishing?
Phishing is a fraudulent technique when a perpetrator poses as a reliable organisation or individual in an email or other correspondence. Phishing emails are often used by attackers to disseminate malicious links or files that allow them to get victims’ account numbers, login passwords, and other private information.
Because it is far simpler to fool someone into clicking on a malicious link in an email that seems to be authentic than it is to get past a computer’s security measures, deceptive phishing is a common kind of cybercrime. Gaining knowledge about phishing is essential to assisting people in identifying and averting it.
How is phishing carried out?
Phishing is a kind of cybersecurity and social engineering assault in which the attacker uses email and other electronic communication channels, such as social networks and Short Message Service (SMS) text messaging, to pretend to be someone else in order to get private information.
Phishers may get the victim’s personal information, employment history, hobbies, and activities by using public information sites like LinkedIn, Facebook, and Twitter. These tools are often used to find out details on possible victims, including names, work titles, and email addresses. Information may then be used by an attacker to create a convincing phishing email.
Data Science and Phishing:
By using sophisticated analytics and machine learning, data science strengthens the fight against phishing. Through careful examination of email content, sender details, and user behaviour, algorithms are able to recognise trends that may indicate phishing efforts. The use of natural language processing helps identify dubious links or misleading wording in emails. Sender reputation and website features are analysed to assist identify possibly fraudulent sources.
Responding quickly to new threats is made possible via real-time monitoring. Analysing user behaviour helps spot abnormalities like strange login locations or unexpected requests for private data. Data science models are able to adapt to changing tactics by continuously learning from new assaults, which gives them a strong defence against phishing in the digital world.

Methods of Phishing:
There are three primary phishing methods. However, there is one other method. The following provides an overview of these techniques:
i. Dragnet Method: In order to elicit a prompt response, spammed emails with forged corporate identity—such as trademarks, logos, and corporate names—are forwarded to a broad audience, such as members of a specific auction site or customers of a specific financial institution. The emails also contain links to websites or pop-up windows with correspondingly forged identification.
ii. The Rod-and-Reel technique: This approach focuses on potential victims who have already established contact. False information is directed at specific potential victims in order to coerce them into disclosing money and personal information.
iii. Lobsterpot Method: Phishers create websites that closely resemble reputable business websites in order to target a certain class of victims. reduced group of potential victims who are known ahead of time, but no victim reaction is elicited. It is sufficient for the victims to give personal information on the faked website believing it to be a reliable and authentic source.
iv. Gillnet phishing: In this technique, scammers insert harmful code into webpages and emails. One way they may abuse browser capability is by inserting malicious material into the pop-up window of another website. Internet users run the risk of unintentionally installing a Trojan horse on their computers only by opening a certain email or visiting a certain website. Malicious malware has the ability to alter user system settings, causing users who attempt to access authentic banking websites to be routed to a phishing page that seems similar.
Causes of the Growth in Phishing:
i. A tool like the “Universal man-in-the-middle phishing kit,” which builds complex phishing sites automatically, can be purchased for around $1000 on dark web marketplaces.
ii. Key-logging software is readily available and has the potential to secretly record key-stroking action and gather computer usernames and passwords.
iii. Consumers are tricked into filling out phoney surveys and giving phishers access to private account information by offering fake prizes.
iv. A few of the companies have lenient password policies. eBay, for instance, permitted combinations like james34231 for the user ID and james34 for the password. Google Mail also permits similar combinations.
v. Extremely high return on investment is another factor contributing to the rise in phishing. Setting up a phishing scheme to send 10,000,000 emails a month costs around $160. It makes roughly $125,000 even if just 0.001% of the email recipients reply.
Role of RBI:
The Reserve Bank of India (RBI) said at the monetary policy announcement on Friday that it will launch a specialised cloud facility for the financial industry in an effort to strengthen data security and counter the rise in cybercrime. The objective of the cloud facility is to improve company continuity, scalability, and privacy.
The RBI acknowledged that managing a “ever-increasing volume of data” was a need for banks and other financial institutions, adding that many banks had already begun using cloud services to do this.
“Banks and financial entities are maintaining an ever-increasing volume of data,” said RBI Governor in a statement. “A large number of them are making use of the cloud’s capabilities for this. For this reason, the Reserve Bank is constructing a cloud infrastructure for the Indian financial industry.”
Cases in India:
In the capital city, there were 72 reports of internet banking fraud in 2022, along with 91 reports of OTP fraud and 21 reports of ATM fraud. This emphasises how urgently strong defences against cyberthreats and the protection of private financial information are needed.
- Kingfisher Airline tickets were bought by fraudster who uses it to extract credit card data of more than 15,000 people
- NASSCOM employee sent email to thousands of people in NASSCOM’s name to extract banking information.
Conclusion:
In conclusion, the continuous fight against fraud in the banking and financial services industry has strong support from AI and Data Science. By using these technologies, organisations may improve their fraud detection skills and react more quickly to fraudulent activity, identify fraudulent activity more accurately, and adjust to the ever-changing strategies used by fraudsters. To keep ahead of new threats and maintain the greatest degree of security, Data Science Course in Mumbai must be updated on a regular basis.
