In today's digital age, social engineering and data theft have become increasingly common and pose a serious threat to individuals and businesses alike. Social engineering refers to the use of psychological manipulation tactics to deceive individuals into divulging sensitive information or performing actions that may compromise their security. This can range from phishing emails and phone scams to impersonation and pretexting. Unfortunately, successful social engineering attacks often lead to data theft, which can have severe consequences for victims. Stolen data may include personal information, financial data, and intellectual property, among others. This can result in identity theft, financial loss, and reputational damage.
In this blog post, we will explore the topic of social engineering and data theft in-depth, starting with an overview of social engineering tactics and how they can lead to data theft. We will also examine real-life examples of social engineering attacks and their impact, as well as provide best practices and strategies for prevention and protection. By the end of this post, readers will have a better understanding of the risks posed by social engineering and data theft and how to mitigate them.
What is Social Engineering?
More often than not, modern computer systems and networks have sophisticated cybersecurity measures. This makes it harder for hackers to steal data from these systems. Hence, they turn to the weakest link in the entire computer network: humans. Regular employees working in crucial data security facilities like server rooms can be manipulated into giving critical information, even passwords, and credentials. This is why knowledge about social engineering is important. Social engineering is the use of psychological manipulation tactics to deceive individuals or organisations into divulging sensitive information or performing actions that may compromise the data security of the organisation. Social engineers use a variety of tactics to trick their victims, including phishing, pretexting, baiting, and tailgating, among others.
There have been numerous successful social engineering attacks in recent years, including the 2013 Target data breach, where hackers gained access to over 40 million credit and debit card numbers by stealing login credentials through a phishing email. Another example is the 2017 WannaCry ransomware attack, where attackers used a phishing email to distribute malware that encrypted computer files and demanded payment in exchange for the decryption key. Here are some common social engineering tactics that attackers may use to trick their victims according to Copado.
1. Phishing
This is one of the most popular methods used by cybercriminals to steal data through social engineering. An attacker sends an email that appears to be from a well-known bank, asking the recipient to click on a link and enter their login credentials. The link takes the victim to a fake website that looks like the bank's site but is actually controlled by the attacker. In India, the famed UPI payments are misused by cybercriminals to lure customers into sending money by clicking short links.
2. Baiting
An attacker leaves a USB drive containing malware in a public place where it is likely to be found by someone. The USB drive is labelled "Employee Salaries" or something else that is enticing to the victim, who then inserts it into their device, allowing the attacker to gain access to their computer. Most companies and organisations have banned employees from inserting external USB drives into their work PCs. Several companies have non-functional USB ports to avoid this type of cyberattack. However, with remote working, this attack has become resurgent in recent times.
3. Pretexting
An attacker calls an employee at a company and pretends to be from the IT department, asking for their login credentials to fix a technical issue. The attacker gains the victim's trust by using insider jargon and sounding authoritative. These cybercriminals convince unsuspecting individuals by introducing themselves as bank employees and mislead them into sending money or giving passwords or PINs.
4. Scareware
An attacker sends a pop-up message to a victim's computer that claims to have detected a virus and urges the victim to download a fake antivirus program or pay a fee to remove the virus.
5. Tailgating
An attacker follows an employee into a secure area, pretending to be a visitor or delivery person, and gains access to restricted areas or information. Data server rooms and restricted areas in organisations are the primary targets of this cybercrime.
6. Watering Hole Attacks
An attacker infects a website that a target is known to frequent with malware, like a popular news site or social media platform. When the target visits the infected site, their device becomes infected with the malware, allowing the attacker to gain access to their information or device. Contrary to popular opinion, any device can get infected just by visiting a website, even if the victim does not download any files from the site.

How does Social Engineering lead to Data Theft?
Social engineering can lead to data theft by exploiting human behaviour and trust to gain access to sensitive information. Social engineers may use a variety of tactics to accomplish this, including phishing, pretexting, baiting, and tailgating, as discussed earlier. Once social engineers have gained access to sensitive information, they can use it for a variety of purposes, including identity theft, financial fraud, or accessing confidential data. Types of data that can be stolen through social engineering include login credentials, credit card numbers, social security numbers, email addresses, and other personal information. In addition to personal data, social engineering can also lead to the theft of intellectual property and trade secrets. This can include confidential business plans, financial data, and other proprietary information. The attackers can replicate these trade secrets to set up other businesses to compete with the original company and undermine their business by offering cheaper alternatives.
Real-Life Examples of Social Engineering Leading to Data Theft
There have been several high-profile cases of social engineering leading to data theft in recent years, including the Equifax breach and the Target hack. In 2017, Equifax, one of the largest credit reporting agencies in the United States, announced that it had suffered a data breach that exposed the personal information of approximately 143 million individuals (Source: Wikipedia). The breach was the result of a vulnerability in a web application, which was exploited by attackers to gain access to sensitive data. The attackers were able to steal names, social security numbers, birth dates, and other sensitive information. This breach is considered one of the most significant data breaches in history and had severe consequences for those affected, including identity theft and financial fraud.
In 2013, Target, a major US retailer, suffered a data breach that exposed the credit and debit card information of over 40 million customers. The breach was the result of a phishing email that was sent to an employee of a third-party vendor that had access to Target's network. The employee clicked on a link in the email, which installed malware on the vendor's system. The attackers were then able to use the compromised vendor credentials to gain access to Target's network and steal customer data. The breach resulted in significant financial losses for Target and had a lasting impact on customer trust (Source: Red River). Other notable examples of social engineering attacks leading to data theft include the 2017 WannaCry ransomware attack, which exploited a vulnerability in the Windows operating system to encrypt computer files and demand payment in exchange for the decryption key, and the 2014 JPMorgan Chase data breach, which exposed the personal information of over 83 million customers.

Prevention and Protection against Social Engineering and Data Theft
Prevention and protection against social engineering and data theft require a combination of best practices, tools, and strategies. Here are some ways to protect yourself and your organisation.
1. Educate Yourself and Your Team.
One of the most fundamental steps in preventing social engineering attacks is to educate yourself and your team on the tactics used by attackers. This includes regular training on how to recognise and avoid phishing emails, social engineering tactics, and other threats. Spreading awareness about the different types of cybercrimes, scams, and tactics will keep everyone in the loop. This helps them identify social engineering attempts and react quickly to avoid any loss.
2. Use Strong Passwords and Multi-Factor Authentication.
Strong passwords and multi-factor authentication will protect your data from unauthorised access. Make sure to use unique passwords for each account and enable multi-factor authentication wherever possible. While it is hard to remember every password for every other website, you can minimise the hurdles by using unique phrases or by using a password manager. Having multi-factor authentication will also help protect your online accounts and devices from unauthorised access.
3. Keep your Software Up-To-Date.
When vulnerabilities in software are found and patched, every user must update the software at the earliest possible time. However, this does not happen often. People neglect software updates and opening up the possibility for hackers to exploit known vulnerabilities. Moreover, the software patch often contains details about the vulnerability and the fix. This inevitably helps cybercriminals exploit the vulnerability. Regularly updating software can help protect against these vulnerabilities. Make sure to keep your operating system, web browsers, and other software up-to-date. A well-informed team should not postpone suggesting updates indefinitely. Even a single computer or device running outdated software will only increase the chances of a data breach and compromise the entire network of an organisation.
4. Implement Security Tools.
Use security tools such as firewalls, antivirus software, and intrusion detection systems to monitor and protect against attacks. While this must be standard practice for all digital users, having several security systems can also slow down the device and keep it from achieving peak performance. However, this must not be an excuse to disable these security protocols or tools.
5. Limit Access to Sensitive Information
Often cybersecurity risks are compounded by several people unnecessarily having credentials for sensitive information. The more people have access to sensitive information, the more it is vulnerable to social engineering tactics. Limit access to sensitive information only to those who need it and implement access controls to prevent unauthorised access. Moreover, keeping logs on every piece of information like login ID, the device used, access location, IP address, time spent on the database, etc. will help in cybersecurity forensics if the database gets hacked. With the logs, it will be easier to identify the entry point of an attack, which will help in identifying further information about the attack and the possibility of data recovery.
6. Be Cautious with Emails and Links.
Be cautious when opening emails and clicking on links, especially from unknown sources. Look for signs of phishing emails, like suspicious links or requests for personal information.
7. Monitor Accounts and Credit Reports.
Regularly monitor your accounts and credit reports for any suspicious activity or unauthorised access. In this way, you can easily identify unauthorised money transfers and take the necessary steps to avoid them in the future.
