How to Prevent Credential Theft: A Guide to Online Security

With a vast amount of personal data circulating on the internet, taking proactive measures to credential theft prevention is no longer optional to security. Cybercriminals constantly look for vulnerabilities, often targeting user credentials to gain unauthorised access to sensitive information. The consequences breaches: identity theft, financial loss, and reputational damage. 

A recent study underscores the urgency of this issue: the 2023 Verizon Data Breach Investigation Report reveals that a staggering 83 percent of breaches between November 2021 and October 2022 were attributed to external threats, with nearly half—49 percent—directly involving stolen user credentials. This alarming statistic serves as a wake-up call, highlighting the importance of vigilance for anyone navigating the online world. 

For every individual, safeguarding digital information is of utmost importance. With so much information readily available online, it is critical to understand the hazards and take precautions to protect our privacy. Malicious actors regularly exploit flaws and jeopardise important information by stealing credentials through credential theft. Such breaches can have far-reaching consequences, such as identity theft, money loss, and harm to one’s reputation.    

In this guide, we will explore the various tactics employed by cybercriminals to steal credentials and the effective strategies to safeguard your online security.  

Credential theft: A gateway to cybercrime 

Credential theft attacks involve the unauthorised acquisition of authentication credentials, typically usernames and passwords belonging to an organisation or individual. These stolen credentials are used to gain illegitimate access to sensitive data. Such attacks are often a preliminary step in more complex cyberattacks, allowing hackers to infiltrate systems, accounts, and networks undetected. Once inside, attackers can engage in malicious activities, including identity theft, data breaches, financial fraud, and espionage.  

They can even create new accounts, change passwords, and mess up business operations. For instance, by using stolen passwords, they might gain access to online services such as Dropbox, DocuSign, or Microsoft 365. This is especially easy if they target accounts that aren’t used much or have weak security.  

Credential theft tactics 

Credential theft is an evolving cybercrime. Hackers continuously refine their techniques to gain unauthorised access to user accounts. Let’s delve deeper into other prevalent methods employed by cybercriminals: 

Phishing: A classic yet effective method, phishing involves sending deceptive emails to trick recipients into clicking on malicious links or downloading attachments that lead to fake login pages. 

Social engineering: Social engineering is a psychological manipulation technique cybercriminals use to exploit human vulnerabilities and obtain sensitive information, particularly login credentials. Attackers create a sense of urgency by posing as trustworthy sources, like tech support or colleagues, and pressurize victims into sharing other valuable details.    

Brute force: A brute force attack involves an attacker systematically trying different username and password combinations across multiple accounts until they successfully breach one. The method also employs “dictionary attacks,” where attackers use common passwords and words from the dictionary to crack login passwords. 

Keylogger: Keyloggers are malicious software or hardware devices that record everything you type on a computer or device. When you enter your login information, the keylogger steals it and sends it to the attacker. Keyloggers can be secretly installed through infected emails, downloads, or if someone has access to your device. 

In addition to traditional methods, cybercriminals can purchase stolen passwords and login information from the dark web, a secret hidden corner of the internet inaccessible to standard search engines. Then there is Have I Been Pwned (HIBP), a widely utilised platform for cyber criminals and individuals to detect compromised credentials. Users can enter their email addresses or usernames to check if their information has been exposed to data breaches. If a user’s credentials are compromised, they will be flagged on HIBP. Individuals can utilise this resource to assess the security of their credentials and take necessary precautions, such as updating passwords and enabling multi-factor authentication. 

Taking a multi-layered approach 

Preventing credential theft requires a multifaceted approach that integrates cutting-edge technology, user awareness, and robust policies. Below are some effective strategies for combating credential theft. 

Enhance account security: Use two-factor authentication (2FA) or multi-factor authentication (MFA) instead of single-factor authentication (SFA). This reduces the risk of hacking, especially from phishing attacks. MFA methods include receiving a one-time code on your phone or email, scanning a digital badge, using a software token, or other similar techniques. 

Network traffic monitoring: Monitoring network traffic is essential for tracking, collecting, and analysing data to identify irregularities. This data-driven approach provides valuable insights into potential threat vectors and vulnerabilities, enhancing your network’s security. It can also detect credential theft attempts and raise alerts to defend against malicious content and network breaches. 

Empower employees: Organisations should invest in training programs to inform employees about the risks of credential theft tactics. By increasing awareness and getting regular updates on the latest threats and best practices, employees can better identify suspicious emails and avoid scams. 

Prioritising patch management: Software applications evolve continuously in response to emerging threats and technological advancements. Developers regularly release updates to enhance security measures, patch vulnerabilities, and introduce new features. These updates are crucial for maintaining the integrity and functionality of software systems. Patch management involves systematically keeping your software up to date with the latest security patches. This could fix vulnerabilities that might lead to account compromise.
