Understanding credential harvesting
Credential harvesting is a technique used by cybercriminals to collect user credentials like IDs, email addresses, and passwords in bulk, often leading to a credential harvesting attack. Implementing robust cybersecurity protocols can help mitigate the risks associated with credential harvesting.
These harvested credentials are gold mines for hackers, allowing them to:
- Gain access to systems
- Gather sensitive data
- Sell or share credentials on the dark web
- Conduct more complex attacks
Real user credentials are particularly valuable because they enable attackers to impersonate account owners, bypassing many security measures designed to detect unauthorized privileged access.
The methods used to harvest credentials are varied and often involve social engineering tactics that manipulate individuals into revealing confidential information. The challenge for security defenses is that these attacks can be incredibly difficult to detect, as the attacker often appears to be a legitimate user and may attempt to steal credentials or use stolen login credentials.
Additionally, attackers exploit weaknesses in online environments, such as unsecured networks, to facilitate credential harvesting.
How credential harvesting works
Credential harvesting is a covert method where attackers collect access credentials using tactics like phishing and keystroke logging. Phishing is particularly effective, involving deceptive emails that trick recipients into providing their login credentials. These emails often contain links to fake websites that mimic legitimate ones, fooling users into entering their credentials. Newer methods even use QR codes, also known as QR phishing or quishing, leading to malicious websites, adding another layer of deception.
Attackers employ a variety of cyberattack vectors, including malicious attachments and stealth access, to gather credentials. Highly targeted phishing campaigns can exploit specific individuals within an organization, making these attacks more effective. Once a victim responds, threat actors may prioritize and retarget them for further attacks.
Adhering to strict cybersecurity protocols can help organizations detect and prevent these covert methods.
Credential theft can also occur through fake access points and unsecured traffic interception, making public Wi-Fi networks a common target. Credential harvesters record any information users enter during the login process, making them particularly intrusive. Whether through phishing, malicious websites, or other exploits, the end goal is always the same: to harvest as many credentials as possible. This covert nature makes it challenging to detect and prevent credential harvesting attacks.
Common techniques used in credential harvesting attacks
Phishing attacks remain the most prevalent technique used to deceive users into revealing their login details. As mentioned, cybercriminals often set up fake websites that mimic legitimate ones to capture user credentials. These phishing attempts are not limited to emails; attackers may also use instant messaging platforms to deliver phishing links to potential victims. The sophistication of these tactics can easily fool even the most vigilant users.
Keystroke logging and keyloggers present another common tactic, involving software that records every keystroke made by a user. This can be achieved through malware that logs keystrokes on infected devices, allowing attackers to steal passwords and other sensitive information. Public Wi-Fi networks are also frequently exploited for credential harvesting, as attackers can set up fake access points or intercept unsecured traffic.
Man-in-the-middle (MITM) attacks enable cybercriminals to intercept communications between two parties, often to extract login credentials without detection. Social engineering techniques are also employed to manipulate victims into revealing sensitive information.
These diverse methods illustrate the wide range of tactics used in credential harvesting attacks, making it essential to be vigilant and proactive in preventing them.
The impact of credential harvesting on organizations
The repercussions of successful credential harvesting attacks can be severe, leading to data theft and long-term compromise of networks. Data breaches resulting from credential harvesting can impact sensitive information and significantly hamper organizational trust. Over the past decade, 31% of data breaches involved stolen credentials, underscoring the widespread nature of this threat. Organizations can also experience a stock price decrease of around 3.3% and other significant financial consequences following a data breach, highlighting the financial impact.
Furthermore, fines for data breaches under regulations like GDPR can reach up to 4% of a company’s annual global revenue, adding another layer of financial risk. Credential harvesting can lead to significant operational disruptions, particularly in critical infrastructure sectors like energy and healthcare.
In summary, cybercriminals exploit harvested credentials for financial fraud and unauthorized access to sensitive data, posing a significant risk to organizations.
Why credential harvesting is increasing
Several factors contribute to the current rise of credential harvesting attacks. Many individuals use the same credentials across different systems and accounts, which raises the risk of credential theft. This common and risky practice of password reuse allows hackers to infiltrate multiple organizations easily.
In recent years, credentials have overtaken payment card data as the most commonly exfiltrated data in breaches. Single sign-on (SSO) systems, which store and manage numerous user credentials, can create vulnerabilities if not properly secured.
To safeguard their passwords, individuals are encouraged to use reputable password manager tools to minimize risks.
Top strategies to prevent credential harvesting attacks
A multi-layered security approach is crucial as it helps in defending against credential harvesting attacks. This involves not only technical defenses but also enhancing employee awareness and updating systems regularly. Implementing comprehensive cybersecurity protocols is a fundamental strategy to prevent credential harvesting attacks. Two critical strategies to prevent credential theft are email security protections and employee awareness training. Furthermore, organizations must assess, update, and patch systems regularly to protect against these attacks.
CISOs should create a tailored security framework and enhance defenses proactively before an incident occurs. Strengthening security defenses at the corporate level is crucial for defending against credential harvesting. This framework should be regularly reviewed and adjusted for maximum effectiveness.
Conducting a comprehensive email security assessment is an important first step in developing a robust strategy against credential harvesting. See below for additional security measures.
Implement multi-factor authentication (MFA)
Multi-factor authentication (MFA) requires two or more pieces of evidence for identity verification, significantly raising the barrier to entry for attackers. Implementing MFA is a recommended best practice to limit the effectiveness of credential harvesting. Even if a password is compromised, MFA can prevent unauthorized access.
By requiring multiple forms of verification, MFA can significantly reduce the risk of unauthorized access, making it a crucial tool in the fight against credential harvesting attacks.
Conduct regular security awareness training
Conducting regular security awareness training and simulations for employees on an ongoing basis can prepare them for recognizing and reporting credential harvesting attacks. Engaging employees through simulations can improve their ability to identify phishing attempts and other social engineering tactics.
By fostering a culture of vigilance and awareness, organizations can mitigate the risks posed by credential harvesting attacks and build a more resilient security posture.
Utilize Identity and Access Management (IAM) solutions
IAM solutions allow for the enforcement of role-based access controls to limit exposure to credential theft. These solutions are essential for managing user access and monitoring credential usage effectively. By restricting user access to only necessary resources, IAM solutions can significantly reduce the risk of credential theft.
Implementing IAM solutions also ensures that only legitimate users can access protected systems, further enhancing the organization’s security posture.
Real-time monitoring and threat intelligence
Utilizing threat intelligence can enhance awareness and understanding of credential harvesting tactics. Threat intelligence provides insights into emerging attack strategies, helping organizations adapt their defenses against credential theft. Continuous vigilance through real-time monitoring is crucial for identifying potential security breaches involving stolen credentials.
Integrating cybersecurity protocols with real-time monitoring can enhance the detection and prevention of credential harvesting.
Leveraging advanced security technologies and integrating threat intelligence feeds with real-time monitoring allows organizations to preemptively defend against credential misuse and respond swiftly to incidents.
