Guarding Against Credential Theft with Zero Trust

Credential theft is quickly becoming one of cybercriminals' most lucrative attack strategies. The convenience of saving credentials in browsers can expose users to significant risks, leading to costly breaches, disrupted operations, and damaged reputations. Numerous recent incidents highlight how attackers exploit stored credentials to gain unauthorized access to sensitive information, making it more important than ever for businesses to protect their digital entry points. Let's take a closer look at credential theft, why it's so profitable for attackers, and how Primary minimizes the growing risk.

The What, Why, and Who Of Credential Theft

Credential theft is when attackers gain unauthorized access to usernames, passwords, and session tokens, allowing them to impersonate legitimate users. One of the easiest methods involves accessing stored credentials within browsers, as employees often save them for convenience. But without advanced protections, these stored credentials can be easily exposed, allowing attackers to move laterally across networks, elevate privileges, and even initiate larger attacks, like ransomware.

Common techniques include:

• Credential Dumping: Attackers use tools to extract credentials saved in browsers, taking advantage of weaknesses in session management.
• Phishing and Social Engineering: Criminals manipulate victims into revealing their login information.
• Session Hijacking: Attackers intercept session tokens, effectively becoming the logged-in user.

Browser credential theft is often the first step for attackers to gain a foothold in an organization, from where they can launch more extensive attacks.

Credential theft is a low-risk, high-reward attack vector. Attackers use stolen credentials to access corporate accounts, granting them privileges to execute further attacks or steal sensitive information. A notable example includes hackers manipulating Google Chrome users into entering their passwords under a phishing scheme. Since credential theft often bypasses traditional defenses, many companies are vulnerable without specialized protections.

Behind many of these breaches are organized ransomware gangs and individual cybercriminals who use credentials to infiltrate networks and deploy malware. Groups targeting Google Chrome, for instance, found ways to exploit browser sessions, leading users to unknowingly provide access credentials.

Attackers leverage open-source tools, phishing, and advanced social engineering to trick users into entering sensitive information. Criminals prefer this strategy as it's effective, scalable, and difficult to detect, especially with traditional cybersecurity measures.

Credential theft is not only disruptive but can also be costly. The financial impact of breaches involving credentials is high, often surpassing other cyber incidents due to the access it grants to internal systems. For example, third-party credential compromises recently prompted another breach at ADT, impacting both operations and client trust.

How Primary Minimizes the Risk

To counter credential theft effectively, you need a solution built with security at its core. Primary offers several capabilities that significantly reduce the risk of credential theft and browser-based attacks.

1. Application Integrity: Primary ensures that applications only execute approved code, reducing the risk of malware injection and session hijacking. This stops many credential theft tactics before they begin.
2. Continuous Authentication: Unlike traditional browsers, Primary verifies each access request with continuous authentication, ensuring that any change in session or user behavior is flagged for further verification. This added layer of protection makes it harder for attackers to hijack sessions or steal credentials.
3. Built-in Threat Detection: Primary is equipped with advanced threat detection capabilities that identify and respond to unusual behavior in real time. Threats like credential dumping and session hijacking are flagged, isolating the compromised session before it can spread.
4. Enhanced User Controls: By allowing admins to set parameters around credential use and storage, Primary enables businesses to better control how users save and access passwords, reducing the risk of theft.

Combining these capabilities helps businesses proactively defend against credential theft and ensures that access controls are a source of strength rather than a vulnerability.
