What are Source Code Leaks? Detect & Prevent Source Code Exfiltration

What are Source Code Leaks?

Source code leaks refer to the process in which the source codes of proprietary applications are made available to unauthorized persons or the public domain for various reasons.

This might happen in several scenarios, including when information is leaked through public repositories, hacking attacks, internal threats, or when it is posted in version control systems.

Such access can leak the application’s essential features and graphical interfaces, security weaknesses, and other valuable and unique concepts that may lead to terrible events or the loss of perceived exclusive ideas when exposed to the wrong hands.

Such leakage poses considerable risks, including legal violation, threats to the application’s security, misuse of core source code, and loss of patent.

Impacts of a Source Code Leak

A source code leak is a significant and potentially devastating event for an organization. One of the most apparent effects is that cyber security threats have become more significant.

Depending on the nature of the code they access, hackers can dissect the software to find its weaknesses and utilize them to their advantage.

These can include unauthorized access, data theft, and full-on compromise of the system.

The occurrences can damage the organization’s image, cause customers to lose confidence in the firm, and lead to excessive fines, compensation, and possible legal actions against the firm.

In addition to security issues, there are losses related to leakage of source codes and theft of intellectual property, as well as a shift in the competitive advantage.

The leaked code allows competitors or malicious individuals to steal the software, reducing the organization’s market power and putting its competitive advantage at risk.

Since the stolen code allows the competitors to market similar products without bearing the initial creation costs, this theft of intellectual property leads to high revenue loss.

Furthermore, it causes business interruption, pushes back the delivery of products and services, and requires costly code rewriting and additional security measures to address the consequences of the leak.

What Are the Causes of Source Code Leaks?

Human Error

Among the key reasons that lead to source code leaks, the most significant portion is shed off, causing human errors. This means that developers and other workers may publish the repositories of codes to the external world without intent.

It can occur due to some misclick or improper configuration of Git hosting services such as GitHub, GitLab, or Bitbucket, as well as mistakenly setting the private repository to public.

Furthermore, there can be instances in which the access controls are not correctly implemented and are metered. As a result, some unwanted personnel may gain access to some key codes.

For instance, employees may continue to use weak passwords or not enable two-factor authentication. Thus, terrorists and hackers can penetrate the systems quickly. Also, the potential of including additional ‘troublesome’ stuff like API keys or passwords within the source code increases the risks.

Poor Security Practices

Another area where security consciousness is lacking and which leads to source code leaks is that of inadequate security practices.

Companies that do not obfuscate plain text, passwords, keys, or other information that can be easily decoded into repositories and configuration files make it easy for hackers to attack them.

Likewise, not regularly updating dependencies could open the code base to known exploits if tweaked by malicious parties.

Weaknesses also include insufficient security policies for the program and inadequate security awareness among developers, which results in no adherence to the best practices in implementing code security and, therefore, the possibility of leaks.

Insider Threats

Practically, insider threats are quite a danger in terms of source code protection. Some insiders using various shortcuts can knowingly leak the code to portray dissatisfaction with their employers.

Such people could act due to greed, revenge, or because of an ideology that they support, like in the case of a terrorist attack.

Other internal threats that are hard to identify and prevent without proper organizational monitoring and auditing mechanisms may prove tricky to detect. This risk can be managed by granting access on a need-to-access basis and following up periodically in defense of granting access.

Real-Time Examples of High-Profile Leaks and Their Consequences

Example 1: Microsoft’s Windows Source Code Leak (2020)

Arising from social engineering, in September 2020, Microsoft was involved in a significant source code leak whereby Windows XP and Windows Server 2003 source codes were leaked online.

Although these operating systems were outdated, the leak had extensive ramifications. First, it was a security problem since hackers could learn details of the code to identify specific weaknesses, including those that may remain unaddressed in other versions of Windows or other compiled applications still in use.

This situation also exposed Microsoft to criticism over its practices, especially regarding security, and an appeal for the firm to do more to protect its source code.

Also, the leak prejudiced the company, especially Microsoft, as people learned of loopholes in the company’s internal security measures.

Example 2: Nintendo’s Gigaleak (2020)

The year 2020 was not very good for Nintendo since it experienced something now referred to as the “Gigaleak” when tens of thousands of documents containing information about the company were leaked on the internet.

This involved source codes, design documents, prototypes, and many other documents and data that belong to many of the original Nintendo consoles and games. The consequences were multifaceted.

On the one hand, the leak benefited historians, fans, and developers because it granted an unprecedented view into Nintendo assets that had never been seen before.

It gave an idea of the company’s development processes and the design of its games, which were initially intended to be developed but were canceled for some reason.

Example 3: AMD Graphics Source Code Leak (2020)

In March 2020, several source codes about AMD graphical processing units, such as Graphics Core Next (GCN) and Navi GPUs, were leaked. The perpetrator said they had hacked the code from an insecure system/computer.

This leak brought with it some realistic results. First, it jeopardized vital information that, for competitors, can be leveraged to develop strategies that would put the company at a disadvantage.

Secondly, it has security implications as the source code can be reverse analyzed to figure out the flaws that hackers have designed.

AMD downplayed the event, arguing that the stolen files were not sensitive enough to harm AMD’s competitiveness and product security. However, it exposed the company to criticism regarding its security management.

How to Identify Source Code Leaks?

Preventing source code leakage is a big challenge that demands constant monitoring and a blend of automated and manual systems.

One of the basic approaches is utilizing automated monitoring systems that constantly monitor the web, searching for leaked code or its fragments.

They can be tailored to detect specific signatures or patterns in the code identifying a target company. Indeed, version control systems (VCS) such as Git can be configured to monitor and notify administrators of any suspicious actions, such as unauthorized access attempts or any modifications to code.

Logging and monitoring also significantly detect and analyze accesses and changes to source code repositories.

Also, security audits and getting penetration testing done frequently help in knowing the risks that can result in source code exposure.

Security audits are usually detailed assessments of the current state of access control, users’ rights, and the system’s overall security to determine possible missing links.

Penetration testing is the complete opposite; it threatens various aspects of a business to assess the reliability of protective systems. The issues of employee training and awareness are equally crucial as HR might contribute to security vulnerability.

Shining the light on phishing attacks, social engineering tricks, and proper code management by the staff decreases the susceptibility of inside leakage.

In this way, using all these strategies, organizations can develop strong protection against source code leakage and, thus, be confident in their software.

How to Prevent Source Code Leaks?

To address this problem, a multi-faceted approach stressing technological safeguards and measures, procedures, and personnel can be employed effectively to prevent any leakage of source codes.

Here are several key practices to implement:

Access Control and Management

Limit access to source code by applying rigid RBAC to guarantee that only the allowed individuals can use a particular code.

Minimize access based on the least privilege principle, whereby users are only allowed the level of access required to justify their work.

Also, the access control should be checked and revised regularly, including when the employees receive a new position, or leave the company. Use VCS such as Git, which has enhanced measures to manage access privileges.

Encryption and Secure Storage

Cryptography is also used to protect the applications when stored and transferred from one point to another.

Encrypt data at rest and secrets using tools like HashiCorp Vault or Azure Key Vault, and apply best practices for password management.

Evaluate the protection of the encryption keys, fit them properly, and avoid the risk of key exposure by replacing them frequently.

Two-factor Authentication (2FA)

Ensure the use of two-factor authentication on all systems and services to which you access the source code. 2FA ensures users go through a two-phase identification process to access a resource; the first is a password, and the second is a code sent to a device.

Automated Code Scanning and Monitoring

Regularly apply automated code scanning tools, including SonarQube, Checkmarx, or Kiuwan, to review your code for open flaws and security imperfections.

Implement endpoint monitoring to detect and report any activity that is out of the norm or indicates malicious activity, including attempts at unauthorized access or code alteration. They assist in identifying what might be wrong right from the design stage of the software.

Regular Security Audits and Penetration Testing

Security audits should be conducted on a fixed schedule to independently evaluate existing access controls, user permissions, and other aspects of organizational security.

Conduct vulnerability and penetration testing to check the possibilities of an emulator attack and to see how secure the current measures are. Any gaps or weaknesses seen during these assessments need to be addressed immediately.

Best Practices for Source Code Security

Automated Code Scanning

Kiuwan, SonarQube, and Checkmarx are some of the code and application scanning tools that can proactively identify vulnerabilities and security risks at a source code level.

These work as SAST and SCA tools and scan the source code for vulnerabilities at the early stages of development to minimize the risks of the application and its components becoming compromised.

Limit User Access

Apply a Role-Based Access Control security measure in your source code so only authorized can alter or expose codes.

One of its advantages is that it allows you to set strict regulations and limitations for users and specify which code parts should be accessible to them, thereby preventing many security problems and keeping the information safe.

Two-Factor Authentication (2FA)

Find ways to enforce measures such as two-factor authentication in your source code repositories to reduce vulnerability.

With the help of 2FA, users must present two types of identity, like the password and a one-time verification code received through the mobile application, to access the codebase.

This saves on the fact that it helps prevent unauthorized access and ensures the security of the information that may be stored in the code.

Clear Source Code Security Policies

Develop formal and specific source code security rules for programmers to know how to write secure code. The guidelines should include policies for conducting code reviews, handling vulnerabilities, and policies regarding using third-party libraries.

Thus, by defining the security policies, you can ensure that everyone on the development team adheres to the standards and that the system is secure enough for use.

Verify Copyright

As a result, you need to ensure proper verification and documentation of the copyright for your source code so that nobody can misuse your intellectual property.

The ownership and licensing terms should be stated to ensure that unauthorized access or circulation of your code is curbed.

Application of version control systems like Git or Perforce helps track the changes made on code contribution and keeps the full history of copyright ownership record.
