In a recent data breach incident, parts of Twitter’s source code were leaked online, posing significant risks to the company’s security and competitiveness. This incident highlights the importance of implementing robust security measures to safeguard intellectual property (IP), such as source code, and monitoring employees to prevent unauthorized access or theft.

What we know about the Twitter source code leak

Parts of Twitter’s source code were leaked on GitHub, an online collaboration platform for software developers, and remained public for several months before being taken down. According to arstechnica, the breach probably occurred on Jan 3, 2023– with GitHub closing access to the code on Mar 24, 2023.

Twitter has also asked the U.S. District Court for the Northern District of California to order GitHub to identify the person who shared the code and any other individuals who downloaded it. It is suspected that the person responsible for the leak left Twitter last year, around the time when Elon Musk bought the company and began a series of layoffs.

The exposure of Twitter’s source code presents significant security risks, as it could reveal vulnerabilities that hackers or other motivated parties could exploit to extract user data or take down the site. This incident underscores the need for companies to ensure the security of their intellectual property, especially given the lengthy amount of time sensitive data was exposed before action was taken by Twitter.

The risk of leaked source code

When source code is leaked, it exposes the company to several risks:

  1. Security vulnerabilities: Leaked code may reveal weaknesses in a company’s security measures, making it easier for hackers to exploit vulnerabilities and gain unauthorized access to user data or disrupt the platform’s operation. This can lead to financial losses, legal liability, and a loss of user trust.
  2. Loss of competitive advantage: Source code is often considered a company’s most valuable IP, as it contains the blueprint for its products and services. Leaking this code can provide competitors with insights into the company’s internal workings and potentially help them develop similar or superior products. In the case of Twitter, this could mean competing social media platforms gaining an edge by understanding Twitter’s algorithms and features.
  3. Damage to reputation and trust: Data breaches, especially those involving source code, can negatively impact a company’s reputation and erode the trust of its customers and partners. A damaged reputation can lead to customer churn, reduced investor confidence, and a decline in overall market value.

Recommendations for protecting source code

Instead of relying solely on platforms like GitHub to provide details on who posted the source code, companies like Twitter should have technology in place that monitors the movement of intellectual property, such as source code. By implementing such technology, companies can detect unauthorized access or movement of sensitive data, allowing them to take immediate action to mitigate potential risks.

Here are some recommendations on how security teams should approach the risk of intellectual property leaks:

Monitor employees for IP theft every day, not just during layoffs  

Companies should monitor their employees’ activities for signs of IP theft continuously, as disgruntled employees may be more likely to engage in such activities. By keeping a close watch on employee behavior, companies can identify potential threats and address them proactively.

Implement security technology that blocks employees from moving data in unauthorized ways

Companies should invest in advanced security technology that prevents employees from copying or transferring sensitive information, such as source code, without authorization. This could include tools that restrict access to specific data or monitor and log all data transfers.

Develop a strong security culture

Encourage employees to prioritize security and report any suspicious activities or vulnerabilities. A strong security culture can help prevent insider threats and ensure that employees understand the importance of protecting the company’s intellectual property.


The recent data breach at Twitter highlights the importance of protecting intellectual property and monitoring IP movement continuously. Companies should invest in advanced security technology, develop a strong security culture, and monitor employees for IP theft every day to safeguard their valuable intellectual property and minimize the risk of similar incidents in the future.
