Official Statement on Trello Data Breach
To ascertain the veracity of the alleged Trello data breach, The Cyber Express Team reached out to officials for a statement.


In response to TCE, an Atlassian spokesperson acknowledged being aware of the threat actor’s claim regarding the Trello data breach. The Trello spokesperson told The Cyber Express, “We are aware of claims made by a threat actor about Trello user profile data.”

As the investigation unfolds, Atlassian emphasizes its commitment to safeguarding user data and pledges to take swift action if any breach is confirmed. Users are urged to remain vigilant and report any suspicious activity, while the company assures ongoing monitoring to uphold the security and privacy of the Trello platform.

“Our investigation is ongoing, though we have not found evidence to support that this data was gathered by unauthorized access. The security and privacy of our users’ data is our highest priority, and we continue to monitor Trello closely for any unusual activity,” told an Atlassian spokesperson.

This incident is not the first time Trello has faced security concerns. In 2020, reports emerged of a similar nature when Craig Jones, the Cybersecurity Operations Director at Sophos, uncovered personally identifiable information (PII) data exposed through public Trello boards.

Jones found that the default configuration of Trello boards is set to “private,” but many users unknowingly or intentionally switch these settings to “public.” Once made public, the contents of a user’s Trello board become accessible to anyone, including search engines like Google, which index public Trello boards, making the information easily discoverable.

Given the recurrent nature of Trello-related security issues, it raises questions about the platform’s ability to safeguard user data effectively. Users and organizations must remain vigilant and take proactive measures to enhance their data security posture.

What Should Be Done to Prevent Data Breaches?
In light of this alleged breach, it becomes imperative to address the broader issue of data security. Organizations and individuals alike should be vigilant and take proactive measures to safeguard their sensitive information. Here are some recommended steps to prevent and mitigate the impact of such data breaches:

Regular Security Audits: Conduct routine security audits to identify vulnerabilities in systems and networks. This proactive approach helps in detecting potential threats before they can be exploited.

Encryption of Sensitive Data: Employ robust encryption mechanisms to protect sensitive information both in transit and at rest. This ensures that even if data is compromised, it remains unreadable and unusable for unauthorized parties.

Multi-Factor Authentication (MFA): Implement MFA to add an extra layer of security beyond just passwords. This additional step makes it more challenging for unauthorized users to gain access to accounts and systems.

Employee Training: Educate employees about cybersecurity best practices, emphasizing the importance of strong passwords, recognizing phishing attempts, and reporting any suspicious activities promptly.

Prompt Software Updates: Keep all software, including security software, up-to-date to patch any vulnerabilities. Regular updates ensure that systems are fortified against known threats.

Incident Response Plan: Develop and regularly update an incident response plan to effectively handle and mitigate the impact of a data breach. This includes clear communication protocols and swift action to contain and resolve security incidents.

As this remains an ongoing situation, The Cyber Express Team is committed to keeping its readers informed of any developments related to the alleged Trello data breach. Stay tuned for updates on the Trello cyberattack as we continue to monitor the situation closely.
