Cloud-based messaging apps have revolutionized our connection, offering convenience, accessibility, and real-time communication. However, as with any technology, there are potential security risks that users and organizations should be aware of. While much focus is often placed on more traditional cyber threats, some less apparent dangers fly under the radar. We will explore five overlooked security risks associated with cloud-based messaging apps and provide insights into how to mitigate these threats.
- Inadequate data deletion
When you delete a message or conversation thread from a cloud-based messaging app, you might assume that the data is gone for good. However, this is only sometimes the case. Many apps do not permanently delete data immediately but instead mark it for deletion or move it to a temporary storage location.
Overlooked risk
Data retention and recovery – Some apps may retain deleted data for a period, which could be accessed by unauthorized individuals or used for purposes beyond your control. Deleted data may be recoverable using forensic tools, posing a risk to your privacy and security.
Mitigation
Secure data deletion – Look for apps offering secure data deletion practices, ensuring deleted messages are gone. End-to-end encryption also adds a layer of protection, making recovered data indecipherable. Check the app’s privacy policy to understand its data retention and deletion practices.
- Insecure syncing and storage
Cloud-based messaging apps sync your messages and media across multiple devices, offering seamless access to your conversations. However, this syncing process introduces security risks if not adequately secured.
Overlooked risk
Unsecured data transfer – As your messages and files sync between devices, they may be temporarily stored on intermediate servers or transferred over insecure connections, leaving them vulnerable to interception or tampering.
Inadequate local storage security – When messages and media are stored locally on each device, they could be accessed by unauthorized users if the device is lost or stolen or if local storage security measures are inadequate.
Mitigation
Secure syncing and storage – Choose apps that utilize end-to-end encryption for all data transfers, ensuring that only authorized devices can access your messages. Look for apps that offer local storage encryption to protect your data at rest on each device.
- Third-party app integrations
Cloud-based messaging apps often allow integrations with third-party apps, such as file-sharing services, AI assistants, or productivity tools. While these integrations enhance functionality, they introduce security risks.
Overlooked Risk
Expanded attack surface – Each third-party integration expands the potential attack surface for malicious actors. If the security of one integrated app is compromised, it could provide a gateway to access your messages or other sensitive data.
Mitigation
Careful integration management – Review the security practices of any third-party apps before enabling integrations. Understand how data is shared and stored, and consider the potential risks. Regularly review and revoke access for integrations you no longer need, reducing the chances of a breach. For a complete list of details, check my blog.
