+In the light of recent unsettling revelations regarding a backdoor discovered in the widely-used XZ Utils, 
+a compression tool used in Linux environments, including Red Hat and Debian systems, the cyber-security landscape has been abuzz with concern. 
+This discovery had a large potential impact on encrypted SSH connections, a backbone of secure communications in the tech world.
+
+At Appwrite, ensuring the security and trust of our developers and users is paramount. 
+We understand the concerns that arise from such vulnerabilities and their potential implications. 
+
+It's crucial for the Appwrite community to know that Appwrite's services **remain unaffected** by the XZ Utils backdoor. 
+This issue affected beta and test versions of Red Hat and Debian distributions, which Appwrite **does not use**.
+
+# What does this mean for self-hosting Appwrite?
+
+For our valued users who prefer the self-hosted route, leveraging Appwrite on affected operating systems (OS), 
+we understand your concerns. Here are our recommendations to ensure your self-hosted Appwrite instances remain secure:
+
+- Immediate Update/Removal: The first and foremost step is to check if you have the affect versions (`5.6.0`,` 5.6.1`) of the XZ Utils installed. If so, downgrade to a safe version or remove the utility altogether.
+- Enhanced Monitoring: Keep a keen eye on network traffic and system logs for any unusual activity.
+- Employ Firewalls: Employ stringent firewall rules to limit inbound and outbound connections to the bare minimum required for your operations. This reduces the attack surface significantly.
+- Regular System Audits: Conduct thorough audits of your systems to ensure no unauthorized modifications have been made to the OS or installed utilities.
+- Stay Informed: Follow updates from your OS's security advisory to apply security patches as soon as they are released.
+
+# Does this affect Appwrite Cloud developers?
+
+Appwrite Cloud users can rest assured that our cloud infrastructure is secure and unaffected by the XZ Utils backdoor.
+The Appwrite team has taken necessary measures to ensure that containers in our cloud environment do not have the affected versions of the XZ Utils installed.
+We also took further steps to restrict SSH access to our cloud infrastructure to reduce attack surfaces further.
+No actions are required from Appwrite Cloud developers at this time.
+
+In a world where cyber threats are evolving at an alarming pace, 
+the Appwrite team is committed to ensuring the security and reliability of Appwrite Cloud's infrastructure,
+so you can build applications with peace of mind.
+The team will continue to monitor the situation closely, take necessary actions to mitigate any potential risks,
+and communicate any updates transparently to the community.
