Obsidian plugin was abused to deploy a remote access trojan (cyber.netsecops.io)

Article summary

A social engineering campaign has been identified that uses the Obsidian note-taking application to deliver a remote access trojan (RAT) called PHANTOMPULSE. The campaign targets individuals in the financial and cryptocurrency sectors, and the attack relies on tricking the user into enabling a community plugin that executes code to deploy the RAT. The PHANTOMPULSE RAT demonstrates advanced capabilities, including using the Ethereum blockchain to dynamically resolve its command-and-control server address. The attack highlights the importance of being cautious when enabling third-party plugins and the need for improved security measures in applications like Obsidian.

What commenters say

• The Obsidian application itself is not vulnerable, but rather the users are being tricked into ignoring security warnings and enabling malicious plugins.
• The lack of sandboxing and access controls in Obsidian plugins poses a significant security risk, allowing malicious plugins to access sensitive files and systems.
• Some users argue that Obsidian is still a usable and secure application without community plugins, and that the risk of plugin-based attacks can be mitigated through careful user behavior.
• Others believe that the plugin system is inherently insecure and that users should be aware of the risks of installing software from untrustworthy developers, regardless of the application or platform.
• There is a need for improved security measures in applications like Obsidian, including better sandboxing and access controls for plugins, to prevent similar attacks in the future.
• The use of flatpak and snap packages can provide some level of security, but these systems are not foolproof and can still be vulnerable to certain types of attacks.
• Some commenters suggest that operating systems should provide better mechanisms for isolating and restricting the access of plugins and applications to user files and systems.
• The trade-off between security and usability is a significant concern, with some arguing that increased security measures could make plugins less useful or more difficult to use.
