It is correctly identified by eleven AV vendors as PlugX malware.


We would also like to thank Ryan Olson, Benjamin Small, Richar Wartell, and Chris Clark from Palo Alto networks in publishing the discovery.


Given the use of lure documents designed with social engineering in mind, it is likely that the attackers use phishing or spam to target users who are unaware of these documents' malicious nature.


There is also proof of concept (PoC) code available already.

For organizations, Trend Micro™ Mobile Security for Enterprise provides device, compliance and application management, data protection, and configuration provisioning, as well as protects devices from attacks that leverage vulnerabilities, preventing unauthorized access to apps, as well as detecting and blocking malware and fraudulent websites.


Although our security precautions are robust, security issues can still occur, which is why we created a comprehensive security response process to respond to incidents.


In these attacks, attackers utilized the Eternal Blue exploit and harvested credentials as they moved across the environment, and then used existing system tools to kill security services within machines to hide their presence.


These unique consistencies make it extremely improbable that two different people named these mutexes.


We close this list with patching because it is the most important thing you can do.

We have observed that some of the WatchGuard and Asus bots were never cleaned up because these routers still try to connect periodically to old C&Cs that were secured or taken offline.


We believe this was likely done to monitor the progress of the ransomware and maintain an additional foothold in compromised systems.

Cyclops Blink has been around since at least June 2019, and a considerable number of its C&C servers and bots are active for up to about three years.


After the encrypted payload is loaded, the loader injects a malicious DLL into rundll32.exe.


This allows the attack to succeed even if the user simply views the file in the preview pane – with no clicks on the document necessary – making the attack much more dangerous.


This moves it to the back of the inbox there the victim is unlikely to ever see it.


We assessed that a surveillance vendor packaged and sold these technologies.


Analysis of the phishing pages revealed that most of them would redirect to the original webmail servers, which they copied after the victims sent out their login credentials.
