Malware creates a mutex. Mutexes may be created for synchronization purposes (two or more processes/threads to share a resource).
Use in Malware
| Name | Date | Method | Description |
|---|---|---|---|
| Poison Ivy | 2005 | -- | Poison Ivy has a default process mutex, but can be altered at build time. [1] |
| Stuxnet | 2010 | -- | Malware creates global mutexes that signal rootkit installation has occurred successfully. [2] |
| Hupigon | 2013 | -- | Hupigon creates a mutex. [3] |
| Kovter | 2016 | -- | Kovter creates a mutex. [3] |
| Redhip | 2011 | -- | Redhip creates a mutex. [3] |
| Rombertik | 2015 | -- | Rombertik creates a mutex. [3] |
