How Does Strandhogg Malware Work?
Strandhogg typically spreads through malicious applications that are downloaded from third-party app stores.
Once installed, the malware can run in the background and remain hidden from the user. When a legitimate application is launched, Strandhogg can exploit the Task Affinity vulnerability to insert itself into the application's task stack.
This allows Strandhogg to take control of the application and display its own interface over the top of the legitimate application's interface. This can make it difficult for the user to distinguish between the legitimate application and the malware.
