During static code analysis SandBlast Mobile can identify such a behavior of malware that is trying to replicate itself to other devices and infect them too. Moreover, once unknown (zero-day) malware was identified, it will download the signature to the rest of the devices that run SandBlast Mobile in your organization, so even if the malware is capable of lateral movement and initiating such action all other devices will be protected.
