Devices Most Vulnerable To Hacking Smart Devices Smart devices, such as smartphones, are lucrative targets for hackers.Android devices, in particular, have a more open-source and inconsistent software development process than Apple devices, which puts them at risk of data theft or corruption.Hackers can also hijack a router to carry out wider malicious acts such as distributed denial-of-service (DDoS) attacks, Domain Name System (DNS) spoofing, or cryptomining.Jailbroken Phones Jailbreaking a phone means removing restrictions imposed on its operating system to enable the user to install applications or other software not available through its official app store.Hackers typically gain access to a computer using a Remote Access Trojan (RAT) in rootkit malware, which allows them to not only spy on users but also read their messages, see their browsing activity, take screenshots, and hijack their webcam.
