Sound-squatting is a squatting technique that exploits similarities in word pronunciation to trick users into accessing malicious resources. It is an understudied threat that has gained traction with the popularity of smart speakers and audio-only content,...

Recently, several researchers motivated the need to integrate Zero Trust (ZT) principles when designing and implementing authentication and authorization systems for IoT. An integrated Zero Trust IoT system comprises the network infrastructure (physical ...

Remote SIM provisioning (RSP) for consumer devices is the protocol specified by the GSM Association for downloading SIM profiles into a secure element in a mobile device. The process is commonly known as eSIM, and it is expected to replace removable SIM ...

Pre-trained language models (PLMs) aim to assist computers in various domains to provide natural and efficient language interaction and text processing capabilities. However, recent studies have shown that PLMs are highly vulnerable to malicious backdoor ...

We introduce a novel privacy-preserving biometric authentication scheme based on irises that allows a user to enroll once at a trusted biometric certification authority (BCA) and authenticate to online service providers (SPs) multiple times without ...

Malware attacks are posing a significant threat to national security, cooperate network, and public endpoint security. Identifying the Advanced Persistent Threat (APT) groups behind the attacks and grouping their activities into attack campaigns help ...
