Though we are recovering from the worst pandemic, cyber threats have shown no sign of downshifting, and cybercriminals are still not short of malicious and advanced ways to achieve their goals. The Global Threat Landscape Report indicates a drastic rise in sophisticated cyberattacks targeting digital infrastructures, organizations, and individuals in 2021. Threats can take different

Threat actors are increasingly banking on the technique of HTML smuggling in phishing campaigns as a means to gain initial access and deploy an array of threats, including banking malware, remote administration trojans (RATs), and ransomware payloads.
