Summary
Researchers have developed DSFDU, a detection method that identifies when attackers use unicode modifier letters (special invisible characters that change how other characters display) to hide malicious commands in living-off-the-land attacks (tactics where hackers exploit legitimate system tools already installed on a computer, rather than bringing their own malware). This technique allows defenders to catch obfuscated (disguised or hidden) commands that traditional security tools might miss.
