Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Zero width and other non printing characters can hide an encoded payload inside text that looks blank. Learn how it works and how to scan your own files for it.
An SVG looks like an image but is XML that can carry script. Learn how attackers use that to deliver payloads and what behavior to watch.
Dead code and NOP padding bury what a program really does. Learn how junk code differs from binary padding and why behavior based detection still works.
ZIP, 7z, gzip and self extracting archives hide payloads, and joined archives can fool some readers. Here is what MITRE describes and how to inspect archives safely.
Code that rewrites itself on every run breaks signatures by design. Learn why behavior based detection is the answer and what MITRE says to watch.
Base64, hardcoded keys, password protected documents and self extracting archives hide a payload until the moment it runs. See what to log and which controls help.
A Windows shortcut can hide a download address in its icon field. Learn how that works and how to stop a harmless looking .lnk from fetching a payload.
Payloads and stolen data can sit in the Registry, WMI, event logs or shared memory instead of files. Learn where to look and how to audit those places.
Carets, quotes, encoding and path tricks can make a command unreadable to filters while it still runs. Here is what to log, what to flag and which Windows controls help.
