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.
An open redirect lets an attacker use your trusted domain to send victims anywhere — the ideal setup for phishing and OAuth token theft. Here's how to build redirects that can't be abused.
Buffer overflows write past the end of a memory buffer, corrupting adjacent data and often reaching code execution. Here is how they work and how to prevent them.
Privilege escalation is how a limited foothold becomes full control. This explainer covers vertical vs. horizontal paths across Linux, containers, and cloud IAM.
CSRF makes a logged-in user's browser perform actions they never intended — changing an email, moving money, granting access — using the victim's own session. Here's how it works and how to stop it.
A race condition is a timing flaw where two operations that should happen in order overlap instead — enabling double-spends, TOCTOU bypasses, and kernel exploits.
One unvalidated filename and `../../../etc/passwd` reads files you never meant to expose — or worse, executes them. Here's how path traversal works and how to build file access that can't be tricked.
A single badly written regular expression can freeze an entire service under a short, crafted input. This is ReDoS — and it has taken down Cloudflare and Stack Overflow. Here's how to avoid it.
Clickjacking tricks a user into clicking something different from what they see by layering an invisible frame over a decoy page. Here is how to block it.
Logs are supposed to be your source of truth during an incident. Log injection lets attackers forge entries, break parsers, and — in the worst cases — trigger code execution from a log line.
