SIMPLE CAT COMMAND EXPLOITABLE VIA MALICIOUS README

Security researchers have documented how a straightforward command—reading a text file with `cat`—can be exploited through malicious file contents. The vulnerability relies on embedded escape sequences and control characters that execute unintended actions when displayed in a terminal. The attack works because terminal emulators interpret certain sequences as commands rather than plain text. A crafted README file can trigger behaviors ranging from data exfiltration to command execution, depending on the terminal and its configuration. This represents a class of "mad bugs"—vulnerabilities hiding in plain sight within standard tools. The research was shared on Hacker News, generating significant discussion about terminal safety and the assumptions developers make about input handling. The finding underscores that security vulnerabilities aren't limited to complex software. Even minimal operations warrant scrutiny when user-controlled data intersects with system interpreters.
