The -page- suggests a parameter name or delimiter, while each .. escapes one directory level. The final target is /etc/passwd (a Unix file listing user accounts).
As Alex examined the subject line more closely, they noticed that the sequence of characters seemed to resemble a URL. The "-page-" part stood out, followed by a series of "-2F-" codes, which looked suspiciously like URL-encoded characters. -page-....-2F-2F....-2F-2F....-2F-2Fetc-2Fpasswd
It looks like you’re trying to draft a blog post that includes a path traversal pattern ( ../../../../etc/passwd ), which is commonly associated with directory traversal attacks or security testing. The -page- suggests a parameter name or delimiter,
: This is an encoded version of ../ , which is the command to move "up" one level in a computer's directory structure. As Alex examined the subject line more closely,
If found in your logs, assume an attacker probed for file read vulnerabilities. Investigate the surrounding requests and the affected endpoint.
Path traversal attacks exploit vulnerabilities in the way a web application handles user-input paths. By manipulating these paths, an attacker can navigate the file system, potentially accessing files that are not intended to be exposed. The "/etc/passwd" file, often used in demonstrations, is a prime target because it is publicly readable and contains a list of all system accounts, along with information about their privileges.
