Message | POLICY FTP 'RETR 1MB' possible warez site |
Summary | An attempt to retrieve a file named "1mb" was detected on your ftp server.
|
Impact | Possible abuse ftp behavior by hordes of warez sites, and the existance of (potentially) illegal files/software on your ftp server.
|
Detailed Information | Warez sites have been known to name "warez" files by their size. Large files are split into smaller, more manageable chunks, and allow warez sites to store large files on ftp sites in a semi-organized manner. Once these files are uploaded, it is common practice for other warez users to attempt to retrieve them.

Affected Systems | |
Attack Scenarios | As part of an attempt to store elite warez on your ftp server, an attacker named his/her file "1mb" to indicate it's size. This file is likely part of an archive that represents a larger, most likely illegal copy of media.
|
Ease of Attack | If your ftp server allows write access (presumeably, anonymous), this is trivial. Furthermore, if your ftp server allows anonymously uploaded files to be downloaded, retrieval of these files simply requires knowing where they are located.
|
Corrective Action | Inspect your ftp server for a file named 1mb. If it exists, determine if the file is legitimate, or if it was (yet another) case of a warez site abusing ftp. Furthermore, evaluate your need for ftp read/write access.
