The Army’s War Against Email Attachments

There’s one war where the Army has won every skirmish, every firefight, every battle, and every engagement.

That is the war against email attachments.

Luckily, they still allow soldiers to send JPGs of their junk to friends, family, and coworkers.

In accordance with NETCOM guidance 2004-11A,
AKO has begun stripping files with the following extensions:
.ace, .ad, .ade, .adp, .asp, .b64, .bas, .bat, .bhx, .ceo,
.ce0, .chm, .com, .cmd, .cpl, .crt,  .dbx, .dll, .dot, .eml, .exe,
.hlp, .hqx,  .hta, .inf, .ins, .js, .jse,  .lnk, .mdb, .mde, .mim, .msi,
.msp, .nch, .ocx,  .pi, .pif, .rar, .reg, .scr, .sct, .shb, .shs, .upx, .url,
.uue,  .uu, .vbe, .vbs, .vss, .vst, .vsw, .wmi, .ws, .wsc, .wsf,
.wsh, .xxe, and .zip.

Since this is an Army policy, AKO will not be able to grant exceptions.

Note: AKO stands for Army Knowledge Online.

  1. Hilarious!! They do this by file extension. That doesn’t sound very effective.

    For example,

    Attached, please find my z i p file. Please note that you will have to rename it from “.fred” to “. z i p” without the spaces, of course, prior to extracting it with winzip.

    That was easy.

  2. It actually is more effective then nothing. Almost all the extensions that they block are normally able to be executed in some form (either directly as an executable, or a script which can run other scripts and executables). If you rename the file with a “.e x e” extension, attempting to open it just by clicking on it will likely fail. It won’t prevent someone from sending you some type of malware via email, but it will take a conscious effort on the receivers part to rename the file to something that the system might recognize.

    You can’t fix stupid, but you can at least make inadvertent clicks have less of a consequence. And when you have a million people, even simple things that look silly to the educated world can have a big impact preventing things from spreading like wildfire.
