There’s a hoary old bit of Internet folklore, that in the mists of time when dinosaurs roamed the computer rooms, there existed a machine which could be upgraded by cutting a single wire.

In other words, the machine shipped with more power than you paid for, with some kind of a silicon handbrake to cripple the hardware until such time as you could afford to pay for an upgrade.

But that’s long ago and we do things differently now some people don’t learn from history.

Because apparently Tektronix sells equipment with built-in capabilities that costs money to enable, except if you can program an EEPROM. And not with some encrypted password or string, no, apparently plain text available straight off of Tektronix’ website will do the trick.

So after Hackaday linked to Oontz’ website, Tektronix got all butthurt and issued a DMCA takedown notice.

Notes to Tektronix:

1. Streisand Effect. I wouldn’t have written this post if you had not got all upset.

2. Wayback Machine. Jason saved it all for us. Including the original post.

3. Once the cat is out of the bag, it becomes trivial to replicate. Even if you DMCA the Wayback Machine, and me, and everyone else… you still lose. See Note 1.

So, learn from this and design better security next time.
