Alarm System Defeated By $2 Wireless Dongle, Nobody Surprised
The item in question is the SimpliSafe alarm system, a fully wireless, install-it-yourself system available online and from various big-box retailers. We’ve covered the system’s deeply flawed security model before, whereby SDRs can be used to execute a low-effort replay attack. As simple as that exploit is, it looks positively elegant next to [LockPickingLawyer]’s brute-force attack, which uses a $2 RF remote as a jammer for the 433-MHz wireless signal between sensors and the base unit.
With the remote in close proximity to the system, he demonstrates how easy it would be to open a door or window and enter a property guarded by SimpliSafe without leaving a trace. Yes, a little remote probably won’t jam the system from a distance, but a cheap programmable dual-band transceiver like those offered by Baofeng would certainly do the trick. Not being a licensed amateur operator, [LockPickingLawyer] didn’t test this, but we doubt thieves would have the respect for the law that an officer of the court does.

I bought a little board off of eBay. This board is essentially the innards of a powerbank for your own Li-Ion batteries (I use one 18650). The board has one micro-USB input and two USB A outputs (5V, up to 2A). So far, this board has not had any problems.
I would have given you a link to the listing, only the seller has apparently stopped on eBay.
I don't need a signature to draw attention to myself.
Maybe I should add a sarcasm warning now and again?
