A message is posted in local stating the character is headed to null/clearing their hanger/disposing of loot from a corp theft. There will be a contract linked:
A contract will be setup that will contain various modules/implants that may be Faction/Deadspace or Officer class and there will be a cost to the contract, under You Will Pay, but the listed items will fool the mark into believing this is a cheap contract that will be very profitable to resell the contents.
What Happens Now
The mark will accept the contract but find out when they try to sell the individual items that they are either not as valuable as they expected and there is a very low sale volume.
How Can You Protect Yourself
Firstly, remember Rule #1, anything posted in local in a trade hub is going to be a scam and you should not accept any contract without seriously checking on the contents and issuer.
