I docked to a equipment dock and sold a few turrets and upgrades. The revenue for that was about 8-15k worth of credits. I then recieved the steam notification for the Millionaire and Billionaire achievement and noticed that my balance had jumped to 9.223.372.036.854.775.808 credits.
This was on a rented multiplayer server from low.ms
How to recreate :
1. Obtain at least 2 items to sell, one of them has to have a value of 0 in the shop, the other can be any value
2. Find any station where you can sell upgrades or turrets (only tested on equipment docks though)
3. Sell the items, beginning with the 0-value-one (your balance should drop to zero at this point) and then after that, one with any value other than zero
4. Profit (literally)

Log is attached
Solution (for how to get rid of the money): Admin commands to give negative amounts of money barely did anything to get rid of the money. What eventually worked was sending the money as a mail and then delete that mail, though it took about half a minute until it began to withdraw the money.
