Apple products are known to be quite expensive, especially MacBooks.
But security researchers discovered a way to get the price down to as low as US$1 (S$1.30).
The researchers who discovered the hack work for a software security company called ERPScan.
They claim this security hole as usable on SAP point-of-sale (POS) machines.
The statement published on ERPScan's website said that the method exploited missing security checks in a SAP POS Xpress server.
Once a tool like a Raspberry Pi computer has been connected to a POS device, hackers can get to work remotely through the internet to change prices as they wish.
Fortunately, a patch for these SAP POS machines have been made available since August 21.
They advised retailers to quickly update their SAP POS solutions.
