Security company Zerodium has upped the amount of cash on offer for the discovery of a zero-day bug in Apple iOS, taking it from $500,000 to $1.5m.
The firm explained that it has raised the bounty because iOS 10 is of a "higher difficulty" than previous releases.
"Zerodium payouts for eligible zero-day exploits range from $5,000 to $1.5m per submission," said the firm in its updated bounty information.
"The amounts paid by Zerodium to researchers to acquire their original zero-day exploits depend on the popularity and security strength of the affected software, as well as the quality of the submitted exploit."
Zerodium announced the zero-day bonus on Twitter, and founder Chaouki Bekrar followed up by confirming that Apple's software deserves premium prices.
Zerodium does not state explicitly what it uses the exploits for, but claims to have customers including "major corporations in defence, technology and finance in need of advanced zero-day protection, as well as government organisations in need of specific and tailored cyber security capabilities".
Zerodium has already paid out on the $1m bounty offer, dishing out the cash last November to one lucky firm for an iOS 9 crack.
It seems that the company has always been keen on peeling the Apple. "Apple iOS, like all operating systems, is often affected by critical security vulnerabilities," said the bounty information.
"However, due to the increasing number of security improvements and the effectiveness of exploit mitigations in place, Apple's iOS is currently the most secure mobile OS.
"But don't be fooled. Secure does not mean unbreakable, it just means that iOS currently has the highest cost and complexity of vulnerability exploitation and here's where the million dollar iOS 9 bug bounty comes into play."
A remote jailbreak on iOS 10 will earn $1.5m, but just $200,000 is on offer for the same on Android 7.0.
