Exploit acquisition firm Zerodium announced this week that it’s no longer buying certain types of iOS exploits due to surplus, and the company expects prices to drop in the near future.
Zerodium said on Twitter it would no longer acquire iOS local privilege escalation, Safari remote code execution, and sandbox escape exploits in the next 2-3 months “due to a high number of submissions related to these vectors.”
The company says it expects prices to drop for one-click exploit chains that do not provide persistence.
Chaouki Bekrar, CEO and founder of Zerodium, said on Twitter that only pointer authentication codes (PACs) — they provide protection against unexpected changes to pointers in memory — and the difficulty to achieve persistence “are holding [iOS security] from going to zero.”
“iOS Security is fucked,” said Bekrar, noting that they are already seeing many exploits designed to bypass PAC and a few zero-day exploits that can help an attacker achieve persistence on all iPhones and iPads. “Let’s hope iOS 14 will be better,” he added.
Others also confirmed that the price of iOS exploits has been dropping.
According to its website, Zerodium is prepared to pay up to $2 million for iOS exploit chains that achieve persistence and require no user interaction. On the other hand, the same types of exploits targeting Android are worth up to $2.5 million.
The tech giant is running a public bug bounty program through which it’s prepared to pay out up to $1 million for exploits that achieve persistence, bypass PAC and require no user interaction.
