The cyber security community is still reeling after the revelation of the KRACK security vulnerability that breaks down Wi-Fi encryption. Now it seems another Wi-Fi-based bug has also been discovered.
Presented at the global Pwn2Own hacking contest in Tokyo, a team of researchers demonstrated how a separate Wi-Fi bug could be exploited to gain entry to iPhones and install malicious apps on them without the owners knowledge.
The details of the threat haven’t been made public yet as Apple hasn’t had time to patch the flaw. It’s discovery was enough to net the Tencent Keen Security Lab the top prize of $110,000.
The hacking contest is set up and run by the Zero Day Initiative, which seeks to find vulnerabilities in popular products and services and alert the manufacturers in time.
According to the official event page , the Tencent Keen Security Lab team used “code exectution through a WiFi bug” to escalate “privileges to persist through a reboot.” Effectively breaking through an iPhone’s lock screen through a Wi-Fi network.
The flaw will be relayed to Apple which could offer a software patch to close the gap.
“Once we verify the research presented is a true 0-day exploit, we immediately disclose the vulnerability to the vendor, who then has 90 days to release a fix,” explains the Zero Day Institute.
“Representatives from Apple, Google, and Huawei are all here and able to ask questions of the researchers if needed.
“At the end of the disclosure deadline, if a vendor is unresponsive or unable to provide a reasonable statement as to why the vulnerability is not fixed, the ZDI will publish a limited advisory including mitigation in an effort to enable the defensive community to protect users.”
As ever, from a security standpoint it is always advisable to make sure your phone is running the latest OS version and you closely vet the permissions you give to certain apps.
