Researchers Uncover macOS and Safari Exploits at Pwn2Own 2017

The seventeenth annual CanSecWest security conference is underway in downtown Vancouver, British Columbia, where researchers are competing in the 10th anniversary Pwn2Own computer hacking contest for over $1 million in prizes. Day one results have already been published over at the Zero Day Initiative website, with a couple of successful Mac-related exploits already appearing in the list of achievements. Independent hackers Samuel Groß and Niklas Baumstark landed a partial success and earned $28,000 after targeting Safari with an escalation to root on macOS, which allowed them to scroll a message on a MacBook Pro Touch Bar. In a partial win, Samuel Groß (@5aelo) and Niklas Baumstark (@_niklasb) earn some style points by leaving a special message on the touch bar of the Mac. They used a use-after-free (UAF) in Safari combined with three logic bugs and a null pointer dereference to exploit Safari and elevate to root in macOS. They still managed to earn $28,000 USD and 9 Master of Pwn points.Later in the day, Chaitin Security Research Lab also targeted Safari with an escalation to root on macOS, finding success using a total of six bugs in their exploit chain, including "an info disclosure in Safari, four type confusion bugs in the browser, and a UAF in WindowServer". The combined efforts earned the team $35,000. The participating teams earned a total of $233,000 in prizes on day one, including a leading $105,000 earned by Tencent Security, according to published details. Other software successfully targeted by contestants include Adobe Reader, Ubuntu Desktop,

Researchers Uncover Multiple OS X and Safari Exploits at Pwn2Own 2016

The sixteenth annual CanSecWest security conference is underway in downtown Vancouver, British Columbia, and researchers participating in the Pwn2Own computer hacking contest have already discovered multiple vulnerabilities in OS X and the Safari web browser on the desktop. On day one of the event, independent security researcher JungHoon Lee earned $60,000 after exploiting both OS X and Safari. Lee uncovered four vulnerabilities in total, including one exploit in Safari and three other vulnerabilities within the OS X operating system, according to security firm Trend Micro.JungHoon Lee (lokihardt): Demonstrated a successful code execution attack against Apple Safari to gain root privileges. The attack consisted of four new vulnerabilities: a use-after-free vulnerability in Safari and three additional vulnerabilities, including a heap overflow to escalate to root. This demonstration earned 10 Master of Pwn points and US$60,000.Meanwhile, the report claims that the Tencent Security Team Shield group successfully executed code that enabled them to gain root privileges to Safari using "two use-after-free vulnerabilities," including one in Safari and the other in a "privileged process." The researchers were awarded $40,000 in prize money. The five participating teams earned a total of $282,500 in prizes on day one, including a leading $132,500 earned by the 360Vulcan Team, according to the report. Other web browsers and plugins that were successfully targeted include Adobe Flash, Google Chrome, and Microsoft Edge on Windows. Apple representatives have attended
