I'm one of the Adams Prize Organizers.Įach year, we update the team of independent specialists who could assess the quality of the competing projects: Wardle also published an email the person who contacted him said contained a link to the drive-by site that exploited the Firefox zero-day. This post will be updated as more information becomes available. Both he and independent reverse-engineer Vitali Kremez told Ars there appears to be a separate piece of malware that has backdoor and remote trojan properties. Wardle has yet to analyze it, so the threat it poses wasn't immediately clear.

The second hash Martin provided corresponds to a different piece of Mac software that, at the time this post went live, was undetected by all covered products. He said the change may be introduced in macOS 10.15. Wardle said he believes that Apple is in the process of updating XProtect and Gatekeeper so they scan all files, not just those with a quarantine bit. It turns out, the Netwire sample used not one, but two relatively primitive methods to maintain persistence on a Mac. This can be done using security tools such as KnockKnock or BlockBlock, which are freely available from Wardle.

"Why? When an exploit downloads a file (versus the user), that bit wouldn't be set." As a result, he added: "There would be no visual indication of an infection-unless the user went digging."īy digging, Wardle means manually inspecting a Mac to see what apps have permission to install themselves when the OS is booting. "In a nutshell, since XProtect and Gatekeeper only scan files that have the quarantine bit set, no, they would not have protected the user," Wardle, who is chief research officer at Digita Security, told Ars. The reason: the file lacked a "quarantine" bit that's only set when a user downloads the file from the Internet. But because NetWire was installed through a privileged process tied to Firefox, the exploit was able to bypass both protections. This is a protection that, by default, requires apps to be signed by a known developer before they can be installed. Normally, an app that's blacklisted by XProtect and unsigned should have posed no threat to most Mac users, since the software would have been blocked by default by both the built-in malware detector and Gatekeeper. Wardle also noticed that the malware sample wasn't digitally signed by its developer. It's surprising malware detectors hadn't obtained a detection signature from Apple. That was strange, because XProtect, the barebones malware detector built into macOS, had been detecting the NetWire sample since 2016. AdvertisementĪmong the things Wardle noticed early on was that the VirusTotal service showed that the malware was detected by only one of what at the time was 53 available malware detectors (at the time this Ars post went live, five out of 57 engines flagged it). The person claimed to have been "involved with a cryptocurrency exchange until fairly recently." The hash of the malware matched one of the hashes provided by Martin. On Thursday, macOS security expert Patrick Wardle published an analysis of Mac malware that came from someone who claimed it infected his fully up-to-date Mac through a zero-day vulnerability in Firefox.

We are working to notify other orgs we believe were also targeted." Martin also published cryptographic hashes of code used in the attack, along with IP addresses the code contacted. "We were not the only crypto org targeted in this campaign. "We've seen no evidence of exploitation targeting customers," Martin added.
The hackers then used the attack against employees of Coinbase, according to Philip Martin, chief information security officer for the digital currency exchange.Ģ/ We walked back the entire attack, recovered and reported the 0-day to firefox, pulled apart the malware and infra used in the attack and are working with various orgs to continue burning down attacker infrastructure and digging into the attacker involved.
On Monday, as Mozilla was readying a fix for the array.pop flaw, unknown hackers deployed an attack that combined working exploits for both vulnerabilities. Interestingly, a researcher at Google's Project Zero had privately reported the code-execution flaw to Mozilla in mid April.
#FIREFOX FOR MAC 2018 PATCH#
On Thursday, Mozilla issued a second patch fixing a privilege-escalation flaw that allowed code to break out of a security sandbox that Firefox uses to prevent untrusted content from interacting with sensitive parts of a computer operating system. Mozilla released an update on Tuesday that fixed a code-execution vulnerability in a JavaScript programming method known as Array.pop. Hackers exploited a pair of potent zero-day vulnerabilities in Firefox to infect Mac users with a largely undetected backdoor, according to accounts pieced together from multiple people.
