Read along for how to fully remove Adobe Flash from your Mac. And with that, Adobe is strongly recommending users uninstall it from their computers immediately. Clearly in the never ending cat & mouse game between the attackers and Apple, the attackers are currently (still) winning.After a three-year warning, the end of Adobe Flash has officially happened. However the attackers’ ability to agilely continue their attack (with other notarized payloads) is noteworthy. Unfortunately these new payloads are (still) notarized:īoth the old and “new” payload(s) appears to be nearly identical, containing OSX.Shlayer packaged with the Bundlore adware. Interestingly, as of Sunday (Aug 30th) the adware campaign was still live and serving up new payloads. However, the cat and mouse game continues, as Wardle detailed on his blog:Īs noted, Apple (quickly-ish) revoked the Developer code-signing certificate(s) that were used to sign the malicious payloads. We thank the researchers for their assistance in keeping our users safe.” Upon learning of this adware, we revoked the identified variant, disabled the developer account, and revoked the associated certificates.

In a statement, a spokesperson for Apple told TechCrunch: “Malicious software constantly changes, and Apple’s notarization system helps us keep malware off the Mac and allow us to respond quickly when it’s discovered. The security threat of this adware looks to be relatively low but of course, is still something Apple wants to prevent.

Wardle said that means Apple did not detect the malicious code when it was submitted and approved it to run on Macs - even on the unreleased beta version of macOS Big Sur, expected out later this year.Īfter Dantini and Wardle discovered the malware, Apple fixed the issue on August 28th. Wardle believes this is the first time malware like this was mistakenly approved by Apple during the notarization process and it affects recent macOS versions, even the Big Sur beta. Shlayer is a kind of adware that intercepts encrypted web traffic - even from HTTPS-enabled sites - and replaces websites and search results with its own ads, making fraudulent ad money for the operators. Wardle confirmed that Apple had approved code used by the popular Shlayer malware, which security firm Kaspersky said is the “most common threat” that Macs faced in 2019. Notably, the “Shlayer” malware was deemed by Kaspersky as the most likely threat for a Mac to experience in 2019. Reported by TechCrunch, security researchers Peter Dantini and Patrick Wardle discovered that Apple accidentally notarized a popular malware hiding inside a Flash Player update. When approved, that gives the green light to the macOS Gatekeeper feature that an app is safe to run.

In contrast, Mac users can download apps from the App Store as well as anywhere on the internet.Įven though Mac apps downloaded outside of the App Store don’t go through the same review process, Apple still requires them to be notarized (as of last year), which puts software through a security review looking for things like malicious code.
IOS is more locked down and naturally more secure than Mac overall because all apps need to be downloaded through the App Store. While the original flaw was quickly fixed, another similar one has popped up. In the case of the Mac, a new report highlights how Apple accidentally approved one of the most common malware threats to run on recent versions of macOS.
While Apple’s devices are typically more secure than the competition, that doesn’t mean they’re immune to flaws.
