Code signing and certificatesWhat is HP 4500 All In One Printer Driver for Mac. This is a story of those keys, and how a Hewlett Packard (HP) error caused problems for a lot of people.
Hp Envy 4500 Software Free For WindowsFor example, when you try to connect to your bank site, the site’s certificate will verify that the site really does belong to your bank. With web traffic, these certificates are used to encrypt the data, but they support more than just encryption.Certificates also allow for validation. Based operating system version.First, it’s important to understand that when I say “keys,” what I really mean is “certificates.” These certificates are similar to the ones that are the basis for secure communication between a web server and your browser. ![]() As we dug into the issue, however, we saw that there was a pattern in the screenshots we were seeing.The “malware” was being reported by the built-in anti-malware features in macOS, and there were a dozen or more different processes that macOS claimed “will damage your computer,” with a check box reading “Report malware to Apple to protect other users.” Sounds pretty scary, right?However, we noticed that this “malware” was all (mostly*) related to HP printing drivers. At least, that’s what they were saying. So, what happened?Last Thursday evening (October 22), we started seeing an influx of support requests from people complaining about some new malware that we weren’t detecting. With some digging, we found that the source of the issue was that the developer certificate used to sign these HP drivers had been revoked.Revoking a certificate is usually done by Apple when a piece of malware is discovered to be signed using that certificate. (XProtect is a basic form of anti-malware protection built into macOS, which aims to prevent malicious software from running.) The thought was that this was a false positive in other words, XProtect was erroneously detecting legitimate files as malicious.However, the timing of the last XProtect update didn’t line up with the very sudden and widespread emergence of the issue. Why did macOS think it was malicious?Initially, there was a lot of finger pointing at a recent XProtect update. Samples of the software that we obtained appeared to be legitimate, with no signs of malicious behavior. Adding text to slideshow for macAs an example, there was a case back in August where a developer named Charlie Monroe reported that his entire Apple developer account was deleted, and his code signing certificate was revoked. The impact of false positivesThis isn’t the first time that certificates have been revoked in error. We’re still seeing new cases reported days later. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer.Apple was able to reinstate the revoked certificate, which fixed the problem for some people, but not everyone. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. However, it turned out, according to a statement from HP given to The Register, that HP itself had erroneously requested that the certificate be revoked.We unintentionally revoked credentials on some older versions of Mac drivers. Some folks may never have contacted our support teams, and simply uninstalled our software, thinking they’d gotten infected while under our protection. I don’t know how Charlie Monroe is doing, but I suspect that a significant number of people who were using his software probably deleted it, and may never trust his software again.At companies like Malwarebytes, these events have the potential to result in hundreds or thousands of support tickets from customers asking why we didn’t detect this “malware,” or even why we’re blocking something legitimate (on the mistaken belief that this message is being shown by Malwarebytes). However, when there’s a certificate issue with a piece of Mac software, it affects everyone, everywhere, who is using that software.The fallout of these events can hit the developers hard. Mistakes happen, and Apple isn’t always to blame in cases like this. Don’t automatically believe that something is malware just because you Googled it and found sites calling it malware. Often, the software being recommended itself is a scam.It’s very important to be skeptical in your use of Google (and other search engines). Within hours on Friday, some of these sites – and fake YouTube videos referring to those sites – were already taking advantage of this chaos.The goal of these sites is to trick you into thinking you’re infected, so that you will download the software they recommend to remove the “virus.” In reality, there often is no actual malware, and the site gets paid an affiliate fee for every referral to the software in question. There has been an explosion in scam videos and web pages claiming to help you “remove” this “malware.” These scams work by taking advantage of common things people are searching for that they think are malware.For example, if you search for “will damage your computer” on Google right now, you will get a number of results offering to help you “remove will damage your computer” (yes, in exactly that nonsensical language). ![]()
