Windows Defender Threat Detected : Trojan:Win32/Cerdigent.A!dha


Here's the latest AI info:

What is Happening?Defender is incorrectly flagging legitimate DigiCert Root CA certificates in the Windows registry as a high-severity threat. Users globally have reported that this detection lacks specific file paths or SHA hashes, typically affecting system registry keys like:HKLM\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\Certificates\0563B863....What You Should DoDo Not Panic: This is a known issue affecting many users simultaneously, which strongly indicates a glitch rather than a targeted attack.Check for Updates: Microsoft typically resolves these errors quickly. Open Windows Security > Virus & threat protection > Protection updates and click Check for updates to ensure you have the latest definitions that may have fixed this.Quarantine (Don't Delete): If the alert persists, choosing to Quarantine is safer than deleting, as these certificates are necessary for verifying secure website connections. Deleting them might cause browser errors or "untrusted connection" warnings.

I want to say that the world has gotten tougher. AI is really going to make keeping things secure as hard as possible ... The answer no one wants to hear "In order to be more secure you need to give up more".

Read this thread with interest and it prompted me to run a full Windows Defender anti-virus scan which gave the all clear. I don't use any other anti-virus other than Defender.

I will point out however, that it was only the day before this post, that I carried out a Reset this PC, (OS only from the Cloud) kept all my personal files. The purpose of the reset, was primarily because the previous week, I'd done a BIOS update on my MSI motherboard to update to the 2023 security certificates and then a few days later, I kept getting the PowerShell box popup each time I started up the PC. The reset worked its magic, all ok and overall, the PC is working much better anyway with a fresh OS on it.

On reading @dacrone post about automatic updates, I've hit the Pause updates button and I'll manually update.

I powered up both System One and System Two at 7 AM EDT. The first thing I do is a Windows Update on both systems.

Looking at my Defender Protection History: No recent actions.

I got hit with that FP as well just an hour ago, when Windows Defender did its scheduled daily passive scan. I restored the quarantined Certs from within Windows Defender. My primary security programs are ESET Smart Security Premium and Malwarebytes Standard Premium.

This is just another reason, I personally prefer to run paid security software, contrary to the current prevailing wisdom that free Windows Defender is all you need.

Have a great day.

Regards,
Phil

This morning I got the legitimate DigiCert; Trojan:Win32/Cerdigent.A!dha return from my Defender scan. Later I took it out of quarantine, and I downloaded a new Security Intelligence Update for Microsoft Defender Antivirus and did a rescan and it did not hit on that scan. So, all is good again I assume.

Microsoft Defender is detecting legitimate DigiCert root certificates as Trojan:Win32/Cerdigent.A!dha, resulting in widespread false-positive alerts, and in some cases, removing certificates from Windows.

According to cybersecurity expert Florian Roth, the issue first appeared after Microsoft added the detections to a Defender signature update on April 30th.

I got the Trojan:Win32/Cerdigent.A!dha alert this afternoon, me too.

I put it out of quarantine by restoring item, update my Security Intelligence and rescan without alert.

Otherwise, when I'm going in Registry Editor, in branch :

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\Certificates

the following certificates have not been restored :

0563B8630D62D75ABBC8AB1E4BDFB5A899B24D43
DDFB16CD4931C973A2037D3FC83A4D7D775D05E4

Is it serious ?

Thanks

    The Samsung NVMe PM9C1a 1024GB SSD does not use a Phison NAND controller. Instead, it uses Samsung's in-house developed Piccolo (S4LY022) 6-Core 4 Channel Controller. The PM9C1a utilizes a controller built using Samsung's 5-nanometer process and seventh-generation V-NAND technology. 🤔
