/cc @bsi Was ist eigentlich der "Prozess" für vollständig öffentliche Lücken zu denen es seit über einer Woche noch nicht einmal eine CVE Nummer gibt?

Edit: Patch and CVE number CVE-2026-33825 available by now. Took 6 days though.

Oh, look at that! 🎉 Windows Defender, the "all-powerful" guardian of your PC, is now moonlighting as a #vulnerability. 🤦‍♂️ But don't worry, aspiring hackers! There's a course for this "ethical" hacking, because who wouldn't want to learn how to exploit the software designed to protect you? 😂

Nowy wariant metody ClickFix – cyberprzestępcy rezygnują z Win+R na rzecz Win+X i Terminala Windows

Badacze bezpieczeństwa z Microsoft Defender ostrzegają przed nowym wariantem kampanii malware, w której cyberprzestępcy za pomocą phishingu nakłaniają użytkowników do instalacji złośliwego oprogramowania typu infostealer (Lumma Stealer). Atak opiera się na technice ClickFix, polegającej na przekonaniu użytkownika do uruchomienia złośliwych poleceń PowerShell.TLDR: Schemat ataku jest dosyć prosty. Korzystając z socjotechniki...

Windows Security Not Opening? 😟

You’re not alone. If Windows Security won’t open in Windows 11 or 10, these 8 recommended fixes can help restore Defender, fix blank screens, and keep your PC protected—no reinstall needed.

Finally did something I've been meaning to do for a LONG time, fully disabled Defender on this HP laptop with Windows 10. Been driving me nuts, when I need to test things, and how Defender restarts automatically if you restart your laptop. The guide I found that was amazing and worked was this: https://www.izoate.com/blog/how-to-disable-windows-defender-permanently-on-windows-10-and-windows-11.

I really had to dig around in the registry. Just turning it off or messing with the Group policy stuff didn't work. I had to make a backup, and go manually turn off everything I could in the registry. I appreciate safety and whatnot, but fuckin Windows. 🙄 😂

This makes perfect sense, right?

Excluding a process from windows defender will be detected.

Excluding a process and a path from windows defender won't.

(this is windows 10 on it's last security update)

Your device is no longer receiving security updates but Still gets a security update for Windows Defender.

Augen auf beim Download!
In einer neuen Malvertising‑ und SEO‑Poisoning‑Kampagne, die vom Conscia’sForensicInvestigation-Team oder auch Blackpoint‑SOC entdeckt wurde, bewerben Datenhaie eine gefälschte Website, die erscheint, wenn User:innen z. B. in Bing nach „Teams download“ suchen. Die Original-MS-Website wird imitiert und auch die Downloaddatei sieht zunächst "normal" aus. Doch der Installer verbreitet das Oyster‑Backdoor‑Tool auf Windows‑Geräten und verschafft Angreifern Fernzugriff auf infizierte Geräte, sodass diese Befehle ausführen, weitere Payloads bereitstellen und Dateien übertragen können. Die Angreifenden zielen in erster Linie auf Firmennetzwerke.
In diesem Fall wurde durch die Attack Surface Reduction (ASR)‑Regeln von Microsoft Defender der Angriff neutralisiert: Die Malware wurde daran gehindert, Kontakt zu ihrem Command‑and‑Control‑Server herzustellen.
Auch wenn dieser und ähnliche Angriffe abgefangen werden konnten, muss doch mit weiteren Varianten gerechnet werden. Daher gilt:
Download von ausführbaren Dateien nur von der Originalquelle oder sorgfältig geprüften vertrauenswürdigen Hubs (z. B. große Verlage mit digitalen Portalen). Prüfen Sie Links wohin diese führen, bevor Sie klicken.

My PC's fans are currently really loud as #FanControl has triggered #WindowsDefender. Either fan control has been hacked or Windows Defender is shit and is falsely detecting the software as malware.

Mashable: Hackers found a way around Microsoft Defender to install ransomware on PCs, report says. “Windows users should think about reinforcing their antivirus software. And while Microsoft Defender should provide a line of defense against ransomware, a new report claims that hackers have found a way to get around the ransomware tool to infect PCs with ransomware.”

Uninstalling the #MicrosoftStore version of #Python and disabling #WindowsDefender so the #torch dlls properly install so I can run comfyui-zluda, a fork of #comfyui which uses #zluda which is a shim for #CUDA applications to use #AMD #HIP SDK so I can download #stableDiffusion and run it on my #Radeon #GPU because #Amuse won't let me generate porn.

Monthly reminder that #Windows11 fucking sucks ass.

Trying to troubleshoot why a software didn't start and Windows Defender false-positive a DLL that now can't restore.

Great start for a monday.

Ein Sicherheitsforscher enthüllt mit "Defendnot" eine kritische Schwachstelle im Windows Security Center. Das Tool täuscht ein falsches Antivirenprogramm vor und deaktiviert so den #WindowsDefender. https://winfuture.de/news,151018.html?utm_source=Mastodon&utm_medium=ManualStatus&utm_campaign=SocialMedia

@SecurityWriter Individual hobbyists who develop games and other programs for Windows often ask the user to bypass SmartScreen because the dev can't afford a commercial code signing certificate. Is that also just like "disable their security software"?
