UnderConf. От сообщества – для сообщества

Keynote-спикеры и докладчики крупных конференций, авторы ваших любимых телеграм-каналов про ИБ, ведущие самых известных воркшопов и легенды индустрии в одном месте – на UnderConf, 29.09.

@crytech7, Сергей Голованов a.k.a. @sk1ks, @n0nvme и другие представят свои последние разработки и исследования, а Сергей Норд, локпикеры Autopsy Will Tell и хардварщики “Танец Роботов” параллельно проведут для вас топовые воркшопы.

На конференции также будет развернута лаборатория Pentest Lab, где можно будет разобраться в сценариях различных атак на части сетевой инфраструктуры компании.

В середине дня пройдут дебаты между Алексеем Гришиным и @i_bo0om о том, как расходятся интересы специалистов и бизнеса.

Подробная программа уже доступна на сайте.

Не рекламы ради, а просто поделиться, куда я решил заглянуть в честь начала отпуска

😈 [ Mandiant (part of Google Cloud) @Mandiant ]

🚨 Mandiant observed #LummaC2 stealers leveraging a new obfuscation technique to thwart analysis tools and stifle reverse engineering efforts.

Read about this tactic, and how we developed an automated method for removing this protection layer →

Got curious how the new App-Bound Chromium Encryption can be bypassed, so here’s a minimal PoC for decrypting the Local State key as a non-elevated user via an RPC call to the elevator service (path validation must still be taken into account though):

I just released my C2 I was working on, on my free time. Feel free to play around make your own forks if you like it. It needs a lot of work but it is a fully rust one with small implant and working sleep obfuscation.

Поговорили с Cyber Media о пентесте внутренних сетей, редтимах и рисках, получилось очень лампово:

🖥 Let's analyze one of the ways to bypass the smart screen and write our own simple cryptor that runs the shellcode:

🔥We have big news for you, NetExec now has a new protocol: NFS🔥

Main features:
- Detecting NFS servers
- List exported shares
- Recursive enumeration of shares
- Up&Download files

Many thanks to @mehmetcanterman who had the idea and implemented the protocol with me.

😈 [ nyxgeek @nyxgeek ]

I think most pentesters have used the classic OWA time-based user enum at some point. Or time-based enum in Lync.

What if I told you that time-based user enum lives on in Azure? And it's tied to Basic Auth.

Basic Auth is dead. Long live Basic Auth!

During a #redteam at @mod0 we discovered a limited but neat bypass for #printnightmare. I talked to @itm4n about it and he had an indepth look. Read about it here:

😈 [ Ohm-I (Oh My) @mcohmi ]

Dropping a POC and naming the specific person who found and disclosed it WHILE they are going through a disclosure process is a dick move, tbh.

Keep your POCs internal or in small groups until Drop Day.
