Mathematician warns US spies may be weakening next-gen encryption
Quantum computers may soon be able to crack encryption methods in use today, so plans are already under way to replace them with new, secure algorithms. Now it seems the US National Security Agency may be undermining that process

#COM #CnC #Koadic
چند سال پیش، یک خط فرمان و کنترلی در Github ثبت شد که در نوع خودش، یک CnC بسیار جالب بوده.
این CnC مبتنی بر Component Object Model های سیستم عامل کار میکرده و از ظرفیت سیستم عامل بر علیه خود آن استفاده می نمود.
دلیل جذابیت این CnC نیز همین است، که بواسطه COM ها اقدام به انجام فرامید مد نظر یک تیم قرمز میکرده است، ویژگی اصلی آن استفاده از تکنیک HTML Smuggling بوده که توسط ActiveXObject ها اعمال میشده است.
حالا بعد از گذشت چندین سال، هنوز این CnC که با نام Koadic شناخته میشود، قابلیت استفاده دارد، البته با کمی تغییر منابع آن.
نوع پیلود های ایجادی این CnC برپایه زبان JavaScript و VBScript بوده است، که بواسطه cnoscript.exe و wnoscript.exe قابلیت اجرایی پیدا میکرده است.
اما در کنار آن دو، میتوان نوع پیلود های ایجادی را بواسطه MSHTA.exe که اجراگر فایل فرمت HTA است، نیز ایجاد نمود.
این روش ها اساسا، برای دور زدن محصولاتی مانند آنتی ویروس بسیار کارا هستند چرا که میتوان یک بدافزار را به چند Stage مختلف تقسیم نمود و به فرمت های مشروع سیستم عامل...

▪️A New Exploitation Technique for Visual Studio Projects
Tested version: 17.7.5 (VS2022 update at 2023.10)
این اولین بار نیست که از فایل پروژه های Visual Studio میشه بهره برداری کرد و کد های مخرب رو اجرا کرد. قبلا هم در سال 2021 گروه Lazarus APT از آسیب پذیری مشابه استفاده کرده بود و کد های مخرب رو در ساختار فایل پروژه اجرا میکرد.
این باگ نه تنها در ویژوال Visual Studio بلکه در JetBrains, VSCode و چند Text Editor وجود داره که باعث اجرای کد های مخرب در ساختار فایل پروژه میشه.

Crash Dump Error: How a Chinese Espionage Group Exploited Microsoft’s Mistakes
Redmond also acknowledged a failure of its internal systems to detect sensitive secrets leaking from crash dumps.
“The key material’s presence in the crash dump was not detected by our systems (this issue has been corrected),” the company said.
The company said the 2021 crash dump with signing key was subsequently moved from the isolated production network into its debugging environment on the internet connected corporate network.

Intro To Honeypots
There are also honeypots that exist as public services to collect and analyze various payloads.
While some of these services are simply built as a means for professionals (and cyber criminals) to test the detection rate of their payloads, they are equally leveraged as a means to distribute payloads to anti-virus companies and law enforcement looking to get an edge on new techniques used in the field.

Researchers Discover Critical Vulnerability in PHPFusion CMS
"Exploitation of this vulnerability has effectively two requirements," says Matthew Hogg, software engineer at Synopsys' Software Integrity Group, who discovered the vulnerability.
One of them is that the attacker needs to be able to authenticate to at least a low-privileged account, and the other is that they need to know the vulnerable endpoint.
"By fulfilling both criteria, a malicious actor would be able to craft a payload to exploit this vulnerability," Hogg says.

Why MSPs Should Focus Their Attention on Data Protection Services, Not Backup
Each additional backup solution means more cost and not reaping the benefits of scale that comes from serving many customers with the same solution.
Each solution means more complexity and more opportunity for something to go wrong.
When almost any other system goes wrong, the problem will be flagged immediately, usually by the customer complaining.
