ADExplorerSnapshot

ADExplorerSnapshot is an AD Explorer snapshot ingestor for BloodHound.
AD Explorer allows you to connect to a DC and browse LDAP data. It can also create snapshots of the server you are currently attached to. This tool allows you to convert those snapshots to BloodHound-compatible JSON files.

VPN Overall Reconnaissance, Testing, Enumeration and Exploitation Toolkit (Vortex)

A very simple Python framework, inspired by SprayingToolkit, that tries to automate most of the process required to detect, enumerate and attack common O365 and VPN endpoints (like Cisco, Citrix, Fortinet, Pulse, etc...).

Features:
— User Search and Collection
— Password Leaks
— Main Domain Identification
— Subdomain Search
— VPN Endpoint Detection
— Password Spraying/Guessing attacks
— Search profiles on Social Networks

Apache APISIX Dashboard — Unauthorized RCE (CVE-2021-45232)

Attackers can access certain interfaces without logging in to Apache APISIX Dashboard, thus making unauthorized changes or obtaining relevant configuration information such as Apache APISIX Route, Upstream, Service, etc., and cause problems such as SSRF, malicious traffic proxies built by attackers, and arbitrary code execution.

Redash Exploiting (CVE-2021-41192)

Redash is a package for data visualization and sharing.
If an admin sets up Redash versions 10.0.0 and prior without explicitly specifying the REDASH_COOKIE_SECRET or REDASH_SECRET_KEY environment variables, a default value is used for both that is the same across all installations. In such cases, the instance is vulnerable to attackers being able to forge sessions using the known default value.

Bypass Rate Limits in Web Applications and API's.

— What is Rate Limit

Rate limiting is a process to limiting the number of request an user can make to a web server in an span of time. This can be achieved by implementing IP based, Session Based rate limits on web server.

—Where to Look for Rate Limit Bugs

Place like :
— Login/Signup pages
— Register Pages
— 2FA codes
— Confirmation Codes

...and any other request which if bruteforce will allow attacker to achieve anything malicious should be check for "No Rate Limit" issue.

[Bypass 1] - Using Null Chars

%00, %0d%0a, %09, %0C, %20, %0

Example:
— Bruteforce with [email protected]
— After some time you will be blocked
— Now Bruteforce with [email protected]%00 and check if you are able continue bruteforce it

[Bypass 2] - Adding Spaces

A webserver may strip off extra spaces added to email/username at the backend, Which may allow you to bruteforce the same email by appending an extra space every time you are blocked.

[Bypass 3] - Host Header Injection

Try Modifying Host header of the request after being blocked by the server

Change Host: www,newsite,com
Change Host: localhost
Change Host: 127.0.0.1

[Bypass 4] - Changing Cookies

Try changing Session cookie after being blocked by the server. This can be achieved by figuring out which request is responsible to set session cookies to the user and then use that request to update session cookie everytime you are blocked.

[Bypass 5] - X-forwarded-For

— dig target,com
— Change The X-Forwarded-For: IP Address

This may confuse WAF/server/loadbalancer, as if requests are being forwarded to another host but will be forwarded to same target host hence will allow you to bypass the rate limit.

[Bypass 6] - Confuse server with correct attempts

If the server is blocking you after 20 attempts, Try bruteforcing with 19 attempts and use your credentials to login to your account on 20th attempt and then repeat the process.

[Bypass 7] - Updating target Paths

Appending random param=value may sometimes bypass rate limit on the endpoint

Eg:
— Bruteforce /api/v1/users/<id>
— Got blocked after 200 attempts
— Now Bruteforce /api/v1/users/<id>?xyz=123
— Change the param=value after each 200 attempts

[Bypass 8] - IP based Rate limits

IP based rate limits can be easily bypassed by changing the Ip address of your machine. The alternative would be using IP Rotate Burp Extension.

Undetected Azure AD Bruteforce Attack

In late June 2021, Secureworks Counter Threat Unit researchers discovered a flaw in the protocol used by the Azure Active Directory Seamless Single Sign-On feature. This flaw allows threat actors to perform single-factor brute-force attacks against Azure Active Directory (Azure AD) without generating sign-in events in the targeted organization’s tenant.

Bypass Defender AV static detection:

If you name a malicious file *.log Defender doesn't scan it.

UPD:
DumpStack (by any file number) can bypass MDE easily with no detection as mimikatz or eicar mode.
The malicious file can be shown in the console but not identified as malicious.

An ‘Attack Path’ Mapping Approach to CVEs 2021-42287 and 2021-42278

This post provides Splunk SPL queries for detecting the attacks described in Charlie’s blog, using only Windows Security Log events from a domain controller. Furthermore, this post only examines a subset of the Windows Event logging data source
