Some things never change ? such as SQL Authentication ?encryption?

Fat client applications running on (usually) Windows are still extremely common in enterprises. When I look at internal penetration tests or red team engagements for any larger enterprise, it is almost 100% guaranteed that one will stumble upon such an application.
These fat client applications have also usually been originally written many, many years ago, when security was maybe not one of the primary requirements. Whenever one encounters such a fat client application, or if this is perhaps part of your penetration test, one of the primary goals is to analyze how the application communicates with the rest of the world (or, usually, other internal systems).
While modern applications that you might encounter will most of the time consume some web services (usually SOAP, but I can see modern RESTful interfaces being consumed more and more), “traditional” fat client applications will most of the time connect directly to a database (again, since we’re looking at Windows environment primarily here, this will be most of the time a Microsoft SQL Server database). Such setup will appear quite simple...
The first step in identifying such an application will usually be to inspect its network traffic. In 99% of cases, this will be trivial to perform by using a tool such as Wireshark. This will allow not only to identify the target MS SQL Server, but also to inspect traffic on the wire. We will be looking for any traffic with destination TCP port set to 1433.
Again, due to the age of such applications, in almost every case I worked on, the data on the wire is most of the time sent in plain text, without any encryption. This is, obviously, very bad as we could easily perform a MitM attack (see more below), but the TDS protocol will, luckily, have one step encrypted: authentication.

A Gentle Reminder: The Evolving Nature of Digital Scams
Published: 2023-08-16
Last Updated: 2023-08-16 08:45:06 UTC
by Yee Ching Tok (Version: 1)
Considering the global turbulence from destabilizing events such as physical conflicts, freak weather and pandemics, financial wealth has never been more critical for a nation and its citizens so that daily life can continue. Money is needed for daily necessities such as food, medication, appropriate clothing and fuel. When faced with unexpected events such as retrenchment and newly detected health issues, citizens would also have to tap on the monetary buffer that should have been built up during less challenging times. Considering the current state of international affairs and employment prospects, one potential way to disrupt a nation’s peace and stability could be stealing their citizens’ monetary savings via financial scams and fraud.
Unlike conventional cyber-attacks such as phishing, where adversaries target to harvest credentials to gain access to accounts, digital scams aim to bypass the harvesting of credentials but instead attempt to convince the victim to authenticate and part with their assets directly. A multitude of factors could cause this change. For example, end users have gotten savvier about phishing attacks and stopped interacting with such messages that try to masquerade as a well-known entity (e.g. shipping companies/social media sites). Applications could also have implemented additional security controls such as two-factor authentication (2FA), preventing adversaries from directly using credentials to authenticate with the target application. The main issue is that adversaries are likely to employ some means to wire away a victim’s hard-earned money and keep on doing so should these tactics be successful.
