Overview

Agent Tesla is an advanced spyware Remote Access Trojan (RAT) written for the .NET framework and has been active seen 2014. It can easily steal sensitive information from an infected machine and collect data like keystrokes as well as login credentials used in various browsers while also mailing clients linked with the victim's machine. 

Tactics & Techniques

As stated above, this malware spreads through phishing emails and once it enters into the system, it hides itself with the help of various techniques which makes it difficult to detect it before any damage. After the successful breach, Agent Tesla extracts all the information related to search engines like login credentials, keystrokes, screenshots, etc. in order to compromise the users' accounts. It main targets are the industries related to energy, logistics, finance, government sector, etc.

Prevention

In order to mitigate the risks related to Agent Tesla, we can perform following steps:
  • Anti-Phishing Protection- As this malware attacks via phishing emails, we can apply anti-phishing solutions that can analyze as well as detect the malicious contents within an isolated environment.

  • Content Disarm & Reconstruction (CDR)- This one basically filters or sanitize the files before allowing them to enter the user's inbox, thus protecting it against any malfunctions.

  • Endpoint Detection & Response- Since it is very difficult to identify this malware before it reveal itself, the endpoint security solutions can easily destroy the malware once it is revealed.

  • Multi-Factor Authentication (MFA)- As we all know by now, MFA makes it nearly impossible for threat actors to make use of any stolen credentials. 

  • Zero Trust Access Management- This one can successfully limit the damage done by the malware via an infected account.

  • User Behavior Monitoring- Regular monitoring of an account's behavior will significantly help in identifying a compromised user account.

  • Employee Security Training- It is very crucial to make cybersecurity awareness training essential for the employees to identify and respond accordingly during a breach situation in order to minimize the risks related to these attacks.

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan

  Extract Data from Unstructured String Fields Unstructured string fields often contains the Security log data and requires parsing to extract data. There are multiple ways of pulling information from string fields in KQL and the two primary operators used are extract and parse.  Extract It gets a match for a regular expression from a text string. You can convert the extracted substring to the indicated type.  Arguments regex- A regular expression. captureGroup- A positive int constant indicating the capture group to extract. 0 stands for the entire match, 1 for the value matched by the first '('parenthesis')' in the regular expression, 2 or more for subsequent parenthesis.  text- A string to search. typeLiteral- An optional type literal. If provided, the extracted substring is converted to this type.  Returns If regex finds a match in text- the substring matched against the indicated capture group captureGroup, optionally converted to typeLiteral. If there's no mat
