Kerberoasting Attacks

One of RSI’s top priorities is keeping our clients’ daily work secure and seamless. Our team focuses on protecting business operations without disrupting productivity. Strong cybersecurity practices support both safety and efficiency across every environment we manage.

How RSI Protects Client Networks

RSI performs monthly and quarterly reviews to examine every aspect of a client’s network. These reviews include patch and firmware version checks on all devices. Our team verifies that antivirus software runs properly on every computer. Each review confirms that required security procedures stay current and effective.

The Role of Password Assessments

Password assessments play a critical role in our security process. During each assessment, RSI evaluates all Active Directory user account passwords against strict security conditions. These checks ensure passwords meet modern security standards. One key test determines whether passwords are vulnerable to Kerberoasting attacks.

What Is a Kerberoasting Attack?

A Kerberoasting attack involves a malicious actor, a standard Active Directory user account, and a target service or program. The attacker does not need administrative privileges to begin. Access to a single user account provides enough leverage to start the attack.

How the Attack Begins

An attacker first gains access to a valid user account on the domain. After signing in, the attacker already holds limited control of the environment. From there, the attacker searches for service accounts that may offer higher privileges.

Targeting Service Accounts

Service accounts often run important programs or services and may have administrative rights. Attackers look for these accounts to expand their access. Compromising one service account can open the door to larger parts of the network.

Abusing TGS Tickets

The attacker requests Ticket Granting Service tickets from the targeted service account. A standard user account can request and receive these tickets. Once received, the attacker attempts to crack the password hashes stored within the ticket.

Escalating Network Access

After cracking the password, the attacker signs in as the service account. This action grants administrative control over the associated program or service. At that point, the attacker is only a few steps away from full domain control.

Why Password Assessments Matter

Password assessments help identify vulnerabilities quickly and efficiently. When RSI detects a security risk, our team works directly with clients to guide the remediation process. Clear communication and accurate execution ensure smooth resolution without business disruption.

Staying Secure Every Day

This scenario shows how much damage someone can cause with limited access. Strong passwords and safe browsing habits remain essential for online security. These practices help prevent Kerberoasting and many other cyber threats.
