From finance to healthcare, 7 cyberattack cases revealed
In the ever-evolving cybersecurity landscape, attackers are always looking for vulnerabilities in organizational environments. Rather than just targeting a single weakness, they are constantly looking for combinations of exposure and attack methods that can help them achieve their desired goals.
While numerous security tools exist, organizations often must contend with two major challenges: First, these tools often lack the ability to effectively prioritize threats, leaving security professionals unaware of which issues require immediate attention. Second, these tools often fail to provide context about how individual issues fit together and how attackers exploited them to gain access to critical assets. This lack of insight can lead to organizations either trying to solve every problem or, more dangerously, failing to solve any problems at all.
From complex attack paths that require multiple steps to extremely simple attack paths that require just a few steps, this research reveals a shocking reality: 75% of an organization’s critical assets could be compromised with their current security posture. Even more disturbing is the fact that 94% of these critical assets can be compromised in just four steps or fewer from the initial point of breach. This change emphasizes the need for the right tools to effectively predict and thwart these threats. Listed below are 6 real-world cyber attack path examples that can help organizations understand the ever-changing cyber threats.
Cyberattack Case 1: A large financial company
A large financial company was exposed to a man-in-the-middle attack due to an insecure DHCP v6 broadcast. An attacker could exploit this vulnerability to compromise approximately 200 Linux systems. This compromise could lead to data breaches, ransomware attacks, or other malicious activity.
Attack path: Exploiting DHCP v6 broadcast to execute a man-in-the-middle attack, and then attack the Linux system on the end computing device.
Impact: Approximately 200 Linux servers were compromised, potentially leading to data leaks or ransomware attacks.
Remediation: Disable DHCPv6 and patch vulnerable systems while educating developers on SSH key security.
Cyberattack Case 2: A large travel company
A major travel company failed to apply critical patches on neglected servers after a merger. This oversight leaves them vulnerable to known vulnerabilities such as PrintNightmare and EternalBlue, potentially compromising critical assets.
Attack Path: Neglected servers with no patches applied, including PrintNightmare and EternalBlue.
Impact: Risk of leakage of critical assets.
Remediation: Disable unnecessary servers to reduce overall risk.
Cyberattack Case 3: A large healthcare provider
A large healthcare provider faced the worrying prospect of an attack path leveraging authenticated user group permissions, potentially granting domain administrator access.
Attack Path: An attack path that leverages Authenticated Users group permissions to potentially grant domain administrator access.
Impact: Domain name leaked.
Remediation: Immediately cancel the permission to modify the path.
Cyberattack Case 4: A global financial institution
A global financial institution faced sophisticated attack paths that exploited service accounts, SMB ports, SSH keys, and IAM roles. The potential for critical assets to be compromised is very high.
Attack path: Complex paths involving service accounts, SMB ports, SSH keys, and IAM roles.
Impact: Compromises critical assets, with potentially catastrophic consequences if exploited.
Remediation: Quickly delete SSH private keys, reset IAM role permissions, and delete users.
Cyberattack Case 5: A public transportation company
In this case, a public transportation company discovered a direct path from the DMZ server to domain compromise, which could ultimately lead to the entire domain being compromised.
Attack Path: The direct path from the DMZ server to domain compromise.
Impact: A domain controller is compromised, with potential compromise to the entire domain.
Remediation: restrict permissions and delete users, delete suspicious user accounts.
Cyberattack Case 6: A large medical and health institution
A hospital had a vulnerability due to an Active Directory misconfiguration. This misconfiguration allows any authenticated user to reset their password, significantly increasing the attack surface.
Attack Path: Active Directory misconfiguration allows any authenticated user to reset their password, creating a wide attack surface.
Impact: Illegal takeover of legitimate accounts, business data leakage.
Remediation: Active Directory security hardening and comprehensive remediation planning.
Cyberattack Case 7: A large shipping and logistics company
A large transportation and logistics company discovered a sophisticated attack path that attackers could exploit to compromise the entire enterprise environment. The fix requires adjusting user roles and completely fixing the identified issues.
Attack Path: A complex attack path from the workstation computer to Azure.
Impact: Compromising the entire enterprise environment.
Remediation: Regularly adjust user roles, enhance monitoring of access activities, and improve network visibility.
Analysis of real cases of cyberattacks
What these scenarios have in common is that each organization has strong security measures in place, adheres to best practices, and trusts that they understand their risks. However, they often view these risks in isolation, creating a false sense of security.
Fortunately, these organizations are able to gain context-based understanding of their environment with the right tools. They learned how various issues can and do intersect and thus prioritized necessary remediations, to strengthen their security posture and mitigate these threats effectively.
