This can happen even if a company performs extensive risk assessments and utilises perimeter protection devices like firewalls. For instance: Additionally, the concept of zero trust, which requires a multi-faceted approach, can be applied to defend against lateral movement attacks. Using the right cmdlets, a threat actor can look at group memberships, observe service accounts, find out password policies and identify important servers like domain controllers. Therefore, for lateral movement based on asset attacks, we need to ensure the basics are being done well week after week, month after month, and year over year to ensure we do not expose cracks in our security posture that could lead to a vulnerability and exploit combination. Another key thing to remember is that you can use the same tools hackers use to perform penetration tests. Every company on this planet, big or small, is susceptible to a data breach. After gaining an initial foothold, the first thing an attacker might do is a network scan. While a hacker might initially succeed in infiltrating an environment via a number of methods, such as an opportunistic phishing attack, or a targeted attack based on stolen credentials or an exploit, lateral movement is the means to find data of value, compromise additional assets, and, ultimately, execute malware for reconnaissance and command and control. Additionally, the ability to centrally assert control over sessions, including pausing and terminating them, is a powerful defensive capability. In 2004, he joined eEye as Director of Security Engineering and was responsible for strategic business discussions and vulnerability management architectures in Fortune 500 clients. Get to Know: Vanessa Pegueros, OneLogin, AT&T Wireless, Cybersecurity and aviation: Combatting the key threats. A successful attack is based on software flaws and not credentials used for the interaction of resources when modern security strategies are deployed. Using these techniques, they can move from one computer to the next and ultimately gain domain administrator privileges. At this phase, they are actively trying to jump from one machine to another. The rise of social engineering techniques makes it much easier; for example, a phishing email to a doctor's office with a from address that appears credible and a legitimate-looking patient ID in the subject line might be sufficient to convince the doctor to open the email. All privileged sessions should be monitored for unusual activity (i.e. Identification of active network connections also happens during this phase with the help of tools such as Netstat. They will then usually start compiling a list of target domain controllers with credential information or database servers that hold valuable data assets. Here, the attackers begin exploring the hospital's network to spot weak nodes and sensitive data. This raises the obvious question—how do you protect against lateral movement when it can occur in so many different ways? Description. To a threat actor, lateral movement is a crucial strategy. Try thinking of the approach to stopping lateral movement in these terms. Keeping a watchful eye on network logs and correlating incidents to derive insights can aid healthcare IT administrators in detecting lateral movement. Applying the principle of least privilege, just-in-time privileged access management, Implementing Privileged Credential Management, BeyondTrust Expands Cloud Leadership with Endpoint Privilege Management Delivered as-a-Service, Highlights & Takeaways from BeyondTrust’s Customer Advisory Board Meeting in Napa Valley, Brute Force Attacks (including techniques like Password Spraying). Try thinking of the approach to stopping lateral movement in these terms. The techniques for lateral movement can be based on the resource’s asset or privilege characteristics, and include resources that span a human identity all the way through unpatched vulnerabilities on an operating system. There are numerous ways an attacker can move through a network, and it’s important to understand how this is generally done. A network scan will show them the list of active hosts on the network along with their IP addresses. These tools alert security professionals the moment certain risky conditions are detected. A security solution that tracks the logs of both users and systems is required to obtain a wholesome picture. Lateral movement by privileged attack vectors can be drastically curtailed by effectively executing the universal privilege management fundamentals. Apart from third-party applications, cyberattckers also use several built-in Windows tools to avoid detection. It is not authorized to accept deposits or trust accounts and is not licensed or regulated by any state or federal banking authority. Apart from using the right tools, companies must educate users about the importance of security hygiene. Lateral movement takes up the maximum duration in a cyber kill chain; the presence of hackers in the network for long periods of time makes it easier for IT admins to spot and contain attacks. At this phase, they are actively trying to jump from one machine to another. Such an incident would create havoc in the hospital's operations, potentially leading to life-threatening consequences; for example, exploiting a medicine infusion pump to alter the rate at which the drug is released into a patient's blood stream can instantly cause severe side effects or even death. The resource can be abstract like an identity or software in the form of a container. The earlier attack stages like cloud events and password spray activities were oftentimes missed or sometimes not linked with activities observed on the endpoint. Remember, lateral movement can happen in between resources and it is that inappropriate trust between them that should be prevented to mitigate the threats of lateral movement. Understanding the cyber-attack chain model can help IT security teams put strategies and technologies in place to “kill” or contain the attack at various stages, and better protect the IT ecosystem. While the internet of medical things (IoMT) market has grown and diversified rapidly, 71 percent of the medical instruments that run Windows operating systems still use versions that will expire by January 2020. For now, however, we’ll just have to keep focusing our efforts on combating it the best we can. More often than not, cybercriminals get into a network using malware. – an attacker opportunistically exploits a vulnerability, or uses a compromised credential, etc., to gain an initial beachhead in your environment. These stages constitute the cyberattack life cycle, also known as a cyber kill chain. Our conversations on lateral movement should always include the resources involved in a technology implementation and how are we securing privileged access and maintaining foundational security to protect the asset. After all this investigating, the attacker will know exactly what machines to target to begin moving laterally. Asset attacks are typically addressed, or at least mitigated, through vulnerability, patch, and configuration management. Using unsupported, outdated software for medical equipment favors cyberattackers and entices them to exploit this obvious vulnerability.
