This aligns with the way I used runas and entered my credentials interactively.

4624 – An account was successfully logged on.Ī 4624 event was logged with a Logon Type of 2, which means an interactive logon.

4648 – A logon was attempted using explicit credentials.

On my local workstation, I will see the following events:

Now let’s see what native Windows events were logged. That gives us a baseline for normal NTLM authentication behavior that does not involve pass the hash. Practical Guidance for Fighting IT Monsters Next, I used the Sqlcmd utility to connect to a Microsoft server by its IP address. This command will generate NTLM authentication to the SQL database: Sqlcmd –S įor good measure, I will also run the SELECT SYSTEM_USER command to show the user I am authenticated as: To generate these events, I launch a new command prompt as an administrative user, using the account’s actual password: Pass the hash relies on NTLM authentication, so we need to first understand what events are normally generated during normal NTLM logon activity.

Getting a Baseline: Understanding the Events Logged during the Normal NTLM Authentication Process This post explains exactly what to look for in the native Windows event logs to detect pass the hash, and offers additional options for spotting - and even preventing - these attacks. This tactic enables them to bypass normal system access controls to move laterally within the environment.

In particular, one common technique is pass-the-hash: Hackers use stolen password hashes to authenticate as a user without ever having the user’s cleartext password.

SafeBIOS now provides the unique ability to generate Indicators of Attack on BIOS configurations, including changes and events that can signal an exploit,' David Konetski, VP Client Solutions Group CTO at Dell said in a blog post.Attackers frequently rely on lateral movement techniques to infiltrate corporate networks and obtain privileged access to credentials and data. 'Organizations need the ability to detect when a malicious actor is on the move, altering BIOS configurations on endpoints as part of a larger attack strategy. With stealth access to one of the compromised systems in an enterprise IT network, sophisticated attackers could move laterally throughout the infrastructure.Īccording to Dell, the controls offered by SafeBIOS can quickly mitigate the risk of BIOS tampering by bringing them to your attention timely, allowing you to quarantine infected PCs.

Attacks against the BIOS are typically hard to detect because they are invisible to antivirus and other security software installed on the system,.Malware in BIOS remains persistent and doesn't get away even when you format or erase your entire hard drive,.Once a hacker takes over the BIOS, he can stealthily control the targeted computer and gain access to the data stored on it,.

Changes to the system BIOS settings could allow malicious software to run during the boot process,.

Protecting the BIOS program is crucial because: Computer manufacturing giant Dell has released a new security tool for its commercial customers that aims to protect their computers from stealthy and sophisticated cyberattacks involving the compromise of the BIOS.ĭubbed ' SafeBIOS Events & Indicators of Attack' (IoA), the new endpoint security software is a behavior-based threat detection system that alerts users when BIOS settings of their computers undergo some unusual changes.īIOS (Basic Input Output System) is a small but highly-privileged program that handles critical operations and starts your computer before handing it over to your operating system.
