Pass the hash attacks can be detected by analyzing and correlating log data with user behavior anomalies. To detect the attack in your network, you should configure your security tool to detect this criteria: Detection mechanism Source Host Event ID: 4624 An account was successfully logged on Log...
Identity-based attacks, such as pass the hash attacks, where adversaries pose as legitimate users are particularly difficult to detect because most traditional cybersecurity solutions cannot differentiate between a real user and an attacker masquerading as one. Protecting against pass the hash attacks is...
Because pass the hash exploits the features and capabilities of the NTLM protocol, the threat of pass the hash attacks cannot be eliminated completely. Once an attacker compromises a computer, pass the hash becomes only one of the malicious activities that can be executed. Unfortunately, there are...
In the last posting, we spoke aboutPass-The-Hash attacks (PtH)and why we should all care about them. I’d like to put the topic to bed with a discussion around some of the changes we’ve made here at Microsoft over the last couple of months to combat this type of attack. Firs...
salt是计算一个hash时使用的随机数据块,这使得hash更难破解和重用。必须注意的是,NT散列并没有使用salt。因此,它很容易受到"预计算攻击"(precomputation attacks):也就是可以有个映射表(如彩虹表),可以根据hashes快速找到对应的明文密码。此外,相同的密码可以仅基于NT hashes来识别,不需要破坏加密(breaking the ...
How To Detect Pass-The-Hash Attack? It might be difficult for enterprises to pass the hash attacks detection since NTLM authentication is handled by every workstation and server. Monitor NTLM authentications (especially for distant connections) for changes in patterns of user behaviour, such as a...
首先先来看看历史上微软对pass the hash攻击出的文档: http://download.microsoft.com/download/7/7/A/77ABC5BD-8320-41AF-863C-6ECFB10CB4B9/Mitigating%20Pass-the-Hash%20(PtH)%20Attacks%20and%20Other%20Credential%20Theft%20Techniques_English.pdf ...
Even though the pass-the-hash (PtH) attack was originallypublished by Paul Ashton in 1997 and several white papers andtech briefs have been written on the topic1, these types of attacks have recently come to the forefront again. Given this reality,organizations need advanced solutions that can...
About Pass-The-Hash Attacks One type of attack, in particular, began to incite significant concern across the organization—an advanced threat known as a Pass-the-Hash attack that targets Windows operating systems. These types of attacks generally involve cyber attackers who seek to capture account...
Pass-the-Hash attacks and Windows Windows systems are typically the favored target of Pass-the-Hash attacks, though they can also compromise other operating systems such as Linux and Unix. Because of its SSO function, Windows is a prime target since it only requires users to enter their passwo...
