Organizations need to continually bolster and adjust their security measures as cyber attacks evolve, becoming more sophisticated. One such attack that has gained prominence recently is pass-the-hash (PtH), so in this blog post, we'll investigate its nature, mechanism, and how Cyberark can assist with prevention efforts.
What Are Pass-the-Hash Attacks?
Criminal actors can gain illicit entry to an organization's IT systems through pass-the-hash attacks, a form of credential theft. These attacks exploit vulnerabilities within Windows operating system authentication system to steal password hashes in order to gain entry and gain access to its resources.
Pass-the-hash attacks differ from password cracking attacks by taking advantage of stolen hashed passwords used for authenticating users on Windows networks. Once these hashes have been taken advantage of, criminals gain access to any network resources permitted for that user and thus cause further chaos within an organization even after changing his or her password. This type of attack must be considered particularly alarming; once stolen hashes can allow access to sensitive data even after its passwords have been changed!
What are Pass-the-Hash Attacks' Mechanisms?
Acquisition, retrieval and exploitation represent the three core stages of pass-the-hash attacks.
1. Acquisition:
Hackers employ various strategies - social engineering, phishing and malware attacks - in this initial stage to attempt obtaining password hashes from either a domain controller or individual computers in this initial step. Once an attacker obtains hash data they can authenticate without actually needing their actual password to perform authentication.
2. Recovery:
Once they obtain the hash of the password, hackers use special tools to derive its actual contents - meaning no connection needs to exist between hacker and network user in order to retrieve password. This step may even occur offline!
3. Exploitation:
At this final step, an intruder gains access to resources like sensitive data, systems or applications by authenticating themselves on the network using stolen password and username information.
How does Cyberark protect against pass-the-hash attacks?
Cyberark offers an innovative solution that makes detection and prevention of pass-the-hash attacks simpler, particularly within organizations with multiple users and devices. Cyberark's protection can thwart these forms of threats effectively.
1.Cyberark's Password Vault:
Cyberark's password vault offers secure storage and rotation of privileged account credentials such as password hashes
for restricted accounts, thus restricting their usage by unauthorised parties and significantly complicating hacker attempts to obtain these hashes.
2. Just-in-Time Privileges:
Cyberark's Just-in-Time Privilege feature allows organizations to dynamically grant privileged access for limited and specific periods. In effect, password hashes would have an expiry timeframe before their usage became ineligible or could even become compromised and used by criminals.
3. Protection Against Credential Theft:
Cyberark's Endpoint Privilege Manager protects all privileged credentials on endpoints against theft - this means password hashes or any other credentials are inaccessible even to criminals gaining physical entry to user computers.
4. Advanced Monitoring and Alerting:
Cyberark solutions feature advanced monitoring and alerting capabilities that allow organizations to detect any suspicious activities quickly, prior to it leading to security compromise - this feature assists organizations with real-time detection of pass-the-hash attacks as well.
Organizations should take an aggressive stance towards protecting sensitive data and systems against pass-the-hash attacks in today's ever-evolving threat landscape, specifically in regard to pass-the-hash. Organizations can strengthen privileged account protection as well as mitigate credential theft through Cyberark's innovative solutions.
Because pass-the-hash attacks pose such serious threats, investing in comprehensive security solutions such as Cyberark is essential to protecting data and systems against future breaches. Not only does Cyberark provide protection from attacks; it also offers peace of mind by shielding sensitive systems against growing cyber security risks.
