T1110.002 / ATT&CK

Brute Force: Password Cracking

2 rules across 2 sources.

From MITRE ATT&CK 19.2

Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained. OS Credential Dumping can be used to obtain password hashes, this may only get an adversary so far when Pass the Hash is not an option. Further, adversaries may leverage Data from Configuration Repository in order to obtain hashed credentials for network devices.

Techniques to systematically guess the passwords used to compute hashes are available, or the adversary may use a pre-computed rainbow table to crack hashes. Cracking hashes is usually done on adversary-controlled systems outside of the target network. The resulting plaintext password resulting from a successfully cracked hash may be used to log into systems, resources, and services in which the account has access.

How MITRE says to detect it DET0105

Post-Credential Dump Password Cracking Detection via Suspicious File Access and Hash Analysis Tools

Windows Analytic 0292

Use of hash-cracking tools (e.g., John the Ripper, Hashcat) after credential dumping, combined with high CPU usage or GPU invocation via unsigned binaries accessing password hash files

  • WinEventLog:Sysmon EventCode=1
  • WinEventLog:Security EventCode=4663, 4670, 4656
  • WinEventLog:Sysmon EventCode=11
  • WinEventLog:Sysmon EventCode=10

Linux Analytic 0293

Execution of hash cracking binaries or scripts (e.g., john, hashcat) following access to shadow file or dumped hashes

  • auditd:SYSCALL execve
  • linux:syslog auth.log or custom tool logs

macOS Analytic 0294

Unsigned or scripting-based processes invoking password cracking binaries or accessing hashed credential artifacts post-login

  • macos:unifiedlog process and file events via log stream

Identity Provider Analytic 0295

Sudden valid logins from accounts that previously had credentials dumped but had not authenticated successfully in the past; correlated with timeline of suspected hash cracking

  • azure:signinlogs Success logs from high-risk accounts

Network Devices Analytic 0296

Offline cracking inferred by subsequent successful CLI or web-based authentications into routers or switches from previously dumped accounts

  • networkdevice:syslog config access, authentication logs
