Living Off The Land Detection

detecting-living-off-the-land-attacks

mukul975/Anthropic-Cybersecurity-Skills

Detects abuse of legitimate Windows binaries by tracking process creation, command-line parameters, and parent-child relationships to flag living-off-the-land and fileless attack patterns.

LOLBA Detection Playbook

detecting-living-off-the-land-with-lolbas

mukul975/Anthropic-Cybersecurity-Skills

Detect abuse of Living Off the Land binaries such as certutil, regsvr32, mshta, and rundll32 by ingesting Sysmon and Windows event telemetry, generating Sigma rules, and analyzing parent-child process chains to score alerts and report MITRE ATT&CK mappings.

Sysmon Scheduled Task Detection

detecting-malicious-scheduled-tasks-with-sysmon

mukul975/Anthropic-Cybersecurity-Skills

Detects malicious scheduled task creation and modification by correlating Sysmon IDs 1 and 11 with Windows Event 4698/4702, highlighting persistence hunting, suspicious parent processes, public paths, and encoded commands when tracking T1053.005 activity.

Mimikatz Execution Detection

detecting-mimikatz-execution-patterns

mukul975/Anthropic-Cybersecurity-Skills

Detect execution patterns of Mimikatz by correlating command-line signatures, LSASS access anomalies, binary indicators, and in-memory modules across EDR and SIEM telemetry, supporting proactive threat hunting and incident response.

Modbus Anomaly Detection

detecting-modbus-protocol-anomalies

mukul975/Anthropic-Cybersecurity-Skills

Detects Modbus/TCP and RTU anomalies by monitoring function codes, register ranges, timing, unauthorized clients, and malformed frames using Zeek, Suricata OT rules, and Python-based Markov models for deterministic industrial polling.

Zeek Network Anomaly Detection

detecting-network-anomalies-with-zeek

mukul975/Anthropic-Cybersecurity-Skills

Deploys Zeek to passively monitor network traffic, emit structured connection/DNS/HTTP/SSL logs, and run custom scripts that flag anomalous behavior for threat hunting and incident response teams.

IDS Network Scan Detection

detecting-network-scanning-with-ids-signatures

mukul975/Anthropic-Cybersecurity-Skills

Detect reconnaissance tools such as Nmap and Masscan using Suricata/Snort IDS signatures, thresholds, and anomaly cues to alert on TCP/UDP scans, SYN/ACK probes, and other scan fingerprints before threat actors escalate.

OAuth Token Theft Detection

detecting-oauth-token-theft

mukul975/Anthropic-Cybersecurity-Skills

Analyzes OAuth sign-in telemetry via Microsoft Graph and Okta APIs to spot impossible travel, new device patterns, token replay from unusual IPs, and anomalous scope requests, enabling early detection of access token theft.

Pass The Hash Detection

detecting-pass-the-hash-attacks

mukul975/Anthropic-Cybersecurity-Skills

Detecting Pass-the-Hash attacks by correlating NTLM Type 3 logons, telemetry from EDR/SIEM, and credential-dumping IOCs to proactively hunt and validate incidents across Windows estates.

Detecting Pass-The-Ticket

detecting-pass-the-ticket-attacks

mukul975/Anthropic-Cybersecurity-Skills

Analyze Windows Event IDs 4768, 4769, and 4771 within Splunk or Elastic SIEM to identify anomalous Kerberos ticket usage, RC4 downgrades, and unusual service requests, enabling proactive Pass-the-Ticket threat detection.

Privilege Escalation Detection

detecting-privilege-escalation-attempts

mukul975/Anthropic-Cybersecurity-Skills

Workflow for hunting privilege escalation attempts across Windows and Linux, leveraging EDR/SIEM telemetry to identify token manipulation, UAC bypasses, unquoted service paths, kernel exploits, and sudo/doas abuse.

Process Injection Detection

detecting-process-injection-techniques

mukul975/Anthropic-Cybersecurity-Skills

Detects malicious process injection techniques through memory forensics, Sysmon/API monitoring, and behavioral signals, aiding EDR/SIEM teams in spotting DLL injection, hollowing, APC/thread hijacking, reflective loading, and similar stealthy attacks.
