Incident Network Traffic Analysis

analyzing-network-traffic-for-incidents

mukul975/Anthropic-Cybersecurity-Skills

Examines packet captures, Zeek logs, and NetFlow data to uncover C2 channels, lateral movement, and exfiltration during security incidents, guiding analysts through capture, filtering, and IOC extraction workflows.

Ransomware Network Indicators

analyzing-ransomware-network-indicators

mukul975/Anthropic-Cybersecurity-Skills

Analyze Zeek conn.log and NetFlow data to surface ransomware network indicators such as C2 beaconing, TOR exit node connections, high-volume exfiltration flows, and risky DNS patterns, then score risks for incident response and detection tuning.

Full-Scope Red Teaming

conducting-full-scope-red-team-engagement

mukul975/Anthropic-Cybersecurity-Skills

Guides planning and executing MITRE ATT&CK-aligned red team engagements from reconnaissance through reporting, emphasizing stealthy payloads, lateral movement, defined objectives like domain dominance and data exfiltration, and the legal/prerequisite controls needed to validate detection and response readiness.

DNS Query Exfiltration Detection

detecting-dns-exfiltration-with-dns-query-analysis

mukul975/Anthropic-Cybersecurity-Skills

Builds a passive DNS analysis pipeline that flags DNS tunneling attempts by inspecting query entropy, subdomain length, volume spikes, TXT abuses, and response payload sizes so SOCs can detect exfiltrating data hidden in DNS traffic.

Detecting S3 Exfiltration

detecting-s3-data-exfiltration-attempts

mukul975/Anthropic-Cybersecurity-Skills

Detects unauthorized S3 mass downloads by correlating CloudTrail S3 events, GuardDuty findings, Macie alerts, and VPC logs, enabling security teams to spot cross-account transfers and respond swiftly.

AgentTesla Config Extractor

extracting-config-from-agent-tesla-rat

mukul975/Anthropic-Cybersecurity-Skills

Extract embedded Agent Tesla RAT configuration such as SMTP/FTP/Telegram exfiltration credentials, keylogger settings, and C2 data from .NET assemblies via dnSpy/ILSpy decompilation and memory analysis for malware research or red-team validation.

Zeek DNS Tunnel Detection

hunting-for-dns-tunneling-with-zeek

mukul975/Anthropic-Cybersecurity-Skills

Analyze Zeek dns.log for long queries, high-entropy subdomains, unusual record types, and query volumes to detect DNS tunneling and covert data exfiltration before it reaches other channels.

Content Security Policy Bypass

performing-content-security-policy-bypass

mukul975/Anthropic-Cybersecurity-Skills

Analyzes Content Security Policy implementations and demonstrates bypass techniques such as unsafe directives, JSONP gadgets, nonce leaks, base-uri and form-action tricks to enable XSS execution and sensitive data exfiltration during security assessments.

Network Packet Forensics

performing-network-packet-capture-analysis

mukul975/Anthropic-Cybersecurity-Skills

Use Wireshark, tshark, tcpdump, and Python tooling to inspect PCAP/PCAPNG data, reconstruct communications, surface malicious traffic, and support incident investigations with evidence of exfiltration or C2 activity.

Cloud Log Forensics Athena

performing-cloud-log-forensics-with-athena

mukul975/Anthropic-Cybersecurity-Skills

Uses AWS Athena to define forensic tables and run queries against CloudTrail, VPC Flow, S3 access, and ALB logs, helping security teams detect unauthorized access, data exfiltration, lateral movement, and privilege escalation during incident investigations.
