Phacking

Phacking is a term used in cybersecurity to describe the practice of using phishing techniques as part of a broader hacking operation to gain unauthorized access to accounts, data, or systems. The term is a portmanteau of phishing and hacking and is used in some communities to emphasize the criminal and technical aspects of credential theft. Not all sources distinguish phacking from phishing; some use phacking to denote phishing campaigns conducted as part of a larger intrusion.

Methods: Phacking typically involves social engineering combined with technical tricks. Common vectors include email phishing with credential harvesting pages, SMS or voice phishing (smishing and vishing), social media outreach, and fake apps or software updates. Attackers may use cloning or typosquatted domains, OAuth consent phishing, or embedded malware in attachments or links. Phishing kits and phishing-as-a-service platforms lower barriers for novice criminals and enable rapid deployment of campaigns.

Tactics and objectives: The goal is to harvest usernames and passwords, tokens, or other sensitive data, or to install malware to establish persistent access. Techniques include credential harvesting forms, MFA fatigue, credential stuffing, and indirect data exfiltration.

Defenses: Organizations promote awareness training, simulated phishing campaigns, and robust authentication practices such as multi-factor authentication and hardware keys. Email security with DMARC, DKIM, and SPF helps reduce spoofing. User education on red flags, such as unsolicited requests, urgent language, mismatched domains, and unfamiliar sender addresses, complements technical controls.

Legal and ethical considerations: Phacking is illegal in many jurisdictions and can violate computer misuse laws and data protection regulations; perpetrators face criminal charges, civil liability, and sanctions.
