Cybersecurity Threats: ClickFix, Email Gateway Impersonation, and Citrix NetScaler

IBM Security Intelligence’s panel examines three current cyber threat stories and the defensive questions they raise. The discussion covers malicious links delivered through custom GPT pages, malware impersonating email security software, and exploitation of Citrix NetScaler vulnerabilities.

■ Threat techniques and detection
- ClickFix-style attacks promoted through sponsored search results and custom GPT pages
- Malware impersonating SpamSniper on email gateway systems, including monitoring outbound traffic and threat hunting
■ Vulnerability response and preparedness
- Citrix NetScaler exploitation, persistence checks, log retention, network segmentation, and incident response planning
- Information sharing, business continuity, and tabletop exercises

For security professionals and organizations responsible for internet-facing systems, the discussion offers practical priorities for investigation and response. It focuses on threat context and defensive planning rather than step-by-step configuration instructions.
