Key Insights from Japan’s Cyber Threat Landscape for CISOs

• Dark Web Activity Dominated by Data Sales: Most Japan-related underground posts involve selling stolen data, credentials, or sensitive assets.

• Data and Database Leaks Lead Threat Types: Stolen customer information, credentials, and corporate datasets make up the majority of dark web exposure.

• Access Listings Enable Direct Intrusion: A significant share of threats involve VPN access, internal panels, and compromised accounts sold to initial-access brokers.

• Qilin Drives Most Ransomware Incidents: Qilin remains the most active ransomware group targeting Japan, far surpassing other operators.

• Phishing Targets Banking & Crypto Users: JAネットバンク, Ethereum pages, and messaging platform lures are widely used to steal credentials.

• HTTPS Abuse Widens Phishing Risks: The vast majority of phishing pages use HTTPS, making malicious sites appear trustworthy.
