Risky Bulletin
Catalin Cimpanu, Risky Business Media
The densest free security news digest: around a hundred items three times a week across breaches, cybercrime arrests, threat intel, malware, APTs, and policy, each with a source link. For CTI readers; not OSINT tradecraft.
Formerly Risky Business News, now on a self-hosted Ghost site, Risky Bulletin opens with one analysed story and follows with sectioned link lists: breaches and incidents, tech and privacy, government and policy, arrests and threat intel, malware reports, APTs and info-ops, vulnerabilities, and industry. A weekly companion, Seriously Risky Business, adds analysis. Sponsor-supported and free.
Worth it if
- You work in threat intelligence or a SOC and need the week's cybercrime and APT news in one place
- You investigate breaches and want arrests, leaks, and attributions as they happen
- You prefer links to source material over commentary
Skip it if
- You want OSINT technique, geolocation, or investigative method; there is none
- You find a hundred items a day overwhelming

Questions, answered
Is this an OSINT newsletter?
No. It is security news that OSINT and CTI analysts rely on for context. It teaches no technique.
Is there a paid tier?
None observed. It is free and sponsor-supported, with sponsored segments marked in each issue.
