Enfour publishes its signed breach advisories on the FrontierStack website

Leak news, the advisories FrontierStack and KeyRotate receive when a service or server software their users rely on is breached, is now on frontierstack.app in English, Japanese and Korean.

Enfour, Inc. today made Leak news part of the FrontierStack website. Leak news lists the breach advisories Enfour sends to its FrontierStack and KeyRotate apps: what happened at the affected company, which keys and logins are most likely to be at risk, and the steps to take. Until now the list was published only on KeyRotate's site. It is free to read, and needs no account.

Where the advisories come from

Enfour's Security Watch service reads nearly 50 sources around the clock in English, Japanese and Korean. They include national computer emergency response teams (CISA in the United States, CERT-EU and ENISA in the European Union, JPCERT/CC, IPA and JVN in Japan, and KrCERT/CC and KISA in Korea), lists of vulnerabilities known to be exploited, software projects' own security announcements and the security press. It keeps only incidents that can reach people who use FrontierStack or KeyRotate. A person reads and checks every advisory before it is signed and sent.

What readers see

• A severity rating from one to three fires. Three means keys or logins were, or may have been, taken.
• Breaking advisories, the most severe ones from the last 72 hours or not yet contained, are marked and listed first.
• A signature check. Every advisory is signed with Enfour's key, and the page checks the signature in the reader's browser before it shows a newer list than the one it was built with.
• An archive. Thirty days after an incident's last date, its advisory moves to a searchable archive.

In the apps

FrontierStack compares each advisory with the domains and servers a person manages and raises a Security alert only when one of them is affected. The steps stay as a checklist until the advisory is marked dealt with. Where an incident exposed API keys, KeyRotate replaces those keys everywhere they are used.
