Questions behind the headlines

These dated reading prompts are separate from the automatically refreshed headlines above.

What does “we patched it” leave unanswered?

The PHP notice is a useful starting point for thinking beyond a version number. The NCSC calls for finding affected systems, applying vendor updates, and considering whether an exposed system may already have been compromised. For discussion: how would you know where a shared software component is running, and what evidence would make you confident recovery is complete?

When forgotten software still trusts someone

Eye Research’s account of an abandoned Time4Popcorn updater connects software maintenance with trust. The application could be forgotten while its updater kept working in the background. For discussion: when a project ends or a domain changes hands, who should retire the connections and permissions it leaves behind? The researchers’ intervention also raises questions about responsibility and consent.

Sources & collection

Public RSS, Atom, and the CISA KEV JSON catalog are fetched by SecSIG’s server. Your browser requests only this site’s generated data. Each feed retains up to 30 headlines from the past year; quiet researchers may have older posts. KEV retains up to 300 entries added within 90 days. Publication, source update, first collected, and catalog-added dates have different meanings and are labelled separately.

A failed source keeps its last good headlines and last-success timestamp. Topic labels are approximate. The inventory includes source languages; headlines are not translated. New visitors start with all sources and topics selected. Your preferences also apply to topic archives.

Preferences use one optional first-party cookie for about six months: source-selection bits, topic-selection bits, and a format version. It contains no identity or tracking identifier. You can use filters without remembering them, change your choices, or reset them at any time. Without JavaScript, all-source headlines and paginated topic archives remain available.
