opsecosint.info

What it is. A structured 10-chapter reference guide for the OpSec and OSINT concerns that hit crypto users specifically — wallets, threat modelling, blockchain analysis, phishing, wallet-drain mechanics, SIM-swap, doxxing, physical threats. Ten chapters split evenly between OpSec (five) and OSINT (five), plus an interactive quiz surface. Cross-crypto by scope; not Monero-exclusive, but the threat-model set is the one a privacy-minded Monero user needs to internalise anyway.

Author. Published by `@CR1337` on X (verified handle) on 2026-07-08. CR1337 is not new to the Monero ecosystem — also runs Monero.Jobs (privacy-first freelance marketplace paid in XMR), wtfisxmr.lol (beginner explainer), and the original XMR 1337 Guide, plus paid partnership content on X. See the maintainer profile at `/who/cr1337` for the full portfolio. The grade below reflects opsecosint.info the site, not the author's broader track record.

What you trust. The guide's editorial choices are clean: honest threat-model framing (*"threat model first"*), a *"verify, then trust"* chapter, an explicit *"plan for failure"* chapter, and an "OpSec habits and maintenance" chapter that pushes the guide past one-off reading into a habit-formation shape. The quizzes double as a comprehension-check surface. What you don't get: a professional peer-review process visible on the site, versioned change history, or a public roadmap.

Grade B (not A). The two other reference guides on xmr.club at this subcategory (Privacy Guides, EFF-SSD) sit at Grade A because of years of content tenure — public commit history, dated revisions, an audit trail readers can follow to verify the guide hasn't quietly drifted. opsecosint.info is a brand-new site with an unproven maintenance cadence, no exposed change log, and a Lovable portability caveat (see below). CR1337's ecosystem track record via Monero.Jobs, wtf-is-xmr, and the XMR 1337 Guide is real, but our grade rubric weights the *content* not the *author* — so a fresh site starts where its own content-tenure starts, at B. Grade lifts on 90 days of visible maintenance cadence (dated chapter revisions or a public change log) or a migration to a portable host with an inspectable history.

Caveats.

• Hosted on Lovable with a custom `.info` domain — the site is fully dependent on the author's Lovable subscription + DNS delegation staying live. Portability is not proven.
• Cross-crypto rather than Monero-specific — the threat models apply, but readers looking for XMR-specific tradecraft still need to reach for Monero-native references separately.
• No exposed change log or version history at time of listing. If you want to know whether a chapter was rewritten between reads, you have to check yourself.
