Snowflake-Related Arrests: UNC5537’s Kitchener Pinch
On October 30, 2024, Canadian authorities arrested a 26-year-old Kitchener, Ontario man on a US warrant connecting him to the Snowflake-account intrusions tracked by Mandiant as UNC5537 — the crew behind the Ticketmaster, Santander, and AT&T disclosures that dominated 2024’s data-theft calendar. The arrest, first reported in early November by Bloomberg identifying the suspect as Connor Riley Moucka, illuminated the infostealer-credential-to-cloud kill chain and the market for stolen data. This account reconstructs the campaign, the arrest, and the MFA lessons that outlast it.

CVE-2024-10924: Really Simple Security’s 2FA Betrayal
On November 6, 2024, Wordfence researcher István Márton disclosed CVE-2024-10924 — a CVSS 9.8 authentication bypass in Really Simple Security, the plugin securing four million WordPress sites, whose two-factor onboarding endpoint failed to validate the requesting user, granting attackers admin sessions on sites with incomplete 2FA enrollment. Patched same-day in 9.1.2, NVD-published November 14, the flaw became 2024’s definitive case study in security-plugin risk. This account walks the vulnerable code path, the four-million-site patch sprint, and why the ecosystem’s auth surface extends far past WordPress core.
