Six of seven sources verified from disk snapshots. source-3.html.gz (gbhackers.com) returned HTTP 403 and could not be archived — however, all claims attributed to gbhackers.com are independently corroborated by the primary Kaspersky SecureList source (source-0). Verified: source-0.html.gz (Kaspersky SecureList): confirmed April 8 start date, versions 12.5.0.2421–12.5.0.2434, DTHelper/DiscSoftBusServiceLite/DTShellHlp.exe binary list, CRT environment quote verbatim, March 27 C2 domain registration, envchk.exe, QUIC RAT on educational institution in Russia, WolfSSL, notepad.exe/conhost.exe injection, 'chiper' misspelling, Chinese-language strings, 'do not currently attribute' quote, 100+ countries, Russia/Belarus/Thailand targeting. source-1.html.gz (BleepingComputer): confirmed attack timeframe. source-2.html.gz (HelpNetSecurity): confirmed attack narrative. source-4.html.gz (Daemon Tools blog): confirmed 'unauthorized interference within our infrastructure' quote, 07:00 GMT notification time, 12-hour response, version 12.6.0.2445, Ultra/Pro unaffected. source-5.html.gz (NVD): confirmed CWE-506, CVSS 3.1 score 9.8 CRITICAL, CVSS 4.0 score 9.3 CRITICAL. source-6.html.gz (SecurityWeek): confirmed 10% organizational systems figure.

All specific claims verified. The article correctly quotes Kaspersky verbatim throughout. The GBHackers-attributed claims (educational institution QUIC RAT recipient; 'chiper' misspelling) are independently confirmed in Kaspersky SecureList source. The version number discrepancy between the article (12.5.0.2421–12.5.0.2434) and the vendor blog (12.5.1) is a labeling difference, not a factual error — Kaspersky provides the precise build numbers.

Highly detailed, accurate cybersecurity article with strong sourcing across 7 outlets including the primary vendor and Kaspersky's research blog. Ready for publication.
