    El FBI incautó siete dominios de Flax Typhoon y siete países publicaron un aviso conjunto sobre Integrity Tech, la empresa china ligada al grupo: escanean con MicroScan (más de 1.300 scripts) y entran por ocho CVE viejas. Cinco entraron al KEV el 8, con plazo el domingo 11. Las ocho que más usan, según el aviso (vía BleepingComputer y The Hacker News): • ProFTPD CVE-2015-3306 • ISC BIND CVE-2015-5477 • Apache Struts CVE-2016-3081 • ONLYOFFICE Docs CVE-2021-3199 • Strapi CVE-2023-22894 • Bash (Shellshock) CVE-2014-6278 • Pulse Secure (Ivanti) CVE-2019-11510 • GitLab CVE-2021-22205 Las cinco primeras entraron al KEV el 8 de octubre; las otras tres ya estaban. Además: password spraying contra Exchange con la herramienta EBurst, robo de correos y de credenciales de Active Directory, SoftEther VPN para quedarse adentro y hasta un portal web para que terceros leyeran los correos robados sin entrar a las cuentas. Entre los dominios incautados están c0cc[.]cc (acceso a MicroScan) y outlook3650[.]com y linkedinns[.]net (entrega de malware de FishHub). Qué hacer: buscar esas ocho CVE en lo que tienes expuesto a internet (sí, cosas de 2015 siguen vivas), apagar servicios que nadie usa, exigir MFA en Exchange y Microsoft 365 y cruzar los indicadores del aviso con tus logs.
