Ongoing exploitation of Cisco Catalyst SD-WAN vulnerabilities

Cisco Talos tracks active exploitation of CVE-2026-20182, an authentication bypass vulnerability in Cisco Catalyst SD-WAN Controller and Manager, allowing remote attackers to obtain administrative privileges. The exploitation is attributed to UAT-8616, a sophisticated threat actor previously involved in similar attacks. Additionally, multiple threat clusters have been exploiting CVE-2026-20133, CVE-2026-20128, and CVE-2026-20122 since March 2026, following public release of proof-of-concept code by ZeroZenX Labs. Post-compromise activities include deployment of various webshells, including XenShell, Godzilla, and Behinder variants, along with cryptocurrency miners, red team frameworks like Sliver and AdaptixC2, and credential stealers. Ten distinct threat clusters have been identified, each utilizing different malicious tooling and infrastructure. Affected systems require immediate patching and security measures.

New blog post!

This time I talk about my new favorite evasive shellcode loader, Charon. I give a brief overview about what it does, how it works and which techniques it uses.

Also a brief addendum for enjoyers of bloated Implants such as Sliver.

«Ждите гостей»: новые инструменты и тактики PhantomCore в атаках на российские компании

На примере новой атаки PhantomCore - одной из главных киберугроз для российских и белорусских компаний - показываем, как группировка развивает свои инструменты и тактики, внедряет новое ВПО и расширяет спектр используемых технологий, включая AI-решения. Одна из главных особенностей PhantomCore – её постоянная изменчивость: эта АРТ-группа быстро приспосабливается к новым условиям, оперативно меняет инструменты и изобретает нестандартные способы доставки ВПО до атакуемых организаций.
