Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
Vulnerabilities exploited
3 CVEs Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
On March 12, 2026, the XLab Network-wide Threat Awareness System detected IP 107.150.106.14 spreading a VT 0-detection ELF sample implemented in C through the old vulnerabilities CVE-2013-3307 and CVE-2016-5681. The devices affected by these two vulnerabilities are several Linksys and D-Link router models from more than 10 years ago, respectively. | On April 26, we captured a homologous sample targeting NAS devices, spread through CVE-2025-11837. This sample is implemented in Go, and its source code path hints that the project name is Ary-Attack. Based on its behavioral characteristics and technical origins, we named this unknown virus family AryStinger.
