ShadowV2 Botnet Activity Quietly Intensified During AWS Outage

The recently discovered wave of malicious activity has raised fresh concerns for cybersecurity analysts, who claim that ShadowV2 – a fast-evolving strain of malware that is quietly assembling a global network of compromised devices – is quietly causing alarm. It appears that the operation is based heavily upon Mirai’s source code and is much more deliberate and calculated than previous variants. The operation is spread across more than 20 countries. 

Moreover, ShadowV2 has been determined to have been created by actors exploiting widespread misconfigurations in everyday Internet of Things hardware. This is an increasingly common weakness in modern digital ecosystems and it is aimed at building a resilient, stealthy, and scaleable botnet. The campaign was discovered by FortiGuard Labs during the Amazon Web Services disruption in late October, which the operators appeared to have been using to cover up their activity. 

During the outage, the malware spiked in activity, an activity investigators interpret to be the result of a controlled test run rather than an opportunistic attack, according to the report. During its analysis of devices from DDWRT (CVE-2009-2765), D-Link (CVE-2020-25506, CVE-2022-37055, CVE-2024-10914, CVE-2024-10915), DigiEver (CVE-2023-52163), TBK (CVE-2024-3721), TP-Link (CVE-2024-53375), and DigiEver (CVE-2024-53375), ShadowV2 was observed exploiting a wide range of CVE-2024-53375.
