Insights from the CrowdSec network reveal that the attackers trying to exploit CVE-2020-8656 are composed of a fairly even mix of opportunistic and targeted actors. Some attackers employ preliminary reconnaissance, while others use indiscriminate scanning. In addition, according to the CrowdSec network, attack volume against CVE-2020-8656 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.
