# Sandworm Exposes Ukraine Cybersecurity Gaps

ESET reported that Russia-aligned Sandworm operators maintained access to a Ukrainian grain logistics company for 63 days using the MythicRatatoskr backdoor and the decentralized Yggdrasil mesh network, then wiped domain-joined systems with Microsoft SDelete. The incident shows how attackers can evade defenses based mainly on domain and IP blocking and highlights cybersecurity capabilities relevant to government agencies and contractors supporting logistics and other critical supply chains. The signal identifies no specific solicitation, contract, or procurement opportunity.

- Agencies and contractors supporting logistics operations can use the incident to assess whether their defenses include behavioral endpoint monitoring, network egress controls, and Active Directory change monitoring.
- Resilient offline backups are a relevant safeguard against destructive attacks that wipe domain-joined systems.
- For cybersecurity providers, the incident points to demand for these defensive capabilities, but does not identify a funded requirement or active buying opportunity.
