| Verdict: | Malicious activity |
| Threats: | BlueSky ransomware, first identified in June 2022, shares code similarities with other well-known ransomware families like Conti and Babuk. It primarily spreads via phishing emails and malicious links and can propagate through networks using SMB protocols. BlueSky uses advanced evasion techniques, such as hiding its processes from debuggers via the NtSetInformationThread API, making it difficult for analysts to detect and mitigate its attacks. |
