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. Ransomware is a type of malicious software that locks users out of their system or data using different methods to force them to pay a ransom. Most often, such programs encrypt files on an infected machine and demand a fee to be paid in exchange for the decryption key. Additionally, such programs can be used to steal sensitive information from the compromised computer and even conduct DDoS attacks against affected organizations to pressure them into paying.
