You are urgently contacted by Alice-Corp, a company specialized in developing technological solutions. Our server as well as all workstations connected to our Active Directory have suddenly been encrypted. The Alice-Corp network team managed to capture part of the network traffic. As a forensic investigator, you must analyze this file to find:

The email address used by the attacker (format: attacker@example.com) The email address targeted within the company (format: victim@alice.corp) The MD5 hash of the first malware The domain name contacted to download a script The password used to connect to the server The name of the scheduled task that was executed The domain name (in lowercase) contacted by the script to download the second malware The MD5 hash of the malware present on the server The domain name used for data exfiltration The name of the ransomware gang (in lowercase) The cryptocurrency wallet address used by the attackers The final flag contained in a file exfiltrated by the malware Then create a sha256 digest. example echo -n "totor@example.com:roro@alice.corp:5d41402abc4b2a76b9719d911017c592:example.com:123456789:ImAtask:example.com:5d41402abc4b2a76b9719d911017c592:example.com:black-cat:84EgZVjXKF4d1JkEhZSxm4LQQEx64AvqQEwkvWPtHEb5JMrB1Y86y1vCPSCiXsKzbfS9x8vCpx3gVgPaHCpobPYqQzANTnC:fin4l_flag" | sha256sum
