Password from successful login to the infected server: Whenever someone logs in a system infected with Linux/Ebury, the sshd daemon will save the password and send it to the exfiltration server. Password on successful login from the infected server: When someone uses the ssh client on an infected server, Linux/Ebury will intercept the password and sent it to its exfiltration server. Private key passphrase: When the ssh client on an infected server prompts the user for an private key passphrase, the passphrase will be sent to the remote exfiltration server. Unencrypted private key: When a private key is used to authenticate to a remote server, the unencrypted version is intercepted by the malware. Unlike passwords, it will not send the key to the exfiltration server. Instead, it will store it memory and wait for the operators to fetch the key with the Xcat command. Private keys added to the OpenSSH agent with ssh-add: The keys added to an OpenSSH agent are also intercepted by the malware. Both the unencrypted key itself and the passphrase typed by the user will be logged
