This rule detects the execution of specific binaries identified as being used by the UNC4841 threat group to deploy the SEASPY backdoor. The binaries include 'BarracudaMailService', 'resize2fstab', and 'resize_reisertab'. Detection is based on the image path ending with any of these specific names.
An adversary may use legitimate desktop support and remote access software, such as Team Viewer, Go2Assist, LogMein, AmmyyAdmin, etc, to establish an interactive command and control channel to target systems within networks.
These services are commonly used as legitimate technical support software, and may be allowed by application control within a target environment.
Remote access tools like VNC, Ammyy, and Teamviewer are used frequently when compared with other legitimate software commonly used by adversaries. (Citation: Symantec Living off the Land)

This rule detects the presence of TargetCompany ransomware by identifying specific byte patterns associated with its core functionalities. These functionalities include encrypting files, generating encryption keys, finding files to encrypt, and establishing remote connections, which are all characteristic behaviors of ransomware.
This rule detects the Curator ransomware by identifying specific byte patterns associated with its file encryption routines, file discovery mechanisms, and remote connection capabilities. The rule looks for a combination of these patterns within a PE file, indicating the presence of the ransomware.
This Yara rule detects the Plague17 ransomware by identifying specific byte sequences associated with its file finding, file encryption, and remote connection functionalities. The rule looks for distinct patterns in the malware's code related to these core ransomware behaviors.
This YARA rule detects the Avaddon ransomware by identifying specific byte sequences related to its file finding, encryption, resource enumeration, and remote connection functionalities. The rule looks for a combination of these distinct patterns within a file, indicating the presence of Avaddon ransomware.
This rule detects the 5ss5c ransomware based on specific byte patterns found in its code. The patterns indicate functionality related to finding files, encrypting files, and establishing remote connections, which are characteristic behaviors of ransomware.
This rule detects the 'Good' ransomware by identifying specific byte patterns associated with its file finding, file encryption, and remote connection functionalities. The rule looks for a combination of these patterns within a PE file (indicated by the 'MZ' header).
This YARA rule detects the Ladon ransomware by identifying specific byte patterns associated with its file finding, file encryption, and remote connection functionalities. The rule looks for a combination of these patterns within a file to confirm the presence of Ladon ransomware.
