PartyTicket Ransomware: In-Depth Analysis, Detection, and Mitigation
Summary of PartyTicket Ransomware
PartyTicket ransomware emerged in February 2022, as part of an initial wave of cyberattacks against Ukraine. The ransomware is associated with the deployment of HermeticWiper. The ransomware was used as a decoy / distraction during the distribution of HermeticWiper. The malware is written in Golang, with the code containing numerous references to the US government and Biden administration.
What Does PartyTicket Ransomware Target?
PartyTicket specifically targets Ukrainian organizations.
How Does PartyTicket Ransomware Spread?
PartyTicket is a decoy/distraction tactic. This threat was leveraged during the HermeticWiper attacks as a distraction from the greater cyber attacks occurring.
PartyTicket Ransomware Technical Details
PartyTicket is a Golang ransomware being used as a decoy alongside the deployment of HermeticWiper during attacks against Ukraine.
The purpose of PartyTicket is to monopolize resources of the “ransomware” when in fact the more destructive malware (wiper) is staged for launch.
In the case of PartyTicket, the main.subscribeNewPartyMember() function is indirectly called for each thread. It takes a filename, makes a copy named
The folder organization and function naming conventions within the binary show the developer’s intent for taunting the U.S. government and the Biden administration.
How to Detect PartyTicket Ransomware
- The SentinelOne Singularity XDR Platform can identify and stop any malicious activities and items related to PartyTicket.
In case you do not have SentinelOne deployed, detecting this ransomware requires a combination of technical and operational measures, which are designed to identify and flag suspicious activity on the network. This allows the organization to take appropriate action, and to prevent or mitigate the impact of the ransomware attack.
- Use antimalware software, or other security tools, which are capable of detecting and blocking known ransomware variants. These tools may use signatures, heuristics, or machine learning algorithms, to identify and block suspicious files or activities.
- Monitor network traffic, and look for indicators of compromise, such as unusual network traffic patterns, or communication with known command-and-control servers.
- Conduct regular security audits and assessments, to identify vulnerabilities in the network and the system, and to ensure that all security controls are in place and functioning properly.
- Educate and train employees on cybersecurity best practices, including how to identify and report suspicious emails, or other threats.
- Implement a robust backup and recovery plan, to ensure that the organization has a copy of its data, and can restore it in case of an attack.
How to Mitigate PartyTicket Ransomware
- The SentinelOne Singularity XDR Platform can return systems to their original state using either the Repair or Rollback feature.
In case you do not have SentinelOne deployed, there are several steps that organizations can take to mitigate the risk of ransomware attacks:
- Educate employees: Employees should be educated on the risks of ransomware, and on how to identify and avoid phishing emails, malicious attachments, and other threats. They should be encouraged to report suspicious emails or attachments, and to avoid opening them, or clicking on links or buttons in them.
- Implement strong passwords: Organizations should implement strong, unique passwords for all user accounts, and should regularly update and rotate these passwords. Passwords should be at least 8 characters long, and should include a combination of uppercase and lowercase letters, numbers, and special characters.
- Enable multi-factor authentication: Organizations should enable multi-factor authentication (MFA) for all user accounts, to provide an additional layer of security. This can be done through the use of mobile apps, such as Google Authenticator or Microsoft Authenticator, or through the use of physical tokens or smart cards.
- Update and patch systems: Organizations should regularly update and patch their systems, to fix any known vulnerabilities, and to prevent attackers from exploiting them. This includes updating the operating system, applications, and firmware on all devices, as well as disabling any unnecessary or unused services or protocols.
Implement backup and disaster recovery: Organizations should implement regular backup and disaster recovery (BDR) processes, to ensure that they can recover from ransomware attacks, or other disasters. This includes creating regular backups of all data and systems, and storing these backups in a secure, offsite location. The backups should be tested regularly, to ensure that they are working, and that they can be restored quickly and easily.

Party Ticket has been a part of the initial wave of Ukraine cyberattacks. It is commonly deployed with the Hermetic Wiper and associated with it.It acts as a decoy and distracts victims.
Party Ticket was first discovered in February 2022. It targeted mostly Ukrainian organizations back then.
It’s used in combination with Hermetic Wiper attacks and distracts victims from the greater cyberattacks that are incoming. It’s most commonly a distraction and decoy tactic that derails victims. It distributes malware by writing the code in Golang and containing numerous references to the U.S. government and the Biden administration.
Party Ticket mostly targets Windows devices and program files folders that are often skipped. It targets Windows devices and service folders that are often skipped. Party Ticket usually targets Windows devices and software files that stop usage. It targets Windows devices and program files folders that are often skipped. It mostly targets Windows devices and system files that are often skipped.
This ransomware’s main goal is to lock your files and force you to pay money to unlock them. Criminals hope you’ll get desperate enough to pay a ransom, thinking it’s the fastest way to get back to business. You can stand against these tactics by having good backups offline, so you aren’t totally stuck if they scramble your data. Once you’re prepared, PartyTicket’s big plan doesn’t look so scary.
PartyTicket is mostly created in C++, a common language for making powerful but sneaky malware. C++ allows attackers to add tricks that hide their code and mess with your system’s defenses. If you keep your operating system updated, you lessen the chance of letting this type of malware run wild. You can also watch security news sites for any fresh details on PartyTicket’s coding style.
PartyTicket usually uses a blend of standard encryption techniques like AES to scramble your files and RSA to handle the special keys. AES locks your stuff tight, while RSA can protect the secret code needed to unlock it. These methods are tough to crack on your own.
The targeted file will be renamed with an extension, and the malware will embed a hard-coded 2048-bit RSA key that is Base64-encoded. Once files are encrypted, the malware will delete the temporary copy of the ransomware. A ransom note will be written on the user’s desktop with the filename readme.html.
Regularly patch your systems and scan for threats. Check emails closely for odd addresses or messages pushing you to act fast. Turn on multi-step logins where you can, and never share your password with anyone. You can also split your network into sections, so PartyTicket has a harder time spreading. Following these steps creates more roadblocks for hackers, making them work harder or give up altogether.
Yes. EDR tools keep an eye on your device’s behavior and can raise the alarm when they spot weird patterns, like a program locking loads of files at once. They can halt the ransomware before it takes control. However, EDR alone isn’t a perfect fix. You can get better results by backing it up with well-trained users, strong passwords, and frequent software updates to block PartyTicket’s tricks.
