PartyWorld (Scam) – Malware

Overview

The PartyWorld scam has emerged as a significant threat targeting online gamers and cryptocurrency enthusiasts alike. Initially identified in June 2024 by Insikt Group, PartyWorld masquerades as a free-to-play “looter shooter” video game, similar to popular titles like Fortnite and Party Icon. The scam has gained traction through social media platforms, where it is marketed under the alias PartyWorldOGIX. However, beneath its seemingly innocent facade, PartyWorld is a vehicle for cryptocurrency scams and the delivery of infostealer malware. The game itself is a mere front, designed to lure victims into downloading malicious software that ultimately compromises their personal information and financial security.

At the heart of the PartyWorld scam is the Marko Polo cybercriminal group, which has been linked to several other notorious operations, including the previous Party Royale scam. Marko Polo operates with a well-established infection chain that begins with direct messages sent to potential victims on platforms like Discord and OpenSea. Scammers posing as human resources representatives offer seemingly legitimate job opportunities, with victims encouraged to download the PartyWorld game client. Once downloaded, the software installs malware that can steal sensitive data, including cryptocurrency wallets, personal information, and login credentials.

How they operate

A key element of this scam is its seamless integration with social media platforms and its ability to mimic legitimate game downloads. The campaign is powered by the Marko Polo threat group, a cybercriminal operation known for using various social engineering tactics to lure individuals into downloading malicious software. The process typically begins with the operators contacting potential victims on social platforms like Discord and OpenSea, where they impersonate legitimate recruiters offering job opportunities.

Once the victim engages with the scam, they are redirected to the PartyWorld website, where they are encouraged to download a game client. For Windows OS users, this client is delivered via a Dropbox link, which points to the executable file, PartyWorld.exe. The file is hosted on a Dropbox account, making it appear more legitimate and trustworthy to the victim. For MacOS users, the malware is distributed through a .dmg file, initially hosted on ask-ashika[.]com, and later moved to punitrai[.]com and rafaelsuarezlopez[.]com. The rapid shifting of hosting locations suggests that Marko Polo operators are actively working to evade detection and disrupt security monitoring efforts.

Once the victim downloads and installs the PartyWorld client, the malware silently executes in the background, starting the infostealer payload. This malicious component is designed to harvest sensitive information, such as cryptocurrency wallet credentials, personal details, and even banking information. The malware can be configured to collect and exfiltrate this data to remote servers controlled by the attackers. One key feature of the PartyWorld malware is its ability to communicate with external command-and-control (C2) servers, allowing the attackers to update the malware’s functionality, modify the data exfiltration process, and avoid detection by cybersecurity tools.

In addition to stealing sensitive data, the malware also often installs additional malicious modules. These can include components for cryptocurrency mining or for turning the victim’s machine into part of a botnet, which can be used to launch further attacks or steal more data from other victims. The malware is also capable of exploiting any vulnerabilities in the victim’s system, allowing it to persist even after attempts to remove it. This persistence is achieved through various techniques, such as modifying system settings and installing malicious drivers, making it difficult for the victim to manually uninstall the threat.

The infrastructure behind PartyWorld is equally sophisticated. Marko Polo operates bulletproof hosting services, which allow them to host their malicious domains and distribute malware with minimal risk of being taken down. These hosting services are used to maintain the ever-changing domain names and to keep the malware active even if one of the domains is blocked or flagged by security researchers. The shifting of hosting locations and the use of reputable services like Dropbox and private domains are deliberate tactics to bypass traditional security measures, such as domain blacklists and traffic analysis.

The rapid evolution of the PartyWorld infrastructure highlights the agility and persistence of the Marko Polo threat group. By constantly changing the domains used for downloading malicious software and keeping ahead of security measures, the operators can maximize their reach and continue infecting new victims. The group’s ability to exploit the popularity of online gaming and the cryptocurrency market makes this scam particularly dangerous, as it taps into two highly active and lucrative sectors, increasing the chances of success.

For cybersecurity professionals, the PartyWorld campaign serves as a reminder of how cybercriminals continue to innovate and evolve their techniques. The use of social media, gaming culture, and popular cryptocurrency trends to lure victims is a significant shift in the way malware is distributed. By understanding the technical aspects of how PartyWorld operates, users and organizations can better defend themselves against these types of threats. Implementing robust security measures, such as email filtering, malware scanners, and employee awareness programs, can help minimize the risk of falling victim to such sophisticated campaigns.
