Executive Summary
Chinese-language, Telegram-based “guarantee� marketplaces are increasingly popular among Chinese-speaking criminal groups despite the widely publicized shutdown of Huione Guarantee in 2025. Although these guarantee marketplaces operate similarly to Huione Guarantee, they differ in their focus on particular aspects of cybercrime and in their targeting of specific geographies. To better understand these Chinese-language guarantee marketplaces, Insikt Group observed and analyzed another increasingly popular guarantee marketplace, dubbed Dabai Guarantee (“大白担��).
Given that guarantee marketplaces typically involve hundreds to thousands of public and private channels, this report outlines how Insikt Group analysts navigated through just one of the Telegram channels belonging to Dabai Guarantee’s large infrastructure. The channel is known as Dabai Guarantee Public Group 301 (@DBTM301), and its main objective is to conduct “sweeping� operations (using illicit techniques to make purchases of physical goods at retailers or to withdraw and transact at country-specific ATMs) in South Korea and Japan. This report also includes the visible organizational structure of Dabai Guarantee Public Group 301, key rules, staff, and customer service functions.
This report primarily serves as an introduction to understanding how Chinese-language, Telegram-based guarantee marketplaces work and how to navigate them. It also includes interpretations of multiple criminal terminologies used by Chinese-speaking criminals, which are pivotal to understanding how Chinese cybercrime evolves over time. The cyber and fraud campaigns being promoted and launched on Dabai Guarantee and other similar guarantee marketplaces can negatively impact retail, banking, contactless payment providers, insurance companies, and individuals vulnerable to scam-related campaigns.
Key Findings
- Dabai Guarantee is a platform that enables multiple Chinese-speaking threat groups with strong presences across multiple countries to coordinate and launch global-scale fraud and cyber campaigns.
- Chinese-speaking syndicates are using Dabai Guarantee as a platform to facilitate campaigns involving financial and retail fraud, such as ATM withdrawal and ghost-tapping.
- Criminal groups participating in campaigns are often siloed, acting independently, and restricting the sharing of information, resources, and goals, thereby creating barriers to tracking their activities.
- Unlike conventional ghost-tapping campaigns that mainly target luxury businesses, “sweeping teams� typically purchase goods that are less expensive but still considered valuable to criminal groups and are relatively easy to transport (such as women’s cosmetics and tobacco products), likely to avoid detection by law enforcement. The sweeping teams eventually resell them in other markets for cash.
- Dabai Guarantee’s bot search function makes it easy for Chinese-speaking criminals to enter specific search terms and be matched with existing public groups running those campaigns.
Background
Chinese-language guarantee marketplaces first emerged around 2021 with the launch of Huione Guarantee, serving as reliable alternatives to traditional dark web marketplaces accessible via the Tor network. Owners of traditional dark web marketplaces, such as Exchange Market and Chang’An Sleepless Night, have close to full control over advertisements and transactions. These guarantee marketplaces seek to eliminate distrust stemming from criminal groups scamming one another, dark web marketplaces shutting down, potential exit scams, and parties failing to honor terms that were previously agreed upon. Furthermore, guarantee marketplaces operate on publicly accessible Telegram channels by design; these public channels are meant to be found and appeal to a wider Chinese-speaking audience that uses Telegram, noting that most Chinese criminals still use Telegram rather than Tor for communication.
Guarantee marketplaces are often different from typical peer-to-peer (P2P) transactions between threat actors. Guarantee marketplaces are one-stop shops that handle and facilitate all cryptocurrency transactions (typically Tether/USDT) and mediation services between parties, whereas P2P transactions typically take place directly between users or through a third-party escrow service. The preferred cryptocurrency of Chinese-speaking threat actors is USDT, a stablecoin pegged to the US dollar that maintains anonymity. Stablecoins are a type of cryptocurrency designed to maintain a stable value by pegging themselves to reserve assets, most commonly the US dollar, to mitigate the volatility of cryptocurrencies like Bitcoin. According to Chainalysis’s 2026 Crypto Crime Report, stablecoins have come to dominate the landscape of illicit transactions, accounting for 84% of all illicit transaction volume in 2025. Chinese cybercriminals prefer using stablecoins such as USDT due to their combination of price stability, ease of border transfer, and relative anonymity. USDT also helps Chinese cybercriminals bypass China’s strict capital controls and traditional banking scrutiny to move money across borders.
In January 2025, Insikt Group published a report on the Chinese-language guarantee marketplace Huione Guarantee, “Huione Guarantee Serves as a One-Stop Shop for Chinese-Speaking Cybercriminals.� The report described the activities facilitated by Huione Guarantee, which include investment fraud, money laundering, and various online scams. Despite Huione Guarantee’s shutdown on May 13, 2025, Insikt Group observed that other guarantee marketplaces, such as Tudou and Xinbi, stepped in to fill the void left by Huione Guarantee's closure. According to Elliptic, Tudou Guarantee also shut down its operations in January 2026, after processing $12 billion in transactions. Even though Xinbi Guarantee was previously reported to have shut down, it has since been rebuilt and maintains a presence on Telegram as of this writing. Other, but not widely reported, active Chinese-language guarantee marketplaces operating on Telegram (besides Dabai Guarantee) are Yinuo, BoChuang, and Ouyi.
Guarantee marketplaces can also facilitate new attack vectors such as ghost-tapping. In July 2025, Insikt Group published a report titled “Ghost-Tapping and the Chinese Cybercriminal Retail Fraud Ecosystem,� which details how Chinese-speaking cybercriminals and syndicates work together to conduct retail fraud using near-field communications (NFC) relay tactics. As of February 2026, Insikt Group observed that Dabai Guarantee has emerged as a major player in Chinese-language cybercrime, with its Telegram-based infrastructure resembling that of Huione Guarantee and offering malicious services similar to those advertised on Huione Guarantee, which is now defunct.
Dabai Guarantee Overview
Dabai Guarantee is a Telegram-based marketplace, consisting of thousands of public and private Chinese-language Telegram groups, that operates in a manner similar to Huione, Tudou, and Xinbi guarantees; many of these services cater to “small to medium-sized clients.� However, the operators of Dabai Guarantee do not maintain a clearnet website; they operate solely on Telegram, likely due to operational security (OPSEC) concerns. Operators of Dabai Guarantee likely chose not to have a clearnet website in light of Huione’s “bad OPSEC� practices — Huione Guarantee’s clearnet website made tracking much easier for law enforcement officials and researchers, which likely contributed to FinCEN sanctioning the organization in May 2025. The Dabai platform is populated with third-party vendors providing various services that facilitate cybercriminal and fraud activities, including money laundering methods and services, compromised social media and e-commerce accounts, SIM cards, personally identifiable information (PII), malware-as-a-service (MaaS), deepfake technology, know-your-customer (KYC) bypass services, and more.
Dabai Guarantee was likely founded in December 2024, based on its Telegram Channel’s creation date. There are currently six known official main Telegram channels:
- “公群导航 @dabai� (@dabai_a): “Public Group for Navigation Purpose�, 15,372 subscribers, as of this writing
- “大白担�大群� (@dabai_c): “Dabai Guarantee Big Group�, 19,225 members, as of this writing
- “大白供需频�� (@dabaiyajing): “Dabai Supply and Demand Channel�, 17,085 subscribers, as of this writing
- “大白担�规则� (@dabai_e): “Dabai Guarantee rules�, 428 subscribers, as of this writing
- “大白担�客�人员��� (@dabai_f): “Dabai customer service list�, 527 subscribers, as of this writing
- “大白担� @dabai� (@dabai): “Dabai Guarantee bot channel�
Dabai Guarantee’s public navigation channel, 公群导航 @dabai, is used to direct threat actors to different private/public Telegram channels to coordinate and collaborate on campaigns targeting both Chinese-speaking and non-Chinese-speaking victims. Below is a list of the service categories offered on the public Telegram groups on Dabai Guarantee. Each category has subcategories for more specific services. Each public Telegram group has a unique group number, the amount of the deposit made to Dabai Guarantee in USDT, the handles of group administrators and customer service representatives, the transaction rules, and a dedicated cryptocurrency wallet. More information can be found in Figure 1. These specialized channels include the following:
- “海外钓鱼类� (“Overseas Phishing�) — Coordinate phishing campaigns against individuals residing outside of China
- “买�类� (“Trading�) — Buy and sell gift cards, databases, SIM cards, social media burner accounts, IP addresses, and physical goods
- “引�类� (“Traffic generation methods�) — Overseas SMS blasts, Baidu promotions, chat scripts, and other services
- “承兑类� (“Acceptance methods�) — Payment methods accepted by merchants include Alipay, WeChat Pay, and cryptocurrencies
- “通��作类� (“Cooperation Channels�) — Motorcade teams to conduct overseas operations such as collecting or making payments via cash and cryptocurrencies, and logistic operations to move physical goods
- “çŸè§†é¢‘ç±»â€� (“Short Videosâ€�) — Short Douyin videos for promotions
- “�作类� (“Cooperation�) — ID Loans, Apple IDs, courier delivery services, and burner mobile phones
- “�务类� (“Services�) — SMS verification, file lookup, and graphic design services
- “�商类� (“Carding Merchants�) — Money laundering through bank cards and contactless cash withdrawal without cards
- “æ�建类â€� (“Developersâ€�) — Software and bot setup services, and Apple signing/server/VPN/domain setup services
- “其他类� (“Others�) — Other miscellaneous fraud services, social escort services, police impersonation, artificial intelligence (AI), and search engine optimization (SEO)-related services
- “游�类公群� (“Gaming-related public groups�) — Online gambling and video games

Dabai Guarantee’s Rules (@dabai_e)
Dabai Guarantee’s rules channel (@dabai_e) has posted rules to prevent impersonation of the marketplace and to prevent users from creating their own “public groups� that are not officially regulated by Dabai Guarantee’s administrators. Some of the rules also showcase Dabai Guarantee’s OPSEC measures to prevent scamming and impersonation. The original Chinese text is in Appendix B. The following are some key rules:
- Members are not allowed to create their own public group channel without Dabai Guarantee`s approval.
- Members are not allowed to have private dealings with other parties or platforms, as Dabai Guarantee only guarantees transactions conducted on its platform. Dabai Guarantee also does not provide assurances for transactions with the Public Group “boss� or any other administrator. This means that no individual should have any transactions with the boss directly and should instead use Dabai Guarantee’s funds transfer mechanism.
- Individuals who initiate a chat session with you are 100% scammers; members are to block and refrain from chatting with them.
- The cryptocurrency address belonging to Dabai Guarantee is unique, and anyone sending other deposit addresses is a scammer.
- After members have staked their cryptocurrency as deposits, they are required to send Dabai Guarantee’s leadership screenshots of the deposit to @dabai for verification and confirmation. Any losses resulting from failure to contact @dabai will be the member’s responsibility.
Case Study: Public Group 301
Group Structure
For this report, we will use the Telegram channel “Public Group 301,� which belongs to Dabai Guarantee, as a case study. This is not meant to be a comprehensive analysis of Dabai Guarantee’s massive infrastructure and that of other Chinese-language guarantee marketplaces. It is difficult to accurately quantify how many “Public Group� channels and threat groups are on Dabai Guarantee, as the numbers tagged to Public Groups are not assigned in chronological order, resulting in a lack of visibility — unlike Huione Guarantee, which had a clearnet website that listed the Public Group channels to redirect threat actors. Although there are thousands of channels belonging to Dabai Guarantee alone, understanding Public Group 301’s structure can at least provide insight into how threat actors use Dabai Guarantee in their campaigns.
In guarantee marketplaces, threat actors looking to launch campaigns typically deposit USDT to start a public Telegram group approved by Dabai Guarantee. This model ensures that criminal syndicates do not have to deal with other threat actors directly, but have Dabai Guarantee as a mediator. In the case of Dabai Guarantee’s Public Group 301, affiliate threat groups do not have to engage directly with the group’s leader, @J0hnNo1, and instead receive payments from Dabai Guarantee after the completion of tasks required by @J0hnNo1. Guarantee marketplaces such as Huione, Tudou, Xinbi, and Dabai seek to eliminate the “lack of trust� among Chinese-speaking threat actors. These marketplaces are designed to become trusted platforms that foster coordination and cooperation between different Chinese-speaking criminal groups to achieve their objectives.
Insikt Group navigated through Public Group 301’s Telegram infrastructure in order to identify the redirection flow. As shown in Figure 1, each category contains a hyperlink that redirects to other channels. From Figure 1, selecting category 5, sub-category 2 (“海外扫货车队�, or “Overseas Goods Sweeping Team�) redirected to a pinned message as seen in Figure 2. This message lists four different public channels (“公群�) containing campaigns targeting the US, Canada, South Korea, and Japan.

As seen in Figure 2, “公群� refers to unique Public Group channels for specific purposes or operations. Each public channel here contains a numerical group identifier and a “U� deposit amount, where “U� refers to USDT. For example, “公群935已押2000U� refers to Public Group Number 935, with 2,000 USDT already being deposited in Dabai Guarantee to start the campaign. The naming convention for these Public Groups is �dbtmxxx�; in this case, Public Group Number 935 will have the Telegram channel @dbtm935. When selecting the second option, “公群301已押1000U韩国,日本扫货组�, which means Public Group Number 301, with 1,000 USDT already deposited to “sweep goods� in South Korea and Japan, the corresponding Telegram channel is @dbtm301.
Upon further investigation and analysis of the channel, Insikt Group assesses that “sweeping goods� refers to the use of illicit means, such as ghost-tapping, to purchase physical goods at physical retail stores (in this case, in South Korea and Japan). This activity also includes ATM cash withdrawals at Japanese or South Korean ATMs.
Key Personnel Involved in Public Group 301
The following terms are important for understanding the operations of criminals involved in Public Group 301, and the entire Dabai Guarantee infrastructure more broadly:
- Boss (“群���): The main coordinator overseeing a group’s operations. These individuals are not directly related to Dabai Guarantee and operate more like customers, making use of Dabai Guarantee’s infrastructure to lay out tasks and promising payouts in USDT upon completion. The boss will typically start a campaign by placing significant deposits into Dabai Guarantee’s USDT cryptocurrency addresses (“上押地��) in order to get Dabai Guarantee’s administrators to approve the creation of a Public Group channel. In Dabai Guarantee’s Public Group 301 (@dbtm301), @J0hnNo1 is the boss of the channel. We observed that this threat actor intends to conduct ghost-tapping and fraud campaigns in Japan and South Korea, with the key objective of obtaining physical goods, cash, and funds through unauthorized transactions. Once the boss confirms receipt of the items and is satisfied with the outcome, they can ask Dabai Guarantee to release the payment to the criminals who participated in the requested task.
- Channel Administrators (“管�员�): Dabai Guarantee’s personnel who act as intermediaries between the boss and other Chinese syndicates, ensuring that the boss gets the items and physical cash, while the Chinese syndicates are paid in USDT. These are the people who will process the payments. Channel administrators will also inspect video evidence provided by sweeping and “goods-receiving� teams and wait for confirmation from the boss that everything is satisfactory before releasing payments to the various Chinese-speaking criminal groups.
- Chinese Syndicates (“犯罪组织�): Teams in charge of providing the people (“mules�) to form sweeping and goods-receiving teams. These syndicates will coordinate with the boss and receive payment in USDT after completing the required jobs.
- Sweeping Teams (“扫货队�): Personnel tasked by the boss or other administrators with obtaining physical goods or conducting ATM cash withdrawals, typically through illegal methods such as ghost-tapping or financial fraud, and to eventually transfer the goods to “goods receiving� teams.
- Goods Receiving Teams (“收货队�): Personnel tasked by either the boss or their respective Chinese syndicates with receiving goods from sweeping teams; the items will eventually have to reach the “goods inspection teams.�
- Goods Inspection Teams (“检货队�): Personnel tasked with physically inspecting the goods and cash being delivered by the sweeping or goods-receiving teams, typically appointed by bosses. When the “goods receiving� team is appointed by the boss, it is also possible that the “goods receiving� and “goods inspection� teams are composed of the same personnel, each fulfilling multiple roles. These teams will inform the boss whether the physical goods are satisfactory, and the boss will proceed to ask Dabai Guarantee to release the payment to the sweeping and goods-receiving teams.
Insikt Group assesses that individuals in the sweeping, goods receiving, and goods inspection teams act as mules, and these teams likely consist of Chinese-speaking tourists who can amass large quantities of physical goods and cash and exit the targeted countries as soon as possible. It is also likely that Chinese-speaking groups have members who are long-term residents of the countries targeted by the operations, such as South Korea and Japan.

Figure 3 is a simplified illustration of Dabai Guarantee’s Public Group 301’s organizational structure. The barrier to entry for participating in “sweeping operations� is low, as participants just need to have the legal right to enter Japan or South Korea, pose as tourists, and follow the instructions given by the boss and other administrators. We estimate that there are likely more than a dozen sweeping teams linked to Dabai Guarantee operating in Japan and South Korea alone. Sweeping teams are likely assigned to obtain certain goods and cash in very specific areas and do not coordinate with one another because they are being deployed by different Chinese syndicates. This model suggests that operations are siloed, where teams act as independent, isolated units that restrict the sharing of information, resources, and goals.
Figure 4 shows the Telegram structure of Public Group 301, where @J0hnNo1 is the channel's boss. The channel is also composed of multiple Dabai Guarantee customer service staff, who serve as administrators. The original creator of the channel is @dbwb22; the Telegram account is no longer active, and @dbwb22 is no longer listed as one of Dabai Guarantee’s official customer service agents.

The distribution of these teams significantly complicates efforts by researchers and law enforcement agencies to track and deter such criminal activities. For example, if members of “Sweeping Team A� are arrested for retail or financial fraud, law enforcement agencies will still need to locate the members of the “Goods Receiving Teams� and “Goods Inspection Teams� before they can even get close to decoding the identity of the boss, who is most likely coordinating operations from a location outside Japan or South Korea’s jurisdiction, such as Cambodia or Myanmar. Additionally, these sweeping teams most likely consist of low-level mules who are considered “expendables� by their Chinese syndicate recruiters. The screenshots in Figures 6, 7, 8, 9, and 10 illustrate the siloed operations conducted by different sweeping teams.
Figure 5 shows Dabai Guarantee customer service personnel @dbtm9 helping to set up public Telegram channel 301 on March 21, 2025, and serving as the channel’s key administrator. This individual serves as a mediator to facilitate transactions and dealings between the boss and other threat actors. The total amount of USDT deposited on that date was 485 USDT; as of this writing, it has risen to 1,000 USDT. The purpose of this channel is to encourage other threat actors to cooperate by taking part in sweeping and goods-receiving operations in Japan and South Korea. In the conversation below, the boss stated that the deposit amount will increase in proportion to the transaction amount. Insikt Group assesses that this would mean the sum of deposit scales with the size of operations in Japan and South Korea.

Figure 6 shows that the boss is looking to recruit sweeping teams to conduct operations in Seoul, South Korea. The main objective is to purchase cosmetics, and once the goods have been delivered, the rewards will be “high.� The final sentence uses the term “速度快�, which means that the boss welcomes any sweeping team that can conduct and complete these operations quickly.

Figure 7 features a sweeping team involved in purchasing tobacco-related products from the Terea brand at a CU store, a South Korean convenience store chain in Seoul, South Korea. It is clear that the boss has goods from specific brands they wish to obtain, and such goods may be resold for cash in other foreign markets at a later date, likely at a lower price to obtain hard currency as soon as possible. Insikt Group assesses that the items are very likely purchased using the ghost-tapping attack vector or through stolen payment card information. This reflects a shift from targeting luxury retailers to smaller-sized businesses, likely to avoid arousing suspicion from law enforcement authorities

Figure 8 shows an Apple Store receipt listing unspecified Apple products totaling 499,600 yen (approximately $3,145.66, as of this writing). Public Group 301’s boss @J0hnNo1 also stated, “Who said there are no large transactions in Japan? Just a single receipt amounted to 500,000 Yen.� This is likely a post encouraging syndicates to send more sweeping teams to acquire as many Apple products as possible, while hinting that the rewards could be lucrative.

Figure 9 provides some evidence that Vietnamese individuals are also involved in sweeping operations. In the top-left corner of the iPhone in the image, the Vietnamese phrase "Không có SIM" means "No SIM card." This indicates that the person holding the phone is very likely a Vietnamese-speaking individual conducting unauthorized banking transactions using burner iPhones. Every single burner phone appears to be tagged with a label, which is very similar to the tactics, techniques, and procedures (TTPs) we documented in our Insikt Group report on ghost-tapping. It is also likely that this individual understands Japanese in addition to Chinese, as they were observed interacting with a Japanese banking application that displayed processed transactions. The transactions shown in the screenshot are dated between July 30, 2025, and August 28, 2025. The ability to use Japanese banking applications is an indicator that this individual is legally residing in Japan. In general, most Japanese banks require foreigners to close their bank accounts before leaving permanently; these regulations are implemented by major Japanese banks such as Shinsei Bank.

Figure 10 shows what appears to be an ATM cash withdrawal or transfer attempt at a Japanese ATM at an unspecified bank. This screenshot is also likely shown as an example of what sweeping teams in charge of withdrawing and transferring cash are expected and required to do.

Figure 11 shows a cryptocurrency transaction of 10,629 USDT via the Tron (TRX) network to a sweeping team for the successful completion of the “mission.� The boss @J0hnNo1 thanked the sweeping team coordinator without identifying them. The exact phrase used while posting the image was “感谢��信任�, which translates from Chinese to “Thank you boss for trusting me.� Boss, in this context, refers to the Chinese syndicates that provide the sweeping teams for successful operations. In the entire Dabai Guarantee Public Group 301 channel, there were many screenshots of such cryptocurrency transactions being sent to teams that participated in sweeping operations. The boss redacts recipients' cryptocurrency wallet addresses to prevent law enforcement agencies from tracking them. The TRON wallet address used by Public Group 301 is TByDzGWCirpCABaUorkhz5eWhjyDdYWgSo, as shown in Figure 11; this wallet address has facilitated a total of 2,943 transactions as of this writing.

Dabai Guarantee’s Staff and Customer Service Functions (@dabai_f)
Dabai Guarantee maintains a list of its official staff and customer service agents on its Telegram channel @dabai_f to facilitate the creation of Public Group channels and transactions. This system also helps prevent impersonation and scamming. Members are to contact customer service agents directly for any queries or concerns. The staff and customer service teams usually provide the functions listed in Tables 1 and 2; the customer service agents are listed in Figure 12 by their functions and Telegram handles.
This is to prevent impersonation, such as threat actors starting their own Public Group that is not officially approved by Dabai Guarantee.
There may be instances where Telegram deletes public channels for violating the terms of service, and the customer service team offers a service to restore them (This happened to Huione and Xinbi Guarantee; many of their channels were deleted by Telegram).
Customer service agents will attempt to resolve disputes between criminal groups when an unsatisfactory outcome is reached for one or more parties. They can also moderate disputes on transactions between buyers and sellers.
Resource matching refers to customer service agents attempting to match criminal groups to certain existing groups that are already participating in specific campaigns. In addition, customer service agents can connect buyers with sellers of goods and services.

Automated Bot System Directs Chinese Syndicates to Relevant Public Groups for Existing Campaigns
Insikt Group analyzed the public administrator bot @dbdbqg_bot to observe how a Dabai Guarantee user would be routed by the platform to participate in cybercriminal activities. To use this functionality, individuals must enter search terms in Mandarin. We used the terms 远程 (remote) and 数� (data), which returned three and ten public channels, respectively. When querying for the term “远程� (remote), which typically refers to ghost-tapping campaigns involving NFC relay methods, three Public Group channels appeared as relevant results. When querying for the term “数�� (data), which typically refers to databases, ten Public Group channels specializing in datasets appeared in the results. In addition, using a country as a search term, such as �国 (US), will also return results that show fraud or cyber campaigns targeting the US. This bot function demonstrates how easy it is for criminal groups to search for relevant groups, determine which campaigns they wish to participate in, and identify the types of datasets they are interested in procuring. Table 3 shows the number of Public Group channels involved in fraud or cyber campaigns for the search terms; specific details are not listed due to certain global entities named in the Public Group channels belonging to Dabai Guarantee.

Outlook
Even with guarantee marketplaces such as Huione Guarantee being shut down, many Chinese criminals are likely turning to these Telegram-based guarantee marketplaces to sell illicit goods and to offer their services. Guarantee marketplaces such as Dabai Guarantee have demonstrated their ability to coordinate operations in countries such as Japan, South Korea, Canada, and the US by using Chinese-speaking individuals who are traveling or residing in those geographies to conduct retail and financial fraud. Over time, Dabai Guarantee may be able to establish itself as a trusted escrow platform for Chinese syndicates to rely on, despite the growing competition from existing and new guarantee marketplaces. There is also a possibility that operators of other guarantee marketplaces could execute an exit scam, leading to a loss of trust in guarantee marketplaces as a whole among Chinese criminals.
Threat actors such as @J0hnNo1, the leader of Dabai Guarantee Public Group 301, seek to obtain physical goods and foreign currency through illegal means, giving specific instructions to different syndicates to complete their objectives. Such operations are scalable on demand and will become harder to track and disrupt over time due to the siloed nature of the sweeping and goods-receiving teams. This report showcases the activities and structure of a single group (Public Group 301), which is only one group among hundreds under Dabai Guarantee’s decentralized and growing infrastructure. Ghost-tapping and ATM withdrawals are commonly used by Chinese-speaking criminals for money laundering, and we will likely continue to see more threat actors facilitating such financial and retail-related crime on multiple guarantee marketplaces.
Insikt Group assesses that Chinese syndicates will continue to recruit and deploy non-Chinese individuals with specific language skills to participate in campaigns, as exemplified by the Vietnamese individual mentioned in Figure 9.
Insikt Group assesses that guarantee marketplaces have solidified themselves as a major alternative to traditional Chinese-language dark web marketplaces. This decentralized model is becoming increasingly popular among the global Chinese-speaking criminal diaspora, enabling criminals without sophisticated skillsets to coordinate with syndicates and participate in operations that require physical elements.
