What technologies (VPNs, Tor, cryptocurrencies) keep carding operations anonymous and how effective are they?
Executive summary
VPNs, Tor and cryptocurrencies are repeatedly cited in reporting and research as tools carders use to obscure location and payment trails; for example, carding forums have long combined Tor-hidden marketplaces with cryptocurrency payments to protect participants’ anonymity [1] and “payments are made in cryptocurrency to avoid detection” on dark‑web forums [2]. But sources show important limits: Tor and VPNs can hide an IP address yet are imperfect and operational mistakes or law‑enforcement actions (seizures/arrests) have repeatedly unmasked operators and taken down markets [3] [4].
1. VPNs: cheap cloaks, imperfect shields
Many carding guides and underground forums recommend VPNs or list specific vendors as “best for carding,” arguing a VPN masks IPs and can bypass geolocation checks [5] [6]. Commercial privacy reviews also name mainstream VPNs for general anonymity and strong encryption [7]. At the same time, academic and law‑enforcement reporting warns that VPNs do not provide perfect anonymity: providers may keep logs, cooperate with authorities, or leak metadata, and forum users repeatedly debate trust in providers and logging policies [8] [9]. In short: VPNs can reduce straightforward attribution (IP → person) but are only as effective as the provider’s policies and the user’s operational security [7] [8].
2. Tor: strong network anonymisation, but not bulletproof
Tor’s onion‑routing makes it difficult for observers to link origin and destination, and researchers and security firms note Tor remains a powerful anonymity tool used by some carding forums and marketplaces [10] [11]. However, Tor does not guarantee perfect anonymity: the Tor Project itself says perfect anonymity is impossible and users can be deanonymised through mistakes, browser plugins, or operational security failures [3]. Law‑enforcement successes and academic analyses also show Tor‑hosted markets and forums have been identified and disrupted historically, demonstrating limits when adversaries target infrastructure or exploit human errors [12] [11].
3. Cryptocurrencies: convenient cashout with traceable trails
Multiple sources document that cryptocurrencies are commonly used for payments on carding markets and to launder proceeds because they avoid traditional bank KYC and permit rapid transfers [2] [13]. Dark‑web markets charged subscription fees in Bitcoin and used crypto for trades [1]. But crypto is not uniformly anonymous: chain analysis, exchange KYC and mixing failures have enabled law‑enforcement to trace flows and seize funds, and recent market seizures and arrests have reduced some marketplaces’ safety [4] [13]. Sources therefore characterize crypto as an operationally useful but technically traceable tool depending on how it is used [2] [4].
4. Operational practices matter more than any single tool
Researchers find carders combine multiple tools—VPNs, Tor, SOCKS proxies, virtual machines, RDP, MAC spoofing and crypto—to create “isolated setups” and layered OPSEC, and many tutorials stress operational hygiene [14] [15]. At the same time, recent reporting and seizures show law‑enforcement exploits market infrastructure, vendor reputations and transactional flows rather than simply tracing a lone IP; the fall of major markets (e.g., BidenCash seizure) and arrests illustrate this [4] [13]. Therefore, tool choice is necessary but not sufficient; human errors, vendor trust and cashout chains are frequent failure points [14] [4].
5. Two competing narratives in the sources
Security vendors and academic studies emphasize the technical limits and risks of anonymity tools—Tor offers strong protections but not perfection, and VPNs depend on logs/policy [3] [7]. Underground community posts and “how‑to” guides claim VPNs, SOCKS5 and specific providers are reliable for carding and give step‑by‑step OPSEC advice [16] [17]. Both views coexist in the record: defenders highlight structural weaknesses and law‑enforcement wins [4], while illicit‑scene materials assert practical effectiveness when used carefully [5] [15].
6. What the sources don’t say (limitations)
Available sources do not provide a quantified probability that a given configuration (e.g., VPN + Tor + mixer) will defeat law enforcement in 2025 — reporting documents patterns, arrests and market seizures but not a statistical “success rate” for anonymity techniques [4] [11]. They also do not list every technical deanonymisation method law enforcement may use; rather, they describe outcomes (seizures, arrests) and technical properties of the tools [3] [10].
7. Bottom line for readers and policymakers
Tor, VPNs and cryptocurrencies are effective at obscuring simple attribution and at enabling illicit marketplaces to operate, but the evidence shows they are not foolproof: operational mistakes, provider logs or cooperation, blockchain analysis, and coordinated law‑enforcement actions have repeatedly unmasked actors and dismantled markets [3] [4]. Policy responses and defense efforts therefore focus on disrupting cashout and market infrastructure as much as on technical tracing [4] [13].
