New research shows 55% of cases involve American victims

SURREY, England — In an eye-opening study that sheds new light on the evolving landscape of digital financial crime, researchers have uncovered a striking pattern in Nigerian cryptocurrency fraud: all convicted perpetrators are male, and nearly two-thirds are under 30 years old. This revelation comes from recent research conducted through an unprecedented collaboration between academic institutions and Nigeria’s Economic and Financial Crimes Commission (EFCC).

The study arrives at a critical moment in global digital finance. Nigeria has emerged as the third-largest player in Bitcoin transactions globally, trailing only Russia and the United States, with cryptocurrency transactions reaching approximately $400 million. This surge in digital currency adoption reflects both opportunity and risk in Africa’s most populous nation, where only 36.8% of adults have access to traditional banking services.

“Our research reveals a disturbing surge in cryptocurrency fraud,” says study lead author Dr. Suleman Lazarus, a cybercrime expert at the University of Surrey, in a statement. “We’re observing a rising generation of young, tech-savvy male offenders who adeptly exploit digital platforms and cryptocurrencies to perpetrate high-stakes fraud.”

The research, published in Current Issues in Criminal Justice, reveals a clear geographical targeting pattern, with 55% of cases involving American victims. This international reach demonstrates how digital currencies have transformed the scope and scale of financial crimes, enabling fraudsters to operate across borders with unprecedented ease.

What makes these findings particularly intriguing is the fraudsters’ educational background. Despite the technical nature of cryptocurrency transactions, only a quarter of convicted fraudsters held university degrees, challenging assumptions about the expertise required for such crimes.

The digital toolbox of these fraudsters primarily consists of mainstream social media platforms. Facebook emerged as the preferred platform, used in 27% of cases, followed by Gmail at 22% and Instagram at 14%. These familiar platforms serve as hunting grounds where fraudsters establish trust before executing their schemes.

The financial scale of these operations is staggering. While some cases involved modest sums around $1,000, others reached heights of $475,000 in cash, with one case involving 1,200 Bitcoin – approximately $81.96 million. These figures underscore the lucrative nature of cryptocurrency fraud and its potential for devastating financial impact.

Bitcoin dominates as the preferred cryptocurrency for fraudulent activities, featuring in 46% of cases. This preference likely stems from Bitcoin’s decentralized nature and the relative anonymity it provides, presenting significant challenges for law enforcement in tracking and recovering stolen funds.

“As cryptocurrencies continue to gain popularity, our research serves as a wake-up call for law enforcement agencies, policymakers, and the general public to remain vigilant against the evolving threats in the digital financial landscape,” warns Dr. Lazarus.

The study illustrates how Nigerian cybercrime has evolved from traditional advance-fee scams to sophisticated cryptocurrency operations, reflecting broader changes in global financial systems and highlighting criminal enterprises’ adaptability. In a digital age where cryptocurrency promises financial inclusion and opportunity, this research serves as a crucial reminder of the shadow economy emerging alongside legitimate digital finance.

Paper Summary

Methodology

The study employed a structured approach, examining court records and case files of convicted cryptocurrency fraudsters from two major EFCC commands in Nigeria. Researchers analyzed 22 cases, documenting the fraudsters’ methods, preferred platforms, victim locations, and financial gains. This approach provided verifiable data from official sources, though it necessarily focused only on cases that resulted in convictions.

Results

The findings paint a clear picture: all convicted fraudsters were male, predominantly under 30, with relatively low formal education levels. They primarily used social media platforms, with Facebook being the most common tool. Most targeted American victims, using Bitcoin as their preferred cryptocurrency. Financial gains varied significantly, demonstrating the range of schemes employed.

Limitations

The research faced several constraints. The sample size of 22 cases, while providing valuable insights, represents only convicted cases, potentially missing more sophisticated operators who evade detection. Additionally, the focus on two EFCC commands might not represent the entire country’s cryptocurrency fraud landscape.

Discussion and Takeaways

The research reveals an urgent need for international collaboration in combating cryptocurrency fraud. The predominance of young male offenders and their focus on American targets suggests a need for targeted intervention strategies and enhanced cross-border cooperation in law enforcement.

Funding and Disclosures

The study, conducted in collaboration with Nigeria’s EFCC, underwent ethical clearance from both the University of Portsmouth (clearance number 1110) and the EFCC. The research team reports no conflicts of interest, with one author’s EFCC employment providing valuable access to case files while maintaining ethical research standards.

North Korean hackers allegedly stole record .02 billion of cryptocurrency in 2025. Here’s how they did it | Stock Market News

North Korea remains dominant threat to cryptocurrency security in 2025, even while confirmed incidents have decreased, according to a report by blockchain analytics company Chainanlysis.

Hackers from the Democratic People’s Republic of Korea (DPRK) allegedly stole a record $2.02 billion of crypto this year — a 51% jump compared to 2024, and taking their all-time total to $6.75 billion, it added.

The analysis further found that the DRPK is achieving larger thefts with fewer incidents, using unique methods to gain access and pull off their heists.

North Korea’s alleged crypto heists: Here’s how they did it

As per the report, these hacks were often carried out in unique fashion by embedding IT workers inside crypto services or using sophisticated impersonation tactics targeting executives.

Embedding IT workers

This is among the DPRK’s “principal attack vectors”, the report said. It added that the hackers secured jobs inside crypto services to gain privileged access and enable high‑impact compromises.

“Part of this record year likely reflects an expanded reliance on IT worker infiltration at exchanges, custodians, and web3 firms, which can accelerate initial access and lateral movement ahead of large‑scale theft,” it noted.

Fake jobs

Further, taking the IT worker model and “flipping it on its head”, the analysis said that DPRK-linked operators are also increasingly impersonating recruiters for prominent web3 and AI firms. This way, they orchestrate fake hiring processes that culminate in “technical screens” designed to harvest credentials, source code, and VPN or SSO access to the victim’s current employer.

“At the executive level, a similar social‑engineering playbook appears in the form of bogus outreach from purported strategic investors or acquirers, who use pitch meetings and pseudo–due diligence to probe for sensitive systems information and potential access paths into high‑value infrastructure,” it added.

Higher- value attacks

Over the years, DPRK-linked operators are increasingly undertaking significantly higher-value attacks compared to other threat actors. “This pattern reinforces that when North Korean hackers strike, they target large services and aim for maximum impact,” the report added.

It noted that “this year’s record haul came from significantly fewer known incidents”, including the massive $1.5 billion Bybit hack in February 2025.

DPRK’s distinctive laundering patterns

Not just the hacking process, the laundering of stolen funds is also distinctive, the report said. It noted that more than 60% of laundering was of volume concentrated below $5,00,000 transfer value tranches, despite the total stolen amounts being larger.

“Even while the DPRK consistently steals larger amounts than other stolen fund threat actors, they structure on-chain payments in smaller tranches, speaking to the sophistication of their laundering,” it added.
