A team of cybersecurity researchers at Stony Brook University has uncovered a new way for scammers to steal from unsuspecting cryptocurrency users. They have posted a paper to the arXiv preprint server describing the new crypto scam and how users can protect themselves.

Cryptocurrency is a type of digital currency run on a secure online platform. One example is Coinbase. Crypto currency is stored in a crypto wallet. In this new study, the team in New York reports that scammers have found a way to get people to redirect crypto payments away from intended recipients and toward wallets held by the scammers.

The researchers call the scam typosquatting. It involves setting up Blockchain Naming Systems (BNS) that are similar to those used by well-known entities. It exploits the use of simple word-based addresses rather than the complicated and hard-to-remember letter and digit codes commonly associated with crypto wallets.

🚀 Q: How might Trump’s administration impact AI development in the US? A: Trump aims to make America “first in AI” by dismantling Biden’s policy framework and reducing government regulation, potentially leading to skyrocketing growth in AI, cryptocurrencies, blockchain, Web3, and augmented reality.

🔓 Q: What’s J.D. Vance’s stance on AI development? A: Trump’s potential VP J.D. Vance supports open source AI and decentralized power, aiming to prevent large tech companies from steering regulation and allowing smaller innovators to compete.

“What the FBI uncovered in this case is essentially a new twist to old-school financial crime,” Jodi Cohen, the special agent in charge of the FBI’s Boston division, said in a statement. “What we uncovered has resulted in charges against the leadership of four cryptocurrency companies, and four crypto ‘market makers’ and their employees who are accused of spearheading a sophisticated trading scheme that allegedly bilked honest investors out of millions of dollars.”

Liu Zhou, a “market maker” working with MyTrade MM, allegedly told promoters of NexFundAI that MyTrade MM was better than its competitors because they “control the pump and dump” allowing them to “do inside trading easily.”

An FBI spokesperson told CoinDesk that there was limited trading activity on the coin but didn’t share additional information. On a Wednesday press call, Joshua Levy, the acting US attorney for the District of Massachusetts, said trading on the token was disabled, according to CoinDesk.

“When a new user logs into the server, it immediately stops all ‘noisy’ activities, lying dormant until the server is idle again. After execution, it deletes its binary and continues to run quietly in the background as a service.”

It’s worth noting that some aspects of the campaign were disclosed last month by Cado Security, which detailed an activity cluster that targets internet-exposed Selenium Grid instances with both cryptocurrency mining and proxyjacking software.

Specifically, the fileless perfctl malware has been found to exploit a security flaw in Polkit (CVE-2021–4043, aka PwnKit) to escalate privileges to root and drop a miner called perfcc.

A massive infostealer malware operation encompassing thirty campaigns targeting a broad spectrum of demographics and system platforms has been uncovered, attributed to a cybercriminal group named “Marko Polo.”

The threat actors use a variety of distribution channels, including malvertising, spearphishing, and brand impersonation in online gaming, cryptocurrency, and software, to spread 50 malware payloads, including AMOS, Stealc, and Rhadamanthys.

According to Recorded Future’s Insikt Group, which has been tracking the Marko Polo operation, the malware campaign has impacted thousands, with potential financial losses in the millions.

The FBI says that 2023 was a record year for cryptocurrency fraud, with total losses exceeding $5.6 billion, based on nearly 70,000 reports received through the Internet Crime Complaint Center (IC3).

This marks a 45% increase in losses compared to the previous year, driven primarily by investment fraud, which accounted for 71% of the total cryptocurrency losses. Other types of fraud contributing to the statistics include tech support scams, call center fraud, and government impersonation.

The vast majority of the reported losses ($4.8 billion) were incurred by U.S. citizens, followed by Cayman Islands ($196M), Mexico ($127M), Canada ($72M), the UK ($59M), India ($44M), and Australia ($25M).
