) OPINION

Before: CLAY, NALBANDIAN, and DAVIS, Circuit Judges.

DAVIS, Circuit Judge. Adrian Mitan participated in multiple international fraud schemes to obtain money. He pleaded guilty to conspiracy to commit bank fraud, conspiracy to commit money laundering, and conspiracy to commit a Racketeer Influenced and Corrupt Organizations Act offense. At sentencing, the district court calculated his advisory Sentencing Guidelines range and restitution sum based on the amount of loss from the conspiracies and Mitan’s part in them. Mitan claims the district court’s loss calculations were erroneous on both fronts. On this basis, he attacks the district court’s calculation of his Sentencing Guidelines and the reasonableness of his sentence. He also challenges the restitution amount. For the reasons below, we AFFIRM.

I.

A. Offense Conduct For nearly a decade, Adrian Mitan—a Romanian national—ran cybercrime operations that stole sensitive financial data, exploited vulnerabilities in banking systems, and laundered illicit

cash. As a result, federal grand juries in two states indicted him in three separate cases for his role in three conspiracies. We discuss each conspiracy in turn.

First, the “vishing” conspiracy: On November 14, 2017, Mitan was indicted in the Western District of North Carolina for conspiracy to commit bank fraud in violation of 18 U.S.C. §§ 1344 and 1349. Mitan and his co-conspirators used Voice over Internet Protocol (“VoIP”) technology to deceive victims into disclosing sensitive financial information. To carry out the scheme, Mitan and his co-conspirators hacked VoIP systems, installed malware, and initiated thousands of automated robocalls. These calls falsely warned victims that hackers had compromised their debit or credit card accounts and requested victims to enter sensitive account information to avoid having their accounts suspended. As a result, victims unwittingly provided debit card numbers, PINs, and CVV numbers (security codes). Then, Mitan’s team cloned the debit cards and used them to withdraw cash from ATMs and make unauthorized purchases. This operation compromised at least 2,130 debit cards.

Second, the “brute-force” phishing conspiracy: On July 5, 2018, an Eastern District of Kentucky grand jury indicted Mitan for conspiracy to commit money laundering in violation of 18 U.S.C. § 1956(h). This conspiracy involved Mitan and his co-conspirators phishing thousands of credit and debit card numbers. Once they had the numbers, they used some form of cryptological trial-and-error system commonly referred to as “brute force” to obtain missing security details, such as CVV codes and expiration dates. And once they compiled complete card data, Mitan’s team encoded the information onto blank magnetic strips, which they then used to make clone cards. They used these cloned cards to withdraw money from victims’ accounts at ATMs, then converted the stolen cash into Bitcoin (or some other form of currency) and, at Mitan’s direction, transferred it overseas. Investigators linked Mitan to about 16,000 compromised credit

or debit card numbers, resulting in significant losses. For instance, over a two-day period, his network withdrew $61,000 from a single credit union using seventy-five cloned cards.

Third, the “online auction fraud” conspiracy: On July 5, 2018, an Eastern District of Kentucky grand jury indicted Mitan for conspiracy to commit a Racketeer Influenced and Corrupt Organizations Act (“RICO”) offense in violation of 18 U.S.C. § 1962(d). This scheme involved an online auction scam run by the organization known as the Alexandria Online Auction Fraud Network (“AOAFN”). Under this scheme, Mitan and his co-conspirators created fake postings on eBay, Craigslist, Amazon, and other auction websites claiming to sell high-value items like automobiles. Unsuspecting buyers sent payments via prepaid cards, wire transfers, or money orders, expecting to receive their purchases. But because the items did not exist, the buyers never received the goods. To clean their profits, the conspirators funneled the funds through Bitcoin wallets, converted them into fiat currency, and laundered them through multiple accounts. In total, this scheme defrauded victims of at least $2.7 million.

B. Plea Agreement and Sentencing To resolve all the charges stemming from these three separate conspiracies, Mitan entered into a global plea agreement. As part of the global deal, he agreed to consolidate all three cases in the Eastern District of Kentucky. Mitan pleaded guilty to one count under each indictment: conspiracy to commit bank fraud in the North Carolina-filed case; conspiracy to commit money laundering in one Kentucky-filed case; and conspiracy to commit a RICO offense in the other Kentucky-filed case.

In August 2021, the district court conducted a joint sentencing hearing for all three cases.

The presentence report (“PSR”) created two groups to calculate Mitan’s base offense level: Group One accounted for the RICO and bank-fraud conspiracies, and Group Two encompassed the

money-laundering conspiracy. The “grouping guidelines” under the U.S. Sentencing Guidelines (“U.S.S.G.”) instruct the sentencing court to first determine the offense level for each group by applying the offense level for the “most serious” offense within a group and then follow additional procedures to combine and arrive at one final adjusted offense level for the groups. U.S.S.G. Chapter 3, Part D. The PSR proceeded along these lines for the two groups. But the district court disagreed with this grouping. It determined that all three offenses should be grouped together— with the most serious offense, the money-laundering charge, serving as the basis for Mitan’s base offense level. This process resulted in an adjusted offense level of 35 for Mitan, which the court subsequently reduced by three points for Mitan’s acceptance of responsibility.

Mitan’s Guidelines calculation included an 18-level enhancement under U.S.S.G.

§ 2B1.1(b)(1)(J) for causing losses of more than $3.5 million and less than $9.5 million. As relevant here, the PSR applied a two-point enhancement for sophisticated laundering, and another two-point enhancement reflecting that a significant part of the fraudulent schemes charged were committed overseas. U.S.S.G. §§ 2S1.1(b)(3); 2B1.1(b)(10)(B) (2018). Mitan objected to the loss amount and the sophisticated laundering enhancement both in his sentencing memorandum and at the sentencing hearing.

First, he challenged the government’s use of the intended loss to calculate the total loss amount. He maintained that the government failed to show that he used many of the compromised cards it attributed to him, or that those cards were even usable. Thus, he argued, the amount attributed to those cards overstated his culpability and should not be included in his loss calculation. The court rejected Mitan’s argument, finding that empirical information supported the government’s estimate of a $500 loss per card. And based on that estimate, the district court

tallied the loss amount at over $6.5 million.1 Consequently, the court applied the 18-level sentencing enhancement under U.S.S.G. § 2B1.1(b)(1)(J) and overruled Mitan’s objection.
