Yanyan Lesser pleaded guilty in a New York federal court to attempting to hire a hitman over the darkweb to put her ex-boyfriend in a wheelchair. According to information revealed in court, Lesser had paid the fake “murder-for-hire” site $7,000 in Bitcoin before Homeland Security Investigations Received a tip and launched an investigation into the Lesser.
The investigation began in February 2019 after the Homeland Security Investigations Field Office in St. Paul, Minnesota, “received information” from an undisclosed source about Lesser. This tipster, in February, sent HSI information about a user on a murder-for-hire website identified as “Tree1.” Tree1 had conspired with the operator of the website to “commit a crippling assault” of a target in Florida, Special Agent Charles Tolias wrote in the criminal complaint.

Besa Mafia is one of many scam sites the so-called hitman established on the darkweb.

As usual, the investigators had access to the messages between the subject of their investigation and the purported hitman. These murder-for-hire sites–all set up by the same scammer–have a vulnerability that allows a certain cybercrime researcher to record the conversations between the scammer and his customers. Law enforcement could have received the chat logs from the researcher in question. But law enforcement themselves could have backdoored the site in question and obtained the messages without outside assistance.
Below is a sample of the messages sent from Tree1 to the purported hitman.

On February 16, 2019 Tree1 sent 1.26 Bitcoin to a Bitcoin wallet controlled by the scammer behind the murder-for-hire website. On February 19, the user sent another .694 Bitcoin to the same wallet. In addition to the Bitcoin transfers, the user provided a picture to the website owner of the target with the words “broken waist” written across the picture.
Based on the information Tree1 had provided the website, HSI identified and located the person Tree1 had targeted. On February 20, 2019, HSI Orlando interviewed the would-be victim at his house in Orlando, Florida. “He believed that his ex-girlfriend, Yanyan Cui, residing in Buffalo, New York, would be capable of doing something like this as she is unstable,” the Special Agent wrote in the criminal complaint. The ex-boyfriend gave investigators a name and phone number associated with his ex-girlfriend.
Investigators learned that Yanyan Cui still user her married name, Lesser, on official and legal documentation and registration. A DHS Summons to Verizon for the subscriber data associated with the phone number from Lesser’s ex-boyfriend provided law enforcement with accurate subscriber information under her married name.
A few days after investigators visited the ex-boyfriend in Florida, U.S. Customs and Border Protection (CBP)–another law enforcement branch of the Department of Homeland Security–stopped Lesser at a port of entry after she had traveled to Canada for lunch. CBP, aware of the investigation, alerted an HSI Special Agent of her presence. HSI arrived and interviewed Lesser. She gave them access to her phone (but would not give them her password).
