When sending bitcoins, you need to check whether the address of a phishing site is
Korea’s first virtual asset exchange, Kobit (CEO Sejin Oh), operated the FDS (Fraud Detection System) to prevent phishing damage worth 50 million won for one customer.
On the 15th, an e-mail from customer A arrived in front of the Kobit customer center. Thanks to Kobit, he was thankful that he was able to prevent his virtual asset phishing damage from becoming more significant. Mr. A signed up for Corbit in March last year, and over the course of a month from the middle of the same month, he steadily bought bitcoins worth 70 million won in our money. However, this person repeated the pattern of withdrawing bitcoins immediately after purchase and sending them to another depository. Accordingly, the Corbit review team, which had doubts about the withdrawal pattern and the deposit destination, withheld the withdrawal of 27 million won and requested the customer to explain the deposit destination.
Afterwards, Mr. A sent data on the deposit destination to Corbit, and as a result of the confirmation, the site was found to be a phishing site pretending to be’Gemini’, one of the representative virtual asset exchanges in the United States. The Corbit evaluation team shared this with the Customer Satisfaction (CS) team, and the Customer Satisfaction Team contacted Mr. A again. At first, Mr. A, who received a call from the Corbit customer satisfaction team, did not believe this. However, the person in charge of the Customer Satisfaction Team kept talking on the phone and informed the official website of the Gemini Exchange and encouraged customers to access it directly.
Mr. A actually tried to access the Gemini site, but when he couldn’t log in, he realized that the deposit destination where he had sent bitcoins was a phishing site. The Corbit customer satisfaction team advised the customer to go to a phishing site and retrieve bitcoins as quickly as possible. However, I couldn’t find a bitcoin worth 20 million won, which had already gone to a phishing site. Fortunately, however, thanks to the withdrawal from Corbit, the remaining 50 million won worth of bitcoins held by Mr. A were not affected by phishing.
As a result of confirming how he became aware of the phishing site from Mr. A, it was revealed that he received the address of the phishing website from a Japanese friend he learned from overseas travel, saying that it is a site operated by his sister. As a test, Mr. A, who sent about 1 million won of bitcoin to a phishing site, quickly confirmed that 400,000 won of profit was made, and after that, he continued to transfer bitcoins. While trying to send coins, I almost suffered more damage.
“If you are using an overseas exchange, it is especially important to carefully check that the website is the official website of the exchange,” said Kobit CEO Se-jin Oh. Revealed.
On the other hand, Kobit also prevented voice phishing damage for all virtual assets worth 40 million won that a customer owned last month.
