How Hackers Targeted South Korea’s Servers For Cryptojacking

South Korea’s government servers became victims of cryptojacking as hackers used computation powers to mine cryptocurrency. Last year, there were at least 332 million cryptojacking incidents worldwide.

The crypto ecosystem indeed offers revolutionary technology with various applications. However, bad actors are also attracted to the crypto ecosystem as they conduct different types of sophisticated crimes.

How South Korea’s Servers Became Victims of Cryptojacking

According to a South Korean outlet, MBN, the bad actors accessed the passwords of Daejeon City’s administrator accounts. Then, the attacker infected the system with malware such that it can be used for crypto mining purposes.

Finally, during a government joint audit on June 2, 2023, it was discovered that the servers were infected with malware. Then, the city’s cyber department reported the incident to South Korea’s National Intelligence Services. 

Such attacks where victims’ devices are used to mine cryptocurrencies are called cryptojacking.

Europol reported collaborating with the Ukrainian National Police to arrest a 29-year-old individual. Allegedly, the individual mined over $2 million worth of cryptocurrencies through cryptojacking.

“The 29-year-old individual was apprehended in Mykolaiv, Ukraine, on 9 January. Three properties were searched to gather evidence against the main suspect. 

The arrest comes after months of intensive collaboration between Ukrainian authorities, Europol and a cloud provider, who worked tirelessly to identify and locate the individual behind the widespread cryptojacking operation,” said Europol.

On a separate note, Europol had various successful seizures of illicit crypto funds last year. For example, in March 2023, Europol seized nearly $50 million worth of Bitcoin in a joint operation against ChipMixer.
