Japan’s national police have pinned North Korean hacking group, Lazarus, as the organization behind several years of crypto-related cyber attacks.
In the public advisory izjava sent out on Oct. 14, Japan’s National Police Agency (NPA) and Financial Services Agency (FSA) sent a warning to the country’s crypto-asset businesses, asking them to stay vigilant of “phishing” attacks by the hacking groupaimed at stealing crypto assets.
The advisory statement is known as “public attribution,” and prema to local reports, is the fifth time in history that the government has issued such a warning.
The statement warns that the hacking group uses social engineering to orchestrate phishing attacks — impersonating executives of a target company to try and bait employees into clicking malicious links or attachments.
„Ova grupa za sajber napad šalje phishing e-poruke zaposlenima koji se lažno predstavljaju kao rukovodioci ciljne kompanije […] putem društvenih mreža sa lažnim nalozima, pretvarajući se da obavljaju poslovne transakcije […] Grupa za sajber napad [tada] koristi malver kao uporište za dobiti pristup mreži žrtve.”
According to the statement, phishing has been a common mode of attack used by North Korean hackers, with the NPA and FSA urging targeted companies to keep their “private keys in an offline environment” and to “not open email attachments or hyperlinks carelessly.”
The statement added that individuals and businesses should “not download files from sources other than those whose authenticity can be verified, especially for applications related to cryptographic assets.”
The NPA also suggested that digital asset holders “install security software,” strengthen identity authentication mechanisms by “implementing multi-factor authentication” and not use the same password for multiple devices or services.
The NPA confirmed that several of these attacks have been successfully carried out against Japanese-based digital asset firms, but didn’t disclose any specific details.

Lazarus Group is allegedly affiliated with North Korea’s Reconnaissance General Bureau, a government-run foreign intelligence group.
Katsuyuki Okamoto of multinational IT firm Trend Micro rekao je The Yomiuri Shimbun that “Lazarus initially targeted banks in various countries, but recently it has been aiming at crypto assets that are managed more loosely.”
They have been accused of being the hackers behind the $650 million Ronin Bridge exploit in March, and were identified as suspects in the $100 million attack from layer-1 blockchain Harmony.
