Group-IB has estimated that crypto exchanges suffered a total loss of $882 million due to targeted attacks between 2017 and 2018.
Group-IB, an international company that specializes in preventing cyber attacks,has estimated that cryptocurrency exchanges suffered a total loss of $882 million due to targeted attacks in 2017 and in the first three quarters of 2018. According to Group-IB experts, at least 14 crypto exchanges were hacked. Five attacks have been linked to North Korean hackers from Lazarus state-sponsored group, including the infamous attack on Japanese crypto exchange Coincheck, when $534million in crypto was stolen.
This data was included in the annual report, presented by Group-IB CTO, Dmitry Volkov, at the sixth international CyberСrimeCon conference. A separate report chapter is dedicated to the analysis of hackers’ and fraudsters’ activity in crypto industry.
Crypto exchanges: in the footsteps of Lazarus
In most cases, cybercriminals, while attacking cryptocurrency exchanges, use traditional tools and methods, such as spear phishing, social engineering, distribution of malware, and website defacement. One successful attack could bring hackers tens of millions of dollars in crypto funds, whilst reducing the risks of being caught to a minimum: the anonymity of transactions allows cybercriminals to withdraw stolen funds without putting themselves at greater risk.
Spear phishing remains the major vector of attack on corporate networks. For instance, fraudsters deliver malware under the cover of CV spam: they send an email containing a fake CV with the subject line “Engineering Manager for Crypto Currency job” or the file «Investment Proposal.doc» in attachment, that has a malware embedded in the document.
In the last year and a half, the North-Korean state-sponsored Lazarus group attacked at least five cryptocurrency exchanges: Yapizon, Coins, YouBit, Bithumb, Coinckeck. After the local network is successfully compromised, the hackers browse the local network to find workstations and servers used working with private cryptocurrency wallets.
