The victims of the hackers were both centralized and decentralized projects, and the main reasons for the success of the hacks were the errors of the operating infrastructure and the successful use of the methods of social engineering.
“The main conclusion based on the results of the quarter is not new attack techniques, but the old methods remain effective. Most of all losses are caused by errors in multi -signature management. Despite the fact that the vulnerabilities of smart contracts remain a problem, the greatest losses are associated with the human factor, processes and access systems, ”analysts said.
The total losses of decentralized finance protocols (Defi) amounted to $ 81 million, which confirms the tendency to reduce losses in this cryptor segment, Hacken experts noted. According to them, the third quarter in a row the largest attack was associated with the vulnerability of multi -signature wallets.
In the second half of last year, the WAZIRX exchange lost $ 235 million, and the Radiant Capital – $ 55 million. In each case, the SAFE multi -subscription infrastructure was used. The problem is not in smart contracts, but in the absence of proper operating safety, weak signing processes and insufficient transaction verification tools, Hacken experts summed up.
Previously, CHAINALYSIS experts Reportedthat the darknet platforms return to the use of the first cryptocurrency to pay after the divisting of the Monero (XMR) coin from exchanges.
