Security patterns during April showed a shift in how attackers approached crypto systems. Instead of focusing only on smart contract weaknesses, more incidents involved access control manipulation and human interaction points. This included attempts to gain approval rights and influence internal authorization steps across platforms.
Furthermore, the frequency of attacks increased during 2026. Data showed 47 incidents in the early months of the year, compared with 28 in the same period the previous year. This reflected a higher rate of activity across decentralized finance systems.
One technical note stated, “access pathways remain exposed during multi-step authorization processes,” while another observation recorded, “cross-chain infrastructure remains a repeated target across multiple incidents.” The pattern showed continued pressure on bridges and governance systems as usage expanded across DeFi networks.
