Crypto lost more than $240 million across 29 incidents in July 2026, up roughly 216% from June's $75.87M, even as the number of attacks fell from 40 to 29. For the second month running, the damage didn't come from clever contract exploits. The same failure class ran through Web2, from a $12.3M rail-industry ransom to a 1TB bank breach that started with one employee's email. Here's the month in security 👇
