Here is the excerpt where he is quoted:

But the flexibility of blockchain is also its biggest risk. Because a blockchain can contain anything; it can contain information that's malicious, harmful, or simply—even deliberately—wrong.

"Blockchain doesn't have any security. It's just a ledger app," explained George Waller, CEO of Blocksafe Technologies, which makes security products for blockchain implementations.

"The myth is that the blockchain is safe and, while the blockchain is immutable, access to it is not," Waller said. Instead, he said that the blockchain used by your company needs to be at least as well-protected as your company network, if not more so. "It could be catastrophic if a hacker got on to it," he said.

Waller said that one particularly worrisome scenario is malware that somehow gets inserted into the blockchain, at which point its greatest strength—the fact that it's immutable—becomes its biggest weakness. He worries that too many organizations are implementing blockchain without also implementing proper access controls and adequate security.
