Question 1

什么是区块链死投（dead drop）？

Accepted Answer

It is a technique, named by Chainalysis, in which attackers store malware payloads or command-and-control pointers inside on-chain transactions and smart contracts, so infected devices can retrieve them and the setup survives domain seizures and server takedowns.

Question 2

朝鲜和伊朗黑客使用了哪些区块链？

Accepted Answer

According to Chainalysis, the North Korea-linked group UNC5342 used Tron, Aptos, and BNB Smart Chain, routing devices first through Tron and falling back to Aptos, while suspected Iran-linked actors embedded C2 routing data in Bitcoin transactions, including payments to a Bitcoin address historically tied to Satoshi Nakamoto.

Question 3

为什么链上恶意软件活动在过去一年中激增？

Accepted Answer

Chainalysis recorded a 440% rise in malicious writes since July 2025, when high-capacity open-source Chinese AI models became capable of generating malicious code with limited safeguards, though the firm said it could not prove the attackers used those models to increase their output.
