LinkedIn co-founder Reid Hoffman has expressed concerns about Silicon Valley's cautious stance towards cryptocurrencies, citing their use in ransomware attacks as a primary reason. Hoffman described cryptocurrencies as the "preferred tool" for hijacking critical infrastructure, such as hospitals. In response, blockchain investigator ZachXBT pointed out that the crypto community also fears LinkedIn, as it is a favored platform for North Korean hackers to spread malware, exploiting weak detection mechanisms that have resulted in millions of dollars in theft.
