According to Joe Biden’s National Security Adviser Jake Sullivan, the United StatePresident will speak directly about cryptocurrency regarding its role in the attack on the Colonial Pipeline and other ransomware breaches. 

In a Monday White House press briefing, Sullivan said U.S. officials seemingly including Biden would like to see an action plan regarding ransomware attacks during the president’s visit to the G7 summit this weekend. The National Security Adviser said this plan should address the resilience of such attacks, how to share information with other democracies, and “how to deal with the cryptocurrency challenge.”

Sullivan said crypto “lies at the core of how these ransom transactions are played out,” citing cyberattacks as a “national security priority” for the U.S. government, particularly for “critical infrastructure.” His remarks follow hackers breaching the network behind Colonial Pipeline in May, reportedly forcing the firm to pay $4.4 million in ransom.

“It’s gotta become a priority on a going forward basis,” said Sullivan, referring to the G7 addressing such ransomware attacks. He described the issue as a “different order of magnitude of a security threat that the alliance has to concern itself with in a way that it hasn’t historically.”

President Biden has, as an individual, largely been silent on crypto and blockchain both as vice president under Barack Obama and in his campaign for office. Last July, then candidate Biden said he didn’t hold Bitcoin (BTC) in a Twitter update following a massive hack that took over high-profile accounts and asked their followers to send crypto.

However, his administration is reportedly reviewing existing rules around crypto and determining whether new restrictions are needed to protect investors following volatility in the market. Since hitting an all-time high price of roughly $65,000 in April, Bitcoin has fallen more than 44% to reach $35,588 at the time of publication.

The G7 summit is scheduled to be held in the United Kingdom from June 11-13. It will be Biden’s first foreign trip acting as U.S. president since his inauguration in January.
