"Is anybody in Russia afraid of hitting us again?" the Republican senator said.
Ransomware attacks are "lucrative" and "easy" for the groups behind them, one cyber security expert told Newsweek.
The Florida State Fire Marshal is currently conducting an investigation after a vehicle exploded near a service station. It is suspected the driver was stockpiling gasoline due to the cyberattack on the Colonial Pipeline which has caused severe fuel shortages in some Southeastern states.
President Joe Biden said he does not believe the Russian government is behind the cyberattack on the Colonial Pipeline but has reason to believe the criminals live in Russia.
After a ransomware attack created a halt in fuel supplies, panicked drivers rushed to pumps across several states, resulting in severe shortages and inflated gas prices.
Officials have said there is no need to hoard gas after the nation's biggest fuel pipeline was hit by a cyberattack.
Major fuel pipeline still shutdown several days after a cyberattack, attempts to stave off potential fuel shortages along the East Coast.
The Colonial Pipeline being forced to close has also resulted in widespread fuel shortages, particularly at stations along the East Coast.
"The time of the outage is now approaching critical levels and if it continues to remain down we do expect an increase in East Coast gasoline and diesel prices," IHS Markit Executive Director Debnil Chowdhury said.
"The challenges brought on by the Colonial Pipeline shut down would likely not appear for several days or longer," one analyst estimated.
"The answer for Natanz is to take revenge against Israel," Iran Foreign Ministry spokesman Saeed Khatibzadeh said. "Israel will receive its answer through its own path."

The profile of Kottmann, part of a collective dubbed "APT 69420 Arson Cats," was removed from the social media platform this week after the group claimed to have accessed 150,000 live camera feeds.
Andrew Torba, who launched the alternative social network in 2016, previously branded the culprits of a cyberattack "demon hackers" after a trove of data was reportedly stolen from his platform.
The attacks by the gang allegedly targeted thousands of victims in 2020, including famous internet influencers, sport stars, musicians and their families, Europol said.
"There was minimal security leadership at the top," said the cybersecurity expert, who left SolarWinds after giving his warning.
The Republican senator described the SolarWinds cyberattack—which Secretary of State Mike Pompeo and top GOP lawmakers blame Russia for—as "extraordinary." The president has downplayed it.
President Donald Trump has downplayed the threat from the SolarWinds cyberattack and attempted to cast doubt on Russia's involvement.
A high-profile cybersecurity attack has threatened government agencies and businesses, but the president remains silent on the issue.
Even as critical government agencies acknowledged their computer systems appeared to have been affected, the president has continued to tweet about an election he had already lost.
The fallout from the cyberattack via Texas-based software company SolarWinds appears to be vast, with a slew of powerful U.S. government agencies and businesses, seemingly targeted.
Microsoft has denied a Thursday report claiming that the company was compromised during the recent SolarWinds cyberattacks and used to distribute further attacks.
The former homeland security adviser has said the Biden administration should "assume that any government data or email could be falsified."
"You can't trust electronic communications right now in the unclassified side," former White House Chief Information Officer Theresa Payton warned.
Although the issue was fixed in November 2019, it raises questions about the company's security safeguards.
The State Department is now also believed to have been compromised by hackers reportedly acting under orders from Moscow.
The cyberattack seemingly went undetected for months as hackers were able to sneak into various U.S. government agencies, potentially putting sensitive information at risk of theft.
SolarWinds says on its website its products are currently used by more than 300,000 customers, spanning military, government, business giants and educational institutions.
