US gas prices could soon be headed for the highest level since 2014 due to a cyberattack that crippled the country�s biggest fuel pipeline system, according to the American Automobile Association (AAA).

Average US pump prices increased to $2.967 per gallon and an increase of 3 more cents would make the national average the most expensive since November 2014.

A ransomware attack shut down a gasoline and diesel pipeline running 5,500 miles along the entire US East Coast on Friday.

The outage is expected to last a full week or more, but Colonial said Monday it will substantially restore operational service by the end of this week.

The shutdown has caused panic buying amid gas shortage on the East Coast, with Amrican drivers seeking to fill up tanks as a precaution as gasoline demand picks up ahead of summer vacation season amid the COVID-19 crisis.

US traders have now scrambled to import fuel from Europe as the Biden administration responded by invoking emergency powers to enable truckers to transport more fuel.

The states of Florida, Georgia, Alabama, South Carolina, North Carolina, and Tennessee, which heavily rely on the shut down line for fuel, suffered acute shortages and spikes in prices at the pump during previous shutdowns.

I went to five stations before I found a station that had premium only, said a Florida driver.

But experts urged drivers not to panic buy.

Motorists are well advised not to strain the system by filling up ... they may make the problem much more severe, said Patrick DeHaan, head of petroleum analysis at fuel tracking firm GasBuddy.

Ransomware attackers typically encrypt a company�s data, locking the firm out of its own systems until a ransom is paid.

It is still unclear whether the Colonial Pipeline Company pays its hackers.

Biden says ‘no evidence� Russia responsible for pipeline cyberattack

US President Joe Biden, on Monday, rejected claims of Russian involvement and blamed transnational criminals for cyberattack.

So far there�s no evidence from our intelligence people that Russia is involved, Biden said.

He, however, said that the ransomware used is in Russia, and Russia therefore has some responsibility to deal with this.

Rumors surfaced of Russian involvement after some US media outlets took the opportunity to link the hackers to Russia or even its government.

CNN has claimed that ‘DarkSide,� a criminal hacking organization believed to be behind the US attack, is based in a Russian-speaking country.

Biden said he will discuss the cyberattack with Russian President Vladimir Putin when they meet face to face.

The US president has previously said he will meet his Russian counterpart sometime in June, possibly during his visit to Europe for the G7 summit that month.
