WASHINGTON — The Biden administration is sounding more and more pressing alarms about high-profile ransomware assaults which have brought about widespread gasoline shortages, shut meat processing crops and paralyzed hospitals, as officers step up efforts to counter cyberthreats.

Christopher A. Wray, the F.B.I. director, told The Wall Street Journal in an interview published Friday that the ransomware menace was similar to the problem of world terrorism within the days after the Sept. 11, 2001 assault.

“There are plenty of parallels, there’s plenty of significance, and plenty of focus by us on disruption and prevention,” Mr. Wray stated. “There’s a shared accountability, not simply throughout authorities businesses however throughout the non-public sector and even the common American.”

The F.B.I., Mr. Wray stated, is investigating 100 totally different software program variants which were utilized in varied ransomware assaults, demonstrating the size of the issue.

Mr. Wray’s feedback got here on the heels of the Biden administration warning companies on Thursday that they wanted to take pressing steps to enhance their cybersecurity and defend in opposition to ransomware assaults. One such assault this week on a meat processor, JBS, forced the shutdown of nine beef plants and disrupted poultry and pork production. Final yr, a spate of ransomware attacks on hospitals brought about widespread concern.

A ransomware attack on Colonial Pipeline in Might finally prompted the corporate to close down one of many nation’s largest gas pipelines, creating gasoline shortages throughout the East Coast. Instantly after that assault, American officers stated Colonial’s cyberdefenses had been removed from sufficient and that it had accomplished too little to defend itself.

Ransomware is a type of malicious software program that encrypts a company’s knowledge, rendering it unusable till cash is paid to cybercriminals. Colonial Pipeline paid millions of dollars to free its knowledge.

Whereas most ransomware assaults are carried out by prison networks, some Russian and Chinese language teams function with the implicit blessing of their governments. In return, some prison teams do work for these nation’s spy businesses and take steps to ensure native corporations should not affected.

Mr. Wray informed The Journal that Russia was harboring a number of the most harmful ransomware teams.

“If the Russian authorities desires to point out that it’s critical about this subject, there’s plenty of room for them to show some actual progress that we’re not seeing proper now,” Mr. Wray stated.

The Biden administration is on the lookout for methods to strain the Russian authorities to reign of their cybercriminals. Officers anticipate President Vladimir V. Putin of Russia to lift the problem of cybersecurity at his upcoming summit with Mr. Biden.

Anne Neuberger, the deputy nationwide safety adviser for cyber and rising applied sciences, wrote in an open letter to companies on Thursday that the Biden administration was working with companions “to disrupt and deter” attacks. Ms. Neuberger famous “a latest shift in ransomware assaults — from stealing knowledge to disrupting operations.”

Mr. Wray’s feedback constructed on Ms. Neuberger’s be aware. In his interview with The Journal, he stated the pipeline assault had proven Individuals how a cyberattack might influence their day by day lives.

“Now realizing it could actually have an effect on them once they’re shopping for gasoline on the pump or shopping for a hamburger — I believe there’s a rising consciousness now of simply how a lot we’re all on this combat collectively,” he informed the Journal.

Any firm that has waited for the federal authorities’s warnings is already appearing too late, Ofer Israeli, the chief government of Illusive Networks, a cybersecurity agency, stated Friday. However, he added, Mr. Wray’s feedback and the efforts by the administration to raise the precedence of responding to ransomware assaults had been welcome.

“Although it might be stunning to see issues like Colonial Pipeline or JBS in the identical dialog as occasions like 9/11, the 2 should not solely dissimilar,” Mr. Israeli stated. “As attackers proceed chipping away at our nation’s essential infrastructure, vital disruptions are to be anticipated. With no clear course on how you can construct a extra strong protection, these disruptions will grow to be disastrous.”

Final month, the Biden administration put in place an executive order meant as a primary step to bolster cybersecurity, and included efforts to create evaluate boards to review cyberattacks and accumulate classes realized.

Cybersecurity specialists have praised the Biden administration’s steps, but additionally stated that companies should suppose extra creatively in regards to the type of defenses they put in place.

“I might argue that cybersecurity has largely tended to deal with cyberdefense, constructing good deep and large moats, constructing good, high-end, sturdy partitions and focusing your efforts on attempting to cease an adversary from gaining entry,” retired Adm. Michael S. Rogers, a former director of the Nationwide Safety Company, stated in an interview final month.

However Admiral Rogers, who now advises cybersecurity companies, stated these sorts of defenses weren’t sufficient.

“The second part of cybersecurity is not only cyberdefense, however it’s going to be resilience,” he stated. “It’s about this concept about, ‘Hey, so how am I going to proceed to function when an adversary penetrates my community?’”
