Businesses including utilities, manufacturers and financial-services companies
are bracing for potential spillover from cyberattacks against Ukraine, as U.S.
officials warn of Russia-linked hacks that could ripple outward across borders
and industries.

Many companies are examining their ties to Ukrainian businesses, as well as
vendors with footprints in the country, as they shore up computer systems
against digital campaigns that could accompany a Russian military advance into
the country.

Hackers in recent weeks have defaced dozens of Ukrainian government websites and
disabled computer systems in at least two of its agencies using destructive
malware known as WhisperGate. Security officials at Microsoft Corp. , which
analyzed the malware used, said it had affected “multiple government, nonprofit
and information technology organizations, all based in Ukraine.”

Microsoft declined to comment further. Ukrainian officials have blamed Russia or
its agents for the attacks. The Kremlin has denied involvement.



The worst-case scenario, cybersecurity experts warn, would be escalating
breaches that mimic the 2017 NotPetya attack on a Ukrainian accounting firm that
allowed hackers to rampage across other corporate networks, eventually causing
an estimated $10 billion in global damage.

“I put my team on high alert right now. This is not the first time we’d see a
political situation resulting in cyberattacks,” said Selim Aissi, chief
information security officer of Blackhawk Network Holdings Inc., a fintech
company based in Pleasanton, Calif.

Blackhawk doesn’t do business in Ukraine, Mr. Aissi said, but that doesn’t mean
the company is shielded from cyberattacks related to that country. Employees who
work in the company’s security operations center, or SOC, are working in shifts
as they watch governments’ security alerts and tweak tools to scan for evidence
of hacks.

“Making sure you always have someone on guard is very critical in times like
this,” Mr. Aissi said. “We have to watch for new ransomware variants. We have to
watch for any other nation-state activities.”

Cyberattacks are central to modern warfare and they can quickly metastasize
across a global economy reliant on tightly connected technology supply chains.
The upshot is that the digital blast radius for potential victims is widening,
said Scott Algeier, executive director of the Information Technology Information
Sharing and Analysis Center.

Mr. Algeier, whose nonprofit informs IT companies about security threats, said
it is regularly communicating with its members about Ukraine. An organization
dedicated to protecting utilities, the Electricity Information Sharing and
Analysis Center, said it is doing the same.

“We need to prepare for the real possibility that the techniques being used
against Ukraine will be used against the U.S. and others,” Mr. Algeier said.

U.S. officials say they are considering new sanctions and export controls aimed
at hobbling the Russian economy should the Kremlin decide to advance its troops
into Ukraine. If Russia launches cyberattacks against the country, President
Biden said last week, “we can respond the same way, with cyber.”

Officials in countries including the U.K., Canada and the U.S. in recent weeks
have urged companies to harden their security measures to ward off a potential
escalation in Russia-backed cyberattacks.

The U.S. Cybersecurity and Infrastructure Security Agency compared the potential
effects of the WhisperGate malware observed in Ukraine to the 2017 NotPetya
hack. That attack, which the White House later attributed to the Russian
military, led to hundreds of millions of dollars in expenses and lost sales at
companies such as FedEx Corp. , drugmaker Merck & Co. and Danish shipping giant
A.P. Moller-Maersk A/S.

U.S. officials worry about disruptions to companies that provide critical
infrastructure, such as utilities or transportation, fearing that a far-off
geopolitical conflict could affect daily life in the U.S.

In a Jan. 18 alert to businesses, CISA said, “If working with Ukrainian
organizations, take extra care to monitor, inspect, and isolate traffic from
those organizations; closely review access controls for that traffic.”

CNN reported that the Department of Homeland Security on Sunday issued a
separate alert warning of cyberattacks targeting U.S. organizations in response
to Washington’s pressure on Russia. DHS didn’t respond to a request for comment
and CISA, an arm of DHS, declined to comment further.
