The U.S. government on Monday once again cautioned of potential cyber attacks from Russia in retaliation for economic sanctions imposed by the west on the country following its military assault on Ukraine last month.

“It’s part of Russia’s playbook,” U.S. President Joe Biden said in a statement, citing “evolving intelligence that the Russian Government is exploring options.”

The development comes as the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) warned of “possible threats” to U.S. and international satellite communication (SATCOM) networks in the wake of a cyber attack targeting Viasat KA-SAT network, used extensively by the Ukrainian military, roughly around the time when Russian armed forces invaded Ukraine on February 24.

“Successful intrusions into SATCOM networks could create risk in SATCOM network providers’ customer environments,” the agencies said.

To strengthen cybersecurity defences against malicious cyber activity, the government is recommending organizations to mandate the use of multi-factor authentication, ensure that systems are up-to-date and patched against all known vulnerabilities, encrypt data at rest, and maintain offline backups.

“Build security into your products from the ground up — ‘bake it in, don’t bolt it on’ — to protect both your intellectual property and your customers’ privacy,” the U.S. government noted, while also urging companies to scrutinize the provenance of software components, open-source or otherwise, to watch out for supply chain threats.
