The White House has issued its starkest warning that Russia may be planning cyberattacks against critical-sector U.S. companies amid the Ukraine invasion.

[…]

Context: The alert comes after Russia has lobbed a series of digital attacks at the Ukrainian government and critical industry sectors. But there’s been no sign so far of major disruptive hacks against U.S. targets even as the government has imposed increasingly harsh sanctions that have battered the Russian economy.

• The public alert followed classified briefings government officials conducted last week for more than 100 companies in sectors at the highest risk of Russian hacks, Neuberger said. The briefing was prompted by “preparatory activity” by Russian hackers, she said.
• U.S. analysts have detected scanning of some critical sectors’ computers by Russian government actors and other preparatory work, one U.S. official told my colleague Ellen Nakashima on the condition of anonymity because of the matter’s sensitivity. But whether that is a signal that there will be a cyberattack on a critical system is not clear, Neuberger said.
• Neuberger declined to name specific industry sectors under threat but said they’re part of critical infrastructure ­– a government designation that includes industries deemed vital to the economy and national security, including energy, finance, transportation and pipelines.

On Friday, Colonial Pipeline took many of its systems offline in the wake of a ransomware attack. With systems offline to contain the threat, the company's pipeline system is inoperative. The system delivers approximately 45% of the East Coast's petroleum products, including gasoline, diesel fuel, and jet fuel.

Colonial Pipeline issued a statement Sunday saying that the US Department of Energy is leading the US federal government response to the attack. "[L]eading, third-party cybersecurity experts" engaged by Colonial Pipeline itself are also on the case. The company's four main pipelines are still down, but it has begun restoring service to smaller lateral lines between terminals and delivery points as it determines how to safely restart its systems and restore full functionality.

Colonial Pipeline has not publicly said what was demanded of it or how the demand was made.

Google’s Project Zero has exposed a sophisticated watering-hole attack targeting both Windows and Android:

Some of the exploits were zero-days, meaning they targeted vulnerabilities that at the time were unknown to Google, Microsoft, and most outside researchers (both companies have since patched the security flaws). The hackers delivered the exploits through watering-hole attacks, which compromise sites frequented by the targets of interest and lace the sites with code that installs malware on visitors’ devices. The boobytrapped sites made use of two exploit servers, one for Windows users and the other for users of Android

The use of zero-days and complex infrastructure isn’t in itself a sign of sophistication, but it does show above-average skill by a professional team of hackers. Combined with the robustness of the attack code — ­which chained together multiple exploits in an efficient manner — the campaign demonstrates it was carried out by a “highly sophisticated actor.”

[…]

The modularity of the payloads, the interchangeable exploit chains, and the logging, targeting, and maturity of the operation also set the campaign apart, the researcher said.

No attribution was made, but the list of countries likely to be behind this isn’t very large. If you were to ask me to guess based on available information, I would guess it was the US — specifically, the NSA. It shows a care and precision that it’s known for. But I have no actual evidence for that guess.

All the vulnerabilities were fixed by last April.
