UnitedHealth Group on Thursday said it expects to restore Change Healthcare’s systems by mid-March, offering a potential resolution to the ransomware attack that has disrupted crucial operations across the U.S. health-care system.
The company discovered that a cyber threat actor breached part of the Change Healthcare’s information technology network on Feb. 21, according to a filing with the Securities and Exchange Commission.
UnitedHealth isolated and disconnected the impacted systems “immediately upon detection” of the threat, the filing said, but doing so interrupted pharmacy services, payment platforms and medical claims processes.
UnitedHealth said in a release Thursday that electronic prescribing is “now fully functional,” and payment transmission and claim submissions are currently available. The company said it expects electronic payment functionality to be restored by March 15, and it will start to test connectivity with its claims network and software on March 18.
There is “no indication” that any other UnitedHealth systems were compromised in the attack, the company said in the release.
“We are committed to providing relief for people affected by this malicious attack on the U.S. health system,” UnitedHealth CEO Andrew Witty said in the release.
On Friday, UnitedHealth announced a temporary funding assistance program to help health-care providers that are experiencing cash flow problems as a result of the attack. The company said Thursday it is providing “further funding solutions” for providers, which will mean “advancing funds each week.”
UnitedHealth said it recognizes that the program does not meet the needs of every provider, so it is expanding the program to include those ” who have exhausted all available connection options, and who work with a payer who has opted not to advance funds to providers during the period when Change Healthcare systems remain down,” according to the release.
UnitedHealth said the advances will not need to be repaid until claims flows are back to normal.
In late February, Change Healthcare said that ransomware group Blackcat was behind the cybersecurity attack. Blackcat, also called Noberus and ALPHV, steals sensitive data from institutions and threatens to publish it unless a ransom is paid, according to a December release from the U.S. Department of Justice.
Ransomware attacks can be particularly dangerous within the health-care sector, as they can cause immediate harm to patients’ safety when life-saving systems go dark. UnitedHealth did not specify in the release what kind of data was compromised in the attack or confirm whether the company has paid a ransom to bring its systems back online.

Micron reported better-than-expected earnings and revenue on Tuesday as well as a robust forecast for the current quarter.
The stock rose in extended trading.
Here’s how the company did in comparison with the LSEG consensus:
Earnings per share: $3.03, adjusted, vs. $2.86 expected
Revenue: $11.32 billion vs. $11.22 billion expected
Micron said revenue in the current period, its fiscal first quarter, will be about $12.5 billion, versus the $11.94 billion average analyst estimate per LSEG.
The company said it had $3.2 billion, or $2.83 per share in net income, versus $887 million, or 79 cents in the year-ago period.
Micron shares have nearly doubled so far in 2025. The company makes memory and storage, which are important components for computers. Micron has been one of the winners of the artificial intelligence boom. That’s because high-end AI chips like those made by Nvidia require increasing amounts of high-tech memory called high-bandwidth memory, which Micron makes.
“As the only U.S.-based memory manufacturer, Micron is uniquely positioned to capitalize on the AI opportunity ahead,” Micron CEO Sanjay Mehrotra said in a statement.
Overall company revenue rose 46% on a year-over-year basis during the quarter.
Micron’s largest unit, which sells memory for cloud providers, reported $4.54 billion in sales during the quarter, more than tripling on a year-over-year basis.
However, the company’s core data center business unit saw sales decline 22% on an annual basis to $1.57 billion in revenue.
Google-owned YouTube on Tuesday said it will soon allow previously banned accounts to apply for reinstatement, rolling back a policy that had treated violations as permanent.
The change applies to channels removed for posting Covid-19 or election-related misinformation, according to a letter fromAlphabet lawyer Daniel Donovan to House Judiciary Chair Jim Jordan, R-Ohio. Previously, those types of offenses carried lifetime bans.
“Today, YouTube’s Community Guidelines allow for a wider range of content regarding Covid and elections integrity,” Donovan wrote.
YouTube wrote on X that it will be a limited pilot project open to a subset of creators as well as channels that were terminated under policies the company has since retired. YouTube also said its new reinstatement program will launch soon.
Among channels previously banned under those rules were some associated with Deputy FBI Director Dan Bongino, former Trump chief strategist Steve Bannon and Health and Human Services Secretary Robert F. Kennedy Jr. It’s not yet clear whether those channels will be reinstated.
This move follows mounting Republican pressure on tech companies to reverse Biden-era speech policies on vaccine and political misinformation. In March, Rep. Jordan subpoenaed Alphabet CEO Sundar Pichai, alleging YouTube was a “direct participant in the federal government’s censorship regime.”
In 2021, YouTube said it would remove content that spread misinformation about all approved vaccines.
Donovan wrote that during the pandemic, senior Biden administration officials pressed the company to remove certain Covid-related videos that did not technically violate YouTube’s policies.
In the letter, Donovan said this pressure was “unacceptable and wrong.”
YouTube ended its stand-alone Covid misinformation rules in December 2024, according to Donovan’s letter.
YouTube “will not empower third-party fact-checkers” to moderate content and will continue to enable “free expression” on the platform, Donovan wrote. While Donovan writes that YouTube has not used fact-checkers, the platform has produced programs that are meant to label context on videos.
Similarly, Meta said in January that it had eliminated its fact-checking program on Facebook and Instagram.
YouTube has a feature that will display information panels with links to independent fact checks under videos. The feature says it provides more context on videos across YouTube with information from third-party sources.
In 2017, Google launched a fact-checking tool that would display labels on search and news results.

Amazon plans to close all of its Fresh supermarkets in the U.K., in the latest recalibration of its grocery strategy.
The company said in a Tuesday blog that it’s preparing to close all 19 of its Fresh U.K. stores, “following a thorough evaluation of business operations and the very substantial growth opportunities in online delivery.” Five of the Fresh locations are expected to be converted into Whole Foods stores, Amazon said.
Amazon opened its first Fresh location outside the U.S. in London in 2021, about a year after it debuted the store concept in the Woodland Hills neighborhood of Los Angeles. Fresh stores offer cheaper prices and more mass-market items compared to Whole Foods, the upscale supermarket chain Amazon acquired for $13.7 billion in 2017. Many of the stores also feature Amazon’s cashierless “Just Walk Out” technology.
The Fresh store pullback in the U.K. comes as Amazon has continued to adjust its grocery ambitions. The company has slowed expansion of its Fresh grocery chain and Go cashierless stores in the U.S. It still maintains 500 Whole Foods locations and has opened mini “daily shop” Whole Foods stores in New York City.

At the same time, Amazon CEO Andy Jassy and other company executives have touted the success of sales of “everyday essentials” within its online grocery business, which refers to items like canned goods, paper towels, dish soap and snacks.
Jassy told investors at the company’s annual shareholder meeting in May that he remains “bullish” on grocery, calling it a “significant business” for Amazon.
The company on Tuesday also said that it plans to offer same-day delivery of groceries, including perishable items, in the U.K. beginning next year.
