Chaos ransomware hits Optima Tax Relief, leaks 69GB of data

NEWYou can now listen to Fox News articles!

Cyberattacks on financial service providers are no longer isolated events. In recent years, tax preparation companies, accounting software vendors and data brokers have all found themselves in the crosshairs of increasingly aggressive ransomware gangs. These attacks don’t just disrupt operations but also expose deeply personal financial information that can fuel identity theft, fraud and long-term reputational damage.

Now, Optima Tax Relief, one of the most prominent tax resolution firms in the U.S., has joined that growing list. A ransomware group called Chaos claims to have breached Optima’s systems, stealing 69 GB of data before encrypting internal servers.

Customer case files and personal information exposed

The data stolen in the attack includes what appears to be corporate documents and sensitive customer case files. Tax documents are especially valuable to cybercriminals. They often contain Social Security numbers, home addresses, phone numbers and other identifiers that can be used to commit financial fraud or impersonation.

Sources familiar with the incident told BleepingComputer this was a double-extortion attack. That means Chaos not only stole the data but also encrypted Optima’s systems, presumably demanding a ransom in exchange for access and non-disclosure. The firm has not yet commented publicly on whether it plans to pay the ransom or notify affected individuals.

The attackers listed Optima on their leak site earlier this week. While the full dataset has not been published, the leak already raises concerns over regulatory compliance and consumer protection, especially given the sensitive nature of the firm’s work.

Optima Tax Relief has not released an official statement regarding the breach. There has been no confirmation about whether law enforcement or federal agencies are involved in the investigation. If you’ve ever used its services, assume your data could be at risk.

We reached out to Optima Tax Relief for a comment but did not hear back before our deadline.

A new ransomware group with high-value targets

Chaos ransomware first emerged in March 2025, when it claimed responsibility for five separate breaches. The group is not connected to the “Chaos ransomware builder,” a DIY toolkit that’s been in circulation since 2021. Instead, this version of Chaos is believed to be run by a coordinated team that is strategically targeting organizations with access to large amounts of personally identifiable information.

Optima is not the only high-profile victim. In May, Chaos claimed to have breached the Salvation Army, though the organization has not publicly confirmed the attack or responded to media inquiries.

6 ways you can stay safe from Optima data breach

If your information was part of the Optima breach or any similar one, it’s worth taking a few steps to protect yourself.

1. Consider identity theft protection services: Since the Optima data breach exposed personal and financial information, it’s crucial to stay proactive against identity theft. Identity theft protection services offer continuous monitoring of your credit reports, Social Security number and even the dark web to detect if your information is being misused. See my tips and best picks on how to protect yourself from identity theft.

2. Monitor your accounts and transactions: The Optima data breach might have revealed bank details to attackers, which means they can misuse those details to steal your money. You should check your online accounts and transactions regularly for any suspicious or unauthorized activity. If you notice anything unusual, immediately report it to the service provider or authorities. You should also review your credit reports and scores to see if there are any signs of identity theft or fraud. To report identity theft, visit the FTC’s IdentityTheft.gov.

3. Contact your bank and credit card companies: Since Optima hackers might have obtained bank and credit card information, they could use it to make purchases or withdrawals without your consent. You should inform your bank and credit card companies of the situation. They can help you freeze or cancel your cards, dispute any fraudulent charges and issue new cards for you. You should also contact one of the three major credit reporting agencies — Equifax, Experian or TransUnion — and request a fraud alert to be placed on your credit file. This will make it more difficult for identity thieves to open new accounts in your name without verification.

4. Use personal data removal services: The data breach leaks loads of information about you, and all this could end up in the public domain, which essentially gives anyone an opportunity to scam you. One proactive step is to consider personal data removal services, which specialize in continuously monitoring and removing your information from various online databases and websites. Check out my top picks for data removal services here.

Get a free scan to find out if your personal information is already out on the web.

5. Have strong antivirus software: Optima hackers most likely have people’s email addresses and full names, which makes it easy for them to send you a phishing link that installs malware and steals all your data. These messages are socially engineered to catch them, and catching them is nearly impossible if you’re not careful. However, you’re not without defenses.

The best way to safeguard yourself from malicious links is to have antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

6. Enable two-factor authentication: While passwords weren’t part of the data breach, you still need to enable two-factor authentication (2FA). It gives you an extra layer of security on all your important accounts, including email, banking and social media. Two-factor authentication requires you to provide a second piece of information, such as a code sent to your phone, in addition to your password when logging in. This makes it significantly harder for hackers to access your accounts, even if they have your password. Enabling 2FA can greatly reduce the risk of unauthorized access and protect your sensitive data.

Kurt’s key takeaway

The Optima breach is not an isolated event, but part of a larger failure to adapt to the sophistication of modern ransomware groups. When companies with access to tax and identity data are compromised, it’s not just an internal issue; it becomes a national one. For an industry built on trust, breaches like this erode public confidence in systems that are already strained. Attacks like these raise fresh concerns about the cybersecurity preparedness of companies that handle tax and financial data. Unlike login credentials or email addresses, stolen tax information cannot be easily reset. For victims, the consequences of such a breach could stretch across years.

Press Room

All year on The Vergecast, we’ve been tracking the many bizarre and problematic actions of FCC Chairman Brendan Carr. There has been a lot to discuss! Then, this week, ahead of one of our last episodes of the year, Carr appeared in front of the Senate Commerce Committee and spent three hours explaining how he thinks about his job, the FCC, and the state of online communication and entertainment. It was a lot.

On this episode of The Vergecast, we begin with a dissection of Carr’s testimony, his threats against broadcasters, and the ways in which he’s using old ideas about content delivery to get his political way. Nilay and David walk through some of Carr’s most important quotes, explain the history of broadband regulation, and look ahead to how Carr might bring these same tactics to internet regulation next year.

Also, an important housekeeping note: The Vergecast will be live at CES! We’ll be at the Brooklyn Bowl in Las Vegas, at 3:30PM on Wednesday, January 7th. There will be podcasting, and hanging out, and bowling. It’s going to be great, and if you’re going to be in Vegas we’d love to see you there.

Until then, if you want to know more about everything we discuss in this episode, here are some links to get you started, first on Brendan Carr:

AI photo match reunites Texas woman with lost cat after 103 days

NEWYou can now listen to Fox News articles!

Holiday gatherings and year-end travel often lead to a spike in missing pets. Doors open more often, routines shift and animals can slip outside in a moment of confusion.

New Year’s Eve creates loud fireworks, and shelters report some of their busiest nights of the entire year. Amid all that, one Texas family just experienced a heartwarming reunion thanks to an AI photo matching on Petco Love Lost.

How AI photo matching kept the search going

Pam’s 11-year-old indoor cat, Grayson, had never been outside alone. She believes he slipped out while she unloaded groceries at their home in Plano, Texas. The moment she realized he was gone, she acted fast.

She said, “We went up and down the streets day and night. We went online in the neighborhood and on Love Lost. We put up flyers all over the neighborhood. Friends and neighbors were looking for him. I went to the animal shelter, posted him there, and went every day for over a month, hoping to find him.”

Pam uploaded Grayson’s photo to Petco Love Lost right away. She checked her daily match alerts and hoped she would see his familiar face pop up. She told CyberGuy, “I received match alerts almost every day from Lost Love, but never saw Grayson. His profile had been on their site for over 90 days.”

The moment everything changed

Missy, a nearby resident, spotted a thin cat in an alley near her home. She brought him inside, took a picture of him and then turned to Love Lost to see if anyone had reported a missing cat like him.

Missy explained how simple the process felt. “I used Lost Love to reunite them,” she said. “I uploaded a photo of the cat that we found, and it was matched through AI with the photo that the owner uploaded.”

She soon received an AI match alert and learned that the cross street Grayson’s owner, Pam, had listed in her lost post was only a mile from her home. Missy contacted Pam right away.

That message changed everything. “I am sure that if we had not posted his picture and enabled the ability to match the images, we would never have known what happened to Grayson,” Pam said. “And we would not have connected with Missy.”

A long road for an aging cat

Grayson is almost 12 and has never lived outdoors. That made this reunion feel even more emotional, Pam said.

“I am still amazed at Grayson’s journey,” she added. “I look at him and cannot believe he made it through those 103 days. He is almost 12 years old, so he is not a young kitty.”

Pam said she still thinks about what those months were like for him. “[I] guess I will always wonder where he was and how many stops he made before he reached Missy’s loving home,” she said. “He must have known she would take care of him. It takes a special person to take the time to reunite a beloved pet with their family. Missy and her family went above and beyond to reunite us with Grayson.”

Why pet tech matters during the holidays

This season brings joy but also risks for pets. Visitors, travel and loud celebrations create more chances for animals to slip out or feel spooked. Tools like AI photo matching help families act fast when a pet goes missing. Love Lost connects shelters and neighbors in one place so that people like Pam and Missy can find each other.

What to do if your pet goes missing

Losing a pet can feel overwhelming, but taking fast action helps. These steps guide you through what to do right away.

1) Search your home and neighborhood right away

Look in closets, garages and under furniture. Walk your street and ask neighbors to check yards and sheds.

2) Upload your pet’s photo to Petco Love Lost

Take a clear photo and post it on the site. AI photo matching alerts you when a possible match appears. It also helps others contact you fast.

3) Visit your local shelters in person

Shelters update kennels throughout the day. Staff can guide you and help flag your pet’s profile. Go often until you get updates.

4) Post on local community groups

Use neighborhood apps, local Facebook groups and community forums. Include your pet’s photo, last known location and your contact info.

5) Put up flyers right away

Use a large photo and simple details. Place flyers at busy intersections and near schools, parks and businesses.

6) Contact your pet’s microchip registry

If your pet is microchipped, call the registry or log in to your account. Make sure the chip is registered to you, update your contact info and mark your pet as missing so shelters and vets can reach you fast.

7) Stay consistent with your search

Check Love Lost alerts often. Visit shelters and follow up on every lead. Persistence made the difference for Pam and Grayson.

How AirTags can help you find a lost pet faster

While tools like AI photo matching are invaluable after a pet goes missing, prevention and real-time tracking can make an enormous difference during the first critical hours. That’s where Apple AirTags come in. An AirTag isn’t a GPS tracker, but it can still be a powerful recovery tool when used correctly. When attached securely to your pet’s collar, an AirTag uses Apple’s vast Find My network. That network consists of hundreds of millions of nearby iPhones, iPads and Macs that can anonymously and securely relay the AirTag’s location back to you.

If your pet wanders into a neighborhood, apartment complex or busy area, the chances are high that another Apple device will pass nearby and update the location automatically. You won’t know who helped, and they won’t know it was them, but the location can show up on your map within minutes. For indoor cats or dogs that don’t usually roam far, this can be especially helpful. Even a rough location can narrow your search area and save precious time.

Important limits to know: AirTags work best in populated areas. They rely on nearby Apple devices, so coverage may be limited in rural or remote locations. They also don’t update continuously like true GPS pet trackers. That’s why AirTags should be seen as a backup layer, not a replacement for microchipping or dedicated pet trackers.

How to use an AirTag safely with pets

Use a secure, pet-specific AirTag holder that won’t break easily.
Attach it to a breakaway collar for cats and dogs to reduce injury risk.
Make sure Find My notifications are turned on so you get alerts quickly.
Combine it with microchipping and ID tags for the best protection.

Used together, these tools give you multiple ways to reconnect with your pet, whether minutes or months have passed.

TikTok ban: all the news on the app’s shutdown and return in the US

After briefly going dark in the US to comply with the divest-or-ban law targeting ByteDance that went into effect on January 19th, TikTok quickly came back online. It eventually reappeared in the App Store and Google Play as negotiations between the US and China continued, and Donald Trump continued to sign extensions directing officials not to apply the law’s penalties.

Finally, in mid-December, TikTok CEO Shou Zi Chew told employees that the agreements to create TikTok USDS Joint Venture LLC, which includes Oracle, Silver Lake, and MGX as part owners, have been signed, and the deal is expected to close on January 22nd, 2026. His letter said that for users in the US, the new joint venture will oversee data protection, the security of a newly-retrained algorithm, content moderation, and the deployment of the US app and platform.
