Last month, several news outlets reported that Russia could be planning to deploy a space-based nuclear weapon, alarming, well, pretty much everyone.

Nuclear weapons in space are bad news for the entire planet

US policy hawks, space environmentalists, and anyone with a lingering memory of Cold War-era fears over nuclear annihilation were all sounding the alarm about the threat posed by a Russian nuke in space.
As scary as the prospects sound, the US government has assured people that the weapon doesn’t necessarily pose a threat to people on the ground. Instead, it would target other objects in space, like the satellites used by the US military for communications and other operations.
But that struck some as cold comfort, especially given Russian President Vladimir Putin’s unpredictability. And Putin has indicated that putting a nuclear power unit in space is a priority for the country.
In the long term, defense experts warn that having a nuclear weapon positioned in space could pose a threat to life on Earth by eroding international relations and space law. From clouds of space debris that could cut off access to space to the development of weapons that could launch from space to hit targets on the ground, space-based nukes have the potential to impact everything — and everyone.
Anti-satellite weapons already exist — but not nuclear ones
No country has ever used an anti-satellite weapon against another country, but several countries have destroyed their own satellites in demonstrations of their military capabilities — including the US, Russia, China, and India.
These tests are not without controversy: a 2021 Russian test of an anti-satellite weapon, for example, drew condemnation from NASA for creating debris that threatened astronauts on the International Space Station (including Russian cosmonauts). Since then, a UN panel has called for a ban on the testing of such weapons and several European Union nations and the US have pledged not to perform destructive tests.
A nuclear weapon in space would cause much more destruction than previous anti-satellite weapons tests, explained Andrew Reddie of the Berkeley Risk and Security Lab, as existing space-based weapons typically destroy just one satellite at a time. In the age of huge satellite constellations such as Starlink, knocking out a single satellite is more of an annoyance than a major threat.
To destroy satellites at scale, you need a different weapon, such as a directed energy weapon based on the ground. Or, you could use a nuclear weapon in space, which creates not only shock effects but also heat, radiation, and an electromagnetic pulse — giving it the ability to take out or impair entire networks.

International laws protecting space
The best response the international community has had to date in restricting the stockpiling and use of nuclear weapons is international law. When it comes to space, the key piece of legislation is the Outer Space Treaty of 1967, of which Article IV prohibits placing nuclear weapons or other weapons of mass destruction in orbit.
Detonating a weapon in space would be unprecedented and could run afoul of international rules barring the use of indiscriminate weapons on civilians or civilian objects.
“It seems to be that any kind of destruction of something in space is an indiscriminate weapon, and indiscriminate weapons are prohibited, and the use of indiscriminate weapons are a war crime,” said Christopher Johnson, professor of law at Georgetown University.
However, this assumes that satellites are being destroyed by a kinetic impact. It might be possible to disable or jam satellites in another way, such as using an electromagnetic pulse, or EMP. Some reports have suggested that Russia is developing an EMP anti-satellite weapon rather than a nuclear one. If that could be done in a way that doesn’t create a debris field, that may not contravene the international law because it would no longer be a weapon of mass destruction or indiscriminate in its effects.
With the current situation, “We don’t know what is being threatened,” Johnson said and pointed out that the details matter a lot here and that Russia is capable of a very close reading of the relevant laws to stay within them.

The cascading debris problem
The reason that the use of weapons in space could be considered indiscriminate is because of the debris field they create. Destruction of objects in space creates large pieces of debris, which are hazardous but relatively easy to track. Where it gets dangerous is the increasing number of medium and small pieces of debris, which are too small to be trackable but are still traveling at high enough speeds to do tremendous damage to other objects or even people in space.
“A fleck of paint the size of your thumbnail can go through most spacecraft. Traveling at a very high velocity — 18,000 mph — it’ll go right through it,” said space debris expert Vishnu Reddy of the University of Arizona.
A serious collision in orbit could create a field of small debris pieces that would quickly collide with other satellites, creating a cascade. At a critical mass, each collision creates more debris, which creates more collisions, which creates more debris, until an entire orbit becomes difficult or impossible to access.
This scenario, known as the Kessler syndrome, could cut off access to space for generations: from making rocket launches more difficult, dangerous, and expensive to, at worst, making any kind of space travel completely impossible for decades and shutting humanity off from the stars.
This concept of the syndrome was first proposed in the late 1970s, when there were optimistic predictions that the Space Shuttle might fly as often as once per week. That never came to fruition, so in the intervening decades, there was less concern about the possibility of a cascading debris event.
But now, with the pace of both government and private launches ramping up to the highest levels ever, space debris is once again on everyone’s radar, Reddy said: “The old fear has come back.”
“A fleck of paint the size of your thumbnail can go through most spacecraft.”
Vulnerable orbits
The most useful orbits around the planet are getting increasingly crowded, and even if humanity stopped launching things into space tomorrow, the debris already in orbit would continue to collide and make the problem worse.
Over the long term, if this problem isn’t addressed, it could spiral into a Kessler syndrome, as the situation can go from bad to catastrophic quickly. “The timeline for the cascading collisional scenario is very short,” Reddy said. “We’re talking anywhere from hours to days to weeks, not months to years to decades.”
The use of a nuclear weapon in orbit, depending on its size and in which orbit it is detonated, could kick off such a cascading scenario. But this isn’t exclusive to nuclear weapons. It’s possible that a bad actor destroying a single, carefully chosen satellite could create a cascade, Reddy said, if they picked a vulnerable target.
In geostationary orbit, for example, there are only so many slots available for satellites in the ring around the Earth’s equator. That makes the slots in high demand, as they are a limited resource. And this scarcity is compounded by the fact that it’s very difficult to remove debris from an orbit so distant, at over 20,000 miles from the Earth’s surface. If these slots are blocked by debris, it could cut off functionality for systems like communications satellites, weather satellites, and navigation satellites.
“That would be really, really bad,” Reddy said. “One satellite explosion big enough would be enough to destroy a lot of assets in geostationary orbit.”
Fears for the future
Although it’s unlikely that any actor would launch a nuclear weapon in space with the specific intention of kicking off a cascading debris effect, it might happen as a consequence of trying to destroy a particular military system. But the debris isn’t the only thing that has experts worried.
Security risk expert Andrew Reddie questioned what it would take to convert the technology for a nuclear anti-satellite weapon into a platform that could deploy nuclear weapons from space to targets on the ground. This would require a reentry vehicle, for example, which doesn’t exist yet but could theoretically be constructed based on existing technology. Nukes launched from space would give less warning time than those launched from the surface, threatening thousands or even millions of people.
It’s not that the deployment of nukes in space is necessarily likely, with no current indication that Russia is developing such a weapon. But it does show how nuclear weapons in space could shift the geopolitical landscape dramatically and why reports of potential space-based nuclear weapons have drawn such condemnation.
“The old fear has come back.”
A matter of global governance
Russian President Vladimir Putin has denied any plans to develop a nuclear anti-satellite weapon and has said that Russia is against the deployment of nuclear weapons in space. And experts agree that Russia takes pride both in its space program and in its role in international governance as a permanent member of the United Nations, though the invasion of Ukraine has shaken the country’s international status and resulted in the suspension of joint space missions with other space agencies.
For the Russians to develop or deploy such an anti-satellite weapon “would undermine their diplomatic efforts,” Johnson said. Russia has a global leadership role in space governance and was a key negotiator in the Outer Space Treaty, and going against that would be self-undermining. “They take their role seriously,” Johnson said.
There is also international pressure from beyond the US and Europe. Even China, which has a space program that is notably separate from other nation’s space programs and does not participate in international projects like the International Space Station, has emphasized that it is against the proliferation of weapons in space. US government representatives are trying to recruit China and India in discouraging Russia from pursuing nuclear anti-satellite technology.
Deploying a weapon in space would be against Russia’s own self-interest, experts argue. Spreading a debris field across an entire orbit limits the ability of everyone to access space, including those who fired the weapon.
However, those effects are not necessarily symmetrical. “The Americans rely on space far more than both Russia and China, so in most domains, if you were to degrade it for everybody, that would be a problem,” Reddie said. “But if you’re degrading space, it’s going to asymmetrically affect the Americans. And the Russians know that.”
This raises the question of what the global consequences might be if — or when — any nation chooses to use a space-based weapon and whether the existing international legal structure could respond to that.
Space debris expert Reddy compared firing such a weapon to flipping a chess board when you’re losing a game: “It’s no longer about winning. It’s ‘I’m losing, so nobody wins.’”

Microsoft’s Office 2019 apps for Mac will stop working next month, because the company isn’t renewing a certificate that validates Office licenses. Owners of Office 2019 for Mac are being warned they’ll have to purchase Office 2024 or a Microsoft 365 subscription if they want to continue editing documents.
Microsoft previously promised that “all your Office 2019 apps will continue to function,” when it announced end of support in 2023. The company then quietly updated that support note last month to remove the mention of apps continuing to function, replacing it with “Rest assured that all your Office 2019 apps won’t lose any data.”
Starting on July 13th, Office 2019 for Mac and Office 2021 for Mac will both run in “reduced functionality mode,” allowing people to open files but not edit, save, or create new documents. The reduced functionality will impact Word, Excel, PowerPoint, Outlook, and OneNote.
While Microsoft is providing a certificate update for Office 2021 as it’s still supported until October 13th, 2026, the company is leaving Office 2019 for Mac users out in the cold as support for these apps ended a few years ago. “Office 2019 for Mac reached end of support on October 10, 2023, and no longer receives updates,” says Microsoft. “Because Office 2019 cannot be updated to the required version, this issue cannot be resolved by updating or reinstalling Office 2019 for Mac.”
JimmyTech points out that old versions of Microsoft 365 apps on Mac and iOS will also be affected by this certificate issue, but a simple update will fix it for those users.
Microsoft regularly ends support of software and there’s always the risk you could run into issues running older apps or versions of Windows. It’s still surprising to not see Microsoft make an exception here though, particularly because this certificate issue breaks the main functionality of an app you’ve paid a one-time license fee for.

You know that little moment when your phone rings and the name on the screen makes you drop everything?
Maybe it says your spouse, your daughter, your boss or your best friend. You answer because you trust the name. Then the voice sounds familiar too.
That is exactly what makes the latest phone scams so dangerous.

Scammers no longer have to call from a strange number. They can spoof a trusted contact’s phone number. Then they can use AI voice tools to sound like someone you know. Android is now rolling out a new feature called fake call detection to help warn you when that familiar call may be a fake.

What is Android fake call detection?
Android fake call detection is a new protection built into Phone by Google. It is designed to spot suspected spoofed calls when both people on the call use Phone by Google.
Think of it as your phone quietly asking, “Is this call really coming from that person’s device?” If the answer looks suspicious, your phone can show a warning and advise you to hang up. That small alert could stop a scam before fear, panic or confusion takes over.
ANDROID SECURITY UPGRADES OUTSMART SCAMS AND PROTECT YOUR PRIVACY
How Android fake call detection works
The feature works automatically in the background. You do not need to answer a quiz, scan a code or press a button during the call. When a trusted contact calls you, their phone sends a silent confirmation signal to your phone. That signal helps prove the call really came from their device.
If a scammer spoofs your contact’s number, that confirmation signal may be missing. Your phone then checks with your contact’s actual device. If the real device says it is not placing a call, your screen can warn you that the call may be fake.
The system uses end-to-end encrypted RCS technology, so the check happens privately. You can also turn the feature off in Phone by Google settings.

Why fake calls are getting harder to spot
For years, caller ID gave people a sense of control. If the name looked familiar, most of us felt safer picking up. That old habit now works in the scammer’s favor.
Scammers can use internet-based calling tools to spoof numbers. That means your phone may display the name of someone you trust, even though the call comes from somewhere else.
Then comes the AI voice trick. With today’s audio tools, scammers can make a fake voice sound shockingly real. They may pretend to be a family member in trouble, a bank employee warning about fraud or a manager asking for urgent help.

That combination makes the call feel personal and immediate. It also makes you more likely to act before you think.
Why Android is adding this protection now
Impersonation scams have become a major global problem. INTERPOL’s March 2026 Global Financial Fraud Threat Assessment cited impersonation fraud as one of the leading contributors to more than $400 billion in global losses.
In the U.S., impersonation scams remain one of the top fraud categories reported to the FTC. Losses reached $2.95 billion in 2024.

Those numbers tell you why this feature deserves attention. Scammers go where the money is. Right now, they know trusted voices and trusted names can open the door.
Which Android phones get fake call detection?
Google says fake call detection is rolling out globally in Phone by Google this month, starting with Pixel devices.
The feature is available on Android 12 and newer devices with Phone by Google, Contacts and Google Messages installed. It also requires RCS capability in Google Messages.
SAMSUNG MESSAGES ENDING? WHAT ANDROID OWNERS MUST KNOW
There is one key limitation. Both you and the person calling you must use Phone by Google for fake call detection to work.
Phone by Google already comes as the default phone app on many Android devices. If your phone uses a different calling app, you can install Phone by Google from the Play Store and set it as your default phone app.
How Android fake call detection protects you
This feature gives you an extra warning at the exact moment you need it most. That timing is important. Scam calls often rely on emotion. The caller may say someone got arrested, a loved one had an accident or a bank account faces an urgent threat.
SSA IMPERSONATION SCAMS ARE GETTING MORE PERSONAL
When the voice sounds familiar, your guard drops. A warning on your screen can interrupt that emotional rush. It gives you a reason to stop, hang up and verify the story another way.
What Android fake call detection cannot do
This new tool helps, but it cannot protect you from every scam. It may not work if the other person does not use Phone by Google. It also may not cover calls from businesses, unknown numbers or contacts using unsupported devices. So you still need basic scam rules.
If someone asks for money, gift cards, crypto, account codes or remote access to your device, hang up. Then call the person or company back using a number you already trust.
Also, never stay on the line just because the caller tells you to. That is one of the oldest pressure tactics in the scammer playbook.

How to protect yourself from AI voice scams
AI voice scams work because they sound personal, urgent and believable, so your best defense is to slow the conversation down before you act.
1) Create a family safe word
Pick a simple word or phrase that only your close family knows. It should be easy to remember but hard for a scammer to guess. Then, if someone calls with an emergency and asks for money, ask for the safe word. If they cannot give it, hang up and verify the story another way.

2) Pause when the call feels urgent
Scammers want you scared because fear makes people act fast. That is why fake emergency calls often sound intense, emotional and rushed. Take a breath before you do anything. A real loved one, bank or employer will let you verify what is happening.
3) Call back using a trusted number
If a call feels suspicious, hang up. Then call the person back using a number saved in your contacts or one you know is real. Do not use a number, link or instruction the caller gives you. That could send you right back to the scammer.
4) Never send money or codes during the call
Do not send gift cards, crypto, wire transfers or payment app transfers because a caller sounds convincing. Also, never share a one-time passcode, PIN or account login code over the phone. Once scammers get that information, they can move fast.
5) Turn on scam protections on your phone
Use the built-in protections already available on your device. Pixel and Samsung users can enable Scam Detection in the Phone by Google app to help flag suspicious calls. Also, consider using strong antivirus software that includes AI-powered scam protection to help detect scams in texts, online content and deepfake videos. Keep an eye on call warnings too. If your phone tells you something looks risky, treat that alert seriously. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
6) Keep your phone apps updated
Update Phone by Google, Google Contacts and Google Messages when updates are available. These tools work best when your apps and phone software stay current. Updates often include security improvements, bug fixes and new scam protections.
Here’s how to check for updates on Android:
- Open the Google Play Store app.
- Tap your profile icon in the top right corner.
- Tap Manage apps & device.
- Under Updates available, tap See details.
- Look for Phone by Google, Google Contacts and Google Messages.
- Tap Update next to each app, or tap Update all.
You can also turn on automatic app updates by opening the Google Play Store app, tapping your profile icon, then going to Settings > Network preferences > Auto-update apps. From there, choose whether to update apps over Wi-Fi, over Wi-Fi or mobile data, with limited mobile data or not at all.

Android’s fake call detection is a smart step in the fight against AI-powered phone scams. It recognizes something many people already know: the name on your caller ID no longer proves the person calling you is real. This feature gives Android users another layer of protection when scammers try to hijack trust. Still, the safest move remains simple. Slow down, verify the call and never let panic make the decision for you.

Congress narrowly voted to fund President Donald Trump’s mass deportation agenda, giving the Department of Homeland Security $70 billion over the next three years.
The house voted 214 to 212 in favor of the reconciliation bill Tuesday, following the Senate’s 52-47 vote last Friday morning. The vote fell largely along party lines. Sen. Lisa Murkowski (R-AK) was the only Senate Republican to vote against it. Rep. Tim Walberg (R-MI), initially voted against the bill — meaning it would have failed — but changed his vote after huddling with House Majority Leader Steve Scalise (R-LA) and Appropriations Chair Tom Cole (R-OK), according to The Hill. No Democrats voted in favor of the funding bill, which was done through a budget reconciliation process to avoid a Democratic filibuster.
In a speech on the House floor ahead of the Tuesday vote, Rep. Mary Gay Scanlon (D-PA) criticized Republicans for using the budget reconciliation process to avoid negotiating with Democrats, and emphasized ICE’s lack of popularity with the American people.
“At its core, this Republican reconciliation budget bill is a statement about priorities, and the priorities represented in this budget bill could not be more out of step with the needs and values of the American people,” Scanlon said.
Scanlon noted that DHS has yet to spend $100 billion of the nearly $200 billion it received under Trump’s One Big Beautiful Bill Act. She added that Trump has not only expanded ICE’s reach by increasingly going after legal immigrants but also weaponized DHS against its critics. The bill, she said, will “supercharge” Trump’s abuses.
After the House markup last Friday, Rep. Rosa DeLauro (D-CT), ranking member of the House Appropriations Committee, noted that the bill not only lacks sufficient reforms but also cuts funding for cybersecurity and TSA, whose workers went weeks without pay during the DHS shutdown.
The funding bill comes at a time of deep unpopularity for ICE. One recent poll found that just 33 percent of voters approve of how the agency is doing its job.
And it comes amid yet another threat from border czar Tom Homan to flood New York City with ICE agents. In an interview with Fox News on Monday, Homan said he would send “more ICE agents than you’ve ever seen” to New York City if the state government passed a bill limiting cooperation with DHS.
“Providing a quarter trillion dollars to an administration promising that the public ‘ain’t seen shit yet’ when it comes to mass deportation is a historic mistake,” Todd Schulte, president of the immigration reform group FWD.us, said in a statement. “Supercharging the funding for these already out of control systems will come with terrible human consequences and continue to be met with increasing opposition from voters.”
Correction, June 9th: A previous version of this story said Rep. Tim Walberg voted against the funding bill. He initially voted against it but then changed his vote to support it.
Update, June 9th: This story has been updated to include comment from FWD.us president Todd Schulte.
