AI helped researchers bypass Apple M5 defenses
Apple devices have earned a reputation for being tough to break into. That comes from Apple’s tight control over the hardware, software and many of the protections standing between you and an attacker. However, a new claim from security startup Calif shows how quickly the cybersecurity world may be changing.
Calif says a small team of researchers used a preview version of Anthropic’s Claude Mythos to help build a working macOS kernel exploit against Apple’s new M5 chip protections in less than a week. A kernel exploit targets the core part of an operating system, which controls how your device runs and what apps can access.
The company says the exploit survived Apple’s Memory Integrity Enforcement, or MIE, a security feature designed to make memory-based attacks much harder on newer chips. The bigger concern is speed. Artificial intelligence may help skilled researchers find serious software flaws faster than ever before, which means scammers and cybercriminals could eventually use similar tools to find weak spots before companies have time to patch them.

Calif says its researchers built what it describes as the first public macOS kernel memory corruption exploit on M5 silicon with MIE enabled. The company says the attack targets macOS 26.4.1 on Apple M5 hardware.
It begins with a regular local user account and ends with root access. Root access gives someone the highest level of control on a Mac. That could let an attacker change system settings, reach sensitive files or run commands with powerful permissions.
That sounds alarming, but it needs context. Calif described this as a local privilege escalation chain. In everyday terms, an attacker would already need some way to get code running on the Mac first. This type of attack would more likely follow another step, such as a malicious download or compromised installer. Once bad code gets that first foothold, a privilege escalation bug can help it dig much deeper.

Memory corruption bugs have been a favorite target for attackers for years. These flaws can let attackers crash software, steal data or take over parts of a system.
Apple’s Memory Integrity Enforcement was designed to make that type of attack far more difficult. Apple says MIE uses hardware-assisted memory safety protections on A19 and M5 processors or later. In simpler terms, MIE helps the chip and operating system check whether software touches memory in suspicious ways. That makes many older attack tricks harder to pull off.
That is why Calif’s claim warrants attention. The researchers say they found a way around those protections with help from Mythos Preview. That suggests AI could speed up the hunt for flaws, even in systems with advanced built-in defenses.
AI CYBERSECURITY RISKS AND DEEPFAKE SCAMS ON THE RISE
Calif says Mythos Preview helped identify the bugs and assisted throughout exploit development. The company also made clear that human expertise still mattered.
According to Calif, Mythos found the bugs quickly because they belonged to known bug classes. However, bypassing Apple’s new protection required experienced researchers.
Think of it this way: AI helped point the researchers toward weak spots. People still had to understand how to turn those findings into a working exploit. That makes the story more concerning because AI may help skilled teams move much faster.
FORMER GOOGLE CEO WARNS AI SYSTEMS CAN BE HACKED TO BECOME EXTREMELY DANGEROUS WEAPONS
Mozilla has already seen similar potential. The organization said an early version of Claude Mythos Preview helped identify 271 vulnerabilities fixed in Firefox 150. Mozilla said those findings came during an evaluation of the model’s ability to help with security work.
So the bigger story goes beyond Apple. Advanced AI tools may give security researchers more speed. Those same tools could eventually help attackers search for software flaws faster, too.
Most people do not think about kernel exploits when they open up their laptops. They think about email, work and family photos. That is exactly why this story hits closer to home than it may seem.
If researchers can find high-impact bugs faster with AI, attackers may eventually try to do the same. The unsettling part is the speed. A flaw that once took months to discover might surface much sooner when AI helps scan code and suggest attack paths.
Calif called its work “a glimpse of what is coming.” That may sound dramatic, but the warning is easy to understand. Cybersecurity teams may need AI to defend systems as quickly as attackers use AI to search for weak spots.
MAC MALWARE MAYHEM AS 100 MILLION APPLE USERS AT RISK OF HAVING PERSONAL DATA STOLEN
This does not mean your Mac has suddenly become unsafe. Apple’s security model remains one of the strongest in consumer tech. It also does not mean MIE failed as a protection. No security feature blocks every attack forever.
DON’T IGNORE APPLE’S URGENT SECURITY UPDATE
However, updates now matter more than ever. Calif says it shared its findings with Apple and plans to release full technical details after Apple ships a fix. That is how responsible disclosure should work. Researchers report the issue first, the company investigates it, and users get a patch before attackers get a roadmap.
We reached out to Apple for comment, but did not hear back before our deadline.
That brings us to this: what you can do now to lower your risk.
10 SIMPLE CYBERSECURITY RESOLUTIONS FOR A SAFER 2026
You do not need to become a cybersecurity expert to lower your risk. A few smart habits can make it much harder for attackers to get the access they need.
Start with software updates. On your Mac, go to Apple menu > System Settings > General > Software Update. Install any available macOS updates. Also, turn on automatic updates where possible. This helps your Mac get important security fixes without waiting for you to remember.
Be careful with apps from links, pop-ups or unfamiliar websites. If an attacker needs code running on your Mac first, a fake app can become the front door. Download apps from the Mac App Store or directly from trusted developers. Also, pause before opening installers sent through email or social media links. Strong antivirus software can add another layer of protection by helping detect malicious downloads, suspicious links and scam websites before they put your Mac at risk. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.
Review which apps have access to sensitive parts of your Mac. Go to Apple menu > System Settings > Privacy & Security and check permissions for areas such as Accessibility, Camera, Microphone and Screen Recording. Remove access for apps you do not recognize or no longer use. These permissions can give apps powerful reach across your device.
Turn on two-factor authentication (2FA) for your Apple Account. This adds another layer of protection if someone steals or guesses your password. Also, use a strong, unique password. Do not reuse the same password you use for email or banking. A password manager can help create and store unique passwords for each account, so you do not have to remember them all yourself. Check out the best expert-reviewed password managers of 2026 at CyberGuy.com.
Your browser is one of the most common places where attacks begin. Keep Safari, Chrome, Firefox or any other browser updated. Then, review your browser extensions. Remove anything you do not use or do not recognize. A shady extension can track your activity, inject ads or collect sensitive data.
Safari: Open Safari > Settings > Extensions. Uncheck any extension you do not recognize or select it and click Uninstall. Safari extensions update automatically with their apps.
Chrome: Open Chrome > three dots > Help > About Google Chrome to check for updates. To review extensions, go to Chrome > three dots > Extensions > Manage Extensions. Remove anything suspicious or unnecessary.
Firefox: Open Firefox > Firefox menu > About Firefox to check for updates. To review add-ons, go to Firefox > Add-ons and themes > Extensions. Remove anything you do not recognize. Firefox recommends keeping add-ons set to update automatically.
Scammers love fake pop-ups that claim your Mac has a virus. These alerts often push you to download software or call a fake support number. Do not click the warning or call the number on the screen. Close the tab or quit the browser. If you feel unsure, restart your Mac and check for updates through System Settings.
Use Time Machine or another trusted backup method. A recent backup can help you recover if malware damages files or locks you out. Keep at least one backup separate from your Mac. That way, a device problem does not take your backup down with it.
Many people leave their Macs running for weeks. A restart can help clear temporary processes and apply pending updates. A restart will not solve every security problem, but it can help your Mac finish updates and clear out processes that no longer need to run.
FBI WARNS OVER 1 MILLION ANDROID DEVICES HIJACKED BY MALWARE
Apple built serious protections into its newest chips, and that still matters. But Calif’s claim shows that even the strongest consumer security systems now face a new kind of pressure. AI is starting to change the speed of vulnerability research. For you, the lesson is this. Keep your Mac updated. Be careful what you install. Review the apps that have deep access to your system. The age of “set it and forget it” security is fading fast. Your device may be smart, but the tools looking for its weak spots are getting smarter too.
If AI can help a small team challenge Apple’s newest defenses in days, should companies be required to disclose how they are using AI to find and fix security flaws before attackers do? Let us know by writing to us at CyberGuy.com.

BREAKING: US Diplomat Found Dead
An American diplomat assigned to the U.S. Embassy in Myanmar has been found dead under mysterious circumstances, prompting a murder investigation that has already led to charges against a Thai national in the military-ruled Southeast Asian nation.
The State Department confirmed the death of the embassy employee but has remained tight-lipped about the details surrounding the case, citing privacy concerns for the diplomat’s family and loved ones.
“Out of respect for the privacy of the family and loved ones, we have no further information to provide at this time,” the State Department said in an emailed reply to questions from The Associated Press.
American officials stationed in neighboring Thailand, along with representatives from the U.S. Embassy in Myanmar, referred all inquiries back to the State Department, underscoring the sensitivity of the investigation and the limited public information that has been released so far.
According to members of Myanmar’s diplomatic community, the diplomat was discovered dead on May 11 at the Sakura Residence & Hotel in Yangon. The property serves as a long-term residence for diplomats, foreign business executives, aid workers, and other international visitors. Located roughly one mile from the U.S. Embassy, the hotel has long been considered a secure location frequently used by members of the diplomatic corps.
The circumstances surrounding the diplomat’s death remain unclear, and authorities have provided few public details about what investigators believe occurred inside the residence.
However, significant developments emerged this week when a Thai woman appeared in court and was formally charged in connection with the case. According to two attorneys familiar with the proceedings, the woman faces a murder charge as well as a separate immigration-related offense under Myanmar law.
If convicted, the penalties could be severe. Under Myanmar’s legal system, a murder conviction can carry a sentence ranging from 10 years in prison to life imprisonment or even the death penalty, depending on the circumstances of the case and the court’s findings.
Thailand’s Foreign Ministry confirmed that it has been providing consular assistance to the accused woman and has notified her family about the case. Officials declined to comment further on the allegations or the evidence being presented by prosecutors.
The case is unfolding against the backdrop of ongoing instability in Myanmar, which has been engulfed in political turmoil and armed conflict since the military seized power in a 2021 coup that ousted the democratically elected government of Aung San Suu Kyi.
Since then, the ruling military junta has faced growing resistance from pro-democracy groups, ethnic militias, and armed opposition forces. The conflict has expanded into a nationwide civil war that has left thousands dead and displaced millions, while drawing international condemnation from Western governments, including the United States.
The country’s military government maintains strict control over information, making independent reporting and transparency difficult. Authorities rarely release detailed information regarding criminal investigations, particularly those involving foreign nationals or diplomatic personnel.
Consistent with that pattern, police officials, prison authorities, and court representatives have all declined to publicly discuss the case involving the American diplomat. No official explanation has been provided regarding the cause of death, potential motives, or evidence supporting the charges against the Thai woman.
For now, many questions remain unanswered. U.S. officials have offered little information beyond confirming the diplomat’s death, while Myanmar authorities continue to conduct their investigation largely behind closed doors.
As the case moves through Myanmar’s judicial system, American officials, members of the diplomatic community, and the diplomat’s family are awaiting further answers about what led to the death of a U.S. government employee serving overseas in one of the world’s most volatile regions.

Supreme Court Delivers Landmark Midterm Decision With 6-1 Ruling
Florida Republicans notched a major victory this week after the Florida Supreme Court handed Gov. Ron DeSantis and GOP lawmakers a significant legal win, ruling that the state’s newly drawn congressional map will remain in place for the 2026 midterm elections.
In a decisive 6-1 ruling, the court rejected an emergency effort by left-leaning voting-rights organizations seeking to block the map before voters head to the polls this fall. The decision ensures that Florida’s elections will proceed under the congressional districts approved by the Republican-controlled Legislature during a special session earlier this year, bringing much-needed certainty to the state’s electoral process.
The legal challenge was brought by the Equal Ground Education Fund and several allied groups, which claimed the map was drawn to benefit Republicans and therefore violated Florida’s Fair Districts Amendment. That amendment, approved by voters in 2010, prohibits lawmakers from intentionally drawing districts to favor or disadvantage a political party.
The plaintiffs sought an injunction that would have prevented the map from taking effect while their broader lawsuit continued through the court system. However, Florida’s highest court declined to intervene.
Writing for the majority, the court emphasized that the case should proceed through the normal judicial process before the Supreme Court becomes involved.
“At this time, we do not have jurisdiction over that matter,” the majority opinion stated.
The justices further made clear that they would not assume future rulings from lower courts would automatically warrant Supreme Court review, signaling a commitment to allowing the judicial process to play out as designed.
The ruling provides stability for Florida voters, election officials, and candidates as the election season rapidly approaches. With candidate qualifying deadlines looming and election preparations already underway, the court’s decision removes uncertainty that could have disrupted the electoral process.
Justice Jorge Labarga was the lone dissenter.
Labarga argued that the court should have immediately stepped in because of the statewide significance of the dispute and the fast-approaching election calendar.
“Unfortunately, for now, and with a filing deadline and an election fast approaching, we will not have the opportunity to review the issues of statewide importance raised in the petitioners’ efforts to enjoin Florida’s 2026 congressional map,” Labarga wrote.
Notably, Labarga remains the only member of the Florida Supreme Court who was not appointed by a Republican governor.
The decision marks yet another victory for DeSantis, who has consistently argued that Florida’s congressional districts should comply with recent federal court rulings limiting the use of race in redistricting decisions. The governor has maintained that districts drawn primarily around racial considerations face increasing constitutional scrutiny and should be revisited to ensure compliance with federal law.
Following those court rulings, DeSantis pushed for changes to portions of Florida’s congressional map that had previously been crafted with race-based considerations in mind. Rather than waiting for lawmakers to formulate a proposal, the governor’s office took an active role in developing a new map.
Jason Poreda, an aide to DeSantis, drafted the congressional plan that was ultimately presented to lawmakers. Republican legislators later adopted the proposal without making changes, reflecting strong support for the governor’s approach.
Predictably, Democrats and voting-rights activists immediately objected to the new districts, citing testimony regarding partisan voting data and public statements discussing potential Republican advantages under the map. Supporters of the plan countered that the changes were driven by evolving legal standards and recent court decisions, not partisan considerations.
Florida’s 28 congressional seats make it one of the nation’s most influential political battlegrounds. Republicans believe the new map could help solidify the party’s position in the state and strengthen efforts to maintain or expand the GOP majority in the U.S. House of Representatives.
The Florida case is part of a larger national battle over congressional redistricting as states across the country grapple with court rulings that continue to reshape election law. Republicans have increasingly argued that district maps should be based on constitutional principles and equal representation rather than race-based political engineering.
While the underlying lawsuit remains active and could continue through Florida’s courts, the Supreme Court’s decision ensures that the 2026 elections will move forward under the current map.
Justice Adam Tanenbaum highlighted that point in a separate concurring opinion, emphasizing the importance of certainty as election season nears.
“The people of Florida can rest assured that elections will take place this year,” Tanenbaum wrote.
His statement underscored what many Republicans view as the central takeaway from the ruling: Florida voters now have clarity, election officials can move forward with confidence, and the state’s democratic process can proceed without last-minute judicial interference.

The Moment Trump Supporters Have Waited For — Happens At 4pm
Here’s a rewritten version in a more engaging, conservative news style:
President Donald Trump signaled Thursday that his patience with Iran has run out, declaring there will be “no more negotiation” after accusing the regime of dragging out talks while continuing to resist U.S. demands.
During an appearance on Fox & Friends, Trump said Iran has squandered multiple opportunities to reach an agreement and warned that the United States remains prepared to increase pressure if Tehran refuses to comply.
“Well, that could happen if we want to keep going,” Trump said when asked about reports that Iran had been given a final ultimatum. “And the deal is a very good deal. The problem with the deal — it could be the greatest deal in history. They could wave the white flag of surrender.”
The president mocked media coverage that he believes has downplayed Iran’s deteriorating military position.
“‘We surrender. We’re finished. Praise be to Allah,’” Trump said, describing what he believes would be required before some outlets would acknowledge a U.S. victory. “And they could do all of this loud and clear, and the fake news would say it was a great victory for Iran.”
Trump then painted a grim picture of Iran’s military capabilities, claiming U.S. operations have crippled much of the country’s defensive infrastructure.
“We’re killing them. They have no navy. No air force. No anti-aircraft,” Trump said. “We are flying planes over the middle of Tehran and they don’t have any idea.”
According to Trump, U.S. actions have severely damaged Iran’s radar systems, missile launchers, drone capabilities, and air defenses.
“We’ve knocked out all their radar, all of their anti-aircraft, much of their missiles — probably less than 20%,” he said. “Most of their launchers, the missile launches, which is quite important. Their drone capacity is way down. Their attacks are very minor. They’re finished.”
The president also blasted major media outlets for what he described as misleading coverage of the conflict.
“And yet the fake news — just like with the election — the fake news is out there saying, ‘Wow, Iran is doing just so well. Trump is doing terribly,’” he said.
Trump specifically singled out MSNBC host Joe Scarborough, saying he recently watched a portion of Morning Joe and was stunned by the program’s portrayal of events.
“I watched it yesterday, one of his shows for five minutes,” Trump said. “This fake Joe Scarborough talking about how well Iran is doing. Where did that come from? It’s just the craziest thing.”
Despite Trump’s tougher rhetoric, Fox News anchor Bret Baier reported Wednesday that the president remains cautiously optimistic that a diplomatic resolution is still possible.
“I talked to him today, and there was this sense of optimism — cautious optimism — that they maybe get to a deal soon,” Baier said during America Reports.
At the same time, tensions remain high. Baier noted that Iranian state media announced a new authority intended to regulate traffic through the Strait of Hormuz, one of the world’s most critical shipping routes. The proposal would require vessels to obtain authorization before crossing the strategic waterway, a move likely to face resistance from the international community.
Additional details emerged Wednesday regarding recent U.S. military operations. Fox News correspondent Trey Yingst revealed that Trump personally contacted him from the Situation Room shortly before American forces launched another wave of strikes against Iranian military targets.
According to Yingst, the president described the operation before it began, underscoring the administration’s confidence in its military strategy.
Following the strikes, Trump took to Truth Social to deliver a blunt assessment of Iran’s condition.
“Iran’s Military is a complete and total mess,” the president wrote.
With negotiations appearing increasingly fragile and military pressure intensifying, the coming days could prove decisive in determining whether Iran returns to the negotiating table—or faces even greater consequences from the United States.
