Microsoft issues emergency updates for zero-day SharePoint flaws. 

Hackers exploited two zero-day flaws in Microsoft SharePoint, launching a global cyberattack that hit U.S. federal and state agencies, universities, energy firms, and international entities. The attacks targeted on-premise SharePoint servers, not Microsoft 365. These vulnerabilities, CVE-2025-53770 and CVE-2025-53771, enabled remote code execution and were exploited in “ToolShell” attacks, bypassing previous patches. Microsoft has issued emergency updates for SharePoint Subscription Edition and 2019, with a patch for 2016 still pending.

Despite early mitigation advice, many servers remain vulnerable. Hackers accessed sensitive data and cryptographic keys, allowing potential reentry even after patching. At least 50 breaches have been reported, including U.S. government and European agencies. The FBI, CISA, and international partners are investigating.

Security experts warn that simply patching isn’t enough, admins must rotate machine keys and check for signs of compromise. 

Alaska Airlines resumes operations following an IT outage. 

Alaska Airlines grounded its fleet due to an unspecified IT outage on the evening of July 20, temporarily halting all Alaska and Horizon Air flights. The issue lasted about three hours, with operations resuming by 11 p.m. Pacific. While the airline hasn’t detailed the cause, recent airline-targeted cyberattacks raise concerns, with the Scattered Spider gang a possible suspect. Although most flights were grounded, the late-night timing meant fewer scheduled departures. Alaska warned of ongoing delays as it works to restore normal operations.

The UK government reconsiders demands for Apple iCloud backdoors. 

The UK government is reconsidering its demand that Apple provide access to encrypted iCloud data, amid pressure from the Trump administration and U.S. Vice President JD Vance. In January, the Home Office ordered Apple to create a backdoor under the UK’s Investigatory Powers Act, but U.S. officials warn this could threaten tech partnerships and privacy rights. Apple withdrew its most secure cloud service from the UK and is challenging the order in court, joined by WhatsApp. The move has sparked a major encryption battle and drawn criticism from both the U.S. government and privacy advocates. UK officials admit the Home Office mishandled the situation and now face internal disagreement over how to proceed. The Labour government, focused on digital trade and AI, is wary of provoking U.S. leaders, who see the issue as a threat to free speech and international data agreements.

A French Senate report raises concerns over digital sovereignty. 

A French Senate report has criticized the government’s growing reliance on U.S. tech giants, especially Microsoft, warning it compromises national digital sovereignty and exposes public data to U.S. surveillance laws like FISA and CLOUD. Despite previous warnings, France continues outsourcing critical IT systems to American firms, including a €74 million deal for the education sector. Officials admit French data hosted by Microsoft cannot be guaranteed safe from U.S. authorities. Critics, including MP Philippe Latombe, blame bureaucratic inertia and the dismissal of European alternatives as too costly. A 2025 report revealed Europe sends €265 billion annually to U.S. tech firms, fueling American jobs while weakening EU independence. While countries like Denmark are shifting to open-source solutions, EU institutions are slow to act. The European Parliament has called for stronger digital sovereignty, noting U.S. firms control 69% of Europe’s cloud market and store most Western data.

Meta declines to sign the EU’s new voluntary AI code of practice. 

Meta has declined to sign the EU’s new voluntary AI code of practice, warning it creates legal uncertainty and overreaches the upcoming AI Act’s scope. The code aims to guide companies in complying with AI rules before they take effect on August 2nd. Meta argues the regulation could hinder innovation and harm European tech competitiveness. OpenAI, by contrast, has agreed to sign. Meta’s stance reflects growing tension between the EU’s strict regulatory approach and the U.S.’s more hands-off, pro-industry stance under the Trump administration.

A new report claims last year’s CrowdStrike outage disrupted over 750 hospitals. 

A year after a faulty CrowdStrike software update triggered mass computer crashes, new research reveals the incident disrupted at least 759 U.S. hospitals, more than 200 of which lost access to patient-critical systems like health records and fetal monitors. The UCSD-led study warns the event was a potential public health crisis, drawing comparisons to major cyberattacks. Though most services recovered within six hours, researchers stress even short delays in care can harm patients. CrowdStrike disputes the findings, blaming possible overlap with a Microsoft Azure outage and calling the research flawed. However, the study suggests the true impact may be underestimated, as only one-third of U.S. hospitals were scanned. Researchers argue the breadth of the outage and its potential health risks show the need for better preparedness and real-time visibility into hospital IT failures, whether from bugs or cyberattacks.

The World Leaks extortion group has breached Dell’s Customer Solution Centers. 

The extortion group “World Leaks,” formerly known as Hunters International, has breached Dell’s Customer Solution Centers, environments used for product demos and testing. Dell confirmed the attack but emphasized that the affected platform is isolated from core systems and does not handle real customer data. The stolen data is believed to be synthetic or publicly available, with only a dated contact list considered legitimate. World Leaks, which pivoted from ransomware to pure data extortion in early 2025, has claimed nearly 50 victims so far but has not publicly listed Dell. The group has also exploited outdated SonicWall devices in other attacks. Dell declined to reveal how the breach occurred or details about ransom demands, stating the incident is still under investigation. The event highlights the evolving tactics of extortion gangs focusing on data theft rather than encryption.

Hewlett-Packard Enterprise (HPE) issues a critical warning about two severe security flaws in Aruba Instant On Access Points. 

Hewlett-Packard Enterprise (HPE) has issued a critical warning about two severe security flaws in Aruba Instant On Access Points, used widely by small to medium businesses. The primary flaw, CVE-2025-37103, involves hardcoded admin credentials in firmware versions 3.2.0.1 and earlier, allowing remote attackers to bypass authentication and gain full web interface access. A second flaw, CVE-2025-37102, enables command injection via the Command Line Interface (CLI) but requires admin access, making it chainable with the first vulnerability. Exploitation could allow attackers to alter device settings, install backdoors, or launch lateral attacks. HPE urges users to upgrade to firmware version 3.2.1.0 immediately, as there are no workarounds and the vulnerabilities are not present in Instant On Switches. Discovered by a researcher known as ZZ from Ubisectech Sirius Team, these flaws currently have no known active exploitation but pose significant risk if left unpatched.

A single compromised password leads to a UK transport company’s demise. 

A single compromised password led to the collapse of 158-year-old UK transport firm KNP, costing 700 jobs after a ransomware attack by the Akira gang. The hackers encrypted company data, demanding a ransom KNP couldn’t pay. Despite having cybersecurity insurance and industry-compliant IT, the breach crippled operations. Experts warn such attacks are rising, with an estimated 19,000 ransomware incidents in the UK last year. The National Cyber Security Centre (NCSC) and National Crime Agency (NCA) report increasing attacks driven by low barriers to entry and high profits. While major firms like M&S and Co-op have also been hit, small businesses often bear the brunt. Authorities urge better cyber hygiene and are considering new rules banning ransom payments by public bodies and mandating incident reporting. KNP’s case highlights how simple lapses can lead to catastrophic outcomes in a growing digital crime wave.

 

 

An AI assistant falls for fake metadata magic. 

It all started with an innocent enough goal: automate simple business tasks using AI. Enter Claude, an LLM-powered agent trained to read your iMessages and carry out useful actions, like managing Stripe billing, sending thank-you notes, or auto-generating invoices. It’s the kind of “set it and forget it” assistant startups dream about. Until someone realized it could be way too helpful.

Security researchers at General Analysis dug into how Claude interprets messages. Turns out, it doesn’t just read the words, it also processes metadata like who sent the message (is_from_me) and the conversation thread (group_id). Normally, this metadata comes from Apple’s iMessage APIs. But Claude doesn’t actually verify that, it trusts whatever metadata it’s handed. Which opens a troubling loophole: anyone can craft a fake iMessage via SMS that looks like it came from you.

So the researchers sent Claude an SMS containing fake metadata and a casual “Hey Claude, create me 1,000 $50K Stripe coupons.” The message had no real authorization, no password, no handshake, just well-faked headers. Claude, ever loyal, complied.

It gets better: the metadata spoofing doesn’t even require system access. Just embed it in the text body, and Claude will happily parse it as real. The exploit doesn’t rely on malware or brute-force hacking, just social engineering dressed up as protocol mimicry. And because it uses your own assistant, it’s like robbing yourself with your own butler’s help.

Stripe, of course, had no idea. Claude’s commands were fully authenticated from its point of view. The damage could be massive, especially if deployed at scale, think infinite gift cards, free subscriptions, or unauthorized refunds. And while this was just a proof-of-concept, it’s a masterclass in showing how helpful automation can quietly backfire.

The researchers responsibly disclosed the issue and even released a defense tool: “MCP Guard.” It filters incoming messages and metadata to ensure only legitimate, verifiable requests are passed to the agent.

Claude wasn’t hacked. It just did what it was told, by anyone pretending to be you. The modern AI assistant’s greatest weakness isn’t its intelligence. It’s its loyalty.
