Microsoft Rushes To Plug SharePoint Flaws After Wave Of Cyber Intrusions
On July 19, the Microsoft Security Response Center flagged a spoofing bug (CVE?2025?49706) and a remote code execution hole (CVE?2025?49704) in on?premises SharePoint.
Warning! GuruFocus has detected 7 Warning Sign with MSFT.
Advanced groups known as Linen Typhoon and Violet Typhoon have been chaining these vulnerabilities to slip into servers, and a less familiar actor called Storm?2603 is now using them too. Their favorite targets include government agencies, think tanks and universities across the U.S., Europe and East Asia.
If your IT team hasn't applied the new SharePoint patches, any exposed server is at risk of having data from defense plans to donor lists stolen overnight.
Microsoft pointed out that SharePoint Online in Microsoft 365 isn't affected, making the cloud version a safer bet when it comes to rapid security updates.
Rolling out fixes is one thing; getting them installed in complex, custom environments is another. Until everyone catches up, expect more breach headlines. This incident is a stark reminder of why many organizations are accelerating moves from traditional on?premises software to cloud?hosted alternatives.

UPDATE - Labrynth Launches the Red Tape Index to Help America Build Smarter, Faster
New national benchmark ranks Tennessee, Florida and Texas as the top 3 U.S. states by permitting efficiency—advancing economic growth and revealing costly delays in infrastructure development. WASHINGTON, Aug. 08, 2025 (GLOBE NEWSWIRE) -- Labrynth, a regulatory intelligence company dedicated to streamlining permitting approvals across government and industry, today announced the launch of the Red Tape Index. This new index provides the first comprehensive, data-driven benchmark designed to track and compare how efficiently U.S. states process building permits, zoning changes, and related approvals. The Red Tape Index is launching initially with state-level data aggregated from a vast array of public sources, including building departments, zoning boards, and state environmental agencies. According to the first set of rankings, 6 of the top 10 cities in the US hail from the top 3 states: issuing an average of 195 permits per 100,000 residents. The index website identifies the following states as the top 10 using a weighted scoring system: 1. Tennessee 20.1 6. North Carolina 18.7 2. Florida 19.9 7. Georgia 18.5 3. Texas 19.8 8. Virginia 18.1 4. Indiana 19.6 9. Michigan 15.5 5. Arizona 18.8 10. New Hampshire 14.8 *For more information on the data in the above table, including how this list was compiled/created visit In the next 30 days, detailed city and county level insights will be published, this phased approach prioritizes transparency and collaboration. Local governments and stakeholders are invited to engage by submitting or verifying data to ensure accuracy and relevance. To view the full list and explore detailed metrics visit Measuring What Matters Now 'You can't fix what you don't measure,' said Stuart Lacey, CEO of Labrynth. 'The Red Tape Index brings long-overdue transparency to one of the most frustrating and costly challenges in American infrastructure. By spotlighting inefficiencies and highlighting success stories, we're giving public officials and private developers the tools they need to move faster, smarter, and with greater confidence.' Permitting delays remains a significant barrier to building new infrastructure, costing businesses time and money. The Index aggregates publicly available data and integrates direct input from local governments and developers, creating a living platform that will be updated quarterly. This evolving resource aims to provide actionable insights that help public officials identify bottlenecks and enable investors and developers to compare permitting efficiency across regions. Infrastructure development—from data centers and energy projects to housing—relies on timely regulatory approvals. Delays that stretch projects from months into years risk economic growth and competitiveness. Labrynth's Red Tape Index offers a new level of clarity into these critical processes, supporting smarter decision-making for communities and investors alike. A Roadmap, Not Just a Ranking Beyond rankings, the Red Tape Index is part of Labrynth's broader commitment to enabling faster, more transparent project approvals through ongoing initiatives including: The Red Tape 100: A quarterly leaderboard showcasing the top 100 most efficient permitting cities nationwide. The Red Tape Report: Monthly feature highlighting successful reforms and operational innovations built on the successful implementation of new systems and tools driving efficiency.. Monthly Insights: Summary and analysis of trends, regulatory changes, and policy developments nationwide. Get Involved: Help Build a Clearer Regulatory Future Labrynth invites state, county, and city governments to participate actively in refining the Red Tape Index. By submitting or verifying your latest permitting data, they can ensure their jurisdiction's profile accurately reflects their operational reality and improvements. Engagement is simple and vital: Visit to register for the submission portal. Provide key permitting and licensing data or confirm existing information.

S&P 500 has a concentration problem: Why ETFs can't keep up
A handful of giant tech names continue to dominate the S&P 500 (^GSPC), raising challenges for exchange-traded funds (ETFs) trying to mirror the index. Yahoo Finance Markets and Data Editor Jared Blikre breaks down how new funds are working around strict concentration rules. Twice a week, Stocks In Translation cuts through the market mayhem, noisy numbers and hyperbole to give you the information you need to make the right trade for your portfolio. You can find more episodes here, or watch on your favorite streaming service. To watch more expert insights and analysis on the latest market action, check out more Market Catalysts. The S&P 500 has a concentration problem. The most important stock or index in the world is more top heavy than it has been in the last 45 years. The 10 biggest stocks, they make up nearly 40% of the index. What's behind this mess? The rules for registered investment companies or Ricks were created way back in the 1930s and 1940s for mutual funds to make sure they didn't get too concentrated in just a few stocks. But modern ETFs that only go back to the beginning of this century, they have to comply with them too. In particular, these so-called Rick rules, they say that no single stock can make up over a quarter or 25% of a fund. And the sum of all the stocks together making up at least 5%, they cannot exceed half of the fund or 50%. So it's great for diversification, but in a mega cap world, it forces ETFs that are supposed to be passive to dial down the biggest names. Now look at this table of four S&P 500 sectors and their top three stocks. For instance, in communication services, we have Alphabet or Google with 38%, Meta with 31%, Netflix with 10%. Add them up and you get 79%. That is way too far too far over that 50% that's required by the rule. And a similar thing happens with the tech sector with consumer discretionary. And this one surprised me. Even the energy sector, Exxon Mobile, Chevron and Conoco Phillips, they add up to 55%, just a little bit too high. But the bottom line is an ETF cannot just copy and paste that concentration and still pass the Rick test. They have to cut their biggest weights. Now here is the real world impact. In this chart right here, the performance of the S&P 500 tech sector in green, this is since the start of this bull market in October of 2022. That white line below it, that is a performance of the technology select spider fund, which we know by the ticker XLK. All you need to notice is that big gap between the two lines at the right side of the chart. XLK is up 126%, but the actual tech sector of the S&P 500, that's up 158%. And that is a difference of 32 percentage point. That's a big gap. Here's the same story in a table that shows the gap in performance for all four of the sectors we've been discussing over this nearly three-year-old bull market. Tech has the biggest difference. We just took care of that. But communication services with alphabet and meta, that has a difference of 16 percentage points. Then you can see there's only a small difference of three percentage points for consumer discretionary. That's where you find Amazon and Tesla. And there's virtually no difference for the small returns in the energy sector, which is more or less traded sideways through through this bull market. So here comes the fix. There are newer ETFs designed to get closer to the index concentration while remaining compliant with all the rules. This table here, it focuses exclusively on the tech sector and its three biggest weights. Those would be Nvidia, Microsoft, and Apple. We have the weights of each within the S&P 500, the weights within the new global X pure cap tech ETF with the ticker GXPT. And finally, at the bottom, we show the weights in XLK, which we've discussed, has been around most of this century. Note that the new GXPT ETF gets much closer to the weights in the S&P 500 for those three stocks. Now, finally, this table here shows the total weight of those three stocks, Nvidia, Microsoft, and Apple in each of the same three instruments from the last table. S&P 500 tech sector, GXPT, and XLK. Now the new GXPT at 60%, it gets pretty close to the S&P 500 tech sector at 62%, while XLK is stuck down at 42%. Now, there is a trade-off to getting around all these concentration rules, and it comes down to fees. GXPT charges a management fee of a quarter of 1% per year, while XLK, it's only 0.03%. That's 1/8 of the new tech ETF. So you're paying more to get closer to that concentrated index profile. I should also add that the select spider funds like XLK and XLY, they aren't doing anything wrong. They're just following the rules that they've been in place for decades. So the bottom line is, in today's market, it's built around a handful of colossal winners and concentration, it may ease or it may stick around, but at least now you can choose how closely you want to ride with the giants.
