Gentoo Linux Security Advisory 202405-02

Remember Minesweeper? It's not just a game - it's a hidden training ground for work skills! Sharpen your decision-making, focus, and strategic thinking with every click.
This is a post from HackRead.com Read the original post: A Mind at Play: Rediscovering Minesweeper in the Professional Arena

Do you remember the first time you stumbled upon Minesweeper online? It could be during a lazy afternoon at a school computer lab or a quick break at your first job. Something about that grid of grey squares beckons like a puzzle waiting to be solved—a momentary escape that, surprisingly, could be one of your best tools for professional growth today.

****The Puzzle of Decision-Making****

Imagine you’re back in that chair, the mouse under your fingertips. Each click in Minesweeper isn’t just a guess; it’s a decision with risks and rewards that are not unlike the choices you face in your career.

Like navigating through a particularly tricky business dilemma, each square you uncover on the Minesweeper grid teaches you more about the landscape, helping you make the next decision more informed. It’s a dance of logic and anticipation—skills that, when refined, translate into a sharp acumen for analyzing complex professional scenarios.

Remember that feeling when you correctly predict a mine’s location? That’s your analytical skills growing more strong, one click at a time.

****A Masterclass in Focus****

Now, think about the intense concentration Minesweeper demands. Each square could mean triumph or game over, akin to the high stakes of missing a critical detail in a client report or a coding error in a software launch.

This game hones your ability to focus and pay attention to the minutiae—skills that elevate the quality of your work and your productivity. The game’s grid challenges you to spot inconsistencies and patterns, just as in a complex dataset or a crucial project blueprint.

****Strategizing Several Steps Ahead****

Strategic foresight in Minesweeper involves planning several moves, assessing potential outcomes, and managing risks—essential for effective project management and long-term planning in the professional realm. Playing Minesweeper cultivates a mindset that values strategic preparation and adaptability, preparing you to steer projects and negotiations toward success.

****Unwind and Adapt****

Beyond sharpening your technical skills, Minesweeper is a refuge from the daily grind. The familiar grid offers a structured yet soothing distraction that can help clear your mind, akin to meditation. It’s not just about escaping stress but about adapting to it and managing it—key for sustaining performance during crunch times at work.

Moreover, the mental flexibility needed to toggle between strategies in the game mirrors the rapid switching between tasks that’s common in today’s workplace, enhancing your cognitive agility.

****Ready at Your Fingertips****

One of the most significant benefits of Minesweeper is its accessibility. Whether you have a ten-minute break or just a few moments between meetings, it can engage your brain without a substantial time investment. These short bursts of cognitive exercise can strengthen mental agility, fostering a strong cognitive reserve that enhances career longevity and success.

****Conclusion: More Than Just a Game****

As you integrate Minesweeper into your daily routine, you’ll find it’s more than nostalgic play; it’s a deliberate practice in cognitive enhancement. Each game is a step towards becoming a sharper, more attentive, and strategic professional. So, next time you need a break, consider spending it with Minesweeper—not just for fun but also for your professional development.

Rediscovering Minesweeper in this light might change how you view every click—as clearing mines and planting seeds for a more robust professional future.

Is your coding class engaging and effective? Learn what makes the best online coding classes for kids fun, effective, and future-proof!
This is a post from HackRead.com Read the original post: A Checklist for What Every Online Coding Class for Kids Needs

Parents everywhere are eager to sign up their kids for online coding classes to ensure they’re ready for life and the workforce of the future. Nobody can say with 100% accuracy what the future will hold, but surely, in our digital society, it will be high-tech!

How can parents know which online coding classes are better than others? Here’s a checklist that outlines what the best coding classes offer.

****1\. Fun and Video Games Above All****

Parents want their kids to learn to code online, but having fun after school is even more important. The best coding programs embed games into their classes by teaching kids how to design and program their own video games, ones they can play afterwards with friends and family.

Parents and teachers won’t have to push kids very hard to learn when the goal is something they’re so hungry to achieve. Gamification dynamics make learning as addictive and engaging as playing video games.

****2\. Small Classes****

Some coding programs claim to teach STEM skills and everything kids will need to know in the future, but they’re overly packed with students, making for a distractive environment where learning is difficult. Students shouldn’t have to deal with busy teachers who are more concerned with classroom management than teaching.

The best coding courses limit sessions to four students per class, so every child gets their teacher’s full attention.

****3\. Leading Coding Languages****

Avoid the coding classes that rely too heavily on programs like Scratch, which is more of a drag-and-drop program designed to give kids a sense of what coding is like rather than a proper coding language employers look for in prospective employees. Nobody uses Scratch in the field to make video games, apps, or websites.

Instead, look for a program that teaches kids the popular, in-demand coding languages, such as:

*   C#
*   C++
*   Java
*   Python
*   JavaScript

The classes should be engaging for young students who are brand new to coding but never overwhelming. As students develop and hone their skills within each language, they progress to the next until they develop confidence and expertise in that language, too.

****4\. Expert Teachers****

Finally, the leading coding courses hire computer science and computer engineering students who also grew up playing video games to pass on their knowledge to the next generation. Such an approach has multiple benefits.

Kids should learn how to code games from teachers who also played computer games growing up and have the expertise and domain knowledge. Practically speaking, high school students have the perfect resources to speak to about the coding jobs available and where else programming can take them after school when their teachers are also navigating the same situation.

Every computer-related program for kids promises to give a strong foundation in STEM skills, but they’re not all the same in quality. Before signing up your child for an after-school coding course, you should know how to recognize a red flag or the signs of a great coding program when you see them.

A new botnet called Goldoon targets D-Link routers and NAS devices putting them at risk of DDoS attacks and more. Learn how weak credentials leave you vulnerable and how to secure your network. pen_spark
This is a post from HackRead.com Read the original post: New Goldoon Botnet Targeting D-Link Devices by Exploiting 9-Year-Old Flaw

Cybersecurity researchers at Fortinet’s FortiGuard Labs have uncovered a new botnet threat dubbed “Goldoon” specifically targeting D-Link routers and network-attached storage (NAS) devices. This malware infects devices by exploiting the CVE-2015-2051 (CVSS score: 10.0) vulnerability, potentially putting user data and network security at risk.

It’s noteworthy to mention that CVE-2015-2051, a security vulnerability identified in February 2015, is nearly a decade old. This vulnerability primarily affects end-of-life devices.

In September 2022, Palo Alto Networks’ Unit 42 discovered that the same vulnerability was being exploited by the infamous Mirai botnet’s variant, known as MooBot, targeting D-Link devices. D-Link addressed the issue in 2015, and further details regarding their response can be found here.

According to the Fortinet report, Goldoon leverages brute-force attacks to gain access to D-Link devices. Brute-force attacks involve systematically trying different username and password combinations until gaining unauthorized access. The report suggests these attacks exploit weak default credentials or outdated firmware on targeted devices.

Once established, Goldoon transforms the infected device into a bot, adding it to a network of compromised machines under the control of the botnet operator. This network of bots can then be used for various malicious activities, including:

*   **Launching Distributed Denial-of-Service (DDoS) attacks:** Bombarding websites or online services with overwhelming traffic, causing them to crash or become unavailable to legitimate users.
*   **Data theft:** Stealing sensitive information like login credentials, financial details, or personal data stored on the infected device.
*   **Spreading malware:** Using the compromised device to propagate malware across a network further, potentially infecting other devices.

The report highlights the critical role of patching and updating firmware on D-Link devices. Outdated firmware often contains vulnerabilities that attackers can exploit. Fortinet recommends D-Link users to:

*   **Enable automatic firmware updates:** Most devices can download and install security updates automatically.
*   **Change default credentials:** Replace the factory-set username and password with a strong, unique combination.
*   **Implement strong network security practices:** Enable firewalls, use complex passwords, and be cautious when clicking on links or opening attachments from unknown senders.

> _“While CVE-2015-2051 is not a new vulnerability and presents a low attack complexity, it has a critical security impact that can lead to remote code execution. Once attackers successfully exploit this vulnerability, they can incorporate compromised devices into their botnet to launch further attacks We strongly recommend applying patches and updates whenever possible because of the ongoing development and introduction of new botnets.”_

Fortinet’s discovery of Goldoon serves as a reminder of the evolving cyber threat landscape. By prioritizing proper device security measures, D-Link users can minimize the risk of falling victim to this or similar botnet attacks.
