microsoft released outofband update patch

On March 10, 2020, Microsoft released an out-of-band update patch that caught the attention of the tech world. This unexpected release was due to the discovery of a critical vulnerability in the Windows operating system, which posed a significant threat to millions of users worldwide. The urgency of this update was evident as Microsoft typically releases patches on the second Tuesday of every month, known as “Patch Tuesday.” However, this out-of-band update was necessary to prevent potential cyberattacks and protect users’ data. In this article, we will delve deeper into the details of this update, its significance, and the implications for users.

To understand the significance of this out-of-band update, we must first understand what it means. Simply put, an out-of-band update is a software update released outside of the regular update schedule. It is usually issued when a critical vulnerability is discovered that requires immediate attention. In the case of Microsoft, they follow a monthly update schedule, and any update released outside of that schedule is considered out-of-band. These updates are not to be taken lightly as they typically address severe security issues that can compromise the integrity of the system.

The out-of-band update released by Microsoft on March 10 was for a critical vulnerability in the Windows operating system, specifically in the Microsoft Server Message Block 3.1.1 (SMBv3) protocol. This protocol is responsible for facilitating file and printer sharing between devices on a network. The vulnerability, named “SMBGhost,” was discovered by the security firm, Check Point Research, and was given a severity rating of 10 out of 10, which is the highest possible rating. This meant that if left unpatched, the vulnerability could be exploited to execute remote code on a target system, giving hackers complete control over the device.

The discovery of this vulnerability sent shockwaves across the tech industry, as SMBv3 is a widely used protocol in both home and enterprise networks. It is a core component of the Windows operating system, and its exploitation could have catastrophic consequences. The potential damage that could be caused by this vulnerability was so severe that Microsoft took the unprecedented step of releasing an out-of-band update.

The out-of-band update, codenamed “CVE-2020-0796,” was made available to all supported versions of Windows, including Windows 10, Windows Server 2019, and Windows Server 2016. It was a critical update that needed to be installed immediately to protect against potential cyberattacks. The update was available through the standard Windows Update channel, and users were strongly advised to install it as soon as possible.

One of the main reasons why this vulnerability was considered so severe was its ease of exploitation. The SMBGhost vulnerability could be exploited remotely, without any user interaction, making it an attractive target for hackers. All they needed to do was send a specially crafted packet to a vulnerable system, and it would execute the code without the user’s knowledge. This made the vulnerability a ticking time bomb, and the out-of-band update was the only way to defuse it.

The potential damage that could be caused by this vulnerability was not lost on Microsoft, and they were quick to address it. The company released a statement, urging users to install the update immediately, stating that “it is important that affected systems are patched as quickly as possible to prevent such a scenario from happening.” They also acknowledged the severity of the vulnerability, stating that “the update addresses a remote code execution vulnerability that exists in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially crafted multi-master font – Adobe Type 1 PostScript format.”

The urgency of this update was also evident in the fact that it was made available to all supported versions of Windows, including those that are no longer receiving regular updates, such as Windows 7 and Windows Server 2008. This was a clear indication of how seriously Microsoft took this vulnerability and the potential consequences of not patching it.

The release of this out-of-band update highlights the importance of regular software updates. These updates are not just about adding new features or improving performance; they also play a crucial role in keeping our devices safe and secure. Microsoft typically releases updates on the second Tuesday of every month, and these updates include fixes for known vulnerabilities. However, this does not mean that users should wait for the monthly updates to install them. Hackers are continuously looking for vulnerabilities to exploit, and it only takes one successful attack to cause significant damage. This is why it is essential to install updates as soon as they become available, as they often contain critical security fixes.

The release of this out-of-band update also raises questions about the effectiveness of Microsoft’s security protocols. The fact that such a severe vulnerability went undetected for so long highlights the need for regular security audits and bug bounties. Microsoft has a dedicated team of security experts who continuously monitor their software for potential vulnerabilities. However, it is impossible to catch every single one, and this incident serves as a reminder that there is always room for improvement.

In conclusion, the out-of-band update released by Microsoft on March 10, 2020, was a wake-up call for users worldwide. It highlighted the critical role that software updates play in keeping our devices safe and secure. The discovery of the SMBGhost vulnerability was a stark reminder that cyber threats are constantly evolving, and we must stay vigilant to stay one step ahead of them. As users, we must take the necessary steps to protect ourselves, and this includes installing updates as soon as they become available. We must also hold companies accountable for the security of their products, and incidents like these should serve as a reminder that there is always room for improvement.

reasons phones should not be allowed in school

The use of technology in schools has become a controversial topic in recent years. With the rise of smartphones, it has become increasingly common for students to bring their devices to school. While some argue that phones can be a useful learning tool, others believe that they should not be allowed in school. In this article, we will explore the reasons why phones should not be allowed in school.

1. Distraction
One of the main reasons why phones should not be allowed in school is the distraction they create. Students are easily tempted to check their messages, browse social media, or play games during class, which can disrupt their learning and the learning of others. A study by the University of Nebraska-Lincoln found that students who use their phones in class have lower academic performance compared to those who don’t. Phones not only distract the individual student but can also cause disruptions for the entire class.

2. Cyberbullying
Bullying has always been a problem in schools, but with the advent of smartphones, it has taken on a new form – cyberbullying. Cyberbullying is the use of technology to harass, intimidate, or embarrass someone, and it has become a major concern in schools. According to a survey by the Cyberbullying Research Center, over 34% of students have experienced cyberbullying, and 17% have been cyberbullied on school grounds. Allowing phones in school increases the risk of cyberbullying, as students have constant access to social media and messaging apps.

3. Cheating

Another concern with phones in schools is the potential for cheating. With the ability to access the internet and store information on their phones, students can easily cheat on tests or assignments. This not only undermines the integrity of the education system but also puts students who do not have access to phones at a disadvantage. It also creates a culture of shortcuts and dishonesty, which can carry over into other aspects of their lives.

4. Health and Safety
Phones emit radiofrequency (RF) radiation, which has been linked to health concerns such as brain tumors, infertility, and behavioral problems. Exposure to RF radiation is especially concerning for children and teenagers, as their brains are still developing. Allowing phones in school means students are exposed to this radiation for extended periods, which could have long-term effects on their health. Furthermore, phones can also pose a safety risk, as students may be too engrossed in their devices to pay attention to their surroundings, making them vulnerable to accidents.

5. Disparity and Inequality
Not all students have access to smartphones, and allowing phones in school can create a divide between students who have phones and those who don’t. This can lead to feelings of inadequacy and exclusion for students who cannot afford a phone. It also puts pressure on parents to provide their children with the latest and most expensive devices, which may not be feasible for some families. Schools should be a place where students are equal, and allowing phones can create a disparity between students based on their economic status.

6. Loss of Social Skills
With the constant use of phones, students are losing the ability to communicate and interact face-to-face. They rely on their devices to communicate, even when they are in the same room. This can lead to a lack of social skills, which are crucial for success in the real world. In addition, students may also miss out on important social interactions and opportunities to develop friendships if they are constantly glued to their phones.

7. Negative Impact on Mental Health
The use of phones has been linked to negative effects on mental health, especially in young people. Studies have shown that excessive phone use can lead to anxiety, depression, and sleep disturbances. Allowing phones in school provides students with unlimited access to their devices, which can contribute to these mental health issues. It also makes it easier for students to compare themselves to others on social media, leading to feelings of inadequacy and low self-esteem.

8. Disrupts Attention and Memory
The constant use of phones has been found to disrupt attention and memory, which are crucial for learning. A study by the University of California, San Francisco found that students who are constantly connected to their phones have a harder time focusing and retaining information. This can have a significant impact on their academic performance and overall success in school.

9. Inappropriate Content
With the internet at their fingertips, students can easily access inappropriate content such as violence, pornography, and hate speech on their phones. This not only exposes them to harmful and disturbing material but can also desensitize them to these issues. It also puts the responsibility on teachers and school administrators to monitor and filter the content students are accessing on their devices, which can be a daunting task.

10. Creates a Sense of Entitlement
Allowing phones in school can create a sense of entitlement in students. They may feel that they have the right to use their phones whenever they want, even during class. This can lead to a lack of respect for authority and rules. It also reinforces the idea that students should always be entertained and have access to their devices, rather than focusing on their education and learning.

In conclusion, there are many valid reasons why phones should not be allowed in school. From distractions and cyberbullying to health concerns and negative impacts on mental health, the use of phones in schools can have a detrimental effect on students’ learning and well-being. While technology has its benefits, it is important to set boundaries and limit its use in the educational setting to ensure a safe and productive learning environment for all students.
