Published

on

The US Cybersecurity and Infrastructure Security Agency (CISA) has delivered an educational report on the top took advantages of weaknesses of the 2020 and 2021 years. The report uncovers that most designated focuses for aggressors are the weaknesses that were delivered in the year after 2019 and related to remote work exploited without vpn patches access, VPN (Virtual Private Network) as well as cloud-based technologies.

Remote work exploited without vpn patches has become a common practice hacker are taking advantage of remote work-related vulnerabilities that were not patched and cyber-defenders have had to catch up with the regular software patching. If exploited, computers could be controlled by hackers employing remote code execution (RCE) as well as arbitrarily executed code as well as path traversal, and other methods.

Risks increase as remote Worker Needs Increase

The 12 vulnerabilities identified that are listed by CISA (Table 1) indicate that hackers often attack recently discovered remote workplace-related vulnerabilities. The top three vulnerabilities on the list are linked to Remote work exploited without VPN patches working, VPN, and cloud-based environments. Nine of the flaws were discovered in or after the year 2019.

Remote vulnerabilities related to work could be a draw for hackers in the year 2020. Cloud collaboration tools easily caused an error on security-related configurations.

As we have discussed in our annual security roundup in 2020 Virtual VPNs (VPNs) have become essential for businesses that want to expand and secure their network’s internal connections from threats external. A lot of organizations and users are using VPNs in their workplaces and private homes. Usage spiked in early 2020, and an early 2021 study indicated that 31 percent of Internet users have used VPN. Although the VPN is an effective security tool it also acts as an entry point for cyber-attacks. In reality, unpatched or obsolete VPNs are prone to hosting critical vulnerabilities and hackers can exploit these vulnerabilities to attack the systems of their targets.

Data illustrate the detection figures for some of the most well-known and widely-used VPN vulnerabilities in the year 2020 and into the first part of 2021. We discovered that there was an unexpected increase in the number of detections for CVE-2018-1379 at the beginning of January 2021 and even though the number of detections dropped in the later months, however, they were significantly higher than they were at the time last year. CVE-2018-1379 is a flaw within the Fortinet VPN product that allows users who are not authenticated to download system-related files using specially designed HTTP requests to resources.

CVE-2019-197781 is a great illustration of how attackers exploit the window that is not patched to exploit a flaw.

It is believed that the Citrix Netscaler Application Delivery Controller (ADC) flaw was among the most frequently exploited vulnerability in the year 2020. ADC is a load-balancing application that is used for applications, web, and database servers utilized across the United States. Devices that are not patched are susceptible to RCE as well as the entire system failure due to inadequate access controls, thereby allowing directory traversal.

CVE-2019-197781 was released in the last quarter of the year and was shortly thereafter attacked by numerous exploits. The exploits were distributed across a variety of countries including those in the United States, Colombia, Argentina as well as Switzerland. The attacks abated during the first half of 2021. There were under 7,000 attacks being detected using Trend Micro Intrusion Prevention System (IPS) solutions.

Old Vulnerabilities, Longtime Favorites

While new faces are emerging, however, some of the old vulnerabilities are still popular among attackers. CVE-2017-1882, CVE-2018-7600, and the CVE-2019- are among the list of the top 10 vulnerabilities in the “Most Exploited Vulnerabilities 2016-2019” Also, they made the top 10 for 2020.

For instance, CVE-2017-11882 an issue related to Microsoft’s Object Linking and Embedding (OLE) technology, has been an old favorite that has been associated with suspected cyber-attacks by state-sponsored hackers who originate in China, Iran, North Korea, and Russia. It’s not just because Microsoft Office is used in all parts of the world however, the majority of people don’t regularly update Office frequently with the latest patches. This leads to RCE on systems that are vulnerable. Although in the first quarter of 2021, even though the number of exploits is considerably lower than it was at its highest in 2019, it’s still a vulnerability with a high patch priority.

The Advantages of Using Communication As a Service in Cloud Computing

Cloud computing uses the Internet to access data, applications, and services that would otherwise require an in-house server. It involves a global server network that provides various online services.

Communication as a service in the cloud offers many advantages over on-site solutions. These include scalability, mobility, and flexibility.

Scalability

One of the most important benefits of using communication as a service in cloud computing is its scalability. This feature enables businesses to increase their storage capacity, processing power, and networking as necessary. This also helps to reduce capital expenditure (CapEx) costs.

Scalability is the ability of a system to adapt to changes in its demands and to increase or decrease the number of users, applications, and resources it supports. It is essential for any business that wants to keep growing and expanding.

A company with scalability can continue serving its clients without losing efficiency or performance. Moreover, it can improve its performance and adapt to new processes for efficient operations.

Whether it’s a computer system or business change, scalability is essential to maintain competitiveness and efficiency. It’s also vital to maintaining quality and reputation in the industry.

As the need for scalability increases, organizations need to be more careful about their technology choices. This includes choosing a scalable cloud solution for the company’s needs.

In addition, scalability testing is vital to ensure the system can handle increased workloads and user requests. This can include measuring response time, number of requests, and CPU load.

The scalability of a communication system depends on its programming and design. The software that powers it should be able to scale with the demands of the users, and this should not impact its quality or functionality.

Mobility

CaaS (communications as a service) is a cloud-based solution that provides unified communication capabilities such as chat, voice and video conferencing, telephony, SMS, and email services. It also offers advanced integration, independence, and scalability to meet the needs of modern-day digital-first organizations.

As a cloud-based solution, companies can move away from their legacy landline-based communication systems and replace them with online solutions that work on any device. It also helps businesses to reduce the cost of providing business communications.

It allows employees to access their data anywhere, using any internet-capable device. This means they can easily connect with their co-workers and customers, allowing them to share documents and files and collaborate more efficiently.

In addition, it can be used to build mobile applications that are easy to manage and use from anywhere. It can also support business continuity and disaster recovery (BCDR) by storing important information in the cloud to be accessed even if a company suffers damage or disruption.

Flexibility

Cloud computing enables businesses to scale up and down as needed, allowing employees to access their files and systems from anywhere with an Internet connection. This flexibility makes it easier for companies to adapt to changes in the marketplace and enables them to meet their customers’ needs quickly.

The cloud provides various resources, from data storage to email to business applications. It also offers companies substantial cost savings by eliminating the need for costly hardware and software infrastructure.

In cloud computing, your work and data are stored in substantial computer clusters that can be reached from any device connected to the Internet. These resources can be easily accessed and shared with others.

Cloud computing is accessible, as it only requires a web browser to access a service. It’s also reliable, allowing you to move your data and workloads without disrupting your operations.

Here, your business receives ready-made applications as services from a third party over the Internet. This model can be used for various applications, including document processing, accounting, and project management.

Another type of cloud service is CaaS (Communications as a Service). This model combines phone service, video conferencing, group messaging, SMS, and fax into a single interface that can be accessed on any device or platform.

Cost

Using communication as a service in cloud computing can help businesses of all sizes save money on capital expenditure or “CapEx” costs. This is because cloud-based services require users to pay only for the features they use, only some of the infrastructure necessary for a full-blown premise-based communications solution.

Moreover, businesses don’t have to shell out for costly hardware or software that can be difficult to manage and maintain. The service provider handles the hardware and software and ongoing maintenance, upgrades, and improvements.

Another cost advantage is that cloud-based systems offer unlimited scalability, which helps firms adjust to dynamic market demands. This enables companies to add or remove users and functionality based on demand quickly.

Finally, cloud-based unified communications also provide enhanced reliability to streamline operations. Most providers boast in-built geo-redundancy features, which ensure continuous availability and minimal downtime.

Regardless of your business size, you can use a communications platform like CaaS to streamline your workforce and improve customer engagement. This technology merges telephony, video conferencing, group/team messaging, SMS, fax, and other communication tools into one interface that can be used on any device or platform.

Top 5 Causes of Data Breaches and How to Prevent Them

Top 5 Causes of Data Breaches and How to Prevent Them

In an age where data breaches are becoming increasingly common, individuals and businesses need to understand why these events occur.

Human Error

Human error is one of the leading cause of data breaches. Using weak passwords, falling for phishing scams, or unintentionally giving sensitive information to the incorrect person can contribute to this.

However, these errors can be prevented with the right security training and systems. According to a survey by Egress, 84% of IT leaders said human error was the top cause of serious data breaches.

The cost of a breach can be very high and can have serious consequences for an organization. This includes the regulatory fines that can be levied, loss of brand reputation, and a significant reduction in profits.

Often, these mistakes seem innocuous at the moment but are costly in the long run. For example, when an employee casually left a prototype of the latest iPhone in a public location, which was stolen hours later.

The result was that the device’s specifications were made publicly available, causing a major financial loss to the company. This is why it’s so important to prevent human error in cybersecurity.

Password Theft

Password theft is one of the most common causes of data breaches. It’s caused by people using weak passwords across multiple accounts, making it easy for hackers to gain access.

Numerous methods, including phishing scams and other social engineering attempts, can result in this. Credential stuffing, the practice of users using the same login information across many websites, may also be to blame.

The same username and password combination, for instance, might be used by a hacker to access Facebook and other internet services like email or bank accounts.

The damage from a compromised password can be severe. It can lead to identity theft and fraud. It can also put a company at risk of data breach by allowing hackers to steal sensitive information.

People can take several steps to reduce the risk of password theft and data breaches. They should avoid disclosing too much private information, keep the number of accounts they have to a minimum, and use secure passwords specific to each website.

Insider Misuse

One of the most common causes of data breaches is insider misuse. This occurs when an employee, contractor, or vendor accesses sensitive information without authorization.

It is a type of breach that is not as widely recognized as other types of breaches, but it’s still an issue that should terrify any business owner. An insider could steal credit card data, classified government documents, or other sensitive information.

These attacks can be perpetrated by employees, vendors, or contractors and can affect any organization with confidential data. The motivation behind these attacks can range from personal financial gain to revenge.

An insider’s actions can also result in the destruction of property or systems or the theft of customer or user information. These incidents can negatively impact a company’s reputation, leading to legal fees and client distrust.

Implementing a strict user termination policy is the most effective way to prevent these threats. This will ensure that employees who are leaving your company don’t leave with sensitive data they may be trying to use fraudulently or maliciously.

Physical Theft

Physical theft is a common cause of data breaches, especially when companies rely heavily on hard drives and other hardware. These devices can be lost, stolen, or left unattended at public locations, and they are particularly vulnerable to a hacking attack.

In many cases, these devices can contain sensitive information that should be encrypted and backed up in case they get lost or corrupted. However, not all companies take these measures.

Theft is a general term that covers a wide range of deceitful takings, including larceny and swindling. It also includes embezzlement and pretenses.

While larceny refers to the taking of physical property such as cars, computers, or clothing, some jurisdictions have consolidated all these offenses under the general category of theft.

This is important to understand because some of the most expensive and damaging data breaches happen when insiders commit fraud, sabotage, or intellectual property theft.

Criminal Hacking

Data breaches occur when unauthorized individuals or groups access sensitive information. It could be personal, corporate, or financial data.

Most of these data leaks are caused by cybercriminals who use their skills and resources to hack into a system or network without the owner’s consent. They can access accounts’ login credentials, credit card numbers, contact information, email and home addresses, and more.

Typically, these data thieves want to sell their stolen information on the dark web for a profit. They can also use this information for identity theft.

Some hackers are politically or socially motivated and will release information for a cause. These are called “hacktivists” and have been responsible for some notable breaches, such as WikiLeaks and Anonymous.
