The Coronavirus & the Cloud – A Winning Combination for Hackers

Originally posted on People and Computers

“The combination of changing work patterns due to the coronavirus, with the increasing migration to cloud environments, creates a new and significant challenge for corporate information security managers,” said Ofer Amitai, one of the founders and CEO of Portnox, explaining how it can be answered at the identification stage.

“One day, a food supplier from abroad called me. One of the company’s employees, who was fired, connected to the organization’s operating systems, changed the temperature of the meat refrigerators and caused damage and loss of goods worth millions of dollars. That’s how they understood that more vital identification is needed on the network and contacted us, “Ofer Amitai, one of the founders and CEO of Portnox, told People and Computers.

“The coming period will be characterized by hybrid work. This format makes remote work an integral part of all workers’ activities, and those who have not yet dealt with a remote work method will do so today or tomorrow. It will enable regular work alongside the protection of the organization and its resources. The combination of changing work patterns due to the coronavirus, with the growing migration to cloud environments, creates a new and significant challenge for corporate information security managers, and is a winning combination for hackers,” continued Amitai.

What is the main challenge for information security managers?

“Above all the challenges facing the information security manager, there is a major challenge, and that is that he must understand who and what threats he is facing,” Amitai noted. “One of the most difficult challenges for the organization is the migration to the cloud – how the systems and data will be kept secure in this new environment on the one hand, and that all systems will work on the other. Israel is slightly behind cloud adoption compared to the US market. It will be like the main headquarters so that one day everything will be connected to the cloud, and the services will be consumed from it, without the need to join the offices to the branch. ”

He added that “when setting up secure access control to the corporate network, make sure that application-level privileges are managed – whether via remote connection (VPN) or user management (VDI), which allows remote, virtual access to the desktop. Connection security must also be ensured via MFA – multi-step authentication of the user. Then the end station must be handled, including personal devices that employees bring from home. The goal is to maintain a consistent level of information security, regardless of the identity of the end device.”

A significant promise – but also risky

Portnox was established in 2007 to help organizations protect their corporate networks through the use of technology that allows them to see all devices connected to the network and to perform preventative and corrective actions that defend it from risk-prone devices. “This is a technology that makes life easier for information security managers in their day-to-day work,” Amitai explained.

“When someone accesses the network – via a remote, local connection or cable – Portnox knows how to make a strong identification of the device and the user. We do not manage the end component, but its risks,” said Amitai. “Our product in the cloud, Portnox CLEAR, enables organizations to protect the enterprise network via the cloud. The solution complements the security layer for VPN and VDI solutions. Through continuous risk monitoring capabilities on end stations and devices, information security principles are maintained and enforced – regardless of physical location. The end station, whether inside or outside the organization, and owned by it, or whether it belongs to the company or the employee, thus, all stations become secure and authenticated devices, which comply with the organizational security policy – all through enforcement, by the policy definition The organization, which changes according to its needs. ”

In conclusion, Amitai stated that “all the trends in the market bring with them a great promise – but also risks. They expose organizations to more hacks into their network, which makes them look for security solutions like ours – smart, easy to manage, and those who make sure the corporate network is secure. We have a wide range of enterprise and SMB clients who come from many sectors, including the medical, banking, and high-tech sectors. In the past year, we have experienced a 30% increase in revenue, and I estimate that the growth trend, which continues this year, will continue in 2022.”

Do you know what VMWare is and how to include it in monitoring?

Find out what VMWare is and how to include it in monitoring

Background

Before we dive into how to monitor virtualized environments with VMWare, let’s clarify a couple of concepts for those who are less into the subject, starting withWhat is VMWare?.

VMWare is a software product development company, mostly related to virtualization, and more recently to containerization, although this is beyond the scope of this article. Today, we are going to focus on monitoring virtualized environments with VMWare.

To do this, the first step would be to know what virtualization is. A quick summary, and a bit imprecise I must say, but that will give you a general idea. We can claim that virtualization is like dividing the components (CPU, Memory, Disk, etc.) of a physical computer or server (which we will refer to from now on as Bare-Metal) into virtual or emulated components. This will allow us to share the same component between different instances which we will call “virtual machines.” That way, using a single set of hardware, you may have different virtual machines running different versions of operating systems, applications, libraries, etc. simultaneously and separate from each other.

The interesting thing about this is that, for the virtual machine (which we will refer to as VM from now on), the resources that have been assigned to it are only from it and are real elements. This opens a world of possibilities, it allows you to have many services and virtual machines running on a single hardware device with the energy, space and cost savings that this implies. In addition, since it is all at software level, it will allow you to manage the machine as one more file inside the computer, being able to copy it, modify it or even package and distribute it.

The advantages of virtualization are more than proven and today almost any service and infrastructure runs mostly on virtual servers. A very clear example is when you go to your favorite cloud provider and click a button to activate an instance of a database or a server, actually what you’re doing is activating a virtual machine that it already had pre-configured and that can work for you in a matter of seconds, thanks to this technology.

Due to these types of advantages, and because of the massive distribution of virtual machines in most ecosystems, it is so important to have a monitoring tool capable of adapting to this type of environment efficiently.

Now that we know what virtualization is, we will see a new concept. We already said that from a physical machine we can emulate and subdivide its components to create instances of smaller virtual machines, and it is true, although there is a small nuance, we require software devoted to this, we call this software hypervisor.

There are different types, manufacturers and features we are not going to delve into today. If you are interested in this topic and want us to do a more detailed article on virtualization leave it in the comments

vSphere

Today we will focus on one of VMWare’s most widespread and well-known products: the vSphere suite which, according to Wikipedia, “is VMware’s core business suite, the cornerstone on which almost all the business products they offer rely on. It consists of the ESXi virtualization software that is installed directly on the servers and the centralized management console vCenter.2020 ”

As we have seen, vSphere is the name of the set of tools that VMWare offers for device virtualization, there is a range of different vSphere environments, from a single ESXi server that works as a hypervisor as well as management.

Stand alone ESX [esxi.jpg]

To much more complex environments where several ESXi work in parallel being managed by a centralized administration software called vCenter.

vSphere Vcenter [vsphere.png]

Virtual environment monitoring

To monitor virtual environments, whether it is from VMWare or not, there are two main ways.

The first is to treat each virtual machine as an independent machine, attacking its operating system with standard protocols or using some monitoring agent.
This approach does not require for the tool have a special or devoted management, since it will deal with each VM as any other machine. Along this approach, we can say that we will interrogate the operating system, therefore, in heterogeneous environments, we must define metric captures for each system.

The second way is more general and allows deploying monitoring very quickly and efficiently. In this case we will integrate the hypervisor, since it has information on all the machines it contains and we can interrogate it directly. For each manufacturer the protocol, the responses and the format with which we will interrogate the hypervisor may vary, but in most cases they have an interface to communicate with it. Along this approach, it is the monitoring tool that must be adapted and have a connector to communicate with the supervisor in a centralized way.

Of course, Pandora FMS has both types of monitoring, being able to combine them if necessary if deep and detailed monitoring is required.

In today’s case, we will see the monitoring integrated in Pandora FMS Enterprise Discovery tool. That will allow us, in a very simple way, to connect well, either with a standalone ESX or with a vcenter, through the vmware SDK.

vSphere Monitoring with PandoraFMS

Starting from the fact that we have a Pandora FMS Enterprise instance, the steps are very simple: by default Pandora FMS has the necessary libraries to connect to a VMWare environment, you only need a user account with reading permissions and connectivity with the ESX or vCenter as the case may be.

Once you fill in the simple form with the data from our VMWare environment:

[discoveryapp]

[form2]

You will see a window to configure some monitoring data, such as the scan interval for new machines, the execution threads that you will devote to this task, if you want to activate network monitoring and (only for vcenter), if you want to capture the environment events.

You will also have a field for extra configurations that will allow you to add advanced configurations related to the task (you can see the possible configurations:
https://pandorafms.com/manual/en/documentation/03_monitoring/05_virtual_environment_monitoring?s[]=vmware#vmware 1 plugin ocnfiguration ).

[form3]

Once finished, you will be able to see that a task has been added to Pandora FMS task list, where you will be able to see its last execution, enable it, disable it or force task execution manually.

[form4]

The default task will give you information about all the ESXs (in the case of vcenter), virtual machines and datastores available in the vmware environment that you configured, returning the following metrics:

Default monitoring for Datacenter:

Ping
Check 443 port

Default monitoring for Datastore:

Capacity
Free Space
Disk Overallocation
Free Space Bytes

Default monitoring for ESXi:

CPU Usage
Memory Usage
Received data
Transmitted data
Disk Read Latency
Disk Write Latency
Host Alive
Disk Rate
Net Usage

Default monitoring for virtual machines:

CPU Usage
Memory Usage
Tools Running Status
Host Alive
Disk Free
Disk Read Latency
Disk Write Latency
Received data
Transmitted data
Net Usage

In addition to the metrics described, you will also have a specific view for monitoring vSphere environments that has compilation information on the general state of the environment and each monitored ESX and even a map of the monitored infrastructure.

[view3]

As you can see, it is very easy to start monitoring a vSphere environment with Pandora FMS, just follow a few steps and you will have your VMWare monitoring integrated quickly and easily.

Android/FakeAdBlocker misuses URL shortener services and iOS calendars, and distributes trojans to Android devices

BRATISLAVA, KOŠICE — July 20, 2021 — ESET Research has analyzed an aggressive advertising-based threat — Android/FakeAdBlocker — which downloads malicious payloads provided by its operator’s command and control server. Android/FakeAdBlocker usually hides its launcher icon after initial launch, delivers unwanted scareware or adult content advertisements, and creates spam events for upcoming months in iOS and Android calendars. These ads often cost their victims money by sending premium rate SMS messages, subscribing to unnecessary services, or downloading Android banking trojans, SMS trojans and malicious applications. Additionally, the malware uses URL shortener services to create links to ads, which in some cases monetize their clicks.

Based on ESET telemetry, Android/FakeAdBlocker was spotted for the first time in September 2019, and from January 1 to July 1, 2021, more than 150,000 instances of this threat were downloaded to Android devices. The most affected countries are Ukraine, Kazakhstan, Russia, Vietnam, India, Mexico, and the United States. Although in most cases the malware displays aggressive ads, ESET has identified hundreds of cases in which different malicious payloads were downloaded and executed, including the Cerberus banking trojan, which was variously disguised as Chrome, Android Update, Adobe Flash Player, or Update Android, and downloaded to devices in Turkey, Poland, Spain, Greece, and Italy. ESET also saw the Ginp trojan being downloaded in Greece and the Middle East.

“Based on our telemetry, it appears that many users tend to download Android apps from outside Google Play, which might lead them to download malicious apps delivered through aggressive advertising practices that are used to generate revenue for their authors,” explains ESET researcher Lukáš Štefanko, who analyzed Android/FakeAdBlocker. Commenting on the monetization of the shortened URL links, Štefanko adds, “When someone clicks on such a link, an advertisement will be displayed that will generate revenue for the person who generated the shortened URL. The problem is that some of these link shortener services use aggressive advertising techniques such as scareware ads informing users their devices are infected with dangerous malware.”

ESET Research has identified link shortener services pushing events to iOS calendars and distributing the Android/FakeAdBlocker malware that can be launched on Android devices. On iOS devices, besides flooding victims with unwanted ads, these links can create events in victims’ calendars by automatically downloading an ICS calendar file.

“It creates 18 events happening every day, each of which lasts 10 minutes,” says Štefanko. “Their names and descriptions suggest that the victim’s smartphone is infected, the victim’s data is exposed online, or a virus protection app has expired. Descriptions of each event include a link that leads the victim to visit a scareware advertisement website. That website again claims the device has been infected and offers the user an option to download shady cleaner applications from Google Play.”

For victims using Android devices, the situation is more dangerous because these scam websites may provide a malicious app to download from outside the Google Play store. In one scenario, the website requests to download an application called “adBLOCK,” which has nothing to do with the legitimate application and indeed does the opposite of blocking ads. In another scenario, when the victims proceed to download the requested file, they are shown a web page describing the steps to download and install a malicious application with the name “Your File Is Ready To Download.” In both scenarios, a scareware advertisement, or the Android/FakeAdBlocker trojan, is delivered via a URL shortener service.

For more technical details, and to learn how to uninstall Android/FakeAdBlocker, read the blog post “Some URL shortener services distribute Android malware, including banking or SMS trojans” on WeLiveSecurity. Make sure to follow ESET Research on Twitter for the latest news from ESET Research.

Common Questions about Privileged Access Management (PAM) Solutions

With technology increasingly present in our lives, ensuring the security of your company’s information has become a must. The market offers numerous tools to prevent cyberattacks and control internal access to sensitive data. One of the most efficient solutions we have is Privileged Access Management – PAM. See below some of the most common questions when looking for a practical and really efficient solution to protect your company:

What Are Privileged Accounts?

All the time, malicious people appear looking for flaws within the companies’ systems to gain access to confidential data. This threat can be both external and internal. Therefore, organizations are increasingly looking for solutions that are truly capable of protecting this information.

Privileged accounts are created to control access to this data. This access is usually restricted only to people who hold leadership positions (high-level management) and administrators in the IT area. Other employees can obtain this information with the authorization of the company. Although it is extremely important, proper control often ends up being flawed. Because of that, there is this need to have a tool really capable of directing, tracking, and filtering these accesses. Among the most efficient, we have PAM solutions.

Why Should I Invest in a PAM Solution?

Lack of control over access to certain data within an enterprise can result in major disruptions, including loss of business continuity. Many adopted systems end up vulnerable due to a lack of effective supervision.

This lack of control leaves room for the leak of information, much of it sensitive, inside or outside the company. But after all, how to guarantee the privacy of these contents?

The PAM solutions turn out to be quite efficient in this case, as they use security strategies and technologies that, together, are capable of controlling privileged access.

Moreover, they restrict which users will be allowed to enter certain accounts, applications, devices, processes, and internal systems, and control them. This prevents external attacks, which can occur as a result of an employee’s lack of attention, or sharing of sensitive information within the company.

To better understand how this management is done, we made a post explaining everything about PAM solutions. Are PAM Solutions Really Secure?

We often associate external attacks as our only risk. However, insider threats can also put an entire organization at risk.

They are not always associated only with the people who work in a company. In this list, we can also include service providers, such as consultants, third parties and suppliers, and even former employees, who may have access to its data even after leaving the company.

Improper access can result in damage caused intentionally or accidentally. No matter the reason, in all cases the consequences can be quite bad and even irreversible.

Therefore, it is common for people to have doubts whether a PAM solution is capable of filtering these people’s access. And the answer to that question is yes! It is so secure that they are recommended by cybersecurity experts. Gartner, for example, has chosen PAM as the number-1 security project for 2 years in a row.

When it comes to reducing risk within an organization, a PAM solution is considered one of the most efficient and indispensable. It is worth mentioning that it is always important to hire credible solutions from the market.

senhasegura, for example, offers really efficient solutions, which protect the customer from possible data theft, in addition to tracking the actions of administrators on networks, servers, databases, and devices. All of this is done in compliance with demanding global standards such as ISO 27001, PCI DSS, HIPAA, and Sarbanes-Oxley.

How Does it Reduce Insider Threats?

The PAM solution uses some features to mitigate insider and external threats. One is by protecting the credentials of your most confidential data in a central, secure vault to which few people (with permission) have access.

Privileged access can be limited so that only authorized people can consult personal customer data, trade secrets, ongoing negotiations, intellectual property, financial data, among others.

Privileged Access Management is able to direct which access each employee will have authorization. Thus, they will only be able to consult information relevant to their tasks. All of this will be controlled by the system, no matter if they are working in person or remotely.

In addition to internal data, in order to have greater control over protection against attacks, it is also possible to restrict access to external content on websites and applications that pose a certain type of threat to a company’s security.

Is It Possible to Protect My Passwords in The Cloud?

Yes. senhasegura is the only company in Brazil that offers a cloud-native password vault. The SaaS service protects your credentials, offers password rotation, auditing, and monitoring of these privileged accounts.

In this way, you minimize the duties of the security administrative department and allow the process to take place efficiently and at a lower cost. Therefore, it is ideal for small and medium-sized companies due to its advantages.

Is PAM The Same Thing As IAM?

No. Although both have the principle of controlling a company’s data, the two usually work in a complementary way, each with its own functionality.

In comparison, we can say that PAM is a little more elaborate. Identity and Access Management (IAM) is a tool used for administrators to easily manage users and legitimize access to certain company resources.

Despite that, this type of system has some gaps when it comes to privileged accounts. It is at this point that PAM becomes essential, as it works in a broader and more detailed way. This solution can inform you of everything that is being done, which sessions were started, and who is accessing certain information.

In short, a PAM solution controls everything related to this data within the company, managing to filter accessibility and ensure secure storage of all information.

Do you have any more questions on the subject? Get in touch with the senhasegura team, as we can help you find the ideal product for your needs.

Ensuring your company’s security does not have to be a concern anymore. We are sure of that, as we are experts when it comes to PAM Solution. Visit our website and learn more about all our products and services.
