If you are still using Windows Server 2003 or XP, Windows 7, Windows 2008 R2, or Windows 2008 you could be in trouble. A wormable virus may be coming your way. The virus is designated as CVE-2019-0708.
This means that the virus can get into your system without you doing anything like clicking a malicious link. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights without your knowledge.
What Should You Do?
Microsoft has released a critical update for their Remote Desktop Services that impacts multiple Windows versions. The patches are for devices and systems that are both in and out-of-support, which is rare for Microsoft to do. This shows the importance of these patches.
The update addresses the vulnerability by correcting how Remote Desktop Services handles connection requests. To apply the patches, go to the Microsoft Security Update Guide for in-support systems and KB4500705 for out-of-support systems.
Note: Clients & Customers on a valid managed services agreement are being taken care of and there is no immediate action for any computer, server or other devices under a valid managed services agreement.
Microsoft recommends that customers running one of these operating systems download and install the update as soon as possible.
Does This Mean Even Systems Without Support Can Get The Patch?
Yes, Microsoft is aware that some customers are running versions of Windows that no longer receive mainstream support. This means that you wouldn’t have received any security updates to protect your systems from the CVE-2019-0708 virus.
Given the potential impact on customers and their businesses, Microsoft decided to make security updates available for platforms that are no longer in mainstream support.
All Windows updates are available from the Microsoft Update Catalog.
What Should We Do Before We Apply The Update?
It’s recommended that you back up all of your important data first. If you have a reliable backup, if the patch creates problems you can still access your data. You should do this before you install any patches.
What If We Can’t Apply The Patches?
If you can’t apply the patch for your system there are other things that you can do:
- If you don’t need the Remote Desktop Services, you can disable it.
- Block the TCP port 3389 (this prevents unauthorized requests from the Internet).
- Enable NLA (Network Level Authentication) for Windows 7 and Windows Server 2008.
Of course, the best thing to do is to contact your local IT services company. They’ll know exactly what to do.
What Is A Wormable Virus?
This means that any future malware that uses this vulnerability could propagate from one vulnerable computer to another. This is how similar malware like WannaCry spread around the world. Experts are worried that this flaw could be used to fuel a fast-moving malware threat like the WannaCry ransomware attacks of 2017.
Here’s what Simon Pope, director of incident response for the Microsoft Security Response Center tells us:
“This vulnerability is pre-authentication and requires no user interaction,” Pope said. “In other words, the vulnerability is ‘wormable,’ meaning that any future malware that exploits this vulnerability could propagate from vulnerable computer to vulnerable computer in a similar way as the WannaCry malware spread across the globe in 2017. It is important that affected systems are patched as quickly as possible to prevent such a scenario from happening.”
Have There Been Any Attacks Yet?
Microsoft said they haven’t found evidence of attacks against this dangerous security flaw. But one could happen at any time. Right now they are trying to prevent a serious, imminent threat with these patches.
Simon Pope goes on to say:
“While we have observed no exploitation of this vulnerability, it is highly likely that malicious actors will write an exploit for this vulnerability and incorporate it into their malware.”
What Does The Microsoft Remote Desktop Do?
You use the Microsoft Remote Desktop application to connect to a remote PC or virtual apps and desktops made available by your admin. You can control your desktop computer and all of its contents from another computer.
The app lets you connect to your desktop from wherever you are. The access to the remote desktop happens over the Internet or via another network. It lets you interact as if you were physically working from your desktop.
The Remote Desktop application also gives the “master” computer access to all of the contents on the remote computer.
What Else Should We Know?
If you had updated from Windows 7 to Windows 10 or from Windows Servers 2008/2008 R2 to Windows Server 2016 or 2019, you wouldn’t need to worry. This is why it’s essential to keep your systems up to date.
Soon, on January 14, 2020, support will come to an end for all Windows Server 2008, 2008 R2 equipment and the Windows 7 operating system.
If you’re still using these servers or operating system, it’s crucial to replace them now so that there’s no disruption to your daily operations or loss of data.
Any hardware or software product that reaches its end of life is a potential gateway for hackers to enter through. In addition to the security hazard, there are other reasons why it isn’t a good idea to keep using old equipment such as unresolvable outages.

Microsoft began notifying Outlook.com users of a 2019 security breach that occurred between January 1st and March 28th. Hackers were unintentionally given unauthorized access to some accounts, where they were then able to view subject lines, email addresses, and folder names. While no login details—including passwords—were directly accessed as part of this breach, Microsoft did warn users to reset their passwords.
Although the hackers could not view the actual content in the bodies of emails nor download attachments, this incident still represents a major—and disturbing—security incident. This breach serves as a reminder to every business to tighten up its security measures and protect its assets.
Use multi-factor authentication.
Do not leave this as an optional measure for your employees; require it. Multi-factor authentication uses more than one form of identity confirmation—this is the “multi-factor”—to prove the identity of the person attempting to access a particular platform—this is the “authentication.”
Depending on where in the product the Microsoft breach happened, multi-factor authentication could even have possibly prevented or limited the breach. In general, this authentication process adds a strong layer of security. Hackers don’t usually have both the password and the PIN, secret questions, or other ability to verify their identity.
When vetting which type of authentication to implement—if you have this option—consider using the one that is easiest for employees to have on hand, but hardest for others to get a hold of. Trying to make this relatively convenient for your employees will make it easier for them to comply, which will keep your business more secure. Multi-factor authentication is a measure that should go hand-in-hand with training your employees to use strong passwords.
Account for all devices—including mobile—in your security processes.
Very few companies still limit employee access to business assets strictly to desktops at work. There is a growing trend of employees being able to work remotely, even if it is not full-time. A recent study showed that as many as 70% of employees work remotely at least once a week. Whether working from home, a rented office space, or on-the-road, they are using their devices to log in from a distance, well beyond the secured confines of your office. This figure was accounting for full-time employees; contractors only increase the number of remote workers further.
The security processes implemented at your company needs to account for how all of your employees are accessing company resources. Email access on mobile devices is one of the most common ways in which employees take their work on-the-go, and so it’s a strong starting point for building out these protocols. Because confidential company information is being accessed on these devices via networks over which companies have no control, it is critical that both the email servers as well as the devices being used have robust security systems in place.
While new improvements continue to roll out to tackle these issues, solutions that work across all devices are the norm. Security software, as well as encryption tools, can help protect data regardless of the device, particularly when combined with encouraging employees to log-in via secure VPN networks. Cloud options for data storage are offered by providers with a menu of security options; it’s worth walking through your needs and investing in top-quality solutions.
Document your security processes.
With all of the work that goes into developing security processes, even more needs to be carried out to maintain their implementation and ensure that they remain up-to-date with new tech trends and emerging risks.
This is a vast and complex undertaking. All existing assets must be brought onto any updated infrastructure. Employees must be set-up for and onboarded to the security procedures, and checkpoints must be established so that their compliance may be monitored. Systems must be monitored for any breaches, as well as smoothly updated across all users and data to accommodate any new vulnerabilities that arose since the previous update. Different components, whether hardware (including different devices, such as mobile) or software, may experience issues with any updates. New members of the internal information technology must be introduced to the systems while existing members must stay abreast of any new developments; even team members working simultaneously on the same project must address potential communications issues.
Thorough documentation of processes helps achieve this by providing an objective record of the systems in place. This can be used for onboarding; for internal audits; for evaluating alternatives or potential improvements; and even for reviewing the source of vulnerabilities and providing accountability should an issue arise. This sort of record-keeping is an essential component of transparency in company policy and helps enforce quality control on internal processes. Of course, it must also be protected with the highest measure of security since it arguably contains “the keys to the castle.” Decentralizing its storage and scattering protected, encrypted components of it across multiple storage solutions can help protect company assets from the sort of large-scale breach that could otherwise bring your data assets to their knees.
And so, the large-scale Microsoft breach serves as a reminder that active vigilance must always be maintained over internet security, without relying entirely on one single individual, provider, or service. No single entity can be trusted to be entirely safe when major players like Microsoft are clearly vulnerable, despite the teams of brilliant engineers hired to implement safeguards and the millions of dollars invested in diverse preventive measures. Every business needs to be proactive in protecting itself through rigorous internal standards, ranging from staff training through the implementation of mandatory security precautions, to minimize the risk of vulnerabilities being exposed and exploited. Factoring in every employees’ data paths and employing multiple layers of overlapping security efforts at every step of the way—and documenting these processes for easy internal accountability and refinement—are critical for business informational security in this highly connected digital age.
Firewalls were developed over thirty years ago and function as the first line of defense for many business networks. This piece of network equipment is a perimeter defense that determines whether packets can move into or out of the network. While the basic concept of a firewall is simple, the way that it performs this function and the features it offers continue to evolve based on current threats.
Types of Firewalls
Firewalls come in two major categories: hardware and software. The physical firewalls are network appliances that connect to the rest of the IT infrastructure so it’s able to monitor packets. There are several methods they can use to secure the network and assist with thwarting potential intruders.
Stateful firewalls retain information about the connections being made. It offers good performance because this technology allows it to skip inspecting every single packet. Once it has inspected a connection, it allows it for subsequent packets.
Application-level firewalls that are hardware based are designed to protect the application’s connections. They address common attack methods used on that type of application, such as stopping cross-site scripting for a web application.
When someone thinks about a standard firewall, a proxy firewall is most likely what’s on their mind. It stands between a host device and the data source and inspects the packets that are sent between them. This type of firewall may not stand up to complex attacks due to its simplicity, but it masks a lot of the network information.
This firewall is another basic one that focuses on checking the TCP handshake. It’s not resource intensive since it doesn’t look at the packet, but that does mean that it won’t protect against sophisticated attacks.
These firewalls have advanced features that give businesses more ways to stop malicious traffic from making it through the appliance. Some examples of these include deep packet inspection, checking attachments in sandboxes, and terminating encrypted traffic. Third-party data can be incorporated into the rules and filters of the firewall to improve protection against emerging threats. They can also incorporate technology that is found in other types of IT security hardware, such as intrusion detection. The drawback of this firewall type is that it can significantly slow down network traffic.
This firewall is a software package that’s installed on the business network and does not rely on a hardware appliance for protecting traffic.
Some applications have firewalls built into the software itself to act as a second layer of protection. Anything that gets through the physical firewall of the business network and reaches the application layer needs to go through another inspection. These firewalls focus on threats that are most common for that piece of software.
A cloud-based firewall leverages cloud computing technology for the virtual appliance. Some advantages of a cloud firewall include the ability to scale quickly, high availability, and cost-efficiency. For organizations with limited IT budgets, using a cloud-based service can give them access to powerful features that they wouldn’t have access to without paying a substantial upfront hardware fee.
The right firewall for your organization depends on the typical threats that you face, the sensitivity of the information you’re protecting, and your performance requirements.
Did you know? Microsoft is ending support for Windows 7 in January 2020. Beginning this April, Microsoft will start displaying pop-ups on all Windows 7 computers alerting the users that their support for Windows 7 will be ending.
Don’t be alarmed. Microsoft also did the same thing with Windows XP before shutting down their support for the Windows XP Operating System.

TrickBot is up to its tricks again. Once cyber experts get a handle on it, TrickBot releases new modules that advance its capabilities. Here’s what you need to know to protect your organization from TrickBot.
Don’t Get Tricked By TrickBot
TrickBot is up to its tricks again. Once cyber experts get a handle on it, TrickBot releases new modules that advance its capabilities. Here’s what you need to know to protect your organization from TrickBot.
What Is TrickBot?
The Multi-State Information Sharing and Analysis Center (MS-ISAC) recently released a security primer on TrickBot. Originally developed in 2016 as a Windows-based banking Trojan, TrickBot has recently advanced its capabilities.
TrickBot is a modular banking trojan that targets user financial information and acts as a vehicle for other malware. It uses Man-in-the-Browser attacks to steal financial information such as login credentials for online banking sessions. (The majority of financial institutions consider Man In The Browser attacks as the greatest threat to online banking.)
Malware developers are continuously releasing new modules and versions of TrickBot— And they’ve done this once again.
How Is TrickBot Distributed?
TrickBot is disseminated via malspam campaigns. Malspam is a combination of malware and spam. It’s usually delivered through phishing or spear-phishing emails. Its goal is to exploit computers for financial gain.
These malspam campaigns send unsolicited emails that direct users to download malware from malicious websites or trick the user into opening malware through an attachment.
TrickBot is also dropped as a secondary payload by other malware such as Emotet. Some of TrickBot’s modules abuse the Server Message Block (SMB) Protocol to spread the malware laterally across a network. (SMB is an application-layer network protocol that facilitates network communication while providing shared access to client files, printers and serial ports.)
The developers behind TrickBot have continue to add more features via modules to this potent trojan virus. It can download new modules that allow it to evolve if left unchecked.
How Does The TrickBot Malspam Campaign Work?
The malspam campaigns that deliver TrickBot use third-party branding looks familiar to you and your staff such as invoices from accounting and financial firms. The emails typically include an attachment, such as a Microsoft Word or Excel document. If you open the attachment, it will execute and run a script to download the TrickBot malware.
And, TrickBot is really tricky. It runs checks to ensure that it isn’t put in a sandboxed (quarantined) environment. Then it attempts to disable your antivirus programs like Microsoft’s Windows Defender.
And even worse, TrickBot redeploys itself in the “%AppData%” folder and creates a scheduled task that provides persistence. Persistence is the continuance of the effect after its cause is removed. So, even after you remove TrickBot, it can still create problems.
What Happens If Your Network Gets Infected With TrickBot?
TrickBot’s modules steal banking information, perform system/network reconnaissance, harvest credentials and can propagate throughout your network.
- Will harvest your system information so that the attacker knows what’s running on your network.
- Compares all files on your disk against a list of file extensions.
- Collects more system information and maps out your network.
- Harvests browser data such as cookies and browser configurations.
- Steals credentials and configuration data from domain controllers.
- Auto fills data, history, and other information from browsers as well as software applications.
- Accesses saved Microsoft Outlook credentials by querying several registry keys.
- Force-enables authentication and scrapes credentials.
- Uses these credentials to spread TrickBot laterally across your networks.
What’s New With TrickBot?
In November 2018, a module was developed and added that gave TrickBot the ability to steal credentials from popular applications such as Filezilla, Microsoft Outlook, and WinSCP.
In January 2019, three new applications were targeted for credential grabbing: VNC, Putty, and RDP.
In addition, it can also steal credentials and artifacts from multiple web browsers (Google Chrome/Mozilla Firefox/Internet Explorer/Microsoft Edge) including your browsing history, cookies, autofills, and HTTP Posts.
How Can You Protect Your Organization From TrickBot?
We recommend that you contact us and arrange for the following to protect against the TrickBot malware:
- Implement filters at the email gateway to filter out emails with known malspam indicators such as known malicious subject lines, and block suspicious IP addresses at the firewall.
- Use managed antivirus programs on clients and servers, with automatic updates of signatures and software. Off-the-shelf antivirus isn’t enough.
- Arrange for vulnerability scans to detect TrickBot or other malware threats that are hiding in your IT systems.
- Apply appropriate patches and updates immediately after they are released.
- Provide Security Awareness Training for your users. Regular training will ensure that they can recognize social engineering/phishing attempts, and refrain from opening attachments from unverified senders.
- Help you employ a Password Management solution so your usernames and passwords aren’t disclosed to unsolicited requests.
- Deploy a managed Anti-Spam/Malware Solution with the latest signature and detection rules.
- Review security logs for indicators of TrickBot. If any are found, we can isolate the host and begin investigation and remediation procedures.
- Make sure you adhere to the principle of least privilege, ensuring that users have the minimum level of access required to accomplish their duties. We’ll also limit administrative credentials to designated administrators.
- Implement Domain-Based Message Authentication, Reporting & Conformance (DMARC). This is a validation system that minimizes spam emails by detecting email spoofing using Domain Name System (DNS) records and digital signatures.
- If you don’t have a policy regarding suspicious emails, we can help you create one and specify that all suspicious emails should be reported to security and/or IT departments.
- And more…
