Microsoft has shipped an emergency security update affecting most Windows users. This update partially addresses a security vulnerability known as PrintNightmare that could allow remote hackers to take over your system.
PrintNightmare could allow hackers to gain control of your computer. This means hackers could perform malicious activities like installing their own apps, stealing your data, and creating new user accounts.
Microsoft recommends Windows 10, 8.1, and 7 users update their computers through Windows Update as soon as possible. Note that an additional patch will likely be required to fully fix the issue, so expect another update prompt from Microsoft in the days to come.
For extra protection against malware that may result from a hack like this one, we recommend an all-in-one security solution, like McAfee Total Protection or McAfee LiveSafe. If a hacker takes advantage of the exploit and tries to install additional malware, McAfee Total Protection/LiveSafe can help protect against those attempts. Learn more about our online security products here.
PrintNightmare exploits a vulnerability in the Windows Print Spooler service. The step-by-step instructions below will guide you through turning off the service to ensure hackers can no longer exploit the security flaw. The Print Spooler will remain off until the PC is rebooted.
Step 1: Press the Windows key, and type Services, clicking on the Services App
Step 2: Scroll down to the Print Spooler Service
Step 3: Right-click on the Print Spooler Service and click Stop.

Microsoft today released updates to fix at least 74 separate security problems in its Windows operating systems and related software. This month’s patch batch includes fixes for seven “critical” flaws, as well as a zero-day vulnerability that affects all supported versions of Windows.
By all accounts, the most urgent bug Microsoft addressed this month is CVE-2022-26925, a weakness in a central component of Windows security (the “Local Security Authority” process within Windows). CVE-2022-26925 was publicly disclosed prior to today, and Microsoft says it is now actively being exploited in the wild. The flaw affects Windows 7 through 10 and Windows Server 2008 through 2022.
Greg Wiseman, product manager for Rapid7, said Microsoft has rated this vulnerability as important and assigned it a CVSS (danger) score of 8.1 (10 being the worst), although Microsoft notes that the CVSS score can be as high as 9.8 in certain situations.
“This allows attackers to perform a man-in-the-middle attack to force domain controllers to authenticate to the attacker using NTLM authentication,” Wiseman said. “This is very bad news when used in conjunction with an NTLM relay attack, potentially leading to remote code execution. This bug affects all supported versions of Windows, but Domain Controllers should be patched on a priority basis before updating other servers.”
Wiseman said the most recent time Microsoft patched a similar vulnerability — last August in CVE-2021-36942 — it was also being exploited in the wild under the name “PetitPotam.”
“CVE-2021-36942 was so bad it made CISA’s catalog of Known Exploited Vulnerabilities,” Wiseman said.
Seven of the flaws fixed today earned Microsoft’s most-dire “critical” label, which it assigns to vulnerabilities that can be exploited by malware or miscreants to remotely compromise a vulnerable Windows system without any help from the user.
Among those is CVE-2022-26937, which carries a CVSS score of 9.8, and affects services using the Windows Network File System (NFS). Trend Micro’s Zero Day Initiative notes that this bug could allow remote, unauthenticated attackers to execute code in the context of the Network File System (NFS) service on affected systems.
“NFS isn’t on by default, but it’s prevalent in environment where Windows systems are mixed with other OSes such as Linux or Unix,” ZDI’s Dustin Childs wrote. “If this describes your environment, you should definitely test and deploy this patch quickly.”
Once again, this month’s Patch Tuesday is sponsored by Windows Print Spooler, a core Windows service that keeps spooling out the security hits. May’s patches include four fixes for Print Spooler, including two information disclosure and two elevation of privilege flaws.
“All of the flaws are rated as important, and two of the three are considered more likely to be exploited,” said Satnam Narang, staff research engineer at Tenable. “Windows Print Spooler continues to remain a valuable target for attackers since PrintNightmare was disclosed nearly a year ago. Elevation of Privilege flaws in particular should be carefully prioritized, as we’ve seen ransomware groups like Conti favor them as part of its playbook.”
Other Windows components that received patches this month include .NET and Visual Studio, Microsoft Edge (Chromium-based), Microsoft Exchange Server, Office, Windows Hyper-V, Windows Authentication Methods, BitLocker, Remote Desktop Client, and Windows Point-to-Point Tunneling Protocol.
Also today, Adobe issued five security bulletins to address at least 18 flaws in Adobe CloudFusion, Framemaker, InCopy, InDesign, and Adobe Character Animator. Adobe said it is not aware of any exploits in the wild for any of the issues addressed in today’s updates.
For a more granular look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the skinny on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these patches, please drop a note about it here in the comments.
At Cisco Duo, we continually strive to enhance our products to make it easy for security practitioners to apply access policies based on the principles of zero trust. This blog highlights how Duo is achieving that goal by simplifying user and administrator experience and supporting data sovereignty requirements for customers around the world. Read on to get an overview of what we have been delivering to our customers in those areas in the past few months.
Duo strives to make secure access frictionless for employees while reducing the administrative burden on IT (Information Technology) and helpdesk teams. This is made possible thanks to the strong relationship between our customers and our user research team. The insights we gained helped us implement some exciting enhancements to Duo Single Sign-On (SSO) and Device Trust capabilities.
Duo SSO unifies identities across systems and reduces the number of credentials a user must remember and enter to gain access to resources. Active Directory (AD) is the most popular authentication source connected to Duo SSO, accounting for almost 80% of all setups. To make Duo’s integration with AD even easier to implement, we have introduced Duo SSO support for multiple Active Directory forests for organizations that have users in multiple domains. Additionally, we added the Expired Password Resets feature in Duo SSO. It provides an easy experience for users to quickly reset their expired Active Directory password, log into their application, and carry on with their day. Continuing the theme of self service, we introduced a hosted device management portal – a highly requested feature from customers. Now administrators no longer need to host and manage the portal, and end users can login with Duo SSO to manage their authentication devices (e.g.: TouchID, security keys, mobile phone etc.) without needing to open IT helpdesk tickets.
We are also simplifying the administrator experience. We have made it easy for administrators to configure Duo SSO with Microsoft 365 using an out of the box integration. Duo SSO layers Duo’s strong authentication and flexible policy engine on top of Microsoft 365 logins. Further, we have heard from many customers that they want to deliver a seamless on-brand login experience for their workforce. To support this, we have made custom branding so simple that administrators can quickly customize their end-user authentication experience from the settings page in the Duo Admin Panel.
Device Trust is a critical capability required to enable secure access for the modern workforce from any location. We have made it easy for organizations to adopt device trust and distinguish between managed and unmanaged devices. Organizations can enforce a Trusted Endpoint policy to allow access only from managed devices for critical applications. We have eliminated the requirement to deploy and manage device certificates to enforce this policy. Device Health application now checks the managed status of a device. This lowers administrative overhead while enabling organizations to achieve a better balance between security and usability. We have also added out-of-box integrations with unified endpoint management solutions such as Active Directory domain-joined devices, Microsoft Intune, Jamf Pro and VMware Workspace ONE. For organizations that have deployed a solution that is not listed above, Duo provides a Device API that works with any enterprise device management system.
To support our growing customer base around the world, Duo expanded its data center presence to Australia, Singapore, and Japan in September last year. And now Duo is thrilled to announce the launch of the two new data centers in the UK and India. Both the new and existing data centers will allow customers to meet all local requirements, all while maintaining ISO27001 and SOC2 compliance and a 99.999% service availability goal.
The launch of the new data centers is the backbone of Duo’s international expansion strategy. In the last two years, Duo has met key international growth milestones and completed the C5 attestation (Germany), AgID certification (Italy) and IRAP assessment (Australia) – all of which demonstrate that Duo meets the mandatory baseline standards for use by the public sector in the countries listed above. Check out this Privacy Data Sheet to learn more about Cisco Duo’s commitment to our customer’s data privacy and data sovereignty.
That is a summary of what we have been up to here at Cisco Duo in the past few months. But we are not done yet! Stay tuned for more exciting announcements at RSA Conference 2022 next week. Visit us at our booth at RSAC 2022 and World of solutions at Cisco Live 2022.
In the meanwhile, check out this on-demand #CiscoChat panel discussion with real-world security practitioners on how they have implemented secure access best practices for hybrid work using Duo. And if you do not want to wait, sign-up for a 30 day trial and experience how Duo can simplify secure access for your workforce.

Security that is hard to deploy and complex to manage needs to become a distant memory if businesses are to be resilient through times of uncertainty. Even something as critical as a firewall, the sentinel in the security stack, can often require a lengthy setup, ongoing maintenance, and disjointed management. Over the long run, these additional costs accrue and can have a negative impact on security programs. When budgets are constrained, these effects can be exacerbated and become a barrier to providing the level of security organizations need to protect the integrity of their business.
At Cisco we have a rich history overcoming this challenge with Cisco Secure Firewall. Forrester Consulting recently conducted an independent analysis of organizations using Secure Firewall. The study showed that customers realized a 195% in total ROI when managing their firewall fleet through Cisco Secure Firewall Management Center (FMC). Improvements to security workflows through the FMC, which include deploying, managing, and updating policy, were the largest contributing factor to the tune of $18.6 million in total benefits achieved. The Forrester study states that “organizations reduced network operation work streams by up to 95%. Thanks to the latest features of Cisco Secure Firewall and the ease of management via Firewall Management Center.”
We are not done. Today we boost productivity even further, with the new cloud-delivered version of FMC within the Cisco Defense Orchestrator (CDO) platform. This leap brings all the features from FMC into the cloud and consolidates firewall management. Organizations save time, increase security, and gain a positive ROI. With cloud-delivered FMC, manually managing updates is a thing of the past. An agile delivery of updates is built in to ensure uptime, so you can focus on your most important priorities — protecting the integrity of the business with increased firewall capabilities. The CDO platform unifies the lifecycle of policy management across multiple Cisco security solutions in our cloud. By bringing the FMC experience directly into CDO, end users enjoy the same look, functionality, and workflow as on-premises and virtual versions of Firewall Management Center. Without the usual learning curve within a new “experience,” migration to the cloud is simplified. Organizations can now propel cloud-first strategies and enable the rapid delivery of firewall services no matter where your network may roam.
“Moving FMC into CDO isn’t just about cost savings for today and powering security resilience with flexibility and choice. We are also putting a firm foot into the near future for SASE and achieving unified policy across the multienvironment IT.”– Justin Buchanan, Sr. Director Product Management, Cisco Secure
Traditionally, customers have deployed FMC as a physical or virtual appliance. Now in addition to cost savings, security resilience is driving an increased need for hybrid multicloud deployments. Leveraging public cloud infrastructures, organizations are becoming more cost efficient — cloud-delivered applications reduce change management and operational overhead. But they are also ensuring organizations have the agility required to deploy network security workloads where and how they want to remain agile and adapt to uncertainty.
Hybrid work and business continuity is made possible within the CDO platform. A cloud-based and centralized platform unifies firewall management across the Cisco Secure and Meraki portfolio and provides the foundation to unify policy across the distributed network all within a platform that is built to drive increased ROI and preserve the user experience. IT can control and manage firewall policy from anywhere along with a low-touch provisioning and onboarding process for branch and firewall deployments. The cloud-delivered FMC integrates with Cisco Secure Analytics & Logging, and, as a result, enhanced data retention and meeting stringent compliance requirements has never been easier. Whether you are part of a smaller organization or a larger enterprise, you control how many Cisco Secure Firewalls are managed through the cloud-delivered FMC, and easily scale that number. So, when it comes to simplicity at scale, CDO is your answer.

Microsoft on Tuesday released software updates to fix 60 security vulnerabilities in its Windows operating systems and other software, including a zero-day flaw in all supported Microsoft Office versions on all flavors of Windows that’s seen active exploitation for at least two months now. On a lighter note, Microsoft is officially retiring its Internet Explorer (IE) web browser, which turns 27 years old this year.
Three of the bugs tackled this month earned Microsoft’s most dire “critical” label, meaning they can be exploited remotely by malware or miscreants to seize complete control over a vulnerable system. On top of the critical heap this month is CVE-2022-30190, a vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows.
Dubbed “Follina,” the flaw became public knowledge on May 27, when a security researcher tweeted about a malicious Word document that had surprisingly low detection rates by antivirus products. Researchers soon learned that the malicious document was using a feature in Word to retrieve a HTML file from a remote server, and that HTML file in turn used MSDT to load code and execute PowerShell commands.
“What makes this new MS Word vulnerability unique is the fact that there are no macros exploited in this attack,” writes Mayuresh Dani, manager of threat research at Qualys. “Most malicious Word documents leverage the macro feature of the software to deliver their malicious payload. As a result, normal macro-based scanning methods will not work to detect Follina. All an attacker needs to do is lure a targeted user to download a Microsoft document or view an HTML file embedded with the malicious code.”
Kevin Beaumont, the researcher who gave Follina its name, penned a fairly damning account and timeline of Microsoft’s response to being alerted about the weakness. Beaumont says researchers in March 2021 told Microsoft they were able achieve the same exploit using Microsoft Teams as an example, and that Microsoft silently fixed the issue in Teams but did not patch MSDT in Windows or the attack vector in Microsoft Office.
Beaumont said other researchers on April 12, 2022 told Microsoft about active exploitation of the MSDT flaw, but Microsoft closed the ticket saying it wasn’t a security issue. Microsoft finally issued a CVE for the problem on May 30, the same day it released recommendations on how to mitigate the threat from the vulnerability.
Microsoft also is taking flak from security experts regarding a different set of flaws in its Azure cloud hosting platform. Orca Security said that back on January 4 it told Microsoft about a critical bug in Azure’s Synapse service that allowed attackers to obtain credentials to other workspaces, execute code, or leak customer credentials to data sources outside of Azure.
In an update to their research published Tuesday, Orca researchers said they were able to bypass Microsoft’s fix for the issue twice before the company put a working fix in place.
“In previous cases, vulnerabilities were fixed by the cloud providers within a few days of our disclosure to the affected vendor,” wrote Orca’s Avi Shua. “Based on our understanding of the architecture of the service, and our repeated bypasses of fixes, we think that the architecture contains underlying weaknesses that should be addressed with a more robust tenant separation mechanism. Until a better solution is implemented, we advise that all customers assess their usage of the service and refrain from storing sensitive data or keys in it.”
Amit Yoran, CEO of Tenable and a former U.S. cybersecurity czar, took Microsoft to task for silently patching an issue Tenable reported in the same Azure Synapse service.
“It was only after being told that we were going to go public, that their story changed…89 days after the initial vulnerability notification…when they privately acknowledged the severity of the security issue,” Yoran wrote in a post on LinkedIn. “To date, Microsoft customers have not been notified. Without timely and detailed disclosures, customers have no idea if they were, or are, vulnerable to attack…or if they fell victim to attack prior to a vulnerability being patched. And not notifying customers denies them the opportunity to look for evidence that they were or were not compromised, a grossly irresponsible policy.”
Also in the critical and notable stack this month is CVE-2022-30136, which is a remote code execution flaw in the Windows Network File System (NFS version 4.1) that earned a CVSS score of 9.8 (10 being the worst). Microsoft issued a very similar patch last month for vulnerabilities in NFS versions 2 and 3.
“This vulnerability could allow a remote attacker to execute privileged code on affected systems running NFS. On the surface, the only difference between the patches is that this month’s update fixes a bug in NFSV4.1, whereas last month’s bug only affected versions NSFV2.0 and NSFV3.0,” wrote Trend Micro’s Zero Day Initiative. “It’s not clear if this is a variant or a failed patch or a completely new issue. Regardless, enterprises running NFS should prioritize testing and deploying this fix.”
Beginning today, Microsoft will officially stop supporting most versions of its Internet Explorer Web browser, which was launched in August 1995. The IE desktop application will be disabled, and Windows users who wish to stick with a Microsoft browser are encouraged to move to Microsoft Edge with IE mode, which will be supported through at least 2029.

And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the dirt on any patches that may be causing problems for Windows users.

The past few months have been chockfull of conversations with security customers, partners, and industry leaders. After two years of virtual engagements, in-person events like our CISO Forum and Cisco Live as well as the industry’s RSA Conference underscore the power of face-to-face interactions. It’s a reminder of just how enriching conversations are and how incredibly interconnected the world is. And it’s only made closer by the security experiences that impact us all.
I had the pleasure of engaging with some of the industry’s best and brightest, sharing ideas, insights, and what keeps us up at night. The conversations offered more than an opportunity to reconnect and put faces with names. It was a chance to discuss some of the most critical cybersecurity issues and implications that are top of mind for organizations.
The collective sentiments are clear. The need for better security has never been so strong. Securing the future is good business. Disruptions are happening faster than ever before, making our interconnected world more unpredictable. Hybrid work is here to stay, hybrid and complex architectures will continue to be a reality for most organizations and that has dramatically expanded the threat surface. More and more businesses are operating as ecosystems—attacks have profound ripple effects across value chains. Attacks are becoming more bespoke, government-sponsored threat actors and ransomware as a service, continue to unravel challenging businesses to minimize the time from initial breach to complete compromise, in the event of a compromise.
Regardless of where organizations are on their digital transformations, they are progressively embarking upon journeys to unify networking and secure connectivity needs. Mobility, BYOD (bring your own device), cloud, increased collaboration, and the consumerization of IT have necessitated a new type of access control security–zero trust security. Supporting a modern enterprise across a distributed network and infrastructure involves the ability to validate user IDs, continuously verify authentication and device trust, and protect every application—
without compromising user experience. Zero trust offers organizations a simpler approach to securing access for everyone, from any device, anywhere—all the while, making it harder for attackers.
Simplicity continues to be a hot topic, and in the context of its functionality. In addition to a frictionless user experience, the real value to customers is improving operational challenges. Security practitioners want an easier way to secure the edge, access, and operations—including threat intelligence and response. Key to this simplified experience is connecting and managing business-critical control points and vulnerabilities, exchanging data, and contextualizing threat intelligence. And it requires a smarter ecosystem that brings together capabilities, unifying admin, policy, visibility, and control. Simplicity that works hard and smart—and enhances their security posture. The ultimate simplicity is improved efficacy for the organization.
Insider cyber-attacks are among the fastest growing threats in the modern security network, an increasingly common cause of data breaches. Using their authorized access, employees are intentionally or inadvertently causing harm by stealing, exposing, or destroying sensitive company data. Regardless, the consequences are the same—costing companies big bucks and massive disruption. It’s also one of the reasons why “identity as the new perimeter” is trending, as the primary objective of all advanced attacks is to gain privileged credentials. Insider attack attempts are not slowing down. However, advanced telemetry, threat detection and protection, and continuous trusted access all help decelerate the trend. Organizations are better able to expose suspicious or malicious activities caused by insider threats. Innovations are enabling business to analyze all network traffic and historical patterns of employee access and determine whether to let an employee continue uninterrupted or prompt to authenticate again.
Supply chain attacks have become one of the biggest security worries for businesses. Not only are disruptions debilitating, but no one knew the impacts or perceived outcomes. Attackers are highly aware that supply chains are comprised of larger entities often tightly connected to a broad array of smaller and less cyber-savvy organizations. Lured by lucrative payouts, attackers seek the weakest supply chain link for a successful breach. In fact, two of the four biggest cyber-attacks that the Cisco Talos team saw in the field last year were supply chain attacks that deployed ransomware on their targets’ networks: SolarWinds and REvil’s attack exploiting the Kaseya managed service provider. While there’s no perfect way to absolutely protect from ransomware, businesses are taking steps to bolster their defenses and protect against disaster.
Security incidents targeting personal information are on the rise. In fact, 86 percent of global consumers were victims of identity theft, credit/debit card fraud, or a data breach in 2020. In a recent engagement discovered by the Cisco Talos team, the API on a customer’s website could have been exploited by an attacker to steal sensitive personal information. The good news is governments and businesses alike are leaning into Data Privacy and Protection, adhering to global regulations that enforce high standards for collecting, using, disclosing, storing, securing, accessing, transferring, and processing personal data. Within the past year, the U.S. government implemented new rules to ensure companies and federal agencies follow required cybersecurity standards. As long as cyber criminals continue seeking to breach our privacy and data, these rules help hold us accountable.
Through all the insightful discussions with customers, partners, and industry leaders, a theme emerged. When it comes to cybersecurity, preparation is key and the cost of being wrong is extraordinary. By acknowledging there will continue to be disruptions, business can prepare for whatever comes next. And when it comes, they’ll not only weather the storm, but they will also come out of it stronger. And the good news is that Cisco Security Business Group is already on the journey actively addressing these headlines, and empowering our customers to reach their full potential, securely.
