All through the previous few years, Microsoft has confronted a slew of negative news over a sequence of vulnerabilities and hacks. So, it’s no marvel that vulnerabilities in Microsoft merchandise are a pretty assault vector. Based on a report from the Cybersecurity and Infrastructure Safety Company (CISA), Microsoft programs has had 238 cybersecurity deficiencies reported for the reason that starting of 2022, which is 30% of all vulnerabilities found up to now this yr.
In 2021, main businesses just like the Nationwide Safety Company (NSA), FBI, CISA and CIA detailed the 15 most common vulnerabilities and exposures (CVEs) exploited by hackers. Of these, 60% (9) have been on account of deficiencies in Microsoft’s designed, operated and owned programs, together with seven CVEs inside Microsoft’s Change Server.
That is much more alarming when you think about that Microsoft holds a dominant share (85%) of U.S. authorities office procurement and IT programs, basically placing your complete authorities prone to a hack.
Microsoft made headlines again in late 2021, when it warned clients that the Azure cloud platform had configuration errors in a element which, enabled by default, had uncovered information for the previous two years. Consequently, hundreds of shoppers that depend on the Azure Cosmos DB — together with family names like Exxon and Coca-Cola, have been uncovered to the likelihood that an attacker might learn, write or delete information with out authorization.

Menace actors exploited a number of yet-to-be-disclosed Microsoft flaws and zero-day bugs, permitting assaults to be executed remotely, in keeping with claims made by safety researchers at Vietnamese cybersecurity outfit GTSC, who first noticed and reported that attackers have been chaining the pair of zero-days to deploy Chinese language Chopper net shells on compromised servers for persistence and information theft.
As a result of fixed hacks and vulnerabilities found inside Microsoft’s product ecosystem, different contemporaries, comparable to Google, at the moment are supposedly overtaking the safety innovation house. Lately, at its Cloud Subsequent ’22 occasion, Google introduced a Rapid Vulnerability Detection service. The instrument is a zero-configuration service in Safety Command Middle Premium that detects vulnerabilities like uncovered admin interfaces, weak credentials and incomplete software program installations.
As a family identify and a tech large, the place do Microsoft’s cybersecurity practices lack? And what does the way forward for such threats appear like?
The good vulnerability shark
All through the previous 15 years, Microsoft has made progress in hardening the Home windows kernel, the working system’s (OS) core that hackers should successfully handle to manage a machine. Introducing stringent new limits on loading system drivers that might function in kernel mode was a cornerstone of that improvement.
In February 2019, software program firm SolarWinds was attacked by suspected nation-state hackers often known as Nobelium. The group gained entry to hundreds of SolarWinds clients’ networks, programs and information, ensuing within the largest hack ever recorded. Furthermore, following a Reuters exclusive on December 17, 2020, it grew to become obvious that individual Microsoft-specific vulnerabilities exacerbated the injury within the SolarWinds assault.
Andrew Grotto, former White Home director of cyber coverage, says that part of such assaults lies in a legacy codebase downside.
“Microsoft merchandise require a lot effort to configure the proper manner and, on account of such configuration issues, the merchandise are weak to exploitation,” he stated.
“For Microsoft programs that SolarWinds clients have been utilizing, the attackers burrowed deeper and deeper into the sufferer’s networks and took benefit of configuration issues in Microsoft’s merchandise,” Grotto advised VentureBeat.
This was only the start, as in March 2021, a bunch of hackers collectively often known as Hafnium have been capable of exploit weaknesses in Microsoft’s Change software program, permitting Hafnium to take management of servers and achieve entry to delicate company and governmental group data.
The FBI wanted to hack into a whole bunch of pc servers of U.S. firms to take away the Hafnium malware. Microsoft launched a patch to repair 114 vital vulnerabilities in April 2021.
Equally, in March 2022, Microsoft introduced that it was breached by the prison hacker group Lapsus$, explaining that the group compromised one in every of its accounts, which gave the group “restricted entry” to firm information. Nevertheless, the corporate denied that the group obtained information of any Microsoft clients.
The corporate would later acknowledge that the group stole components of the supply code related to a few of Microsoft’s merchandise. Lapsus$ claimed to have gotten supply code for the Bing search engine and Cortana voice assistant. (Nevertheless, Microsoft claimed that it didn’t depend on the secrecy of its supply code as a safety measure.)
Dan Schiappa, chief product officer at Arctic Wolf and ex-Microsoft safety govt, defined that Microsoft’s code is commonly a mixture of previous and new, making it much more difficult for them to make sure there are not any vulnerabilities.
“I believe it can take the cybersecurity ecosystem to assist shield Microsoft’s huge know-how base. Microsoft will proceed to make incremental adjustments to enhance their safety posture, however I don’t consider they are going to do something that can considerably scale back the danger,” he stated. “Consequently, having the right safety portfolio or service is one of the simplest ways to make sure you have Microsoft safety lined.”
Microsoft’s product ecosystem bottleneck
As a dominant enterprise vendor available on the market, risk actors have been working across the clock to focus on and exploit merchandise within the Microsoft ecosystem. Listed here are a couple of examples:
Menace intelligence firm, Cluster25, recently reported that APT28 (a.okay.a. Fancy Bear), a Russian GRU (Predominant Intelligence Directorate of the Russian Common Employees) risk group, used a brand new technique to deploy the Graphite malware as lately as September 9.
The risk actor lures targets with a PowerPoint (.PPT) file allegedly linked to the Group for Financial Co-operation and Improvement (OECD), an intergovernmental entity working towards stimulating worldwide financial progress and commerce. Contained in the PPT file are two slides that includes directions in English and French for utilizing the Interpretation possibility within the Zoom video-conferencing app.
When the sufferer opens the doc in presentation mode and hovers the mouse over the hyperlink, a malicious PowerShell script is launched, downloading a JPEG file from a Microsoft OneDrive account. The doc additionally features a hyperlink that triggers the execution of a malicious PowerShell script by way of the SyncAppvPublishingServer instrument. Consequently, the malware is ready to use Microsoft Graph API and OneDrive on the sufferer’s pc for additional command-and-control communications.
On prime of that, weak Microsoft SQL servers are additionally being focused in a brand new wave of assaults with FARGO ransomware. MS-SQL servers are database administration programs, holding information for web companies and apps, which attackers primarily goal as a result of disrupting them could cause extreme enterprise bother. FARGO is likely one of the most distinguished ransomware strains specializing in MS-SQL servers, together with GlobeImposter.
The FARGO ransomware pressure excludes specific software program and folders from encryption to forestall the contaminated system from turning into utterly ineffective. Victims are additionally blackmailed with the specter of publishing the stolen materials publicly if victims didn’t pay the ransom.
It was later found that the vulnerabilities have been on account of using weak credentials and lack of up to date safety patching on the a part of the sufferer servers, which echoes the sooner points with Microsoft being troublesome to configure.
Microsoft’s Home windows working system isn’t far behind in bottleneck points. Based on research by Lansweeper, solely 2.6% of customers have upgraded to Home windows 11 one yr after its preliminary public launch. And 42% of PCs aren’t even eligible for automated improve on account of stringent system necessities from Microsoft. Which leaves enterprise IT managers struggling to improve or substitute tens of millions of machines earlier than 2025, which is when Microsoft has stated it can cease supporting Home windows 10.
How CISOs and safety leaders can mitigate dangers
Based on Steve Benton, VP of risk analysis at Anomali, the exploitation of vulnerabilities as they change into identified is only a means to an finish, part of an assault chain with a number of parts that should be profitable.
“The cruel fact is we must always all embrace the concept you shouldn’t depend on any product to be 100% safe,” Benton advised VentureBeat. “One should develop and execute a method that places an overlapping and multilayered suite of safety controls in place. [The strategy should be] targeted towards the broader assault chains made up of TTP [tactics, techniques and procedures] pushed by an attacker with motivation and objectives you will have understood by way of related, actionable intelligence.”
Benton recommends that the strategy, due to this fact, must be threefold:
- Make sure you perceive your assault floor and important property and have deployed an overlapping and multilayered set of safety controls. Additionally, be certain that these parts are totally deployed to the scope, totally operational and being monitored.
- Guarantee you will have outlined insurance policies and requirements for all of those parts such that they don’t expose exploitable points ( i.e., don’t give your self away cheaply to an attacker).
- Analyze what sorts of actors are prone to assault you. Take into consideration their motivation or finish objective, and the way they may go about it. This vital intelligence lets you prioritize your assets to guard your online business and your clients, and to determine and keep a dynamic safety posture in opposition to the present and rising threats related to you.
“Having an aggressive vulnerability and patch administration technique is crucial factor a company can do to maintain protected,” stated Mike Dausin, director of safety analysis and risk intelligence at Alert Logic. “On the similar time, it’s important to hearken to the alerts your gadgets produce; many profitable assaults go unnoticed just because logs and alerts from the affected gadgets go unnoticed. Gathering, processing and monitoring these alerts is vital to catch trendy threats.”
What the longer term holds for Microsoft
Jerrod Piker, aggressive intelligence analyst at Deep Instinct, stated that as Microsoft software program options proceed to get pleasure from widespread international use throughout enterprises of all sizes, we’ll seemingly see new vulnerabilities found at an much more speedy tempo than up thus far.
“If the latest vulnerabilities are any indication, these exploits will proceed to develop in complexity and scale,” stated Piker.
Piker stated that whereas Microsoft affords an in depth suite of safety options, there doesn’t seem to have been important strides made in securing the software program improvement life cycle itself.
“Microsoft has seemingly all the time been extra reactive with safety efforts, as an alternative of efficiently constructing safety into the software program improvement course of. This wants to vary. Till an entire shift is made to tighten safety throughout the improvement part, likelihood is we won’t see a marked enchancment within the variety of vulnerabilities found in Microsoft software program options,” he stated.
Likewise, Grotto believes that the safety guarantees might solely be totally achieved if primary safety features change into commonplace for all pricing tiers of Microsoft’s cloud companies.
“Fundamental safety features comparable to occasion logging and implementing multifactor authentication are a couple of IT options that ought to be thought of commonplace. Sadly, such ground-level options nonetheless appear to be lacking from Microsoft’s cloud ecosystem,” he stated. “This can be a main downside for cloud-based ecosystems reaching their full potential, from a safety standpoint.”
