The consumer tech giant, Microsoft, is not new when it comes to security flaws, especially following a recent Windows update. And this time, another vulnerability has been discovered which involves the latest update for version 1903 of the company’s flagship operating system.

Cybersecurity researchers from Windows Latest discovered a new issue affecting Windows 10 May 2019 Update (version 1903) on Build 18362.207 (KB4501375). A bug in Windows 10 May 2019 Update’s latest build breaks down the Remote Access Connection Manager service and affects the operation of VPN services.

Microsoft also confirmed that the new issue exists and it is currently patching up the problem that has affected tens of millions of its users.

“RASMAN service may stop working and result in the error “0xc0000005” The Remote Access Connection Manager (RASMAN) service may stop working, and you may receive the error “0xc0000005” on devices where the diagnostic data level is manually configured to the non-default setting of 0. You may also receive an error in the Application section of Windows Logs in Event Viewer with Event ID 1000 referencing “svchost.exe_RasMan” and “rasman.dll,” wrote Microsoft in their announcement.

How to fix the problem?

According to Microsoft, a workaround does exist, and affected users are required to manually configure the default telemetry settings by modifying Group Policies or Windows Registry.

To fix RASMAN error 0xc0000005 with Group Policies, follow these steps:

  • Launch Group Policies (gpedit.msc) from Start or Windows Run.
  • Browse to the following path:
  • Computer Configuration\Administrative Templates\Windows Components\Data Collection and Preview Builds\Allow Telemetry
  • Double-click on the policy to enable it.
  • Choose one of the three levels – Basic, Enhanced, and Full.
  • Open Start menu and search ‘Services’
  • On the Services tab, look for Remote Access Connection Manager.
  • Right-click on RASMAN and restart it.

You can also fix RASMAN error 0xc0000005 with Windows Registry:

  • Launch Windows Registry.
  • Browse to the following location: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection
  • Look for entry ‘AllowTelemetry’.
  • Double-click it and enter value 1, 2, or 3 (Basic, Enhanced, Full respectively).

In case the AllowTelemetry does not exist, you can create it manually. To create the entry, right-click the right-pane blank area and create DWORD (32-bit) named ‘AllowTelemetry.’

After applying the changes to Registry, you may need to restart RASMAN from Windows Services settings.

Version 1903 also broke Microsoft’s Sandbox feature

This RASMAN issue isn’t the only major flaw in Windows update in the recent months. Last month, Microsoft announced that there had been a significant vulnerability in the company’s Sandbox feature offering.

The tech giant admitted in an information release that Sandbox feature failed to launch after some users completed a system update. They wrote: “Windows Sandbox may fail to start with “ERROR_FILE_NOT_FOUND (0x80070002)” on devices in which the operating system language is changed during the update process when installing Windows 10, version 1903.”

On May 2019, Windows rolled out the Sandbox feature to premium clients and those who signed up for their beta testing program. The feature is designed to run an application on an isolated environment that is independent of a users installation server. To simply put it, Sandbox allows a computer to run a program or an app in a safe environment that is not connected to the network to prevent malicious programs especially those with malware and other forms of online threats from infecting the central installation.

In a bubble, the Sandbox feature is technically a virtual machine that mirrors an actual computer created on demand using Microsoft’s hypervisor using the same OS image as the one on your device. One key feature of the Sandbox virtual machine is that it is lightweight and only takes up a little more than 100MB, which has been optimized to boot and run faster, its focus is on security, and it works more efficiently using integrated kernel scheduler, virtual graphics, and smart memory management.

Facebook May Be Tracking Your Online Photos Too

While no active hacking is happening, security experts believe that the discovery carries heavy implications.

Published

It appears that Facebook is not only tracking people’s porn-watching behavior online but also the photos they download. A researcher has found Facebook trackers in several images that he downloaded that could potentially point out to one thing: Facebook is tracking everyone.

But this shouldn’t surprise anyone. Facebook isn’t necessarily the supreme authority in data safety and cybersecurity. But the discovery made by Edin Jusupovic proves that Facebook’s tracking mission does not end in its platform.

On Twitter, Jusupovic said that Facebook has embedded “hidden tracking codes” in photos that people download. He noticed a structural abnormality when looking at a hex dump of an image file from an unknown origin only to discover it contained a special IPTC instruction.

IPTC (International Press Telecommunications Council) is an organization that sets publishing standards, including image metadata.

According to the researcher, what he found, where facebook secretly embeds tracking codes in photos only, was ““shocking level of tracking,” adding that “the take from this is that they can potentially track photos outside of their own platform with a disturbing level of precision about who originally uploaded the photo (and probably so much more).”

Yesterday, Z6Mag published a report that a group of researchers has found hidden tracking codes in different porn sites online that can be traced back to Facebook, Google, and Oracle. Researchers from Microsoft, Carnegie Mellon, and the University of Pennsylvania scanned 22,484 porn sites and found that 93% of the sade porn sites include hidden codes from the three tech giants.

“Our analysis of 22,484 pornography websites indicated that 93% leak user data to a third party. Tracking on these sites are highly concentrated by a handful of major companies, which we identify. We successfully extracted privacy policies for 3,856 sites, 17% of the total. The policies were written such that one might need a two-year college education to understand them. Our content analysis of the sample’s domains indicated 44.97% of them expose or suggest a specific gender/sexual identity or interest likely to be linked to the user,” the study’s abstract stated.

Jusopovic’s finding “IPTC special instructions” simply refers to a special kind of coded watermark that Facebook adds to tag the image in its own coding. These are where the “tracking” comes into the picture – those tags can be read later. Meaning, Facebook will now how the data of people who had downloaded the image, reuploaded it, and all other information that can be linked to the movement of the image across the internet.

What does it imply?

Adding coded watermarks to images is not new tho. It can be used by the company in arbitrating copyrights claims, or providing better user service, and even in targeting the right target market for advertising. However, as Jusopovic states, what he found was a “shocking level of tracking.”

According to one analyst, the metadata has been added since 2016 and “contains an IPTC block with an ‘Original Transmission Reference’ field that contains some kind of text-encoded sequence. This coding method lets Facebook “know it has seen the image before when it gets uploaded again,” explained a user on Reddit. “It is yet another way to learn associations between people. Person 1 uploaded a bunch of the same photos Person 2 uploaded, let’s show them both all the same advertisements!”

But it needs to be clarified that there is no active tracking that it is happening. With “tracking,” Jusopovic means that Facebook and other people with the right tools can access all the metadata in a photo including the crumbles it picks up as it moves from one platform to another. However, this too carries a lot of security of implications.

“Hidden data can be predictably transmitted through social network images with high-fidelity – and AI can hide that data in plain sight, at large-scale, and beyond human visual discernment, making steganalysis and other countermeasures difficult,” Zack Allen from ZeroFOX.

Nonetheless, the discovery of Jusopovic is proof that Facebook is yet to make do with its promises to protect people’s data as well as make sure that people are aware of what happens to their data. This promise follows the high-profile case involving Facebook and Cambridge Analytica, where the social media giant was slapped with a five-billion fine by the FTC.

Educational Institutions And Services Are Targets Of Recent Data Breaches

Two separate data breach have affected 62 US colleges and more than 7 million users of the K12.com, with vulnerabilites already exploited by hackers.

Education institutions have been victims of two separate data breaches and hacker attacks that have exposed millions of student data to the prying eyes in the wild.

For one of the exposure, more than 62 US colleges have been breached by a hacker that has exploited a vulnerability in an enterprise resource planning (ERP) web app; the U.S. Education Department confirmed this week.

Ellucian Banner Web Tailor, a module of the Ellucian Banner ERP, which allows universities to customize and design their hope-page websites and online applications, has had a vulnerability that was exploited by a hacker who made fake user profiles that are “almost immediately for criminal activity.”

Banner Web Tailor is a web tool, made for higher education institutions, that provides registration, curriculum management, advising, administration, and reporting functionality. Students can access and change their registration, graduation, and financial aid information. It is also used by professors and teachers to input grades which the students can then view online. It is used by hundreds of institutions, many of which have opted to use the Single Sign-on Manager to participate in CAS- and SAML-based single sign-on services.

Joshua Mulliken, a cybersecurity researcher discovered a vulnerability in the authentication mechanism used by the two modules earlier this year. This vulnerability allowed a hacker to hijack students’ web-sessions and take over their accounts. Ellucian fixed the vulnerability in May, and public disclosure was published, by both the researcher and NIST.

“An improper authentication vulnerability (CWE-287) was identified in Banner Web Tailor and Banner Enterprise Identity Services. This vulnerability is produced when SSO Manager is used as the authentication mechanism for Web Tailor, where this could lead to information disclosure and loss of data integrity for the impacted user(s). The vendor has verified the vulnerability and produced a patch that is now available. For more information, see the postings on Ellucian Communities,” reads the public disclosure of the vulnerability.

According to the announcement made by the US Education Department, hackers have already started exploiting the said vulnerability. “The Department has identified 62 colleges or universities that have been affected by the exploitation of this vulnerability,” officials said.

We have also recently received information that indicates criminal elements have been actively scanning the internet looking for institutions to victimize through this vulnerability and developing lists of institutions for targeting with this exploitation.”

The attackers, as said by the officials for the Education Department, “leverage scripts in the admissions or enrollment section of the affected Banner system to create multiple student accounts.” One victim reported that the attackers created thousands of fake accounts over days, with around 600 accounts created within 24 hours.

K12.com exposes users’ data

Meanwhile, a recent data breach involving K12.com has compromised more than seven million students’ data who use one of the company’s programs, leaving the data accessible to anyone online.

In June 25, 2019, Comparitech and security researcher Bob Diachenko uncovered the exposure when they found an unprotected MongoDB out in the open as they scan for unsecured databases.

The exposure affected K12.com’s A+nyWhere Learning System (A+LS), which is used by more than 1,100 school districts. The database has 6,988,504 records containing students’ data. The information held within each file included:

  • Primary personal email address
  • Full name
  • Gender
  • Age
  • Birthdate
  • School name
  • Authentication keys for accessing ALS accounts and presentations
  • Other internal data

“In this instance, an old version of MongoDB (2.6.4) was being utilized. This version of the database hasn’t been supported since October 2016. What’s more, the Remote Desktop Protocol (RDP) was enabled but not secured. As a result, the database was indexed by both the Shodan and BinaryEdge search engines. This means the records contained in the database were visible to the public,” said the researchers.

The researchers were able to reach out to K12.com, and a representative from the company said: “K12 takes data security very seriously. Whenever we are advised of a potential security issue, we investigate the problem immediately and take the appropriate actions to remedy the situation.”

While the danger that comes from the exposed data was not as huge as the first data breach involving the world’s educational system, the researchers said that it carries with it some implications.

“While the leak of this information isn’t as bad as, for example, the exposure of financial data or Social Security numbers, it does have its implications. These pieces of information can be used to target individual students in spear phishing and account takeover fraud. Having their school name made public could potentially put students at risk of physical harm,” they said.

Morpheus Chip Is Almost Impossible To Hack Says Researchers

Much like the Greek god, Morpheus chip is a hacker’s nightmare.

As cyber criminals up their game in terms of deriving different sophisticated techniques to compromise systems, steal funds, and take over identities, a group of researchers has developed what some media outlets called unhackable chip that is designed to confuse hackers and prevent them from infiltrating systems at the microprocessor level.

Researchers from the University of Michigan call it “Morpheus,” and it said to be “vulnerability tolerant” as it blocks potential attacks by confusing hackers and making it difficult for them to hack at the chip level.

Morpheus is backed by the famous US Defense Advanced Research Projects Agency (DARPA) and is a new chip architecture that bridges the gap between program and machine-level semantics making a system’s firewall impenetrable.

“Attacks often succeed by abusing the gap between program and machine-level semantics– for example, by locating a sensitive pointer, exploiting a bug to overwrite this sensitive data, and hijacking the victim program’s execution,” reads the study’s abstract.

Most common attacks today use malware to trick systems into misusing basic programming possibilities such as permissions and code injection, or into manipulating unusual states.

“In this work, we take secure system design on the offensive by continuously obfuscating information that attackers need, but normal programs do not use, such as [the] representation of code and pointers or the exact location of code and data,” the researchers added.

Just like the Greek god, Morpheus can manipulate program values

According to the developers of the Morpheus, the new chip architecture combines two powerful protections: ensembles of moving target defenses and churn.

The first layer of protection which is ensembling moving target defenses, the chip architecture randomizes key program values (e.g., relocating pointers and encrypting code and pointers) “which forces attackers to probe the system before an attack extensively.”

This means that much like Morpheus, the Greek god of sleep, the chip architecture can make fundamental program values (dreams) to shapeshift to make it harder for future hackers to distinguish them and exploit their vulnerabilities.

The second layer of protection brought by the new chip architecture is the churn, which transparently re-randomizes program values running underneath the system. “With frequent churn, systems quickly become impractically difficult to penetrate,” they said.

Furthermore, Morpheus is also designed to perform both the protection processes, re-randomizing program values every 50 milliseconds, which is faster than any hacker can catch up with, making it highly difficult to locate.

“Each moving target defense in Morpheus uses hardware support to individually offer more randomness at a lower cost than previous techniques. When ensembled with churn, Morpheus defenses offer strong protection against control-flow attacks, with our security testing and performance studies revealing:

  • high-coverage protection for a broad array of control-flow attacks, including protections for advanced attacks and an attack disclosed after the design of Morpheus, and
  • negligible performance impacts (1%) with churn periods up to 50 ms, which our study estimates to be at least 5000x faster than the time necessary to possibly penetrate Morpheus,” they wrote in their study.

One of the proponents of the study explained how the Morpheus chip works using analogies he derived from solving the Rubik’s cube puzzle.

“Imagine trying to solve a Rubik’s Cube that rearranges itself every time you blink. That’s what hackers are up against with Morpheus. It makes the computer an unsolvable puzzle,” University of Michigan’s Todd Austin explains to journalists.

The researchers said that another way of understanding how Morpheus works is that it is a low-level version of a standard protection technique called Address Space Layout Randomisation (ASLR).

Nonetheless, the researchers said that Morpheus chip architecture is not “unhackable.” Other techniques could fight off its protective mechanisms as it does not address all forms of attack. However, the innovation will reduce the attack surface at the very least.

“Looking ahead, we see great potential for EMTD technologies,” the researchers said. “Beyond control-flow attacks, we envision that a similar approach could be adopted to protect against side-channel attacks, timing attacks, Rowhammer attacks, and even cache attacks. To address each of these additional challenges, we will explore what assets the attacker needs and then develop efficient mechanisms to boost uncertainty and stifle attacks,” they added.
