WizardOpium Exploit : Update Google Chrome ASAP!

The WizardOpium Exploit : What Is It?

Kaspersky’s automated Exploit Prevention subsystem detected the exploit, which they dubbed WizardOpium. It used a zero day vulnerability that had hitherto not known to developers.

The WizardOpium Exploit : How Does It Work?

The attacks, which Kaspersky called Operation OpiumWizard, began with an infiltration at a Korean news website, where attackers managed to inject malicious code.

It loads a script from a third-party site that first checks if the system is suitable for infection – they were interested only in Chrome for Windows, not older than version 65.

If the operating system and browser requirements are met, the script downloads the WizardOpium exploit piece by piece, reassembles and decrypts it.

The script then runs another check on the version of Google Chrome, working exclusively with Chrome 76 or 77.

After verifying that it has the right Chrome version, the script then leverages the use-after-free vulnerability CVE-2019-13720, based on the improper use of system memory.

By manipulating the system memory, the exploit gains permission to read and write data, which it immediately uses to download, decrypt and run the malware package.

The WizardOpium Exploit : Solution

Kaspersky cybersecurity products will detect the exploit, and identify it as Exploit.Win32.Generic.

On discovering it, they reported it to Google with the identifier CVE-2019-13720.

Google fixed the bug in Chrome 78.0.3904.87 for Windows, macOS and Linux. Just make sure you update to that version, or newer… ASAP!

To make sure you have the update, follow these steps :

Click on the 3 vertical dots at the upper right corner of Chrome (Customise and control Google Chrome)
Select Help > About Google Chrome.
In the About Chrome page, it should say that you have Version 78.0.3904.87 or higher
If not, Chrome will automatically start looking for, and installing the latest update
Click Relaunch to restart Chrome.

AMD RyzenFall, MasterKey, Fallout, Chimera Mitigation Guide

What’s Really Affected?

While it is accurate to say that the AMD Ryzen and AMD EPYC processors are affected by RyzenFall, MasterKey, Fallout and Chimera, these vulnerabilities do not affect the actual processor cores. Neither are they related to the Zen microarchitecture.

This makes them completely different from the Meltdown and Spectre vulnerabilities that have been “built into” over 2,800 CPU models!

Instead, the new RyzenFall, MasterKey, Fallout and Chimera security vulnerabilities are found in:

the AMD Secure Processor (integrated into the new Ryzen and EPYC processors), and
the AMD Promontory chipsets that are paired with Ryzen and Ryzen Pro desktop processors.

The AMD Promontory chipset is used in many Socket AM4 desktop, and Socket TR4 high-end desktop (HEDT) platforms.

AMD EPYC, Ryzen Embedded, and Ryzen Mobile platforms do not use the Promontory chipset.

The AMD RyzenFall, MasterKey, Fallout + Chimera Mitigations

RyzenFall + Fallout

Issue : An attacker with administrative access can write to the AMD Secure Processor (PSP registers to exploit vulnerabilities in the interface between the x86 processor core and AMD Secure Processor.

Impact : The attacker can circumvent security controls to install difficult-to-detect malware in the x86 System Management Mode (SMM). The access is not persistent across reboots.

Planned Mitigations : AMD will issue AMD Secure Processor firmware patches through BIOS updates in coming weeks. No performance impact is expected.

MasterKey (PSP Privilege Escalation)

Issue : An attacker with administrative access can write malicious firmware updates, without the AMD Secure Processor (PSP) detecting the “corruption”.

Impact : The attacker can circumvent security controls to install difficult-to-detect malware. These changes are persistent, even following a system reboot.

Planned Mitigations : AMD will issue AMD Secure Processor firmware patches through BIOS updates in coming weeks. No performance impact is expected.

Chimera

Issue : An attacker with administrative access can install a malicious driver to access certain features in the AMD Promontory chipset.

Impact : The attacker can access physical memory through the Promontory chipset. The attacker can also install difficult-to-detect malware in the chipset, but this is not persistent across reboots.

Planned Mitigations : AMD will issue chipset patches through BIOS updates in coming weeks. No performance impact is expected.

Complete List Of CPUs Vulnerable To Meltdown / Spectre Rev. 8.0

11 Replies

The speculative execution CPU bug that literally kneecapped Intel, also affects many AMD and ARM processors. This means BILLIONS of CPUs around the world, including those powering smartphones, are affected by Meltdown and/or Spectre.

Our article Everything On The Meltdown + Spectre CPU Flaws! summarises the key details of the speculative execution bug, and what we can do about it. This guide is to help those who want a full list of affected CPUs. Because we intend this to be an exhaustive list, we split it into multiple sections.

What Are Meltdown And Spectre?

Meltdown and Spectre are two exploits that take advantage of three variants of the speculative execution bug that affects billions of CPUs around the world.

The Spectre exploit targeted Variants 1 and 2, while the Meltdown exploit targets Variant 3, of the CPU bug.

For more information on the speculative execution bug, and the Meltdown / Spectre exploits, please read Everything On The Meltdown + Spectre CPU Flaws!

The CPUs Vulnerable To Meltdown / Spectre Updated!

For easy reference, we divided the affected CPUs by Company (arranged ALPHABETICALLY – no conspiracy, we promise), and subsequently by Segment (Workstation / Desktop / Mobile), or affected variants.

As of Revision 8.0, we believe we have covered all of the affected AMD, Apple, ARM, IBM, Intel and VIA CPUs. But we will add more CPUs (and devices) as and when they’re noted to be vulnerable to the Meltdown and Spectre exploits.

Note : It’s arguable that all CPUs that uses speculative execution to any degree are potentially vulnerable to Meltdown or Spectre or a future exploit. We will only focus on CPUs that are confirmed to be vulnerable to Meltdown or Spectre.

Vulnerable CPUs By The Numbers Updated!

Here is a quick summary of the number of CPUs vulnerable to Meltdown or Spectre, according to the company, and the type of processor.

Company	Spectre 1	Spectre 2	Meltdown
AMD	295 Server CPUs 42 Workstation CPUs 396 Desktop CPUs 208 Mobile CPUs	295 Server CPUs 42 Workstation CPUs 396 Desktop CPUs 208 Mobile CPUs	None

Everything On The Meltdown + Spectre CPU Flaws! Rev. 3.0

14 Replies

The Meltdown and Spectre CPU flaws that the Google Project Zero team discovered are arguably the worst we have ever known. These vulnerabilities were built into BILLIONS of CPUs that we have been using for the last decade or so.

Not just Intel CPUs, but also CPUs made by AMD, Apple and ARM. Even those that power our smartphones and other smart devices!

Let’s take a look at what we know so far about Meltdown and Spectre, how they affect you, and what we can do about them.

This story is still developing. We will update the article as and when new details emerge. Be sure to check back and refresh the page for the latest information!

The Meltdown + Spectre Vulnerabilities

The Project Zero team identified these vulnerabilities in 2017, reporting it to Intel, AMD and ARM on 1 June 2017.
These vulnerabilities take advantage of the Speculative Execution and Branch Prediction features of the modern processor, that have been used for many years to improve performance.
Speculative Execution lets the CPU predict and pre-execute the next instruction, allowing it to “instantly” deliver the results if it’s correct.
Branch Prediction helps the CPU predict future execution paths that should be speculatively-executed for better performance.
There are THREE (3) variants of the speculative execution CPU bug :
- Variant 1 : Bounds Check Bypass (CVE-2017-5753)
- Variant 2 : Branch Target Injection (CVE-2017-5715)
- Variant 3 : Rogue Data Cache Load (CVE-2017-5754)
The Spectre attack (whitepaper) exploits variants 1 and 2.
The Meltdown attack (whitepaper) exploits variant 3.
There is a Variant 3a, which appears to affect only certain ARM processors.

What’s The Difference Between Meltdown & Spectre?

Spectre tricks the CPU branch predictor into mis-predicting the wrong path, thereby speculatively executing code that would not otherwise be executed.
Meltdown takes advantage of the out-of-order execution capability of modern processors, tricking them into executing malicious code that would normally not be allowed.
The Spectre name is based on both the root cause – speculative execution, and the fact that it is not easy to fix, and will haunt us for a long time like a spectre (ghost).
The Meltdown name was chosen because the vulnerability “basically melts security boundaries which are normally enforced by the hardware“.

How Bad Are Meltdown & Spectre?

The Spectre exploits let an attacker access and copy information from the memory space used by other applications.
The Meltdown exploit lets an attacker copy the entire physical memory of the computer.
Unless patched, the affected processors are vulnerable to malware and cyberattacks that exploits this CPU bug to steal critical information from running apps (like login and credit card information, emails, photos, documents, etc.)
While the Meltdown exploit can be “fixed”, it is likely that the Spectre exploit cannot be fixed, only mitigated, without a redesign of the processors. That means we will have to live with the risks of a Spectre attack for many more years to come.

How Many Processors Are Affected? Updated!

Intel Detection Tool?

The Intel-SA-00086 Detection Tool does NOT detect the processor’s susceptibility to these vulnerabilities. It only checks for different vulnerabilities affecting the Intel Management Engine.

InSpectre

Our reader Arthur shared that the Gibson Research Corporation has an aptly-named utility called InSpectre.

It checks for Meltdown and Spectre hardware and software vulnerabilities in a Windows system. It will help you check if your system is getting patched properly against these vulnerabilities.

What Is Being Done??? Updated!

Note : The terms “mitigate” and “mitigation” mean the possibility of a successfully attacked are reduced, not eliminated.

Intel has started issuing software and firmware updates for the processors introduced in the last 5 years. By the middle of January 2018, Intel expects to have issued updates for more than 90% of those CPUs. However, that does not address the other Intel processors sold between 2010 and 2012.
Microsoft and Linux have started to roll our the KPTI (Kernel Page Table Isolation) patch, also known as the KAISER (Kernel Address Isolation to have Side-channels Efficiently Removed) patch.
The KPTI or KAISER patch, however, will only protect against the Meltdown exploit. It has no effect on a Spectre attack.
Microsoft Edge and Internet Explorer 11 received the KB4056890 security update on 3 January 2018, to prevent a Meltdown attack.
Firefox 57 includes changes to mitigate against both attacks.
Google Chrome 64 will be released on 23 January 2018, with mitigations against Meltdown and Spectre attacks.
For Mac systems, Apple introduced mitigations against Spectre in macOS 10.13.2 (released on 8 January 2018), with more fixes coming in macOS 10.13.3.
For iOS devices, Apple introduced mitigations against Meltdown in iOS 11.2 and tvOS 11.2.
On 8 January 2018, Apple released iOS 11.2.2, which mitigates the risk of the two Spectre exploits in Safari and WebKit, for iPhone 5s, iPad Air, and iPod touch 6th generation or later.
ARM has made available the KPTI / KAISER kernel patches for Linux, while Google will provide them for Android.
Google patched Android against both exploits with the December 2017 and January 2018 patches.
Google shared details of their Return Rrampoline (Retpoline) binary modification technique that can be used to protect against Spectre attacks. It is a software construct that ensures that any associated speculative execution will “bounce” (as if on a trampoline) endlessly.
NVIDIA issued six driver and security updates for affected devices and software between 3-9 January 2018.
On 11 January 2018, AMD announced that the “majority of AMD systems” have received the mitigation patches against Spectre 1, albeit some older AMD systems got bricked by bad patches. They also announced that they will make “optional” microcode updates available for Ryzen and EPYC processors by the same week.
In the same 11 January 2018 disclosure, AMD also shared that Linux vendors have started to roll out OS patches for both Spectre exploits, and they’re working on the “return trampoline (Retpoline)” software mitigations as well.[adrotate group=”2″]
On 23 January 2018, Apple released Meltdown patches for macOS Sierra and OS X El Capitan, but not macOS High Sierra.
On 23 January 2018, Microsoft finally revealed their Spectre and Meltdown patch schedule.
On 24 January 2018, AMD revealed their 11 software mitigations for both Spectre exploits.
The 24 January 2018 AMD whitepaper also revealed that the AMD K10 and K8 processors are vulnerable as well, adding an additional 663 CPU models to the list of vulnerable processors.
On 2 February 2018, Microsoft released KB4078130 to disable the Spectre 2 patches that were causing many Intel systems to randomly and spontaneously reboot.
On 8 February 2018, an Intel microcode update schedule revealed that their Penryn-based processors are also vulnerable, adding an additional 314 CPU models to the list of vulnerable processors.
On 14 February 2018, Intel revealed an expanded Bug Bounty Program, offering up to $250,000 in bounty awards.

Some AMD PCs Got Bricked

In the rush to mitigate against Meltdown and Spectre, Microsoft released Windows 10 patches that bricked some AMD PCs. They blamed the incorrect / incomplete documentation provided by AMD.

You can read more about this issue @ These Windows 10 Updates Are Bricking AMD PCs!

Buggy Intel Spectre 2 Patches Updated!

Intel’s rush to patch Meltdown and Spectre resulted in buggy microcode patches, causing several generations of their CPUs to randomly and spontaneously reboot.

So far, over 800 Intel CPU models have been identified to be affected by these spontaneous reboot issues. If you have one of the affected CPUs, please hold off BIOS / firmware updates!

Intel has identified the cause as the Spectre 2 patches in their microcode updates for some of these processors. They’re still investigating the cause of the other affected CPU models.

Fortunately for Windows users, Microsoft issued the KB4078130 emergency update to stop the reboots while Intel worked to fix the issue.

You can read more about this issue @ The Intel Spectre Reboot Issue, and the Microsoft solution @ KB4078130 : Emergency Windows Update To Disable Intel Spectre Patches!

What Should You Do? Updated!

First and foremost – DO NOT PANIC. There is no known threat or attack using these exploits.

Although we listed a number of important patches below, the buggy updates are worse than the potential threat they try to fix. So we advise HOLDING OFF these patches, and wait for properly-tested versions a few weeks down the line.

If you are using Windows, make sure you install the latest Microsoft Spectre and Meltdown updates.
If you are using a Mac system, get the latest Apple Spectre and Meltdown patches.
If you are using an iOS device, get updated to iOS 11.2 or tvOS 11.2.
If you are using Firefox, update to the latest Firefox 57.
If you are using Google Chrome, make sure you watch out for Chrome 64, which will be released on 23 January.
Download and install the latest software firmware updates from your PC, laptop, motherboard brands. In particular, install the latest driver for the Intel Management Engine (Intel ME), the Intel Trusted Execution Engine (Intel TXE), and the Intel Server Platform Services (SPS)
If you are running an ARM processor on Linux, grab the kernel patches.
IBM POWER system users can download and install these firmware updates.
Users of affected NVIDIA systems can download and install these driver and firmware updates.
If you are using an Intel system, hold off updating your firmware, unless you have already verified that your CPU is not affected by the buggy Intel patches, or Intel has already issued corrected patches.

The Performance Impact Of The Mitigation Patches

Many benchmarks have been released, showing performance impacts of between 5% to 30%, depending on the type of benchmark and workload. Microsoft has called those benchmark results into question, stating that they did not cover both operating system and silicon microcode patches.

They released an initial report on their findings, which we have summarised in our article – Pre-2016 Intel CPUs Hit Worst By Meltdown + Spectre Fix.

Apple Rushed Out macOS Root Bug Fix & It Shows…

1 Reply

Lemi Orhan Ergin did not give Apple any forewarning when he publicly revealed the massive macOS root bug on Twitter. He basically exposed a zero-day vulnerability for hackers to use, while Apple rushed on a bug fix. The good news is Apple just issued the root bug fix in Security Update 2017-001.

This is really fast work, but it also showed their sloppiness. Hopefully, the bug fix does not introduce additional bugs!

macOS Security Update 2017-001

[adrotate group=”2″]

Apple released macOS Security Update 2017-001 just a day after the macOS root bug was revealed. They also gave us more information on the bug that caused so much ruckus around the world (and rightly so).

The bug only affected macOS High Sierra 10.13.1.
The bug did not affect computers running macOS Sierra 10.12.6 or earlier.
They confirmed that it allowed an attacker to “bypass administrator authentication without supplying the administrator’s password“.

You can get more details on the root bug in our dedicated article – The macOS High Sierra Root Bug Explained!

How Do I Download The Root Bug Fix?

The macOS root bug fix is now available for download via the App Store. If it doesn’t appear yet, just click on the Updates icon to refresh.

Please note that this bug fix will reset and disable the root user account. If you need to use the root user account, you will need to re-enable it, and change its password, after applying the update.

Terminal Users, Watch Out!

If you’re using Terminal to update though, you may face some complications due to Apple’s sloppiness. Chai discovered that Apple accidentally used a space instead of the version number.

This is not an issue if you are downloading the patch through the App Store. But if you’re applying the patch via Terminal, you need to add a space.

The macOS High Sierra Root Bug Explained! Rev. 2.0

3 Replies

The Internet is abuzz with the shocking revelation that now everyone can hack an Apple computer… as long as it’s using the latest macOS High Sierra operating system. Let us explain what’s going on, and share with you the workaround for the macOS High Sierra root bug.

Updated @ 2017-11-30 : Added a new section on the Apple bug fix (Security Update 2017-001) [1], and additional information on the root bug [2].

What Is Root User?

If you are the primary user of a MacOS X system, you have an administrator account with administrator privileges. This gives you more privileges and access than a standard user account. However, that is not the highest access level possible.

There is a Mac superuser account called “root” that gives you elevated read and write privileges to hidden or protected areas of the system. With the Mac root user account, you can even access files in other user accounts.

In fact, it gives you such God-like powers, you can modify or even delete critical system files. In fact, a Mac root user can use the rm -rf * command to delete the contents of every mounted drive in the computer, until macOS crashes when a crucial file or folder is deleted.

So this Mac root user account should only remain disabled unless you really, REALLY need to use it.

The macOS High Sierra Root Bug Updated!

On Tuesday, 28 November 2017, Turkish software developer Lemi Orhan Ergin revealed the macOS High Sierra root bug. With a few simple steps, anyone can gain elevated root user privileges in any computer running macOS High Sierra! Here is a summary of what we know about the root bug :

The root bug exploit requires a computer running macOS High Sierra, with multiple user accounts.
When prompted for a username and password, use these steps to gain root user access without any password :
- Type “root” as the username and leave the password field blank.
- Just click “Unlock” twice.
The root bug cannot be exploited remotely, unless screen sharing is enabled.
The root bug was introduced in macOS High Sierra 10.13.1. Earlier versions of macOS were not affected.
Apple confirmed that the bug was due to “a logic error… in the validation of credentials“.
Apple also confirmed that the bug would allow an attacker to “bypass administrator authentication without supplying the administrator’s password“.
Several security researchers successfully replicated the bug.

How Serious Is This Root Bug?

The macOS High Sierra root bug is EXTREMELY serious, because it allows a hacker to easily bypass all of the macOS operating system’s security protections.

It doesn’t matter if you encrypted your computer, and secured it with an extremely long and complex password. Anyone who gains root user privileges using this bug can access (read, copy or move) the files in any user account (even those of an administrator) without knowing the password.

What’s even more troubling is that the root bug works even with a disabled root user account. This means the vast majority of Apple computers running on High Sierra are compromised, as the root user account is disabled by default.

How To Fix The Root Bug?

Unlike other security researchers, Lemi Orhan Ergin did not forewarn Apple before publicly revealing the bug, on Twitter no less. He basically exposed a zero-day vulnerability for hackers to use, while Apple rushes to fix the bug.

1. Install macOS Security Update 2017-001 New!

Apple just released Security Update 2017-001. This update will remove the root bug and improve credential validation. INSTALL THIS UPDATE NOW!

Note : This bug fix will reset and disable the root user account. If you need to use the root user account, you will need to re-enable it, and change its password, after applying the update.

Note : Apple rushed out this update so quickly that they accidentally used a space instead of the version number. You can read more about this in our article – Apple Rushed Out macOS Root Bug Fix & It Shows…

This is not an issue if you are downloading the patch through the App Store. But if you’re applying the patch via Terminal, you need to add a space.

softwareupdate -i “Security Update 2017-001- “

2. Enable Root User With Your Own Password

[adrotate group=”2″]

If you cannot apply Apple’s bug fix yet, you can block this root bug by enabling the root user account, and setting a password for it.

It’s not so straightforward, so we created a step-by-step guide for you – The Mac Root User Login & Password Guide.

3. Use Additional Encryption

Alternatively, you can opt to move your sensitive data to encrypted containers or drives using third-party encryption utilities like VeraCrypt. Hackers may use the High Sierra root bug to gain access to the encrypted containers or drives, but without the correct password, the actual data won’t be accessible.

4. Physically Protect Your Apple Computer

The good news is the High Sierra root bug generally requires physical access to your Apple computer. Until this bug is fixed, you should make sure your Apple computer is never left unsupervised.

Keep it in a locked room or bag, whenever you are not using it. If no one can get to it, they cannot use the bug to gain root access.

5. Disable Screen Sharing

The High Sierra root bug can be exploited remotely if Screen Sharing is enabled. So make sure you disable Screen Sharing.

The Mac Root User Login & Password Guide

1 Reply

Want to have elevated God-like privileges to your Mac OS X system? Then you need to be a Mac root user. In this guide, we will teach you how to enable the root user account in OS X, change the password, and disable it.

For experienced users or power users, you can use Terminal to quickly make these changes :

[adrotate group=”2″]

If you are an inexperienced user, you can use the GUI method, which has more steps but does not require keying in commands.

What Is The Mac Root User?

If you are the primary user of a MacOS X system, you have an administrator account with administrator privileges. This gives you more privileges and access than a standard user account. However, that is not the highest access level possible.

In fact, it gives you such God-like powers, you can modify or even delete critical system files. So this Mac root account should only remain disabled unless you really, REALLY need to use it.

OS X High Sierra currently has a root bug that allows practically root access in a few simple steps. Therefore, Apple advises you to enable the Mac root account, with your own password, until they fix the bug.

How To Enable The Mac Root User / Change Password (Terminal Method)

Requisite : You need to be logged into an administrator account.

Please note this method is used to both enable the root account, and to change its password. The single command line of sudo passwd root both changes its password, while enabling the root account.

Step 1 : Click on the Apple () menu, and select System Preferences.

Step 2 : Click on Utilities, and select Terminal.

Step 3 : Type sudo passwd root and press Enter.

sudo passwd root

Step 4 : You will be asked for your administrator password, not the new root password. Key in your administrator password and hit Enter.

Step 5 : Now key in the new root password, and hit Enter. Then retype the new root password for verification, and hit Enter.

That’s it! You have successfully enabled the Mac root account, with a password of your choice. To use it, you need to log off your administrator account.

How To Disable The Mac Root User (Terminal Method)

Requisite : You need to be logged into an administrator account.

Step 1 : In Terminal, type dsenableroot -d and press Enter.

dsenableroot -d

Step 2 : Key in your administrator password (not the root user password), and hit Enter.

If you succeed, you will see the notification : ***Successfully disabled root user.

Clock Share Bug In iOS Allows Access To Data

How To Exploit This Bug In iOS

Here is how you can exploit the bug in iOS 9.2.1 to gain access to every photo, video and contact stored in the iOS device, whether it is an iPhone, an iPad or an iPod touch.

Log into the iOS device using the passcode / Touch ID.
Open the Clock app and go to World Clock, and add a new Clock.
Type a random word in the Search bar.
Select the random word and tap to Share as a Message.

Once the New Message screen opens, turn off the iOS device.
Call Siri (without logging in using Touch ID / passcode) and ask for the time
Click on the Clock after Siri tells you the time.
Siri will not open up the World Clock, but will take you straight into New Message.
Now add a random word to “To:” bar, and press Return.
Double tap on the random word (now green in colour). It will bring you to the Info screen.
Tap on Create New Contact.
Tap on Add Photo. This will allow you to access the Photos app and EVERY photo and video in the iOS device.
You can also tap on Add to Existing Contact to access the entire Contact List.

[adrotate banner=”5″]

Don’t Worry… Too Much

As you can tell by now, this security bug is very hard for a hacker to exploit. It requires prior access to the iOS device to “set up” the exploit.

The hacker will have to trick the owner into granting access to the iOS device. Then the hacker can follow the steps above up to no. 5. This will allow the hacker to exploit the bug (at a later time) to gain access to the iOS device’s photos, videos and contacts.

While this is a remote possibility, we nevertheless reported the security bug to Apple :

We then tested to see if the exploit would work on iOS 9.3 beta, and discovered something interesting.

It appears that Apple finally decided that it was superfluous to offer a Share option in the Clock app. How is that functionality useful to the user? It’s practically useless. So they removed the Share option completely.

In other words, even if you are logged into the iOS device, you can no longer go to the Clock app, key in a random word and Share it. The option is gone. As far as we can tell, it was gone as early as iOS 9.3 beta 5. We confirmed this in iOS 9.3 beta 6 as well (naturally).

So don’t worry too much. The coming iOS 9.3 update will fix this security bug in iOS 9.2.1 once and for all. In the meantime, just be careful who you lend your iOS device to!
