Flaws in Popular Self-Encrypting SSDs Let Attackers Decrypt Data

Flaws in Popular Self-Encrypting SSDs Let Attackers Decrypt Data
Nov 06, 2018
We all have something to hide, something to protect. But if you are also relying on self-encrypting drives for that, then you should read this news carefully. Security researchers have discovered multiple critical vulnerabilities in some of the popular self-encrypting solid state drives (SSD) that could allow an attacker to decrypt disk encryption and recover protected data without knowing the password for the disk. The researchers—Carlo Meijer and Bernard van Gastel—at Radboud University in the Netherlands reverse engineered the firmware several SSDs that offer hardware full-disk encryption to identify several issues and detailed their findings in a new paper ( PDF ) published Monday. "The analysis uncovers a pattern of critical issues across vendors. For multiple models, it is possible to bypass the encryption entirely, allowing for a complete recovery of the data without any knowledge of passwords or keys," the researchers say. The duo successfully tested their

New Cold Boot Attack Unlocks Disk Encryption On Nearly All Modern PCs

New Cold Boot Attack Unlocks Disk Encryption On Nearly All Modern PCs
Sep 13, 2018
Security researchers have revealed a new attack to steal passwords, encryption keys and other sensitive information stored on most modern computers, even those with full disk encryption. The attack is a new variation of a traditional Cold Boot Attack , which is around since 2008 and lets attackers steal information that briefly remains in the memory (RAM) after the computer is shut down. However, to make the cold boot attacks less effective, most modern computers come bundled with a safeguard, created by the Trusted Computing Group (TCG), that overwrites the contents of the RAM when the power on the device is restored, preventing the data from being read. Now, researchers from Finnish cyber-security firm F-Secure figured out a new way to disable this overwrite security measure by physically manipulating the computer's firmware, potentially allowing attackers to recover sensitive data stored on the computer after a cold reboot in a matter of few minutes. "Cold boot

How to Find and Fix Risky Sharing in Google Drive
Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ

Apple macOS Bug Reveals Cache of Sensitive Data from Encrypted Drives

Apple macOS Bug Reveals Cache of Sensitive Data from Encrypted Drives
Jun 18, 2018
Security researchers are warning of almost a decade old issue with one of the Apple's macOS feature which was designed for users' convenience but is potentially exposing the contents of files stored on password-protected encrypted drives. Earlier this month, security researcher Wojciech Regula from SecuRing published a blog post , about the "Quick Look" feature in macOS that helps users preview photos, documents files, or a folder without opening them. Regula explained that Quick Look feature generates thumbnails for each file/folder, giving users a convenient way to evaluate files before they open them. However, these cached thumbnails are stored on the computer's non-encrypted hard drive, at a known and unprotected location, even if those files/folders belong to an encrypted container, eventually revealing some of the content stored on encrypted drives. Patrick Wardle, chief research officer at Digital Security, equally shared the concern, saying tha

Apple macOS Bug Reveals Passwords for APFS Encrypted Volumes in Plaintext

Apple macOS Bug Reveals Passwords for APFS Encrypted Volumes in Plaintext
Mar 29, 2018
A severe programming bug has been found in APFS file system for macOS High Sierra operating system that exposes passwords of encrypted external drives in plain text. Introduced two years ago, APFS ( Apple File System ) is an optimized file system for flash and SSD-based storage solutions running MacOS, iOS, tvOS or WatchOS, and promises strong encryption and better performance. Discovered by forensic analyst Sarah Edwards, the bug leaves encryption password for a newly created APFS volume (e.g., encrypting USB drive using Disk Utility) in the unified logs in plaintext, as well as while encrypting previously created but unencrypted volumes. "Why is this a big deal? Well, passwords stored in plaintext can be discovered by anyone with unauthorized access to your machine, and malware can collect log files as well and send them off to someone with malicious intent," Edwards said. The password for an encrypted APFS volume can easily be retrieved by running following sim

How to Hack Apple Mac Encryption Password in Just 30 Seconds

How to Hack Apple Mac Encryption Password in Just 30 Seconds
Dec 16, 2016
Macintosh computers are often considered to be safer than those running Windows operating system, but a recently discovered attack technique proves it all wrong. All an attacker needs is a $300 device to seize full control of your Mac or MacBook. Swedish hacker and penetration tester Ulf Frisk has developed a new device that can steal the password from virtually any Mac laptop while it is sleeping or even locked in just 30 seconds, allowing hackers to unlock any Mac computer and even decrypt the files on its hard drive. So, next time when you leave your Apple's laptop unattended, be sure to shut it down completely rather than just putting the system in sleep mode or locked. Here's How an Attacker can steal your Mac FileVault2 Password The researcher devised this technique by exploiting two designing flaws he discovered last July in Apple's FileVault2 full-disk encryption software. The first issue is that the Mac system does not protect itself against Direc

Press Shift + F10 during Windows 10 Upgrade to Launch Root CLI & bypass BitLocker

Press Shift + F10 during Windows 10 Upgrade to Launch Root CLI & bypass BitLocker
Nov 30, 2016
If your computer's security relies on Windows BitLocker Hard Drive Encryption software, then Beware! Because anyone with physical access to your PC can still access your files within few seconds. All an attacker need to do is hold SHIFT+F10 during Windows 10 update procedure. Security researcher Sami Laiho discovered this simple method of bypassing BitLocker, wherein an attacker can open a command-line interface with System privileges just by holding SHIFT+F10 while a Windows 10 PC is installing a new OS build. The command-line interface (CLI) then grants the attacker full access to the computer's hard drive, even when the victim has enabled BitLocker disk encryption feature. Laiho explains that during the installation of a new build (Windows 10 upgrade), the operating system disables BitLocker while the Windows PE installs a new image of the main Windows 10 OS. "The installation [Windows 10 upgrade] of a new build is done by reimaging the machine and the im

VeraCrypt Audit Reveals Critical Security Flaws — Update Now

VeraCrypt Audit Reveals Critical Security Flaws — Update Now
Oct 18, 2016
After TrueCrypt mysteriously discontinued its service, VeraCrypt became the most popular open source disk encryption software used by activists, journalists, as well as privacy conscious people. First of all, there is no such thing as a perfect, bug-free software. Even the most rigorously tested software, like the ones that operate SCADA Systems, medical devices, and aviation software, have flaws. Vulnerabilities are an unfortunate reality for every software product, but there is always space for improvements. Due to the enormous popularity of VeraCrypt, security researchers from the OSTIF (The Open Source Technology Improvement Fund) agreed to audit VeraCrypt independently and hired researchers from QuarksLab in August to lead the audit. And it seems like VeraCrypt is not exactly flawless either. Now after one month of the audit, researchers have discovered a number of security issues, including 8 critical, 3 medium, and 15 low-severity vulnerabilities in the popular

Someone is Spying on Researchers Behind VeraCrypt Security Audit
Aug 16, 2016
After TrueCrypt mysteriously discontinued itself, VeraCrypt became the most popular open source disk encryption software used by activists, journalists, and privacy conscious people. Due to the huge popularity of VeraCrypt, security researchers from the OSTIF ( The Open Source Technology Improvement Fund ) announced at the beginning of this month that it had agreed to audit VeraCrypt independently. Using funds donated by DuckDuckGo and VikingVPN, the OSTIC hired vulnerability researchers from QuarksLab to lead the audit, which would look for zero-day vulnerabilities and other security holes in VeraCrypt's code. Now, the most troubling part comes here: The OSTIF announced Saturday that its confidential PGP-encrypted communications with QuarkLabs about the security audit of VeraCrypt were mysteriously intercepted. "We have now had a total of four email messages disappear without a trace, stemming from multiple independent senders." the OSTIF said . "Not

How to Crack Android Full Disk Encryption on Qualcomm Devices
Jul 01, 2016
The heated battle between Apple and the FBI provoked a lot of talk about Encryption – the technology that has been used to keep all your bits and bytes as safe as possible. We can not say a lot about Apple's users, but Android users are at severe risk when it comes to encryption of their personal and sensitive data. Android's full-disk encryption can be cracked much more easily than expected with brute force attack and some patience, affecting potentially hundreds of millions of mobile devices. And the worst part: There may not be a full fix available for current Android handsets in the market. Google started implementing Full Disk Encryption on Android by default with Android 5.0 Lollipop. Full disk encryption (FDE) can prevent both hackers and even powerful law enforcement agencies from gaining unauthorized access to device's data. Android's disk encryption, in short, is the process of encoding all user's data on an Android device before ever wri

The FBI and other law enforcement agencies have waged legal war on encryption and privacy technologies. You may have heard many news stories about the legal battle between Apple and the FBI over unlocking an iPhone that belonged to the San Bernardino shooter. However, that was just one battle in a much larger fight. Now, in an effort to make its iPhone surveillance-and-hack proof, Apple has rehired security expert and cryptographer Jon Callas , who co-founded the widely-used email encryption software PGP and the secure-messaging system Silent Circle that sells the Blackphone. This is not Apple's first effort over its iPhone security . Just a few months back, the company hired Frederic Jacobs , one of the key developers of Signal — World's most secure, open source and encrypted messaging app . Now Apple has rehired Callas, who has previously worked for Apple twice, first from 1995 to 1997 and then from 2009 to 2011. During his second joining, Callas designed a ful

Subgraph OS — Secure Linux Operating System for Non-Technical Users
Mar 04, 2016
Information security and privacy are consistently hot topics after Edward Snowden revelations of NSA's global surveillance that brought the world's attention towards data protection and encryption as never before. Moreover, just days after Windows 10 's successful launch last summer, we saw various default settings in the Microsoft's newest OS that compromise users' privacy , making a large number of geeks, as well as regular users, migrate to Linux. However, the problem is that majority of users are not friendly to the Linux environment. They don't know how to configure their machine with right privacy and security settings, which makes them still open to hacking and surveillance. However, this gaping hole can be filled with a  Debian-based  Security-focused Linux operating system called Subgraph OS: A key solution to your Privacy Fear. Subgraph OS is a feather weighted Linux flavor that aims to combat hacking attacks easier, even on fai

Dec 29, 2016
Have you recently purchased a Windows computer? Congratulations! As your new Windows computer has inbuilt disk encryption feature that is turned on by default in order to protect your data in case your device is lost or stolen. Moreover, In case you lost your encryption keys then don't worry, Microsoft has a copy of your Recovery Key. But Wait! If Microsoft already has your Disk Encryption Keys then what's the use of using disk encryption feature? Doesn't Encryption mean Only you can unlock your disk ? Microsoft Probably Holds your Encryption Keys Since the launch of Windows 8.1, Microsoft is offering disk encryption as a built-in feature for Windows laptops, Windows phones and other devices. However, there is a little-known fact, highlighted by The Intercept, that if you have logged into Windows 10 using your Microsoft account, your system had automatically uploaded a copy of your recovery key to Microsoft's servers secretly, and you can't pre

Google Makes Full-Disk Encryption Mandatory for New Android 6.0 Devices
Oct 20, 2015
Yes, Google wants you to keep your bits and bytes as safe as possible through encryption. With the launch of Android 5.0 Lollipop last year, Google wanted to make full disk Encryption mandatory , but unfortunately, the idea did not go too well. However, Google thinks the idea will go right this time, and it will try again to require full-disk encryption by default for devices that release with the newest Android 6.0 Marshmallow and higher versions. Google has published the new version of the Android Compatibility Definition Document ( PDF ), mandating Android encryption with a couple of exceptions in Android 6.0 Marshmallow. The document reads: "For device implementations supporting full-disk encryption and with Advanced Encryption Standard (AES) crypto performance above 50MiB/sec, the full-disk encryption MUST be enabled by default at the time the user has completed the out-of-box setup experience." New smartphones and tablets that ship with Androi

Oct 01, 2015
If you are among thousands of privacy-conscious people who are still using ' no longer available ' TrueCrypt Encryption Software , then you need to pay attention. Two critical security vulnerabilities have been discovered in the most famous encryption tool, TrueCrypt, that could expose the user's data to hackers if exploited. TrueCrypt was audited earlier this by a team of Security researchers and found to be backdoor-free . James Forshaw , Security researcher with Google's Project Zero — which looks for zero-day exploits — has found a pair of privilege elevation flaws in TrueCrypt package. Last year, TrueCrypt project was dropped after its mysterious developers had claimed the Windows disk-encryption software had ' unfixed security issues '. TrueCrypt is a widely-used ' On-the-Fly ' Open source Hard disk encryption program. Reportedly, TrueCrypt vulnerabilities would not directly allow an attacker to decrypt drive data. Instead, successful exploitation
