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...

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...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

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...

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...

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 ...

In Brief A suspect of child pornography possession, Francis Rawls, who is a former Philadelphia Police Department sergeant, has been in solitary confinement without charges for last seven months and will remain until he complies with a court order forcing him to decrypt his password-protected hard drives seized in connection with a child pornography investigation. Remember Ramona Fricosu? In 2012, a Colorado woman was ordered to unlock her laptop while investigating financial fraud, but she refused to unlock it saying that she did not remember the password. Later the US Court ruled that Police can force defendants to decrypt their electronic devices, of course, as it does not violate the Fifth Amendment that prevents any citizen from having to incriminate themselves. Forget the password? It might be a smart way to avoid complying with a court order, but not every time. A Philadelphia man has been in jail for seven months and counting after being refused to comply with a c...

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...

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 ...

Data security is a big task for businesses as well as a challenge for IT leaders, whether it be securing networks or devices. Past few months, we often came across various data breaches, the largest among all was Target data breach , which cost a business nearly $50,000 in lost productivity, replacement and data recovery.  Once a bad actor has stolen your hardware or compromised your network, the ability to lock down sensitive data is predominant. To help mitigate these threats in order to protect businesses against data breaches without even damaging performance, Intel has announced its latest enterprise-class solid state drives (SSDs) that are self-encrypting, packaged with some powerful security and management features. The New Intel SSD 2500 Pro Series of solid state drives offers significant performance with hardware-based 256-bit self-encryption to reduce the impact on the performance. Intel SSD 2500 Pro Series will be offered in both 2.5-inch SATA and...
