BitLocker | Breaking Cybersecurity News | The Hacker News

Romanian cybersecurity company Bitdefender has released a free decryptor to help victims recover data encrypted using the ShrinkLocker ransomware. The decryptor is the result of a comprehensive analysis of ShrinkLocker's inner workings, allowing the researchers to discover a "specific window of opportunity for data recovery immediately after the removal of protectors from BitLocker-encrypted disks." ShrinkLocker was first documented in May 2024 by Kaspersky, which found the malware's use of Microsoft's native BitLocker utility for encrypting files as part of extortion attacks targeting Mexico, Indonesia, and Jordan. It appears to have been adapted from benign ten-year-old code. Bitdefender, which investigated a ShrinkLocker incident targeting an unnamed healthcare company in the Middle East, said the attack likely originated from a machine belonging to a contractor, once again highlighting how threat actors are increasingly abusing trusted relationships to ...

An analysis of a nascent ransomware strain called RansomHub has revealed it to be an updated and rebranded version of Knight ransomware, itself an evolution of another ransomware known as Cyclops. Knight (aka Cyclops 2.0) ransomware first arrived in May 2023, employing double extortion tactics to steal and encrypt victims' data for financial gain. It's operational across multiple platforms, including Windows, Linux, macOS, ESXi, and Android. Advertised and sold on the RAMP cybercrime forum, attacks involving the ransomware have been found to leverage phishing and spear-phishing campaigns as a distribution vector in the form of malicious attachments. The ransomware-as-a-service (RaaS) operation has since shut down as of late February 2024, when its source code was put up for sale , raising the possibility that it may have changed hands to a different actor, who subsequently decided to update and relaunch it under the RansomHub brand. RansomHub, which posted its first v...

In recent years, artificial intelligence (AI) has begun revolutionizing Identity Access Management (IAM), reshaping how cybersecurity is approached in this crucial field. Leveraging AI in IAM is about tapping into its analytical capabilities to monitor access patterns and identify anomalies that could signal a potential security breach. The focus has expanded beyond merely managing human identities — now, autonomous systems, APIs, and connected devices also fall within the realm of AI-driven IAM, creating a dynamic security ecosystem that adapts and evolves in response to sophisticated cyber threats. The Role of AI and Machine Learning in IAM AI and machine learning (ML) are creating a more robust, proactive IAM system that continuously learns from the environment to enhance security. Let's explore how AI impacts key IAM components: Intelligent Monitoring and Anomaly Detection AI enables continuous monitoring of both human and non-human identities , including APIs, service acc...

Microsoft's threat intelligence division on Wednesday assessed that a subgroup of the Iranian threat actor tracked as  Phosphorus  is conducting ransomware attacks as a "form of moonlighting" for personal gain. The tech giant, which is monitoring the activity cluster under the moniker  DEV-0270  (aka Nemesis Kitten), said it's operated by a company that functions under the public aliases Secnerd and Lifeweb, citing infrastructure overlaps between the group and the two organizations. "DEV-0270 leverages exploits for high-severity vulnerabilities to gain access to devices and is known for the early adoption of newly disclosed vulnerabilities," Microsoft  said . "DEV-0270 also extensively uses living-off-the-land binaries (LOLBINs) throughout the attack chain for discovery and credential access. This extends to its abuse of the built-in BitLocker tool to encrypt files on compromised devices." The use of BitLocker and DiskCryptor by Iranian actor...

A ransomware group with an Iranian operational connection has been linked to a string of file-encrypting malware attacks targeting organizations in Israel, the U.S., Europe, and Australia. Cybersecurity firm Secureworks attributed the intrusions to a threat actor it tracks under the moniker Cobalt Mirage, which it said is linked to an Iranian hacking crew dubbed Cobalt Illusion (aka APT35, Charming Kitten, Newscaster, or Phosphorus). "Elements of Cobalt Mirage activity have been  reported  as  Phosphorus  and  TunnelVision ," Secureworks Counter Threat Unit (CTU)  said  in a report shared with The Hacker News. The threat actor is said to have conducted two different sets of intrusions, one of which relates to opportunistic ransomware attacks involving the use of legitimate tools like  BitLocker  and DiskCryptor for financial gain. The second set of attacks are more targeted, carried out with the primary goal of securing access and gathe...

Microsoft has introduced a new password-protected folder within its OneDrive online file storage service that will allow you to keep your sensitive and important files protected and secured with an extra layer of authentication. Dubbed Personal Vault , the new OneDrive folder can only be accessed with an additional step of identity verification, such as your fingerprint, face, PIN, or a two-factor authentication code sent to you via email or SMS. The Personal Vault folder will appear next to other folders in the OneDrive app like your Documents and Pictures, but it will be locked and prompt you for an additional code each time you try to access them via the web, PC, or mobile devices, thus keeping them more secure in the event when someone gains access to your account or your device. Microsoft suggests this new protected area in OneDrive would be useful for users to store more sensitive and personal files like copies of passport, tax, car or home documents, identification cards,...

It's been a terrible new-year-starting for Intel. Researchers warn of a new attack which can be carried out in less than 30 seconds and potentially affects millions of laptops globally. As Intel was rushing to roll out patches for Meltdown and Spectre vulnerabilities , security researchers have discovered a new critical security flaw in Intel hardware that could allow hackers to access corporate laptops remotely. Finnish cyber security firm F-Secure reported unsafe and misleading default behaviour within Intel Active Management Technology (AMT) that could allow an attacker to bypass login processes and take complete control over a user's device in less than 30 seconds. AMT is a feature that comes with Intel-based chipsets to enhance the ability of IT administrators and managed service providers for better controlling their device fleets, allowing them to remotely manage and repair PCs, workstations, and servers in their organisation. The bug allows anyone with phy...

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...

TrueCrypt , the popular and reputed open source file and disk encryption Software for Windows, OSX and Linux, has abruptly closed down Wednesday recommending its users to use Microsoft's Bitlocker. TrueCrypt is a free, open-source and cross-platform encryption program, thereby one of the world's most-used encryption tool, trusted by tens of millions of users and recommended by NSA whistleblower Edward Snowden . TRUECRYPT IS NOT SECURE On Wednesday afternoon, the users of TrueCrypt encryption tool redirected to the project's official SourceForge-hosted page that displays a mysterious security warning message that the popular encryption tool has been discontinued and that users should switch to an alternative. The official website for the TrueCrypt software warns the user that the open source encryption software is no longer secure and informs that the development of the software has been terminated. At the top of TrueCrypt page on SourceForge display...
