Linux version of LockBit ransomware targets VMware ESXi servers

 LockBit is the latest ransomware gang whose Linux encryptor has been
discovered to be focusing on the encryption of VMware ESXi virtual

The enterprise is increasingly moving to virtual machines to save
computer resources, consolidate servers, and for easier backups.

Due to this, ransomware gangs have evolved their tactics to create
Linux encryptors that specifically target the popular VMware vSphere and
ESXi virtualization platforms over the past year.

While ESXi is not strictly Linux, it does share many of its
characteristics, including the ability to run ELF64 Linux executables.

Blockchain for Access Control Systems: Draft NISTIR 8403 Available for Comment


Blockchain for Access
Control Systems: Draft NISTIR 8403 Available for Comment

NIST has released NIST Internal Report (NISTIR) 8403, Blockchain for
Access Control Systems
, for public comment.

Protecting system resources against unauthorized access is the
primary objective of an access control system. As information systems rapidly
evolve, the need for advanced access control mechanisms that support
decentralization, scalability, and trust – all major challenges for traditional
mechanisms – has grown.

Blockchain technology offers high confidence and tamper resistance
implemented in a distributed fashion without a central authority, which means
that it can be a trustable alternative for enforcing access control policies.
This document presents analyses of blockchain access control systems from the
perspectives of properties, components, architectures, and model supports, as
well as discussions on considerations for implementation.

The public comment period is open through February 7, 2022. 
See the publication details
for a copy of the draft and instructions for submitting comments.

New macOS vulnerability, “powerdir,” could lead to unauthorized user data access

 Following our discovery of the “Shrootless” vulnerability, Microsoft uncovered a new macOS vulnerability, “powerdir,” that could allow an attacker to bypass the operating system’s Transparency, Consent, and Control (TCC) technology, thereby gaining unauthorized access to a user’s protected data. We shared our findings with Apple through Coordinated Vulnerability Disclosure (CVD) via Microsoft Security Vulnerability Research (MSVR). Apple released a fix for this vulnerability, now identified as CVE-2021-30970, as part of security updates released on December 13, 2021. We encourage macOS users to apply these security updates as soon as possible.

Introduced by Apple in 2012 on macOS Mountain Lion, TCC is essentially designed to help users configure the privacy settings of their apps, such as access to the device’s camera, microphone, or location, as well as access to the user’s calendar or iCloud account, among others. To protect TCC, Apple introduced a feature that prevents unauthorized code execution and enforced a policy that restricts access to TCC to only apps with full disk access. We discovered that it is possible to programmatically change a target user’s home directory and plant a fake TCC database, which stores the consent history of app requests. If exploited on unpatched systems, this vulnerability could allow a malicious actor to potentially orchestrate an attack based on the user’s protected personal data. For example, the attacker could hijack an app installed on the device—or install their own malicious app—and access the microphone to record private conversations or capture screenshots of sensitive information displayed on the user’s screen.

It should be noted that other TCC vulnerabilities were previously reported and subsequently patched before our discovery. It was also through our examination of one of the latest fixes that we came across this bug. In fact, during this research, we had to update our proof-of-concept (POC) exploit because the initial version no longer worked on the latest macOS version, Monterey. This shows that even as macOS or other operating systems and applications become more hardened with each release, software vendors like Apple, security researchers, and the larger security community, need to continuously work together to identify and fix vulnerabilities before attackers can take advantage of them.

Microsoft security researchers continue to monitor the threat landscape to discover new vulnerabilities and attacker techniques that could affect macOS and other non-Windows devices. The discoveries and insights from our research enrich our protection technologies and solutions, such as Microsoft Defender for Endpoint, which allows organizations to gain visibility to their networks that are increasingly becoming heterogeneous. For example, this research informed the generic detection of behavior associated with this vulnerability, enabling Defender for Endpoint to immediately provide visibility and protection against exploits even before the patch is applied. Such visibility also enables organizations to detect, manage, respond to, and remediate vulnerabilities and cross-platform threats faster.

SFile (Escal) ransomware ported for Linux attacks

The operators of the SFile ransomware, also known as Escal, have ported their malware to work and encrypt files on Linux-based operating systems.

Attacks with this new Linux variant were spotted late last year, Chinese security firm Rising said in a report last week, confirmed by The Record with MalwareHunterTeam, one of the people behind the ID-Ransomware project.
The SFile (Escal) ransomware was first seen in attacks in February 2020.
Initial versions were written for encrypting Windows systems only.
Over the past two years, the ransomware has been used as part of targeted attacks against corporate and government networks. During these attacks, SFile is usually deployed to encrypt files, and leave a ransom note for victims telling them to contact the attackers via one of three emails and negotiate a ransom for the decryption key.
