MY TAKE: Why monetizing data lakes will require applying ‘attribute-based’ access rules to encryption

The Last Watchdog

They outlined why something called attribute-based encryption, or ABE, has emerged as the basis for a new form of agile cryptography that we will need in order to kick digital transformation into high gear. PKI is the authentication and encryption framework on which the Internet is built. This creates exposure.

Thales Cloud Protection & Licensing

Cybercriminals use it as a launching pad to block access to business-critical systems by encrypting data in files, databases, or entire computer systems, until the victim pays a ransom.

Understanding Brute Force Attacks: The Persistent Threat in Cybersecurity

Webroot

Unlike Central Processing Units (CPUs) that process tasks sequentially, GPUs can perform thousands of operations simultaneously, drastically reducing the time required to crack passwords or encryption keys. This brute force capability poses a significant threat to systems protected by weak or commonly used passwords.

VulnRecap 2/26/24 – VMWare, Apple, ScreenConnect Face Risks

eSecurity Planet

The fix: System administrators are encouraged to install the Exchange Server 2019 Cumulative Update 14 (CU14), which was issued in February 2024 and enabled NTLM credentials Relay Protection. The problem: CVE-2024-22245 and CVE-2024-22250 put Windows domains vulnerable to authentication relay and session hijack attacks.

Microsoft provides more mitigation instructions for the PetitPotam attack

Malwarebytes

The attack could force remote Windows systems to reveal password hashes that could then be easily cracked. Microsoft quickly sent out an advisory for system administrators to stop using the now deprecated Windows NT LAN Manager (NTLM) to thwart an attack. The authentication process does not require the plaintext password.

How Secure Shell (SSH) Keys Work

Security Boulevard

SSH authenticates the parties involved and allows them to exchange commands and output via multiple data manipulation techniques. As Justin Elingwood of DigitalOcean explains , SSH encrypts data exchanged between two parties using a client-server model. The most common means of authentication is via SSH asymmetric key pairs.

Patch now! Microsoft Exchange attacks target ProxyShell vulnerabilities

Malwarebytes

The vulnerability allows a remote user to bypass the authentication process. The vulnerability allows an authenticated user to execute arbitrary code in the context of SYSTEM and write arbitrary files. PetitPotam uses the EfsRpcOpenFileRaw function of the Microsoft Encrypting File System Remote Protocol (MS-EFSRPC) API.
