Cybersecurity researchers have discovered a set of 11 living-off-the-land binaries-and-scripts ( LOLBAS ) that could be maliciously abused by threat actors to conduct post-exploitation activities.  "LOLBAS is an attack method that uses binaries and scripts that are already part of the system for malicious purposes," Pentera security researcher Nir Chako  said . "This makes it hard for security teams to distinguish between legitimate and malicious activities, since they are all performed by trusted system utilities." To that end, the Israeli cybersecurity company said it uncovered nine LOLBAS downloaders and three executors that could enable adversaries to download and execute "more robust malware" on infected hosts. This includes: MsoHtmEd.exe, Mspub.exe, ProtocolHandler.exe, ConfigSecurityPolicy.exe, InstallUtil.exe, Mshta.exe, Presentationhost.exe, Outlook.exe, MSAccess.exe, scp.exe, and sftp.exe.  "In a complete attack chain, a hacker will us...

A new malware campaign has been observed making use of malicious OpenBullet configuration files to target inexperienced cyber criminals with the goal of delivering a remote access trojan (RAT) capable of stealing sensitive information. Bot mitigation company Kasada  said  the activity is designed to "exploit trusted criminal networks," describing it as an instance of advanced threat actors "preying on beginner hackers." OpenBullet  is a legitimate  open-source pen testing tool  used for automating credential stuffing attacks. It takes in a  configuration file  that's tailored to a specific website and can combine it with a password list procured through other means to log successful attempts. "OpenBullet can be used with Puppeteer, which is a headless browser that can be used for automating web interactions," the company  said . "This makes it very easy to launch credential stuffing attacks without having to deal with browser windows popping u...

Two different North Korean nation-state actors have been linked to a cyber intrusion against NPO Mashinostroyeniya, a major Russian missile engineering company. Cybersecurity firm SentinelOne  said  it identified "two instances of North Korea related compromise of sensitive internal IT infrastructure," including a case of an email server compromise and the deployment of a Windows backdoor dubbed OpenCarrot. The breach of the Linux email server has been attributed to  ScarCruft . OpenCarrot, on the other hand, is a known implant  previously identified  as used by the Lazarus Group. The attacks were flagged in mid-May 2022. A rocket design bureau based in Reutov, NPO Mashinostroyeniya was  sanctioned  by the U.S. Treasury Department in July 2014 in  connection  to "Russia's continued attempts to destabilize eastern Ukraine and its ongoing occupation of Crimea." While both ScarCruft (aka APT37) and the Lazarus Group are affiliated to North...

In today's interconnected world, evolving security solutions to meet growing demand is more critical than ever. Collaboration across multiple solutions for intelligence gathering and information sharing is indispensable. The idea of multiple-source intelligence gathering stems from the concept that threats are rarely isolated. Hence, their detection and prevention require a comprehensive understanding of the broader landscape. A comprehensive and robust security framework should be established by aggregating resources, knowledge, and expertise from various sources. This collaborative effort allows for the analysis of diverse data sets, the identification of emerging patterns, and the timely dissemination of crucial information.  In this article, we discuss a versatile security platform that can operate in two distinct roles within a security ecosystem. This platform can function as a subscriber, actively collecting and aggregating security data from various endpoints and other so...

A group of academics has devised a "deep learning-based acoustic side-channel attack" that can be used to classify laptop keystrokes that are recorded using a nearby phone with 95% accuracy. "When trained on keystrokes recorded using the video conferencing software Zoom, an accuracy of 93% was achieved, a new best for the medium," researchers Joshua Harrison, Ehsan Toreini, and Maryam Mehrnezhad  said  in a new study published last week. Side-channel attacks  refer  to a class of  security exploits  that aim to glean insights from a system by monitoring and measuring its physical effects during the processing of sensitive data. Some of the common observable effects include runtime behavior, power consumption, electromagnetic radiation, acoustics, and cache accesses. Although a completely side-channel-free implementation does not exist, practical attacks of this kind can have damaging consequences for user privacy and security as they could be weaponize...

Vulnerable  Redis services  have been targeted by a "new, improved, dangerous" variant of a malware called SkidMap that's engineered to target a wide range of Linux distributions. "The malicious nature of this malware is to adapt to the system on which it is executed," Trustwave security researcher Radoslaw Zdonczyk  said  in an analysis published last week. Some of the Linux distribution SkidMap sets its eyes on include Alibaba, Anolis, openEuler, EulerOS, Stream, CentOS, RedHat, and Rocky. SkidMap was  first disclosed  by Trend Micro in September 2019 as a cryptocurrency mining botnet with capabilities to load malicious kernel modules that can obfuscate its activities as well as monitor the miner process. The operators of the malware have also been found camouflaging their backup command-and-control (C2) IP address on the Bitcoin blockchain, evocative of another botnet malware known as  Glupteba . "The technique of fetching real-time data from...

The U.S. Federal Bureau of Investigation (FBI) is warning about cyber crooks masquerading as legitimate non-fungible token (NFT) developers to steal cryptocurrency and other digital assets from unsuspecting users. In these fraudulent schemes, criminals either obtain direct access to NFT developer social media accounts or create look-alike accounts to promote "exclusive" new NFT releases, often employing misleading advertising campaigns that create a sense of urgency to pull them off. "Links provided in these announcements are phishing links directing victims to a spoofed website that appears to be a legitimate extension of a particular NFT project," the FBI  said  in an advisory last week. The replica websites urge potential targets to connect their cryptocurrency wallets and purchase the NFT, only for the threat actors to siphon the funds and NFTs to wallets under their control. "Contents stolen from victims' wallets are often processed through a ser...

Managed Detection and Response (MDR) has emerged as a crucial solution for organizations looking to bolster their security measures. MDR allows businesses to outsource the management of Endpoint Detection and Response (EDR) products deployed across their network domain. With real-time threat-hunting capabilities, MDR services detect and mitigate malicious activities on individual endpoints while promptly alerting the service provider's Security Operations Center (SOC) for further investigation. By leveraging the expertise of security specialists, MDR services relieve organizations of the complexities and criticality associated with security operations. Types of MDR Solutions: MDR services come in various forms, tailored to an organization's technology environment and risk requirements.  These include: Bring-Your-Own Security Stack / Hybrid Solution: MDR solutions that integrate with existing security products deployed within an environment. Full Vendor-Supplied MDR Sta...

Threat actors are using an open-source rootkit called  Reptile  to target Linux systems in South Korea. "Unlike other rootkit malware that typically only provide concealment capabilities, Reptile goes a step further by offering a reverse shell, allowing threat actors to easily take control of systems," the AhnLab Security Emergency Response Center (ASEC)  said  in a report published this week. "Port knocking is a method where the malware opens a specific port on an infected system and goes on standby. When the threat actor sends a magic packet to the system, the received packet is used as a basis to establish a connection with the C&C server." A rootkit is a malicious software program that's designed to provide privileged, root-level access to a machine while concealing its presence. At least four different campaigns have leveraged Reptile since 2022. The first use of the rootkit was  recorded  by Trend Micro in May 2022 in connection with an intr...
