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...

Microsoft on Friday disclosed that it has addressed a critical security flaw impacting Power Platform , but not before it came under criticism for its failure to swiftly act on it. "The vulnerability could lead to unauthorized access to Custom Code functions used for Power Platform custom connectors," the tech giant  said . "The potential impact could be unintended information disclosure if secrets or other sensitive information were embedded in the Custom Code function." The company further noted that no customer action is required and that it found no evidence of active exploitation of the vulnerability in the wild. Tenable, which initially discovered and reported the shortcoming to Redmond on March 30, 2023,  said  the problem could enable limited, unauthorized access to cross-tenant applications and sensitive data. The cybersecurity firm said the flaw arises as a result of insufficient access control to Azure Function hosts, leading to a scenario where a t...

Cybersecurity researchers have discovered a new high-severity security flaw in PaperCut print management software for Windows that could result in remote code execution under specific circumstances. Tracked as  CVE-2023-39143  (CVSS score: 8.4), the flaw impacts PaperCut NG/MF prior to version 22.1.3. It has been described as a combination of a path traversal and file upload vulnerability. "CVE-2023-39143 enables unauthenticated attackers to potentially read, delete, and upload arbitrary files to the PaperCut MF/NG application server, resulting in remote code execution in certain configurations," Horizon3.ai's Naveen Sunkavally  said . The cybersecurity firm said that file upload leading to remote code execution is possible when the external device integration setting is enabled, which is on by default in some installations of PaperCut. Earlier this April, another remote code execution vulnerability in the same product (CVE-2023-27350, CVSS score: 9.8) and an infor...
