Details have emerged about a vulnerability impacting the “wall” command of the util-linux package that could be potentially exploited by a bad actor to leak a user’s password or alter the clipboard on certain Linux distributions. The bug, tracked as CVE-2024-28085, has been codenamed WallEscape by security researcher Skyler Ferrante. It has been described as […]
The data wiping malware called AcidPour may have been deployed in attacks targeting four telecom providers in Ukraine, new findings from SentinelOne show. The cybersecurity firm also confirmed connections between the malware and AcidRain, tying it to threat activity clusters associated with Russian military intelligence. “AcidPour’s expanded capabilities would enable it to better disable embedded […]
A new variant of a data wiping malware called AcidRain has been detected in the wild that’s specifically designed for targeting Linux x86 devices. The malware, dubbed AcidPour, is compiled for Linux x86 devices, SentinelOne’s Juan Andres Guerrero-Saade said in a series of posts on X. “The new variant […] is an ELF binary compiled […]
Cybersecurity researchers have discovered a new Linux variant of a remote access trojan (RAT) called BIFROSE (aka Bifrost) that uses a deceptive domain mimicking VMware. “This latest version of Bifrost aims to bypass security measures and compromise targeted systems,” Palo Alto Networks Unit 42 researchers Anmol Maurya and Siddharth Sharma said. BIFROSE is one of […]
Threat hunters have discovered a new Linux malware called GTPDOOR that’s designed to be deployed in telecom networks that are adjacent to GPRS roaming exchanges (GRX) The malware is novel in the fact that it leverages the GPRS Tunnelling Protocol (GTP) for command-and-control (C2) communications. GPRS roaming allows subscribers to access their GPRS services while […]
An “intricately designed” remote access trojan (RAT) called Xeno RAT has been made available on GitHub, making it easily accessible to other actors at no extra cost. Written in C# and compatible with Windows 10 and Windows 11 operating systems, the open-source RAT comes with a “comprehensive set of features for remote system management,” according […]
A novel malware campaign has been observed targeting Redis servers for initial access with the ultimate goal of mining cryptocurrency on compromised Linux hosts. “This particular campaign involves the use of a number of novel system weakening techniques against the data store itself,” Cado security researcher Matt Muir said in a technical report. The cryptojacking […]
A reverse engineering of the firmware running on Ivanti Pulse Secure appliances has revealed numerous weaknesses, once again underscoring the challenge of securing software supply chains. Eclypsiusm, which acquired firmware version 9.1.18.2-24467.1 as part of the process, said the base operating system used by the Utah-based software company for the device is CentOS 6.4. “Pulse […]
Cybersecurity researchers have identified malicious packages on the open-source Python Package Index (PyPI) repository that deliver an information stealing malware called WhiteSnake Stealer on Windows systems. The malware-laced packages are named nigpal, figflix, telerer, seGMM, fbdebug, sGMM, myGens, NewGends, and TestLibs111. They have been uploaded by a threat actor named “WS.” “These packages incorporate Base64-encoded […]
Three new malicious packages have been discovered in the Python Package Index (PyPI) open-source repository with capabilities to deploy a cryptocurrency miner on affected Linux devices. The three harmful packages, named modularseven, driftme, and catme, attracted a total of 431 downloads over the past month before they were taken down. “These packages, upon initial use, […]
Poorly secured Linux SSH servers are being targeted by bad actors to install port scanners and dictionary attack tools with the goal of targeting other vulnerable servers and co-opting them into a network to carry out cryptocurrency mining and distributed denial-of-service (DDoS) attacks. “Threat actors can also choose to install only scanners and sell the […]
A previously unknown Linux remote access trojan called Krasue has been observed targeting telecom companies in Thailand by threat actors to main covert access to victim networks at lease since 2021. Named after a nocturnal female spirit of Southeast Asian folklore, the malware is “able to conceal its own presence during the initialization phase,” Group-IB […]
Multiple threat actors, including LockBit ransomware affiliates, are actively exploiting a recently disclosed critical security flaw in Citrix NetScaler application delivery control (ADC) and Gateway appliances to obtain initial access to target environments. The joint advisory comes from the U.S. Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Multi-State Information Sharing and […]
The Kinsing threat actors are actively exploiting a critical security flaw in vulnerable Apache ActiveMQ servers to infect Linux systems with cryptocurrency miners and rootkits. “Once Kinsing infects a system, it deploys a cryptocurrency mining script that exploits the host’s resources to mine cryptocurrencies like Bitcoin, resulting in significant damage to the infrastructure and a […]
The Pakistan-linked threat actor known as SideCopy has been observed leveraging the recent WinRAR security vulnerability in its attacks targeting Indian government entities to deliver various remote access trojans such as AllaKore RAT, Ares RAT, and DRat. Enterprise security firm SEQRITE described the campaign as multi-platform, with the attacks also designed to infiltrate Linux systems […]
An advanced strain of malware masquerading as a cryptocurrency miner has managed to fly the radar for over five years, infecting no less than one million devices around the world in the process. That’s according to findings from Kaspersky, which has codenamed the threat StripedFly, describing it as an “intricate modular framework that supports both […]
A pro-Hamas hacktivist group has been observed using a new Linux-based wiper malware dubbed BiBi-Linux Wiper, targeting Israeli entities amidst the ongoing Israeli-Hamas war. “This malware is an x64 ELF executable, lacking obfuscation or protective measures,” Security Joes said in a new report published today. “It allows attackers to specify target folders and can potentially […]
The threat actors behind ShellBot are leveraging IP addresses transformed into their hexadecimal notation to infiltrate poorly managed Linux SSH servers and deploy the DDoS malware. “The overall flow remains the same, but the download URL used by the threat actor to install ShellBot has changed from a regular IP address to a hexadecimal value,” […]
