ELF Binary | Breaking Cybersecurity News | The Hacker News

Cybersecurity researchers have discovered a previously undocumented malware targeting Android devices that uses compromised WordPress sites as relays for its actual command-and-control (C2) servers for detection evasion. The malware, codenamed  Wpeeper , is an ELF binary that leverages the HTTPS protocol to secure its C2 communications. "Wpeeper is a typical backdoor Trojan for Android systems, supporting functions such as collecting sensitive device information, managing files and directories, uploading and downloading, and executing commands," researchers from the QiAnXin XLab team  said . The ELF binary is embedded within a repackaged application that purports to be the  UPtodown App Store  app for Android (package name "com.uptodown"), with the APK file acting as a delivery vehicle for the backdoor in a manner that evades detection. The Chinese cybersecurity firm said it discovered the malware after it detected a  Wpeeper artifact  with ...

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 for x86 (not MIPS) and while it refers to similar devices/strings, it's a largely different codebase," Guerrero-Saade  noted . AcidRain  first came to light  in the early days of the Russo-Ukrainian war, with the malware deployed against KA-SAT modems from U.S. satellite company Viasat. An ELF binary compiled for MIPS architectures, it is capable of wiping the filesystem and different known storage device files by recursively iterating over common directories for most Linux distributions. The cyber attack was  subsequently attributed  to Russia by the Five Eyes nations, along with Ukraine and the European Union. AcidPour, as t...

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 attack is facilitated by a malware codenamed Migo, a Golang ELF binary that comes fitted with compile-time obfuscation and the ability to persist on Linux machines. The cloud security company said it detected the campaign after it identified an "unusual series of commands" targeting its Redis honeypots that are engineered to lower security defenses by disabling the following configuration options - protected-mode   replica-read-only aof-rewrite-incremental-fsync , and rdb-save-incremental-fsync It's suspected that these options are turned off in order to send additional commands to the Re...

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 with a compatible version of Ares RAT. SideCopy, active since at least 2019, is  known  for its  attacks  on Indian and Afghanistan entities. It's suspected to be a sub-group of the Transparent Tribe (aka APT36) actor. "Both SideCopy and APT36 share infrastructure and code to aggressively target India," SEQRITE researcher Sathwik Ram Prakki  said  in a Monday report. Earlier this May, the group was  linked  to a phishing campaign that took advantage of lures related to India's Defence Research and Development Organization (DRDO) to deliver inform...
