The Pakistan-based advanced persistent threat (APT) group known as Transparent Tribe has exploited a two-factor authentication (2FA) tool utilized by Indian government agencies to introduce a new Linux backdoor dubbed Poseidon. According to Uptycs security researcher Tejaswini Sandapolla, “Poseidon serves as a second-stage malware payload linked to Transparent Tribe. It functions as a versatile backdoor, enabling attackers to perform a variety of malicious actions such as logging keystrokes, capturing screenshots, and managing system files remotely.” Transparent Tribe, also identified as APT36, Operation C-Major, PROJECTM, and Mythic Leopard, has a history of targeting Indian governmental bodies, military personnel, defense contractors, and educational institutions. This group frequently utilizes trojanized versions of legitimate software to carry out its attacks.

Severe Sudo Vulnerabilities Allow Local Users to Escalate to Root Access on Major Linux Distributions
July 4, 2025
By Cybersecurity Insights
Cybersecurity researchers have identified two critical vulnerabilities in the Sudo command-line utility for Linux and Unix-like systems, enabling local attackers to elevate their privileges to root on affected machines. Here’s a summary of the vulnerabilities:
CVE-2025-32462 (CVSS Score: 2.8): In versions prior to 1.9.17p1, Sudo, when configured with a sudoers file specifying a host that is neither the current host nor ALL, permits listed users to execute commands on unintended machines.
CVE-2025-32463 (CVSS Score: 9.3): In Sudo versions before 1.9.17p1, local users can gain root access as a result of the /etc/nsswitch.conf file being utilized from a user-controlled directory in conjunction with the –chroot option.
Sudo is a command-line tool designed to allow low-privileged users to execute commands as another user, typically the superuser, thereby implementing the principle of least privilege for administrative tasks.
Critical Sudo Vulnerabilities Expose Linux Systems to Root Access Risks On July 4, 2025, cybersecurity experts identified two significant vulnerabilities in the Sudo command-line utility widely used across Linux and Unix-like operating systems. These issues pose a serious threat, allowing local attackers to gain root access on affected systems, heightening…

Cybersecurity experts have unveiled a new malware campaign known as CRON#TRAP, which infiltrates Windows systems through a Linux virtual machine that harbors a backdoor for remote access. The campaign initiates with a malicious Windows shortcut (LNK) file, typically distributed as a ZIP archive in phishing emails. Researchers Den Iuzvyk and Tim Peck from Securonix highlighted that the Linux instance is pre-configured with a backdoor that automatically connects to an attacker-controlled command-and-control (C2) server. This enables attackers to maintain a hidden presence on the compromised system, facilitating further malicious activities within a concealed environment, thus evading detection by traditional antivirus solutions. The phishing messages often disguise themselves as an “OneAmerica survey.”
