Kimsuky APT Deploying Linux Backdoor Gomir in South Korean Cyber Attacks

The Kimsuky (aka Springtail) advanced persistent threat (APT) group, which is linked to North Korea's Reconnaissance General Bureau (RGB), has been observed deploying a Linux version of its GoBear backdoor as part of a campaign targeting South Korean organizations. The backdoor, codenamed Gomir, is "structurally almost identical to GoBear, with extensive sharing of code between

Researchers Uncover 'LLMjacking' Scheme Targeting Cloud-Hosted AI Models

Cybersecurity researchers have discovered a novel attack that employs stolen cloud credentials to target cloud-hosted large language model (LLM) services with the goal of selling access to other threat actors. The attack technique has been codenamed LLMjacking by the Sysdig Threat Research Team. "Once initial access was obtained, they exfiltrated cloud credentials and gained

North Korea's Lazarus Group Deploys New Kaolin RAT via Fake Job Lures

The North Korea-linked threat actor known as Lazarus Group employed its time-tested fabricated job lures to deliver a new remote access trojan called Kaolin RAT as part of attacks targeting specific individuals in the Asia region in summer 2023. The malware could, "aside from standard RAT functionality, change the last write timestamp of a selected file and load any received DLL

Dormakaba Locks Used in Millions of Hotel Rooms Could Be Cracked in Seconds

Security vulnerabilities discovered in Dormakaba's Saflok electronic RFID locks used in hotels could be weaponized by threat actors to forge keycards and stealthily slip into locked rooms. The shortcomings have been collectively named Unsaflok by researchers Lennert Wouters, Ian Carroll, rqu, BusesCanFly, Sam Curry, sshell, and Will Caruana. They were reported to the Zurich-based

Critical Unpatched Ray AI Platform Vulnerability Exploited for Cryptocurrency Mining

Cybersecurity researchers are warning that threat actors are actively exploiting a "disputed" and unpatched vulnerability in an open-source artificial intelligence (AI) platform called Anyscale Ray to hijack computing power for illicit cryptocurrency mining. "This vulnerability allows attackers to take over the companies' computing power and leak sensitive data," Oligo Security researchers Avi

Over 100 Malicious AI/ML Models Found on Hugging Face Platform

As many as 100 malicious artificial intelligence (AI)/machine learning (ML) models have been discovered in the Hugging Face platform. These include instances where loading a pickle file leads to code execution, software supply chain security firm JFrog said. "The model's payload grants the attacker a shell on the compromised machine, enabling them to gain full control over victims'

Ivanti Pulse Secure Found Using 11-Year-Old Linux Version and Outdated Libraries

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 Secure runs an 11

Recent SSRF Flaw in Ivanti VPN Products Undergoes Mass Exploitation

A recently disclosed server-side request forgery (SSRF) vulnerability impacting Ivanti Connect Secure and Policy Secure products has come under mass exploitation. The Shadowserver Foundation said it observed exploitation attempts originating from more than 170 unique IP addresses that aim to establish a reverse shell, among others. The attacks exploit CVE-2024-21893 (CVSS

New Threat Actor 'AeroBlade' Emerges in Espionage Attack on U.S. Aerospace

A previously undocumented threat actor has been linked to a cyber attack targeting an aerospace organization in the U.S. as part of what's suspected to be a cyber espionage mission. The BlackBerry Threat Research and Intelligence team is tracking the activity cluster as AeroBlade. Its origin is currently unknown and it's not clear if the attack was successful. "The actor used spear-phishing

New BLUFFS Bluetooth Attack Expose Devices to Adversary-in-the-Middle Attacks

New research has unearthed multiple novel attacks that break Bluetooth Classic's forward secrecy and future secrecy guarantees, resulting in adversary-in-the-middle (AitM) scenarios between two already connected peers. The issues, collectively named BLUFFS, impact Bluetooth Core Specification 4.2 through 5.4. They are tracked under the identifier CVE-2023-24023 (CVSS score: 6.8)

How to Build a Research Lab for Reverse Engineering — 4 Ways

Malware analysis is an essential part of security researcher's work. But working with malicious samples can be dangerous — it requires specialized tools to record their activity, and a secure environment to prevent unintended damage. However, manual lab setup and configuration can prove to be a laborious and time-consuming process. In this article, we'll look at 4 ways to create a reverse
