According to researchers at Belgium's KU Leuven, attackers can exploit a fundamental design flaw in the IEEE 802.11 Wi-Fi standard to trick victims into connecting to a less secure wireless network. The Virtual Private Network (VPN) review site Top10VPN, which worked with one of the KU Leuven researchers to release details about the flaw, warns that such attacks increase the risk of traffic interception and manipulation. The flaw impacts Wi-Fi clients across all Operating Systems (OS).

Researchers have found almost a dozen security flaws that affect the GE HealthCare Vivid Ultrasound product family. The exploitation of these vulnerabilities could allow malicious actors to tamper with patient data and install ransomware. From implanting ransomware on the ultrasound machine to accessing and manipulating patient data on vulnerable devices, the Operational Technology (OT) security vendor Nozomi Networks said these flaws have many effects.

Researchers have discovered a sophisticated cyber campaign targeting US Artificial Intelligence (AI) organizations. "UNK_SweetSpecter," a May 2024 campaign, uses the "SugarGh0st RAT," a "Gh0stRAT"-based Remote Access Trojan (RAT). This variant, which Chinese-speaking threat actors have used, now targets AI-related entities. Proofpoint reported that the attacks used a free email account to send AI-themed lures to open zip archives. This article continues to discuss the campaign involving the SugarGh0st RAT variant.

The North Korean hacker group "Kimsuky" is now using "Gomir," a new Linux malware and version of the GoBear backdoor. Kimsuky is a state-sponsored threat actor connected to North Korea's military intelligence, the Reconnaissance General Bureau (RGB). Symantec researchers found a Linux variant of the GoBear backdoor while investigating a campaign reported by researchers at the SW2 threat intelligence company in early February 2024 that targeted South Korean government organizations. This article continues to discuss the Kimsuky hackers' use of a new Linux backdoor.

According to Check Point, 61 percent of organizations reported cloud security breaches in the past year, up from 24 percent the year before. Over 800 cloud and cybersecurity professionals provided their insights to the 2024 Cloud Security Report.
