As attackers gain more knowledge about how to crack static signature-detection engines, increasingly sophisticated infostealers are targeting macOS with the ability to evade Apple's built-in malware protection. According to SentinelOne researchers, three active infostealers named KeySteal, Atomic Infostealer, and CherryPie can bypass various detection engines, with variants of the first two evading XProtect. XProtect is the macOS built-in antivirus (AV) technology that scans downloaded files and apps for known malware signatures as well as removes any infected files.

The artificial intelligence company behind the popular chatbot ChatGPT has recently teamed up with the Defense Department to explore ways of using its technology to prevent veteran suicide.  According to the company’s vice president of global affairs, Anna Makanju, it’s one of several ongoing initiatives by OpenAI and the Pentagon.  Makanju also stated that OpenAI has been doing work with the Department of Defense on cybersecurity tools for open-source software that secures critical infrastructure.

The Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have released "Cybersecurity Guidance: Chinese-Manufactured Unmanned Aircraft Systems (UAS)." The guidance aims to raise awareness of threats posed by Chinese-manufactured UAS as well as provide critical infrastructure and State, Local, Tribal, and Territorial (SLTT) partners with suggested cybersecurity protections for networks and sensitive information.

According to security researchers at Jscrambler, about 6,700 WordPress websites have been infected with the Balada Injector malware after using a Popup Builder plug-in with a cross-site scripting (XSS) vulnerability tracked as CVE-2023-6000.  The researchers noted that the Balada Injector campaign is long-running (since 2017) and is an operation that has compromised more than 1 million WordPress sites in the past six years.

Quarkslab researchers discovered a set of vulnerabilities called PixieFail affecting the IPv6 network protocol stack of TianoCore's EDK II, an open-source reference implementation of the Unified Extensible Firmware Interface (UEFI) specification that is widely used in enterprise computers and servers. The flaws are in the PXE network boot process, which is critical for provisioning operating systems in data centers and high-performance computing environments. It is a standard procedure for loading operating system images from the network during boot.

A major Spanish holiday destination became the victim of ransomware last weekend, with reports claiming digital extortionists are demanding €10m ($11m).  The municipality of Calvià in the southwest of Majorca includes the popular tourist hotspot of Magaluf and attracts over one million visitors to its shores a year.  A crisis committee has been assembled to assess the attack's impact on local services, and an IT team is working through forensic analysis and recovery processes.  The Guardia Civil has reportedly also been contacted for assistance.

OpenAI, the developer of the AI chatbot ChatGPT and the image generator DALL-E has recently announced new measures to prevent abuse and misinformation ahead of big elections this year.  The firm announced that it was collaborating with the National Association of Secretaries of State (NASS), the oldest non-partisan professional organization for public officials in the US, to prevent the use of ChatGPT for misinformation ahead of the US Presidential Election in November.

According to new research, a vulnerability called LeftoverLocals exists in multiple brands and models of mainstream GPUs, including Apple, Qualcomm, and AMD chips, and can allow an attacker to steal large amounts of data from a GPU's memory. To exploit the vulnerability, attackers must first establish some level of operating system access on a target's device. Modern computers and servers are designed to silo data, allowing multiple users to share the same processing resources while not being able to access each other's data.

Citrix recently informed customers that two new zero-day vulnerabilities affecting its NetScaler ADC and Gateway products have been exploited in attacks.  One of the flaws tracked as CVE-2023-6548 is a medium-severity issue that allows a low-privileged authenticated attacker to execute arbitrary code on the management interface remotely.  The second vulnerability, CVE-2023-6549, is a high-severity issue that can be exploited for denial-of-service (DoS) attacks.

Google has recently pushed out an urgent Chrome browser update to fix a trio of high-severity security defects and warned that one of the bugs is already being exploited in the wild.  Google describes the exploited zero-day, CVE-2024-0519, as an out-of-bounds memory access issue in the V8 JavaScript engine.  Google did not provide any additional details on the scope of the observed attacks or share telemetry to help defenders hunt for signs of compromise.
