China-Backed APT ChamelGang Using Ransomware to Disguise Cyberespionage

SentinelOne researchers report that the likely China-backed APT group ChamelGang has been using ransomware as a distraction from their cyberespionage operations for the past three years. Recent targets include critical infrastructure organizations in East Asia and India, such as an aviation organization and the All India Institute of Medical Sciences. The group deploys the CatB ransomware tool towards the end of their missions to destroy evidence of data theft. This tactic allows adversarial countries to claim plausible deniability by attributing the attacks to independent cybercriminals.


Novel P2Pinfect Malware Targets Redis Servers Using Rust and Multiple Evasion Techniques

Cado Security Labs researchers recently encountered a novel malware campaign named "P2Pinfect" targeting publicly-accessible deployments of Redis data stores. The malware, written in Rust, acts as a botnet agent and includes an embedded Windows PE along with a Linux ELF executable. P2Pinfect attempts multiple Redis exploits for initial access, utilizes Rust for payload development to hinder analysis, conducts internet scanning for Redis and SSH servers, and self-replicates in a worm-like manner.


TeamViewer Breached by Alleged APT Group, Product Environment Unaffected

TeamViewer disclosed a cyberattack on their internal corporate IT environment on June 26, 2024. Security firms NCC Group and Health-ISAC allege the APT29 hacking group, linked to Russia's SVR, is behind the attack. TeamViewer states there is no evidence the breach affected the product environment or customer data, and investigations are ongoing. With over 640,000 customers and 2.5 billion installs, any TeamViewer breach is a significant concern due to the product's widespread use and potential for attackers to gain full access to internal networks.


Massive Supply Chain Attack Linked to Single Operator via Leaked Cloudflare Keys

Researchers have traced the recent supply chain attack affecting tens of millions of websites via Polyfill.io, BootCDN, Bootcss, and Staticfile CDNs to a single operator. Accidentally exposed Cloudflare API keys in a public GitHub repository allowed researchers to establish the common entity behind the CDN services. Evidence suggests the attack may have been ongoing since June 2023, with a primitive version of the injected malicious code circulating via BootCSS. The full scope of the impact is yet to be assessed as the threat actors could potentially deploy hoarded domains, turning the incident into a whack-a-mole situation.


New 'Poseidon' Mac Stealer Malware Distributed via Malicious Google Ads

Jérôme Segura reports that a new Mac stealer malware called 'Poseidon' is being distributed via malicious Google ads disguised as the Arc browser. The malware, previously tracked as OSX.RodStealer, is actively being developed as an Atomic Stealer competitor with added features like stealing VPN configurations. The threat actor Rodrigo4 rebranded the malware for better publicity. Clicking the malicious ad leads to a fake Arc download site delivering a malicious DMG installer. Malwarebytes for Mac detects this campaign and recommends using web protection to block malicious ads and websites.

Wiz Research discovered an easy-to-exploit Remote Code Execution vulnerability (CVE-2024-37032) in Ollama, a popular open-source project for running AI models. The vulnerability, dubbed "Probllama", allows attackers to overwrite files on the server via a Path Traversal exploit in the /api/pull endpoint when pulling models from untrusted registries. In Docker deployments, this can lead to RCE as the server runs with root privileges. Ollama lacks built-in authentication, exposing instances to attack if not protected by a reverse-proxy. Upgrade to Ollama 0.1.34+ to mitigate.


Google's Project Naptime Enables LLMs to Conduct Automated Vulnerability Research

Google researchers Sergei Glazunov and Mark Brand have developed Project Naptime, a framework that allows large language models (LLMs) to perform vulnerability research similar to human security experts. The architecture provides the AI agent with specialized tools to navigate codebases, run fuzzing scripts, observe program behavior, and monitor progress. Project Naptime outperformed GPT-4 Turbo in identifying buffer overflow and memory corruption flaws according to the CYBERSECEVAL 2 benchmarks. The researchers state that this approach enhances the agent's ability to accurately identify and analyze vulnerabilities in a reproducible manner.


Mozilla Launches 0Din Bug Bounty Program for GenAI Security

Mozilla believes that securing GenAI technologies is a shared responsibility too complex for a single entity to handle alone. To address emerging risks of malicious use, Mozilla is investing in the next generation of GenAI security with the 0Day Investigative Network (0Din), a bug bounty program focused on identifying and fixing vulnerabilities in large language models (LLMs) and other deep learning technologies beyond just the application layer. 0Din aims to help researchers contribute to developing new security frameworks and best practices for GenAI, shaping the future of secure AI technologies.

CISOs' Expanding Role: Balancing Technical and Business Risks

Jon Oltsik, analyst at Enterprise Strategy Group, discusses the growing responsibilities of CISOs beyond just technical aspects, including working with executives, regulators, and CFOs on budgeting and translating cyber risks to the business. Chirag Joshi, CISO and founder of 7 Rules Cyber consultancy, suggests separating operational and risk responsibilities for improved risk management. However, this separation could lead to accountability challenges and potential friction points around budgets and application maintenance decisions.


CSOs Can Lose Jobs Due to Overconfidence, Complexity, and Complacency

Steve Tcherchian from XYPRO.com says overconfidence in unproven security solutions creates gaps and a false sense of security. Richard Watson from EY notes promoting runaway complexity adds cost and weakens defenses. Scott Hawk from Velaspan warns that shortchanging GRC can lead to overspending and misalignment with the business. Richard Caralli from Axio emphasizes the importance of aligning cybersecurity with enterprise objectives. Complacency and believing everything is under control is the biggest career-crippling mistake according to Howard Taylor from Radware.


The Evolving Role of the CISO: Navigating Regulatory Challenges and Liability Risks

Jennifer Leggio discusses how the role of the CISO has evolved to encompass a myriad of challenges, from stringent regulatory requirements to heightened legal liabilities stemming from data breaches and compliance complexities. Robert Hansen emphasizes the importance of CISOs staying on top of the constantly changing regulatory landscape and suggests seeking legal protection and insurance to mitigate risks. Kayla Williams highlights the limited authority CISOs often have over crucial business decisions impacting cybersecurity investments and strategies, despite being held accountable for protecting the business and customer data.
