Last week, CISA added CVE-2024-1086 to its Known Exploited Vulnerability Catalog. CVE-2024-1086, a use-after-free vulnerability in the Linux kernel’s netfilter, was disclosed on January 31, 2024 and assigned a CVSS of 7.8 (High). If successfully exploited, it could allow threat actors to achieve local privilege escalation. While there was no evidence of active exploitation at the time of disclosure, we have since observed adversaries targeting CVE-2024-1086 in the wild.

The cybersecurity landscape has recently been shaken by a surge in activity involving a Mirai distributed denial-of-service (DDoS) botnet variant known as CatDDoS. Over the past three months, threat actors have aggressively exploited more than 80 vulnerabilities to spread this malware. In this blog, we explore the recent CatDDoS attacks, the targeted sectors, and the implications for cybersecurity practices.

As cybersecurity leaders try to get ahead of threats to their organization, they're increasingly seeking ways to get off the hamster wheel of chasing countless CVEs (common vulnerabilities and exposures). The brass ring that most CISOs reach for today is prioritization of exposures in their infrastructure (and beyond), so their teams can focus on tackling the ones that present the greatest risk. In some cases, the highest priority exposures will still be critical CVEs on mission critical assets.

Today, the average application contains thousands of moving parts. Organizations deploy to multi-cloud environments with containers and microservices, using a combination of code written by internal teams, generated by AI, and curated by third parties. Security teams face a tall order in keeping these complex applications secure, especially given the increasing number of software supply chain attacks.

With cyber threats constantly evolving, organizations must ensure that their approach to identifying and mitigating vulnerabilities is always up to date. Purple teaming can play a vital role in helping them to achieve this. Purple teaming involves red and blue teams collaborating on an ongoing basis to maximize their impact. Read on to discover how purple teaming enables businesses to enhance and accelerate their approach to identifying and mitigating security vulnerabilities.

The Synopsys Cybersecurity Research Center (CyRC) has exposed prompt injection vulnerabilities in the EmailGPT service. EmailGPT is an API service and Google Chrome extension that assists users in writing emails inside Gmail using OpenAI's GPT models. The service uses an API service that allows a malicious user to inject a direct prompt and take over the service logic. Attackers can exploit the issue by forcing the AI service to leak the standard hard-coded system prompts and/or execute unwanted prompts.

Who doesn’t like a good bedtime story from Grandma? In today’s landscape, more and more organizations are turning to intelligent chatbots or large language models (LLMs) to boost service quality and client support. This shift is receiving a lot of positive attention, offering a welcome change given the common frustrations with bureaucratic delays and the lackluster performance of traditional automated chatbot systems.
