Dirty COW Linux Exploit | Breaking Cybersecurity News | The Hacker News

Nearly a year after the disclosure of the Dirty COW vulnerability that affected the Linux kernel, cybercriminals have started exploiting the vulnerability against Android users, researchers have warned. Publicly disclosed last year in October, Dirty COW was present in a section of the Linux kernel—a part of virtually every Linux distribution, including Red Hat, Debian, and Ubuntu—for years and was actively exploited in the wild. The vulnerability allows an unprivileged local attacker to gain root access through a race condition issue, gain access to read-only root-owned executable files, and permit remote attacks. However, security researchers from Trend Micro published a blog post on Monday disclosing that the privilege escalation vulnerability (CVE-2016-5195), known as Dirty COW, has now been actively exploited by a malware sample of ZNIU, detected as AndroidOS_ZNIU. This is the first time we have seen a malware sample to contain an exploit for the vulnerability designed

A nine-year-old critical vulnerability has been discovered in virtually all versions of the Linux operating system and is actively being exploited in the wild. Dubbed " Dirty COW ," the Linux kernel security flaw (CVE-2016-5195) is a mere privilege-escalation vulnerability, but researchers are taking it extremely seriously due to many reasons. First, it's very easy to develop exploits that work reliably. Secondly, the Dirty COW flaw exists in a section of the Linux kernel, which is a part of virtually every distro of the open-source operating system, including RedHat, Debian, and Ubuntu, released for almost a decade. And most importantly, the researchers have discovered attack code that indicates the Dirty COW vulnerability is being actively exploited in the wild. Dirty COW potentially allows any installed malicious app to gain administrative (root-level) access to a device and completely hijack it within just 5 seconds. Earlier this week, Linus Torvalds admi

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo
