Large Language Models | Breaking Cybersecurity News | The Hacker News

Large language models (LLMs) powering artificial intelligence (AI) tools today could be exploited to develop self-augmenting malware capable of bypassing YARA rules. "Generative AI can be used to evade string-based YARA rules by augmenting the source code of small malware variants, effectively lowering detection rates," Recorded Future  said  in a new report shared with The Hacker News. The findings are part of a red teaming exercise designed to uncover malicious use cases for AI technologies, which are  already being experimented  with by threat actors to create malware code snippets, generate phishing emails, and conduct reconnaissance on potential targets. The cybersecurity firm said it submitted to an LLM a known piece of malware called  STEELHOOK  that's associated with the APT28 hacking group, alongside its YARA rules, asking it to modify the source code to sidestep detection such that the original functionality remained intact and the generated source code wa

More than 225,000 logs containing compromised OpenAI ChatGPT credentials were made available for sale on underground markets between January and October 2023, new findings from Group-IB show. These credentials were found within  information stealer logs  associated with LummaC2, Raccoon, and RedLine stealer malware. "The number of infected devices decreased slightly in mid- and late summer but grew significantly between August and September," the Singapore-headquartered cybersecurity company  said  in its Hi-Tech Crime Trends 2023/2024 report published last week. Between June and October 2023, more than 130,000 unique hosts with access to OpenAI ChatGPT were infiltrated, a 36% increase over what was observed during the first five months of 2023. The breakdown by the top three stealer families is below - LummaC2 - 70,484 hosts Raccoon - 22,468 hosts RedLine - 15,970 hosts "The sharp increase in the number of ChatGPT credentials for sale is due to the overall rise in the numbe

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

Nation-state actors associated with Russia, North Korea, Iran, and China are experimenting with artificial intelligence (AI) and large language models (LLMs) to complement their ongoing cyber attack operations. The findings come from a report published by Microsoft in collaboration with OpenAI, both of which  said  they disrupted efforts made by five state-affiliated actors that used its AI services to perform malicious cyber activities by terminating their assets and accounts. "Language support is a natural feature of LLMs and is attractive for threat actors with continuous focus on social engineering and other techniques relying on false, deceptive communications tailored to their targets' jobs, professional networks, and other relationships," Microsoft  said  in a report shared with The Hacker News. While no significant or novel attacks employing the LLMs have been detected to date, adversarial exploration of AI technologies has transcended various phases of the at

ChatGPT and similar large language models (LLMs) have added further complexity to the ever-growing online threat landscape. Cybercriminals no longer need advanced coding skills to execute fraud and other damaging attacks against online businesses and customers, thanks to bots-as-a-service, residential proxies, CAPTCHA farms, and other easily accessible tools.  Now, the latest technology damaging businesses' bottom line is  ChatGPT . Not only have ChatGPT, OpenAI, and other LLMs raised ethical issues by  training their models  on scraped data from across the internet. LLMs are negatively impacting enterprises' web traffic, which can be extremely damaging to business.  3 Risks Presented by LLMs, ChatGPT, & ChatGPT Plugins Among the threats ChatGPT and ChatGPT plugins can pose against online businesses, there are three key risks we will focus on: Content theft  (or republishing data without permission from the original source)can hurt the authority, SEO rankings, and perceived
