Cybersecurity researchers have discovered an indirect prompt injection flaw in GitLab's artificial intelligence (AI) assistant Duo that could have allowed attackers to steal source code and inject untrusted HTML into its responses, which could then be used to direct victims to malicious websites. GitLab Duo is an artificial intelligence (AI)-powered coding assistant that enables users to write, review, and edit code. Built using Anthropic's Claude models, the service was first launched in June 2023. But as Legit Security found , GitLab Duo Chat has been susceptible to an indirect prompt injection flaw that permits attackers to "steal source code from private projects, manipulate code suggestions shown to other users, and even exfiltrate confidential, undisclosed zero-day vulnerabilities." Prompt injection refers to a class of vulnerabilities common in AI systems that enable threat actors to weaponize large language models (LLMs) to manipulate responses to user...

A Chinese-speaking threat actor tracked as UAT-6382 has been linked to the exploitation of a now-patched remote-code-execution vulnerability in Trimble Cityworks to deliver Cobalt Strike and VShell. "UAT-6382 successfully exploited CVE-2025-0944, conducted reconnaissance, and rapidly deployed a variety of web shells and custom-made malware to maintain long-term access," Cisco Talos researchers Asheer Malhotra and Brandon White said in an analysis published today. "Upon gaining access, UAT-6382 expressed a clear interest in pivoting to systems related to utility management." The network security company said it observed the attacks targeting enterprise networks of local governing bodies in the United States starting January 2025. CVE-2025-0944 (CVSS score: 8.6) refers to the deserialization of untrusted data vulnerability affecting the GIS-centric asset management software that could enable remote code execution. The vulnerability, since patched, was added to ...

A privilege escalation flaw has been demonstrated in Windows Server 2025 that makes it possible for attackers to compromise any user in Active Directory (AD). "The attack exploits the delegated Managed Service Account (dMSA) feature that was introduced in Windows Server 2025, works with the default configuration, and is trivial to implement," Akamai security researcher Yuval Gordon said in a report shared with The Hacker News. "This issue likely affects most organizations that rely on AD. In 91% of the environments we examined, we found users outside the domain admins group that had the required permissions to perform this attack." What makes the attack pathway notable is that it leverages a new feature called Delegated Managed Service Accounts ( dMSA ) that allows migration from an existing legacy service account. It was introduced in Windows Server 2025 as a mitigation to Kerberoasting attacks. The attack technique has been codenamed BadSuccessor by the w...

A recently patched pair of security flaws affecting Ivanti Endpoint Manager Mobile (EPMM) software has been exploited by a China-nexus threat actor to target a wide range of sectors across Europe, North America, and the Asia-Pacific region. The vulnerabilities, tracked as CVE-2025-4427 (CVSS score: 5.3) and CVE-2025-4428 (CVSS score: 7.2), could be chained to execute arbitrary code on a vulnerable device without requiring any authentication. They were addressed by Ivanti last week. Now, according to a report from EclecticIQ, the vulnerability chain has been abused by UNC5221 , a Chinese cyber espionage group known for its targeting of edge network appliances since at least 2023. Most recently, the hacking crew was also attributed to exploitation efforts targeting SAP NetWeaver instances susceptible to CVE-2025-31324. The Dutch cybersecurity company said the earliest exploitation activity dates back to May 15, 2025, with the attacks targeting healthcare, telecommunications, avia...

Cybersecurity researchers have uncovered multiple critical security vulnerabilities impacting the Versa Concerto network security and SD-WAN orchestration platform that could be exploited to take control of susceptible instances. It's worth noting that the identified shortcomings remain unpatched despite responsible disclosure on February 13, 2025, prompting a public release of the issues following the end of the 90-day deadline. "These vulnerabilities, when chained together, could allow an attacker to fully compromise both the application and the underlying host system," ProjectDiscovery researchers Harsh Jaiswal, Rahul Maini, and Parth Malhotra said in a report shared with The Hacker News. The security defects are listed below - CVE-2025-34025 (CVSS score: 8.6) - A privilege escalation and Docker container escape vulnerability that's caused by unsafe default mounting of host binary paths and could be exploited to gain code execution on the underlying host m...

Russian cyber threat actors have been attributed to a state-sponsored campaign targeting Western logistics entities and technology companies since 2022. The activity has been assessed to be orchestrated by APT28 (aka BlueDelta, Fancy Bear, or Forest Blizzard), which is linked to the Russian General Staff Main Intelligence Directorate (GRU) 85th Main Special Service Center, Military Unit 26165. Targets of the campaign include companies involved in the coordination, transport, and delivery of foreign assistance to Ukraine, according to a joint advisory released by agencies from Australia, Canada, Czechia, Denmark, Estonia, France, Germany, the Netherlands, Poland, the United Kingdom, and the United States. "This cyber espionage-oriented campaign targeting logistics entities and technology companies uses a mix of previously disclosed TTPs and is likely connected to these actors' wide scale targeting of IP cameras in Ukraine and bordering NATO nations," the bulletin said...

Cybersecurity researchers have discovered risky default identity and access management (IAM) roles impacting Amazon Web Services that could open the door for attackers to escalate privileges, manipulate other AWS services, and, in some cases, even fully compromise AWS accounts. "These roles, often created automatically or recommended during setup, grant overly broad permissions, such as full S3 access," Aqua researchers Yakir Kadkoda and Ofek Itach said in an analysis. "These default roles silently introduce attack paths that allow privilege escalation, cross-service access, and even potential account compromise." The cloud security firm said it identified security issues in default IAM roles created by AWS services like SageMaker, Glue, EMR, and Lightsail. A similar flaw has also been unearthed in a popular open-source framework called Ray, which automatically creates a default IAM role (ray-autoscaler-v1) with the AmazonS3FullAccess policy. What's concer...

The official site for RVTools has been hacked to serve a compromised installer for the popular VMware environment reporting utility. "Robware.net and RVTools.com are currently offline. We are working expeditiously to restore service and appreciate your patience," the company said in a statement posted on its website. "Robware.net and RVTools.com are the only authorized and supported websites for RVTools software. Do not search for or download purported RVTools software from any other websites or sources." The development comes after security researcher Aidan Leon revealed that an infected version of the installer downloaded from the website was being used to sideload a malicious DLL that turned out to be a known malware loader called Bumblebee . It's currently not known how long the trojanized version of RVTools had been available for download and how many had installed it before the site was taken offline. In the interim, users are recommended to veri...

Researchers at ETH Zürich have discovered yet another security flaw that they say impacts all modern Intel CPUs and causes them to leak sensitive data from memory, showing that the vulnerability known as Spectre continues to haunt computer systems after more than seven years. The vulnerability, referred to as Branch Privilege Injection (BPI), "can be exploited to misuse the prediction calculations of the CPU (central processing unit) in order to gain unauthorized access to information from other processor users," ETH Zurich said . Kaveh Razavi, head of the Computer Security Group (COMSEC) and one of the authors of the study, said the shortcoming affects all Intel processors, potentially enabling bad actors to read the contents of the processor's cache and the working memory of another user of the same CPU. The attack leverages what's called Branch Predictor Race Conditions ( BPRC ) that emerge when a processor switches between prediction calculations for two use...

Imagine this: Your organization completed its annual penetration test in January, earning high marks for security compliance. In February, your development team deployed a routine software update. By April, attackers had already exploited a vulnerability introduced in that February update, gaining access to customer data weeks before being finally detected. This situation isn't theoretical: it plays out repeatedly as organizations realize that point-in-time compliance testing can't protect against vulnerabilities introduced after the assessment. According to Verizons 2025 Data Breach Investigation Report , the exploitation of vulnerabilities rose 34% year-over-year. While compliance frameworks provide important security guidelines, companies need continuous security validation to identify and remediate new vulnerabilities before attackers can exploit them. Here's what you need to know about pen testing to meet compliance standards — and why you should adopt continuous penetratio...

A Russia-linked threat actor has been attributed to a cyber espionage operation targeting webmail servers such as Roundcube, Horde, MDaemon, and Zimbra via cross-site scripting (XSS) vulnerabilities, including a then-zero-day in MDaemon, according to new findings from ESET. The activity, which commenced in 2023, has been codenamed Operation RoundPress by the Slovak cybersecurity company. It has been attributed with medium confidence to the Russian state-sponsored hacking group tracked as APT28, which is also referred to as BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422. "The ultimate goal of this operation is to steal confidential data from specific email accounts," ESET researcher Matthieu Faou said in a report shared with The Hacker News. "Most victims are governmental entities and defense companies in Eastern Europe, although we have observed governments in Africa, Europe, and South ...

Samsung has released software updates to address a critical security flaw in MagicINFO 9 Server that has been actively exploited in the wild. The vulnerability, tracked as CVE-2025-4632 (CVSS score: 9.8), has been described as a path traversal flaw. "Improper limitation of a pathname to a restricted directory vulnerability in Samsung MagicINFO 9 Server version before 21.1052 allows attackers to write arbitrary files as system authority," according to an advisory for the flaw. It's worth noting that CVE-2025-4632 is a patch bypass for CVE-2024-7399, another path traversal flaw in the same product that was remediated by Samsung in August 2024. CVE-2025-4632 has since been exploited in the wild shortly after the release of a proof-of-concept (PoC) by SSD Disclosure on April 30, 2025, in some instances to even deploy the Mirai botnet. While it was initially assumed that the attacks were targeting CVE-2024-7399, cybersecurity company Huntress first revealed the exist...

At least two different cybercrime groups BianLian and RansomExx are said to have exploited a recently disclosed security flaw in SAP NetWeaver tracked as CVE-2025-31324 , indicating that multiple threat actors are taking advantage of the bug. Cybersecurity firm ReliaQuest, in a new update published today, said it uncovered evidence suggesting involvement from the BianLian data extortion crew and the RansomExx ransomware family, which is traced by Microsoft under the moniker Storm-2460. BianLian is assessed to be involved in at least one incident based on infrastructure links to IP addresses previously identified as attributed to the e-crime group. "We identified a server at 184[.]174[.]96[.]74 hosting reverse proxy services initiated by the rs64.exe executable," the company said. "This server is related to another IP, 184[.]174[.]96[.]70, operated by the same hosting provider. The second IP had previously been flagged as a command-and-control (C2) server associat...

Organizations across industries are experiencing significant escalations in cyberattacks, particularly targeting critical infrastructure providers and cloud-based enterprises. Verizon's recently released 2025 Data Breach Investigations Report found an 18% YoY increase in confirmed breaches, with the exploitation of vulnerabilities as an initial access step growing by 34%.  As attacks rise in volume and impact, many organizations turn to security tools and compliance standards as their first line of defense. While both are important and necessary components to mitigating cyber risk, they alone are not a silver bullet solution. Effective security requires people, process, and technology, but people must serve as the primary drivers. Your tools and checklists are only as strong as the practitioners implementing them at scale.  This heightens the importance of investing in offensive operations training across every role in the security function. Too often, offensive operation...
