The Russian threat actors recently linked to the exploitation of a now-patched vulnerability in Zimbra have been observed exploiting another vulnerability, this time in Microsoft Outlook Web Access (OWA), to target U.S. and European government entities, as well as the telecommunications, financial, hospitality, and aerospace sectors. The activity, which began on July 22, 2026, involves the weaponization of CVE-2026-42897 (CVSS score: 8.1), a cross-site scripting (XSS) vulnerability in OWA. It was flagged by Microsoft as having been exploited in attacks as far back as May 2026. Enterprise security company Proofpoint has attributed the activity to Laundry Bear (aka CL-STA-1114, TA488, UNK_PitStop, and Void Blizzard), which was recently attributed to the zero-day exploitation of CVE-2025-66376, an XSS flaw in Zimbra's Classic UI, since at least July 2025 before it was patched four months later. In these attacks, the threat actors sent out messages from adversary-controlled P...

The Federal Communications Commission (FCC) added foreign-produced mobile robots and networked power inverters to its Covered List on July 28. The move generally prevents new models from receiving the equipment authorization required for import, marketing, or sale in the US. Previously authorized models can still be sold, and devices people already own are unaffected. Federal purchases and use are also unaffected by this FCC action. Previously authorized hardware can keep receiving qualifying security and compatibility updates. FCC rules otherwise exclude covered equipment from certification procedures for Class I and Class II permissive changes. The FCC's Office of Engineering and Technology granted a waiver the same day, through at least January 1, 2029, for software and firmware changes that "patch vulnerabilities and facilitate compatibility with different operating systems." Manufacturers can apply through the FCC for Conditional Approval. The Department of...

Amazon has tied the September 2025 hijack of the npm packages debug and chalk to North Korea. For ten months, the incident sat in the public record as crypto theft: a maintainer phished through a lookalike npm domain and a wallet-draining script pushed into at least 18 packages carrying more than 2 billion weekly downloads between them. The original Aikido and Wiz reports did not attribute the incident to North Korea. In research published July 29, Amazon Threat Intelligence assesses with medium confidence that the group behind the March 2026 axios compromise was behind it. The same group planted a trojanized file in a small package called typo-crypto in March 2025, according to Amazon, a full year before it reached axios. Analysts found it while chasing a domain registered in 2025 that surfaced during the axios investigation. Downloads were low, but the tradecraft "aligns with what we later observed in attacks on more popular packages," Amazon wrote, and the compa...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a newly disclosed security flaw impacting Cisco Secure Firewall Management Center (FMC) Software to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of zero-day exploitation. The vulnerability, assigned CVE-2026-20316 (CVSS score: 5.3), could permit an unauthenticated, remote attacker to log in to an affected device using a low-privilege account to access sensitive data within susceptible systems. "This vulnerability is due to the presence of static user credentials for a low-privileged account," Cisco said in an alert released Wednesday. "An attacker could exploit this vulnerability by using the account to log in to an affected system." "A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user."

Ruby on Rails has released fixes for a critical Active Storage vulnerability that could let unauthenticated attackers read arbitrary files from application servers through crafted image uploads. Tracked as CVE-2026-66066 (CVSS score: 9.5), the flaw can expose the Rails process environment and secrets such as secret_key_base , the Rails master key, database passwords, cloud storage credentials, and API tokens. Those secrets may enable remote code execution (RCE) or lateral movement into connected systems. Affected applications use libvips for Active Storage image processing and accept image uploads from untrusted users. Rails selects Vips under load_defaults 7.0 , and later defaults retain it. Ethiack and GMO Flatt Security list the affected ranges as Rails 7.0.0 through 7.2.3.1, Rails 8.0.0 through 8.0.5, and Rails 8.1.0 through 8.1.3. Rails 6.0.0 through 6.1.7.10 releases are affected only when Active Storage is configured to use Vips, which was not the default processor in Ra...

Cybersecurity researchers have flagged a maximum-severity security flaw in Ruflo , an open-source agent meta-harness for Anthropic Claude Code and OpenAI Codex, that could result in unauthenticated remote code execution. The vulnerability, tracked as CVE-2026-59726 (CVSS score: 10.0), impacts all versions of the project before version 3.16.3. It has been codenamed RufRoot by Noma Security's research team, Noma Labs. Originally launched as Claude Flow, Ruflo is an AI multi-agent orchestration platform and harness that allows users to deploy multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. The project has more than 66,500 stars on GitHub. The crux of the vulnerability is that Ruflo exposed 233 tools, including shell command execution, database operations, agent management, and memory storage, through an unauthenticated Model Context Protocol (MCP) bridge that's open to the network by default. Specifically, the "docker-comp...

Broadcom has released security updates to address multiple security flaws impacting VMware ESX, vCenter, Workstation, and Fusion, three of which have been designated as critical in severity. The first of the three critical-rated flaws is CVE-2026-59309 (CVSS score: 9.8), which has been described as an authentication bypass in VMware vCenter. "A malicious actor with network access to vCenter may exploit this issue to bypass authentication and gain unauthorized access to the system," Broadcom said. The second critical flaw is a directory-traversal vulnerability in vCenter ( CVE-2026-59310 , CVSS score: 9.8) that a malicious actor with network access can exploit to execute arbitrary code. Both vulnerabilities have been addressed in the versions below - VMware Cloud Foundation, VMware vSphere Foundation versions 9.1.x.x (Fixed in 9.1.0.0300) VMware Cloud Foundation, VMware vSphere Foundation versions 9.0.x.x (Fixed in 9.0.2.0100) VMware vCenter version...
