- Dropbox reported that attackers exploited a flaw in Lenovo’s email verification process to register fraudulent Lenovo IDs and access Dropbox accounts [20].
- Cybercriminals are selling 153 million digital scans of US and Canadian driver’s licenses on the dark web, likely sourced from a breach at IDScan.net [32].
- Brazilian government and educational institution web servers were compromised by the Gambling Goblin group, who installed malicious Apache modules to hijack traffic and redirect it to betting pages [11].
Newly Discovered Vulnerabilities
- A privilege escalation zero-day vulnerability dubbed FalconFlank has been disclosed in CrowdStrike Falcon [6].
- Seven new security flaws have been added to CISA’s Known Exploited Vulnerabilities catalog, including vulnerabilities being used to deploy reverse shells and crypto miners [7].
- An unauthenticated SQL injection vulnerability (CVE-2026-9586) in Sangoma Switchvox is being actively exploited for remote code execution [16].
- A critical authentication bypass flaw (CVE-2026-82329) in JFrog Artifactory is under active exploitation, enabling attackers to forge admin tokens [18].
- The All-in-One WP Migration and Backup plugin for WordPress contains an SQL injection flaw (CVE-2026-19949) that could allow unauthenticated remote code execution, affecting over 3 million sites [17][33].
- Multiple vulnerabilities in Plex desktop clients and media servers prompted an urgent patch advisory from Plex [14].
- SonicWall SMA 1000 devices are affected by zero-day vulnerabilities enabling unauthenticated remote code execution [23].
- Cisco has issued patches for critical vulnerabilities in IOS XR and Nexus switches that could allow remote code execution and authentication bypass, and has warned of unpatched S/MIME flaws in its secure email products [34].
- Rockwell Automation released patches for over a dozen vulnerabilities across several products, including RSLinx Classic and FactoryTalk [37].
- An exploit has been published for a new Cleo Harmony vulnerability that allows remote authentication bypass via argument bearer manipulation [38].
- Eight security flaws were disclosed across seven command-line AI coding agents, where malicious .git configurations could cause agents like Claude and Codex to execute attacker-controlled code [10].
Notable Threat Actor Activity
- Threat actors are leveraging the Node.js runtime as a malware delivery tool in targeted attacks, abusing its trusted status to deploy malicious payloads [3].
- The Shai-Hulud infostealer worm variant has expanded its credential theft capabilities, now scanning 469 locations across developer and CI/CD environments [4].
- The “Spring Ring” threat group is targeting Microsoft Teams users with vishing attacks aimed at session hijacking, malware distribution, and infrastructure compromise [25].
- The Gambling Goblin group, a Chinese-speaking cybercrime cluster, is responsible for malicious Apache module deployment on Brazilian government web servers [11].
- The “Breeze Comet” threat group is conducting high-impact attacks on Brazilian and global financial systems [21].
- A new Android banking trojan, StreamRat, was distributed to Spanish-speaking users through fake streaming campaigns on Meta ads, enabling near-complete device control [13].
- NSO Group’s Pegasus spyware was used in a zero-click exploit to infect the iPhone of a Serbian student protest movement member [5].
Trends, Tools, or Tactics of Interest
- Recruitment-themed phishing campaigns are using Browser-in-the-Browser (BitB) attacks to steal enterprise credentials [1].
- The Balonx phishing kit uses generative AI to fully automate vishing attacks, including voice calls [2].
- Active malware campaigns are distributing fake software installers that disable Windows Update and weaken Microsoft Defender, targeting users seeking popular software downloads [9].
- Meta ads are being used as a distribution channel for Android malware, such as the StreamRat banking trojan [13].
- Tech support scams are evolving, with scammers using new methods and targeting platforms more intelligently [40][41].
- AI is being leveraged by cybercriminals to accelerate the speed and scale of attacks, providing significant time advantages [24].
- Security tools for AI agents are emerging, such as OpenLeash, which adds human-in-the-loop checks for risky agent actions, and AIR Security’s firewall for AI skills and plugins [31][35].
- Google, Anthropic, and OpenAI have released new cybersecurity-focused AI models, safeguards, and access programs to support defenders [8].
Regulatory or Policy Developments Affecting the Security Industry
- The UK government has introduced late amendments to the Cyber Security and Resilience Bill, granting ministers new powers to block high-risk technology suppliers from critical infrastructure in response to supply chain attack concerns [36].
- California and Colorado will require operating systems to collect users’ ages for compliance, with open-source software like Linux likely exempt [39].
