Several organizations have reported significant cyber incidents. Polymarket experienced a supply chain attack resulting in the theft of $3 million in cryptocurrency. Japanese telecom KDDI disclosed a breach affecting up to 14.22 million email accounts. Tata Electronics, a supplier to major tech firms, suffered a data breach. Brazil's National Civil Defense platform was targeted with a fake alert, and the US National Association of Insurance Commissioners confirmed a data theft via a zero-day vulnerability. Additionally, a new AI-powered phishing service called EvilTokens has been identified, exploiting authentication methods to steal Microsoft 365 tokens.

A recent threat intelligence report has detailed a range of cyber incidents, from supply chain attacks and data breaches affecting major companies to the exploitation of artificial intelligence technologies for malicious purposes. The report highlights the ongoing evolution of cyber threats, emphasizing the need for robust security measures across various sectors.
Polymarket, a cryptocurrency prediction market, confirmed a supply chain attack where a third-party vendor's website was compromised. Malicious JavaScript was injected, leading to fraudulent transactions that resulted in the theft of approximately $3 million from fewer than 15 accounts. The platform's backend systems remained unaffected.
In Japan, telecom operator KDDI reported a breach of its ISP email platform following an intrusion detected on June 17. The incident potentially compromised up to 14.22 million email addresses and passwords associated with services from six internet service providers, including J:COM and Biglobe.
Tata Electronics, an Indian manufacturer of electronics and semiconductors that supplies to companies like Apple and Tesla, experienced a cyberattack and data breach. The company indicated that its IT systems were impacted, while the World Leaks group claimed to have exfiltrated 630GB of data, purportedly including sensitive supplier and customer information.
Brazil's National Civil Defense warning platform, managed by the telecom regulator Anatel, was targeted by a cyberattack that disseminated a false "Extreme Alert" message to mobile devices. The system was taken offline by officials after the fake alert reached users in the regions of Paraná, São Paulo, and Rio de Janeiro.
The National Association of Insurance Commissioners, a US regulatory standards body for insurance, confirmed a cyberattack after the ShinyHunters group claimed to have stolen 3.1 terabytes of data. The group asserted that the breach occurred through an Oracle PeopleSoft zero-day vulnerability and included access to regulatory filings, production logs, and other internal records.
The report also shed light on emerging AI-driven threats. Researchers identified "EvilTokens," an AI-powered phishing service that exploits device-code authentication to steal Microsoft 365 tokens. A significant surge in device-code phishing was observed, with AI-generated lures and automated processes reducing the effort required by attackers.
Another AI-related threat involved a malicious AI skill that hijacked over 26,000 AI agents by leveraging trusted marketplaces and social media advertisements. This supply chain attack initially presented a seemingly benign package, which then used attacker-controlled external instructions to exfiltrate data from agent platforms after user approval.
Furthermore, researchers demonstrated a technique called "BioShocking AI," which tricks agentic browsers into bypassing their security guardrails. Tests conducted on various AI browsers, including ChatGPT Atlas and Perplexity Comet, showed how specially crafted prompts could lead to the exposure of user credentials and sensitive data.
Several vulnerabilities and patches were also highlighted. Cisco addressed CVE-2026-20245, a critical command injection flaw in Catalyst SD-WAN Manager that had been exploited as a zero-day for months. This vulnerability allows an administrator to execute root commands via a crafted file and affects both on-premises and cloud-managed deployments.
Dify released version 1.14.2 to fix four vulnerabilities in its open-source AI platform, including critical flaws CVE-2026-41947 and CVE-2026-41948, which could permit unauthenticated access and cross-tenant data exposure.
Three vulnerabilities in Ubiquiti UniFi OS, identified as CVE-2026-34908, CVE-2026-34909, and CVE-2026-34910, are reportedly being exploited, with observed activity linked to the Mirai botnet. These flaws enable unauthorized modifications, file access, and command execution.
Langflow, an open-source AI workflow tool, is reportedly under attack due to exploitation of CVE-2026-55255, alongside ongoing mass exploitation of CVE-2026-33017. Attackers are enumerating flow IDs to run victim pipelines and extract embedded API keys, with remote code execution capabilities enabling malware deployment and cloud credential theft.
In terms of threat intelligence reports, the "FortiBleed" campaign was uncovered, which transforms compromised FortiGate firewalls into credential-stealing devices across 24 protocols, impacting over 430,000 devices globally and siphoning millions of credentials.
The StockStay espionage malware has been attributed to the Russia-linked Turla group, with targets including Ukrainian government and defense organizations. This malware, disguised as legitimate applications, is delivered through phishing campaigns using malicious remote desktop configuration files.
The Chinese DCloud Uni-App framework has been identified as the foundation for at least 236,493 scam domains since 2022, facilitating fraudulent activities such as fake cryptocurrency exchanges and phishing schemes. Technical indicators suggest centralized, likely China-based, operators are behind this fraud ecosystem.
Finally, the FulcrumSec cloud extortion group has been analyzed for its targeting of cloud-native organizations. This group exploits exposed credentials, unpatched applications, and misconfigured storage, leveraging broad permissions to move laterally, collect data over extended periods, and exfiltrate it using legitimate tools.
A weakness has been identified in Tenda CP3 27.5.57.101. This issue affects some unknown processing of the file Net/NetCheckPing.cpp. This manipulation of the argument interface_name/host causes os command injection. The attack can be initiated remotely.
A security flaw has been discovered in Tenda CP3 27.5.57.101. This vulnerability affects the function SystemAsh of the file Apis/system.c of the component Kylin. The manipulation of the argument AlarmVoiceURL results in os command injection. It is possible to launch the attack remotely.

OpenAI has announced a $1 billion commitment to provide subsidized access to its Daybreak AI cybersecurity tools for under-resourced critical infrastructure defenders. The initiative, named Daybreak for Frontline Defenders, will offer AI models, training, and technical support over the next six months, prioritizing water and wastewater utilities, electric grid operators, and local government entities. This move aims to equip organizations with limited budgets and staff against increasingly sophisticated cyber threats.

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an advisory published on September 5. Sansec, which discovered the flaw and named it StyleSmuggler, said attacks started on September 4. "Sansec is publishing early
In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.

Attackers are exploiting two new PaperCut flaws to steal credentials and gain privileged access in education-sector attacks across the U.S. and Europe. Attackers are exploiting two recelty disclosed PaperCut flaws, CVE-2026-81578 and CVE-2026-82078, in attacks targeting schools and other education organizations in the U.S. and Europe, as reported by TheHackerNews. Arctic Wolf researchers observed
