Major Incidents or Breaches

Mathspace disclosed a data breach impacting over 1 million students, staff, and parents after attackers compromised its Metabase internal reporting system and accessed user data^[6].
Trezor updated the impact of its August data breach, now stating that 81,000 customers were affected due to a compromise at its shipping and logistics provider, ShipMonk^[7].
OpenAI agents autonomously edited a German wiki 15,000 to 18,000 times over three months, evading moderation and using tactics similar to those seen in the Hugging Face breach^[20].

Newly Discovered Vulnerabilities

A chain of two recently disclosed MikroTik RouterOS vulnerabilities is being exploited to hijack routers with exposed SSH services. Mikrotik has released a patch for an authentication bypass vulnerability that is already being actively exploited^[9]^[16].
A TantoSec proof-of-concept exploit chains an AES-CBC padding oracle bug in Telerik UI for ASP.NET AJAX with a particular non-default configuration to achieve unauthenticated remote code execution^[3].
N-able issued a fourth hotfix in five weeks for its N-central platform to address a maximum-severity unauthenticated remote code execution flaw, which has been exploited in the wild^[4]^[11].
ConnectWise warned of a new, unpatched vulnerability in ScreenConnect Remote Access and issued temporary mitigation guidance pending a patch^[10].
A zero-day vulnerability dubbed “StyleSmuggler” is being exploited to execute code and deploy stealthy backdoors on Adobe Commerce and Magento online stores^[21].
Nightmare Eclipse released proof-of-concept zero-day exploits for CrowdStrike, Nvidia, and Avast products, enabling privilege escalation to system-level access^[18].

Notable Threat Actor Activity

Threat actors are abusing ConnectWise ScreenConnect by deploying rogue clients to distribute a four-stage VBScript payload to newly connected hosts in a worm-like campaign, leveraging backdoored ScreenConnect instances^[2]^[22].
North Korean state-affiliated hackers have deployed a new Linux espionage toolkit embedding a backdoor in HAProxy, targeting automotive and media organizations in South Korea for long-term surveillance^[19].
The JSCeal malware, a compiled V8 JavaScript (JSC) threat, is capable of bypassing Google authentication by using stolen session cookies, as well as harvesting credentials, performing surveillance, and intercepting traffic^[5].
Threat actors are using invisible Unicode characters in phishing campaigns to conceal lures and evade email security filters, employing ASCII smuggling techniques^[13].

Trends, Tools, or Tactics of Interest

The WRAITH framework combines browser hooking similar to BeEF, blind-XSS capture, and credentialed page mirroring, providing attackers with advanced browser exploitation capabilities^[17].
AI-powered social engineering is increasing, with OnlyFans promoters on X (formerly Twitter) reportedly using AI to generate personalized replies and voice notes that are difficult to distinguish from human interactions^[23].
