Is Medusa evil or good? In this case, definitely evil. Medusa botnet has made a comeback acquiring a range of skills from featuring ransomware capabilities to now being recognized as a DDoSMaaS. Attackers are increasingly using Microsoft OneNote to deliver a variety of malware. QBot banking trojan has joined one such league of threats. Now, cybercriminals can embed almost any file type when creating malicious OneNote documents, such as LNK or VBS attachments.

Ukraine faces a new cyber threat in the form of info-stealing malware dubbed Graphiron. Nodaria, an APT linked to the WhisperGate wiper attacks, is supposedly behind this operation. Nodaria was mostly unheard of before the Russian invasion of Ukraine.

Top Vulnerabilities Reported in the Last 24 Hours

Toyota blurts out sensitive data

US-based researcher Eaton Zveare discovered a bug in Toyota's GSPIMS web portal that gave him access to private data.

The portal contained a function that would allow users to generate a JSON Web Token based on the provided email address.

Flawed Gartner Peer Insights widget

A DOM XSS flaw was discovered in the Gartner Peer Insights widget that is believed to have existed since the software's inception. When the widget was available, several websites were vulnerable to DOM-based cross-site scripting (XSS). This is a client-side attack taking place within a browser window. Proof-of-Concept (PoC) code, exploit test pages, and a YouTube video demonstrating the bug have been made public.

**ICS bugs in Siemens ALM **

Industrial cybersecurity firm Otorio laid bare two critical flaws in the Siemens Automation License Manager (ALM) that could be combined to compromise industrial control systems.
