🚨 Lazarus APT is Running An Active Campaign

They are using fake meetings to gain full access to corporate systems, credentials, and sensitive data.

• Who is at risk: Fintech, crypto, and high-value environments where macOS is widely used by developers, executives, and decision-makers. 

• Why this is hard to detect: The attack relies on social engineering and native macOS binaries, reducing visibility for traditional EDR tools.
 
• How SOCs should respond: Identify credential exposure early by introducing @anyrun_app’s cross-platform analysis capabilities during triage that offers a 36% higher detection rate.

Hackers Breach Canvas Learning Platform, Exposing Data on Millions of Students and Teachers

A cybersecurity attack on the nation's most widely used classroom software has potentially exposed the personal data of millions of students and educators across the country.

Instructure, the company that runs the Canvas learning management system used by more than 7,000 universities, K-12 districts and education ministries worldwide, disclosed the breach to affected institutions this week.

The company confirmed names, email addresses, student ID numbers and private messages between users had been accessed before the breach was contained.

ShinyHunters warned that a failure to pay could result in the release of "several billions of private messages among students and teachers."

A ransom message on the platform appears to give Infrastructure until May 12 to respond and "negotiate a settlement" before the hackers leak information.
