Threat Advisories and Alerts
CISA Publishes Report to Help Protect Schools from Cyberthreats
The recent surge in cyberattacks against the education sector has led the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to release a report addressing the issue. The COVID-19 pandemic made educational institutions increasingly vulnerable to cyberthreats, as virtual learning became widespread and led to the rapid adoption of new and untested technologies. The report titled “Partnering to Safeguard K-12 Organizations from Cybersecurity Threats” provides insight into today’s threat landscape as well as recommendations and resources to protect schools.

The U.K. National Cyber Security Centre (NCSC) has issued an advisory highlighting the tactics and techniques being used by Russia-based threat actor SEABORGIUM and Iran-based group TA453. Attacks linked to these groups in the UK have targeted specific sectors and individuals related to politics, including academia, defense, governmental organizations, non-governmental organizations (NGOs) and think-tanks, as well as politicians, journalists and activists. The advisory aims to raise awareness of this activity and identify the specifics of these actors’ spear-phishing techniques.

ACSC Releases Profile on Royal Ransomware
The Australian Cyber Security Centre (ACSC) has published an advisory profiling Royal Ransomware, which was first seen in September of 2022 and has reportedly been involved in cyberattacks on at least 70 organizations worldwide. The perpetrators behind the attacks are believed to be Russian-speaking cybercriminals. The calling cards of their attacks include callback phishing, the exploitation of unpatched vulnerabilities and double extortion ransomware, which consists of the encryption of victims’ data and threats to sell or publish it if the criminals’ demands are unmet.

New NCSC Report Details Cybersecurity Risks for Charities
A new report released by the U.K. National Cyber Security Centre (NCSC) outlines the potential threats charities face in 2023. Charities are especially vulnerable to attackers as they often have less funds and skilled personnel available for cybersecurity and often operate Bring your own Device (BYOD) policies, raising the risk threshold for security gaps. The report includes case studies that reveal how devastating attacks can be on charities and recommendations to stay protected.
