Weekly Security Sprint EP 134. Cyber Resilience, Critical Infrastructure attacks, Alphabet soup, and offboarding concerns
In this week's Security Sprint, Dave and Andy covered the following topics:
Warm Open:
- Critical infrastructure sectors on the most concerning threats – and needed solutions. “With critical infrastructure constantly under myriad threats, sector-focused information sharing and analysis centers and organizations collect, analyze and disseminate actionable cyber and physical threat information to stakeholders and provide them with tools to mitigate risks and enhance resiliency. To mark Cybersecurity Awareness Month, Threat Beat asked: 1) What is the most pressing short-term security concern in your sector? 2) What is one thing the public and/or industry/government can do now to address this?” Responses include DNG-ISAC, E-ISAC, FB-ISAO, Food and Ag-ISAC, Health-ISAC, MS-ISAC, ONE-ISAC, Space ISAC, and WaterISAC.
Main Topics:
Canadian Centre for Cyber Security: Alert - AL25-016 Internet-accessible industrial control systems (ICS) abused by hacktivists. In recent weeks, the Cyber Centre and the Royal Canadian Mounted Police have received multiple reports of incidents involving internet-accessible ICS. One incident affected a water facility, tampering with water pressure values and resulting in degraded service for its community. Another involved a Canadian oil and gas company, where an Automated Tank Gauge (ATG) was manipulated, triggering false alarms. A third one involved a grain drying silo on a Canadian farm, where temperature and humidity levels were manipulated, resulting in potentially unsafe conditions if not caught on time.
