SafeBreach Hacker's Playbook Updated for US-CERT Alert (AA20-099A) COVID-19 Exploited by Malicious Cyber Actors


April 9, 2020

SafeBreach Labs has updated the Hacker's Playbook™ with new simulations for attacks described in US-CERT COVID-19 Exploited by Malicious Cyber Actors (AA20-099A) which details the growing use of COVID-19 related attacks by APT groups. Attacks noted are numerous and extensive as unfortunately hackers are leveraging the pandemic to trick users and exploit new remote workforce infrastructure such as networks and VPN access.

The new IOCs defined are predominantly infiltration techniques, socially engineered around coronavirus, using the organizations that are keeping us current and informed, see sample phishing email addressed from World Health Organization that we presented in our Top 4 Security Validations for a Remote Workforce webinar. The phishing lures are designed to direct users to newly registered domains to phish for credentials or download / deploy malware like ransomware or trojans.

The techniques used to exploit employees working from home are designed to leverage VPN, VDI and RDP vulnerabilities and attacks, specifically brute force attacks.

The SafeBreach Hacker’s Playbook addresses the wide array of attacks noted throughout the alert to keep your remote workforce safe.
