Excerpt: “While they soon reproduced the exploits, modified them for further capabilities, and discovered a new document preview vector, the researchers did not disclose details for fear other threat actors would abuse it. Unfortunately, threat actors have been able to reproduce the exploit on their own from information, and malicious document samples posted online and have begun sharing detailed guides and information on hacking forums. Starting on Thursday, threat actors began sharing public information about the HTML component of the exploit and how to create the malicious document. On Friday, more instructions were posted on generating the payload and a CAB file that included the path traversal vulnerability component.”

A macro virus has been attached to this email, and if the recipient accepts to download the file, the virus will infect the target’s computer, causing it to crash and freeze. Using the social media feature of spear-phishing to target specific individuals, the attackers exploited the technique as a natural extension of standard spear phishing techniques.”

Title: Ransomware Lessons for a Nation Held Hostage
Date Published: September 12, 2021

https://www.lawfareblog.com/ransomware-lessons-nation-held-hostage

Excerpt: “Instead, anti-ransomware policy should focus on punishing the perpetrators. Some existing hostage recovery policies crack down on perpetrators directly through specialized units designed to disrupt hostage-taking attacks. In the United States, this looks like the FBI’s Hostage Rescue Team and two military Special Forces units—the Army’s Delta Force and the Navy’s SEALs—which relentlessly train to disrupt hostage crises around the world. In Colombia, specialized units in both the police and army focus exclusively on hostage-taking; they have been credited with driving the dramatic reduction in Colombian kidnapping over the past 20 years.”
