From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
  • In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there was no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. * The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware.

Ransomware Hit $1 Billion in 2023
Ransomware Hit $1 Billion in 2023
In 2023, ransomware actors intensified their operations, targeting high-profile institutions and critical infrastructure, including hospitals, schools, and government agencies. Major ransomware supply chain attacks were carried out exploiting the ubiquitous file transfer software MOVEit, impacting companies ranging from the BBC to British Airways. As a result of these attacks and others, ransomware gangs reached an unprecedented milestone, surpassing $1 billion in extorted cryptocurrency payments from victims. Last year’s developments highlight the evolving nature of this cyber threat and its increasing impact on global institutions and security at large.

Ransomware Cases Increased Greatly in 2023
Ransomware Cases Increased Greatly in 2023
As we move further into 2024, we must be cautious (maybe even fearful!) of ransomware cases increasing even more than in previous years. Though governments around the world are taking more interest in the worldwide threat, we can see from the increase of cases that our actions have not been enough to thwart the ransomware threat. As new groups continue to form, former groups continue to evolve into new brands, and the big players continue to ramp up their efforts, we must remain vigilant and focus on our preparation and early detection capabilities.

The ticking time bomb of Microsoft Exchange Server 2013
I monitor (in an amateur, clueless way) ransomware groups in my spare time, to see what intelligence can be gained from looking at victim orgs and what went wrong. Basically, I’m a giant big dork with too much free time. I’ve discovered two organisations with ransomware incidents, where the entry point appears to have been Exchange Server 2013 with Outlook Web Access enabled, where all available security updates were applied.

2023’s ransomware rookies are a remix of Conti and other classics
Ransomware’s business model is a big part of what’s made it such a potent threat for so many years. However, we dug into multi-point ransomware attacks from 2023, and found another factor in ransomware’s staying power: a seemingly endless supply of new cyber crime groups starting ransomware operations.
