A Deep Dive into Modern Ransomware Attacks – CryptoMode

/in


In a world where data is valuable, ransomware attacks have become a formidable threat to organizations worldwide. This concern continues to escalate with time, making it imperative for businesses to understand and address it effectively. The recent investigation by Microsoft’s Incident Response team into the relentless BlackByte 2.0 ransomware attacks has underscored these cyber onslaughts’ alarming rapidity and destructive capacity.

The Threatening Velocity of Ransomware Attacks

These cyber adversaries operate with astounding speed. The entire process can be alarmingly wrapped up in five days, from infiltrating systems to inflicting considerable damage. With such agility, these hackers can penetrate systems, encrypt valuable data, and demand a ransom for its release, leaving organizations scrambling to keep up.

In these attacks, the BlackByte ransomware surfaces in the final stage, employing an 8-digit number key to encrypt the data. The dynamics of these attacks underscore the use of a potent mix of tools and techniques, contributing to the high success rates of these malicious endeavors.

The investigation uncovered the troubling practice of exploiting unpatched Microsoft Exchange Servers. This tactic facilitates initial access to the target networks, setting the stage for further malevolent actions.

Blackbyte 2.0: Deceptive Strategies and Sophisticated Tools

Apart from using process hollowing and antivirus evasion techniques to ensure successful encryption, hackers also employ web shells. These allow remote access and control, enabling them to persist within the compromised systems, undetected. Additionally, the deployment of Cobalt Strike beacons furthers their command and control operations, arming them with various skills and making defense efforts more challenging for organizations.

To further avoid detection, cybercriminals cleverly use ‘living-off-the-land’ tools to camouflage their activities as legitimate processes. The BlackByte ransomware also manipulates volume shadow copies on infected machines to obstruct data recovery through system restore points. Specially crafted backdoors are deployed, allowing attackers to maintain access even…

CryptoMode Costly Ransomware Attacks

Ransomware remains one of the biggest problems society faces today. Even global retailers continue to struggle on this front, with nearly half of them suffering from some attack to date. Unfortunately, one in three still pays the ransom to decrypt data as they do not possess proper backups. 

Ransomware Remains A Booming Business

  • These are trialing times for both physical and online retailers.
  • Protecting a business from harm has become much more challenging, especially where ransomware is concerned.
  • Things got out of hand in Sweden this Summer when Coop had to close all shops due to a ransomware attack on Kaseya, an IT company.
  • Moreover, Sophos research confirms nearly half of all retailers have dealt with such an attack in the past year.
  • Making matters worse is how one in three victims decided to pay the ransom to have files decrypted again.
  • Paying is never the answer in situations like these, as there is no guarantee of getting files back. 
  • The average ransom paymentFujitsu Unveils its Blockchain Asset Service for Retailers and Event Organizers in the past year was $147,811, which is absurdly high. 
  • Of the companies paying, less than one in ten effectively got their data back, confirming they must explore other options first.
  • Ransomware attacks can be harmful in other ways, including rising cyber insurance costs and more marketing/PR expenses to rebuild a brand after an attack. 
  • There are several ways to mitigate [most of] the costs associated with such a cyber attack.
  • Unfortunately, those measures require planning and money, something most companies aren’t willing to invest in right now. 
  • Zero Trust-oriented solutions may prove a valuable ally in the fight against ransomware.
  • All devices and users are labeled as threats and only access parts of the network through pre-set access permissions.
  • Both businesses and governments show increased adoption of Zero Trust solutions, mainly in the United States.
  • Even so, ransomware will remain a pressing problem, and investing in more training and contingency plans remains the best option.
