What is Hunters International Ransomware?

Hunters International Ransomware is a financially-motivated ransomware-as-a-service criminal gang that has made headlines in recent months. The group has targeted organizations across various nations including United States, Canada, Europe, Brazil, New Zealand, Japan, and so on. With a global reach and strategic focus on maximizing impact and ransom potential, Hunters International targets a wide range of industries globally. As a result of their non-discriminatory approach, anyone vulnerable can be exploited, including healthcare, automotive, manufacturing, logistics, financial, educational, and food sectors.

Hunters International Ransomware Relation with Hive Ransomware

The Hunters International Ransomware-as-a-Service (RaaS) operation, which originated in late 2023, has drawn attention due to its technical lineage and operational tactics that are similar to those of the notorious Hive ransomware group. In light of previous disruptions by law enforcement agencies of Hive, Hunters International’s rise just after the operation underscores the resilience and adaptability of cybercriminals.

In January 2023, the FBI collaborated with law enforcement agencies in Germany and the Netherlands to successfully dismantle one of the most notorious ransomware groups known as Hive. Since June 2021, the Hive ransomware collective targeted over 1,500 victims worldwide, extracting over $100 million in ransom payments.

In October 2023, security researcher @rivitna2 detected code similarities between Hunters International and Hive ransomware samples. Additionally, @BushidoToken found multiple code overlaps and similarities between the two sets, reporting at least a 60% match. A significant disruption in the security industry led to the initial consensus that Hunters International was a rebranded version of Hive.

Ever since the takedown of Hive ransomware by the FBI, it seems the operators have been busy developing their next project: Hunters International.

Hunters Internation Ransomware Claims Attack On ICBC London and AutoCanada

This recent surge in Hunters International Ransomware can be attributed to the increasing sophistication of cybercriminals and cyberattack on ICBC London and AutoCanada. As organizations across various sectors continue to digitize their operations, vulnerabilities are emerging. Hunters International takes advantage of these gaps, exploiting weaknesses in security protocols.

The Hunters International ransomware group announced a successful breach at ICBC London, resulting in the theft of 6.6 TB of data, or approximately 5.2 million files. While ICBC has not yet confirmed this claim, it was posted on the gang’s leak site. It is currently unknown how much ransom was demanded by Hunters, if any at all, and whether the stolen data includes personal information of customers. The method used to breach ICBC’s network is also still unclear. We have reached out to ICBC London for comment and will update this article accordingly if a response is received.

The group behind this ransomware is known for targeting high-profile companies and government agencies, demanding hefty ransoms. Their methods have evolved rapidly, reflecting a troubling trend in criminal innovation.

According to notification released by AutoCanada, “Immediately upon detecting the incident, AutoCanada took action to safeguard its network and data.  This included engaging with leading cybersecurity experts to assist us with containment and remediation efforts, as well as to conduct a thorough investigation to understand the scope and impact of the incident.”

Additionally, the rise of remote work has expanded attack surfaces. Employees accessing sensitive data from home networks often lack robust defenses against such sophisticated threats. It’s a perfect storm that allows Hunters International ransomware to thrive.

With each incident reported globally, awareness grows about this alarming trend in cybercrime.

How Does Hunters International Ransomware Work?

Hunters International Ransomware operates through a cunning mechanism designed to infiltrate networks quietly. Initially, it uses phishing emails or malicious links to gain access. Once inside, it spreads rapidly across connected systems.

After breaching security protocols, the ransomware begins encrypting files. This process can happen within minutes, locking users out of their data entirely. Victims are left with little recourse but to confront an intimidating ransom note that demands payment in cryptocurrency.

The encryption method employed is typically robust and complex, making recovery without the decryption key nearly impossible. Additionally, some variants may exfiltrate sensitive information before encryption occurs. This tactic heightens pressure on victims by threatening public exposure of their data.

Understanding this attack vector highlights the importance of proactive cybersecurity measures for organizations at risk of encountering Hunters International Ransomware.

The impact extends beyond the immediate loss of access to files. Businesses suffer reputational damage alongside financial losses when operations halt unexpectedly. Data breaches can lead to legal repercussions as well, especially if personal information is compromised.

Employees may experience stress and uncertainty during recovery efforts too. The aftermath of an attack can linger for months or even years, affecting both productivity and morale in affected organizations.

Hunters International Ransomware TTPs

Hunters International Ransomware employs various tactics, techniques, and procedures (TTPs) to infiltrate systems effectively. A common method includes phishing emails that appear legitimate, leading users to malicious links or attachments.

Once inside the network, it often utilizes lateral movement strategies. This allows it to spread quickly across interconnected machines. Attackers may exploit unpatched vulnerabilities as part of their strategy for access.

Encryption plays a significant role in its operation. Once data is encrypted, victims face pressure to pay ransoms for decryption keys. The ransom notes usually contain strict deadlines and threats of data leaks if demands are not met.

Another notable tactic involves targeting backups directly. By compromising backup systems, attackers increase leverage over organizations—making recovery even more challenging without paying the ransom.

These TTPs underline the importance of comprehensive cybersecurity measures in defending against Hunters International Ransomware attacks.

How to Prevent Hunters International Ransomware?

Preventing Hunters International Ransomware starts with robust cybersecurity practices. Regularly updating your software and operating systems is essential. These updates often include critical security patches that can thwart potential attacks.

Utilizing strong, unique passwords for all accounts can significantly reduce risk. Implement multi-factor authentication wherever possible to add an extra layer of protection. Also implement security tools like EDR, SIEM, Firewalls etc. that are most effective in detecting advanced cyber threats.

Educating employees about phishing scams is crucial. Many ransomware infections begin with deceptive emails. Training staff to recognize suspicious links or attachments helps safeguard the entire organization.

Regular backups of important data are vital too. Ensure these backups are stored offline or in a secure cloud environment to prevent them from being compromised during an attack.

Employing advanced threat detection tools can enhance your defenses against Hunters International Ransomware and similar threats, giving you peace of mind as you navigate the digital landscape.

What To Do If You’re a Victim of Hunters International Ransomware?
