![](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png)The recent actions of hackers underline the need to be more proactive with cybersecurity. The Kimsuky cybercrime group has been using advanced malware, known as RandomQuery, to gather intelligence and extract sensitive information. This serves as a stern reminder of the increasing threat of ransomware attacks in 2023.

 

**The Rising Danger of Kimsuky's Cyberattacks**

The Kimsuky group has consistently utilized custom malware in its reconnaissance campaigns. Its primary objective is to lay the groundwork for more damaging attacks down the line. The group recently deployed a variant of RandomQuery, designed to search out files and siphon sensitive data.

These hackers are not aimlessly casting a wide net. Instead, their attacks are focused on organizations supporting human rights activists and defectors. In the past, they've used malware like FlowerPower and AppleSeed, and RandomQuery is the latest tool in their arsenal.

**Gathering Data Through Spear Phishing**

The first wave comes in the form of spear phishing, highly targeted attacks involving innocent-looking emails. These hackers disguise their emails to look like they are from Daily NK, a well-known news website from Seoul that reports on North Korea issues. If you accidentally open the file attached to these emails, it starts a Visual Basic script. This program reaches out to a remote server and fetches the second part of the harmful RandomQuery malware.

**The Latest Threat: ReconShark**

Alongside RandomQuery, the Kimsuky hackers have created another tool, ReconShark. This tool collects data from your computers, allowing for more accurate attacks. ReconShark is a newer version of Kimsuky’s earlier tool, BabyShark. It helps the group avoid security systems and take advantage of system weaknesses.

The group's latest phishing attack is very clever, making it hard to realize it's an attack. The emails use the names of experts, tricking recipients into thinking the emails are legitimate. In certain instances, they have even used Microsoft OneDrive to host malicious documents.

**Protecting Your Business: A Proactive Stance**

Given this evolving threat landscape, what can you do to protect your business? Start by raising awareness within your organization about these threats. Educate your staff about distinct types of ransomware and malware and the telltale signs of a phishing email.  
 Implement strong cybersecurity measures, including antivirus software, firewalls, and secure backup solutions. Regularly update your systems and software to patch security vulnerabilities. And should your business fall victim to an attack, consult with a cybersecurity expert to minimize damage and prevent future attacks.

The Kimsuky hackers should serve as a sign for you to reinforce your cybersecurity efforts and protect your business from these escalating threats. You've worked hard to build your business – don't let hackers dismantle it.
