ZLoader Malware Returns With DNS Tunneling to Stealthily Mask C2 Comms

ZLoader Malware Returns With DNS Tunneling to Stealthily Mask C2 Comms

Dec 11, 2024 Ransomware / Malware
Cybersecurity researchers have discovered a new version of the ZLoader malware that employs a Domain Name System (DNS) tunnel for command-and-control (C2) communications, indicating that the threat actors are continuing to refine the tool after resurfacing a year ago. "Zloader 2.9.4.0 adds notable improvements including a custom DNS tunnel protocol for C2 communications and an interactive shell that supports more than a dozen commands, which may be valuable for ransomware attacks," Zscaler ThreatLabz said in a Tuesday report. "These modifications provide additional layers of resilience against detection and mitigation." ZLoader , also referred to as Terdot, DELoader, or Silent Night, is a malware loader that's equipped with the ability to deploy next-stage payloads. Malware campaigns distributing the malware were observed for the first time in almost two years in September 2023 after its infrastructure was taken down. In addition to incorporating various...
Black Basta Ransomware Evolves with Email Bombing, QR Codes, and Social Engineering

Black Basta Ransomware Evolves with Email Bombing, QR Codes, and Social Engineering

Dec 09, 2024 Threat Intelligence / Malware
The threat actors linked to the Black Basta ransomware have been observed switching up their social engineering tactics , distributing a different set of payloads such as Zbot and DarkGate since early October 2024. "Users within the target environment will be email bombed by the threat actor, which is often achieved by signing up the user's email to numerous mailing lists simultaneously," Rapid7 said . "After the email bomb, the threat actor will reach out to the impacted users." As observed back in August, the attackers make initial contact with prospective targets on Microsoft Teams, pretending to be support personnel or IT staff of the organization. In some instances, they have also been observed impersonating IT staff members within the targeted organization. Users who end up interacting with the threat actors are urged to install legitimate remote access software such as AnyDesk, ScreenConnect, TeamViewer, and Microsoft's Quick Assist. The Window...
Navigating the Future: Key IT Vulnerability Management Trends

Navigating the Future: Key IT Vulnerability Management Trends 

Feb 11, 2025Vulnerability / Threat Detection
As the cybersecurity landscape continues to evolve, proactive vulnerability management has become a critical priority for managed service providers (MSPs) and IT teams. Recent trends indicate that organizations increasingly prioritize more frequent IT security vulnerability assessments to identify and address potential security flaws. Staying informed on these trends can help MSPs and IT teams remain one step ahead of potential cyber-risks. The Kaseya Cybersecurity Survey Report 2024 navigates this new frontier of cyber challenges. The data is clear: Organizations are becoming increasingly reliant on vulnerability assessments and plan to prioritize these investments in 2025. Companies are increasing the frequency of vulnerability assessments  In 2024, 24% of respondents said they conduct vulnerability assessments more than four times per year, up from 15% in 2023. This shift highlights a growing recognition of the need for continuous monitoring and quick response to emerging t...
Black Basta Ransomware Gang Actively Infiltrating U.S. Companies with Qakbot Malware

Black Basta Ransomware Gang Actively Infiltrating U.S. Companies with Qakbot Malware

Nov 24, 2022
Companies based in the U.S. have been at the receiving end of an "aggressive" Qakbot malware campaign that leads to Black Basta ransomware infections on compromised networks. "In this latest campaign, the Black Basta ransomware gang is using QakBot malware to create an initial point of entry and move laterally within an organization's network," Cybereason researchers Joakim Kandefelt and Danielle Frankel  said  in a report shared with The Hacker News. Black Basta, which emerged in April 2022, follows the tried-and-tested approach of double extortion to steal sensitive data from targeted companies and use it as a leverage to extort cryptocurrency payments by threatening to release the stolen information. This is not the first time the ransomware crew has been observed using Qakbot (aka QBot, QuackBot, or Pinkslipbot). Last month, Trend Micro  disclosed  similar attacks that entailed the use of Qakbot to deliver the  Brute Ratel C4  framework, which, in ...
