A new campaign linked to the Mirai malware is exploiting a serious command-injection vulnerability in D-Link DIR-823X routers, identified as CVE-2025-29635. This vulnerability allows attackers to take control of the routers and integrate them into a botnet. Users of these routers are at risk as their devices can be hijacked for malicious purposes, including launching distributed denial-of-service (DDoS) attacks. This situation is particularly concerning since the affected routers are at the end of their life cycle, meaning they are unlikely to receive security updates. It’s crucial for users to be aware of this exploit and take necessary precautions to secure their networks.
Researchers have discovered that malicious Docker images were uploaded to the official 'checkmarx/kics' repository on Docker Hub. Unknown attackers managed to overwrite existing tags such as v2.1.20 and alpine, and they also created a new tag, v2.1.21, which does not match any legitimate release. This poses a significant risk to users who may unknowingly download these compromised images, potentially exposing their systems to vulnerabilities. Companies relying on these Docker images for software development or deployment should take immediate action to ensure their environments are secure. This incident highlights the ongoing challenges in securing software supply chains against malicious actors.
A new malware strain known as Lotus Wiper has been identified targeting the Venezuelan energy sector. This malicious software is designed to disrupt recovery systems by overwriting drives and systematically deleting files, posing a significant threat to the infrastructure of the energy industry. The timing of this attack is particularly notable as it occurred just before a U.S. intervention in Venezuela, raising concerns about the geopolitical implications of cyberattacks in sensitive sectors. Energy companies in Venezuela should be particularly vigilant and assess their cybersecurity measures to protect against such destructive malware. The incident underscores the persistent risk that state-sponsored or politically motivated cyberattacks pose to critical infrastructure.
Researchers have identified a new type of malware known as Lotus Wiper, which has been used in attacks against Venezuela's energy systems. This malware, discovered by Kaspersky, has been particularly destructive, targeting the energy and utilities sector from late last year into early 2026. The attacks utilize two batch scripts to execute the file-wiping functionality, leading to significant data loss and disruption in the affected systems. This incident is concerning as it highlights the vulnerabilities in critical infrastructure, which can have serious implications for national security and public services. With the energy sector being a vital component of any country's operations, such attacks could hinder essential services and impact everyday life.
Researchers have identified a new variant of the LOTUSLITE malware, which is being used to target banks in India and policy circles in South Korea. This malware operates as a backdoor, allowing attackers to communicate with a command-and-control server using dynamic DNS over HTTPS. It offers features like remote shell access, file operations, and session management, indicating its use for espionage purposes. The focus on the banking sector suggests that attackers may be seeking sensitive financial information or operational data. This development raises concerns about the security of financial institutions in India and the potential implications for their clients and operations.
In a significant cyberattack, the Lotus Wiper malware targeted Venezuela's energy sector, causing extensive damage to critical infrastructure. Researchers from Kaspersky reported that attackers first executed batch scripts to disable security measures and prepare the systems for the wiper's deployment. Once the environment was compromised, the wiper erased all data, making recovery impossible. This assault on the energy and utilities sector comes amid rising regional tensions, highlighting vulnerabilities in critical infrastructure. The incident raises concerns about the potential for similar attacks in other regions, emphasizing the need for enhanced cybersecurity measures in vital sectors.
