Russian Hacktivists Disrupt Dutch Institutions with DDoS Attacks

 

Several Dutch public and private organizations have experienced significant service outages this week following a wave of distributed denial-of-service (DDoS) attacks linked to pro-Russian hacktivists. The Netherlands’ National Cyber Security Center (NCSC), part of the Ministry of Justice, confirmed that the attacks affected multiple sectors and regions across the country.  

The NCSC disclosed that both government and private entities were targeted in what it described as large-scale cyber disruptions. While the full scope is still being assessed, municipalities and provinces including Groningen, Noord-Holland, Drenthe, Overijssel, Zeeland, Noord-Brabant, and cities like Nijmegen, Apeldoorn, Breda, and Tilburg reported that public portals were intermittently inaccessible. 

A pro-Russian threat group calling itself NoName057(16) has claimed responsibility for the cyberattacks through its Telegram channel. Though the NCSC did not confirm the motive, the group posted that the attacks were a response to the Netherlands’ recent €6 billion military aid commitment to Ukraine, as well as future support amounting to €3.5 billion expected in 2026. Despite the widespread disruptions, authorities have stated that no internal systems or sensitive data were compromised. 

The issue appears confined to access-related outages caused by overwhelming traffic directed at the affected servers — a hallmark of DDoS tactics. NoName057(16) has been a known actor in the European cybersecurity landscape since early 2022. It has targeted various Western governments and institutions, often in retaliation for political or military actions perceived as anti-Russian. The group also operates DDoSIA, a decentralized platform where users can participate in attacks in exchange for cryptocurrency payments. 

This model has enabled them to recruit thousands of volunteers and sustain persistent campaigns against European targets. While law enforcement in Spain arrested three alleged DDoSIA participants last year and confiscated their devices, key figures behind the platform remain unidentified and at large. The lack of major indictments has allowed the group to continue its operations relatively unimpeded. 

The NCSC has urged organizations to remain vigilant and maintain strong cybersecurity protocols to withstand potential follow-up attacks. With geopolitical tensions remaining high, experts warn that such politically motivated cyber operations are likely to increase in frequency and sophistication. 

As of now, restoration efforts are ongoing, and the government continues to monitor the digital landscape for further signs of coordinated threats.

Android TV DDOS Attacks malware Vo1d

Malware Attack on Android TV Devices Affects Over 1.6 Million Users

 



Cybersecurity researchers have discovered a new form of malware that is spreading through Android TV devices across the globe. This malware, known as Vo1d, has already infected over 1.6 million devices, turning them into remote-controlled bots used for illegal activities without the owners’ knowledge.  

The Vo1d malware has existed for a while, but researchers at XLab recently identified a stronger, more advanced version that makes it harder to detect and remove. This upgraded variant has been designed to avoid being analyzed or controlled by cybersecurity experts, making it a serious concern for Android TV users.  


How the Vo1d Malware Works  

Once Vo1d malware enters an Android TV device, it secretly connects it to a network controlled by hackers, known as a botnet. This allows the attackers to control thousands of devices at once without the owners realizing it. These devices are then used to carry out illegal activities like DDoS attacks and ad click fraud.  

In a DDoS (Distributed Denial of Service) attack, a large number of devices flood a website or service with so many requests that it crashes, making it inaccessible. On the other hand, ad click fraud involves the infected devices automatically clicking on online ads, creating fake revenue for dishonest advertisers. Both of these activities can cause financial losses to companies and harm online platforms.  

The malware has been particularly active in countries like Argentina, Brazil, China, Indonesia, South Africa, and Thailand. However, since it is spreading rapidly, users in other countries should also remain cautious.  


Why This Malware Is Difficult to Detect  

One of the main challenges with the new Vo1d variant is that it uses advanced encryption methods, which prevent cybersecurity professionals from studying or controlling it. It also hides deep within the device’s system, making it nearly impossible for regular antivirus software to detect and remove it.  

This ability to stay hidden allows the malware to operate silently for long periods, allowing hackers to keep using the device for illegal purposes. As a result, users may remain unaware that their device has been compromised.  


How to Protect Your Android TV Device  

To reduce the chances of your Android TV being infected by Vo1d, consider following these precautionary steps:  

1. Buy From Trusted Sources: Always purchase Android TV devices from well-known brands or official retailers. Avoid buying from unknown sellers, as some devices may already be compromised before purchase.  

2. Update Regularly: Install all firmware and security updates provided by the device manufacturer. These updates often fix vulnerabilities that malware exploits.  

3. Download Apps Carefully: Only download apps from official platforms like the Google Play Store. Avoid installing apps from third-party websites, as they may carry hidden malware.  

4. Watch for Unusual Activity: If your Android TV starts slowing down, overheating, or using too much data without reason, it may be infected. In such cases, reset your device and consider installing a trusted antivirus app.  

5. Secure Your Network: Make sure your home Wi-Fi has a strong password and activate firewall settings to reduce the chances of remote attacks.    


The rapid spread of Vo1d malware has raised concern among cybersecurity experts. With over 1.6 million devices already infected, users need to stay alert and take protective measures. By purchasing devices from verified sources, keeping software updated, and avoiding untrusted apps, users can reduce their risk of falling victim to such malware attacks.  

Staying informed about new threats and remaining cautious with device usage is the best way to keep your Android TV safe from harmful malware like Vo1d.

Russian Telecom Company "Beeline" Hit, Users Face Internet Outage

Russian Telecom Company "Beeline" Hit, Users Face Internet Outage

Internet outage in, telecom provider attacked

Users in Russia faced an internet outage in a targeted DDoS attack on Russian telecom company Beeline. This is the second major attack on the Moscow-based company in recent weeks; the provider has over 44 million subscribers.

After several user complaints and reports from outage-tracking services, Beeline confirmed the attack to local media.

According to Record Media, internet monitoring service Downdetector’s data suggests “most Beeline users in Russia faced difficulties accessing the company’s mobile app, while some also reported website outages, notification failures and internet disruptions.” 

Impact on Beeline

Beeline informed about the attack on its Telegram channel, stressing that the hacker did not gain unauthorized access to consumer data. Currently, the internet provider is restoring all impacted systems and improving its cybersecurity policies to avoid future attacks. Mobile services are active, but users have cited issues using a few online services and account management features.

Rise of threat in Russia

The targeted attack on Beeline is part of a wider trend of cyberattacks in Russia; in September 2024, VTB, Russia’s second-largest bank, faced similar issues due to an attack on its infrastructure. 

These attacks highlight the rising threats posed by cyberattacks cherry-picking critical infrastructures in Russia and worldwide.

Experts have been warning about the rise in intensity and advanced techniques of such cyberattacks, damaging not only critical businesses but also essential industries that support millions of Russian citizens. 

Telecom companies in Russia targeted

How Beeline responds to the attack and recovers will be closely observed by both the telecom industry and regulators. The Beeline incident is similar to the attack on Russian telecom giant Megafon, another large-scale DDoS attack happened earlier this year. 

According to a cybersecurity source reported by Forbes Russia, the Beeline attack in February and the Megafon incident in January are the top hacktivist cyberattacks aiming at telecom sectors in 2025. 

According to the conversation with Forbes, the source said, “Both attacks were multi-vector and large-scale. The volume of malicious traffic was identical, but MegaFon faced an attack from 3,300 IP addresses, while Beeline was targeted via 1,600, resulting in a higher load per IP address.”

Cyber Crime Data Breach DDOS Attacks IoT Password

Huge Data Leak Puts 2.7 Billion Records at Risk – What You Should Know

 



A security issue has surfaced involving an unprotected database linked to Mars Hydro, a Chinese company known for making smart devices like LED grow lights and hydroponic equipment. Security researcher Jeremiah Fowler discovered this database was left open without a password, exposing nearly 2.7 billion records.


What Data Was Leaked?  

The database contained sensitive details, including WiFi network names, passwords, IP addresses, and device identifiers. Although no personal identity information (PII) was reportedly included, the exposure of network details still presents serious security risks. Users should be aware that cybercriminals could misuse this information to compromise their networks.


Why Is This Dangerous?  

Many smart devices rely on internet connectivity and are often controlled through mobile apps. This breach could allow hackers to infiltrate users’ home networks, monitor activity, or launch cyberattacks. Experts warn that leaked details could be exploited for man-in-the-middle (MITM) attacks, where hackers intercept communication between devices. 

Even though there’s no confirmation that cybercriminals accessed this database, IoT security remains a growing concern. Previous reports suggest that 57% of IoT devices have critical security weaknesses, and 98% of data shared by these devices is unencrypted, making them prime targets for hackers.


Rising IoT Security Threats  

Cybercriminals often target IoT devices, and botnet attacks have increased by 500% in recent years. Once a hacker gains access to a vulnerable device, they can spread malware, launch large-scale Distributed Denial-of-Service (DDoS) attacks, or infiltrate critical systems. If WiFi credentials from this breach fall into the wrong hands, attackers could take control of entire networks.


How Can Users Protect Themselves?  

To reduce risks from this security lapse, users should take the following steps:

1. Update Device Passwords: Many IoT gadgets use default passwords that are the same across multiple devices. Changing these to unique, strong passwords is essential.

2. Keep Software Up-to-Date: Manufacturers release software patches to fix security flaws. Installing these updates regularly reduces the risk of exploitation.

3. Monitor Network Activity: Watch for unusual activity on your network. Separating IoT devices from personal computers and smartphones can add an extra layer of security.

4. Enhance Security Measures: Using encryption tools, firewalls, and network segmentation can help defend against cyberattacks. Consider investing in comprehensive security solutions for added protection.


This massive data leak stresses the importance of IoT security. Smart devices provide convenience, but users must stay proactive in securing them. Understanding potential risks and taking preventive measures can help safeguard personal information and prevent cyber threats.

Understanding VoIP DDoS Attacks: Prevention and Mitigation Strategies

 


A distributed denial-of-service (DDoS) attack targets a VoIP server by overwhelming it with phony user requests. This excessive traffic can exceed the network’s capacity, causing service disruptions and making genuine user requests unprocessable. Online criminals exploit these attacks to disrupt Voice Over Internet Protocol (VoIP) network services, the backbone of modern business phone systems and customer service software. VoIP services are particularly susceptible to DDoS attacks, as even a failed attempt can significantly degrade voice call quality and reliability. 
  
Modus Operandi of VoIP DDoS Attacks 
 
DDoS attacks aim to overwhelm a network with fake traffic, resulting in service denial for legitimate users. A typical VoIP server managing hundreds of calls per hour might struggle to respond to thousands of requests per second during an attack. Key attack methods include:
  • Botnets: Hackers deploy large networks of compromised devices, such as PCs, routers, mobile phones, and IoT devices, to generate attack traffic.
  • SIP Flood Attack: The attacker sends numerous Session Initiation Protocol (SIP) call requests, crashing the victim's VoIP server.
  • SIP Reflection Attack: Hackers spoof the victim's IP address and send queries to random servers, which flood the victim’s server with responses, overloading it.
Mitigation Tips to Defend Against VoIP DDoS Attacks 
 
Adopting robust defense mechanisms can help protect VoIP systems from DDoS attacks. Key strategies include: 
  
1. Use a Reverse Proxy A reverse proxy acts as an intermediary between clients and servers, handling and filtering requests to shield the server. Benefits include:
  • Regulating inbound traffic to ensure only legitimate requests pass through.
  • Disguising the origin server's IP address to prevent direct targeting by hackers.
  • Minimizing latency by offloading tasks such as encrypting and decrypting TLS/SSL communications.
2. Real-Time Network Monitoring Real-time monitoring tools establish a baseline of regular activity to detect anomalies. These tools:
  • Identify unusual network behavior, enabling rapid responses to DDoS-induced traffic spikes.
  • Protect endpoint protocols and IP blocks from malicious requests.
  • Help prevent VoIP fraud by detecting and mitigating suspicious activities.
3. Implement Rate Limiting Rate limiting reduces the impact of malicious bot traffic by controlling the volume of requests. It works by:
  • Delaying or blocking excessive requests from a single IP or multiple sources.
  • Setting thresholds to limit the frequency of actions within a specific time frame.
  • Ensuring only legitimate traffic reaches critical resources.
Rate limiting effectively curtails attackers' ability to sustain a successful DDoS attack. 

VoIP DDoS attacks pose significant risks to modern communication systems, but proactive measures can mitigate these threats. By using reverse proxies, adopting real-time monitoring tools, and implementing rate-limiting techniques, organizations can safeguard their VoIP infrastructure against malicious traffic and ensure uninterrupted services.

Understanding and Preventing Botnet Attacks: A Comprehensive Guide

 


Botnet attacks exploit a command-and-control model, enabling hackers to control infected devices, often referred to as "zombie bots," remotely. The strength of such an attack depends on the number of devices compromised by the hacker’s malware, making botnets a potent tool for large-scale cyberattacks.

Any device connected to the internet is at risk of becoming part of a botnet, especially if it lacks regular antivirus updates. According to CSO Online, botnets represent one of the most significant and rapidly growing cybersecurity threats. In the first half of 2022 alone, researchers detected 67 million botnet connections originating from over 600,000 unique IP addresses.

Botnet attacks typically involve compromising everyday devices like smartphones, smart thermostats, and webcams, giving attackers access to thousands of devices without the owners' knowledge. Once compromised, these devices can be used to launch spam campaigns, steal sensitive data, or execute Distributed Denial of Service (DDoS) attacks. The infamous Mirai botnet attack in October 2016 demonstrated the devastating potential of botnets, temporarily taking down major websites such as Twitter, CNN, Reddit, and Netflix by exploiting vulnerabilities in IoT devices.

The Lifecycle of a Botnet

Botnets are created through a structured process that typically involves five key steps:

  1. Infection: Malware spreads through phishing emails, infected downloads, or exploiting software vulnerabilities.
  2. Connection: Compromised devices connect to a command-and-control (C&C) server, allowing the botmaster to issue instructions.
  3. Assignment: Bots are tasked with specific activities like sending spam or launching DDoS attacks.
  4. Execution: Bots operate collectively to maximize the impact of their tasks.
  5. Reporting: Bots send updates back to the C&C server about their activities and outcomes.

These steps allow cybercriminals to exploit botnets for coordinated and anonymous attacks, making them a significant threat to individuals and organizations alike.

Signs of a Compromised Device

Recognizing a compromised device is crucial. Look out for the following warning signs:

  • Lagging or overheating when the device is not in use.
  • Unexpected spikes in internet usage.
  • Unfamiliar or abnormal software behavior.

If you suspect an infection, run a malware scan immediately and consider resetting the device to factory settings for a fresh start.

How to Protect Against Botnet Attacks

Safeguarding against botnets doesn’t require extensive technical expertise. Here are practical measures to enhance your cybersecurity:

Secure Your Home Network

  • Set strong, unique passwords and change default router settings after installation.
  • Enable WPA3 encryption and hide your network’s SSID.

Protect IoT Devices

  • Choose products from companies that offer regular security updates.
  • Disable unnecessary features like remote access and replace default passwords.

Account Security

  • Create strong passwords using a password manager to manage credentials securely.
  • Enable multi-factor authentication (MFA) for an added layer of security.

Stay Updated

  • Keep all software and firmware updated to patch vulnerabilities.
  • Enable automatic updates whenever possible.

Be Wary of Phishing

  • Verify communications directly with the source before providing sensitive information.
  • Avoid clicking on links or downloading attachments from untrusted sources.

Use Antivirus Software

  • Install reputable antivirus programs like Norton, McAfee, or free options like Avast.

Turn Off Devices When Not in Use

  • Disconnect smart devices like TVs, printers, and home assistants to minimize risks.

Organizations can mitigate botnet risks by deploying advanced endpoint protection, strengthening corporate cybersecurity systems, and staying vigilant against evolving threats. Implementing robust security measures ensures that businesses remain resilient against increasingly sophisticated botnet-driven cyberattacks.

Botnet attacks pose a serious threat to both individual and organizational cybersecurity. By adopting proactive and practical measures, users can significantly reduce the risk of becoming victims and contribute to a safer digital environment.

Cyber Security DDoS DDOS Attacks Free VPN IP Address Network Security Privacy Risks Proxy Service

Free VPN Big Mama Raises Security Concerns Amid Cybercrime Links

 

Big Mama VPN, a free virtual private network app, is drawing scrutiny for its involvement in both legitimate and questionable online activities. The app, popular among Android users with over a million downloads, provides a free VPN service while also enabling users to sell access to their home internet connections. This service is marketed as a residential proxy, allowing buyers to use real IP addresses for activities ranging from ad verification to scraping pricing data. However, cybersecurity experts warn of significant risks tied to this dual functionality. 

Teenagers have recently gained attention for using Big Mama VPN to cheat in the virtual reality game Gorilla Tag. By side-loading the app onto Meta’s Oculus headsets, players exploit location delays to gain an unfair advantage. While this usage might seem relatively harmless, the real issue lies in how Big Mama’s residential proxy network operates. Researchers have linked the app to cybercrime forums where it is heavily promoted for use in activities such as distributed denial-of-service (DDoS) attacks, phishing campaigns, and botnets. Cybersecurity firm Trend Micro discovered that Meta VR headsets are among the most popular devices using Big Mama VPN, alongside Samsung and Xiaomi devices. 

They also identified a vulnerability in the VPN’s system, which could have allowed proxy users to access local networks. Big Mama reportedly addressed and fixed this flaw within a week of it being flagged. However, the larger problem persists: using Big Mama exposes users to significant privacy risks. When users download the VPN, they implicitly consent to having their internet connection routed for other users. This is outlined in the app’s terms and conditions, but many users fail to fully understand the implications. Through its proxy marketplace, Big Mama sells access to tens of thousands of IP addresses worldwide, accepting payments exclusively in cryptocurrency. 

Cybersecurity researchers at firms like Orange Cyberdefense and Kela have linked this marketplace to illicit activities, with over 1,000 posts about Big Mama appearing on cybercrime forums. Big Mama’s ambiguous ownership further complicates matters. While the company is registered in Romania, it previously listed an address in Wyoming. Its representative, using the alias Alex A, claims the company does not advertise on forums and logs user activity to cooperate with law enforcement. Despite these assurances, the app has been repeatedly flagged for its potential role in cyberattacks, including an incident reported by Cisco Talos. 

Free VPNs like Big Mama often come with hidden costs, sacrificing user privacy and security for financial viability. By selling access to residential proxies, Big Mama has opened doors for cybercriminals to exploit unsuspecting users’ internet connections. This serves as a cautionary tale about the dangers of free services in the digital age. Users are advised to exercise extreme caution when downloading apps, especially from unofficial sources, and to consider the potential trade-offs involved in using free VPN services.

Juniper Networks Warns of Mirai Malware Threat to Routers with Default Passwords

 

Juniper Networks has issued a warning about a vulnerability in its Session Smart Routers, emphasizing the risk of Mirai malware infection if factory-set passwords are not changed.

Starting December 11, the company began receiving reports from customers about "suspicious behavior" on their devices. Upon investigation, Juniper identified a common factor: users had not updated the default login credentials.

A specific variant of the Mirai malware has been scanning for these routers, exploiting the unchanged passwords to infiltrate systems. Once infected, the devices were reportedly "subsequently used as a DDoS attack source" to bombard websites with excessive traffic. However, Juniper did not disclose the number of devices affected or the locations of the attacks.

According to Juniper, Mirai is capable of executing "a wide range of malicious activities" beyond DDoS attacks. Past cases have revealed its involvement in spreading cryptominers and enabling "click fraud" schemes that manipulate online advertising metrics.

To safeguard their devices, Juniper advises Session Smart Router users to implement strong, unique passwords immediately and to stay vigilant for unusual network activity. Signs to monitor include unexpected port scans, increased login attempts, and surges in outbound traffic.

"If a system is found to be infected, the only certain way of stopping the threat is by reimaging the system as it cannot be determined exactly what might have been changed or obtained from the device," the advisory states.

Juniper also notes that Mirai commonly targets connected devices like routers and cameras, often exploiting software vulnerabilities to spread. Using default credentials further simplifies the intrusion process, making it crucial to update them
