Protecting your connected device from the Blink Botnet malware is an important task. Starting in May 2019, Blink botnet malware has been targeting more than a million Internet of Things (IoT) devices to make it temporarily unusable or deny service. The attack uses a technique called he DDoS (Distributed Denial of Service). By exploiting vulnerabilities in routers, video recorders and smart cameras, hackers can gain access to these devices and use them to congest networks with malicious traffic. This effectively disrupts internet services on the affected networks.
To protect your device from the Blink botnet malware, there are several steps users should take:
- Acknowledge that all connected devices are at risk and be aware of any security threats that could target your specific devices.
- It is essential to install patches as soon as they are released by device manufacturers; as this significantly reduces the risk of vulnerability exploitation.
- Software updates should be installed regularly as this provides essential protection against maliciously modified content which may contain exploits that could potentially infect your device with the Blink botnet malware.
What is the Blink Botnet Malware?
Safety experts are now warning users to be on the lookout for the latest strain of botnet malware called Blink.

The Blink botnet malware is a sophisticated strain of malicious software designed to conduct distributed denial-of-service (DDoS) attacks on targeted computers and networks. It uses a hybrid approach that consists of a custom payload delivered by a modular HTTP backdoor.
Once deployed on the infected computer, the Blink backend bot builds an infection footprint and starts waiting for commands from its operators. It attempts to detect if antivirus or other security products are running, as it looks for system vulnerabilities that it can leverage to spread more quickly within the compromised environment.
The payload carries various malicious components, such as executable libraries and DLLs, plugins, miners, browser hijackers and bots. As each command is received from the client server the payload runs different tasks according to the instructions (such as mining Monero cryptocurrency without user’s consent).
Commands are also sent for data exfiltration, including names of users with administrator privileges and passwords and private encryption keys. In addition there are also download & execute capabilities with which malicious code can be installed in encrypted executables or document files which get deployed when required or upon users’ actions.
The Blink botnet malware begins communications with its command-and-control servers via encrypted web requests made through port 80 of intentional firewall bypasses system architecture weaknesses to complete its objective successfully.
How Can You Protect Your Devices from the Blink Botnet Malware?
The Blink botnet malware has recently spread among several network devices, leaving many at risk of data theft, malware infection, and even system shutdowns. Because of this, everyone needs to take steps to protect their devices from this new threat. This article will discuss how you can protect your devices from the Blink botnet malware and stay safe online.
Use a Secure Router
A secure router is one of the best steps to protect your devices from the Blink Botnet malware. Your router is responsible for converting your internet activity into something your computers and other connected devices can understand. Without the proper security configuration, it will be vulnerable to attack.
To help ensure that your router is as secure as possible, ensure it has the latest firmware installed and a good firewall. Unfortunately, configuring a good firewall requires some technical knowledge and is beyond the scope of this article. However, many online guides provide step-by-step instructions on how to set up a secure router with a strong firewall.
You should also choose a router that supports advanced security protocols such as WPA2-PSK (Wi-Fi Protected Access). This particular protocol increases wireless encryption strength and provides better protection from intruders who try to gain access to your network by exploiting wireless connections or unauthorised users accessing personal information on your network. WPA2-PSK also comes with features such as 802.1X authentication, MAC address filtering, and SSID broadcasting that further increase the security level of your network connection.
Installing antivirus software or an intrusion prevention system (IPS) in your computer(s) can also help in making sure that all incoming data is scanned for malicious code before being allowed through into your system or device(s). In addition, some IPS systems have additional layers of protection such as allowing only connections from known sources while blocking any suspicious incoming traffic to protect you from likely cyber threats, including malware attacks like those launched by botnets like Blink Botnet malware.
Install Security Software
The best way to protect your devices from the Blink Botnet malware is to install and regularly update comprehensive security software from a reputable provider. Security measures such as antivirus, antispyware, firewall protection, and intrusion detection should be configured to protect your devices from malicious threats. Having these security tools up-to-date will help proactively block threats before they can gain access or cause any damage to your systems. In addition, regular scans for malicious activity and malware should be performed on all of your devices connected to the internet. You should also practise good cyber hygiene such as protecting your passwords and never leaving devices unattended.
Change Default Passwords
One of the best advice for protecting yourself from the Blink botnet malware is to always change the default passwords on all your devices, especially those connected to the internet. This advice applies to devices like routers, digital video recorders (DVRs) and IP cameras. Many of these devices come with a pre-set password easily guessed by hackers. Changing the password to something more secure will act as a first line of defence against malware like Blink.
Another tip for increasing security against nefarious actors is to keep all your devices up-to-date with the latest firmware and risk patches regularly issued by the manufacturer. A regular practice will result in fewer potential vulnerabilities that attackers or botnets can leverage in attacks against your network or individual devices.
If you want additional protection, use a firewall or utilise an Intrusion Prevention System (IPS) between your network and modem to scan incoming traffic before allowing it onto your network. A reputable Anti-Virus software can also help detect malicious files while blocking some malicious URLs. However, remember they’re not infallible and should be used as part of a larger security strategy.
Keep Your Systems Updated
System patching and updating is one of the best ways to protect your devices and systems from the Blink Botnet malware. Software updates can fix known vulnerabilities, keeping them from becoming an entryway for malware like Blink Botnet. In addition, the developers of applications and hardware operate on a timeline of releasing patches to fix any issues that arise. Therefore, as soon as a vulnerability is identified and patched, it is important to ensure that all systems are updated accordingly. Many types of software will update automatically, but it is a good practice to check regularly and ensure that updates are complete. Additionally, the operating system should be closely monitored for updates as the developer releases them; many systems support automatic backups alongside their patching process so this should not require much attention on your part.
It is also important to recognize which types of software may pose a greater risk than others regarding security threats. Browsers, for example, are easy targets for malicious actors since browsers offer numerous extensions as an added feature — often from unverified sources — that can contain vulnerable code which can be leveraged by hackers seeking to exploit these vulnerabilities via malware such as Blink Botnet.
Therefore, keep your systems up-to-date with their necessary patches and avoid installing software from unknown sources or running executables from emails. In addition, you should help protect your system from infections like the Blink Botnet virus.
Conclusion
In summary, protecting your devices from the Blink Botnet malware is an important responsibility. To safeguard your devices, you should update your software regularly, use strong passwords and avoid downloading unknown files. Additionally, you can protect yourself by using a reliable antivirus program and taking extra precautions by monitoring network traffic to detect malicious activity. These simple steps will ensure that your devices are not vulnerable to the Blink Botnet malware and any other malicious programs that may be trying to gain access to them.
