When it comes to cybersecurity, both hardware and software play crucial roles in keeping your devices safe. Here's a simple breakdown of what each one does and how they work together to protect your information.
Hardware: The Physical Parts
Hardware includes the physical components of a computer, like the processor, hard drives, RAM, and motherboard. These are the parts you can actually touch. In cybersecurity, hardware security involves devices like biometric scanners (such as fingerprint and iris scanners) and Trusted Platform Modules (TPMs), which securely store sensitive information like passwords. Ensuring physical security, such as keeping servers in a locked room, is also important to prevent unauthorised access.
Software: The Programs and Applications
Software consists of the programs and instructions that run on the hardware. This includes operating systems, applications, and stored data. Software security involves tools like firewalls, antivirus programs, encryption software, and intrusion detection systems. These tools help protect against cyber threats like malware, phishing attacks, and ransomware. Regular updates are necessary to keep these tools effective against new and continuously growing threats.
How They Work Together in Cybersecurity
Both hardware and software are essential for a strong cybersecurity defence. Hardware provides a foundation for physical security. For example, biometric scanners verify the identity of users, and TPMs store critical data securely.
Software actively defends against online threats. Firewalls block unauthorised access to networks, antivirus programs detect and remove malicious software, and encryption software protects data by making it unreadable to unauthorised users. Intrusion detection systems monitor network activity and respond to suspicious behaviour.
Building a Strong Cybersecurity Strategy
To create a comprehensive cybersecurity strategy, you need to combine both hardware and software measures. Hardware ensures that your devices are physically secure, while software protects against digital threats. Together, they form a defence system that protects your information from being stolen, damaged, or accessed without permission.
Maintaining both physical and digital security is key. This means regularly updating your software and ensuring the physical safety of your hardware. By doing this, you can build a robust cybersecurity strategy that adapts to new threats and keeps your devices and data safe.
We need to be up to date with the roles of hardware and software in cybersecurity to develop effective strategies to protect against various threats. Both are vital in safeguarding your digital life, providing a layered defence that ensures the security and integrity of your data and systems.
In the hustle and bustle of our daily lives, public Wi-Fi has become a lifeline for many. Whether in coffee shops, airports, or local hangouts, the convenience of free Wi-Fi is undeniable. However, a recent study by NordVPN draws light on a concerning trend – 41% of Brits risk connecting to unsecured public Wi-Fi, despite being aware of the potential cyber threats. Let's break down why this matters and what you can do to protect yourself.
Connecting to public Wi-Fi might seem harmless, but cybercriminals are ingenious opportunists. They can infiltrate your devices and compromise sensitive information. Even on seemingly secure sites, hackers can access your data, deposit malware, and use tactics like ARP spoofing and DNS poisoning. These techniques allow them to pretend to be your device, intercept data, and even lead you to malicious sites without your knowledge.
Recent advancements include malware components using Wi-Fi triangulation to determine your device's real-world location. The purpose of this geolocation remains unclear, but it could potentially be used for intimidation tactics. The good news is that having malware removal and antivirus programs installed can effectively combat infections and safeguard your device.
To combat the risks associated with unsecured public Wi-Fi, consider using Virtual Private Networks (VPNs). These tools act as your cyber bodyguard by encrypting your online identity. This ensures your browsing history is not stored on your device. VPNs establish a secure connection between your device and a remote server, adding an extra layer of protection against potential threats on unsecured networks. They also allow you to hide your IP address and bypass content blocks or firewalls, enhancing both privacy and security. It's akin to sending a sealed letter through the internet. Choose reputable websites with secure connections when entering personal information online.
Understanding the risks is crucial, but taking steps to protect yourself is equally important. Here's a user-friendly guide:
1. Avoid Unsecured Wi-Fi:
When possible, steer clear of unsecured public Wi-Fi. If you must connect, be mindful of the information you access.
2. Use VPNs:
Consider using a VPN to encrypt your online data, safeguarding your privacy while using public Wi-Fi.
3. Keep Software Updated:
Ensure your device has updated antivirus and malware removal tools to detect and prevent potential threats.
4. Stay Informed:
Stay updated on the latest cybersecurity threats and best practices to navigate the digital landscape safely.
Public Wi-Fi is like leaving your front door unlocked; it's convenient, but it invites trouble. Hackers love unsecured Wi-Fi because it's an easy way to grab your sensitive data. By understanding these risks and implementing simple yet effective cybersecurity measures, you can enjoy the benefits of public Wi-Fi without falling victim to cyber threats. Prioritise your online safety and navigate the cyber world with confidence.
Several hospitals in Pennsylvania and California were compelled to close their emergency departments and redirect incoming ambulances due to a recent uptick in cyberattacks, which created a frightening situation. The hack, which targeted the healthcare provider Prospect Medical Holdings, has drawn attention to the fragility of essential infrastructure and sparked worries about how it would affect patient care.
The malware hit Prospect Medical's network, impairing its capacity to deliver crucial medical services. No other option was available to the hospitals that were impacted by the attack other than to temporarily close their emergency rooms and divert ambulance traffic to other hospitals.
The severity of the situation cannot be understated. Hospitals are at the heart of any community's healthcare system, providing life-saving treatments to patients in their most critical moments. With emergency rooms rendered inoperable, the safety of patients and the efficacy of medical response are compromised. Dr. Sarah Miller, a healthcare analyst, voiced her concerns, stating, "This cyberattack has exposed a glaring weakness in our healthcare infrastructure. We need robust cybersecurity measures to ensure patient care is not disrupted."
The impact of the cyberattack extends beyond immediate patient care. It raises questions about data security, patient privacy, and the overall stability of healthcare operations. As patient information becomes vulnerable, there is a risk of data breaches and identity theft, further exacerbating the challenges posed by the attack.
In today’s world, a cybercriminal is capable of stealing data and money with the help of a number of malwares, including keyloggers.
Snake Keylogger is a well-known example of this kind of malware. However, where did Snake Keylogger originate from, how did it operate, and how could you get rid of it? Here is all you need to know about Snake Keylogger.
In order to get an idea of Snake Keylogger, let us first understand what keyloggers are in general.
Keylogger is the kind of malicious program used in logging keystrokes. If your device is infected, the keylogger will record anything you input on the keyboard, including passwords, text messages, payment information, and just about anything else. Essentially, Snake Keylogger is a modular malware program, created by using the .NET developer platform.
With this logging, the malicious operator is able to acquire access over controlling the program, it may as well be able to see what a user is typing into his or her device and even take screenshots, giving them an opportunity to steal a great heap of data.
Discovered in November 2020, it has a history of stealing credentials, clipboard data, and other types of information. Snake Keylogger, a dangerous product that may be purchased on malicious markets like hacking forums, poses a threat to both individuals and companies.
Snake Keylogger usually spreads through phishing campaigns, targeting victims with malicious mail. However, it can also be transmitted via spear phishing, where specific victims are targeted for specific goals. When a Snake Keylogger is sent to a potential victim, it is enclosed in an attachment.
Once received, the user is asked to open a DOCX file. This file may contain a macro (a computer virus), that permits the launch of Snake Keylogger. In case the recipient possesses a version of Microsoft Office with security vulnerabilities, the malware tends to exploit them and infect the device. The same could be intended for PDF readers.
The malware holds the capability of gaining access to recorded data and transferring the same to the attacker, who can exploit it further. The data can either be exploited directly (by hacking bank accounts with stolen credentials) or sell the information to other threat actors in illicit marketplaces, on the dark web.
One of the other reasons why Snake Keyloggers possess threats is their ability to evade antivirus protection, which usually stands as the first line of defense for most devices. In many cases, devices only possess antivirus as their source of protection, thus if Snake Keylogger succeeds in evading the software with no other protection in place, the targeted device could easily and quickly be infected and exploited.
To avoid Snake Keylogger, one can opt for a number of measures:
Discord has gained popularity as a tool for creating communities of interest since the launch of its chat and VoIP services, notably among gamers. Discord can be exploited, though, similar to any other platform that contains user-generated material.
The Chinese Cicada hacking group, known as APT10, was found exploiting security software to deploy a new variant of the LODEINFO malware against Japanese companies.
The victim organizations include media groups, government, and public sector organizations, think tanks, and diplomatic agencies in Japan, all lucrative targets for cyberespionage.
As per Kaspersky analysts who have been keeping tabs on APT10's operations in Japan since 2019, the malicious actors are continuously advancing their exploitation techniques and custom backdoor, 'LODEINFO,' to make it difficult for experts to detect.
Kaspersky published two reports, one showing APT10's exploit chain tactics and the second highlighting the evolution of LODEINFO.
The hunt started in March 2022, Kaspersky found that APT10 cyberattacks in Japan started using a new infection vector, consisting of a spear-phishing mail, a self-extracting (SFX) RAR file, and exploiting a DLL side-loading vulnerability in security software.
The RAR archive consists of the legitimate K7Security Suite Software executable, NRTOLD.exe, and a malicious DLL named K7SysMn1.dll. When NRTOLD.exe is run, it will try to deploy the genuine K7SysMn1.dll file that is usually present in the software suite.
However, the executable will not look for the DLL in a specific folder and therefore permits malware developers to make a malicious DLL using the same name as K7SysMn1.dll.
If the infected DLL is kept in the same folder as the genuine executables, after launching, the executable will deploy the malicious DLL, containing LODEINFO malware.
Because the malware is side-loaded using an authentic security app, other security software may not find it malicious.
The Kaspersky report said:
"K7SysMn1.dll contains a BLOB with an obfuscated routine not observed in past activities. The embedded BLOB is divided into four-byte chunks, and each part is stored in one of the 50 randomly named export functions of the DLL binary. These export functions reconstruct the BLOB in an allocated buffer and then decode the LODEINFO shellcode using a one-byte XOR key."
New LOADINFO
The malware developers launched six new variants of LODEINFO in 2022, the most recent being vo.6.7, launched in September 2022.
APT10's Japan-attacking operations are marked by the expansion of targeted platforms, constant evolution, stealthy infection chains, and better escape.
Other recent unfounded operations related to APT10 consist of a campaign attacking Middle Eastern and African governments via stenography and another exploiting VLC to launch custom backdoors.
