What are web threats?
Internet-based web threats and cyber security threats expose people and computer systems to harm online. A wide range of threats fit into this category, including well-known threats such as phishing and computer viruses. However, other threats, such as offline data theft, can also be believed to be part of this group.
Web threats and cyber security threats are not confined to online activity but eventually involve the Internet at some stage to cause harm. While not all web threats are created intentionally, many are intended to – or have the potential to cause:
- Denied access:- Prevention of Access to Computer and Network Services.
- Gaining access:- Unauthorized or unwanted access to a private computer and network services.
- Unauthorized or unintended use of computer and network services.
- Disclosing personal data without permission, such as photos, account credentials, and sensitive government information.
- Unauthorized or unwanted changes to the computer and network services.
In recent years, the web threats landscape has grown significantly. Technologies such as smart devices and high-speed mobile networks have allowed for an ever-connected vector of malware, fraud, and other complications. In addition, adopting the web in areas such as communication and productivity through the Internet of Things (IoT) has overtaken consumer security awareness.
As we depend more on the web for everyday life, it will continue to overgrow as an attractive attack option for malicious parties. Convenience and lack of discretion in using the web are among the top concerns that pose new threats to privacy and security.
Although the targets are usually computer-based, human victims ultimately experience the lasting effects of a web threat.
Types of Cyber Security Threats
The threats countered by cyber security are threefold:
- Cybercrime involves single actors or groups attacking for financial gain or disruption.
- A cyber attack often involves gathering politically motivated information.
- Cyberterrorism aims to undermine electronic systems to create fear or panic.
So, how do malicious individuals gain control of computer systems? The most common methods used to compromise cyber security threats are:
Malware means harmful software. Most typical cyber security threats or malware are software created by cybercriminals or hackers to disrupt or damage a legitimate user’s computer. Often spread through unsolicited email attachments or legitimate-looking downloads, cybercriminals can use malware to make money or politically motivated cyberattacks.
Types of Malware
Ransomware is software that encrypts and disables a target’s access to its data until a ransom is paid. As a result, the affected organization is partially or entirely unable to function until it delivers. Still, there is no assurance that payment will result in the required decryption key or that the provided decryption key will work properly.
2. Fileless malware
Fileless malware doesn’t initially install anything. Instead, it changes files native to the operating system, such as PowerShell or WMI. Because the operating system recognizes modified files as legitimate, antivirus software misses a file-less attack; these attacks are stealthy and are ten times more successful than traditional malware attacks.
Spyware gathers data about users’ activities without their knowledge or consent. That may include PINs, passwords, payment information, and unstructured messages.
The usage of spyware is not limited to desktop browsers: it can also work on an essential app or mobile phone.
Adware follows a user’s surfing activity to decide which ads to serve them. Although adware is identical to spyware, it does not install software on the user’s computer or capture keystrokes.
The threat in adware is the erosion of user privacy.
A Trojan hides desirable software or code. Once trustful users downloads, the Trojan can take control of the victim’s system for malicious purposes. Trojans can be hidden in games, apps, or even software patches or embedded in attachments in phishing emails.
Worms target exposures in operating systems to install themselves into networks. They can gain access in several ways: through back doors built into the software, through unintended software vulnerabilities, or flash drives. Once in place, the worm can be used by malicious actors to launch DDoS attacks, steal sensitive data, or launch ransomware attacks.
A virus is a code that injects itself into an application and is executed when the app is run. Once inside a network, a virus can be used to steal sensitive data, launch DDoS attacks or carry out ransomware attacks.
A rootkit is a software that gives malicious actors remote control of a victim’s computer with full administrative privileges. That can inject rootkits into applications, kernels, hypervisors, or firmware. Then, they spread through phishing, malicious attachments, downloads, and compromised shared drives. Rootkits can also be used to conceal different malware, such as keyloggers.
A keylogger is a kind of spyware that observes and monitors user activity. Keyloggers have fair uses. Businesses can use them to watch and monitor employee activity, and families can use them to monitor children’s online behavior.
A bot/botnet is software that performs automated tasks on command. They are used for fair purposes, such as search engine indexing. Still, when used for malicious purposes, they take the form of self-propagating malware rerouted from the central server. It can be connected.
Generally, bots are used in big numbers to form a botnet, a network of bots used to launch a vast remote-controlled flood of attacks, such as DDoS attacks. Botnets can be pretty extensive. For example, the Mirai IoT botnet ranges from 800,000 to 2.5M computers.
11. Mobile Malware
Attacks targeting mobile devices have increased by 50% since last year. Mobile malware threats are just as varied as those targeting desktops, including Trojans, ransomware, ad click fraud, and more. They are spread through phishing and malicious downloads and are a problem for jailbroken phones, which lack these protections that were part of the devices’ original operating systems.
12. Wiper Malware
The wiper is a type of malware with one goal: to erase user data and ensure that this cannot recover it. Wipers take down computer networks in public or private companies in various sectors. Threat actors also use wipers to cover the marks left after an intrusion, which weakens their victim’s ability to respond.
Top Ways to Stay Safe Online
Every year, a large number of users fall victim to cybercrime. According to the Internet Crime Complaint Center, consumers lost more than $1 billion in web-launched scams in 2015. In honor of Safer Internet Day on Feb. 7, Chelsea Groton Bank is highlighting seven tips to help customers stay safe and stay safe from online threats. A safe and secure web environment.
- Keep your computer and mobile devices up to date. The updated security software, web browser, and operating system are the best defense against malware, viruses, and other online threats. Turn on and enable automatic updates so you receive the latest fixes as they become available.
- Set a strong password. A strong password should contain a mix of lower and upper case letters, numbers, and special symbols. And should be a minimum of eight characters long.
- Beware of phishing scams. Phishing scams use fake emails and websites to trick users into revealing login information or private account. Do not click on those links or open any attachments or pop-up screens from sources you are unfamiliar with. Send phishing emails to the Federal Trade Commission and the company, bank, or organization impersonated in the email.
- Keep personal information private. Hackers can use social media accounts to figure out their passwords and answer these security questions in password reset tools. Lock your privacy settings and avoid posting things like birthdays, addresses, mother’s maiden name, etc. Be careful of contact requests from people you don’t know.
- Secure your internet connection. Always password-protect your home wireless network. When connecting to public Wi-Fi networks, be careful about what information you send over it.
- Shop securely. Before shopping online, first, make sure the website uses secure technology. When you’re on the checkout screen, verify that the web address begins with HTTPS. Also, check if a small lock icon appears on the page.
