Malware (abbreviated from malicious software) is a generic term for viruses, trojans and other dangerous computer programs used by cybercriminals to severely damage an IT environment or gain access to business-critical data. These programs may propagate via email attachments, website downloads or by exploiting the gaps in your operating system or other software.

Ransomware is a type of malware that threatens to disclose sensitive data or blocks access to files/systems, most of the time by encrypting it until the victim pays a ransom amount within a stipulated deadline. Failure to pay on time can lead to data leaks or permanent data loss. Even if you pay, there’s no guarantee that you will recover your lost data or won’t be exploited in the future.

Insider threats originate from within the targeted business. They could be past workers, suppliers or other business partners who have access to critical business data and computer systems, and they knowingly or unknowingly misuse their access. An insider threat is challenging
to identify since it comes from within the organization.

These attacks are common and easy to implement. When DoS or DDoS attacks happen, hackers flood the targeted system with a high volume of data requests, causing it to slow down, crash or shut down. An abrupt slowdown or unavailability of a website or service is the most evident sign of a DDoS assault.

Credential theft involves the unlawful acquisition of information that an individual or business uses to access websites and sensitive data. Credential theft lets hackers reset passwords, lock the victim’s account, download private data, gain access to other endpoints within the network or even erase sensitive data and backups.

Phishing is a type of social engineering attack in which hackers appear as reliable sources to trick victims into opening phony emails or SMSs so they can penetrate those networks. Business email compromise
(BEC) is a scam where cybercriminals
use compromised or impersonated email accounts to manipulate victims into transferring money or sharing sensitive information.

Cloud jacking, or cloud hijacking, is a type of attack where cybercriminals exploit cloud vulnerabilities to steal the information of an account holder to gain server access.

A MITM attack takes place when an unauthorized entity breaks into a company’s network and behaves as part of the network. It’s a form of eavesdropping in which the attacker intercepts the entire conversation and controls it from the inside. Hackers do this to capture and manipulate sensitive personal information in real-time, such as personal login information, account details and credit card numbers.

A DNS attack is a threat in which the hacker exploits vulnerabilities in the DNS protocol. This is a significant problem in cybersecurity because DNS is a vital component of the IT infrastructure. Hackers often target the servers that host domain names in DNS attacks. In other instances, these attackers will aim to identify flaws in the system and exploit them for their own gain.

Botnets are networks of hijacked, interconnected devices that are manipulated for scams and cyberattacks. A botnet attack is usually conducted by sending spam, stealing data, exploiting sensitive information or launching a vicious DDoS attack.

Hackers use a victim’s computing power to secretly and illegally mine cryptocurrency. Cryptojacking can target individual users, big enterprises and even industrial control systems (ICS). Whatever the method of transmission, cryptojacking code usually operates covertly in the background as unwitting victims use their devices as usual.

This cyberattack aims at stealing classified data from a corporate house or the government for financial, political or competitive advantages. Most cases of cyberespionage are classified as advanced persistent threats (APTs). An APT is a sophisticated cyberattack in which a hacker infiltrates a network without being discovered to acquire critical information over an extended period.

AI and ML help hackers become more efficient in developing an in-depth understanding of how businesses guard against cyberattacks. Using machine learning, hackers can tailor phishing emails to avoid bulk email lists and optimize them to encourage engagement and clicks. To give the interaction the best possible legitimacy, hackers even generate realistic images, social media personas and other content using artificial intelligence.

The adoption of IoT is undoubtedly on the rise. However, due to unregulated data exchange and insufficient legislation, IoT has become a favorite target for cybercriminals. Threat actors’ ability to harm not only the network and software that enable IoT devices, but also the devices themselves, is a significant source of concern regarding the security of IoT devices.

Vulnerabilities within web applications allow hackers to gain direct access to databases to manipulate sensitive data. Business databases are regular targets because they contain sensitive data, including Personally Identifiable Information (PII) and banking details. Common web application attacks include DDoS, SQL injections, path traversal, cross-site scripting and local file inclusion.

An APT is a sustained and sophisticated cyberattack in which a malicious actor gains access to a network and continues undetected for a prolonged duration. Most of the time, it aims at stealing data rather than damaging the IT environment. These persistent attacks are frequently orchestrated by nation-states or criminal cartels.

SQL injection is a code injection technique in which hackers place malicious code in SQL statements. This technique can destroy a database. A successful attack might lead to the illegal access of user lists, the deletion of entire tables and, in some circumstances, the attacker obtaining administrative rights to a database.

Zero-day exploits are cyberattacks aimed at vulnerabilities that a software vendor has not yet fixed or patched. By exploiting such an unpatched vulnerability, these attacks have a significant chance of success and are tough to protect against by using outdated security tools.

Spyware is software that, if installed on your computer, stealthily monitors your online behavior without consent. It can gather information about an individual or business and transfer that data to other parties. You can protect your business from spyware by using defenses like secure email and web gateways, automatic software patch management and regular employee awareness training on security.

Identity theft is a type of fraud in which a cybercriminal creates a fake account/profile like a genuine one in order to carry out scams like money laundering. Synthetic identity theft is a form of identity theft in which scammers combine real and fake information to create a new false identity. Most often, the crimes frequently go unreported or unobserved until the fraudster commits any fraud.

A software vulnerability is a flaw present within software or in an operating system (OS). They can enter your network through various channels, some of which are the fault of the software vendor and others that are the fault of the user. Almost all software will have vulnerabilities in one form or another that must be fixed before cybercriminals rush to exploit them.

A deep fake is a cyberthreat that uses artificial intelligence to manipulate or generate audio/video content that can deceive end users into believing something untrue. To make their messages seem more credible, scammers now leverage AI to create realistic looking user profiles, photographs and phishing emails.

The initial overlaying of 5G technology will be over the existing 4G LTE network. Because of this, there will be vulnerabilities that the new technology will inherit from its predecessor.
