Types of Cyber Threats

Malware:

A subtype of software called malware is intended to harm computers, networks, and other devices, frequently by data theft or causing harm to systems.

Malware is harmful software that can enter a system through email attachments, corrupted downloads, compromised sites, or physical objects like USBs. Stealing data, harming the system, or opening a gateway for attackers, can harm the system.

Phishing:

Phishing is a practice whereby sensitive data, including usernames, passwords, and financial information, are fraudulently obtained through spoofed emails or texts. Through emails or communications that seem to be from reliable sources, phishing is a method of social engineering assault that deceives individuals into disclosing their sensitive data.

Ransomware:

One form of malicious software, known as ransomware, encrypts a user's data & then demands cash in exchange for the key to unlock it. Phishing emails and system exploits are also common ways for ransomware to propagate. When engaged, it locks down the victim's information with encryption and asks for a ransom to unlock it.

Distributed denial of service attacks

To render a website or network inaccessible to its intended audience, hackers may employ a technique known as DDoS (Distributed Denial of Service) assaults. DDoS attacks are launched via botnets as well as other ways to overwhelm a server to the point where it becomes unreachable to legitimate users.

Insider Threats:

Negligence, malice, or compulsion can all contribute to the development of a potentially dangerous insider threat.
People who have legitimate access to a network or system can pose a threat if they decide to exploit that access for malicious purposes.

Advanced Persistent Threats:

APTs, short for "advanced persistent threat," are advanced attacks that sneak up on their targets over time and steal valuable information or intellectual property. Attackers with advanced capabilities and a clear understanding of their intended victims carry out APTs, which often involve a series of attacks designed to accomplish a single aim.

Social engineering

The term "social engineering" refers to the practice of using psychological manipulation tactics to coerce others into divulging private information or taking potentially dangerous activities.
Pretexting, baiting, & quid pro quo strategies are just a few examples of social engineering techniques used to deceive targets into disclosing private information.

Zero-day exploits:

When software has a flaw that can be targeted by attackers before the fix or patch is available, we call this a zero-day exploit. Software flaws known as zero-day exploits are especially perilous because attackers can take advantage of them before a patch or remedy is made available by the manufacturer.
