"Would you go days without washing your hands? Then why ignore cyber hygiene? Here are 5 essential habits to stay safe online!"

🧼 Cyber Hygiene Habits:
1️⃣ Use Strong Passwords – Combine uppercase, lowercase, numbers, and symbols.
2️⃣ Enable Two-Factor Authentication (2FA) – Extra security for logins.
3️⃣ Keep Software Updated – Patches fix security flaws.
4️⃣ Avoid Public Wi-Fi for Banking – Always use a VPN.
5️⃣ Backup Your Data – Ransomware attacks can lock your files forever.

🔐 "Good hygiene keeps you healthy, and cyber hygiene keeps you safe online! Share this with your friends! 🚀"

"Hackers don’t always break into systems—they trick people instead. This is called social engineering!"

💡Examples of social engineering tricks
1️⃣ Fake IT Support Calls – "Sir, we detected a virus on your system. Please share your password!" 🚨
2️⃣ Impersonation Emails – Hackers pretend to be your boss or a colleague, asking for sensitive info.
3️⃣ Free USB Traps – Leaving infected USB drives in parking lots, hoping someone plugs them in.
4️⃣ Fake Websites – Imitating banks or companies to steal login credentials.

🔐 "Always verify before sharing information. Think before you click, and stay safe online!"

"Ever received an email that looks suspicious? You might be dealing with a phishing attack. Let me show you how to spot one!"

💡 examples of phishing emails
1️⃣ Check the sender’s email – If it looks strange or has random numbers, 🚨 red flag!
2️⃣ Look for urgent or threatening language – Scammers pressure you to act fast!
3️⃣ Check the links – Hover over them before clicking. If it’s not from an official website, don’t trust it.
4️⃣ Spelling & Grammar Mistakes – Legit companies proofread their emails!

🔐 "Stay smart, stay safe. If something looks off, don’t click! Share this with your friends to help them stay protected. 🚀"

Spoofing: This is an attack to gain access to a target system through the use of a falsified identity. Spoofing can be used against IP addresses, MAC addresses, usernames, system names, wireless network SSIDs, email addresses, and many other
types of logical identification.

DOS/DDOS: A denial-of-service (DoS) attack is a network resource consumption attack that has the primary goal of preventing legitimate activity on a victimized system. Attacks involving numerous unsuspecting secondary victim
systems are known as distributed denial-of-service (DDoS) attacks. Worms pose a significant risk to network security. They contain the same destructive potential as other malicious code objects with an added twist—they propagate themselves without requiring any human intervention.

on-path attack: In an on-path attack, attackers place themselves between two devices, often between a web browser and a web server, to intercept or modify information that is intended for one or both of the endpoints. On-path attacks are also known as man-in-the-middle (MITM) attacks.

Advanced persistent threat (APT): refers to threats that demonstrate an unusually high level of technical and operational sophistication spanning months or even years. APT attacks are often conducted by highly organized groups of attackers. A, that is inserted into a system, usually covertly, with the intent of compromising the confidentiality, integrity, or availability of the victim’s data, applications, or operating systems or
otherwise annoying or disrupting the victim.

Virus: The computer virus is perhaps the earliest form of malicious code to plague security administrators. As with biological viruses, computer viruses have two main
functions—propagation and destruction. A virus is a self-replicating piece of code that spreads without the consent of a user, but frequently with their assistance—for example, a user must click on a link or open a file.

Trojan: Named after the ancient story of the Trojan
horse, the Trojan is a software program that appears benevolent but carries a malicious, behind-the-scenes payload that has the potential to wreak havoc on a system or network. For example, ransomware often uses a Trojan to infect a target machine and
then uses encryption technology to encrypt documents, spreadsheets, and other files stored on the system with a key known only to the malware creator.

Side-channel: A side-channel attack is a passive, noninvasive attack to observe the operation of a device. Methods
include power monitoring, timing, and fault analysis attacks.

Insider threats: are threats that arise from individuals who are trusted by the organization. These could be disgruntled
employees or employees involved in espionage. Insider threats are not always willing participants. A trusted user who
falls victim to a scam could be an unwilling insider threat.

Ransomware: Malware used to facilitate
a ransom attack. Ransomware attacks often use cryptography to “lock” the files on an affected computer and
require the payment of a ransom fee in return for the “unlock” code.

That response shows the URL you're pinging, the IP address associated with that URL, and the size of the packets being sent on the first line. The next four lines show the replies from each individual packet, including the time (in milliseconds) it took for the response and the time-to-live (TTL) of the packet, which is the amount of time that must pass before the packet is discarded.
