Kinds of Online Threats
There is no doubt that you need to be vigilant online. As the World Wide Web
evolved over the years, many internet predators have been playing on vulnerabilities
to attack computers and retrieve sensitive data from individuals. Half the time, we
aren’t even aware it is happening until it is too late.
Online threat is deemed any malicious act that attempts to gain access to a
computer network without authorization or permission from the owners. These are
usually done by computer hackers who uses the World Wide Web to facilitate
cybercrime. Web threats use multiple types of malware and fraud, all of which utilize
HTTP or HTTPS protocols, but may also employ other protocols and components,
such as links in email or Instant Messaging apps, or any malware attachments on
servers that access the Web. They benefit cybercriminals by stealing information for
subsequent sale and help absorb infected PCs into botnets. Web threats pose a
broad range of risks, including financial damages, identity theft, loss of confidential
information/data, theft of network resources, damaged brand/personal reputation,
and erosion of consumer confidence in e-commerce and online banking.
The following are the top kinds of online threats that you should be aware of:
 Phishing happens when an email is sent from an internet criminal disguised
as an email from a legitimate, trustworthy source. The message is meant to
lure you into revealing sensitive or confidential information.

 Pharming happens when a hacker (or “pharmer”) directs an internet user to a
fake website instead of a legitimate one. These “spoofed” sites can capture a
victim’s confidential information, including usernames, passwords, and credit
card data, or install malware on their computer. Pharmers usually focus on
websites in the financial sector, including banks, online payment platforms, or
other e-commerce destinations.

 Internet Scam generally refers to someone using internet services or
software to defraud or take advantage of victims, typically for financial gain.
Cybercriminals may contact potential victims through personal or work email
accounts, social networking sites, dating apps, or other methods in attempts
to obtain financial or other valuable personal information. Online scams may
come in various forms such as lottery scam, charity fraud scams, job offer
scams, and online dating scams to name a few.
 Internet robots are also known as spiders, crawlers, and web bots. It is a
software application that is programmed to do certain tasks. Bots are
automated, which means they run according to their instructions without a
human user. Some bots are useful, such as search engine bots that index
content for search or customer service bots that help users. Other bots are
"bad" and are programmed to break into user accounts, scan the web for
contact information for sending spam, or perform other malicious activities. If
it's connected to the Internet, a bot will have an associated IP address.
 Malware or malicious software, is any program or file that is harmful to a
computer user. Here are the most common offenders in the rogues’ gallery of
malware:
Adware (advertising supported software) is unwanted software
designed to throw advertisements up on your screen. Example, pop-up
ads and banner ads.
Spyware is malware that secretly observes the computer user’s
activities without permission and reports it to the software’s author.
Example is a keylogger.
Virus and Worms are malwares that attach to another program and,
when executed—unintentionally by the user—replicates itself by
modifying other computer programs and infecting them with its own bits
of code.
Trojan, or Trojan horse, is one of the most dangerous malware types.
It usually represents itself as something useful in order to trick you.
Once it’s on your system, the attackers behind the Trojan gain
unauthorized access to the affected computer. From there, Trojans can
be used to steal financial information or install threats like viruses and
ransomware.
Ransomware is a form of malware that locks you out of your device
and/or encrypts your files, then forces you to pay a ransom to get them
back.
 Spams are unsolicited emails, instant messages coming from recipients that
are not granted verifiable permission for the message to be sent. Spam
messages can be damaging if you open or respond to it.
 Cyberstalking refers to the use of the internet or other electronic device to
harass or stalk individuals or organizations.
 Cyberbullying refers to the act of tormenting, harassing, or embarrassing
another person using the internet.
 Spoofing happens when someone or something pretends to be something
else to gain our confidence, get access to our systems, steal data, steal
money, or spread malware.
