Types, Prevention and Effects of Phishing
Phishing efforts are no longer restricted to emails and are much easier to spot. Malicious communications are nothing new, but they are getting increasingly complex and difficult to distinguish from official business correspondence. Additionally, they are calling, texting, and engaging in talks on social media.
There are steps you can take to protect yourself from phishing attempts, as well as resources that can help. However, a few fast acts with one of these messages can turn into a problem that swiftly spreads across digital channels and devices.
What is Phishing?
Phishing is a malicious practice when fraudsters attempt to obtain users’ data, information, or gadgets. The intention is to have you act quickly and without thinking, and when you do, the phishers may:
- Gaining access to data and information they can use for their own benefit.
- Put malware on your computer.
- Encourage you to divulge your private financial information in order to steal your identity or money.
- To take advantage of others, access your email and send other malicious messages to your contacts.
How a Phishing Attack can be Detected
Before you know the prevention and effects of phishing, you should know how to identify if you are really being phished, and these are the signs:
1. Peril or a feeling of urgency
Negative results-compromising messages should always be viewed with suspicion. Utilizing criticality to request or support early action is another method. Phishers hope that by having the recipient read the email quickly, they will skim the content and miss any abnormalities.
2. Message Format
The use of crude language or a tone of voice in a communication is an immediate indicator of phishing. If, for instance, a friend from business sounds very casual or a close friend speaks in a professional manner, this should raise suspicion. The recipients of the communication should look for any additional information that can point to a phishing message.

3. Strange Requests
If an email requests that you behave in a peculiar way, that could be a sign that it is hazardous. For instance, if an email purporting to be from a specific IT group requests the creation of programming but actually comes from the IT division, which typically handles these tasks halfway, the email is almost definitely fraudulent.
4. Language Mistakes
Spelling errors and grammatical errors are further indicators of phishing texts. The majority of businesses have added spell checking to their email platforms for live communications. Therefore, messages with grammatical or spelling errors should raise red flags since they probably don’t originate from the known source.
5. Different Web Address Types
Another easy way to spot potential phishing attacks is to look for jumbled email addresses, URLs, and domain names. Checking a previous message whose email address matches that of the originator is a great model.
The recipient should continually scan links in emails before clicking them to see what they are meant to do. When an email appears to be from Bank of America yet the email address field is empty of the characters “bankofamerica.com,” it is likely a phishing email.
6. A desire to use personal information for identification, payment, or other purposes
Attackers frequently connect to fake login pages that look real by sending messages that look authentic. The bogus login page contains a login box or a request for ledger details. If the recipient didn’t expect the email, they shouldn’t click the link or enter their login information. As a precaution, recipients should immediately visit the website they believe is the email’s shipper.
After confirming whether you sent that email, if consumers contact inquiring if a message is authentic, provide them the same guidance you do in your own business operations.
- Did the client anticipate receiving the email?
- Does the URL or link lead to the expected or valid website address?
- Does it request that they open an unfamiliar, suspicious document?
- Does it request their user name and password and make threats to remove or disable their access?
You and your partner can establish whether the message is secure by responding to those queries.
How to Prevent Phishing Attacks
Know what you’re working on when conducting regular business with your team, clients, and other consumers in general. Verify the communication’s veracity before acting if you receive a message, call, or email that is unexpected or even just a tiny bit odd. Ask the individual who appears to have the message if they sent it by giving them a call. If the response is “no,” the communication is malicious.
ADDITIONALLY, YOU CAN:
- Enable multi-factor authentication: (MFA) services as you can, including those for your email, should be enabled. Having this additional layer of defense considerably lowers the likelihood that the phishers will gain access to your email or other targeted account if you fall for one of their tactics.
- Update your hardware and software. Patches that defend against the most recent security flaws can be found in the most recent updates for Microsoft Office products, operating systems, third-party apps like Adobe Reader, and smartphone operating systems.
- To reveal the URL of a link in an email, move your mouse over it. Don’t click on anything that seems strange.
- Install contemporary endpoint security programs on your devices. They are frequently offered by popular and well-known security companies like McAfee and Norton. Microsoft also provides endpoint security for Windows and additional programs.
- Always make a backup of your data to ensure that, in the event of an attack, you can resume operations as soon as possible. To make sure your backup procedures are operating as planned, test them periodically.
- Informing your staff about secure computing procedures and how to spot spam and phishing attempts is important. Employee education is crucial because, according to the World Economic Forum, up to 95% of cybersecurity issues can be attributed to human error.
- Examine the attachment’s extension in Microsoft Word. Word documents now finish with.docx because the majority of users have updated their Microsoft products. Question anything with the dated.doc extension.
Be mindful that if you are the target of an assault, you might not be aware of it right away. Instead, your consumers might receive an unexpected message from you as the first sign. Unfortunately, you may only discover you’ve been impacted when a customer calls to confirm something you accidentally sent (but didn’t intend to).

Types of Phishing Situations
The most typical phishing situations are listed below:
1. Email Phishing
Malicious emails sent to people impersonating an actual company are the most typical phishing scenario. This form of attack, also known as spam phishing, enables the cybercriminal to access a sizable number of users who have registered on a website. Thus, phishing emails are frequently distributed in bulk. Since some people from the lot will frequently fall victim, there is a high likelihood of success. Checkout for email signatures to verify if the message is from a trusted source.
2. Clone Phishing
An attacker uses real email messages that a person may have actually received in a clone phishing scenario. The phisher replaces any links or attachments with malicious ones by making a virtual copy, or “clone.”
This is frequently successful because the attacker can argue that the initial message contained a broken link, necessitating the need to send the email again. The recipient wouldn’t consider being suspicious of the sender because the company name would be well-known to them.
As you might expect, clicking on such links would either allow an attacker to install malware on your device or give them access to do so without your knowledge.
3. Domain Spoofing
The third type of email phishing is called domain spoofing, in which the culprit changes the domain name of a reputable company. This trick gives the impression that you are getting an email from a reliable source.
Because email addresses are individual, the phisher can only imitate the company’s address. They achieve this by substituting characters, such as “r” and “n” for “rn” rather than “m.” Otherwise, they use the company name with a separate domain in the hopes that the receiver will only see the local portion of the email address in their inbox.

4. Spear Phishing
This suggests a method where the phisher targets a particular person or group of people rather than a broad user base.
These attacks are successful because they are more tailored to the target. The offender personalizes emails with the recipient’s name, organization, phone number, and other details to give the impression that they are connected in some way to the sender.
5. Whaling
This is a form of spear-phishing where the targets are extremely wealthy People, such as the CEO, who is in charge at the top of the company. With the help of fake emails, the fraudster deceives the executive and gains access to their login information. Since it is difficult to fool such high-ranking officials with a standard phishing attack, hackers frequently replace tax return emails with fake URLs and malicious links that ask for specific information like the target’s name, position, and other personal information that is available on social media platforms.
6. CEO Fraud
This is fraud, as the name implies, committed by an assailant posing as the CEO. The phisher can authorize wire transfers to outside accounts or submit false tax returns on behalf of employees using the CEO’s compromised email account.
The targets in this case are lower-level employees, so if they got an urgent email from the CEO telling them to process a banking transaction or send sensitive information, they would act immediately. Additionally, the scammer might request that staff members install a brand-new program on their computers so that the hacker can spread malware or demand ransom.
CEO fraud is a delicate issue that is said to cost US companies billions of dollars annually.
7. Evil Twin
A malicious WiFi network is the epitome of evil. Crowds of people who want to use fast wireless connections to browse the internet and engage in other online activities frequently visit WI-FI access points.
In this case, the hacker creates a fake version of the WiFi hotspot. Users can listen in on each other’s network traffic after they connect. Both account names and passwords are taken by the attacker. Any attachments that the user accesses while on the infiltrated network are likewise visible to the phisher.
Coffee shops, airports, shopping centers, hospitals, and other public hotspot locations have WI-FI access points that are vulnerable.
8. SMS Phishing (Smishing)
With the introduction of mobile technology, communication and online banking have benefited greatly. At the same time, it provided a fresh entry point for criminals to conduct further offenses. One such instance is smishing, in which online fraudsters use text messages to attract victims to:
- Visit illicit web pages
- Install harmful software
- Call technical support
A smishing effort will more often than not ask you to click on a link that takes you to a website, whether it’s disguised as a coupon code, an offer to win free tickets or free money, or any other kind of offer. Links that force the download of risky software automatically are also quite prevalent. They may have URLs that are familiar to you and seem to come from reliable sources, but their only purpose is to steal your personal data or infect your mobile device with malware.
The practice of requiring you to call customer service for assistance in resolving a problem is less widespread but just as risky. The fraudster will then pose as a legitimate customer support agent to coerce you into giving them personal information. This combines Voice Phishing, a common form of phishing assault on mobile devices.
9. Voice Phishing (Vishing)
Campaigns for phishing are far brasher than those for email or message. The attacker speaks to the victim on the phone and persuades them to divulge personal information rather than hiding behind a virtual screen.
Since the assailant is able to persuade their victims verbally, they frequently dispel any suspicion that it might be a scam. The con artist frequently poses as a representative of your bank, a company executive from the corporate headquarters or another branch, an IRS agent, etc. They will ask for your details for verification under the pretext of a suspicious activity or any other deceit.
Naturally, they use tricks to spoof their phone numbers so that they appear legitimate or reflect your area code. The latter frequently gives targets a false sense of security, causing them to let down their guard.
10. Pharming
As a more sophisticated kind of phishing, pharming is sometimes used instead of more straightforward phishing scams by fraudsters.
Pharming is when someone attacks someone else by installing and running DNS-based custom malware code. The fraudster poisons the DNS cache as part of the attack on the DNS (Domain Name System). Even if consumers enter the right website name, the fraudster can still drive them to the malicious website because this modifies the IP address connected with a website name.
Although less common, attacking the DNS server might jeopardize millions of web users’ URL queries.
11. Watering Holes Phishing
The assault involves a hostile attacker tracking the websites that various targets visit and then attempting to infect those websites with their own malware.
Your computer gets automatically infected with malware when you visit a malicious website that has already been infected with it. This malware then spreads to other systems within the organization. The hacker will frequently observe email usage trends within the company and track websites that employees frequently visit in order to replicate successful watering hole attacks.
Effects of Phishing on Businesses
1. Financial Losses
Financial loss has always been a result of phishing incidents throughout history. The first is the direct loss resulting from money that employees who fell for the hackers’ tricks transferred. The second is the penalties for non-compliance that are enforced by oversight organizations like HIPAA, PCI, and PIPEDA, among others.
These penalties could be extremely high if severe violations of data protection standards occur.
The costs of the investigation into the breach and paying out compensation to the customers who were impacted would also increase the company’s financial losses.
“According to the FBI’s 2018 Internet Crimes Report, Business Email Compromise (BEC) assaults cost US firms more than $1.2 billion”.
2. Intellectual Property Loss
Businesses should be concerned about more than just financial damages in the case of a phishing assault. The loss of client information, trade secrets, project research, and designs is even more tragic.
When a tech, pharmaceutical, or defense corporation is involved, a stolen patent would result in millions of dollars in research costs being lost.
Direct financial losses can be recovered from fairly easily, but losing confidential corporate information is more challenging to replace.

3. A loss of reputation
Businesses frequently make an effort to conceal any phishing attempts they may have experienced. The harm to reputation is the main cause of this. Customers frequently choose to support brands they believe to be dependable and trustworthy. The announcement of a breach will destroy that developed trust in addition to tarnishing the brand’s reputation. It’s difficult to win back customers’ trust, and a brand’s worth is directly correlated with the size of its customer base.
Investor perception of the company will be harmed by a disclosed breach attack. Security online is crucial at every level of a project’s lifecycle. As a result, when a company encounters a data and privacy breach, investor confidence declines.
A successful phishing attack could potentially destroy hundreds of millions in market capitalization by harming both investor and customer confidence.
4. Commercial Disruption
After a phishing attack, especially one involving malicious bugs, it is almost impossible for a business to function exactly as it did before. Malware attacks are typically difficult to recover from. Systems will need to be turned off or shut down, which might significantly reduce productivity.
The economy could suffer severe damage if companies that provide transportation, technology, waste disposal, and other essential infrastructure services were to cease operating.
