Spoofing: What is it, how does it work, and how to protect yourself.

Introduction: Spoofing is one of the most common Cyber security threats this digital world faces today.

Spoofing makes attackers pose under the identity of identified parties like commercial banks or even people known to the targeted user to get into their sensitive information. Spoofing crosses texts and phone calls, emails as well as social media, and most of the times it is usually associated with the phishing attack.
This book explains how it works on all these fields, its connection to phishing, and how to protect yourself when one is targeted.

What is Spoofing?

Cyber criminal spoofing is assuming to hold and utilizing the fake credentials of someone by assuming being one legitimate entity or even one authentic figure for manipulating the intended fraud victim. Mostly social engineered techniques will be employed against these spoofs in committing all of those spoofings where major security exposures, stolen data and possible various types of frauds occur.
The spammed form of calls or even email accounts, it starts with an apparent misspelled, wrong figure of name in profile fields.

How Spoofing and Phishing Relate:
Spoofing often leads to phishing. Phishing is a form of cyber attack where attackers use spoofed identities to convince victims to click on malicious links or provide sensitive information. For instance, spoofed mail from a trusted bank may divert the recipient to a malicious website or phishing site for login credentials.
That is to say, spoofing involves masked identity of an attacker; thus, phishing is exploitation for masked information theft.

How Spoofing Works on Different Platforms

1. Telephone Call via SMS

List of some attacks
a- Caller ID Spoofing Since hackers can spoof caller IDS to enable them to call a phone where such a call will appear they call from a trusted organization/individual, they make one disclose sensitive information.

SMS Spoofing: The attacker sends a message which seems to be drafted from a known contact or organization and should send them link that probably lead the victims to phishing sites.

Indicators of Phone Call and SMS Spoofing:
Unexpected calls and messages on familiar numbers with urgent requests.
Suspicious links or asking for sensitive information in any of the messages.

• Demand for PINs, Social Security numbers, or banking information via phone or text.
  

Safety Precautions:

•  Enable two-factor authentication (2FA) on critical accounts.
•  Install Caller ID and Spam Filter Apps such as Truecaller to filter out numbers from suspicious callers.
• Avoid sharing sensitive information via calls or texts without first ensuring that the identity of the requester has been verified.
• Confirm Unsolicited Solicitation by direct telephone to the company and/or individual through information from legitimate sources.
  

What to Do if Spoofed:
Block the number and file a complaint with your phone carrier and the FCC.
Let word go around to all your contacts if someone is using your phone number and unknowingly they respond to some calls or messages.

2. Email Spoofing

They conceal their identities by disguising them as a legitimate sender sending an email that is merely slightly different or even the one of the involved email address. Most spoofed e-mails have phishing links attached or include malware; most importantly, they are being used to extract sensitive information.
Indications of Email Spoofing:

Wrongly spelled or mistyped e-mail addresses-for example, "support@paypa1.com" instead of "support@paypal.com.".

Unsolicited messages often featured urgent messages demanding access to personal or financial details.

Strange links or attachments on the email.

Protect Yourself: Confirm Email Address. Look for spelling or close misspellings. Implement security protocols on your email by using DMARC and SPF. These will ensure that all valid emails going out authenticate your domain.

Beware of Links and Attachments: Never click on any suspicious-looking link or download an attachment without verifying the authenticity of the sender. Educate Employees and Contacts Organizations where the attackers often employ the roles of the executives in Business Email Compromise BEC scams should educate their employees and contacts on spoofed email tactics.

What to do when spoofed: Report this email as spam and flag it to your email provider.

In case of business account spoofing, report to your IT or security team.

Let them know if your email has been hacked.

3. Social Engineering Spoofing

Social media spoofing: Malusers open accounts in social networking sites that may seem actual, like other organizations or legitimate users. The thus accounts deceive the users of divulging personal data by following malicious links or allowing phishing attacks.

Social Media Spoofing: Requests or messages from profiles that look similar to somebody you know but with a slightly different spelling in the username or profile picture. Messages demanding money or confidential data/personal information. Fake posts, comments, or promotions appearing on your profile or in your feed.

Protection Tips:

Make Your Accounts Private : Only a certain percentage of contacts are allowed to see your posts and contacts.

Verify New Contacts: Be cautious about accepting friend requests or messages from profiles that appear unfamiliar or suspicious.

Turn on two-factor authentication on social media to be safe.

Report impersonation accounts directly to the social media network.

What to do if spoofed: Report the profile to the social media site as an impersonation.

Inform your contacts right away that the account is spoofed so they do not open any communications from it.

Review and update security settings to avoid such incidents in the future.

Detection Of Spoofing Attacks If you suspect it's spoofed, then here is what you have to do:
1. Verification through the Source-there's a chance of calling the organization or the individual to confirm if the communication was genuine.
2. Reverse Lookup Tools. To trace the unknown number that was either calling or texting, one can use reverse lookup tools for calls or texts.
3. Check inside Your Logs for Security Any business captures email or log data with possible attempts on Spoofing.

4. Phishing Warnings Most businesses notify their consumers in case of spoofing as well as phishing possibly that is being done present

If You are a Spoofing Victim If you determine spoofing has occurred against you, then the following actions must be taken:

1. Secure Your Accounts Any account you have determined that was used by a spoofer, should have their password changed and two-factor authentication should be turned on.
