Let’s begin our journey!

What is Spamming in Cyber Crime?

Spamming simply means sending large numbers of unwanted or irrelevant digital messages to people without their permission.

When used by cyber criminals, it becomes more than a nuisance. It is often linked with:

• Phishing (stealing bank details, UPI passwords, or OTPs).
• Spreading malware (viruses, ransomware).
• Financial frauds (fake loans, investment scams).
• Identity theft (stealing Aadhaar, PAN, or mobile numbers).

For example, A spam SMS saying “Dear SBI customer, your account will be frozen. Click here to update KYC.” The link usually takes you to a fake website designed to steal your bank details.

Types of Spamming in Cyber Crime

Spamming comes in many forms, and cybercriminals constantly innovate new tactics. Below are the major types:

1. Email Spam

• The most common type.
• Examples: Fake bank alerts, lottery scams, “urgent payment” requests.
• Often carries phishing links or infected attachments.

2. Social Media Spam

• Fake accounts, bots, and spammers post malicious links or spread misinformation.
• Example: “Win a free iPhone – click here” posts on Facebook or Instagram.

3. Messaging App Spam

• Scams through WhatsApp, Telegram, or SMS.
• Example: “Your package is waiting, click this link to claim” (phishing attempt).

4. Search Engine Spam

• Hackers inject SEO spam into websites, manipulating search results.
• Example: Fake shopping sites ranking high on Google.

5. Blog & Comment Spam

• Bots leave spam comments with malicious backlinks on blogs and forums.
• Example: “Great article! Check my website for gifts [malicious link].”

Why Spamming is Considered Cyber Crime

Many think spam is just “annoying.” But in reality, it’s much more dangerous:

1. Phishing Attacks – A spam email saying “Update your Paytm KYC”. If you click, you land on a fake page that steals your login and UPI PIN.
2. Malware Distribution – Spam attachments may install ransomware. Many Indian users unknowingly downloaded malware through spam attachments.
3. Financial Fraud – Fake loan offers, Ponzi schemes, or job recruitment scams.
4. Identity Theft – Cyber criminals steal Aadhaar, PAN, and mobile numbers through spam.
5. Disruption of Services – Spam WhatsApp forwards spread misinformation, especially during elections.

Legal Perspective:

• In India, the IT Act 2000 covers spam-related cyber crimes.
• In the US, the CAN-SPAM Act regulates email marketing and imposes fines on violators.
• In Europe, GDPR strengthens rules against unsolicited messages.

Real-Life Examples of Spamming in Cyber Crime

1. KYC Update Scam (2022): Thousands of Indians got an SMS saying their bank account will be frozen without a KYC update. Victims lost lakhs of rupees by entering details on fake websites.
2. Fake Job Offers on WhatsApp: Spam messages promising part-time work-from-home jobs. Victims were asked to pay “registration fees” and then duped.
3. Lottery & Prize Scams: Victims receive spam saying “You have won ₹25 lakh in Kaun Banega Crorepati”. Once they contact, fraudsters demand “processing charges”.

How Spamming Works in Cyber Crime

Cybercriminals use advanced techniques to automate and scale spamming:

1. Botnets

• What it is: A botnet is a network of thousands (sometimes millions) of computers infected with malware.
• Once infected, these computers (called “zombies”) are controlled remotely by cybercriminals without the owner’s knowledge.
• Using botnets, spammers can send millions of emails or messages in just a few hours.

Example: In 2023, CERT-In (Indian Computer Emergency Response Team) warned that many Indian PCs and IoT devices were being hijacked into global botnets. These botnets were then used to send phishing SMS about “KYC updates” and “Loan approvals.”

2. Spoofing

• What it is: Spoofing means forging the “From” address in an email or SMS to make it look like it’s coming from a trusted source.
• Example: An email may appear as support@sbibank.com but actually be support@sbibannk.com (notice the extra “n”).
• SMS spoofing is also common in India. Fraudsters make spam SMS appear as if they are sent from “SBI” or “HDFC” to trick users.

Why it works: Most people don’t carefully check the sender’s ID, so they trust the message and click the malicious link.

3. Data Harvesting

Spammers need huge lists of email addresses or phone numbers. They collect this data through:

• Leaked Databases: Buying stolen Aadhaar, PAN, banking, or mobile records from the dark web.
• Web Scraping: Using bots to scrape emails and phone numbers from websites, forums, and social media.
• Fake Contests/Forms: Creating “free recharge” or “win a prize” forms to collect user details.
• Phishing Attacks: Earlier phishing attempts are used to build bigger spam databases.

For example, in 2022, Delhi Police exposed a racket where cybercriminals bought 1 crore+ Indian mobile numbers from the dark web to run WhatsApp spam campaigns for fake jobs and loan scams.

4. Automation Tools

• Spammers rarely send messages manually. They use bulk mailing software, SMS gateways, and automated bots.
• Popular illegal tools include:
  • Bulk Emailer software – Can send lakhs of emails in one click.
  • SMS Blasters – Distribute spam SMS using VoIP gateways.
  • WhatsApp Bots – Automate sending thousands of WhatsApp messages per hour.
• Some spammers even use AI tools to write personalised spam messages that look human-like, making them harder to detect.

Example: During the pandemic, spam networks used bulk SMS tools to send fraudulent COVID-19 test result messages, asking people to click a link that installed malware on their phones.

5. Hosting & Infrastructure

• To avoid detection, spammers use:
  • Compromised Websites: They hack small Indian business websites and use their servers to send spam emails.
  • Bulletproof Hosting: Hosting services (often outside India) that ignore abuse complaints.
  • Fast-Flux Networks: Constantly changing IP addresses to avoid blacklisting.
• This makes it extremely difficult for authorities to track them.

6. Delivery & Exploitation

Once the spam is sent, the goal is simple:

• Trick users into clicking on malicious links.
• Make victims download infected attachments.
• Convince people to share OTPs, UPI PINs, or Aadhaar details.
• Redirect users to fake websites that look like real banks or e-commerce portals.

If even 1 out of 10,000 people clicks the spam link and falls victim, the spammers can make lakhs of rupees.
