Telegram Phishing: The New Hotspot for Scammers

In the constantly evolving landscape of cybercrime, threat actors are quick to adapt and exploit platforms that offer speed, anonymity, and broad reach.

While email and SMS remain staples, instant messaging platforms have increasingly become fertile ground for malicious activities.

Over the past few years, Telegram, known for its encrypted messaging and channel functionality, has seen a significant surge in its use by phishers and scammers, fundamentally altering how these fraudulent operations are organized and executed.

From secure chat to cybercrime hub

Telegram's core features - end-to-end encryption, secret chats, large-scale channels, and anonymous bot functionality - were designed to prioritize user privacy and communication freedom.

Ironically, these same features provide an ideal operational environment for threat actors.

Facilitating the phishing lifecycle

Telegram is now being leveraged across the entire spectrum of phishing and scam campaigns:

1. Command and Control (C2)

Large, private Telegram channels and groups serve as marketplaces and communication hubs for cybercriminals.

Here, actors buy, sell, and trade stolen credentials, phishing kits, exploit tools, and access to compromised systems. This infrastructure allows for rapid communication and coordination among distributed criminal groups, making it difficult for law enforcement to monitor or dismantle these operations.

2. The rise of Phishing-as-a-Service (PhaaS)

The platform is a major incubator for Phishing-as-a-Service (PhaaS) offerings.

Scammers can easily purchase full-service kits, including pre-built phishing pages, automated message bots, and scripts designed to harvest credentials from victims. This dramatically lowers the barrier to entry for novice criminals.

3. Delivery mechanism for scams

Beyond merely organizing scams, Telegram is increasingly used as the direct delivery vehicle.

Scammers utilize the platform to:

• Impersonate Support Staff: Setting up fake customer service accounts for major banks, crypto exchanges, or tech companies, then luring victims with urgent support requests.
• Cryptocurrency Scams: Running elaborate investment schemes, fake initial coin offerings (ICOs), and "pump-and-dump" groups, often targeting individuals interested in the volatile crypto market.
• Malware Distribution: Using bots and file-sharing capabilities to distribute malicious files disguised as legitimate software updates, documents, or apps.

Key tactics exploited by scammers on Telegram

Example: The “Booking.com side job” scam

A concrete example is the “Booking.com side job” scam that spreads via Telegram.

You’re contacted out of nowhere with an offer to do simple remote tasks for a “hotel booking platform” like optimising reservations or reviews. The pay sounds great for just an hour of work a day, and you’re quickly moved into a group chat with a “mentor” and fake participants posting screenshots of big daily earnings.

To start, you’re told to register on a professional-looking site that uses Booking-style branding and then “recharge” your account, usually via crypto, so it has a positive balance. After a few dummy “booking tasks”, your dashboard shows rising commissions and often even allows a small withdrawal, which convinces many people it’s legit.

Once you’re hooked, the trap closes.

Suddenly, your account shows a negative balance or “locked” commissions. Support insists you must deposit more to fix it, unlock profits, pay fees or taxes, and each payment only unlocks a new invented condition.

In the end, there is no job, no partnership with Booking.com.

Just a fake platform designed to keep you paying into it until you give up.

Defending against Telegram-based threats

While Telegram's security features are robust for legitimate users, the environment necessitates vigilance.

Organizations and individuals must implement layered defenses:

• User Education: Continuous training on spotting social engineering tactics, especially those relying on urgency or high financial returns. Verify the identity of any account contacting you, even if it appears official.
• Official Verification: Always navigate directly to official websites or apps rather than clicking links provided in a chat, and check for official verification badges where applicable.

The shift of malicious activity onto Telegram highlights a critical challenge: As communication technology advances, the methods of those seeking to exploit it advance too.

The platform's utility for privacy makes it a double-edged sword that will likely remain central to cybercrime operations for the foreseeable future.

FAQ

Why has Telegram become so popular with scammers?

The same features that protect legitimate users — end-to-end encryption, secret chats, large-scale channels, and anonymous bots — also give criminals an ideal operating environment. Private channels serve as marketplaces for stolen credentials and phishing kits, and the anonymity makes operations hard for law enforcement to monitor or dismantle.

What is Phishing-as-a-Service (PhaaS) on Telegram?

PhaaS offerings are full-service scam kits sold through Telegram channels: pre-built phishing pages, automated message bots, and credential-harvesting scripts. They dramatically lower the barrier to entry, letting novice criminals run professional-looking campaigns.

How does the “Booking.com side job” scam work?

Victims receive an unsolicited offer for simple, well-paid remote tasks, get moved into a group chat with a “mentor” and fake participants, and are told to register on a Booking-style site and “recharge” the account with crypto. Early small withdrawals build trust — then the account shows a negative balance or locked commissions, and every new payment only unlocks another invented fee. There is no job and no Booking.com partnership.

How can I verify whether a Telegram account is legitimate?

Never rely on the chat itself: navigate directly to the official website or app instead of clicking links in messages, check for verification badges where they exist, and independently verify the identity of any account that contacts you — especially when the message leans on urgency or promises high returns.

Can organizations train employees against messenger-based phishing?

Yes. revel8 supports Telegram in its simulated phishing scenarios, so teams can safely experience messenger-based scams such as fraudulent job offers or credential-theft attempts, alongside voice, SMS and deepfake channels — with immediate micro-training when someone falls for a simulation.
