By Modern cybercrime operates across an interconnected web of digital platforms. For example, a threat actor might advertise a new batch of stolen credentials on a hidden dark web forum. He might go on to field inquiries using an encrypted Telegram channel, then handle escrow and final payment through an underground marketplace.
Viewing these individual environments in isolation leads to seeing only fragmented pieces of a much broader threat picture. Likewise, an alert triggered in an isolated chat room can seem minor. It can be perceived as noise unless it is actually correlated with an active listing on a dark web marketplace.
The way today’s cybercriminals work suggests that security teams must look beyond isolated channels. They need to start connecting chat platform chatter with darknet data to build a comprehensive context that uncovers brand targeting, credential drops, emerging fraud schemes, and so much more. Telegram threat intelligence can be the engine that drives the strategy.
The Multichannel Threat Ecosystem
Correlation matters in the era of multichannel threat ecosystems. As a leader in Telegram threat intelligence and investigations, DarkOwl explains that security teams need to evaluate how threat actors move between platforms during an attack cycle.
- Creating Buzz – Threat actors frequently rely on chat channels to generate initial buzz around their plans. Telegram is a fantastic tool for doing so.
- Coordination – With initial buzz generated, Telegram also acts as a coordination platform. Threat actors collaborate with one another and line up customers looking to buy their product.
- Validation and Escrow – When it comes time to validate data dumps and run auction-style access sales, darknet forums serve the purpose. Those same forums are utilized to establish escrow services for payment.
- Monetization – Once access or credential packages change hands, buyers shift to separate networks to monetize what they have purchased. Whatever platform or infrastructure facilitates execution is in play.
- Execution – Execution can take place across a single channel or multiple channels. A buyer can execute a phishing campaign, deploy a ransomware payload, or drain compromised corporate accounts.
The tough part for security teams and SOCs is connecting the dots across all the platforms and channels threat actors utilize. The reality is that today’s cybercriminals have learned how to create a complicated maze that can be extremely difficult to navigate.
The Advantages of Cross-Platform Correlation
The heart of effective correlation is gathering the right data. This is where Telegram threat intelligence proves invaluable. Integrating unified Telegram threat data across both chat networks and traditional dark web forums gives security teams a distinct operational edge. Cross-platform correlation:
- Makes it easier to distinguish real threats from exaggerated chatter.
- Uncovers complex brand and fraud schemes in their earliest stages.
- Facilitates easier tracking of threat actors across platform shutdowns.
- Generates data that can be used to enhance existing threat actor profiles.
- Provides early warning signs of new threats currently in development.
The one thing security teams must always be cognizant of with Telegram investigations is churn. When law enforcement seizes a dark web forum or Telegram bans an illicit channel, threat actors simply migrate. Effective Telegram investigations rely on entity correlation to preserve historical context even as threat actor relocation occurs. That’s why investigators rely so heavily on things like cryptocurrency wallets and PGP keys.
Correlation Unifies Threat Visibility
Siloed intelligence naturally creates security blind spots that are easy for adversaries to exploit. On the other hand, deploying specialized solutions built for Telegram threat intelligence brings the power of correlation to the table. Correlation unifies threat visibility by connecting the dots across all chat channels and dark web platform threat actors utilize in their attacks.
