Phishing as a Supply Chain Attack is a Tangible Threat to Businesses

In the case of phishing supply chain threats, large companies aren’t the only ones in charge — every business should be concerned. The complex network of supplier relationships has turned into a target market for cybercriminals. Let’s go into why phishing targeting supply chains, what are the tactics, case studies & how you can protect your business.

Why Phishing Attacks Target Supply Chains

Supply chain relationships are interrelated and depend on reciprocal faith. The ties between these key players are exploited by cybercriminals and used as their attack vectors:

• Vendors and Suppliers: They frequently have the ability to access sensitive data and systems.
• Communication: The continued weekly email traffic makes it easier for a phishing email to go unnoticed.
• Complex Networks: More points of entry added additional avenues for penetration.

The aim? To penetrate one company and exploit its access to attack others in the chain, causing a ripple effect.

Tactics employed in these attacks

Phishing supply chain tactics are clever the ways cybercriminals use them. Here are some of them:

1. Vendor-Targeted Phishing

• Impersonating a legitimate supplier.
• Sending fake invoices that contain malware attachments.
• Asking to update payment information to redirect money.

2. Email Scams

• Phishing emails that look like they’re coming from a trusted contact.
• The ystema (pronounced heysem) uses email spoofing to impersonate real email domains.
• Sending messages with a sense of urgency or threat to encourage hasty decisions.

3. Compromised Accounts

• Harvest connections to grow their network.
• Use of verified accounts to legitimize the scam.
• Persist in the network to search for more vulnerabilities
