Key Concepts

• Clickfish Campaign: A global cyberattack campaign.
• Phishing Emails: Deceptive emails designed to trick recipients into revealing sensitive information or downloading malware.
• Malware: Malicious software designed to harm or exploit computer systems.
• Remote Access Trojan (RAT): Malware that allows attackers to control a victim's device remotely.
• Attack as a Service (AaaS): A model where cyberattack tools and services are sold to anyone, regardless of technical expertise.
• Fake Domain Names: Websites created to mimic legitimate ones for fraudulent purposes.
• Two-Layered Verification: A security measure involving multiple checks to confirm the authenticity of information.

Main Topics and Key Points

1. Rise of Online Scams During Peak Travel Season

• Context: The end of the year sees a surge in travel demand.
• Warning: The Vietnam National Administration of Tourism is urging the public to be highly vigilant against online scams.
• Specific Threat: The "Clickfish" global cyberattack campaign is spreading.

2. The Clickfish Campaign: Modus Operandi

• Impersonation: Attackers are impersonating well-known booking platforms such as Booking.com, Agoda, Traveloka, and Airbnb.
• Method: They send phishing emails with familiar subject lines like "Booking Confirmation," "Customer Complaint," "Payment Update," or "Booking Cancellation." These emails are crafted to look identical to legitimate ones.
• Payload Delivery: These emails contain links or Excel files embedded with malware.
• Consequences of Interaction: Clicking on these links or opening the files activates the malware, allowing attackers to:
  • Gain control of the user's device.
  • Steal personal data.
  • Infiltrate internal systems.

3. Impact on the Hospitality Industry

• High Prevalence: Some hotels report that up to 40% of their booking or payment update emails are fraudulent.
• Hotel Experience with Scams:
  • When attempting to call the phone numbers provided in fraudulent emails, no one answers.
  • Much of the information sent in these fake communications is fabricated.
• Hotel Verification Strategy (Two-Layered):
  • Layer 1: Front desk staff are advised to be cautious and meticulously check the authenticity of links, verifying if they truly belong to platforms like Booking.com.
  • Layer 2: After cross-referencing information, if there is any contact from a guest, the hotel will re-contact the guest to double-check the details one more time.
• Alternative Hotel Verification: Some hotels directly contact the entities that booked through them as the most reliable method. They will not proceed if the other party doesn't respond to inquiries about arrival dates and times via online messaging.

4. Technical Details of the Clickfish Malware

• Remote Control: The Clickfish campaign utilizes Remote Access Trojans (RATs).
• Capabilities of RATs:
  • Allow hackers to monitor users.
  • Enable the theft of accounts.
  • Facilitate long-term stealthy presence within a system.

5. The "Attack as a Service" (AaaS) Model

• Worrying Trend: The Clickfish campaign shows signs of operating under an AaaS model.
• Implication: This means that anyone can purchase attack tools without needing advanced technical skills, significantly increasing the risk of cyberattacks.

6. Sophistication of Fake Domains and Links

• Volume of Fake Domains: Cybersecurity experts note that hackers can create hundreds of fake domain names daily.
• Multi-Stage Redirection: When a user clicks on a fraudulent link, they are often led through multiple intermediate steps before reaching the actual phishing website.
• Subtle Deception: Attackers may subtly alter domain names by replacing characters. For example, "booking.com" might be written with a Cyrillic "o" instead of a Latin "o."

7. Security Recommendations for Accommodation Providers

• Technical Measures:
  • Equip staff computers with robust antivirus software.
• Procedural Measures:
  • Increase vigilance.
  • Avoid opening suspicious emails.
  • Do not download attachments from unknown sources.
  • Proactively verify booking information through official channels.
• Vulnerability: The large number of accommodation establishments in Vietnam (tens of thousands) using online booking platforms makes them increasingly vulnerable. This is exacerbated by the fact that many front desk or booking staff lack adequate cybersecurity knowledge.

8. Recommendations for the Public

• Booking Practices:
  • Only book accommodations through reputable platforms.
• Information Protection:
  • Protect payment card information to avoid falling victim to scams.

Key Arguments and Perspectives

• Argument: The increasing reliance on online booking platforms, coupled with a lack of cybersecurity awareness among some staff, creates a significant vulnerability for the hospitality sector.
  • Evidence: The high percentage of fraudulent emails received by hotels and the warning from the Vietnam National Administration of Tourism support this argument.
• Argument: The AaaS model democratizes cybercrime, making sophisticated attacks accessible to a wider range of individuals.
  • Evidence: The mention of the Clickfish campaign exhibiting AaaS characteristics highlights this concern.
• Argument: Subtle manipulation of domain names and multi-stage redirection are common tactics used by scammers to deceive users.
  • Evidence: The expert's explanation of character substitution in domain names and the description of users being led through intermediate steps illustrate this.
