Hackers Fake Brands with PDFs Globally
Hackers fake brands like Microsoft and DocuSign with PDFs in phishing campaigns. These attacks surged between May and June 2025. For example, they trick users into calling threat-controlled numbers. This threat undermines online trust worldwide.
How the Attack Works
Phishing emails include PDFs with fake brand logos. They embed QR codes or links to scam pages. Additionally, they urge victims to call for help. Consequently, attackers steal sensitive data or install malware.
Targeting and Tactics
The campaigns impersonate Adobe, PayPal, and more. They use TOAD to create urgency with phone calls. A report notes fake “@state.gov” addresses add credibility. As a result, victims disclose info easily.
Impact on Users
Victims face credential theft and malware infections. Attackers pose as support staff during calls. Moreover, banking trojans gain persistent access. This exposes users to financial and data risks.
Broader Phishing Trends
Similar attacks exploit Microsoft 365 Direct Send. They spoof internal emails to bypass scrutiny. For example, Luna Moth targets networks with IT ruses. As a result, phishing evolves with new vectors.
Challenges for Detection
The PDFs hide malicious intent in annotations. VoIP numbers mask attacker locations. Additionally, AI misleads users to fake sites. This complicates efforts to spot and block scams.
Future Cyber Risks
Threat actors poison AI with fake GitHub APIs. They manipulate search results via Hacklink. For instance, fake tutorials promote malicious code. Therefore, online deception grows more sophisticated.
Preventing Hacker PDF Attacks
To stop these attacks, avoid clicking PDF links or QR codes. For example, verify sender emails before calling. Use antivirus software and enable email filters. Additionally, educate staff on phishing signs. These steps help protect against brand impersonation.
