SolarMarker Malware: A New Threat via PDFs
The hackers behind SolarMarker malware PDFs have begun using an innovative and unexpected method of distributing their poisoned code. However, their strategy involves publishing PDF documents filled with SEO (Search Engine Optimization) keywords to boost the visibility of malicious websites that pose as Google Drive repositories but are, in fact, malware hubs.
How the SolarMarker Malware PDF Scam Works
A potential victim may receive an email containing a PDF that promises information on attractive insurance rates or credit card deals. For example, clicking on the links in the PDF redirects the victim to a site designed to resemble Google Drive. Once there, users are instructed to download a file from the drive. Unfortunately, clicking on this file delivers the malware to their system.
The Role of SEO in Spreading SolarMarker Malware PDFs
SEO is a legitimate marketing tactic used by businesses to increase site traffic. However, in this case, hackers have co-opted the method for malicious purposes. Moreover, this approach has proven highly effective, allowing SolarMarker malware PDFs to reach more victims. Therefore, understanding this methodology is essential for businesses and individuals to stay protected.
What Does SolarMarker Malware Do?
SolarMarker is a backdoor malware designed to steal login credentials and other data from web browsers. While the malware itself is not directly destructive, it enables hackers to:
- Introduce more damaging malware.
- Steal a victim’s identity.
- Access sensitive accounts using stolen credentials.
In addition, the stolen data can be sold on the dark web or used to launch further attacks on the victim or their organization.
Who Is Being Targeted?
Crowdstrike, the first company to sound the alarm, discovered the unusual marketing campaign for SolarMarker. At the moment, researchers noted that the malware’s creators are focusing their efforts on North America. However, this does not mean that users in other regions are safe from potential exposure.
Why This Attack Is Unique
PDFs have long been a common method for delivering malicious payloads. However, the methodology employed by SolarMarker malware PDFs is both unusual and noteworthy. The combination of SEO manipulation and convincing phishing techniques makes this attack especially dangerous. As a result, it has become one of the most effective malware distribution methods seen recently.

- Avoid clicking on links in suspicious PDF documents.
