PDFs are mostly used in cyberers and already refer to 22% harmful attachments in email – the Internet
The use of pdf files as a “weapon” of cyberatac is growingCzech Point warns researchers. According to the advanced data of experts, PDF files represent 22% of all harmful attachments already promoted by email.
The situation becomes more complicated when the situation comes More than 87% of companies use PDF as standard business communication formatMore than 400 billion files were opened last year and 16 billion documents were revised at Adobe Acrobat.
Cyber Security Company develops it Cybercrimals resort to advanced methods to overcome the identification systems of security solutions, making these attacks very difficult to identify and reduce. Researchers have recognized multiple harmful campaigns that are not detected by traditional security solutions without any recognition recorded in Viristol last year.

But why are the pdf files attractive to cybercrimans? Although it is easy to use, experts explain that it is a kind of complex file for automated systems. The combination of simplicity and complexity of security systems makes them very attractive to those who attack them.
Checkpoint software emphasizes that in recent years harmful PDFs have become more sophisticated. In the past, Cyber Crimeans explored the vulnerability of pdf readers. But now, this approach has become less effective for large -scale attacks with very up -to -date readers, especially those who open the files.
Instead of exploring security failures, the attackers are now betting on social engineering strategies. One of the most common methods is link -based campaigns. In these cases, PDF has link to a fishing site or releases harmful files.
In addition, the link is often with an image or text to persuade customers to click. Images in question often mimic known brands such as Amazon, Document or Acrobat Reader. In these cases, the attackers control all aspects, including the link, text and image, it is easy to quickly change any part, making it more difficult to identify campaigns.
In order to avoid recognition, cybercrimans constantly receive their strategies. URLs are often strategies through the final destination, QR codes or telephone calls to “hide” telephone calls. Aviation for static analysis, as well as the use of methods such as disruption, filters and complex structures to hide machine learning systems and harmful intentions used in safety tools.
To be safe from attacks with pdf files, experts recommend this Always check the sender of messages and email you receive.
