The bad actors kick off the initial access attempt via a PDF document named 'Remittance Invoice' that is attached to an email, according to HP. The campaign HP began tracking earlier this year aims to trick marks into running the information-stealing Snake Keylogger on their PCs, and relies on multiple techniques for evading detection, including embedding malicious files, loading remote-hosted exploits, and shellcode encryption, HP's SchlГ¤pfer wrote. Enterprises also can use tools like DMARC for email authentication, he said. PDFs can also include clickable links and JavaScript, which can be exploited for malicious purposes.'ДЄs with any phishing attempt, the cybercrook's goal is to trick users into opening malicious documents, accepting macros in embedded files, or doing something else that will lead to malware infection, which means it's important for organizations to ensure their employees are trained to not open documents from unknown or untrusted sources. 'They can interact with remote sites, launch local programs and contain embedded files. 'PDF files have capabilities similar to those of a web page,' Righi said.

PDFs are a threat that enterprises need to understand, Ivan Righi, senior threat intelligence analyst at Digital Shadows, told The Register. They noted that in 2018, there were at least 47,000 attacks involving PDF files and that the number rose to 173,000 in the first quarter of 2019. Unfortunately, the trust that users have in PDFs as a 'safe' document is false.' After all, that's why you issue an invoice as a PDF file and not a Word document.

PDF is a document type that people trust. In a 2019 report, researchers at cybersecurity firm TitanHQ found that to be effective, phishing campaigns need to create a sense of urgency or surprise as well as a sense of trust. While they may not be used at the same rate as Office files, cybercriminals have seen advantages in using PDFs for fraud and malware campaigns. 'The reasons are clear: users are familiar with these file types, the applications used to open them are ubiquitous, and they are suited to social engineering lures,' Patrick SchlГ¤pfer, malware analyst at HP, explained in a write-up, adding that in this latest campaign, 'the malware arrived in a PDF document вЂ“ a format attackers less commonly use to infect PCs.' About 45 percent of malware stopped by HP's threat intelligence team in the first quarter of the year leveraged Office formats.

For a decade, miscreants have preferred Office file formats, such as Word and Excel, to deliver malicious code rather than PDFs, as users are more used to getting and opening.

HP's cybersecurity folks have uncovered an email campaign that ticks all the boxes: messages with a PDF attached that embeds a Word document that upon opening infects the victim's Windows PC with malware by exploiting a four-year-old code-execution vulnerability in Microsoft Office.Д«ooby-trapping a PDF with a malicious Word document goes against the norm of the past 10 years, according to the HP Wolf Security researchers.
