How does 'pdf-to-office' malware operate?
According to report Presented by ReversingLabs, the attack begins when users download the npm package “pdf-to-office,” which presents itself as a tool for converting PDF files to Office formats.
However, instead of performing the promised function, The package contains malicious code that looks for local installations of specific cryptocurrency wallets, including Atomic Wallet and Exodus. Once detected, the malware proceeds to modify key files within these applications.
The modification consists of replace legitimate JavaScript files within the “resources/app.asar” file with nearly identical trojanized versions. The critical difference is that these altered versions They replace the user's intended recipient address with a wallet address controlled by the attackers.. In this way, when the user makes a transaction, the funds are inadvertently sent to the attacker's wallet instead of to the legitimate recipient. This process is done silently and without alerting the user, making the attack difficult to detect.
ReversingLabs has noted that this campaign is an example of a growing trend in which attackers distribute packages designed to patch local installations of trusted software with malware. Thus, rather than directly compromising open source libraries, which are often reviewed by the community, attackers focus on modifying individual installations, allowing them to bypass traditional software supply chain defenses.
The attackers' tactics: stealth and persistence
One of the most worrying features of this attack is its stealth. The malware installs and modifies cryptocurrency wallets. without showing obvious signs of malicious activity. Trojanized files are almost identical to the originals, making them difficult to detect using visual inspection or conventional security tools.

According to the cybersecurity firm, after the original "pdf-to-office" package was removed from npm, a republished version with the same name and version briefly reappeared, indicating that the attackers are determined to continue their malicious campaign. This persistence underscores the need for continued vigilance and proactive security measures.
Another tactic used by attackers is obfuscation of malicious codeThe report notes that the code within the "pdf-to-office" package is obfuscated to make it difficult to analyze and understand. This allows attackers to hide the malware's true functionality and evade detection by security analysts.
