The vulnerability can be exploited in two ways: on a Web site that allows users to enter names or other details that are part of the PDF file generation process, such as when adding names or other details to an invoice, and second, on a Web site that contains cross-site scripting (XSS) vulnerabilities, an attacker can plant malicious code in HTML source code that will be provided to the TCPDF library and converted to PDF files. The trick is to provide the TCPDF library with misformated data, modify the data in this way, force the TCPDF library to call the PHP server's "phar://" stream wrapper, and then abuse the PHP anti-serialization process to run code on the underlying server. Attack routines are complex and require advanced PHP coding knowledge to exploit, and desercation vulnerabilities are difficult to detect and affect Ruby, Java, and .NET in addition to PHP.

Users can use two-factor authentication for Electrum wallets. This also adds extra security to the wallet.

Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
