New FormBook Droppers Point to Future Threat

New FormBook Droppers Point to Future Threat (Malware and Vulnerabilities)

Never-before-seen dropper found in FormBook samples that has increased persistence and obfuscation capabilities. Researchers are warning that a future data-theft attack may be brewing after discovering a new sample of the FormBook malware, with a never-before-seen dropper — i.e. a malicious file that is used in the initial infection stage and installs malware on the system. Just recently,  researchers discovered the malware harboring the new dropper, that they said has capabilities to better achieve persistence on systems and obfuscation to avoid detection, according to Wednesday Cyberbit research exclusively shared with Threatpost. However, unlike in other samples, the new dropper doesn’t merely unpack the malware, but instead installs a file that creates two post-infection processes.
