Security experts are warning of newly discovered information-stealing malware designed to render the victim’s machine useless by destroying its master boot record if it believes it’s being analyzed by security tools.

Rombertik is a complex piece of malware designed to steal information from a user’s browser in a similar way to banking trojan Dyre, according to Cisco. It typically propagates via spam and phishing emails, using social engineering to trick the user into opening a malicious attachment.

However, it features “several layers of obfuscation along with anti-analysis functionality” designed to foil security researchers, the vendor said in a blog post.

The first is to include a large volume of “garbage code” – 97% in fact – designed to make the packed file appear legitimate and “overwhelm analysts by making it impossible to look at every function.”

It also tries to evade sandboxing – attempting to delay execution by writing a byte of random data to memory 960 million times.
