News of the latest advanced malicious software threat called Regin comes with a silver lining. The good news is most people in the English-speaking world won't have to worry about it.
The bad news? Everyone else does.
Pronounced "region," the malware is a cyber-espionage tool built to steal the secrets of many foreign governments and businesses, said a report published Sunday by security specialist Symantec. Regin avoids detection with a specialized design as it ferrets out critical information. It's been used since 2008 to infiltrate email databases, monitor network traffic, steal passwords, snag screenshots and record mouse clicks.
Regin could represent a new, more advanced wave, something Symantec called "groundbreaking" and "almost peerless" in its report. Why is it so special? Who it targets, and who it doesn't.
While many of the documents leaked by National Security Agency contractor Edward Snowden last year point to espionage committed against the closest of US allies, Regin appears to have spared five English-speaking countries: The US, the United Kingdom, Australia, New Zealand and Canada. Among the countries where researchers detected infections were Germany, Russia, Saudi Arabia, Syria, Brazil, Belgium, Mexico, and India, but also Ireland -- part of the UK.
Systems Affected: Microsoft Windows NT, 2000, XP, Vista, and 7
On November 24, 2014, Symantec released a report on Regin, a sophisticated backdoor Trojan used to conduct intelligence-gathering campaigns. At this time, the Regin campaign has not been identified targeting any organizations within the United States. Description Regin is a multi-staged, modular threat—meaning it has a number of components, each dependent on others to perform an attack. Each of the five stages is hidden and encrypted, with the exception of the first stage. The modular design poses difficulties to analysis, as all components must be available in order to fully understand the Trojan. Impact Regin is a remote access Trojan (RAT), able to take control of input devices, capture credentials, monitor network traffic, and gather information on processes and memory utilization. The complex design provides flexibility to actors, as they can load custom features tailored to individual targets.
Solution: Users and administrators are recommended to take the following preventive measures to protect their computer networks:
Use and maintain anti-virus software – Anti-virus software recognizes and protects your computer against most known viruses. It is important to keep your anti-virus software up-to-date (see Understanding Anti-Virus Software for more information). [2 (link is external)]
Keep your operating system and application software up-to-date – Install software patches so that attackers can't take advantage of known problems or vulnerabilities. Many operating systems offer automatic updates. If this option is available, you should enable it (see Understanding Patches for more information).
The following is a list of the Indicators of Compromise (IOCs) that can be added to network security solutions to determine whether they are present on a network.

As you can see in the article, even knowing the hashes is kind of a moot point since most of the files don't even show up in a standard filesystem.
