Malicious3 computer code is making the spook's job easier than ever
IT IS 30 years since William Gibson, an American-Canadian author, wrote “Neuromancer”, in which he coined the term “cyberspace” and imagined a future of hackers4 for hire and giant corporations raiding each other's computer systems in search of secrets. He was right about the direction of travel, but wrong about some of the details. For it is governments, not corporations or anti-social teenagers, who have become the world's best hackers.
The latest example came on November 23rd, when Symantec, an American antivirus firm, announced the discovery of a piece of software called Regin, which it had found lurking5 on computers in Russia, Saudi Arabia and several other countries, sniffing6 for secrets. Its sophistication and stealth led Symantec to conclude that it must have been written by a nation-state.
Regin (the arbitrarily chosen name comes from a text string found in the bug's innards) is only the latest in a long line of government-sponsored malware (see table). The most famous is Stuxnet, discovered in 2010, which was designed, almost certainly by America and Israel, to hijack7 industrial-control systems. It was deployed8 against Iran's nuclear programme, and destroyed centrifuges that were being used to enrich uranium. Unlike the vast surveillance dragnets revealed by Edward Snowden, a former American contractor9 who leaked thousands of secret documents in 2013, these computerised bugs10 are tailored and aimed at defined targets.
The sort of direct sabotage11 carried out by Stuxnet is unusual. Most government malware (or at least, most that security researchers know about) seems to be for information-gathering. In 2006, for instance, it emerged that someone had hacked electronic equipment belonging to Vodafone's Greek subsidiary and listened to the mobile-phone conversations of the Greek cabinet. But such attacks can still do damage: Regin's most common targets were individuals and small businesses, but telecoms firms, energy companies and airlines were affected12, too.
Working out who has created a piece of malware is not easy. Computer code has no nationality. Programmers sometimes leave hints, or use suggestive phrases, but these are not proof. The targets can provide clues, as can comparisons with known malware. DarkHotel, which targets corporate13 executives and other bigwigs by hijacking14 hotel Wi-Fi systems and which was discovered only weeks before Regin, has been tentatively pinned on South Korea. Korean characters, and a reference to a known South Korean coder, were found in its code. The targets included people from Taiwan, Japan, China—and a few from America, South Korea's most important ally.
There are similar clues in Regin. Symantec says Regin's most frequent targets were computers in Russia, which accounted for 28% of the total, and Saudi Arabia, which made up 24%. But the full list includes countries as diverse as Afghanistan, Ireland and Mexico. One of Regin's modules15 is called “LEGSPIN”, a cricketing term. And experts say that it seems very similar to malware used in an attack on Belgacom, a Belgian telecoms firm, in which the British are the chief suspects. (Government Communications Headquarters, Britain's electronic-spying agency, refused to comment.) But such clues may be designed to mislead: when the Russians began their computerised espionage, they would often try to make it seem as if the software was Chinese. “They hid behind China's notoriety,” says Mikko Hypponen of F-Secure, a Finnish computer-security firm.
Such deniability is one attraction of computerised espionage. Another is that modern software is so complex that it is riddled16 with security holes, most of which can be exploited from a safe distance. Once one is found, data can easily and cheaply be smuggled17 out and sent round the world.
This means that the big powers are not the only cyber-spies. The cutting-edge stuff is done by America, China and Russia, says Mr Hypponen, but F-secure thinks Pakistan, North Korea and some African countries are doing it, too. The low cost means that governments and firms can expect to suffer from more and more of it. Some are already taking drastic measures: Russia has ordered 20 typewriters, reportedly because of the vulnerability of computers. To paraphrase18 Mr Gibson: it seems that the future is already here, and it is becoming ever more evenly distributed.
