Regionalized malware rising

Cybercriminals are increasingly crafting attacks in multiple languages and are exploiting popular local applications to maximize their profits, according to a new McAfee report released today.

McAfee Avert Labs examined global malware trends in its third Sage report, titled “One Internet, Many Worlds.” The report is based on data compiled by McAfee’s international security experts and examines the globalization of threats and the unique threats in different countries and regions. In the report the following trends and conclusions and detailed:

  • Sophisticated malware authors have increased country-, language-, company-, and software-specific attacks.
  • Cyberattackers are increasingly attuned to cultural differences and tailor social engineering attacks accordingly.
  • Cybercrime rings recruit malware writers in countries with high unemployment and high levels of education such as Russia and China.
  • Cybercriminals take advantage of countries where law enforcement is lax.
  • Around the world, malware authors are exploiting the viral nature of Web 2.0 and peer-to-peer networks.
  • More exploits than ever before are targeted at locally popular software and applications.

Geographical trends

The United States: the great malware melting pot

Once the launching pad of all malware, today malware in the US includes elements of malicious software seen around the world. Attackers use increasingly clever social engineering skills to trick victims and are looking to exploit the viral nature of Web 2.0. Although the United States has cybercrime laws in place, the lack of international cybercrime laws and the differences in extradition treaties make it difficult for enforcement agents to prosecute criminals across borders.

Europe: malware learns the language

With 23 languages in the European Union alone, language barriers used to be a hurdle for miscreants. Consumers in non-English speaking countries often simply deleted English-language spam and phishing e-mail. Today malware authors adapt the language to the Internet domain site where the scam message is being sent, and malicious Web sites serve up malware in a language determined by the country the target is located in. Cultural events such as the FIFA soccer World Cup in the summer of 2006 prompted email scams and phishing sites luring in soccer lovers. With the increased sophistication of malware, computer users in the EU are under attack.

China: virtual entertainment

With more than 137 million computer users — a quarter of whom play online games — malware authors are cashing in on virtual goods, currency, and online games. A majority of the malware found in China is password-stealing Trojans — designed to steal users’ identities in online games and their credentials for virtual currency accounts. China has also become a breeding ground for malware writers, as a large number of skilled coders do not have legitimate work. The conditions have driven these hackers to cybercrime in search of money.

Japan: losing to Winny – malware spreads from peer to peer

Winny, a popular peer-to-peer application in Japan, is prone to malware infestations that can cause serious data leaks. When deployed in the corporate setting, malware on Winny can expose data, steal passwords, and delete files. Unlike in most countries, malware authors in Japan are not motivated by money — instead authors seek to expose or delete sensitive data on machines. Another common target in Japan is Ichitaro, a popular word processor. There have been several attacks against Ichitaro users that exploited unpatched security vulnerabilities to install spyware on the target machines.

Russia: economics, not mafia, fuel malware

The technical skills of Russians in a stumbling economy make for an active market of hackers. Some of the most notorious attack toolkits are produced in Russia and sold in underground markets. These gray-market malware tools, combined with lack of legislation against cybercrime, lead experts to believe that the Russian mafia will soon — if they haven’t already — latch onto computer crime. Although the Russian economic situation, like that of China’s, has driven many hackers to a life of cybercrime, Avert Labs predicts that with a strengthening economy and stronger law enforcement, Russian-made malware will gradually decrease.

Brazil: bilking the bank

Miscreants have made an international showcase out of Brazil when it comes to bilking online bank accounts. With a majority of Brazilians banking online, cybercrooks use sophisticated social engineering scams to trick Brazilians into giving up personal information. In 2005 alone, the Brazilian Banks Association estimated losses at R$300 million (about $165 million USD) due to virtual fraud. Malware creators rapidly adapt password-stealing Trojans to the changes banks make to their Web sites.
