Malware targeting ex-Soviet states has Russian hallmarks

A malicious software that has infiltrated the computer systems of dozens of embassies belonging to former Eastern Bloc nations “has all the hallmarks of a nation-state” cyberespionage operation, according to researchers. Security firm Symantec said last week that the malware appears to be specifically targeting embassies of former communist nations located in China, Jordan, as well as in locations across Western Europe. In a report published on its website, Symantec said “only a nation state” was likely to have the funds and technical resources to create a malware of such complexity. Additionally, the malware seems to be designed “to go after explicit government networks that are not easy to find”, according to Symantec senior security researcher Vikram Thakur. The infiltration appears to occur in two stages. In the first stage, a computer is infected with a reconnaissance program, known as Wipbot. The initial infection usually occurs through a directed phishing attack or via a compromised website. The Wipbot then conducts an initial exploration of the infected system, collecting vital information about its identity, structure and contents. It then proceeds to compromise it only if it matches a specific Internet address that it is looking for. If a match is confirmed, the Wipbot then invites a second program into the compromised system, whose task is to expropriate data and exfiltrate it in batches that are camouflaged as Internet browser requests. Symantec researchers say that the technical similarities between the two programs are sufficient to justify the view that they were designed and developed by programmers working for the same government agency. Thakur said the structure of the malware is particularly creative; it uses Wipbot as an initial reconnaissance tool before delivering the exfiltration program if it judges that the compromised system is of high enough interest. The Symantec report adds that the malware in question is part of a four-year-long series of cyberespionage attacks that have systematically targeted government facilities belonging to former Communist Bloc states. In May of 2012, a similar malware was found to have infiltrated over 60 different computer systems belonging to a former Soviet Republic, including the office of the Prime Minister. A closely linked attack targeted another former communist state’s embassy in Paris, France, as well as its foreign and internal affairs ministries. The Symantec research points out that many of the malicious program’s core components were compiled in the UTC+4 time zone, which includes Russian cities such as Moscow and St. Petersburg.
