Microsoft revealed this week that it has helped disrupt more than 500 different strains of malware in an attempt to slow the emerging threat of the Nitol botnet. In an operation codenamed b70, Microsoft discovered retailers in China selling computers with counterfeit versions of Windows loaded with malware. Part of an unsecure supply chain, the malware-equipped versions of Windows could have been installed at any part of a process when a computer travels through various companies that transport and resell it.

In a study focusing on the Nitol botnet, Microsoft discovered that 20 percent of the PCs its researchers purchased from an unsecure supply chain in various cities in China were infected with malware. Microsoft Discovers PC Pre-Loaded With Malware [theverge.com]
