p. 102 Symantec Corporation Internet Security Threat Report 2013 :: Volume 18 MALICIOUS CODE TRENDS Analysis of Malicious Code Activity by Geography, Industry Sector, and Company Size Background Malicious code activity trends can also reveal patterns that may be associated with particular geographical locations, or hotspots. This may be a consequence of social and political changes in the region, such as increased broadband penetration and increased competition in the marketplace that can drive down prices, increasing adoption rates. Of course, there may also be other factors at work, based on the local economic conditions that may present different risk factors. Similarly, the industry sector may also have an influence on an organization’s risk factor, where certain industries may be exposed to different levels of threat, by the nature of their business. Moreover, the size of an organization can also play a part in determining their exposure to risk. Small to medium-sized businesses (SMBs) may find themselves the target of a malicious attack by virtue of the relationships they have with other organizations; for example, a company may be subjected to an attack because they are a supplier to a larger organization and attackers may seek to take advantage of this relationship Data in forming the social engineering behind subsequent attacks to the main target, using the SMB as a springboard for these later attacks. SMBs are perceived to be a softer target because they are less likely to have the same levels of in-depth defenses as a larger organization, which is more likely to have greater budgetary expenditure applied to their security countermeasures.
