Increased viruses activity at the end of the financial year.
Its true that we all have a tax headache but virus producers often make it more difficult at this time. The virus creators know that they can completely destroy the sanity of small business operators at this time of the year. Especially, the ones that have not backed there tax and financial data for a long time.
Anti virus manufacturers have raised their Threatcon Levels to 2 (Yellow) medium warning people that there is an elevated level of virus activities around. ThreatCon Level 2 applies when knowledge or the expectation of attack activity is present, without specific events occurring or when malicious code reaches a moderate risk rating. Under this condition, a careful examination of vulnerable and exposed systems is appropriate, security applications should be updated with new signatures and/or rules as soon as they become available and careful monitoring of logs is recommended. Changes to the security infrastructure are not required.
Symantec Corperation’s DeepSight Threat Analyst Team is maintaining the ThreatCon at level 2. Attackers have found a vulnerability in Excel that allows them to execute arbitrary code when a maliciously crafted Excel document is opened. Microsoft is aware of this issue and is working on creating a patch. Currently this vulnerability is known to have been used only in a single targeted attack. Administrators are advised to refer to the Unpatched Microsoft Excel Vulnerability Discovered threat alert for details.
