Symantec Hosted Services' Top 5 Security Threats
The top five security threats you need to be on the lookout for.
According to the 3rd Quarter Threat Report from Cisco, enterprise users experienced an average of 133 Web malware encounters per month, peaking at over 140 during the month of August. Most of the encounters are happening through search engine traffic and services, with the majority, not surprisingly, coming via Google-seeing that nearly three-quarters of all searches happen on Google.
Another finding in the report was the favorite target of malware attacks through spam came through LinkedIn spoofed mail, making up nearly 32 percent of all spam sent. To refresh your memory, the LinkedIn spoof claimed to remind users of a forgotten contact invite, but instead led to a link infected with the Zeus Trojan.
I found the report interesting. It showed that areas that have been of concern over the past year, like exploits that target Adobe products, are decreasing. Personally, I'll be watching to see what happens with the Stuxnet botnet. Right now, this dangerous piece of malware, which is being called a "game changer" in national cybersecurity, ranked as the 5th most frequently encountered event for Cisco's Remote Operations Service, making up just 5 percent of the events handled. An article in PC World stated:
Stuxnet, likely developed by a well-financed team, modifies files of the software running industrial control systems and can also steal the data contained there without the owner knowing it.
The major concern of the malware is its threat on our utilities infrastructure. Right now, the U.S. is not in Cisco's list of top 5 countries impacted by Stuxnet. I hope that remains to be the case come the end of the 4th quarter.
