Symantec MessageLabs Intelligence October 2010 Report – Targeted Email Attacks On The Rise

imageEven in a world where Internet threats present an ever evolving and increasingly sophisticated danger to businesses, targeted email attacks are the most potent of all – potentially dealing  devastating short and long-term damage to the victims.

Counter to intuitive thinking, a high degree of sophistication gives these low volume, highly personalized emails an edge, and a higher probability of success than mass email blasts.

The goal of targeted attacks is simple – an attempt to gain access to specific sensitive data, intellectual property or confidential internal systems, by targeting specific individuals and companies.

According to Symantec Hosted Services, targeted attacks on the retail sector took a big jump in October, with 25 percent of all targeted attacks directed at this economic sector.

When you consider that in the previous 2 years, less than half of one percent of targeted email attacks were directed at the retail sector – versus the 25% discovered by Symantec Hosted Services in October, it’s evident cyber crooks have a razor sharp focus on the retail sector.

The spam landscape changes constantly, and while your industry sector may not be in the crosshairs currently, given that 200 and 300 organizations are targeted each month with the industry sector varying, it may be only a matter of time.

Knowledge is power, and as computer users we need as much power as we can get in order to stay safe on the Internet, so I encourage you to read the highlights of MessageLabs Intelligence October report, just released today. The full report is available here.

Selected report highlights:

Spam: In October 2010, the global ratio of spam in email traffic from new and previously unknown bad sources was 87.5 percent (1 in 1.4 emails), a decrease of 4.2 percentage points since September.

Viruses: The global ratio of email-borne viruses in email traffic from new and previously unknown bad sources was one in 221.9 emails (0.45 percent) in October, an decrease of .01 percentage points since September. In October, 23.1 percent of email-borne malware contained links to malicious websites, an increase of 15.5 percentage points since September.

Endpoint Threats: Threats against endpoint devices such as laptops, PCs and servers may penetrate an organization in a number of ways, including drive-by attacks from compromised websites, Trojan horses and worms that spread by copying themselves to removable drives. Analysis of the most frequently blocked malware for the last month revealed that the Sality.AE virus was the most prevalent. Sality.AE spreads by infecting executable files and attempts to download potentially malicious files from the Internet.

Phishing: In October, phishing activity was 1 in 488.0 emails (0.20 percent), a decrease of 0.06 percentage points since September.

Web security: Analysis of web security activity shows that 51.3 percent of malicious domains blocked were new in October, an increase of 17.7 percentage points since September. Additionally, 24.7 percent of all web-based malware blocked was new in October, an increase of 2.9 percentage points since last month. MessageLabs Intelligence also identified an average of 2,280 new websites per day harboring malware and other potentially unwanted programs such as spyware and adware, a decrease of 23.9 percent since September.
