Google has two times more malware than Bing, Yahoo! and Twitter combined
Posted on 29 July 2010.
Barracuda released its Barracuda Labs 2010 Midyear Security Report, revealing data from two key areas: search engine malware and Twitter use and crime rate.


Searching for malware

Barracuda Labs conducted a study across Bing, Google, Twitter and Yahoo!, over a roughly two-month period. The analysis reviews more than 25,000 trending topics and nearly 5.5 million search results. The purpose of the study was to analyze trending topics on popular search engines to understand the scope of the problem and to identify the types of topics used by malware distributors.

Key highlights from the search engine study include:
  • Overall, Google takes the crown for malware distribution Ė turning up more than twice the amount of malware as Bing, Twitter and Yahoo! combined when searches on popular trending topics were performed. Google presents at 69 percent; Yahoo! at 18 percent; Bing at 12 percent; and Twitter at one percent.
  • The average amount of time for a trending topic to appear on one of the major search engines after appearing on Twitter varies tremendously: 1.2 days for Google, 4.3 days for Bing, and 4.8 days for Yahoo!
  • Over half of the malware found was between the hours of 4:00 a.m. and 10:00 a.m. GMT.
  • The top 10 terms used by malware distributors include the name of a NFL player, three actresses, a Playboy Playmate and a college student who faked his way into Harvard.
The dark side of Twitter

Barracuda Labs analyzed more than 25 million Twitter accounts, both legitimate and malicious. The purpose of this part of the study was to measure and analyze account behavior on Twitter in order to model normal user behavior and identify features that are strong indicators of illegitimate account use. The study reviews several key areas including True Twitter Users, Twitter Crime Rate, and Tweet Number.

Key highlights from the Twitter research include:
  • In general, activity is increasing on Twitter: more users are coming online; True Twitter Users are tweeting more often, and even casual users are becoming more active. As users become more active, the malicious activity also increases.
  • Only 28.87 percent of Twitter users are actual True Twitter Users.
  • Half of Twitter users tweet less than once a day, yet one in 10 users tweet five or more times a day and 30 percent of Twitter accounts have never tweeted.
  • One in every eight Twitter users has at least 10 times more followers than they are following.
  • Only one in 10 users is following more than 100 users, and almost half are following less than five.
  • The Twitter Crime Rate for the first half of 2010 was 1.67 percent.
