One in 200 Google Search Suggestions “Malicious”
According to a recent study by US university researchers, one of every 200 Google search autocomplete suggestions are used to drive traffic to malicious sites and content such as malware.
The researchers said that they were able to identify several companies that offer blackhat search engine optimization (BHSEO) techniques are used to manipulate autocomplete search queries for around $1 to $20 per day.
The study showed that mainstream search engines such as Google, Yahoo, and Bing had 383K manipulated suggestions (across 257K triggers), particularly Google that had at least 0.48% of its results ‘polluted’. The researchers also warned that the technique may grow in popularity on mobile devices where users typically do not type out the whole query.
