Many Twitter users were confused and alarmed this morning by an email from the service saying that their accounts had been “compromised” and forcing them to change their passwords. Read more

no to spamAt first this looks so promising. Volumes of spam are down nearly 70 per cent from last year according to a report from Symantec, the IT security company. In June, there were 39.2bn unsolicited, “spam” messages in circulation each day, compared with 121.5bn a day in June 2010. This echoes findings earlier this month from rival McAfee, which suggested spam levels had halved in the last year.

But sadly, this doesn’t mean we are winning the war on cybercriminals and botnets. Rather, it is a reflection on how use of the internet is evolving to become more centred around social networking sites and mobile phones. Spam on Twitter and Facebook is becoming a growing problem. Read more

There has been an increasing amount of talk from high places, including the White House, about the urgent need for international  cooperation on cybersecurity. But a proposal to be released tomorrow calling for specific US-China steps shows, more than anything, how far we have to go. Read more

This time last year, Twitter wrote a somewhat smug blog post trumpeting its success in tackling spam. It had reduced the percentage of tweets that were spammy from a peak of almost 11 per cent in summer 2009 to less than 1 per cent in February 2010, it said. Everyone was very pleased.

Google has hit back at growing criticism of the quality of its search results, with a blog post pledging to tackle “content farms” and admitting: “We can and should do better.”

The move has been seen as a threat to Demand Media, one such producer of low-cost articles and videos designed to suck up search traffic, which has just priced its initial public offeringRead more

After taking so much flack for its frequent outages and the regular attacks on its system, it is only fair that Twitter gets to toot its own horn once in a while.

In a bit of very good news for the company, Twitter says it has finally gotten spam on the site under control.

As Twitter was going through its major growth spurt last year, spammers and scammers flocked to the site. From May through October, as much as 9 per cent of all tweets were spam, according to Twitter’s own numbers. Now that number is down to about 1 per cent, said Twitter chief scientist Abdur Chowdhury in a blog post. Read more

“No, Your Social Networking ‘Friend’ Isn’t Really in Trouble Overseas” — That’s the title of a press release put out yesterday by the Federal Bureau of Investigation.

The release was a warning to users of social networking sites, encouraging them to be sceptical of suspicious requests, even if they look like they are coming from friends. In a recent popular scam, fraudsters have been infiltrating accounts, announcing they are in trouble overseas, and asking their friends for money. Read more

How much does spam cost? It’s hard to quantify in terms of bandwidth, time and effort blocking it, and general nuisance. But here’s a figure to mull over: $873m.
