But they have found evidence to back claims that the attacks that downed Twitter and affected Facebook, YouTube and Live Journal were aimed at a pro-Georgian activist.
ITN report on Twitter attacks last week:
Twitter co-founder Biz Stone said in a blog post on Friday that the "ongoing, massively coordinated attacks on Twitter" appeared to have been "geopolitical" in motivation.
But Twitter did not feel it was appropriate to "engage in speculative discussion about these motivations", he wrote.
Security firm McAfee has identified six separate DDoS attacks on accounts with these services registered to a user known as "Cyxymu" who is linked to anti-Russian protests.
Cyxymu's Gmail account was also targeted by a simultaneous spam e-mail campaign.
According to McAfee, the attacks were carried out by a botnet made up of hijacked computers in Brazil, Turkey and India.
Twitter claims no data or personal information of any kind has been compromised in the DDoS attack. The company has committed to improving system responses to assaults to ensure they do not interfere with the microblogging service.
