Twitter has acquired anti-malware startup Dasient. Financial terms of the deal, announced Monday, were undisclosed.

Twitter chirps about acquisiton

Dasient launched a web-based anti-malware platform in 2009, following up with technology designed to restrict the spread of malicious ads a year later. In joining Twitter, Dasient said it plans to wind down its existing businesses in order to concentrate its resources on making Twitter more secure.

Twitter bought Whisper Systems, employer of noted security researcher Moxie Marlinspike, to boost its efforts in encryption last November, so the Dasient deal is not the first time the micro-blogging biz has brought in third-party security expertise. ®
