►Software giant Microsoft’s Greece headquarters was firebombed [1] early Wednesday morning by three men who drove a van into the front of the building, then poured gasoline in the building. "While a motive was not clear, small armed anarchist or domestic terrorist groups have set off attacks in Greece for decades. They usually target official buildings, banks or symbols of state power with small bombs or incendiary devices and rarely cause injuries,” the Associated Press reports. The men held the building's security guards at gunpoint before backing the van through the front door. Other than the guards, no staff were in the building.

Anthrax, monkeypox, dangerous strains of influenza and the SARS virus are examples,” USA Today reports. Bioterror agents were never at risk of falling into the wrong hands, a CDC spokesman said.

The site was configured in a way to allow the investigators to monitor and record all activities on the site, as well as the IP addresses of the people who came to the site to sell, share, or buy stolen data. Access to the site was restricted to registered users, who had to provide a valid email address,” PCMag.com reports.
