David Corn reports in Mother Jones that Russian hackers broke into the Trump cyber network.
Four years ago, the Trump Organization experienced a major cyber breach that could have allowed the perpetrator (or perpetrators) to mount malware attacks from the company’s web domains and may have enabled the intruders to gain access to the company’s computer network. Up until this week, this penetration had gone undetected by President Donald Trump’s company, according to several internet security researchers.
In 2013, a hacker (or hackers) apparently obtained access to the Trump Organization’s domain registration account and created at least 250 website subdomains that cybersecurity experts refer to as “shadow” subdomains. Each one of these shadow Trump subdomains pointed to a Russian IP address, meaning that they were hosted at these Russian addresses. (Every website domain is associated with one or more IP addresses. These addresses allow the internet to find the server that hosts the website. Authentic Trump Organization domains point to IP addresses that are hosted in the United States or countries where the company operates.) The creation of these shadow subdomains within the Trump Organization network was visible in the publicly available records of the company’s domains.
There’s much more in the article itself, but the first thing that occurs to me is blackmail.
