DNS was first conceived in 1983, back when one of the most memorable movie quotes of all time was popularized: “Go ahead, make my day” (Clint Eastwood in “Sudden Impact”). The internet as we know it today did not yet exist; however, ARPANET, its predecessor network, was the exclusive domain of a small group of academics and researchers, so no one gave much thought to security. A lot has changed.

Rich Policy Language DNS

Posted on August 10, 2017 in: Network, Security

Tags: , ,

For many years ISPs in certain parts of the world have been required by their regulators/governments to redirect certain websites that were deemed malicious or suspicious. DNS offered a straightforward way to do this; and Nominum, being a DNS company, developed an early mechanism using a DNS zone file that made it simple for ISPs to comply. The technology was originally named “Malicious Domain Redirection” (MDR), and it basically allowed DNS server operators to perform a single action for a given domain name. Actions could be categorized so that each action or redirection did not have to be repeated.

Petya/NotPetya: Ransomware Attacks in a New Form, but is it Ransomware?

By Yohai Einav, Principal Security Researcher


Posted on July 26, 2017 in: Security

Ransomware has changed a lot since it was introduced back in 1989 by Dr. Joseph Popp, where 20,000 floppy disks were distributed via snail mail. The malware hid files on a victim’s hard drive and encrypted only the file names, rather than the entire files themselves. As one might assume, the entire remediation process was manual, rather than digital. Popp’s program asked victims to print the ransom note and send $189 to a bank in Panama. When he was caught, he was determined unfit to stand trial. All the money he obtained was donated to AIDS research.
