Back in November 1988, Robert Tappan Morris, son of the famous cryptographer Robert Morris Sr., was a 20-something graduate student at Cornell who wanted to know how big the internet was — that is, how many devices were connected to it. So he wrote a program that would travel from computer to computer and ask each machine to send a signal back to a control server, which would keep count.

Unpacking the Morris Worm

Worms and viruses are similar but different in one key way: A virus needs an external command, from a user or a hacker, to run its program. A worm, by contrast, hits the ground running all on its own. For example, even if you never open your email program, a worm that gets onto your computer might email a copy of itself to everyone in your address book.

In an era when few people were concerned about malicious software and nobody had protective software installed, the Morris worm spread quickly. It took 72 hours for researchers at Purdue and Berkeley to halt the worm. In that time, it infected tens of thousands of systems — about 10 percent of the computers then on the internet. Cleaning up the infection cost hundreds or thousands of dollars for each affected machine.

In the clamor of media attention about this first event of its kind, confusion was rampant. Some reporters even asked whether people could catch the computer infection. Sadly, many journalists as a whole haven’t gotten much more knowledgeable on the topic in the intervening decades.

Rising Threats

The internet remains subject to much more frequent — and more crippling — DDoS attacks. With more than 20 billion devices of all types, from refrigerators and cars to fitness trackers, connected to the internet, and millions more being connected weekly, the number of security flaws and vulnerabilities is exploding.

In October 2016, a DDoS attack using thousands of hijacked webcams — often used for security or baby monitors — shut down access to a number of important internet services along the eastern US seaboard. That event was the culmination of a series of increasingly damaging attacks using a botnet, or a network of compromised devices, which was controlled by software called Mirai. Today’s internet is much larger, but not much more secure, than the internet of 1988.

Some things have actually gotten worse. Figuring out who is behind particular attacks is not as easy as waiting for that person to get worried and send out apology notes and warnings, as Morris did in 1988. In some cases — the ones big enough to merit full investigations — it’s possible to identify the culprits. A trio of college students was ultimately found to have created Mirai to gain advantages when playing the Minecraft computer game.

Fighting DDoS Attacks

But technological tools are not enough, and neither are laws and regulations about online activity — including the law under which Morris was charged. The dozens of state and federal cybercrime statutes on the books have not yet seemed to reduce the overall number or severity of attacks, in part because of the global nature of the problem.

More organizations are also taking preventative action, adopting best practices in cybersecurity as they build their systems, rather than waiting for a problem to happen and trying to clean up afterward. If more organizations considered cybersecurity as an important element of corporate social responsibility, they — and their staff, customers, and business partners — would be safer.

In 3001: The Final Odyssey, science fiction author Arthur C. Clarke envisioned a future where humanity sealed the worst of its weapons in a vault on the moon — which included room for the most malignant computer viruses ever created. Before the next iteration of the Morris worm or Mirai does untold damage to the modern information society, it is up to everyone — governments, companies, and individuals alike — to set up rules and programs that support widespread cybersecurity, without waiting another 30 years. source
