Here are eight suggestions.To read this article in full or to leave a comment, please click here

WannaCry attacks are only the beginning

Thousands of organizations from around the world were caught off guard by the WannaCry ransomware attack launched Friday. As this rapidly spreading threat evolves, more cybercriminals are likely to attempt to profit from this and similar vulnerabilities.As a ransomware program, WannaCry itself is not that special or sophisticated. In fact, an earlier version of the program was distributed in March and April and, judging by its implementation, its creators are not very skilled.To read this article in full or to leave a comment, please click here

What to do about WannaCry if you’re infected or if you’re not

Today is likely to be painful for many organizations all over the world that took the weekend off and are returning to the work-week to find hundreds or thousands of computers on their networks encrypted by WannaCry ransomware, which surfaced Friday and has been propagating ever since.Estimates by law enforcement agency Europol estimated yesterday that more than 200,000 computers in 150 countries were infected, but with the worm continuing to spread to vulnerable Windows machines, that number will surely rise.For those whose machines have not been infected, here’s what you need to do right away: Apply the Microsoft patch that will thwart the attack. It’s available here. If you can’t do that because you haven’t tested whether the patch will affect your software build, disable Server Message Block 1 (SMB1) network file sharing. That’s where the flaw is that it attacks. Consider closing firewall port 139, 445 or both because these are the ports SMB uses. Longer term, to guard against similar future attacks you should:To read this article in full or to leave a comment, please click here

IDG Contributor Network: BackupAssist takes a step back in time with a SME backup tool

I live my life in two worlds. The most visible world, at least to this audience, involves spending lots of time in Silicon Valley and the U.S. generally and conversing with the technology illuminati—those who “get” technology, the cloud and what it can offer the world.In my other life, I live in a small (like, tiny) rural village in deepest, darkest New Zealand. I’m surrounded by fine folk, the so-called “salt of the earth” who make a living from the land, sheep, grapes and the rural sector generally. To these folks, technology is simply another tool to add to the arsenal of tools they have at their disposal.+ Also on Network World: Deep dive on AWS vs. Azure vs. Google cloud storage options + For these people, cloud isn’t always an already-adopted opportunity. Rather they use a variety of technology products and services. I have a friend who runs an agricultural service business whose operational software is a DOS-based solution. While this may have friends in the technology world rolling their eyes and shaking their heads, it is the reality of the “real world.” As an aside, I’ve said for the longest time that technology companies Continue reading

It’s Up To Each Of Us: Why I WannaCry For Collaboration

WannaCry, or WannaCrypt, is one of the many names of the piece of ransomware that impacted the Internet last week, and will likely continue to make the rounds this week.

There are a number of takeaways and lessons to learn from the far-reaching attack that we witnessed. Let me tie those to voluntary cooperation and collaboration which together represent the foundation for the Internet’s development. The reason for making this connection is because they provide the way to get the global cyber threat under control. Not just to keep ourselves and our vital systems and services protected, but to reverse the erosion of trust in the Internet.

Worth Reading: Enabling DNSSEC Validation

In July 2010, we saw an important Internet milestone: the Domain Name System (DNS) root zone was signed with DNSSEC, the DNS security extensions. DNS was designed without much thought given to security, but DNSSEC adds much-needed authentication and data integrity features. With DNSSEC, information in the DNS, including the root zone, can be cryptographically signed. DNS clients can validate the resulting signatures to have more trust that the data coming out of DNS is the same as what the owner put in and signed, and that the data hasn’t been modified in transit. —APNIC

Will Windows 10-on-ARM PCs support Mixed Reality headsets?

A Windows-on-ARM PC is getting closer to reality. Microsoft showed off a prototype mini-desktop with an ARM processor running Windows 10 at last week's Build conference, with the PC running applications like Office.The PC was shown in a video posted on the Channel 9 website. The presenters reinforced Microsoft's previous message saying that all x86 applications will work on Windows-on-ARM PCs.Microsoft has maintained that the experience on Windows 10-on-ARM PCs will be similar to x86 laptops, but many questions remain. One revolves around whether Windows 10-on-ARM PCs will support Windows Mixed Reality headsets.To read this article in full or to leave a comment, please click here

Reporters dox WannaCry ransomware kill switch guy

It is sickening when people prove “no good deed goes unpunished” to be true. I’m looking at you, British tabloids, because it was mean, stupid and very irresponsible to dox the guy who discovered the first WannaCry ransomware kill switch and thereby stopped thousands of old Windows machines from becoming infected.He goes by MalwareTech on Twitter and has an avatar of a cat wearing sunglasses. If he wanted to use his real name and picture, then he would have. Clearly, he values privacy and tries to maintain at least some degree of anonymity.Yet after being hailed as a hero for discovering a kill switch as WannaCry ransomware swept across globe, shady journalists doxed him. They dug into everything they could find online about MalwareTech, including trying to pry information from his friends.To read this article in full or to leave a comment, please click here
