My Sunday morning was muddled 2 weeks ago. There was a frenetic call from someone whom I knew a while back and he needed some advice. Turned out that his company’s files were encrypted and the “backups” (more on this later) were gone. With some detective work, I found that their files were stored in a Synology® NAS, often accessed via QuickConnect remotely, and “backed up” to Microsoft® Azure. I put “Backup” in inverted commas because their definition of “backup” was using Synology®’s Cloud Sync to Azure. It is not a true backup but a file synchronization service that often mislabeled as a data protection backup service.
All of his company’s projects files were encrypted and there were no backups to recover from. It was a typical ransomware cluster F crime scene.
I would have gloated because many of small medium businesses like his take a very poor and lackadaisical attitude towards good data management practices. No use crying over spilled milk when prevention is better than cure. But instead of investing early in the prevention, the cure would likely be 3x more expensive. And in this case, he wanted to use Deloitte® recovery services, which I did not know existed. Good luck with the recovery was all I said to him after my Sunday morning was made topsy turvy of sorts.
NAS is the ransomware goldmine
I have said it before and I am saying it again. NAS devices, especially the consumer and prosumer brands, are easy pickings because there was little attention paid to implement a good data management practice either by the respective vendor or the end users themselves. 2 years ago I was already seeing a consistent pattern of the heightened ransomware attacks on NAS devices, especially the NAS devices that proliferated the small medium businesses market segment.
The WFH (work from home) practice trigged by the Covid-19 pandemic has made NAS devices essential for businesses. NAS are the workhorses of many businesses after all. The ease of connecting from anywhere with features similar to the Synology® QuickConnect I mentioned earlier, or through VPNs (virtual private networks), or a self created port forwarding (for those who wants to save a quick buck [ sarcasm ]), opened the doors to bad actors and easy ransomware incursions. Good data management practices are often sidestepped or ignored in exchange for simplicity, convenience, and trying to save foolish dollars.Until ….
The Enterprise File Sync and Share (EFSS) EasiShare presence is growing rapidly in the region, as enterprises and organizations are quickly redefining the boundaries of the new workspace. Work files and folders are no longer confined to the shared network drives within the local area network. It is going beyond to the “Work from Anywhere” phenomenon that is quickly becoming the way of life. Breaking away from the usual IT security protection creates a new challenge, but EasiShare was conceived with security baked into its DNA. With the recent release, Version 10, file sharing security and resiliency are stronger than ever.
[ Note: I have blogged about EasiShare previously. Check out the 2 links below ]
Public clouds are the obvious choice but for organizations to protect their work files, and keep data secure, services like Dropbox for Business, Microsoft® Office 365 with OneDrive and Google® Workspace are not exactly the kind of file sharing with security as their top priority. A case in point was the 13-hour disruption to Wasabi Cloud last week, where the public cloud storage provider’s domain name, wasabisys.com, was suspended by their domain name registrar because of malware discrepancy at one of its endpoints. There were other high profile cases too.
This is where EasiShare shines, because it is a secure, private EFSS solution for the enterprise and beyond, because business resiliency is in the hands and control of the organization that owns it, not the public cloud service providers.
EasiShare unifies with TrueNAS for secure business resiliency
EasiShare is just one several key business solutions iXsystems™ in Asia Pacific Japan is working closely with, and there is a strong, symbiotic integration with the TrueNAS® platform. Both have strong security features that fortify business resiliency, especially when facing the rampant ransomware scourge.
Value of a Single Unified Data Services Platform
A storage array is not a solution. It is just a box that most vendors push to sell. A storage must be a Data Services Platform. Readers of my blog would know that I have spoken about the Data Services Platform 3 years ago and you can read about it:
I had a few “self assigned homework exercises” I have to do this weekend. I was planning to do a video webcast with an EFSS vendor soon, and the theme should be around ransomware. Then one of the iXsystems™ resellers, unrelated to the first exercise, was talking about this ransomware messaging yesterday after we did a technical training with them. And this weekend is coming on a bit light as well. So I thought I could bring all these things, including checking out the TrueNAS® CORE 12.0, together in a video (using Free Cam), of which I would do for the first time as well. WOW!I can kill 4 birds with one stone! All together in one blog!
It could be Adam Brown 89 or worse
Trust me. You do not want AdamBrown89 as your friend. Or his thousands of ransomware friends.
When (not if) you are infected by ransomware, you get a friendly message like this in the screenshot below. I got this from a local company who asked for my help a few months ago.
AdamBrown89 ransomware message
I have written about this before. NAS (Network Attached Storage) has become a gold mine for ransomware attackers, and many entry level NAS products are heavily inflicted with security flaws and vulnerabilities. Here are a few notable articles in year 2020 alone. [ Note: This has been my journal of the security flaws of NAS devices from 2020 onwards ]
Garmin paid, reportedly millions. Do you sleep well at night knowing that the scourge of ransomware is rampant and ever threatening your business. Is your storage safe enough or have you invested in a storage which was the economical (also to be known as cheap) to your pocket?
Garmin was hacked by ransomware
I have highlighted this before. NAS (Network Attached Storage) has become the goldmine for ransomware. And in the mire of this COVID-19 pandemic, the lackadaisical attitude of securing the NAS storage remains. Too often than not, end users and customers, especially in the small medium enterprises segment, continue to search for the most economical NAS storage to use in their business.
Is price the only factor?
Why do customers and end users like to look at the price? Is an economical capital outlay of a cheap NAS storage with 3-year hardware and shallow technical support that significant to appease the pocket gods? Some end users might decided to rent cloud file storage, Hotel California style until they counted the 3-year “rental” price.
Early in the year, I wrote about NAS systems being a high impact target for ransomware. I called NAS a goldmine for ransomware. This is still very true because NAS systems are the workhorses of many organizations. They serve files and folders and from it, the sharing and collaboration of Work.
Another common function for NAS systems is being a target for backups. In small medium organizations, backup software often direct their backups to a network drive in the network. Even for larger enterprise customers too, NAS is the common destination for backups.
Typical NAS backup for small medium organizations.
Backup to Data Domain with NAS (NFS, CIFS) Protocols
Ransomware is obviously targeting the backup as another high impact target, with the potential to disrupt the rescue and the restoration of the work files and folders.
It is from one of my FreeNAS customers daily security run logs, emailed to our email@example.com alias. It is attempting a brute force attack trying to crack the authentication barrier via the exposed SSH port.
Just days after the installation was completed months ago, a bot has been doing IP port scans on our system, and found the SSH port open. (We used it for remote support). It has been trying every since, and we have been observing the source IP addresses.
The new Ransomware attack vector
This is not surprising to me. Ransomware has become more sophisticated and more damaging than ever because the monetary returns from the ransomware are far more effective and lucrative than other cybersecurity threats so far. And the easiest preys are the weakest link in the People, Process and Technology chain. Phishing breaches through social engineering, emails are the most common attack vectors, but there are vhishing (via voicemail) and smshing (via SMS) out there too. Of course, we do not discount other attack vectors such as mal-advertising sites, or exploits and so on. Anything to deliver the ransomware payload.
