This morning started off with a major setback when I discovered that my virtual machines on my remote ESXi server had been compromised by hackers who likely gained access through RDP due to weak passwords. While I have backups for my programs, restoring my VMs will take up valuable time that I simply cannot spare. Do you have any advice on how to quickly and securely recover from a cyber attack on virtual machines like mine?

It is important to stay vigilant, as ransomware can lie dormant for long periods before being triggered. This was a lesson learned by one of my previous clients, whose backups were also compromised due to the delay in detection. It is crucial to have a reliable backup strategy in place to protect against such threats.
I concur with Ken's perspective that everything must be treated as suspect now. It is crucial to conduct a thorough wipe and rebuild of any systems that the virtual machines (VMs) could have potentially touched on the network. There should be no reliance on saved data or backups in this situation. If the VMs were not accessible via the internet, it is likely that the intrusion occurred through another entry point. It is imperative to prioritize security measures in light of this breach.
How much ransom are they asking for? I wouldn't consider paying as my time is valuable, but it's always an option. In the past, I was the go-to person for recovering computers from ransomware attacks for friends and family. However, it's been a while and the tools and methods have changed, so I may not be up to date. The first step in dealing with ransomware is to identify the specific type you are dealing with. Search for "how to identify ransomware" to find useful information. If you are fortunate, there may be a decryption tool available for free. Be cautious of purchasing decryption tools from unknown sources. In the past, I used Avast for cleaning infected computers due to its efficient boot time scan feature. However, it has been some time since I last used it. At this point, it's important to treat everything on the infected machine as suspect. Even after cleaning it up, there may still be hidden threats like backdoors or keyloggers. Personally, I would recommend starting fresh and not taking any risks. Moving forward, consider using a password manager like Keepass to enhance your online security. It's a reliable tool that can help you manage passwords securely. Remember to start fresh on any new, clean devices to ensure your safety online.
How can I verify this? The first thing I did this morning was to check if the VMs had rebooted, and I noticed that some of the files now have a .hazard12 extension. I then checked Windows update and saw that there was a Windows 10 update on the 30th. This morning, I was able to create "fresh" backups from InTouch, and it seems that the Rockwell *.ACD files were not affected. I scanned them with Defender, but I am unsure if it is safe to move them without causing any damage.
I'm sorry to hear about this setback—it's a real headache when something like this happens. To recover swiftly, I would suggest using a full VM restore from your most recent backup, an effective and often quick method to return to pre-attack conditions. For security purposes, however, immediately avoid using weak RDP passwords. Instead, consider implementing two-factor authentication and ensure all your software patches are up to date. Moreover, limiting RDP access to specific IPs and employing intrusion detection systems might be useful in preventing future attacks. Remember, as much as we are concerned about recovery, prevention is equally critical.
Absolutely sorry to hear about your situation. First off, it's paramount to disable the compromised RDP access and change all your passwords. Use strong and unique passwords, and consider enabling two-factor authentication, if possible. To speed up the recovery process, make use of your backup images and prioritize restoring the most essential services first. Moving forward, consider employing more robust security measures like firewall configurations, intrusion detection systems, or professional managed security services to handle cyber threats. In addition, regularly updating and patching software is key to deter potential vulnerabilities that hackers can exploit.
Really sorry to hear about your predicament. While recovering, consider implementing multi-factor authentication to fortify your security, and ensure your passwords are strong and unique. Deploying an Intrusion Detection System (IDS) on your network would also be beneficial in identifying and alerting you to suspicious activities in real time. To speed up recovery, you could possibly automate the restoration of your VMs from your backups if you haven't done so already. Lastly, think about getting a professional cybersecurity assessment to identify and rectify potential vulnerabilities. Stay safe!
I'm sorry to hear about the breach you've experienced - that's certainly a stressful situation. Thankfully, you do have backups, which means you won't lose your programs. As a tip, consider leveraging automation scripts like PowerShell for quicker restoration of your VMs in the future. Also, have a look at intrusion detection/prevention system (IDS/IPS) solutions that can add an extra layer of security to your ESXi server. And most importantly, try to enforce a stronger password policy, possibly enabling two-factor authentication, to eliminate the risk of another breach through RDP.
I'm really sorry to hear about your situation—that's incredibly frustrating. On top of restoring your VMs from backups, consider isolating the affected systems to prevent any further breaches, and take this opportunity to do a thorough security audit. Changing all passwords and possibly enabling two-factor authentication for remote access are essential steps. If time is tight, you might also think about using the VM snapshots if you have them, as they could speed up the recovery process. Lastly, once you're back up, implementing a stronger password policy and better firewall rules will help prevent future incidents. Hang in there!
I’m really sorry to hear about your situation, that sounds incredibly frustrating! Quick recovery can be tricky, but here are a few steps that might help: first, if you haven’t already, isolate the affected VMs to prevent further spreading of the breach. Then, assess your backups and prioritize restoring only the most critical VMs first to get your operations back up. Consider using a clean recovery environment to ensure you’re not reintroducing the same vulnerabilities. Lastly, once you've got things running again, it's also a good time to implement stronger security measures—like multi-factor authentication and better password policies—to prevent this from happening in the future. Good luck!
