Crypto-Ransomware : Your Feared Information Technology Catastrophe
Crypto-Ransomware  Remediation ExpertsCrypto-Ransomware has become a too-frequent cyber pandemic that poses an existential danger for organizations poorly prepared for an attack. Different versions of ransomware such as Reveton, WannaCry, Bad Rabbit, SamSam and MongoLock cryptoworms have been replicating for a long time and continue to inflict destruction. Newer variants of ransomware like Ryuk, Maze, Sodinokibi, DopplePaymer, Snatch and Nephilim, as well as additional as yet unnamed viruses, not only encrypt online information but also infiltrate many configured system backup. Information synched to the cloud can also be corrupted. In a vulnerable system, it can render automated restoration impossible and effectively knocks the network back to zero.

Getting back on-line services and data following a ransomware intrusion becomes a race against the clock as the targeted business tries its best to stop lateral movement, remove the ransomware, and resume business-critical activity. Because ransomware takes time to spread across a network, attacks are often sprung during nights and weekends, when penetrations typically take longer to identify. This compounds the difficulty of quickly assembling and orchestrating an experienced response team.

Progent offers an assortment of solutions for securing Cheyenne enterprises from ransomware events. These include user training to help identify and not fall victim to phishing attempts, ProSight Active Security Monitoring for endpoint detection and response (EDR) using SentinelOne's AI-based cyberthreat defense to identify and suppress day-zero malware attacks. Progent in addition offers the assistance of veteran crypto-ransomware recovery engineers with the track record and perseverance to reconstruct a breached system as urgently as possible.

Progent's Ransomware Restoration Support Services
Following a ransomware penetration, sending the ransom in cryptocurrency does not provide any assurance that criminal gangs will provide the keys to decipher any or all of your data. Kaspersky Labs estimated that 17% of ransomware victims never recovered their data after having sent off the ransom, resulting in additional losses. The risk is also expensive. Ryuk ransoms are typically several hundred thousand dollars. For larger organizations, the ransom can reach millions. The fallback is to setup from scratch the key parts of your IT environment. Without the availability of complete information backups, this requires a broad range of skills, top notch project management, and the willingness to work non-stop until the recovery project is completed.

For decades, Progent has provided certified expert Information Technology services for companies throughout the U.S. and has earned Microsoft's Partnership certification status in the Datacenter and Cloud Productivity competencies. Progent's pool of subject matter experts includes consultants who have attained top certifications in foundation technologies like Microsoft, Cisco, VMware, and major distributions of Linux.

This breadth of expertise affords Progent the capability to efficiently understand necessary systems and re-organize the remaining parts of your computer network system after a ransomware penetration and rebuild them into a functioning system.

Progent's recovery group has state-of-the-art project management systems to coordinate the sophisticated restoration process. Progent knows the urgency of working swiftly and together with a client's management and IT staff to prioritize tasks and to put essential systems back on line as soon as possible.

Business Case Study: A Successful Ransomware Penetration Recovery
A client contacted Progent after their network system was attacked by Ryuk ransomware virus. Ryuk is thought to have been deployed by North Korean state sponsored hackers, suspected of adopting techniques exposed from America's National Security Agency. Ryuk seeks specific organizations with limited room for operational disruption and is among the most lucrative examples of ransomware malware. High publicized targets include Data Resolution, a California-based info warehousing and cloud computing company, and the Chicago Tribune. Progent's client is a regional manufacturing business headquartered in Chicago with about 500 employees. The Ryuk event had shut down all essential operations and manufacturing processes. The majority of the client's information backups had been on-line at the start of the attack and were encrypted. The client was actively seeking loans for paying the ransom demand (in excess of two hundred thousand dollars) and wishfully thinking for good luck, but ultimately called Progent.


"I can't say enough in regards to the help Progent gave us during the most fearful period of (our) company's life. We most likely would have paid the cybercriminals if it wasn't for the confidence the Progent team provided us. That you could get our messaging and production applications back on-line quicker than 1 week was something I thought impossible. Each expert I got help from or communicated with at Progent was absolutely committed on getting us restored and was working day and night to bail us out."

Progent worked hand in hand the client to quickly determine and assign priority to the most important elements that had to be restored to make it possible to restart company functions:

  • Active Directory
  • Microsoft Exchange Email
  • Accounting/MRP
To start, Progent followed ransomware penetration response best practices by stopping the spread and cleaning systems of viruses. Progent then started the steps of restoring Microsoft Active Directory, the foundation of enterprise networks built upon Microsoft Windows technology. Microsoft Exchange email will not work without Windows AD, and the customer's accounting and MRP system utilized SQL Server, which needs Active Directory services for authentication to the information.

In less than 48 hours, Progent was able to rebuild Windows Active Directory to its pre-attack state. Progent then helped perform rebuilding and storage recovery on needed systems. All Microsoft Exchange Server data and configuration information were usable, which facilitated the rebuild of Exchange. Progent was able to collect non-encrypted OST data files (Outlook Off-Line Data Files) on various desktop computers and laptops in order to recover email messages. A not too old off-line backup of the client's accounting/MRP systems made it possible to return these essential applications back available to users. Although a lot of work still had to be done to recover completely from the Ryuk virus, critical services were recovered quickly:


"For the most part, the manufacturing operation never missed a beat and we did not miss any customer shipments."

During the following couple of weeks critical milestones in the restoration project were made through close collaboration between Progent team members and the customer:

  • Internal web applications were restored without losing any data.
  • The MailStore Server with over four million historical messages was brought on-line and accessible to users.
  • CRM/Product Ordering/Invoices/Accounts Payable/AR/Inventory modules were fully restored.
  • A new Palo Alto Networks 850 security appliance was set up and programmed.
  • 90% of the user workstations were back into operation.

"A lot of what occurred in the initial days is nearly entirely a fog for me, but our team will not forget the care all of your team put in to give us our business back. I have trusted Progent for the past 10 years, possibly more, and every time Progent has come through and delivered. This time was a life saver."

Conclusion
A potential business-killing catastrophe was avoided due to hard-working professionals, a wide range of IT skills, and tight collaboration. Although in retrospect the crypto-ransomware virus penetration described here could have been prevented with advanced security technology and security best practices, user education, and appropriate security procedures for data backup and proper patching controls, the reality is that government-sponsored hackers from China, North Korea and elsewhere are relentless and are an ongoing threat. If you do fall victim to a crypto-ransomware virus, feel confident that Progent's team of experts has substantial experience in ransomware virus defense, removal, and data restoration.


"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others that were helping), thanks very much for making it so I could get some sleep after we got through the initial fire. All of you did an incredible effort, and if anyone is around the Chicago area, a great meal is my treat!"
