Crypto-Ransomware : Your Worst Information Technology Disaster
Ransomware has become a too-frequent cyberplague that presents an existential danger for businesses of all sizes unprepared for an attack. Different iterations of ransomware like the CryptoLocker, CryptoWall, Bad Rabbit, SamSam and MongoLock cryptoworms have been circulating for years and still cause harm. The latest strains of ransomware like Ryuk, Maze, Sodinokibi, Netwalker, Conti or Nephilim, along with more unnamed malware, not only encrypt on-line critical data but also infiltrate most configured system restores and backups. Files synchronized to off-site disaster recovery sites can also be ransomed. In a poorly architected system, it can make automated restore operations useless and effectively sets the datacenter back to square one.
Retrieving applications and information after a ransomware attack becomes a race against the clock as the targeted business struggles to stop lateral movement and cleanup the ransomware and to restore enterprise-critical activity. Since ransomware requires time to replicate, penetrations are usually sprung on weekends and holidays, when penetrations in many cases take longer to detect. This multiplies the difficulty of quickly marshalling and coordinating a knowledgeable response team.
Progent offers a range of services for securing enterprises from ransomware penetrations. These include team education to become familiar with and avoid phishing exploits, ProSight Active Security Monitoring (ASM) for remote monitoring and management, along with installation of the latest generation security gateways with machine learning capabilities to rapidly identify and extinguish new cyber attacks. Progent also offers the services of seasoned ransomware recovery consultants with the skills and commitment to restore a compromised network as urgently as possible.
Progent's Ransomware Restoration Services
After a crypto-ransomware penetration, even paying the ransom in Bitcoin cryptocurrency does not provide any assurance that cyber criminals will respond with the keys to decipher any of your files. Kaspersky Labs estimated that 17% of ransomware victims never restored their data after having paid the ransom, resulting in more losses. The risk is also costly. Ryuk ransoms commonly range from fifteen to forty BTC ($120,000 and $400,000). This is significantly higher than the average ransomware demands, which ZDNET averages to be around $13,000. The alternative is to piece back together the critical components of your Information Technology environment. Absent access to essential information backups, this requires a broad complement of skills, professional project management, and the ability to work 24x7 until the recovery project is complete.

Progent appreciates the importance of working swiftly and together with a client's management and Information Technology resources to prioritize tasks and to get critical applications back on-line as fast as humanly possible.
Client Case Study: A Successful Ransomware Incident Recovery
A small business escalated to Progent after their organization was attacked by Ryuk ransomware. Ryuk is believed to have been launched by Northern Korean state cybercriminals, suspected of adopting approaches exposed from the United States National Security Agency. Ryuk seeks specific companies with limited room for operational disruption and is among the most lucrative instances 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 single-location manufacturing company located in the Chicago metro area and has around 500 workers. The Ryuk intrusion had shut down all company operations and manufacturing capabilities. The majority of the client's backups had been online at the start of the intrusion and were destroyed. The client considered paying the ransom (exceeding two hundred thousand dollars) and praying for good luck, but ultimately brought in Progent.
"I cannot thank you enough about the support Progent gave us throughout the most critical time of (our) businesses existence. We most likely would have paid the cyber criminals behind the attack if not for the confidence the Progent team afforded us. The fact that you could get our e-mail system and key servers back on-line quicker than 1 week was beyond my wildest dreams. Each person I spoke to or communicated with at Progent was amazingly focused on getting our system up and was working breakneck pace on our behalf."
Progent worked together with the customer to quickly assess and prioritize the essential elements that needed to be addressed to make it possible to restart business functions:
To get going, Progent followed Anti-virus event mitigation best practices by isolating and cleaning up infected systems. Progent then began the work of recovering Active Directory, the foundation of enterprise systems built on Microsoft technology. Microsoft Exchange messaging will not operate without Windows AD, and the client's MRP software used Microsoft SQL, which depends on Active Directory services for authentication to the database.
- Active Directory
- Exchange Server
In less than 48 hours, Progent was able to re-build Active Directory services to its pre-virus state. Progent then completed setup and hard drive recovery of critical systems. All Microsoft Exchange Server ties and configuration information were intact, which accelerated the restore of Exchange. Progent was able to locate non-encrypted OST data files (Outlook Email Off-Line Data Files) on various workstations and laptops in order to recover email information. A recent offline backup of the customerís accounting/MRP systems made them able to return these essential applications back online for users. Although a large amount of work remained to recover totally from the Ryuk event, critical systems were recovered quickly:
"For the most part, the assembly line operation never missed a beat and we did not miss any customer sales."
Throughout the following month critical milestones in the recovery project were made in close collaboration between Progent team members and the customer:
- In-house web sites were returned to operation without losing any information.
- The MailStore Microsoft Exchange Server exceeding four million archived messages was brought online and accessible to users.
- CRM/Orders/Invoicing/Accounts Payable (AP)/AR/Inventory Control functions were 100% recovered.
- A new Palo Alto Networks 850 security appliance was brought on-line.
- Most of the user desktops were back into operation.
"Much of what occurred in the early hours is nearly entirely a haze for me, but our team will not soon forget the care each of your team accomplished to help get our business back. Iíve trusted Progent for the past ten years, maybe more, and every time Progent has outperformed my expectations and delivered. This time was the most impressive ever."
A probable enterprise-killing disaster was dodged with dedicated professionals, a broad range of IT skills, and close teamwork. Although in retrospect the ransomware virus attack detailed here could have been identified and blocked with up-to-date security technology solutions and best practices, user and IT administrator training, and properly executed incident response procedures for information backup and proper patching controls, the reality is that state-sponsored hackers from Russia, North Korea and elsewhere are relentless and are not going away. If you do get hit by a ransomware incursion, feel confident that Progent's team of professionals has substantial experience in crypto-ransomware virus defense, remediation, and file recovery.
"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (and any others who were helping), thanks very much for letting me get some sleep after we got over the initial fire. Everyone did an fabulous effort, and if any of your guys is in the Chicago area, dinner is on me!"
