Ransomware : Your Feared Information Technology Catastrophe
Ransomware has become a modern cyber pandemic that poses an existential threat for businesses of all sizes vulnerable to an assault. Versions of ransomware like the CryptoLocker, WannaCry, Locky, NotPetya and MongoLock cryptoworms have been running rampant for many years and still inflict harm. The latest strains of ransomware like Ryuk, Maze, Sodinokibi, Netwalker, Lockbit or Egregor, plus more as yet unnamed malware, not only do encryption of on-line information but also infect any configured system restores and backups. Files replicated to off-site disaster recovery sites can also be ransomed. In a poorly designed system, this can make automatic recovery useless and effectively sets the network back to zero.
Getting back online applications and information after a ransomware intrusion becomes a sprint against the clock as the targeted business tries its best to stop the spread and cleanup the crypto-ransomware and to resume business-critical activity. Since ransomware takes time to spread, assaults are frequently launched during nights and weekends, when successful penetrations tend to take longer to recognize. This compounds the difficulty of quickly mobilizing and organizing a qualified mitigation team.
Progent provides a range of support services for securing businesses from ransomware attacks. These include team education to help identify and avoid phishing attempts, ProSight Active Security Monitoring (ASM) for remote monitoring and management, plus setup and configuration of the latest generation security gateways with machine learning capabilities to rapidly detect and quarantine day-zero threats. Progent in addition can provide the assistance of expert ransomware recovery professionals with the talent and commitment to restore a compromised network as urgently as possible.
Progent's Crypto-Ransomware Restoration Help
Soon after a crypto-ransomware penetration, sending the ransom in cryptocurrency does not ensure that criminal gangs will respond with the needed codes to decrypt any of your information. Kaspersky Labs determined that seventeen percent of ransomware victims never recovered their information after having paid the ransom, resulting in more losses. The risk is also expensive. Ryuk ransoms often range from 15-40 BTC ($120,000 and $400,000). This is well above the typical ransomware demands, which ZDNET estimates to be approximately $13,000. The other path is to piece back together the mission-critical elements of your Information Technology environment. Absent the availability of full information backups, this requires a broad complement of skill sets, well-coordinated project management, and the ability to work non-stop until the recovery project is finished.

Client Case Study: A Successful Ransomware Incident Response
A small business contacted Progent after their organization was taken over by Ryuk ransomware. Ryuk is believed to have been developed by North Korean government sponsored cybercriminals, possibly adopting approaches exposed from the United States National Security Agency. Ryuk targets specific businesses with little room for operational disruption and is among the most lucrative iterations of ransomware malware. Well Known victims include Data Resolution, a California-based data warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a small manufacturing business located in the Chicago metro area with about 500 employees. The Ryuk intrusion had disabled all essential operations and manufacturing processes. Most of the client's system backups had been directly accessible at the beginning of the attack and were destroyed. The client was actively seeking loans for paying the ransom (exceeding $200K) and hoping for the best, but ultimately made the decision to use Progent.
"I cannot speak enough in regards to the support Progent provided us throughout the most critical time of (our) companyís survival. We most likely would have paid the Hackers except for the confidence the Progent experts afforded us. The fact that you were able to get our e-mail and production servers back in less than 1 week was something I thought impossible. Every single person I got help from or texted at Progent was amazingly focused on getting our system up and was working all day and night on our behalf."
Progent worked hand in hand the client to rapidly identify and assign priority to the critical systems that needed to be recovered to make it possible to restart business functions:
To start, Progent followed AV/Malware Processes event mitigation best practices by halting lateral movement and clearing up compromised systems. Progent then started the process of bringing back online Windows Active Directory, the foundation of enterprise networks built upon Microsoft Windows Server technology. Exchange messaging will not work without AD, and the businessesí accounting and MRP system utilized SQL Server, which requires Windows AD for security authorization to the information.
- Windows Active Directory
- Electronic Mail
- Accounting and Manufacturing Software
Within 48 hours, Progent was able to recover Windows Active Directory to its pre-attack state. Progent then charged ahead with reinstallations and hard drive recovery on mission critical applications. All Exchange schema and configuration information were usable, which facilitated the rebuild of Exchange. Progent was also able to locate intact OST files (Outlook Email Off-Line Data Files) on team PCs to recover email data. A recent off-line backup of the client's manufacturing software made it possible to return these essential services back online for users. Although a large amount of work needed to be completed to recover fully from the Ryuk event, essential systems were recovered quickly:
"For the most part, the production operation ran fairly normal throughout and we delivered all customer sales."
During the next month critical milestones in the restoration process were achieved in close collaboration between Progent consultants and the customer:
- In-house web applications were returned to operation without losing any information.
- The MailStore Server containing more than four million historical emails was brought online and accessible to users.
- CRM/Orders/Invoicing/Accounts Payable/Accounts Receivables/Inventory Control modules were 100% operational.
- A new Palo Alto 850 firewall was installed and configured.
- Ninety percent of the user PCs were fully operational.
"A lot of what went on that first week is mostly a blur for me, but our team will not forget the commitment all of your team put in to help get our business back. I have entrusted Progent for the past ten years, maybe more, and every time Progent has come through and delivered as promised. This event was a stunning achievement."
A possible business extinction catastrophe was evaded with dedicated professionals, a wide range of knowledge, and tight teamwork. Although in retrospect the ransomware incident described here would have been stopped with current cyber security systems and ISO/IEC 27001 best practices, user training, and well designed security procedures for information protection and keeping systems up to date with security patches, the reality remains that government-sponsored criminal cyber gangs from Russia, China and elsewhere are tireless and will continue. If you do get hit by a ransomware penetration, feel confident that Progent's roster of experts has substantial experience in crypto-ransomware virus blocking, remediation, and data recovery.
"So, to Darrin, Matt, Aaron, Dan, Jesse, Arnaud, Allen, Tony and Chris (along with others who were helping), thanks very much for making it so I could get some sleep after we made it over the first week. All of you did an incredible job, and if any of your guys is around the Chicago area, dinner is my treat!"
