Crypto-Ransomware : Your Worst Information Technology Disaster
Ransomware has become an escalating cyberplague that presents an enterprise-level threat for organizations vulnerable to an assault. Different versions of ransomware such as CrySIS, WannaCry, Locky, NotPetya and MongoLock cryptoworms have been circulating for many years and continue to cause destruction. More recent variants of ransomware such as Ryuk and Hermes, as well as daily as yet unnamed viruses, not only do encryption of online data files but also infect most configured system restores and backups. Information synchronized to cloud environments can also be encrypted. In a poorly designed environment, it can make automatic restoration useless and effectively knocks the network back to square one.
Getting back online services and data following a crypto-ransomware attack becomes a sprint against the clock as the targeted business fights to stop lateral movement and clear the ransomware and to resume mission-critical operations. Since ransomware requires time to move laterally, attacks are often launched during weekends and nights, when successful penetrations in many cases take longer to uncover. This compounds the difficulty of quickly assembling and coordinating a knowledgeable mitigation team.
Progent offers an assortment of support services for securing enterprises from crypto-ransomware events. Among these are team education to help identify and not fall victim to phishing exploits, ProSight Active Security Monitoring for remote monitoring and management, along with deployment of modern security appliances with AI capabilities to rapidly detect and quarantine zero-day cyber attacks. Progent also provides the services of expert ransomware recovery engineers with the track record and perseverance to reconstruct a breached network as quickly as possible.
Progent's Ransomware Restoration Support Services
After a ransomware attack, paying the ransom demands in cryptocurrency does not ensure that distant criminals will respond with the needed keys to decipher any of your information. Kaspersky Labs estimated that seventeen percent of ransomware victims never restored their information after having sent off the ransom, resulting in increased losses. The gamble is also very costly. Ryuk ransoms frequently range from 15-40 BTC ($120,000 and $400,000). This is significantly higher than the average crypto-ransomware demands, which ZDNET averages to be approximately $13,000. The other path is to re-install the key parts of your Information Technology environment. Without access to essential system backups, this requires a wide range of skill sets, top notch team management, and the capability to work 24x7 until the task is done.

Client Case Study: A Successful Crypto-Ransomware Incident Response
A client engaged Progent after their network was taken over by the Ryuk crypto-ransomware. Ryuk is thought to have been launched by Northern Korean state cybercriminals, possibly using algorithms leaked from the U.S. NSA organization. Ryuk goes after specific businesses with little ability to sustain disruption and is among the most profitable versions of ransomware viruses. Well Known targets include Data Resolution, a California-based information warehousing and cloud computing business, and the Chicago Tribune. Progent's client is a single-location manufacturing business headquartered in Chicago and has about 500 staff members. The Ryuk event had shut down all company operations and manufacturing processes. The majority of the client's information backups had been online at the start of the attack and were destroyed. The client considered paying the ransom (in excess of $200K) and praying for good luck, but ultimately called Progent.
"I cannot speak enough about the care Progent gave us throughout the most stressful time of (our) businesses survival. We had little choice but to pay the cyber criminals if not for the confidence the Progent team afforded us. The fact that you could get our e-mail system and important applications back into operation quicker than seven days was amazing. Every single person I worked with or communicated with at Progent was absolutely committed on getting our system up and was working 24/7 to bail us out."
Progent worked with the customer to rapidly identify and assign priority to the key systems that needed to be restored to make it possible to resume business operations:
To begin, Progent followed ransomware penetration mitigation industry best practices by isolating and cleaning systems of viruses. Progent then started the process of recovering Windows Active Directory, the heart of enterprise environments built on Microsoft technology. Microsoft Exchange messaging will not work without Active Directory, and the customerís MRP applications used Microsoft SQL Server, which requires Active Directory services for access to the databases.
- Active Directory
- Exchange Server
- MRP System
Within 2 days, Progent was able to restore Active Directory to its pre-intrusion state. Progent then accomplished rebuilding and storage recovery of key servers. All Microsoft Exchange Server ties and attributes were usable, which facilitated the rebuild of Exchange. Progent was also able to find local OST files (Microsoft Outlook Off-Line Folder Files) on various workstations to recover mail information. A not too old offline backup of the customerís accounting software made them able to recover these required services back available to users. Although significant work needed to be completed to recover fully from the Ryuk virus, the most important systems were recovered rapidly:
"For the most part, the production operation was never shut down and we made all customer shipments."
Throughout the next couple of weeks important milestones in the recovery process were accomplished in tight collaboration between Progent team members and the customer:
- In-house web sites were restored with no loss of information.
- The MailStore Exchange Server with over four million archived emails was restored to operations and accessible to users.
- CRM/Product Ordering/Invoices/AP/Accounts Receivables/Inventory modules were 100% functional.
- A new Palo Alto Networks 850 security appliance was brought online.
- Most of the user PCs were operational.
"A huge amount of what happened in the initial days is nearly entirely a blur for me, but our team will not soon forget the dedication all of the team put in to give us our company back. I have trusted Progent for at least 10 years, maybe more, and each time I needed help Progent has outperformed my expectations and delivered as promised. This situation was a Herculean accomplishment."
A likely enterprise-killing disaster was avoided with hard-working experts, a wide spectrum of IT skills, and tight teamwork. Although upon completion of forensics the ransomware incident detailed here could have been blocked with current cyber security technology and security best practices, staff training, and appropriate incident response procedures for backup and proper patching controls, the reality remains that state-sponsored cyber criminals from Russia, North Korea and elsewhere are tireless and are an ongoing threat. If you do get hit by a ransomware incident, remember that Progent's team of experts has substantial experience in ransomware virus defense, removal, and file recovery.
"So, to Darrin, Matt, Aaron, Claude, Jesse, Arnaud, Allen, Tony and Chris (and any others who were helping), Iím grateful for allowing me to get some sleep after we made it past the initial fire. Everyone did an impressive job, and if any of your guys is visiting the Chicago area, dinner is the least I can do!"
