Ransomware : Your Crippling IT Nightmare
Crypto-Ransomware  Remediation ProfessionalsCrypto-Ransomware has become a too-frequent cyber pandemic that represents an extinction-level danger for organizations vulnerable to an attack. Different iterations of crypto-ransomware such as Reveton, WannaCry, Bad Rabbit, NotPetya and MongoLock cryptoworms have been running rampant for a long time and still inflict destruction. Newer strains of ransomware like Ryuk, Maze, Sodinokibi, Netwalker, LockBit and Egregor, along with frequent as yet unnamed viruses, not only encrypt online critical data but also infect any accessible system restores and backups. Information synchronized to cloud environments can also be corrupted. In a poorly architected data protection solution, this can render automated restoration useless and effectively knocks the entire system back to square one.

Getting back programs and information following a ransomware intrusion becomes a sprint against the clock as the victim fights to stop lateral movement, cleanup the virus, and resume enterprise-critical operations. Since ransomware requires time to move laterally across a targeted network, attacks are usually launched during nights and weekends, when successful penetrations tend to take longer to notice. This multiplies the difficulty of rapidly mobilizing and organizing a qualified mitigation team.

Progent provides a range of services for protecting Dallas enterprises from ransomware penetrations. Among these are team member training to help recognize and not fall victim to phishing attempts, ProSight Active Security Monitoring (ASM) for endpoint detection and response (EDR) using SentinelOne's behavior-based cyberthreat defense to identify and quarantine day-zero modern malware assaults. Progent in addition offers the assistance of expert crypto-ransomware recovery engineers with the track record and commitment to reconstruct a compromised network as rapidly as possible.

Progent's Crypto-Ransomware Restoration Support Services
After a ransomware penetration, sending the ransom demands in cryptocurrency does not guarantee that merciless criminals will respond with the keys to unencrypt all your information. Kaspersky determined that 17% of crypto-ransomware victims never restored their data even after having paid the ransom, resulting in additional losses. The gamble is also costly. Ryuk ransoms are often a few hundred thousand dollars. For larger enterprises, the ransom can reach millions. The fallback is to piece back together the key components of your Information Technology environment. Without access to essential data backups, this calls for a wide range of skill sets, professional project management, and the capability to work continuously until the task is completed.

Customer Case Study: A Successful Crypto-Ransomware Intrusion Recovery
A client sought out Progent after their company was taken over by Ryuk crypto-ransomware. Ryuk is thought to have been deployed by North Korean state sponsored hackers, possibly using algorithms leaked from the U.S. National Security Agency. Ryuk seeks specific organizations with limited ability to sustain operational disruption and is one of the most lucrative iterations of ransomware. Well Known targets include Data Resolution, a California-based information warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a regional manufacturer headquartered in Chicago and has about 500 workers. The Ryuk intrusion had brought down all business operations and manufacturing capabilities. The majority of the client's backups had been online at the beginning of the intrusion and were damaged. The client was pursuing financing for paying the ransom demand (exceeding two hundred thousand dollars) and hoping for good luck, but in the end made the decision to use Progent.


"I cannot tell you enough in regards to the expertise Progent provided us during the most critical time of (our) businesses survival. We had little choice but to pay the cyber criminals if not for the confidence the Progent experts provided us. That you could get our e-mail and essential applications back faster than one week was incredible. Each staff member I talked with or texted at Progent was urgently focused on getting us back online and was working breakneck pace on our behalf."

Progent worked together with the customer to rapidly determine and prioritize the most important systems that needed to be addressed to make it possible to resume business operations:

  • Active Directory (AD)
  • Microsoft Exchange Server
  • MRP System
To begin, Progent adhered to AV/Malware Processes penetration mitigation industry best practices by stopping the spread and clearing up compromised systems. Progent then started the steps of recovering Active Directory, the heart of enterprise networks built upon Microsoft technology. Microsoft Exchange email will not work without Windows AD, and the customer's MRP system used Microsoft SQL, which depends on Active Directory for access to the data.

In less than 2 days, Progent was able to rebuild Active Directory to its pre-virus state. Progent then assisted with reinstallations and storage recovery on needed systems. All Microsoft Exchange Server schema and attributes were usable, which greatly helped the restore of Exchange. Progent was also able to locate intact OST files (Outlook Offline Data Files) on various workstations and laptops to recover email information. A recent off-line backup of the customer's financials/ERP software made it possible to recover these vital applications back servicing users. Although a large amount of work still had to be done to recover totally from the Ryuk virus, the most important systems were returned to operations rapidly:


"For the most part, the production line operation survived unscathed and we delivered all customer orders."

Throughout the next couple of weeks important milestones in the recovery project were achieved through tight collaboration between Progent engineers and the client:

  • Self-hosted web applications were restored with no loss of data.
  • The MailStore Exchange Server containing more than 4 million historical emails was brought on-line and available for users.
  • CRM/Orders/Invoicing/AP/Accounts Receivables (AR)/Inventory Control modules were 100% functional.
  • A new Palo Alto Networks 850 firewall was brought on-line.
  • Most of the desktops and laptops were functioning as before the incident.

"Much of what went on those first few days is nearly entirely a haze for me, but I will not forget the countless hours each of the team accomplished to give us our company back. I have trusted Progent for at least 10 years, maybe more, and each time Progent has impressed me and delivered as promised. This event was a stunning achievement."

Conclusion
A potential business-killing catastrophe was evaded with dedicated professionals, a broad range of subject matter expertise, and tight collaboration. Although in post mortem the ransomware virus attack described here could have been prevented with up-to-date cyber security technology and NIST Cybersecurity Framework best practices, team education, and well thought out incident response procedures for information backup and applying software patches, the fact is that government-sponsored cyber criminals from Russia, North Korea and elsewhere are tireless and are not going away. If you do get hit by a ransomware attack, remember that Progent's roster of professionals has substantial experience in ransomware virus defense, mitigation, and data recovery.


"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (and any others who were involved), I'm grateful for making it so I could get rested after we got over the first week. Everyone did an fabulous effort, and if any of your team is around the Chicago area, a great meal is my treat!"
