Ransomware : Your Crippling IT Catastrophe
Ransomware  Remediation ExpertsRansomware has become a modern cyber pandemic that presents an enterprise-level danger for businesses of all sizes poorly prepared for an assault. Versions of ransomware such as Reveton, CryptoWall, Bad Rabbit, Syskey and MongoLock cryptoworms have been running rampant for years and still inflict havoc. Modern variants of crypto-ransomware like Ryuk, Maze, Sodinokibi, DopplePaymer, LockBit and Egregor, as well as more as yet unnamed viruses, not only perform encryption of online information but also infiltrate most available system restores and backups. Data replicated to off-premises disaster recovery sites can also be corrupted. In a vulnerable environment, it can render automated recovery impossible and basically knocks the entire system back to square one.

Getting back services and data after a crypto-ransomware attack becomes a race against time as the targeted organization struggles to contain the damage, eradicate the crypto-ransomware, and resume mission-critical operations. Since ransomware requires time to move laterally across a network, assaults are frequently sprung during nights and weekends, when penetrations may take longer to uncover. This multiplies the difficulty of promptly marshalling and orchestrating a capable response team.

Progent provides an assortment of services for protecting Nashville businesses from ransomware attacks. These include user training to help identify and not fall victim to phishing scams, ProSight Active Security Monitoring for endpoint detection and response using SentinelOne's behavior-based threat defense to discover and quarantine day-zero malware attacks. Progent also provides the services of experienced crypto-ransomware recovery professionals with the skills and commitment to re-deploy a breached environment as rapidly as possible.

Progent's Crypto-Ransomware Restoration Support Services
Soon after a ransomware penetration, even paying the ransom in cryptocurrency does not guarantee that distant criminals will return the keys to decrypt any of your data. Kaspersky estimated that 17% of ransomware victims never recovered their data after having paid the ransom, resulting in additional losses. The risk is also costly. Ryuk ransoms are typically several hundred thousand dollars. For larger organizations, the ransom can reach millions. The fallback is to setup from scratch the essential parts of your IT environment. Without access to essential data backups, this requires a broad range of skills, professional team management, and the capability to work non-stop until the task is completed.

Progent understands the importance of acting quickly and in unison with a customer's management and Information Technology team members to assign priority to tasks and to get key services back on-line as fast as possible.

Customer Case Study: A Successful Ransomware Penetration Restoration
A business engaged Progent after their network was penetrated by the Ryuk ransomware virus. Ryuk is generally considered to have been created by North Korean state sponsored criminal gangs, possibly using technology leaked from the U.S. NSA organization. Ryuk targets specific businesses with limited tolerance for disruption and is one of the most profitable versions of ransomware. Major victims include Data Resolution, a California-based data warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a single-location manufacturing company headquartered in the Chicago metro area with around 500 staff members. The Ryuk event had shut down all company operations and manufacturing processes. Most of the client's backups had been online at the beginning of the attack and were destroyed. The client was actively seeking loans for paying the ransom demand (exceeding $200K) and hoping for good luck, but ultimately utilized Progent.


"I can't say enough in regards to the help Progent provided us throughout the most critical time of (our) businesses existence. We may have had to pay the criminal gangs except for the confidence the Progent group afforded us. That you were able to get our e-mail system and important applications back into operation quicker than one week was earth shattering. Every single expert I spoke to or communicated with at Progent was hell bent on getting my company operational and was working day and night to bail us out."

Progent worked hand in hand the client to rapidly get our arms around and assign priority to the essential areas that had to be restored to make it possible to resume business operations:

  • Active Directory (AD)
  • Electronic Mail
  • MRP System
To begin, Progent followed Anti-virus event response industry best practices by isolating and removing active viruses. Progent then initiated the task of restoring Active Directory, the heart of enterprise networks built on Microsoft Windows technology. Microsoft Exchange Server messaging will not operate without AD, and the customer's financials and MRP applications leveraged Microsoft SQL, which depends on Windows AD for access to the data.

Within two days, Progent was able to restore Windows Active Directory to its pre-intrusion state. Progent then charged ahead with setup and storage recovery on critical systems. All Microsoft Exchange Server ties and configuration information were intact, which facilitated the restore of Exchange. Progent was able to locate non-encrypted OST data files (Microsoft Outlook Off-Line Data Files) on user workstations and laptops in order to recover email information. A not too old off-line backup of the client's financials/ERP systems made it possible to recover these vital programs back on-line. Although a lot of work remained to recover completely from the Ryuk event, critical systems were restored rapidly:


"For the most part, the production manufacturing operation was never shut down and we delivered all customer orders."

Over the next month important milestones in the restoration process were made in close cooperation between Progent engineers and the client:

  • Internal web sites were restored with no loss of data.
  • The MailStore Server containing more than four million historical emails was spun up and accessible to users.
  • CRM/Orders/Invoices/AP/Accounts Receivables (AR)/Inventory modules were fully operational.
  • A new Palo Alto 850 firewall was set up and programmed.
  • Ninety percent of the desktop computers were functioning as before the incident.

"A lot of what went on those first few days is mostly a blur for me, but I will not forget the dedication all of the team put in to give us our business back. I have been working with Progent for the past 10 years, maybe more, and every time I needed help Progent has outperformed my expectations and delivered. This situation was a testament to your capabilities."

Conclusion
A possible business disaster was averted due to hard-working professionals, a broad spectrum of subject matter expertise, and tight collaboration. Although upon completion of forensics the ransomware virus penetration detailed here would have been identified and disabled with up-to-date cyber security solutions and NIST Cybersecurity Framework best practices, user education, and appropriate security procedures for data backup and keeping systems up to date with security patches, the fact remains that government-sponsored hackers from China, North Korea and elsewhere are relentless and will continue. If you do get hit by a ransomware attack, feel confident that Progent's team of professionals has proven experience in crypto-ransomware virus blocking, removal, and file disaster recovery.


"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (and any others that were helping), thanks very much for making it so I could get rested after we made it through the first week. All of you did an incredible job, and if anyone is visiting the Chicago area, a great meal is the least I can do!"
