Crypto-Ransomware : Your Crippling IT Disaster
Ransomware  Remediation ConsultantsCrypto-Ransomware has become an escalating cyberplague that poses an enterprise-level danger for organizations vulnerable to an attack. Versions of ransomware like the CryptoLocker, WannaCry, Locky, NotPetya and MongoLock cryptoworms have been replicating for a long time and continue to cause destruction. Newer strains of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Conti and Egregor, plus more unnamed newcomers, not only perform encryption of on-line files but also infect any accessible system protection. Data synchronized to cloud environments can also be rendered useless. In a poorly designed data protection solution, this can render automated recovery hopeless and effectively knocks the datacenter back to square one.

Getting back programs and data after a ransomware event becomes a sprint against time as the targeted organization tries its best to contain the damage, clear the ransomware, and resume mission-critical activity. Because crypto-ransomware requires time to replicate throughout a targeted network, assaults are often launched during weekends and nights, when successful attacks may take more time to recognize. This compounds the difficulty of promptly mobilizing and organizing a knowledgeable mitigation team.

Progent provides an assortment of help services for securing Dayton enterprises from crypto-ransomware attacks. These include team education to become familiar with and not fall victim to phishing attempts, ProSight Active Security Monitoring (ASM) for endpoint detection and response utilizing SentinelOne's behavior-based threat defense to detect and suppress day-zero modern malware assaults. Progent also provides the assistance of experienced ransomware recovery consultants with the skills and perseverance to re-deploy a breached system as quickly as possible.

Progent's Crypto-Ransomware Restoration Services
Subsequent to a ransomware attack, even paying the ransom in cryptocurrency does not provide any assurance that criminal gangs will respond with the needed keys to decrypt any or all of your files. Kaspersky estimated that seventeen percent of crypto-ransomware victims never recovered their files after having paid the ransom, resulting in more losses. The risk is also expensive. Ryuk ransoms are commonly a few hundred thousand dollars. For larger organizations, the ransom can reach millions of dollars. The other path is to setup from scratch the essential parts of your IT environment. Absent the availability of full data backups, this calls for a wide complement of skill sets, well-coordinated team management, and the ability to work continuously until the recovery project is done.

Progent's ransomware team deploys best of breed project management tools to coordinate the complex recovery process. Progent appreciates the importance of working quickly and in unison with a client's management and IT staff to assign priority to tasks and to put key applications back online as soon as possible.

Customer Story: A Successful Ransomware Penetration Response
A client hired Progent after their network system was brought down by Ryuk crypto-ransomware. Ryuk is believed to have been launched by North Korean government sponsored cybercriminals, possibly using techniques exposed from the United States National Security Agency. Ryuk targets specific organizations with limited ability to sustain disruption and is one of the most lucrative iterations of ransomware viruses. Well Known victims include Data Resolution, a California-based info warehousing and cloud computing company, and the Chicago Tribune. Progent's client is a single-location manufacturer located in Chicago with about 500 staff members. The Ryuk intrusion had paralyzed all company operations and manufacturing capabilities. The majority of the client's system backups had been directly accessible at the beginning of the attack and were damaged. The client was pursuing financing for paying the ransom (exceeding two hundred thousand dollars) and praying for the best, but ultimately brought in Progent.


"I can't thank you enough in regards to the care Progent gave us during the most critical period of (our) businesses existence. We had little choice but to pay the cyber criminals behind the attack except for the confidence the Progent group provided us. The fact that you could get our e-mail system and critical servers back online faster than 1 week was amazing. Every single expert I worked with or texted at Progent was hell bent on getting us operational and was working at all hours to bail us out."

Progent worked with the client to quickly understand and prioritize the essential applications that needed to be recovered in order to resume business operations:

  • Active Directory
  • Electronic Messaging
  • Accounting and Manufacturing Software
To begin, Progent adhered to AV/Malware Processes event mitigation best practices by halting lateral movement and clearing infected systems. Progent then initiated the work of rebuilding Microsoft AD, the foundation of enterprise environments built upon Microsoft Windows technology. Microsoft Exchange email will not work without AD, and the client's financials and MRP system used Microsoft SQL Server, which depends on Active Directory for access to the information.

Within 48 hours, Progent was able to rebuild Windows Active Directory to its pre-attack state. Progent then accomplished setup and hard drive recovery of critical applications. All Exchange Server ties and attributes were usable, which greatly helped the restore of Exchange. Progent was able to collect non-encrypted OST data files (Outlook Email Off-Line Folder Files) on team PCs to recover mail data. A recent off-line backup of the client's accounting/ERP systems made it possible to recover these vital services back available to users. Although a large amount of work was left to recover totally from the Ryuk damage, critical services were restored quickly:


"For the most part, the manufacturing operation did not miss a beat and we did not miss any customer shipments."

During the following couple of weeks key milestones in the recovery process were accomplished in close collaboration between Progent consultants and the client:

  • Internal web applications were returned to operation without losing any data.
  • The MailStore Microsoft Exchange Server exceeding 4 million historical messages was brought online and accessible to users.
  • CRM/Orders/Invoicing/AP/Accounts Receivables (AR)/Inventory Control functions were fully recovered.
  • A new Palo Alto Networks 850 security appliance was set up and programmed.
  • Most of the desktops and laptops were being used by staff.

"So much of what transpired in the initial days is nearly entirely a blur for me, but my management will not soon forget the dedication each of the team put in to give us our company back. I've entrusted Progent for at least 10 years, maybe more, and every time Progent has come through and delivered as promised. This time was the most impressive ever."

Conclusion
A potential business extinction catastrophe was avoided due to hard-working professionals, a wide array of technical expertise, and close teamwork. Although in retrospect the crypto-ransomware virus attack detailed here could have been identified and stopped with advanced cyber security technology solutions and NIST Cybersecurity Framework or ISO/IEC 27001 best practices, team education, and appropriate security procedures for information protection and applying software patches, the fact is that government-sponsored hackers from Russia, China and elsewhere are relentless and are an ongoing threat. If you do get hit by a crypto-ransomware attack, remember that Progent's team of experts has extensive experience in ransomware virus defense, mitigation, and data restoration.


"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others who were contributing), thank you for letting me get rested after we got over the initial push. Everyone did an fabulous effort, and if anyone is visiting the Chicago area, a great meal is on me!"
