Crypto-Ransomware : Your Crippling Information Technology Catastrophe
Ransomware has become a too-frequent cyber pandemic that represents an enterprise-level threat for businesses of all sizes vulnerable to an attack. Versions of ransomware such as CryptoLocker, CryptoWall, Locky, SamSam and MongoLock cryptoworms have been running rampant for years and still inflict havoc. Recent strains of crypto-ransomware such as Ryuk, Maze, Sodinokibi, DopplePaymer, Lockbit or Nephilim, as well as frequent as yet unnamed viruses, not only do encryption of online files but also infiltrate many accessible system backups. Files replicated to the cloud can also be encrypted. In a poorly designed system, it can make any recovery useless and basically sets the network back to zero.
Getting back on-line applications and data following a ransomware attack becomes a race against the clock as the victim tries its best to contain the damage and eradicate the ransomware and to resume mission-critical activity. Since ransomware requires time to spread, attacks are usually launched on weekends, when attacks are likely to take longer to uncover. This multiplies the difficulty of rapidly assembling and orchestrating a capable mitigation team.
Progent provides a range of services for protecting enterprises from ransomware events. These include user education to help identify and avoid phishing attempts, ProSight Active Security Monitoring (ASM) for remote monitoring and management, along with deployment of modern security solutions with machine learning capabilities to intelligently discover and suppress new cyber threats. Progent in addition offers the services of expert ransomware recovery consultants with the talent and commitment to re-deploy a compromised network as rapidly as possible.
Progent's Ransomware Restoration Support Services
After a ransomware event, paying the ransom demands in cryptocurrency does not guarantee that distant criminals will provide the needed codes to decrypt any or all of your data. Kaspersky estimated that 17% of ransomware victims never restored their information even after having paid the ransom, resulting in additional losses. The risk is also costly. Ryuk ransoms often range from 15-40 BTC ($120,000 and $400,000). This is greatly higher than the typical crypto-ransomware demands, which ZDNET averages to be approximately $13,000. The other path is to re-install the essential parts of your Information Technology environment. Without the availability of complete data backups, this requires a wide complement of IT skills, top notch project management, and the capability to work non-stop until the task is over.
For decades, Progent has offered certified expert IT services for companies in Raleigh and throughout the U.S. and has earned Microsoft's Gold Partnership certification in the Datacenter and Cloud Productivity competencies.

This breadth of experience gives Progent the ability to knowledgably ascertain necessary systems and integrate the remaining parts of your network environment following a ransomware penetration and configure them into a functioning network.
Progent's recovery group utilizes top notch project management tools to orchestrate the complicated recovery process. Progent appreciates the urgency of working quickly and together with a customerís management and Information Technology staff to prioritize tasks and to put critical systems back on-line as fast as humanly possible.
Customer Case Study: A Successful Crypto-Ransomware Attack Response
A small business escalated to Progent after their network was attacked by the Ryuk ransomware. Ryuk is thought to have been created by North Korean government sponsored cybercriminals, possibly adopting techniques leaked from Americaís NSA organization. Ryuk attacks specific businesses with limited ability to sustain disruption and is among the most profitable instances of ransomware. Major targets include Data Resolution, a California-based info 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 penetration had shut down all company operations and manufacturing capabilities. The majority of the client's system backups had been online at the beginning of the attack and were eventually encrypted. The client was evaluating paying the ransom (more than $200,000) and praying for good luck, but in the end reached out to Progent.
"I cannot tell you enough about the help Progent gave us throughout the most fearful time of (our) companyís existence. We most likely would have paid the cyber criminals behind the attack except for the confidence the Progent team gave us. That you could get our messaging and key servers back on-line faster than five days was earth shattering. Each staff member I got help from or texted at Progent was absolutely committed on getting us working again and was working breakneck pace to bail us out."
Progent worked hand in hand the client to quickly assess and assign priority to the key services that needed to be addressed in order to continue company functions:
To begin, Progent followed ransomware penetration response best practices by isolating and disinfecting systems. Progent then began the steps of restoring Windows Active Directory, the foundation of enterprise environments built upon Microsoft Windows Server technology. Microsoft Exchange Server email will not function without Windows AD, and the businessesí MRP system used Microsoft SQL Server, which requires Active Directory services for authentication to the database.
- Active Directory (AD)
- Electronic Mail
- MRP System
Within 48 hours, Progent was able to rebuild Active Directory to its pre-intrusion state. Progent then charged ahead with reinstallations and hard drive recovery of mission critical systems. All Microsoft Exchange Server data and configuration information were usable, which greatly helped the rebuild of Exchange. Progent was able to assemble non-encrypted OST files (Outlook Off-Line Folder Files) on various workstations to recover email information. A not too old offline backup of the customerís financials/ERP systems made it possible to recover these required applications back on-line. Although a large amount of work still had to be done to recover totally from the Ryuk event, essential systems were restored rapidly:
"For the most part, the manufacturing operation survived unscathed and we produced all customer sales."
Over the following few weeks critical milestones in the recovery process were achieved through tight cooperation between Progent engineers and the customer:
- Self-hosted web sites were brought back up with no loss of information.
- The MailStore Server containing more than 4 million archived messages was restored to operations and accessible to users.
- CRM/Customer Orders/Invoices/Accounts Payable (AP)/Accounts Receivables (AR)/Inventory Control modules were fully functional.
- A new Palo Alto 850 firewall was deployed.
- Most of the desktop computers were being used by staff.
"So much of what transpired that first week is mostly a haze for me, but my management will not soon forget the urgency all of the team put in to give us our business back. Iíve utilized Progent for the past ten years, possibly more, and every time Progent has come through and delivered. This time was a life saver."
A probable business-ending catastrophe was avoided through the efforts of results-oriented professionals, a wide spectrum of knowledge, and tight collaboration. Although in analyzing the event afterwards the crypto-ransomware virus penetration described here would have been stopped with advanced cyber security solutions and NIST Cybersecurity Framework or ISO/IEC 27001 best practices, staff education, and properly executed incident response procedures for backup and keeping systems up to date with security patches, the reality remains that state-sponsored cyber criminals from Russia, China and elsewhere are relentless and will continue. If you do fall victim to a crypto-ransomware incident, feel confident that Progent's roster of professionals has substantial experience in ransomware virus blocking, remediation, and data restoration.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others who were involved), thank you for letting me get some sleep after we got through the initial fire. All of you did an impressive effort, and if anyone that helped is in the Chicago area, dinner is the least I can do!"
