Crypto-Ransomware : Your Worst IT Catastrophe
Ransomware has become a too-frequent cyber pandemic that represents an existential danger for businesses unprepared for an attack. Different versions of ransomware like the Reveton, WannaCry, Locky, SamSam and MongoLock cryptoworms have been circulating for years and continue to inflict destruction. Modern variants of ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Lockbit or Nephilim, plus additional as yet unnamed newcomers, not only do encryption of on-line critical data but also infiltrate all configured system backups. Files replicated to off-site disaster recovery sites can also be rendered useless. In a vulnerable environment, it can render automated restore operations hopeless and effectively sets the entire system back to zero.
Retrieving programs and data following a crypto-ransomware attack becomes a sprint against time as the victim tries its best to stop the spread and remove the ransomware and to restore mission-critical activity. Due to the fact that ransomware requires time to move laterally, assaults are frequently launched during nights and weekends, when penetrations are likely to take longer to identify. This multiplies the difficulty of promptly mobilizing and orchestrating a capable mitigation team.
Progent offers a range of solutions for protecting enterprises from crypto-ransomware events. Among these are team education to help identify and not fall victim to phishing attempts, ProSight Active Security Monitoring for remote monitoring and management, in addition to installation of next-generation security solutions with artificial intelligence technology to intelligently identify and extinguish zero-day cyber attacks. Progent in addition offers the assistance of experienced ransomware recovery professionals with the skills and perseverance to rebuild a compromised environment as quickly as possible.
Progent's Ransomware Recovery Help
Soon after a ransomware penetration, even paying the ransom in cryptocurrency does not provide any assurance that criminal gangs will respond with the keys to unencrypt any or all of your information. Kaspersky Labs determined that seventeen percent of ransomware victims never restored their data after having sent off the ransom, resulting in increased losses. The gamble is also very costly. Ryuk ransoms often range from 15-40 BTC ($120,000 and $400,000). This is greatly above the typical ransomware demands, which ZDNET estimates to be around $13,000. The alternative is to setup from scratch the vital parts of your IT environment. Absent the availability of essential system backups, this requires a wide range of skill sets, top notch team management, and the capability to work continuously until the recovery project is finished.

Progent knows the importance of acting rapidly and together with a client's management and Information Technology resources to prioritize tasks and to get the most important systems back online as soon as possible.
Case Study: A Successful Crypto-Ransomware Intrusion Recovery
A client contacted Progent after their organization was attacked by Ryuk ransomware. Ryuk is generally considered to have been deployed by North Korean government sponsored criminal gangs, suspected of adopting algorithms exposed from the U.S. National Security Agency. Ryuk targets specific businesses with limited tolerance for disruption and is one of the most profitable examples of ransomware. Headline victims include Data Resolution, a California-based data warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a regional manufacturing business headquartered in the Chicago metro area with around 500 employees. The Ryuk attack had brought down all essential operations and manufacturing processes. Most of the client's system backups had been directly accessible at the start of the intrusion and were eventually encrypted. The client was evaluating paying the ransom (in excess of two hundred thousand dollars) and wishfully thinking for the best, but ultimately reached out to Progent.
"I canít tell you enough about the support Progent provided us during the most critical time of (our) companyís life. We most likely would have paid the Hackers if it wasnít for the confidence the Progent group gave us. That you could get our e-mail and essential servers back on-line faster than five days was amazing. Every single expert I talked with or e-mailed at Progent was absolutely committed on getting us restored and was working at all hours on our behalf."
Progent worked together with the customer to rapidly assess and prioritize the essential applications that had to be recovered to make it possible to resume departmental operations:
To get going, Progent followed AV/Malware Processes incident mitigation industry best practices by isolating and cleaning systems of viruses. Progent then initiated the work of rebuilding Active Directory, the heart of enterprise environments built on Microsoft Windows Server technology. Exchange email will not operate without Active Directory, and the customerís financials and MRP applications leveraged Microsoft SQL, which needs Active Directory services for authentication to the database.
- Microsoft Active Directory
In less than 2 days, Progent was able to rebuild Active Directory services to its pre-penetration state. Progent then helped perform setup and hard drive recovery on critical applications. All Microsoft Exchange Server data and attributes were intact, which facilitated the rebuild of Exchange. Progent was able to collect non-encrypted OST data files (Outlook Email Off-Line Folder Files) on team desktop computers to recover email information. A not too old off-line backup of the customerís accounting/MRP software made them able to restore these essential programs back available to users. Although a lot of work remained to recover fully from the Ryuk event, core services were returned to operations quickly:
"For the most part, the production manufacturing operation showed little impact and we produced all customer shipments."
During the next couple of weeks critical milestones in the restoration process were completed in tight cooperation between Progent engineers and the customer:
- Self-hosted web sites were restored with no loss of data.
- The MailStore Microsoft Exchange Server exceeding four million archived messages was brought on-line and accessible to users.
- CRM/Product Ordering/Invoicing/AP/AR/Inventory functions were completely restored.
- A new Palo Alto Networks 850 security appliance was set up and programmed.
- Most of the user workstations were fully operational.
"So much of what happened those first few days is mostly a haze for me, but my management will not forget the care all of you accomplished to help get our company back. Iíve entrusted Progent for the past 10 years, possibly more, and every time I needed help Progent has come through and delivered as promised. This time was the most impressive ever."
A possible enterprise-killing catastrophe was evaded by results-oriented experts, a wide array of technical expertise, and tight collaboration. Although in post mortem the ransomware attack described here could have been identified and disabled with advanced security technology and best practices, team education, and properly executed incident response procedures for information backup and applying software patches, the reality remains that government-sponsored cybercriminals from China, Russia, North Korea and elsewhere are tireless and represent an ongoing threat. If you do get hit by a crypto-ransomware incident, feel confident that Progent's roster of professionals has proven experience in ransomware virus blocking, mitigation, and data restoration.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen and Chris (and any others who were involved), thank you for allowing me to get rested after we made it over the initial fire. Everyone did an fabulous effort, and if anyone is in the Chicago area, dinner is on me!"
