Crypto-Ransomware : Your Worst IT Nightmare
Crypto-Ransomware has become a too-frequent cyber pandemic that poses an existential threat for organizations poorly prepared for an assault. Multiple generations of ransomware such as CrySIS, WannaCry, Bad Rabbit, Syskey and MongoLock cryptoworms have been replicating for many years and continue to cause harm. Modern variants of ransomware such as Ryuk and Hermes, along with daily unnamed viruses, not only encrypt on-line data but also infect any configured system protection mechanisms. Information synched to off-site disaster recovery sites can also be corrupted. In a poorly architected environment, it can make automated recovery impossible and basically sets the network back to zero.
Getting back online applications and data after a ransomware attack becomes a race against the clock as the targeted business fights to stop the spread and cleanup the ransomware and to restore enterprise-critical activity. Since crypto-ransomware takes time to replicate, penetrations are usually launched on weekends and holidays, when penetrations may take more time to notice. This multiplies the difficulty of rapidly marshalling and orchestrating a knowledgeable response team.
Progent provides a variety of help services for protecting businesses from crypto-ransomware attacks. Among these are staff education to help identify and avoid phishing exploits, ProSight Active Security Monitoring (ASM) for remote monitoring and management, in addition to setup and configuration of modern security appliances with AI technology to quickly discover and quarantine zero-day threats. Progent also provides the assistance of seasoned ransomware recovery consultants with the talent and perseverance to reconstruct a compromised environment as rapidly as possible.
Progent's Ransomware Restoration Help
Subsequent to a ransomware penetration, even paying the ransom demands in cryptocurrency does not ensure that distant criminals will return the keys to decrypt all your information. Kaspersky estimated that 17% of ransomware victims never recovered their information even after having sent off the ransom, resulting in additional losses. The risk is also very costly. Ryuk ransoms commonly range from 15-40 BTC ($120,000 and $400,000). This is significantly higher than the typical crypto-ransomware demands, which ZDNET determined to be around $13,000. The fallback is to piece back together the key parts of your IT environment. Without access to essential system backups, this requires a wide complement of IT skills, well-coordinated project management, and the willingness to work continuously until the task is completed.

Customer Case Study: A Successful Crypto-Ransomware Intrusion Response
A business escalated to Progent after their organization was taken over by Ryuk crypto-ransomware. Ryuk is thought to have been deployed by North Korean government sponsored criminal gangs, suspected of adopting techniques leaked from Americaís National Security Agency. Ryuk goes after specific businesses with little room for operational disruption and is among the most lucrative examples of ransomware viruses. Headline victims include Data Resolution, a California-based data warehousing and cloud computing firm, and the Chicago Tribune. Progent's client is a single-location manufacturing business located in the Chicago metro area with around 500 employees. The Ryuk attack had paralyzed all company operations and manufacturing processes. Most of the client's data protection had been directly accessible at the time of the attack and were eventually encrypted. The client considered paying the ransom demand (more than two hundred thousand dollars) and praying for good luck, but in the end made the decision to use Progent.
"I cannot speak enough in regards to the help Progent gave us throughout the most fearful time of (our) businesses existence. We may have had to pay the cyber criminals behind the attack if not for the confidence the Progent team afforded us. That you could get our e-mail and key applications back into operation quicker than five days was incredible. Each person I got help from or e-mailed at Progent was amazingly focused on getting our system up and was working 24 by 7 on our behalf."
Progent worked hand in hand the client to rapidly identify and prioritize the essential elements that had to be restored in order to resume departmental functions:
To begin, Progent adhered to AV/Malware Processes event response industry best practices by stopping the spread and cleaning systems of viruses. Progent then initiated the steps of recovering Windows Active Directory, the foundation of enterprise networks built upon Microsoft Windows technology. Microsoft Exchange Server messaging will not function without Active Directory, and the customerís MRP system leveraged Microsoft SQL Server, which depends on Windows AD for security authorization to the data.
- Active Directory (AD)
- Microsoft Exchange Server
- MRP System
In less than 48 hours, Progent was able to re-build Windows Active Directory to its pre-intrusion state. Progent then assisted with reinstallations and storage recovery on the most important applications. All Microsoft Exchange Server schema and attributes were usable, which greatly helped the restore of Exchange. Progent was able to assemble non-encrypted OST files (Microsoft Outlook Offline Data Files) on team PCs in order to recover email information. A recent offline backup of the businesses accounting/MRP software made them able to recover these required services back available to users. Although a large amount of work was left to recover completely from the Ryuk attack, the most important systems were restored rapidly:
"For the most part, the production operation did not miss a beat and we did not miss any customer sales."
During the following few weeks key milestones in the recovery process were accomplished through tight cooperation between Progent team members and the customer:
- In-house web applications were restored without losing any data.
- The MailStore Server containing more than four million archived messages was restored to operations and available for users.
- CRM/Product Ordering/Invoicing/AP/Accounts Receivables/Inventory Control functions were completely recovered.
- A new Palo Alto Networks 850 firewall was brought online.
- Nearly all of the user desktops and notebooks were operational.
"So much of what went on during the initial response is nearly entirely a blur for me, but my team will not forget the countless hours each of your team accomplished to help get our business back. I have been working together with Progent for at least 10 years, maybe more, and each time I needed help Progent has outperformed my expectations and delivered as promised. This situation was the most impressive ever."
A possible company-ending catastrophe was avoided through the efforts of dedicated professionals, a broad range of technical expertise, and close collaboration. Although in hindsight the crypto-ransomware incident described here should have been shut down with advanced security technology and best practices, team education, and well designed incident response procedures for information backup and keeping systems up to date with security patches, the fact remains that state-sponsored cybercriminals from Russia, China and elsewhere are relentless and are not going away. If you do fall victim to a ransomware incursion, remember that Progent's team of experts has proven experience in crypto-ransomware virus defense, removal, and data disaster recovery.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Tony and Chris (along with others who were helping), Iím grateful for allowing me to get some sleep after we made it through the initial fire. Everyone did an fabulous effort, and if anyone that helped is around the Chicago area, a great meal is the least I can do!"
