Ransomware : Your Feared IT Nightmare
Crypto-Ransomware has become a modern cyber pandemic that poses an existential threat for businesses poorly prepared for an assault. Versions of crypto-ransomware like the CryptoLocker, CryptoWall, Bad Rabbit, NotPetya and MongoLock cryptoworms have been around for years and still inflict havoc. Newer strains of ransomware like Ryuk and Hermes, plus frequent unnamed viruses, not only encrypt online files but also infect many accessible system backups. Information synched to cloud environments can also be rendered useless. In a poorly designed data protection solution, it can render automated restore operations hopeless and basically sets the network back to zero.
Restoring applications and data following a ransomware intrusion becomes a sprint against the clock as the victim struggles to contain and cleanup the crypto-ransomware and to restore business-critical operations. Due to the fact that crypto-ransomware needs time to move laterally, penetrations are usually launched during nights and weekends, when attacks in many cases take longer to detect. This compounds the difficulty of quickly assembling and organizing an experienced mitigation team.
Progent makes available a variety of support services for protecting enterprises from crypto-ransomware penetrations. These include user training to become familiar with and avoid phishing scams, ProSight Active Security Monitoring for remote monitoring and management, plus setup and configuration of next-generation security appliances with machine learning technology to rapidly discover and suppress new cyber threats. Progent also offers the assistance of seasoned crypto-ransomware recovery engineers with the track record and perseverance to restore a breached environment as quickly as possible.
Progent's Ransomware Restoration Support Services
After a ransomware penetration, sending the ransom in cryptocurrency does not guarantee that distant criminals will provide the needed keys to decipher all your information. Kaspersky estimated that 17% of crypto-ransomware victims never recovered their data after having sent off the ransom, resulting in more losses. The gamble is also costly. Ryuk ransoms often range from fifteen to forty BTC ($120,000 and $400,000). This is significantly higher than the average ransomware demands, which ZDNET determined to be approximately $13,000. The other path is to setup from scratch the mission-critical parts of your IT environment. Without access to complete system backups, this calls for a wide range of skills, professional project management, and the capability to work 24x7 until the task is over.

Progent knows the urgency of acting quickly and together with a customerís management and IT team members to prioritize tasks and to put essential services back on-line as soon as possible.
Business Case Study: A Successful Crypto-Ransomware Virus Response
A customer escalated to Progent after their network was taken over by Ryuk ransomware. Ryuk is generally considered to have been deployed by North Korean state sponsored cybercriminals, possibly adopting algorithms exposed from Americaís NSA organization. Ryuk targets specific companies with limited ability to sustain disruption and is one of the most profitable examples of crypto-ransomware. Well Known targets include Data Resolution, a California-based information warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a small manufacturing business located in the Chicago metro area and has about 500 employees. The Ryuk intrusion had frozen all business operations and manufacturing capabilities. The majority of the client's data backups had been on-line at the time of the intrusion and were encrypted. The client was actively seeking loans for paying the ransom (exceeding two hundred thousand dollars) and hoping for good luck, but ultimately reached out to Progent.
"I cannot speak enough in regards to the expertise Progent provided us during the most critical time of (our) businesses survival. We would have paid the cybercriminals if it wasnít for the confidence the Progent team gave us. The fact that you could get our e-mail and key applications back into operation in less than a week was earth shattering. Every single expert I worked with or texted at Progent was amazingly focused on getting us operational and was working non-stop on our behalf."
Progent worked together with the client to quickly assess and assign priority to the most important services that needed to be restored to make it possible to resume departmental operations:
To begin, Progent adhered to Anti-virus event response industry best practices by halting lateral movement and disinfecting systems. Progent then started the task of recovering Microsoft Active Directory, the core of enterprise environments built on Microsoft technology. Microsoft Exchange email will not function without Active Directory, and the customerís financials and MRP software used Microsoft SQL, which requires Windows AD for authentication to the database.
- Active Directory (AD)
- Accounting and Manufacturing Software
Within two days, Progent was able to restore Active Directory to its pre-intrusion state. Progent then assisted with reinstallations and storage recovery of key applications. All Exchange Server schema and configuration information were usable, which greatly helped the rebuild of Exchange. Progent was also able to collect intact OST files (Outlook Email Offline Data Files) on staff desktop computers in order to recover mail messages. A recent offline backup of the customerís financials/ERP systems made them able to restore these essential programs back servicing users. Although a large amount of work was left to recover fully from the Ryuk virus, the most important services were returned to operations rapidly:
"For the most part, the assembly line operation was never shut down and we produced all customer deliverables."
Throughout the following couple of weeks critical milestones in the recovery project were achieved through close collaboration between Progent engineers and the client:
- Internal web sites were returned to operation with no loss of data.
- The MailStore Microsoft Exchange Server with over four million historical emails was spun up and available for users.
- CRM/Product Ordering/Invoicing/AP/Accounts Receivables (AR)/Inventory Control capabilities were completely operational.
- A new Palo Alto 850 firewall was installed and configured.
- Ninety percent of the desktop computers were operational.
"A lot of what occurred those first few days is nearly entirely a blur for me, but my management will not forget the urgency each and every one of the team accomplished to give us 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 time was a testament to your capabilities."
A probable business disaster was avoided due to top-tier professionals, a wide spectrum of knowledge, and tight collaboration. Although upon completion of forensics the ransomware virus penetration detailed here could have been blocked with current cyber security technology and NIST Cybersecurity Framework best practices, user training, and properly executed security procedures for information backup and keeping systems up to date with security patches, the reality remains that state-sponsored hackers from Russia, China and elsewhere are relentless and are an ongoing threat. If you do fall victim to a ransomware incursion, remember that Progent's roster of professionals has a proven track record in ransomware virus defense, remediation, and data recovery.
"So, to Darrin, Matt, Aaron, Claude, Jesse, Arnaud, Allen, Tony and Chris (and any others that were contributing), thank you for letting me get some sleep after we got through the initial fire. All of you did an fabulous job, and if any of your guys is around the Chicago area, dinner is the least I can do!"
