Crypto-Ransomware : Your Worst Information Technology Catastrophe
Ransomware has become a modern cyberplague that presents an enterprise-level danger for organizations vulnerable to an assault. Versions of ransomware such as CrySIS, CryptoWall, Locky, SamSam and MongoLock cryptoworms have been out in the wild for a long time and continue to inflict havoc. The latest strains of crypto-ransomware like Ryuk and Hermes, plus more as yet unnamed malware, not only encrypt online information but also infiltrate all accessible system backup. Files synchronized to the cloud can also be rendered useless. In a poorly designed environment, this can make any recovery impossible and effectively knocks the network back to zero.
Getting back services and data following a ransomware event becomes a sprint against the clock as the targeted business struggles to contain the damage and eradicate the virus and to resume enterprise-critical activity. Because ransomware requires time to move laterally, penetrations are usually launched on weekends and holidays, when successful attacks tend to take longer to discover. This multiplies the difficulty of quickly assembling and coordinating a qualified mitigation team.
Progent makes available a variety of support services for securing enterprises from ransomware attacks. These include team training to become familiar with and avoid phishing exploits, ProSight Active Security Monitoring for remote monitoring and management, along with deployment of next-generation security gateways with AI technology to rapidly detect and disable zero-day cyber threats. Progent in addition offers the services of expert ransomware recovery engineers with the talent and commitment to restore a compromised environment as rapidly as possible.
Progent's Crypto-Ransomware Restoration Services
Soon after a crypto-ransomware attack, even paying the ransom demands in Bitcoin cryptocurrency does not ensure that criminal gangs will provide the codes to decrypt any or all of your information. Kaspersky determined that seventeen percent of crypto-ransomware victims never recovered their data after having sent off the ransom, resulting in additional losses. The risk is also expensive. Ryuk ransoms often range from 15-40 BTC ($120,000 and $400,000). This is significantly above the usual ransomware demands, which ZDNET determined to be in the range of $13,000. The fallback is to piece back together the critical components of your IT environment. Without the availability of complete data backups, this requires a broad range of skills, well-coordinated project management, and the ability to work continuously until the task is completed.

Progent's recovery group has powerful project management applications to coordinate the complex restoration process. Progent appreciates the importance of working swiftly and in unison with a client's management and IT resources to prioritize tasks and to put essential systems back on-line as fast as humanly possible.
Client Story: A Successful Ransomware Intrusion Restoration
A client hired Progent after their organization was brought down by Ryuk ransomware. Ryuk is thought to have been deployed by North Korean government sponsored hackers, possibly using approaches exposed from Americaís NSA organization. Ryuk seeks specific organizations with limited ability to sustain disruption and is among the most lucrative examples of ransomware. Major organizations include Data Resolution, a California-based data warehousing and cloud computing firm, and the Chicago Tribune. Progent's client is a small manufacturer based in Chicago with around 500 staff members. The Ryuk attack had disabled all essential operations and manufacturing capabilities. Most of the client's data backups had been on-line at the start of the attack and were encrypted. The client was pursuing financing for paying the ransom demand (more than $200,000) and hoping for good luck, but ultimately brought in Progent.
"I cannot speak enough in regards to the care Progent gave us during 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 group provided us. That you could get our e-mail system and important applications back on-line in less than seven days was incredible. Each expert I talked with or communicated with at Progent was absolutely committed on getting us operational and was working day and night on our behalf."
Progent worked with the customer to quickly assess and assign priority to the mission critical areas that needed to be recovered in order to resume company functions:
To get going, Progent followed Anti-virus penetration response industry best practices by halting the spread and cleaning systems of viruses. Progent then started the steps of recovering Active Directory, the heart of enterprise environments built on Microsoft technology. Microsoft Exchange email will not function without AD, and the client's MRP system used Microsoft SQL, which depends on Windows AD for security authorization to the information.
- Active Directory
- Microsoft Exchange Server
Within 2 days, Progent was able to recover Windows Active Directory to its pre-intrusion state. Progent then initiated rebuilding and storage recovery of the most important systems. All Microsoft Exchange Server data and attributes were intact, which facilitated the rebuild of Exchange. Progent was also able to assemble non-encrypted OST data files (Outlook Email Off-Line Data Files) on various workstations in order to recover mail information. A not too old offline backup of the client's financials/ERP systems made them able to restore these essential services back available to users. Although a lot of work remained to recover fully from the Ryuk event, core systems were recovered quickly:
"For the most part, the manufacturing operation did not miss a beat and we made all customer shipments."
During the following few weeks critical milestones in the restoration process were made in tight collaboration between Progent consultants and the customer:
- In-house web applications were restored with no loss of data.
- The MailStore Server with over four million historical emails was spun up and available for users.
- CRM/Orders/Invoicing/AP/Accounts Receivables/Inventory Control capabilities were completely restored.
- A new Palo Alto 850 firewall was deployed.
- 90% of the user desktops were functioning as before the incident.
"A huge amount of what was accomplished during the initial response is nearly entirely a fog for me, but my management will not forget the care each and every one of your team accomplished to help get our company back. Iíve utilized Progent for the past ten years, possibly more, and each time Progent has impressed me and delivered as promised. This event was a testament to your capabilities."
A possible company-ending disaster was dodged with hard-working experts, a wide range of subject matter expertise, and close collaboration. Although in hindsight the crypto-ransomware incident described here should have been identified and blocked with modern security technology and security best practices, team education, and well thought out security procedures for data protection and proper patching controls, the fact is that state-sponsored hackers from China, North Korea and elsewhere are tireless and represent an ongoing threat. If you do fall victim to a ransomware incident, remember that Progent's roster of experts has a proven track record in ransomware virus blocking, remediation, and information systems recovery.
"So, to Darrin, Aaron, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others that were involved), thanks very much for letting me get some sleep after we made it through the first week. Everyone did an incredible job, and if anyone that helped is in the Chicago area, a great meal is on me!"
