Ransomware : Your Worst IT Nightmare
Ransomware has become a modern cyberplague that represents an existential danger for organizations unprepared for an assault. Different versions of ransomware like the CryptoLocker, WannaCry, Locky, SamSam and MongoLock cryptoworms have been out in the wild for many years and continue to cause damage. Newer versions of ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Snatch or Nephilim, as well as frequent unnamed newcomers, not only do encryption of on-line information but also infiltrate most available system restores and backups. Information replicated to cloud environments can also be rendered useless. In a vulnerable system, this can make automated recovery hopeless and effectively sets the network back to zero.
Getting back on-line services and information following a crypto-ransomware event becomes a race against the clock as the targeted organization struggles to contain and clear the crypto-ransomware and to restore business-critical activity. Since ransomware requires time to replicate, attacks are often sprung during weekends and nights, when penetrations are likely to take longer to recognize. This multiplies the difficulty of rapidly assembling and coordinating a qualified response team.
Progent provides a range of services for securing businesses from ransomware penetrations. These include user training to become familiar with and not fall victim to phishing scams, ProSight Active Security Monitoring for remote monitoring and management, along with setup and configuration of next-generation security gateways with machine learning capabilities to automatically detect and extinguish zero-day cyber attacks. Progent in addition can provide the assistance of seasoned ransomware recovery engineers with the skills and commitment to re-deploy a breached environment as rapidly as possible.
Progent's Ransomware Recovery Support Services
After a crypto-ransomware event, even paying the ransom demands in cryptocurrency does not guarantee that cyber criminals will respond with the codes to decrypt all your data. Kaspersky estimated that 17% of ransomware victims never recovered their files even after having sent off the ransom, resulting in additional losses. The risk is also costly. Ryuk ransoms often range from fifteen to forty BTC ($120,000 and $400,000). This is significantly above the average ransomware demands, which ZDNET determined to be approximately $13,000. The fallback is to re-install the critical parts of your IT environment. Without access to full data backups, this requires a broad range of skill sets, professional project management, and the willingness to work 24x7 until the task is over.

Progent's ransomware team uses top notch project management tools to coordinate the complex recovery process. Progent knows the importance of acting quickly and in unison with a client's management and IT staff to assign priority to tasks and to get the most important systems back on line as soon as humanly possible.
Case Study: A Successful Ransomware Virus Recovery
A client sought out Progent after their network was taken over by the Ryuk ransomware. Ryuk is generally considered to have been developed by Northern Korean state cybercriminals, possibly adopting approaches leaked from Americaís NSA organization. Ryuk attacks specific companies with limited room for operational disruption and is among the most profitable instances of ransomware viruses. High publicized organizations include Data Resolution, a California-based info warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a regional manufacturer headquartered in the Chicago metro area with around 500 staff members. The Ryuk attack had paralyzed all company operations and manufacturing processes. Most of the client's backups had been directly accessible at the beginning of the attack and were encrypted. The client was actively seeking loans for paying the ransom (more than two hundred thousand dollars) and praying for good luck, but in the end utilized Progent.
"I cannot tell you enough about the expertise Progent provided us during the most stressful time of (our) companyís life. We may have had to pay the cyber criminals behind the attack if it wasnít for the confidence the Progent group gave us. That you were able to get our e-mail system and essential applications back on-line sooner than 1 week was incredible. Every single expert I talked with or messaged at Progent was absolutely committed on getting us operational and was working 24 by 7 on our behalf."
Progent worked together with the client to quickly get our arms around and prioritize the most important services that needed to be recovered to make it possible to restart departmental functions:
To start, Progent followed ransomware event response industry best practices by halting lateral movement and clearing infected systems. Progent then began the work of bringing back online Active Directory, the heart of enterprise networks built upon Microsoft technology. Microsoft Exchange messaging will not work without Windows AD, and the customerís accounting and MRP applications utilized Microsoft SQL, which needs Active Directory for security authorization to the data.
- Microsoft Active Directory
In less than 48 hours, Progent was able to rebuild Active Directory services to its pre-penetration state. Progent then assisted with setup and storage recovery on needed servers. All Microsoft Exchange Server data and configuration information were usable, which greatly helped the restore of Exchange. Progent was also able to locate local OST data files (Microsoft Outlook Off-Line Folder Files) on team PCs in order to recover email data. A not too old off-line backup of the customerís accounting systems made them able to recover these essential programs back online for users. Although a large amount of work was left to recover completely from the Ryuk attack, essential services were recovered quickly:
"For the most part, the manufacturing operation survived unscathed and we delivered all customer sales."
Throughout the next few weeks important milestones in the restoration process were completed in tight collaboration between Progent engineers and the client:
- In-house web sites were brought back up with no loss of information.
- The MailStore Server containing more than 4 million historical messages was brought online and available for users.
- CRM/Orders/Invoices/Accounts Payable/AR/Inventory Control functions were 100% operational.
- A new Palo Alto 850 firewall was set up.
- Ninety percent of the desktops and laptops were operational.
"So much of what occurred in the early hours is mostly a haze for me, but we will not forget the dedication all of the team accomplished to give us our business back. Iíve trusted Progent for at least 10 years, possibly more, and every time Progent has shined and delivered as promised. This event was a stunning achievement."
A probable company-ending catastrophe was evaded with top-tier experts, a wide array of subject matter expertise, and tight teamwork. Although upon completion of forensics the crypto-ransomware attack detailed here would have been disabled with up-to-date cyber security technology and recognized best practices, staff education, and well designed security procedures for information backup and proper patching controls, the fact is that government-sponsored cybercriminals from China, Russia, North Korea and elsewhere are relentless and are an ongoing threat. If you do get hit by a crypto-ransomware incursion, feel confident that Progent's team of experts has proven experience in ransomware virus defense, remediation, and information systems disaster recovery.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen and Chris (and any others that were helping), thanks very much for making it so I could get rested after we made it through the initial fire. All of you did an fabulous effort, and if anyone that helped is in the Chicago area, dinner is on me!"
