Crypto-Ransomware : Your Feared Information Technology Nightmare
Ransomware has become a too-frequent cyberplague that poses an enterprise-level threat for businesses unprepared for an assault. Different versions of ransomware like the Reveton, Fusob, Bad Rabbit, NotPetya and MongoLock cryptoworms have been out in the wild for years and continue to inflict damage. The latest versions of ransomware such as Ryuk and Hermes, as well as more unnamed newcomers, not only do encryption of on-line files but also infect all available system backups. Data synched to the cloud can also be corrupted. In a poorly designed system, this can make automated restore operations useless and basically sets the entire system back to square one.
Recovering programs and information following a crypto-ransomware event becomes a race against the clock as the targeted organization tries its best to contain and remove the crypto-ransomware and to resume business-critical activity. Since crypto-ransomware requires time to move laterally, penetrations are often launched on weekends, when penetrations are likely to take more time to uncover. This compounds the difficulty of quickly assembling and coordinating a capable response team.
Progent provides an assortment of solutions for securing businesses from crypto-ransomware events. These include staff education to help recognize and avoid phishing exploits, ProSight Active Security Monitoring (ASM) for remote monitoring and management, along with installation of next-generation security solutions with artificial intelligence capabilities to automatically discover and suppress zero-day cyber threats. Progent also provides the services of experienced ransomware recovery engineers with the talent and perseverance to re-deploy a breached network as quickly as possible.
Progent's Ransomware Recovery Services
Soon after a crypto-ransomware event, even paying the ransom demands in cryptocurrency does not ensure that criminal gangs will respond with the needed codes to unencrypt all your data. Kaspersky Labs ascertained that seventeen percent of crypto-ransomware victims never restored their data 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 greatly above the average crypto-ransomware demands, which ZDNET averages to be in the range of $13,000. The fallback is to piece back together the vital elements of your IT environment. Without the availability of complete information backups, this calls for a broad range of skills, professional project management, and the ability to work 24x7 until the job is complete.

Progent's recovery team uses top notch project management systems to orchestrate the complex recovery process. Progent knows the importance of working quickly and in concert with a client's management and Information Technology team members to prioritize tasks and to put essential services back on line as soon as humanly possible.
Case Study: A Successful Ransomware Penetration Response
A business engaged Progent after their company was attacked by Ryuk ransomware. Ryuk is thought to have been developed by Northern Korean government sponsored criminal gangs, possibly adopting techniques leaked from the United States NSA organization. Ryuk goes after specific businesses with little ability to sustain disruption and is among the most profitable incarnations of ransomware viruses. Major organizations include Data Resolution, a California-based data warehousing and cloud computing company, and the Chicago Tribune. Progent's customer is a small manufacturing business based in the Chicago metro area and has around 500 workers. The Ryuk penetration had shut down all company operations and manufacturing processes. The majority of the client's data protection had been on-line at the start of the attack and were eventually encrypted. The client was actively seeking loans for paying the ransom demand (more than $200K) and wishfully thinking for good luck, but in the end brought in Progent.
"I canít say enough about the expertise Progent provided us during the most stressful time of (our) companyís existence. We had little choice but to pay the criminal gangs except for the confidence the Progent experts afforded us. That you could get our e-mail system and key servers back into operation in less than one week was amazing. Every single expert I worked with or messaged at Progent was totally committed on getting us restored and was working all day and night to bail us out."
Progent worked with the customer to rapidly determine and assign priority to the essential elements that had to be restored in order to restart departmental functions:
To get going, Progent followed Anti-virus event response best practices by isolating and removing active viruses. Progent then started the work of restoring Windows Active Directory, the heart of enterprise systems built upon Microsoft technology. Exchange messaging will not work without Active Directory, and the client's MRP applications used Microsoft SQL, which depends on Active Directory for authentication to the information.
- Active Directory (AD)
- Exchange Server
- MRP System
Within two days, Progent was able to recover Active Directory to its pre-intrusion state. Progent then helped perform rebuilding and storage recovery of key servers. All Exchange ties and attributes were intact, which facilitated the restore of Exchange. Progent was also able to assemble local OST data files (Outlook Offline Folder Files) on staff PCs and laptops to recover email messages. A not too old offline backup of the client's manufacturing software made it possible to return these vital services back servicing users. Although major work needed to be completed to recover completely from the Ryuk damage, the most important systems were returned to operations rapidly:
"For the most part, the production line operation was never shut down and we delivered all customer shipments."
Over the following couple of weeks important milestones in the restoration project were made through close cooperation between Progent consultants and the customer:
- Self-hosted web sites were restored with no loss of information.
- The MailStore Microsoft Exchange Server exceeding 4 million historical emails was restored to operations and accessible to users.
- CRM/Customer Orders/Invoices/AP/Accounts Receivables (AR)/Inventory capabilities were 100 percent recovered.
- A new Palo Alto 850 security appliance was set up.
- 90% of the desktops and laptops were fully operational.
"So much of what occurred in the initial days is mostly a haze for me, but we will not soon forget the dedication each of the team put in to give us our business back. I have been working with Progent for at least 10 years, possibly more, and every time I needed help Progent has outperformed my expectations and delivered as promised. This event was a Herculean accomplishment."
A probable business catastrophe was evaded by top-tier professionals, a broad range of subject matter expertise, and close teamwork. Although in post mortem the crypto-ransomware attack detailed here could have been disabled with current security technology solutions and security best practices, staff education, and well designed incident response procedures for data protection and proper patching controls, the reality is that government-sponsored cybercriminals from Russia, China and elsewhere are tireless and will continue. If you do get hit by a ransomware incident, feel confident that Progent's roster of professionals has extensive experience in ransomware virus blocking, remediation, and data restoration.
"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others that were helping), thank you for letting me get rested after we made it over the first week. Everyone did an amazing job, and if any of your guys is visiting the Chicago area, dinner is the least I can do!"
