Ransomware : Your Worst IT Nightmare
Ransomware has become a too-frequent cyber pandemic that presents an existential threat for businesses poorly prepared for an attack. Different iterations of crypto-ransomware such as CrySIS, CryptoWall, Locky, NotPetya and MongoLock cryptoworms have been running rampant for many years and continue to cause destruction. Modern variants of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Lockbit or Nephilim, as well as additional as yet unnamed newcomers, not only encrypt on-line files but also infect all available system restores and backups. Files synchronized to the cloud can also be rendered useless. In a vulnerable data protection solution, it can make any recovery hopeless and effectively sets the network back to zero.
Getting back online services and data following a ransomware attack becomes a race against time as the victim struggles to stop lateral movement and eradicate the virus and to resume mission-critical activity. Because crypto-ransomware needs time to move laterally, assaults are often sprung at night, when successful penetrations are likely to take longer to identify. This compounds the difficulty of quickly assembling and orchestrating an experienced mitigation team.
Progent has an assortment of services for protecting organizations from ransomware attacks. These include staff training to help identify and avoid phishing scams, ProSight Active Security Monitoring for remote monitoring and management, in addition to deployment of the latest generation security gateways with artificial intelligence capabilities to intelligently discover and disable new cyber threats. Progent in addition provides the services of experienced ransomware recovery engineers with the track record and perseverance to reconstruct a breached environment as quickly as possible.
Progent's Ransomware Recovery Support Services
Soon after a ransomware event, sending the ransom in cryptocurrency does not guarantee that merciless criminals will provide the keys to decipher any of your information. Kaspersky Labs determined that 17% of ransomware victims never restored their data after having paid the ransom, resulting in increased losses. The risk is also expensive. Ryuk ransoms frequently range from 15-40 BTC ($120,000 and $400,000). This is well above the average crypto-ransomware demands, which ZDNET estimates to be around $13,000. The alternative is to re-install the mission-critical elements of your IT environment. Without access to essential information backups, this requires a broad range of skill sets, well-coordinated team management, and the capability to work non-stop until the recovery project is finished.

Case Study: A Successful Ransomware Attack Recovery
A client contacted Progent after their organization was taken over by the Ryuk ransomware. Ryuk is thought to have been launched by North Korean state criminal gangs, suspected of adopting strategies exposed from the U.S. National Security Agency. Ryuk seeks specific organizations with little or no ability to sustain operational disruption and is among the most lucrative versions of ransomware. High publicized organizations include Data Resolution, a California-based info warehousing and cloud computing firm, and the Chicago Tribune. Progent's customer is a small manufacturing business based in the Chicago metro area and has about 500 employees. The Ryuk event had shut down all company operations and manufacturing capabilities. The majority of the client's data backups had been online at the start of the attack and were eventually encrypted. The client was pursuing financing for paying the ransom (exceeding two hundred thousand dollars) and praying for good luck, but in the end brought in Progent.
"I cannot tell you enough about the help Progent provided us throughout the most fearful period of (our) companyís survival. We would have paid the cyber criminals if not for the confidence the Progent experts afforded us. That you were able to get our e-mail system and important servers back online quicker than 1 week was earth shattering. Every single staff member I talked with or texted at Progent was laser focused on getting us operational and was working day and night to bail us out."
Progent worked hand in hand the client to rapidly identify and assign priority to the mission critical areas that needed to be addressed to make it possible to resume departmental functions:
To begin, Progent adhered to AV/Malware Processes penetration response industry best practices by stopping the spread and clearing up compromised systems. Progent then began the steps of rebuilding Windows Active Directory, the heart of enterprise systems built upon Microsoft technology. Exchange email will not operate without Active Directory, and the businessesí MRP system used Microsoft SQL Server, which depends on Windows AD for authentication to the data.
- Microsoft Active Directory
- Electronic Messaging
In less than 48 hours, Progent was able to restore Active Directory to its pre-attack state. Progent then accomplished setup and hard drive recovery on needed systems. All Exchange Server schema and attributes were usable, which greatly helped the rebuild of Exchange. Progent was able to locate local OST data files (Outlook Email Off-Line Folder Files) on staff desktop computers to recover email messages. A recent off-line backup of the customerís accounting software made it possible to return these required programs back online. Although major work was left to recover fully from the Ryuk damage, the most important services were returned to operations quickly:
"For the most part, the production manufacturing operation ran fairly normal throughout and we delivered all customer sales."
During the next few weeks important milestones in the restoration project were made in tight collaboration between Progent engineers and the customer:
- In-house web applications were returned to operation without losing any information.
- The MailStore Server exceeding 4 million archived messages was brought online and accessible to users.
- CRM/Customer Orders/Invoicing/Accounts Payable (AP)/Accounts Receivables/Inventory functions were 100 percent restored.
- A new Palo Alto 850 security appliance was brought on-line.
- Ninety percent of the user workstations were operational.
"A lot of what went on those first few days is nearly entirely a haze for me, but my management will not soon forget the urgency all of your team put in to give us our business back. Iíve entrusted Progent for at least 10 years, maybe more, and each time Progent has shined and delivered as promised. This event was a stunning achievement."
A potential business-ending disaster was avoided through the efforts of dedicated professionals, a broad array of subject matter expertise, and tight teamwork. Although in analyzing the event afterwards the ransomware attack detailed here should have been identified and blocked with advanced security technology and NIST Cybersecurity Framework best practices, user education, and appropriate security procedures for information protection and applying software patches, the fact remains that state-sponsored criminal cyber gangs from China, North Korea and elsewhere are relentless and are not going away. If you do fall victim to a crypto-ransomware virus, remember that Progent's team of professionals has a proven track record in ransomware virus blocking, remediation, and data recovery.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen and Tony (along with others that were helping), thank you for letting me get some sleep after we made it through the initial push. Everyone did an incredible effort, and if any of your team is in the Chicago area, dinner is the least I can do!"
