Crypto-Ransomware : Your Feared IT Nightmare
Ransomware has become a modern cyberplague that represents an enterprise-level danger for businesses of all sizes unprepared for an assault. Different iterations of ransomware like the Reveton, CryptoWall, Locky, Syskey and MongoLock cryptoworms have been around for a long time and continue to inflict harm. The latest strains of ransomware like Ryuk, Maze, Sodinokibi, Netwalker, Lockbit or Egregor, plus more unnamed viruses, not only do encryption of online critical data but also infect most configured system restores and backups. Information synched to cloud environments can also be encrypted. In a vulnerable system, this can make any recovery useless and basically knocks the network back to zero.
Getting back on-line services and data following a ransomware intrusion becomes a race against time as the targeted organization struggles to contain and cleanup the ransomware and to restore enterprise-critical activity. Because ransomware takes time to spread, attacks are often sprung on weekends, when successful penetrations tend to take longer to discover. This compounds the difficulty of quickly mobilizing and coordinating a qualified mitigation team.
Progent provides an assortment of help services for protecting businesses from crypto-ransomware penetrations. These include staff training to help identify and avoid phishing attempts, ProSight Active Security Monitoring for remote monitoring and management, in addition to setup and configuration of the latest generation security solutions with AI technology to quickly detect and suppress zero-day cyber attacks. Progent also provides the services of experienced ransomware recovery engineers with the talent and commitment to reconstruct a compromised network as urgently as possible.
Progent's Ransomware Recovery Support Services
Following a crypto-ransomware attack, sending the ransom demands in cryptocurrency does not ensure that merciless criminals will return the needed keys to unencrypt any of your files. Kaspersky estimated that 17% of crypto-ransomware victims never restored their files even after having paid the ransom, resulting in additional losses. The risk is also expensive. Ryuk ransoms often range from fifteen to forty BTC ($120,000 and $400,000). This is well above the usual ransomware demands, which ZDNET determined to be approximately $13,000. The fallback is to piece back together the mission-critical elements of your Information Technology environment. Without the availability of full information backups, this requires a wide range of skill sets, top notch project management, and the willingness to work continuously until the job is done.

Progent knows the urgency of acting swiftly and in unison with a client's management and Information Technology staff to prioritize tasks and to get critical systems back on line as soon as possible.
Case Study: A Successful Ransomware Penetration Recovery
A small business engaged Progent after their organization was crashed by Ryuk crypto-ransomware. Ryuk is believed to have been launched by North Korean government sponsored cybercriminals, suspected of adopting strategies exposed from Americaís NSA organization. Ryuk seeks specific businesses with limited tolerance for operational disruption and is among the most lucrative instances of ransomware. High publicized organizations include Data Resolution, a California-based data warehousing and cloud computing company, and the Chicago Tribune. Progent's customer is a single-location manufacturer based in the Chicago metro area with around 500 staff members. The Ryuk intrusion had shut down all essential operations and manufacturing processes. The majority of the client's backups had been online at the start of the attack and were destroyed. The client was taking steps for paying the ransom (exceeding two hundred thousand dollars) and praying for the best, but in the end reached out to Progent.
"I canít say enough about the help Progent gave us throughout the most stressful time of (our) businesses survival. We most likely would have paid the cyber criminals if not for the confidence the Progent experts gave us. That you could get our e-mail system and production applications back online quicker than five days was incredible. Every single expert I worked with or messaged at Progent was totally committed on getting us back online and was working day and night on our behalf."
Progent worked with the client to rapidly determine and assign priority to the mission critical areas that had to be addressed to make it possible to restart company operations:
To begin, Progent followed ransomware event response industry best practices by isolating and clearing infected systems. Progent then initiated the process of restoring Microsoft AD, the key technology of enterprise environments built upon Microsoft technology. Microsoft Exchange Server messaging will not work without AD, and the customerís accounting and MRP applications leveraged SQL Server, which depends on Active Directory services for authentication to the data.
- Active Directory
- Microsoft Exchange Email
In less than 2 days, Progent was able to recover Active Directory services to its pre-penetration state. Progent then charged ahead with setup and hard drive recovery of needed systems. All Exchange Server ties and attributes were intact, which accelerated the rebuild of Exchange. Progent was able to locate non-encrypted OST data files (Outlook Offline Data Files) on team desktop computers in order to recover mail data. A not too old off-line backup of the businesses financials/ERP systems made it possible to recover these essential services back online. Although a lot of work was left to recover fully from the Ryuk damage, core systems were returned to operations quickly:
"For the most part, the assembly line operation showed little impact and we made all customer orders."
Throughout the following couple of weeks important milestones in the recovery project were made in close collaboration between Progent team members and the client:
- Self-hosted web sites were restored without losing any data.
- The MailStore Microsoft Exchange Server exceeding four million historical messages was brought on-line and accessible to users.
- CRM/Orders/Invoicing/Accounts Payable (AP)/Accounts Receivables/Inventory Control modules were fully restored.
- A new Palo Alto Networks 850 firewall was installed and configured.
- Ninety percent of the user desktops and notebooks were back into operation.
"A lot of what transpired in the early hours is nearly entirely a haze for me, but my management will not soon forget the commitment all of you accomplished to give us our company back. I have entrusted Progent for at least 10 years, maybe more, and each time Progent has shined and delivered as promised. This situation was a life saver."
A probable business-killing catastrophe was evaded with top-tier experts, a broad array of subject matter expertise, and tight collaboration. Although in hindsight the ransomware incident described here would have been identified and disabled with modern cyber security solutions and NIST Cybersecurity Framework best practices, user and IT administrator education, and well thought out security procedures for information protection and proper patching controls, the fact remains that government-sponsored hackers from Russia, North Korea and elsewhere are relentless and are not going away. If you do fall victim to a ransomware incident, remember that Progent's roster of professionals has proven experience in ransomware virus blocking, removal, and file restoration.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen and Chris (and any others who were helping), thanks very much for allowing me to get some sleep after we made it past the initial fire. Everyone did an incredible job, and if any of your team is in the Chicago area, dinner is on me!"
