Ransomware : Your Worst IT Catastrophe
Crypto-Ransomware has become a modern cyberplague that poses an enterprise-level threat for businesses poorly prepared for an attack. Different versions of ransomware such as Reveton, CryptoWall, Locky, Syskey and MongoLock cryptoworms have been circulating for years and continue to inflict harm. Recent versions of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Lockbit or Egregor, along with additional as yet unnamed malware, not only do encryption of online data files but also infect many available system restores and backups. Data synched to cloud environments can also be encrypted. In a poorly architected system, it can make automated restoration impossible and basically knocks the network back to zero.
Getting back applications and information after a crypto-ransomware attack becomes a race against the clock as the targeted business struggles to stop lateral movement and remove the crypto-ransomware and to resume business-critical operations. Since crypto-ransomware requires time to spread, penetrations are frequently sprung on weekends and holidays, when successful penetrations typically take longer to uncover. This multiplies the difficulty of rapidly mobilizing and orchestrating a capable response team.
Progent provides an assortment of services for protecting enterprises from crypto-ransomware attacks. These include team member education to become familiar with and avoid phishing exploits, ProSight Active Security Monitoring for remote monitoring and management, along with installation of the latest generation security gateways with machine learning technology to intelligently detect and suppress day-zero cyber threats. Progent in addition offers the services of experienced ransomware recovery engineers with the skills and commitment to reconstruct a breached system as quickly as possible.
Progent's Crypto-Ransomware Restoration Services
After a crypto-ransomware attack, even paying the ransom in cryptocurrency does not provide any assurance that criminal gangs will provide the needed keys to decipher any of your files. Kaspersky Labs ascertained that seventeen percent of ransomware victims never recovered their data even after having sent off the ransom, resulting in additional losses. The risk is also expensive. Ryuk ransoms commonly range from fifteen to forty BTC ($120,000 and $400,000). This is significantly above the usual crypto-ransomware demands, which ZDNET determined to be approximately $13,000. The other path is to setup from scratch the key components of your IT environment. Without the availability of essential system backups, this requires a broad complement of IT skills, top notch project management, and the capability to work 24x7 until the job is completed.

Progent understands the urgency of working swiftly and together with a customerís management and IT resources to prioritize tasks and to get critical services back online as soon as possible.
Business Case Study: A Successful Ransomware Intrusion Restoration
A customer escalated to Progent after their network system was penetrated by Ryuk ransomware. Ryuk is believed to have been deployed by Northern Korean government sponsored criminal gangs, possibly adopting techniques exposed from Americaís National Security Agency. Ryuk seeks specific businesses with little ability to sustain operational disruption and is among the most profitable incarnations of ransomware. Well Known 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 headquartered in the Chicago metro area with around 500 staff members. The Ryuk penetration had frozen all company operations and manufacturing processes. Most of the client's system backups had been online at the time of the intrusion and were eventually encrypted. The client considered paying the ransom demand (in excess of $200,000) and wishfully thinking for the best, but ultimately called Progent.
"I canít tell you enough about the help Progent provided us throughout the most fearful time of (our) businesses life. We had little choice but to pay the hackers behind this attack if not for the confidence the Progent group provided us. That you could get our messaging and essential applications back into operation faster than 1 week was earth shattering. Every single expert I got help from or messaged at Progent was urgently focused on getting us operational and was working non-stop to bail us out."
Progent worked hand in hand the client to quickly identify and assign priority to the mission critical systems that needed to be addressed in order to resume company operations:
To begin, Progent followed ransomware event mitigation industry best practices by stopping the spread and clearing infected systems. Progent then started the work of restoring Microsoft Active Directory, the foundation of enterprise networks built on Microsoft technology. Microsoft Exchange Server messaging will not operate without AD, and the businessesí financials and MRP applications used Microsoft SQL Server, which needs Active Directory services for authentication to the data.
- Windows Active Directory
- Electronic Messaging
- Accounting and Manufacturing Software
Within 2 days, Progent was able to recover Active Directory to its pre-virus state. Progent then accomplished setup and hard drive recovery on the most important systems. All Exchange Server ties and attributes were intact, which greatly helped the restore of Exchange. Progent was also able to assemble non-encrypted OST files (Microsoft Outlook Offline Data Files) on team PCs to recover mail messages. A not too old off-line backup of the customerís financials/ERP software made it possible to recover these vital programs back available to users. Although a lot of work was left to recover totally from the Ryuk damage, critical systems were returned to operations rapidly:
"For the most part, the production line operation survived unscathed and we did not miss any customer orders."
Over the next couple of weeks key milestones in the restoration project were accomplished through close cooperation between Progent engineers and the customer:
- Self-hosted web sites were returned to operation without losing any information.
- The MailStore Microsoft Exchange Server exceeding 4 million historical emails was restored to operations and available for users.
- CRM/Product Ordering/Invoices/AP/Accounts Receivables/Inventory capabilities were 100 percent recovered.
- A new Palo Alto 850 firewall was set up.
- Nearly all of the user workstations were functioning as before the incident.
"A lot of what happened those first few days is nearly entirely a haze for me, but my management will not forget the commitment all of you put in to help get our business back. I have entrusted Progent for the past ten years, maybe more, and every time Progent has come through and delivered as promised. This event was a stunning achievement."
A likely enterprise-killing disaster was averted due to results-oriented professionals, a broad spectrum of IT skills, and tight teamwork. Although in analyzing the event afterwards the crypto-ransomware attack detailed here should have been identified and prevented with up-to-date cyber security technology solutions and NIST Cybersecurity Framework best practices, team training, and appropriate incident response procedures for information protection and keeping systems up to date with security patches, the fact is that government-sponsored criminal cyber gangs from Russia, North Korea and elsewhere are relentless and are an ongoing threat. If you do fall victim to a crypto-ransomware incident, feel confident that Progent's team of professionals has proven experience in ransomware virus blocking, removal, and data recovery.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Tony and Chris (and any others who were involved), thank you for making it so I could get some sleep after we made it past the most critical parts. Everyone did an fabulous effort, and if any of your team is around the Chicago area, dinner is on me!"
