Crypto-Ransomware : Your Crippling Information Technology Nightmare
Ransomware has become a modern cyber pandemic that presents an existential threat for organizations poorly prepared for an assault. Versions of ransomware like the Dharma, CryptoWall, Bad Rabbit, NotPetya and MongoLock cryptoworms have been running rampant for years and still cause havoc. Modern variants of ransomware like Ryuk and Hermes, along with more unnamed malware, not only encrypt on-line critical data but also infect any configured system restores and backups. Information synched to the cloud can also be encrypted. In a poorly designed environment, this can make automated restoration useless and effectively sets the network back to square one.
Getting back online applications and data after a ransomware intrusion becomes a sprint against the clock as the targeted organization fights to stop the spread and eradicate the crypto-ransomware and to restore enterprise-critical activity. Due to the fact that ransomware needs time to move laterally, assaults are often sprung at night, when successful penetrations may take more time to uncover. This compounds the difficulty of rapidly marshalling and coordinating a capable mitigation team.
Progent makes available an assortment of help services for protecting businesses from ransomware events. Among these are team education to help recognize and not fall victim to phishing scams, ProSight Active Security Monitoring for remote monitoring and management, along with deployment of next-generation security gateways with machine learning capabilities to intelligently identify and quarantine day-zero cyber attacks. Progent also offers the services of seasoned ransomware recovery professionals with the track record and commitment to restore a compromised environment as rapidly as possible.
Progent's Ransomware Recovery Help
Soon after a ransomware penetration, sending the ransom in Bitcoin cryptocurrency does not provide any assurance that cyber criminals will respond with the keys to decipher any or all of your files. Kaspersky determined that 17% of ransomware victims never recovered their data after having sent off the ransom, resulting in increased losses. The gamble is also costly. Ryuk ransoms commonly range from 15-40 BTC ($120,000 and $400,000). This is well above the average crypto-ransomware demands, which ZDNET determined to be approximately $13,000. The fallback is to re-install the key components of your Information Technology environment. Absent the availability of essential system backups, this calls for a broad range of skill sets, well-coordinated project management, and the capability to work 24x7 until the job is complete.

Case Study: A Successful Ransomware Intrusion Recovery
A small business engaged Progent after their network system was brought down by Ryuk ransomware. Ryuk is generally considered to have been deployed by North Korean government sponsored hackers, suspected of adopting techniques exposed from Americaís NSA organization. Ryuk goes after specific companies with little room for disruption and is one of the most profitable instances of crypto-ransomware. Major organizations include Data Resolution, a California-based data warehousing and cloud computing business, and the Chicago Tribune. Progent's client is a single-location manufacturing business based in Chicago and has around 500 staff members. The Ryuk attack had shut down all business operations and manufacturing capabilities. The majority of the client's backups had been online at the beginning of the attack and were destroyed. The client was evaluating paying the ransom (exceeding $200,000) and wishfully thinking for good luck, but ultimately brought in Progent.
"I canít speak enough in regards to the care Progent provided us throughout the most fearful time of (our) companyís existence. We may have had to pay the Hackers if not for the confidence the Progent team gave us. That you were able to get our messaging and important servers back online faster than seven days was incredible. Each person I got help from or communicated with at Progent was urgently focused on getting us back on-line and was working 24 by 7 on our behalf."
Progent worked hand in hand the customer to rapidly assess and prioritize the critical systems that needed to be recovered in order to resume departmental functions:
To begin, Progent followed ransomware penetration mitigation best practices by stopping lateral movement and performing virus removal steps. Progent then started the task of bringing back online Microsoft AD, the heart of enterprise environments built upon Microsoft Windows Server technology. Microsoft Exchange messaging will not operate without AD, and the businessesí financials and MRP system leveraged SQL Server, which depends on Active Directory for authentication to the data.
- Windows Active Directory
- Electronic Messaging
- MRP System
In less than 2 days, Progent was able to restore Active Directory to its pre-intrusion state. Progent then completed rebuilding and hard drive recovery of the most important systems. All Exchange schema and configuration information were intact, which greatly helped the rebuild of Exchange. Progent was also able to collect non-encrypted OST files (Outlook Off-Line Folder Files) on staff workstations and laptops in order to recover mail data. A recent off-line backup of the customerís accounting/ERP systems made them able to restore these required services back online. Although major work still had to be done to recover completely from the Ryuk damage, core services were restored quickly:
"For the most part, the assembly line operation was never shut down and we produced all customer orders."
Over the next couple of weeks critical milestones in the restoration process were completed through close collaboration between Progent engineers and the client:
- In-house web applications were restored without losing any information.
- The MailStore Microsoft Exchange Server exceeding 4 million archived messages was restored to operations and accessible to users.
- CRM/Customer Orders/Invoices/Accounts Payable (AP)/Accounts Receivables (AR)/Inventory capabilities were 100 percent operational.
- A new Palo Alto Networks 850 security appliance was installed and configured.
- 90% of the desktops and laptops were functioning as before the incident.
"So much of what was accomplished those first few days is mostly a fog for me, but I will not soon forget the care each of you put in to give us our company back. I have entrusted Progent for the past 10 years, maybe more, and every time Progent has outperformed my expectations and delivered as promised. This situation was a Herculean accomplishment."
A possible business-ending disaster was averted with top-tier experts, a wide range of knowledge, and tight teamwork. Although in hindsight the ransomware virus attack detailed here should have been identified and blocked with current security technology and security best practices, staff education, and well thought out security procedures for data protection and applying software patches, the fact is that government-sponsored criminal cyber gangs from China, North Korea and elsewhere are tireless and will continue. If you do get hit by a ransomware attack, feel confident that Progent's team of professionals has substantial experience in ransomware virus blocking, mitigation, and data restoration.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Tony and Chris (along with others that were involved), thanks very much for making it so I could get rested after we got through the most critical parts. Everyone did an incredible effort, and if anyone is around the Chicago area, dinner is the least I can do!"
