Crypto-Ransomware : Your Worst Information Technology Disaster
Crypto-Ransomware has become a too-frequent cyber pandemic that presents an enterprise-level threat for businesses vulnerable to an attack. Versions of crypto-ransomware such as Reveton, CryptoWall, Locky, Syskey and MongoLock cryptoworms have been around for years and still cause harm. More recent strains of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Snatch or Egregor, as well as additional unnamed newcomers, not only do encryption of online data files but also infiltrate most available system restores and backups. Files synchronized to the cloud can also be rendered useless. In a vulnerable system, it can render any restore operations hopeless and basically sets the entire system back to zero.
Getting back online applications and data following a crypto-ransomware intrusion becomes a race against time as the targeted business tries its best to contain and remove the virus and to resume enterprise-critical operations. Due to the fact that ransomware needs time to spread, assaults are usually sprung on weekends, when successful penetrations in many cases take longer to discover. This compounds the difficulty of promptly marshalling and orchestrating a knowledgeable mitigation team.
Progent provides an assortment of solutions for protecting enterprises from crypto-ransomware attacks. These include staff training to become familiar with and avoid phishing exploits, ProSight Active Security Monitoring for remote monitoring and management, plus deployment of next-generation security gateways with machine learning capabilities to automatically discover and quarantine zero-day cyber attacks. Progent in addition provides the services of expert ransomware recovery consultants with the track record and perseverance to reconstruct a breached network as soon as possible.
Progent's Crypto-Ransomware Restoration Help
Following a ransomware penetration, sending the ransom demands in cryptocurrency does not ensure that criminal gangs will respond with the needed keys to unencrypt any or all of your data. Kaspersky Labs 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 commonly range from fifteen to forty BTC ($120,000 and $400,000). This is well above the usual ransomware demands, which ZDNET estimates to be around $13,000. The other path is to piece back together the mission-critical elements of your Information Technology environment. Absent access to full data backups, this calls for a wide range of skill sets, professional project management, and the ability to work continuously until the task is finished.

Progent's security group has state-of-the-art project management tools to orchestrate the complicated recovery process. Progent knows the importance of working quickly and together with a client's management and Information Technology team members to prioritize tasks and to get the most important services back on-line as soon as possible.
Case Study: A Successful Crypto-Ransomware Incident Recovery
A client escalated to Progent after their network was taken over by Ryuk ransomware virus. Ryuk is generally considered to have been deployed by North Korean state criminal gangs, possibly adopting approaches leaked from the U.S. NSA organization. Ryuk targets specific businesses with little ability to sustain disruption and is among the most lucrative versions of ransomware malware. Headline organizations include Data Resolution, a California-based information warehousing and cloud computing business, and the Chicago Tribune. Progent's customer is a single-location manufacturing business headquartered in the Chicago metro area with around 500 staff members. The Ryuk event had paralyzed all essential operations and manufacturing processes. Most of the client's information backups had been on-line at the time of the intrusion and were damaged. The client was evaluating paying the ransom (in excess of two hundred thousand dollars) and wishfully thinking for good luck, but ultimately engaged Progent.
"I cannot say enough about the expertise Progent provided us throughout the most critical period of (our) businesses existence. We would have paid the hackers behind this attack if it wasnít for the confidence the Progent group afforded us. The fact that you were able to get our messaging and essential applications back online quicker than 1 week was incredible. Every single expert I spoke to or e-mailed at Progent was absolutely committed on getting our company operational and was working at all hours to bail us out."
Progent worked together with the client to quickly understand and prioritize the critical elements that had to be restored to make it possible to restart company functions:
To begin, Progent adhered to ransomware event response industry best practices by stopping lateral movement and performing virus removal steps. Progent then started the task of rebuilding Windows Active Directory, the key technology of enterprise systems built upon Microsoft Windows technology. Exchange email will not operate without AD, and the customerís financials and MRP applications used SQL Server, which depends on Active Directory services for security authorization to the data.
- Active Directory (AD)
Within 2 days, Progent was able to re-build Active Directory to its pre-intrusion state. Progent then helped perform reinstallations and hard drive recovery on critical applications. All Exchange Server data and configuration information were usable, which greatly helped the restore of Exchange. Progent was also able to locate local OST data files (Microsoft Outlook Offline Folder Files) on staff PCs and laptops to recover mail data. A recent offline backup of the businesses accounting systems made them able to restore these vital programs back online for users. Although a large amount of work needed to be completed to recover completely from the Ryuk event, the most important services were recovered quickly:
"For the most part, the assembly line operation survived unscathed and we made all customer shipments."
Throughout the following month important milestones in the restoration process were achieved through close cooperation between Progent team members and the client:
- Self-hosted web applications were restored with no loss of information.
- The MailStore Exchange Server exceeding 4 million historical messages was brought on-line and accessible to users.
- CRM/Customer Orders/Invoicing/Accounts Payable (AP)/Accounts Receivables/Inventory Control modules were completely recovered.
- A new Palo Alto 850 firewall was set up.
- Most of the user PCs were back into operation.
"So much of what occurred those first few days is mostly a fog for me, but we will not soon forget the countless hours each of the team accomplished to help get our business back. Iíve been working together with Progent for the past ten years, maybe more, and each time I needed help Progent has outperformed my expectations and delivered as promised. This event was a stunning achievement."
A likely company-ending catastrophe was evaded by hard-working experts, a wide array of technical expertise, and tight teamwork. Although in retrospect the ransomware incident described here would have been identified and prevented with current security technology solutions and NIST Cybersecurity Framework best practices, staff education, and properly executed incident response procedures for information backup and keeping systems up to date with security patches, the fact is that state-sponsored cyber criminals from Russia, North Korea and elsewhere are tireless and will continue. If you do fall victim to a ransomware virus, remember that Progent's team of professionals has a proven track record in crypto-ransomware virus defense, removal, and file recovery.
"So, to Darrin, Matt, Aaron, Dan, Claude, Jesse, Arnaud, Allen and Tony (and any others that were involved), thanks very much for making it so I could get some sleep after we made it past the first week. Everyone did an amazing effort, and if any of your guys is around the Chicago area, dinner is the least I can do!"
