Ransomware : Your Crippling IT Disaster
Ransomware has become an escalating cyberplague that poses an extinction-level danger for organizations poorly prepared for an attack. Different versions of crypto-ransomware such as Dharma, WannaCry, Locky, NotPetya and MongoLock cryptoworms have been replicating for many years and still cause havoc. More recent variants of ransomware such as Ryuk and Hermes, along with daily unnamed malware, not only encrypt online information but also infect all accessible system restores and backups. Files replicated to off-site disaster recovery sites can also be rendered useless. In a vulnerable system, it can make automated restore operations impossible and effectively sets the network back to square one.
Retrieving programs and data after a ransomware intrusion becomes a sprint against time as the victim struggles to contain and cleanup the crypto-ransomware and to restore business-critical operations. Due to the fact that ransomware requires time to move laterally, penetrations are usually sprung on weekends and holidays, when penetrations tend to take longer to discover. This compounds the difficulty of quickly mobilizing and coordinating a qualified response team.
Progent provides a variety of services for securing enterprises from ransomware penetrations. Among these are staff training to help identify and not fall victim to phishing scams, ProSight Active Security Monitoring (ASM) for remote monitoring and management, along with deployment of next-generation security appliances with machine learning technology to automatically detect and disable new cyber threats. Progent also provides the assistance of expert ransomware recovery engineers with the skills and perseverance to rebuild a breached network as rapidly as possible.
Progent's Ransomware Restoration Services
Subsequent to a ransomware attack, even paying the ransom in Bitcoin cryptocurrency does not ensure that cyber hackers will respond with the needed keys to decrypt all your data. Kaspersky Labs estimated that 17% of crypto-ransomware victims never recovered their information even after having sent off the ransom, resulting in more losses. The risk is also very costly. Ryuk ransoms often range from 15-40 BTC ($120,000 and $400,000). This is greatly above the average ransomware demands, which ZDNET estimates to be around $13,000. The other path is to re-install the mission-critical components of your IT environment. Without access to full system backups, this calls for a broad range of skills, top notch team management, and the willingness to work 24x7 until the job is finished.

Client Story: A Successful Ransomware Attack Recovery
A client hired Progent after their network system was taken over by Ryuk crypto-ransomware. Ryuk is thought to have been deployed by Northern Korean state cybercriminals, suspected of adopting technology leaked from the U.S. National Security Agency. Ryuk targets specific companies with little or no room for disruption and is among the most lucrative incarnations of ransomware malware. Major victims include Data Resolution, a California-based info warehousing and cloud computing firm, and the Chicago Tribune. Progent's client is a regional manufacturing business headquartered in Chicago and has around 500 workers. The Ryuk intrusion had disabled all company operations and manufacturing processes. The majority of the client's system backups had been on-line at the time of the attack and were encrypted. The client was taking steps for paying the ransom demand (exceeding $200,000) and praying for good luck, but ultimately brought in Progent.
"I cannot thank you enough about the expertise Progent gave us during the most stressful time of (our) companyís survival. We had little choice but to pay the cyber criminals except for the confidence the Progent team gave us. The fact that you could get our messaging and essential applications back faster than one week was incredible. Every single person I interacted with or messaged at Progent was totally committed on getting my company operational and was working at all hours on our behalf."
Progent worked together with the client to rapidly identify and assign priority to the key services that had to be restored in order to restart company functions:
To start, Progent followed AV/Malware Processes incident response best practices by stopping the spread and removing active viruses. Progent then began the task of rebuilding Windows Active Directory, the foundation of enterprise environments built on Microsoft technology. Microsoft Exchange Server messaging will not function without Active Directory, and the businessesí accounting and MRP software utilized Microsoft SQL Server, which requires Active Directory for access to the databases.
- Windows Active Directory
- Electronic Mail
- MRP System
Within two days, Progent was able to recover Active Directory to its pre-attack state. Progent then performed rebuilding and hard drive recovery on critical servers. All Exchange Server data and attributes were intact, which accelerated the rebuild of Exchange. Progent was also able to locate intact OST files (Microsoft Outlook Offline Data Files) on staff PCs and laptops in order to recover email information. A not too old offline backup of the client's accounting systems made them able to recover these vital applications back on-line. Although a large amount of work needed to be completed to recover totally from the Ryuk damage, the most important systems were returned to operations quickly:
"For the most part, the production line operation never missed a beat and we produced all customer orders."
Throughout the following month important milestones in the restoration process were accomplished through tight collaboration between Progent team members and the customer:
- In-house web sites were brought back up without losing any data.
- The MailStore Exchange Server containing more than 4 million archived emails was spun up and available for users.
- CRM/Customer Orders/Invoicing/Accounts Payable/AR/Inventory Control modules were 100% recovered.
- A new Palo Alto 850 firewall was installed.
- Nearly all of the user PCs were functioning as before the incident.
"A huge amount of what was accomplished in the initial days is nearly entirely a blur for me, but our team will not soon forget the commitment all of you put in to help get our company back. I have trusted Progent for at least 10 years, maybe more, and each time I needed help Progent has shined and delivered. This time was a stunning achievement."
A potential enterprise-killing catastrophe was evaded through the efforts of dedicated professionals, a broad spectrum of knowledge, and close teamwork. Although in post mortem the crypto-ransomware incident detailed here could have been disabled with current security technology and security best practices, user training, and properly executed security procedures for data backup and proper patching controls, the reality is that state-sponsored cybercriminals from Russia, North Korea and elsewhere are tireless and are not going away. If you do fall victim to a crypto-ransomware virus, remember that Progent's roster of professionals has a proven track record in ransomware virus defense, cleanup, and file recovery.
"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others who were helping), thank you for letting me get some sleep after we made it through the initial fire. All of you did an impressive job, and if anyone that helped is visiting the Chicago area, dinner is my treat!"
