Crypto-Ransomware : Your Worst IT Catastrophe
Ransomware has become a too-frequent cyber pandemic that represents an existential danger for businesses of all sizes vulnerable to an attack. Versions of crypto-ransomware like the Reveton, Fusob, Locky, SamSam and MongoLock cryptoworms have been circulating for years and continue to cause destruction. Newer versions of crypto-ransomware like Ryuk, Maze, Sodinokibi, Netwalker, Snatch and Nephilim, as well as more as yet unnamed newcomers, not only do encryption of on-line data but also infiltrate any available system restores and backups. Information synched to the cloud can also be encrypted. In a poorly designed environment, it can render automated restoration useless and basically knocks the network back to square one.
Retrieving applications and information after a crypto-ransomware event becomes a sprint against the clock as the targeted business tries its best to stop lateral movement and cleanup the ransomware and to resume mission-critical activity. Because crypto-ransomware takes time to move laterally, penetrations are frequently launched during weekends and nights, when successful penetrations are likely to take more time to uncover. This multiplies the difficulty of rapidly mobilizing and orchestrating an experienced response team.
Progent offers an assortment of services for securing Miami Beach enterprises from ransomware penetrations. These include team training to help recognize and avoid phishing attempts, ProSight Active Security Monitoring (ASM) for remote monitoring and management, plus setup and configuration of next-generation security gateways with machine learning capabilities to intelligently discover and suppress day-zero cyber threats. Progent in addition can provide the services of expert crypto-ransomware recovery engineers with the track record and commitment to rebuild a compromised environment as soon as possible.
Progent's Ransomware Restoration Help
After a crypto-ransomware event, sending the ransom in cryptocurrency does not ensure that cyber hackers will return the needed keys to decipher any or all of your data. Kaspersky Labs ascertained that 17% of ransomware victims never restored their data even after having paid the ransom, resulting in additional losses. The risk is also costly. Ryuk ransoms frequently range from 15-40 BTC ($120,000 and $400,000). This is greatly higher than the typical ransomware demands, which ZDNET determined to be in the range of $13,000 for small businesses. The other path is to piece back together the essential parts of your IT environment. Without access to complete information backups, this calls for a broad complement of skills, top notch project management, and the capability to work continuously until the job is over.
For decades, Progent has offered expert IT services for companies across the U.S. and has achieved Microsoft's Gold Partnership certification in the Datacenter and Cloud Productivity competencies.

Progent understands the importance of acting quickly and together with a customerís management and Information Technology staff to assign priority to tasks and to put key applications back on-line as soon as possible.
Case Study: A Successful Ransomware Intrusion Response
A business escalated to Progent after their company was taken over by the Ryuk ransomware. Ryuk is generally considered to have been created by North Korean state sponsored hackers, possibly using algorithms exposed from the U.S. National Security Agency. Ryuk goes after specific organizations with little ability to sustain operational disruption and is among the most lucrative incarnations of crypto-ransomware. High publicized organizations include Data Resolution, a California-based information warehousing and cloud computing company, and the Chicago Tribune. Progent's client is a regional manufacturing business located in Chicago with about 500 workers. The Ryuk attack had shut down all business operations and manufacturing processes. The majority of the client's system backups had been directly accessible at the time of the intrusion and were eventually encrypted. The client was actively seeking loans for paying the ransom demand (in excess of two hundred thousand dollars) and wishfully thinking for good luck, but ultimately utilized Progent.
"I cannot thank you enough in regards to the expertise Progent provided us throughout the most fearful time of (our) businesses survival. We most likely would have paid the cybercriminals if it wasnít for the confidence the Progent team provided us. That you could get our messaging and production applications back quicker than seven days was amazing. Every single expert I interacted with or messaged at Progent was hell bent on getting us operational and was working 24 by 7 to bail us out."
Progent worked hand in hand the customer to quickly understand and prioritize the essential areas that had to be restored to make it possible to continue company functions:
To begin, Progent adhered to ransomware incident response best practices by halting the spread and removing active viruses. Progent then began the process of restoring Microsoft Active Directory, the core of enterprise environments built upon Microsoft Windows Server technology. Exchange messaging will not operate without Windows AD, and the customerís financials and MRP system utilized SQL Server, which depends on Active Directory for access to the data.
- Microsoft Active Directory
- Microsoft Exchange Email
- Accounting and Manufacturing Software
Within two days, Progent was able to restore Active Directory services to its pre-virus state. Progent then completed setup and hard drive recovery of key servers. All Microsoft Exchange Server ties and attributes were usable, which facilitated the restore of Exchange. Progent was able to collect non-encrypted OST files (Outlook Offline Data Files) on team workstations to recover email data. A recent offline backup of the client's financials/MRP systems made them able to recover these required programs back available to users. Although major work still had to be done to recover completely from the Ryuk damage, the most important systems were restored quickly:
"For the most part, the production operation showed little impact and we produced all customer shipments."
Throughout the next month critical milestones in the recovery process were made in tight cooperation between Progent consultants and the customer:
- In-house web sites were returned to operation with no loss of data.
- The MailStore Server containing more than 4 million historical emails was brought online and available for users.
- CRM/Customer Orders/Invoicing/Accounts Payable (AP)/Accounts Receivables (AR)/Inventory Control capabilities were fully operational.
- A new Palo Alto 850 security appliance was installed and configured.
- Ninety percent of the user workstations were being used by staff.
"A lot of what happened those first few days is nearly entirely a fog for me, but we will not forget the countless hours each of you accomplished to help get our company back. Iíve been working together with Progent for the past 10 years, maybe more, and every time Progent has shined and delivered as promised. This event was a stunning achievement."
A likely business catastrophe was averted through the efforts of top-tier experts, a wide range of IT skills, and close collaboration. Although upon completion of forensics the ransomware attack described here should have been identified and disabled with advanced cyber security technology solutions and security best practices, user training, and well thought out security procedures for data protection and proper patching controls, the reality remains that state-sponsored criminal cyber gangs from Russia, North Korea and elsewhere are tireless and will continue. If you do fall victim to a ransomware incursion, feel confident that Progent's roster of professionals has substantial experience in ransomware virus blocking, removal, and data recovery.
"So, to Darrin, Matt, Dan, Claude, Jesse, Arnaud, Allen, Tony and Chris (along with others that were contributing), thanks very much for making it so I could get some sleep after we got past the most critical parts. All of you did an incredible effort, and if anyone is visiting the Chicago area, dinner is the least I can do!"
