"On average, there is a ransomware attack every 11 seconds. 51% of victims pay the ransom at an average of $200K per attack, amounting to $20B in total cost." (source)
“In North America, ransomware attacks affected nearly 7-in-10 companies in 2020” (source)
What is an example of a Ransomware attack? (Click here)
"Bad Rabbit is a 2017 ransomware attack that spread using a method called a 'drive-by' attack, where insecure websites are targeted and used to carry out an attack. .Bad Rabbit used a fake request to install Adobe Flash as a malware dropper to spread its infection." Five of the most significant ransomware attacks in 2020 include: Maze, REvil, Ryuk, Tycoon, NetWalker.
How do I get Ransomware? (Click here)
"There are several different ways that ransomware can infect your computer. One of the most common methods today is through malicious spam (or malspam), which is unsolicited email that is used to deliver malware. The email might include booby-trapped attachments, such as PDFs or Word documents."
What is the trend for Ransomware? (Click here)
"According to Trend Micro, computer criminals continue to show an interest in ransomware, as well as cheap offerings associated with deepfake services on underground web marketplaces. Malwarebytes noted that malicious actors could ultimately combine these two threats together into “deepfake ransomware” attacks". Aug 4, 2020
How much do cyber criminals typically ask for as a ransom payment?? (Click here)
"The data shows that 20 percent of compromised organizations have paid ransoms of more than $40,000, and 25 percent have paid between $20,000 and $40,000. Those numbers are far higher than what consumers typically pay, which is usually in the range of $500-$1,000, depending on the ransomware variant."
What percentage of victims pay the Ransomware? (Click here)
"In 2018, 39 percent of ransomware victims paid the ransom. In 2019, that number rose to 45 percent. Today, as many as 58 percent of ransomware victims, from every industry, have paid ransom. Apr 3, 2020"
Can Ransomware be removed?? (Click here)
"Every filecoder has its own method of encryption, which means you can't simply remove it like other forms of malware. To avoid being studied and decrypted, most ransomware programs delete themselves after a set period of time. Sep 25, 2019"

So what is the key lesson Mendoza would say that other organizations need to take away from Spectra Logic's experience? "You've got to limit your attack blast radius. Backup your data in multiple locations on multiple mediums and the key is to air-gap it. Whether it's physical air-gap or virtual air-gap, you've got to put a wall between an attack and your data," he said."

Try this one weird trick Russian hackers hate...
"In a Twitter discussion last week on ransomware attacks, KrebsOnSecurity noted that virtually all ransomware strains have a built-in failsafe designed to cover the backsides of the malware purveyors: They simply will not install on a Microsoft Windows computer that already has one of many types of virtual keyboards installed — such as Russian or Ukrainian. So many readers had questions in response to the tweet that I thought it was worth a blog post exploring this one weird cyber defense trick."
"Simply put, countless malware strains will check for the presence of one of these languages on the system, and if they’re detected the malware will exit and fail to install."
“This is for their legal protection,” Nixon said. “Installing a Cyrillic keyboard, or changing a specific registry entry to say ‘RU’, and so forth, might be enough to convince malware that you are Russian and off limits. This can technically be used as a ‘vaccine’ against Russian malware.”
"To install a different keyboard language on a Windows 10 computer the old fashioned way, hit the Windows key and X at the same time, then select Settings, and then select “Time and Language.” Select Language, and then scroll down and you should see an option to install another character set. Pick one, and the language should be installed the next time you reboot. Again, if for some reason you need to toggle between languages, Windows+Spacebar is your friend."
Here are few recommendations for remediation that should be at your disposal should a ransomware incident happen...
Veeam Support: There is a special group within the Veeam support organization that has specific operations to guide customers through data restores in ransomware incidents. You do not want to put your backups at risk; they are critical to your ability to recover.
Communications first: In disasters of any type, communication becomes one of the first challenges to achieve. Have a plan for how to communicate to the right individuals out-of-band. This would include group text lists, phone numbers or other mechanisms that are commonly used for on-call mechanisms but expanded for an entire IT operations groups.
Experts: Have a list of security, incident response, identity management, etc. experts that are ready to be contacted if needed. They can be within the organization or external experts. If a Veeam service provider is used, there are additional value adds to their base offering that can be considered (such as Veeam Cloud Connect Insider Protection). Chain of decision: One of the hardest parts of recovering from a disaster is decision authority. Who makes the call to restore, to fail over, etc.? Have business discussions about this beforehand.
Ready to restore: When the conditions are right to restore, implement additional safety checks before putting systems on the network again. Part of those tips are explained earlier in this document but additional steps can include restoring with network access disabled for a final check.
Restore options: Depending on the situation, maybe a whole VM recovery is best. Possibly a file-level recovery makes sense. Familiarity with your recovery options will help greatly.
Restore safely: As explained earlier, Veeam Secure Restore will trigger an antivirus scan of the image before the restore completes. Use the latest anti-virus and malware definitions and perhaps an additional tool to ensure a threat is not reintroduced.
Force password resets: Users don’t like this but implement a sweeping forced change of passwords. This will reduce the threat propagation surface area.
What is the "Internet Crime Complaint Center IC3"? (Click Here)
You should file a complaint with the IC3 if you believe you have been the victim of an Internet crime or if you want to file on behalf of another person you believe has been such a victim.
"IC3's purpose is to serve as a central hub to receive, develop, and refer criminal complaints regarding the rapidly expanding occurrences of Internet crime. The IC3 gives victims a convenient and easy-to-use reporting mechanism that alerts authorities of suspected criminal or civil violations on the Internet. IC3 develops leads and notifies law enforcement agencies at the federal, state, local and international level."
Companies can also contact their local FBI field office. It will ask for the following information...
Date of Ransomware attack
How the infection occurred
Amount paid, if any
The ransomware variant
Information about your company, such as industry, size, etc...
Victim impact statement; and
Losses due to the ransomware attack.
What are the "US-CERT Federal Incident Notification Guidelines"? (Click Here)
Companies can also report ransomware to CISA. Like reporting to the FBI, CISA has specific ransomware reporting requirements...
"Agencies must report information security incidents, where the confidentiality, integrity, or availability of a federal information system of a civilian Executive Branch agency is potentially compromised, to the NCCIC/US-CERT with the required data elements, as well as any other available information, within one hour of being identified by the agency’s top-level Computer Security Incident Response Team (CSIRT), Security Operations Center (SOC), or information technology department. In some cases, it may not be feasible to have complete and validated information for the section below (Submitting Incident Notifications) prior to reporting. Agencies should provide their best estimate at the time of notification and report updated information as it becomes available. Events that have been found by the reporting agency not to impact confidentiality, integrity or availability may be reported voluntarily to US-CERT; however, they may not be included in the FISMA Annual Report to Congress."
"The Cybersecurity and Infrastructure Security Agency (CISA) is a standalone United States federal agency, an operational component under Department of Homeland Security (DHS) oversight. Its activities are a continuation of the National Protection and Programs Directorate (NPPD). CISA was established on November 16, 2018 when President Donald Trump signed into law the Cybersecurity and Infrastructure Security Agency Act of 2018."
Identify the current level of impact on agency functions or services.
Identify the type of information lost, compromised or corrupted.
Estimate the scope of time and resources needed to recover from the incident.
Identify when the activity was first detected.
Identify the number of systems, records and users impacted.
Identify the network location of the observed activity.
Identify point of contact information for additional follow-up.

There are two main types of ransomware: locker and crypto ransomware, each with many variants (click here for more)...
Locker Ransomware: It works by preventing system administrators from reaching their systems by denying access to computing resources, and then demanding a ransom to regain access. Imagine a cybercriminal changing the administrator and root passwords in your corporate servers or cloud servers.
Crypto Ransomware: it works by encrypting the organization’s data, taking it hostage until the victim pays the ransom and obtains the decryption key from the attacker; otherwise, data is destroyed. Crypto ransomware is the most dominant threat and the focus of this article.
Island hopping, also called leapfrogging or pivoting, is a cybersecurity exploit in which an attacker gains access to an intended target by initially exploiting the employees and supply chain partners who have access to the target's network.
In this type of lateral attack, the threat actor exploits a weakness downstream from the actual target and uses it as a launching point to reach the intended target. The term island hopping is inspired by a military strategy used in the Pacific theater during World War II.
Generally, island hopping attackers pick employees, customers and smaller companies that work with the target organization, hoping that their cyberdefense will be weaker than the ultimate target. Island hopping attacks often begin through phishing exploits in which the attacker disguises themselves as a reputable entity in an email or other communication channel.

How do you write a Warning/Alert email about Ransomware to your Users? by one2254 on Apr 8, 2017 - Spiceworks
Dear End User,
Ransomware is a type of encrypting malware that encrypts important company files and holds them for ransom. Ransoms typically range from hundreds to thousands of dollars. Cybercriminals made over $1billion dollars last year from businesses attacked by ransomware and since these cybercriminals have learned to monetize attacks; their frequency and severity of attacks will continue to grow exponentially.
You should be aware that most ransomware attacks come in the form of an email attachment and you should exercise extreme caution when opening email attachments. Never open an attachment in an email you were not expecting to receive or that you do not recognize the sender. You should use the same caution when presented with URL's that you do not recognize or came from an unknown sender.
With today's advanced ransomware techniques you only have to visit a website to become infected with ransomware. Let me make that clear. You DO NOT have to click anything on the website to infect the company with data encrypting ransomware.
In 2017 alone:
Ransomware emails spiked 6,000%
40% of all spam email had ransomware
59% of infections came from email
92% of surveyed IT firms reported attacks on their clients
These numbers are scary but important for you to know. As an employee of (company ABC) you are our first line of defense against ransomware. Please follow the best practices as outlined in this email to ensure you do your part to keep ransomware off the company network. Failure to do so could result in significant downtime and monetary cost to (company ABC) and we all need to be vigilant in stopping these attacks.
If you have further questions about ransomware and how you can help prevent it from infecting (company ABC)'s network; please reach out to email@example.com or call the help desk at 1-555-555-5555.
