Scale, details of massive Kaseya ransomware attack emerge
Cybersecurity teams worked feverishly Sunday to stem the impact of the single biggest global ransomware attack on record, with some details emerging about how the Russia-linked gang responsible breached the company whose software was the conduit.
An affiliate of the notorious REvil gang, best known for extorting $11 million from the meat-processor JBS after a Memorial Day attack, infected thousands of victims in at least 17 countries on Friday, largely through firms that remotely manage IT infrastructure for multiple customers, cybersecurity researchers said.
REvil was demanding ransoms of up to $5 million, the researchers said. But late Sunday it offered in a posting on its dark web site a universal decryptor software key that would unscramble all affected machines in exchange for $70 million in cryptocurrency.
Earlier, the FBI said in a statement that while it was investigating the attack its scale “may make it so that we are unable to respond to each victim individually.” Deputy National Security Advisor Anne Neuberger later issued a statement saying President Joe Biden had “directed the full resources of the government to investigate this incident” and urged all who believed they were compromised to alert the FBI.
Biden suggested Saturday the U.S. would respond if it was determined that the Kremlin is at all involved.
Less than a month ago, Biden pressed Russian President Vladimir Putin to stop giving safe haven to REvil and other ransomware gangs whose unrelenting extortionary attacks the U.S. deems a national security threat.
A broad array of businesses and public agencies were hit by the latest attack, apparently on all continents, including in financial services, travel and leisure and the public sector — though few large companies, the cybersecurity firm Sophos reported. Ransomware criminals infiltrate networks and sow malware that cripples them by scrambling all their data. Victims get a decoder key when they pay up.
The Swedish grocery chain Coop said most of its 800 stores would be closed for a second day Sunday because their cash register software supplier was crippled. A Swedish pharmacy chain, gas station chain, the state railway and public broadcaster SVT were also hit.
In Germany, an unnamed IT services company told authorities several thousand of its customers were compromised, the news agency dpa reported. Also among reported victims were two big Dutch IT services companies — VelzArt and Hoppenbrouwer Techniek. Most ransomware victims don’t publicly report attacks or disclose if they’ve paid ransoms.
CEO Fred Voccola of the breached software company, Kaseya, estimated the victim number in the low thousands, mostly small businesses like “dental practices, architecture firms, plastic surgery centers, libraries, things like that.”
Voccola said in an interview that only between 50-60 of the company’s 37,000 customers were compromised. But 70% were managed service providers who use the company’s hacked VSA software to manage multiple customers. It automates the installation of software and security updates and manages backups and other vital tasks.
Experts say it was no coincidence that REvil launched the attack at the start of the Fourth of July holiday weekend, knowing U.S. offices would be lightly staffed. Many victims may not learn of it until they are back at work on Monday. Most end users of managed service providers “have no idea” whose software keep their networks humming, said Voccola,
Kaseya said it sent a detection tool to nearly 900 customers on Saturday night.
The REvil offer to offer blanket decryption for all victims of the Kaseya attack in exchange for $70 million suggested its inability to cope with the sheer quantity of infected networks, said Allan Liska, an analyst with the cybersecurity firm Recorded Future. Although analysts reported seeing demands of $5 million and $500,000 for bigger targets, it was apparently demanding $45,000 for most.
“This attack is a lot bigger than they expected and it is getting a lot of attention. It is in REvil’s interest to end it quickly,” said Liska. “This is a nightmare to manage.”
Analyst Brett Callow of Emsisoft said he suspects REvil is hoping insurers might crunch the numbers and determine the $70 million will be cheaper for them than extended downtime.
Sophisticated ransomware gangs on REvil’s level usually examine a victim’s financial records — and insurance policies if they can find them — from files they steal before activating the ransomware. The criminals then threaten to dump the stolen data online unless paid. In this attack, that appears not to have happened.
Dutch researchers said they alerted Miami-based Kaseya to the breach and said the criminals used a “zero day,” the industry term for a previous unknown security hole in software. Voccola would not confirm that or offer details of the breach — except to say that it was not phishing.
“The level of sophistication here was extraordinary,” he said.
When the cybersecurity firm Mandiant finishes its investigation, Voccola said he is confident it will show that the criminals didn’t just violate Kaseya code in breaking into his network but also exploited vulnerabilities in third-party software.
It was not the first ransomware attack to leverage managed services providers. In 2019, criminals hobbled the networks of 22 Texas municipalities through one. That same year, 400 U.S. dental practices were crippled in a separate attack.
One of the Dutch vulnerability researchers, Victor Gevers, said his team is worried about products like Kaseya’s VSA because of the total control of vast computing resources they can offer. “More and more of the products that are used to keep networks safe and secure are showing structural weaknesses,” he wrote in a blog Sunday.
The cybersecurity firm ESET identified victims in least 17 countries, including the United Kingdom, South Africa, Canada, Argentina, Mexico, Indonesia, New Zealand and Kenya.
Kaseya says the attack only affected “on-premise” customers, organizations running their own data centers, as opposed to its cloud-based services that run software for customers. It also shut down those servers as a precaution, however.
Kaseya, which called on customers Friday to shut down their VSA servers immediately, said Sunday it hoped to have a patch in the next few days.
Active since April 2019, REvil provides ransomware-as-a-service, meaning it develops the network-paralyzing software and leases it to so-called affiliates who infect targets and earn the lion’s share of ransoms. U.S. officials say the most potent ransomware gangs are based in Russia and allied states and operate with Kremlin tolerance and sometimes collude with Russian security services.
Cybersecurity expert Dmitri Alperovitch of the Silverado Policy Accelerator think tank said that while he does not believe the Kaseya attack is Kremlin-directed, it shows that Putin “has not yet moved” on shutting down cybercriminals.

When it comes to ensuring the highest levels of cybersecurity for any establishment, password management in network security is one of the most paramount factors in guaranteeing security. As one of the essential cybersecurity measures, password management is a critical element for any online activity, whether for software or hardware. Everything is protected with a password.
What is Password Manager and How does it Work?
To those not familiar with the concept, password management’s significance exceeds the creation of a strong password to protect your data or account. It is a cybersecurity system. A system that manages any saved login credentials, all while guaranteeing a safeguarded relocation of data from one device to another. When coming up with a valid password, a few factors must be taken into account, such as the potential of being exposed to high risks and identity theft.
For any establishment, the correct password manager helps to monitor any activity and amounts of logins for servers people work on. As a software application, it is developed for storing and managing online credentials. With the increased available platforms and programs requiring safety credentials, the risk of losing or forgetting a password has never been higher. User password management, such as Google password manager, helps users with a handful of passwords for essential web applications.
By providing the needed digital space to generate and store any, and all passwords in one location, password management in network security keeps any data safe and secure in various ways, including biometrics data.
Why Use Password Manager?
Through the encryption of users’ logins, a reliable password manager protects your credentials and cannot be accessed until the master password is submitted. In this case, no password is stored on the device itself or even on the manager’s servers. While some might think that storing all of your important passwords in one place might be hazardous, the truth is, password managers are the safest bet to safeguard all your passwords, as the chances of a password manager being breached are extremely low and almost very unlikely to happen.
Without getting into all the technical terms as to why password managers are the safest option, these applications can be perceived as the lesser evil. While users will still need to create one master password – preferably to be long and a bit complicated – it will guarantee the protection of any login credential for any account or credit card information.
The ideal password managers to download are backed by two-factor authenticators, where users are asked for a one-time code alongside the password whenever a new login into a new device takes place.
Password Management Best Practices in Network Security
In terms of obtaining the highest level of protection for network security, few practices are applicable to almost anyone to ensure the highest level of user password management.
1. Training
Training the team and raising awareness of potential password threats is one of the most important things to consider. Team members working on network security have to understand the risk of cybersecurity and the importance of implementing the right measure to protect and secure any account credential.
2. Enforcement of Reliable and Strong Passwords
Enforcing the creation of strong passwords and establishing they follow the best practices for network security to protect the network and its data while respecting the integrity, confidentiality, and accessibility of the network’s computer systems.
This includes performing a thorough network audit, deploying network and security devices, disabling file sharing features, updating antivirus and anti-malware software, securing all routers, using a private IP address, and finally establishing a network security maintenance system.
3. Multi-factor Authentication
Endorsing your password management with two-factor authentication is like adding another solid layer of protection to your accounts and their passwords. Multi-factor authentication ensures that only people responsible for the network have access to its sensitive data.

We are all well aware of the troubles opening a fishy link can lead us to. Luring users to click on a given link has been of one the well-known techniques to get access to the device, install virus and malware or even go as far as creating a full ransomware attack. To protect your computer and private information, there are multiple techniques to check links without opening them. What is important though is never to open the link if it is suspicious.
Visually Inspect the Link
When you are not dealing with a shortened URL, the best way to go thoroughly through the link to see if there is any spelling mistake. Attackers usually tend to change a minimum number of letters so that you are unable to tell the difference. For instance, things like www.goagle.com instead of www.google.com should catch your attention with the second ‘o’ of Google replaced with an ‘a’.
Verify that Links in an Email Come from a Credible Source
Emails are the best sources for phishing attacks. These kinds of attacks are used to steal some sensitive information such as passwords and credit card information. The best way to avoid these kinds of attacks is to authenticate the sender. For that purpose, do not only check the name of the sender, you need to double-check the email the sender is using. In general, attackers use credible sender names with emails which do not correspond to the promoted identity. Next time you get an email from your bank like “XBank”, check that the sender email is person@Xbank.com rather than person@anyothermailclient.com.
Use Link Checker or Link Scanner
Many websites actually provide link checking or link scanning features. This is a very neat technique to simple check the link before clicking on it.
VirusTotal
www.virustotal.com is an excellent website for this task. This online tool practically does the job of an anti-virus. When you go to the website, you have the possibility to analyze files and URL for malware or any other security breach. Once you submit your file or enter the URL, the website will use different tools and software, then provide you with a detailed output from each of these tools. If you are unsure if a given software is credible enough, you can compare it to the output of other platforms on a single website.
Use a Short URL Expander
Sometimes attackers try to shorten URLs to hide any malicious intention. Analyzing shortened URL is not straightforward. To overcome this problem, copy the provided URL without opening it and use specific websites that actually expand the provided URLs. Then, you can analyze the original URL for possible security breaches. Many websites are there to do this task. Just search for “short URL expander” on your search engine and use the top provided websites.
Upgrade your Anti-Virus with Internet Security Features
Anti-virus software is commonly used to protect personal computers from viruses and other malware. While these are available for free, you can easily upgrade them to include internet security features for a small monthly fee. This will bring major improvement to your internet browsing experience including custom-made safe browsing tools.
Use Google Transparency Report
Google provide a nice tool to check for the safety of websites. To do so, visit https://transparencyreport.google.com and enter the URL in question. The Google source will then provide you with a safety report of that website.
Simply Hover Over the Link
The nicest solution is kept to the end. When you hover over a link in your email client or web browser, a small square appears including all the information related to the chosen URL. These details can be used to give a preliminary indication whether to trust the source.
Final Thoughts
Suspicious links are everywhere! To make sure they don’t catch you by surprise, follow the highlighted and you’ll be safe to go.

Cybersecurity and artificial intelligence (AI) are two very trending topics at the moment. AI has been the pivotal elements modifying business strategies, improving decision-making processes, and triggering automation in every industry in the world. The latest sentience debate is a clear indicator on serious and advanced AI is becoming nowadays. Cybersecurity is the other important element of today’s technological world. With an increasing reliance on data and the move to online services that require an individual’s biometrics, security essential in preventing data thefts and associated cybercrimes. AI has undeniably improved cybersecurity practices by allowing a real-time analysis of internet traffic to discover possible threats at the earliest and take defensive actions. This important learning process hides however several disadvantages of AI in cybersecurity.
What Are the Downsides to AI in Cybersecurity?
The touted advantages of AI in cybersecurity are real and very useful. However, the increasing adoption of AI solutions for security is actually causing problems at different levels.
Hackers Use AI as Well
When it comes to maturity in technology, hackers are the best at it. These individuals sitting behind computer screens logging data and doing advanced analytics to identify any loophole or vulnerability they can use to their benefits. The use of AI as far as cybersecurity is concerned is a double-edged sword. It is actually a race of who can develop a better algorithm that caters better to the data which is circulating online. In this sense, the use of AI is a big threat to security.
Another issue is that while a company is analyzing and learning from data to discover threats, a hacker is concurrently analyzing the company’s cyber-defense mechanisms and policies to find “open doors’ that will take it into the system to complete the intended attack.
Data Confidentiality
AI algorithms are associated with the analysis with large volumes of data, a key requirement for the developed algorithms to produce accurate outputs. The data a company deals with contains normal traffic related to daily transactions and activities, but also sensitive information related to the clients including their biometrics and personal information. What happens to our data when it goes to the AI-agent though is another thing. Protecting the data is key when AI is used for cybersecurity reasons. The secrecy of the clients’ data should not be compromised for any reason.
Increasing Need for Data
The field of cybersecurity is constantly evolving with ingenious attacks and threats emerging every now and then. Browser-in-the-browser attacks and increasingly advanced ransomware attacks have been notable examples in 2022. In order to discover attacks at a later stage, the AI algorithm needs to have data to do the proper training. The increasingly dynamic environment with threats emerging and evolving will lead to a surge in the required volumes of data, which can potentially not be readily available to have a fast response to the attack itself. Whether it is the ability of AI to keep track of the exponential growth in data or the availability of data for the AI-algorithm to produce results is a big disadvantage of this approach for cybersecurity
Will Cybersecurity be Replaced by AI?
With the drive towards more and more automation, it is questionable whether this can be applied as well for cybersecurity practices. AI can certainly assist in processing and learning from data and produce insights. However, the real decision maker in such as sensitive area where no errors can be tolerated is the cybersecurity expert himself. The only way for AI to replace cybersecurity is when it becomes sentient or developed enough to think and act like humans do. There is still a long way for that to concretize.
Explainable or interpretable AI is a key intermediate step in reaching this target. First, we need to understand how AI produces results. Proper cybersecurity practices require a reduction in bias while optimizing the performance of the algorithm.
How Will AI Affect Cybersecurity Jobs?
The adoption of AI will certainly cause major shifts in the cybersecurity job market as in the case in other industries, but probably at a smaller scale. The level of skill and experience needed to thwart cyberattacks will safeguard the need for security experts to provide the final decision regarding suspicious data patterns.
On the other hand, the incorporation of AI will call for new skilled workers that can manage and optimize the performance of the algorithms. Another alternative would be for existing workforce to be upskilled and retrained to handle the new analysis tools.
Summary
As data is becoming the basic unit for decision making, AI has invaded all industries and businesses, including cybersecurity. Companies are starting to incorporate learning algorithms to their offered services in order to have a more intelligent management of the different security threats. However, the role of AI in cybersecurity should be considered with enough judgment. The addition of AI would increase the complexity in the data management process, notably in terms of data privacy and the continuous need for more data.
