The Darkside Ransomware Group Is the Dangerous Poster Child for Today’s Ransomware-as-a-Service

April 29, 2021By TecAdmin0 comment

Looking beyond the “older” RaaS threat groups like Ryuk, DoppelPaymer, and Revil, today’s modern ransomware-as-a-service operator is far more business-like and specific in execution.

This now nearly 5-year old cyberthreat model empowers just about anyone wanting to be a would-be cyber-thug to jump in and use some very powerful and sophisticated tools to accomplish what only those with extensive development backgrounds could achieve. Most news stories focus on the more “successful” ransomware families, but a new article from cybersecurity vendor Avast showcases Darkside (a spinoff of Revil from back in 2020) – and it’s worth a read.

The newest trend in ransomware attacks is specificity; industry verticals, business sizes, victim titles and roles, social engineering themes and TTPs – and Darkside as them all.

According to Avast, Darkside is a great representation of the modern ransomware threat group:

They refine their victim target list, looking for the greatest ability to pay large ransoms
They do a ton of diligence on who to target and customize delivery for each attack
Their approach to operations is far more corporate-like than a bunch of developers that built some affiliate-friendly ransomware and posted it to the dark web

The fact that a cybercriminal organization like this exists is troubling; the more organized the bad guys get, the more likely their chances of successfully attacking your organization. And with the added “as a service” factor, this concern should be multiplied ten-fold.

Remember, one of the most effective ways to thwart ransomware attacks using phishing as the initial attack vector is through Security Awareness Training which empowers users to identify suspicious email content before interacting with it, stopping the attack in its tracks.

Currently Popular Social Engineering Tactics

April 28, 2021By TecAdmin0 comment

Criminals are exploiting new technology to launch updated versions of old attacks, according to Derek Slater at CSO. George Gerchow, CSO at Sumo Logic, told Slater that threat actors are sending spear phishing emails that impersonate real employees within the organization.

“It’s not easy to defend what you can’t see, and you are only as strong as the weakest link,” said Gerchow. “For example, there have been a plethora of targeted emails coming in that look like they are from your trusted partners but are in fact bad actors posing as employees you may know within your network.”

Gerchow added that attackers are putting more effort into making their social engineering techniques extremely convincing.

“Now we see these long, sophisticated attempts to build trust or relationships with some of our outbound-facing teams whose entire job is to help,” Gerchow said. “The bad actors have even posed as suppliers using our product with free accounts and have gone through use cases and scenarios to engage expertise within our company.”

Oz Alashe, CEO of CybSafe, told CSO that some attackers exploited the pandemic by sending malicious versions of remote work and collaboration tools.

“The threat actors send over a Visual Studio Project containing malicious code,” Alashe said. “The user self-runs the program, and their device is infected pretty quickly. This attack essentially exploits the desire or need to assist or help others with passion projects”

Privacy expert Rebecca Herold told CSO that text message scams are also growing more widespread.

“We are becoming a society where a large portion of the population prefer communicating via text messages as opposed to phone,” Herold said. “People are now extremely used to communicating very confidential types of information via text.”

Gerchow concluded that training is an essential component of a comprehensive security posture.

“Training, awareness, self-reporting, and transparency will be the only way to scale security around these attacks,” Gerchow said. “Security needs to be approachable and of course, log everything.”

New-school security awareness training can create a culture of security within your organization and enable your employees to thwart social engineering attacks.

The Digital Workplace is a Cybersecurity Disaster!

April 19, 2021By TecAdmin0 comment

New data reviewing how the 2020 shift to a remote workforce impacted organizational security shows all too well that since the pandemic onset, cybersecurity has become critically worse.

We all know IT’s focus during the pandemic was to primarily get the business running remotely. Other initiatives – such as compliance and cybersecurity – fell to the back burner. I wrote mid-pandemic about how the remote workforce was anything but secure.

Now new data from security vendor Mimecast in their report The Year Of Social Distancing: Security Challenges of the New Digital Workspace makes it clear that since the beginning of the pandemic and the shift to a remote workforce, the organization’s cybersecurity stance took a dive:

There was a 48% increase in the volume of threats
60% of U.S. workers opened suspicious emails
The number of unsafe clicks per user rose 300%
There was a 60% increase in personal use of a corporate device

With attacks up and the user’s sense of cybersecurity at an all-time low, it’s imperative that organization’s realize the likely current of their own workforce and look for ways to improve their defenses. Three of the four stats above have everything to do with the user’s lack of cybersecurity-mindedness and a lack of organizational security culture.

It’s only through Security Awareness Training that users can begin to weave cyber-vigilance into their daily work and personal activities that have practical implications like not opening suspicious emails or clicking unsafe links that result in putting the organization at risk.

[HEADS UP] DocuSign Issues Alert of Malicious New Hacking Tool

April 15, 2021By TecAdmin0 comment

Earlier this week, DocuSign issued an alert that notified users of a new hacking tool. This tool is imitating DocuSign so then the bad guys can drop malware into victims’ systems.

The tool is named “EtterSilent”, and it created Microsoft Office documents that contain malicious macros to exploit a known Microsoft Office vulnerability. The alert states, “This activity is from malicious third-party sources and is not coming from the DocuSign platform.”

Check out DocuSign’s helpful guide on their website of helpful indicators of compromise here. If your users use DocuSign, it is essential to alert your users of this potential threat so then your organization can avoid becoming the next victim.

Frequent phishing tests and continual new-school security awareness training can ensure your users are prepared and equipped to respond in situations similar to this. User education is essential for your users to spot and report and suspicious activity.

3 Ways To Protect Your Identity Online

April 14, 2021By TecAdmin0 comment

Within security awareness training programs, cybersecurity experts promote various tactics and best practices to implement within personal and work environments to protect your identities online and reduce the risk of theft or privacy loss. While these concepts seem like a broken record to some people, here are 3 best practices that can significantly reduce the opportunity for a cyber criminal to steal your data:

Stop Oversharing
When creating new online accounts with a financial institution, or other accounts that contain a lot of sensitive information, there will come the point in the process after creating the username and password, where you will be asked to enter responses to various security questions. Examples of these questions include “what is your mother’s maiden name?”, “what was the make and model of your first car?” or “what is the name of your high school mascot?” While this feature is designed so that only you know the answers, many cyber criminals can find the responses to these questions through social media or other public records and by using Open Source Intelligence (OSINT). Most of the time, it comes from reviewing user’s social media accounts.

When searching on various social media platforms and with a bit of ingenuity, it is easy to search public profiles and find out where you grew up, and what schools they have attended. Another quick Google search for the high school and mascot, and they have an answer to one of the security questions. Finding the make of a car model can be discovered after searching through comments, or if you post about getting a new car.

While this seems far-fetched and a little unusual, it’s easier than you think to overshare information online, and believe it’s only being shared with your friends. With more and more social media apps for short videos, pictures and posts, you could be share more information than you realize.

One best practice is to review and lock down the privacy settings of the app. Limit it to just the people who follow you and make sure you know all of them. Make sure to review that follower list several times a year to make sure you still know everyone. Imagine that you are posting videos or images for the world to see. In that case, one recommendation is to make sure it does not contain anything about the location or other personal information, like license plates in the background or information about the area.
Google Yourself
Seriously. We are always searching for recipes, videos on do-it-yourself projects, etc. Given the oversharing that often takes place on social media, an additional method to protect your identity online is to discover your digital footprint by seeing what the internet knows about you. Start with your first and last name. Search by your street address, email address, your mobile phone number and review the results. Most likely, the information found online will not come as a surprise. It is important to consider that cyber criminals can also use this information in an attempt to gain trust and have the user click a link, open an attachment and be socially engineered to take any action you may not have otherwise taken.

Suppose information online is discovered that is something that is not to be shared or known. In that case, there are procedures that the hosting organizations must have to allow you to request that your information be removed. Sometimes it does take a few attempts for the request to occur, but the site does have to remove the data relating to you after you prove it is you.
Practice Good Password Hygiene
Oh no! Not passwords again!? Surprisingly, this is the most damaging to online identities. Too many victims learn too late that cyber criminals have access to their accounts because they used a password from another account in a data breach. As BJ Fogg, founder of the Stanford University Behavior Design Lab, states, “Three truths about human nature: we’re lazy, social and creatures of habit.” This analysis applies to people when it comes to passwords. Too lazy to create strong passwords, or it is just easier to remember one password or maybe a slight variation to it for each website to make it easier to remember.

It’s important to never reuse passwords on your social media accounts, financial institutions and any site that provides personally identifiable information (PII) to an organization. Suppose that organization suffers a data breach and usually involves customer data. In that case, the cyber criminals can sell that information online for money or use it to target people with emails that entice the user to click the link and open the front door for cyber criminals.

One idea is to make passwords easier to keep track of inside a vault, which provides many benefits. The password vault allows you to store their strong and unique passwords securely. In the unfortunate event that an organization is breached, you only needs to change the password for that one account and not all the other accounts where they used the same password. This action alone can take a significant amount of time if they have to log in and change the various sites’ passwords.

Remember those security questions earlier? Well, the password vault can also store those responses. Instead of answering those questions truthfully, you can provide a random response to any of the security questions and keep the answer in the vault for that account. Instead of responding with “Toyota Camry” as your first car, the response could be “lightbulb.” No one will guess a completely random word, but as it is stored in the password vault, it is secure. It will reduce the risk of the account being compromised because the cyber criminal wastes time finding information that will be wrong for the security questions.

One other important note about password vaults: you users have to remember the primary password to get into the vault. The various commercial password vaults do not store or know the password for your user’s vault. This concept is known as zero-knowledge storage. The developer organization stores the password vault database file, but you own the decryption key, so it is important not to forget the password.

Keeping a password vault with strong and unique passwords is one of the best ways to protect your accounts online, but also knowing what information is out there about you is essential. Events and other information about people’s lives these days are posted for the world to see. However, one must be aware of what is shared and strive to ensure that the information cannot be used against them.

We recommend sharing these tips with your users to help them make smarter security decisions every day!

2021 Phishing Trends Face Alarming Predictions and Will Likely Include Automated Attacks

April 13, 2021By TecAdmin0 comment

Researchers at INKY warn that targeted phishing attacks will continue throughout 2020, as some employees return to the office and others continue working from home. They predict that spear phishing attacks will begin to grow more automated, allowing more attackers to launch these attacks.

The researchers expect to see the following five trends for the rest of the year:

“Additional government impersonators will be trying to gather personal information or illicit money through sophisticated phishing scams.
“Cloud breaches will be on the rise as companies continue to offer remote working options to their employees.
“Targeted data theft will climb due to the fact that thousands of businesses have not done enough to properly secure their sensitive information from hackers and cybercriminals.
“Ransomware attacks could escalate as they did in 2020, a year that saw $29.1 million in damages. Using email phishing campaigns, cybercriminals have compromised email accounts using precursor malware, which enables the hacker to then use a victim’s email account to further spread the infection.
“Spear phishing campaigns – which impersonate a CEO, vendor, or other known person – will likely see more sophistication and even automation. This will drive the number of incidents, the complexity, and the likelihood that an employee will fall for this costly phishing threat.”

The researchers conclude that organizations shouldn’t grow complacent as employees begin returning to the office.

“Much like health officials are urging us not to let our guard down for the pandemic this year, it’s also clear that we must be diligent in our efforts to protect our businesses from the cybercriminals’ phishing scams,” INKY says. “Nothing could be sadder than to see your organization through a pandemic, only to have it brought down by a sophisticated phishing event.”

New-school security awareness training with simulated phishing tests can familiarize your employees with these types of attacks so they can thwart them in the real world.

INKY has the story.

Australian Organizations Increase Cyber Security Spend to Nearly A$5B in 2021

April 12, 2021By TecAdmin0 comment

The rise in cyberattacks in Australia is seeing its natural result – organisations realizing the need to put more budget focused on cybersecurity, with the largest portion going towards services.

I make sure to represent Australia here in the blog, as they, too, are experiencing the same rise in cyberattacks as the rest of the world. Australia has seen a massive 75% increase in phishing attacks last year alone, earning them a spot at the cybersecurity table.

According to Gartner, Australian organisations are planning on spending A$4.93B on cybersecurity and risk management solutions. Cloud Security, Identity and Access Management, and Infrastructure Protection top the list of cybersecurity segments that are given the highest budget focus.

Every segment but one – “Other Information Security Software” – saw a rise in the amount of dollars to be spent. The largest segment, representing 65% of the spend, is “Security Services, which Gartner did not expand upon.

Sadly, what’s missing from the list above is Security Awareness Training, which has been proven to be very effective in significantly reducing the risk of cyberattack via phishing – shown to involved in more than 90% of all cyberattacks. The data has shown that organizations who have instituted this kind of training achieve a 87.5% reduction in the phishing threat surface – in layman’s terms, users are 87.5% less likely to click on a phishing email.

This level of efficacy demands a line item on every organisation’s cybersecurity budget. Let’s hope at very least it’s included as part of “Security Services”.

Office 365 Phishing Kits Are Being Used in a New Attack Targeting Execs and Finance

April 8, 2021By TecAdmin0 comment

A new highly-targeted phishing campaign is seeking to compromise the online credentials of those with influence within an organization using an Office 365-themed update attack.

The bad guys used to try to con anyone with the organization they could and then work to swim “upstream” to compromise someone in IT, an executive, etc. These days, the bad guys are dialed into using online tools like LinkedIn to identify their targets and work by using social engineering tactics to convince their victims into giving up valuable credentials.

In a new attack spotted by security vendor Area 1 targets financial departments, C-suite executives and executive assistants within the financial services, insurance and retail industries.

Using an Office 365 service update phishing email as the initial attack vector, prospective victims are encouraged to open the attachment to read about an important update. The attachment can be a PDF, HTML or HTM file.

Figure2-3

Source: Area 1

A JavaScript “unescape” command is used to obfuscate the HTML that loads a phishing kit-based Office 365 credential harvesting site. The phishing kit even includes a very realistic touch of popping up an updated privacy policy before allowing the user to continue.

Figure5-3

Source: Area 1

All this works to lower the victim’s defenses, establish credibility, and increase the chance of attack success.

Teaching users via Security Awareness Training to watch out for abnormal communications (such as “Microsoft” using an attachment to convey update details) can stop attacks like these in their tracks, no matter how convincing their phishing kit is.

The Growing WeTransfer Phishing Campaign Can Put Your Users at Risk

April 7, 2021By TecAdmin0 comment

Researchers at Avanan have observed a phishing campaign that’s impersonating the WeTransfer file-sharing app in an attempt to steal users’ credentials. The email’s subject line states, “You received some important files via WeTransfer!” The body of the email informs recipients that they’ve received three files through the service, with a link to “Get your files.”

The text of the email was worded awkwardly, however, which could tip some users off:

“Dear Sir/Madam,

Attached is our order catalogue and PO-209-2021 And Terms & Condition, please check if you can provide us with those, and quote.

Look forward to have a cooperation with you ,thanks.”

The email also states “Will be deleted by April 5, 2021” to instill a sense of urgency and motivate users to click the link. The link leads to a convincingly spoofed version of WeTransfer’s website, with a popup presenting a button for the user to download their new files. The names of the files are “List of Items.pdf,” “Drawings and Specifications.zip,” and “Company Profile.mp4.”

If the user clicks the button, they’ll be taken to a login page to verify their WeTransfer credentials. When they try to log in, their credentials will be sent to the attacker. The victim will be told that a technical error occurred, and the site will request that they re-enter their password.

“Hackers will do anything to get in your inbox,” Avanan concludes. “Posing as a trusted file-sharing source, with an email you may often get, tends to be a good way to do that.”

While this phishing attack isn’t highly sophisticated, some people will still probably fall for it. Avanan notes that the phishing site’s URL clearly didn’t resemble WeTransfer’s legitimate URL, so observant users could have recognized the scam. New-school security awareness training can teach your employees how to spot the signs of phishing attacks.

[HEADS UP] Millions of Facebook Users’ Personal Information Has Been Leaked Online

April 6, 2021By TecAdmin0 comment

A hacking forum recently published over 553 million personal data of Facebook users. The type of exposed data ranged from phone numbers, Facebook ID’s, full names, locations, birthdates, bios, and in some cases – email addresses.

Alan Gal, CTO of Hudson Rock, was the person who first discovered the data leak over the weekend. “A database of that size containing the private information such as phone numbers of a lot of Facebook’s users would certainly lead to bad actors taking advantage of the data to perform social engineering attacks [or] hacking attempts,” Gal said in a statement.

Unfortunately, this is not the first time personal information has been leaked of Facebook users. In 2019, the Facebook vulnerability exposed millions of users’ phone numbers that was pulled from Facebook’s servers that were in violation of the terms of service.

There’s not much Facebook can do because users are trusting Facebook with their data, and it’s up to Facebook to treat users’ data with care and sensitivity. Facebook should, however, notify users if there is a potential breach.

These types of data breaches should have a takeaway that your organization needs to be vigilant of any suspicious activity at all times. New-school security awareness training is of the utmost importance for make sure your users know how to respond to a potential scam.
