The ways that people communicate at work has evolved over the years, with online messaging services and email becoming more important. However, the office phone has remained a staple of office communication for decades. Recent advancements have changed what that phone system looks like. Voice over Internet Protocol (VoIP) phone systems have replaced traditional landlines in many offices, allowing workers to make phone calls over an internet connection. With advantages like lower costs, portability, and accessibility, VoIP systems have become more popular for small businesses who have transitioned to working at home.
Hackers have taken notice of that increase in popularity. Over the summer, a hacking campaign has compromised the VoIP systems of over 1000 companies across the globe. Their primary goal was using the system to dial premium numbers that they owned. On top of that, criminals were able to eavesdrop on private calls and use the business network to mine cryptocurrency. While researchers have identified the vulnerability that hackers used to exploit the system, law enforcement has not yet been able to identify the group or groups responsible. While the benefits of VoIP are great, there is a real risk in using these systems to communicate
So what do you need to do to keep your business safe? First, identify what brand of VoIP system your company is using. These attacks were only possible on Sangoma and Asterisk systems. If you have one of these systems, we highly recommend that you identify whether the flaw has been patched, and patch it if it has not. If you have a VoIP phone system and are concerned about your business’s risk, contact us at firstname.lastname@example.org to learn about how a managed services provider can protect your business from exploits like these.
When people think of spam emails, it’s usually phishing that comes to mind. These are the emails that make up your junk folder: a truly frightening combination of poor grammar, bad spelling, and vulgarity that makes you question how anyone can fall for a phishing attack. Spear-phishing has become the new way to create a spam email campaign. By targeting specific demographics and crafting believable ‘lure’ emails, cybercriminals can entice people to click untrustworthy links in their emails. In recent years, the group TA542 has been one of the most prolific criminal entities to use spear-phishing as their primary form of cybercrime, sending almost one million fraudulent messages a day.
Their latest attack was a campaign targeting supporters of the Democratic party in the United States. Their lure emails mimic the language on emails sent from Democratic activist groups like ActBlue, leading people to believe that the sender is trustworthy. Once they click on the link in the email, they unwittingly download TA524’s signature malware, a program called Emotet. This does anything from scanning your computer for personal information to downloading your banking credentials. TA542’s combination of realistic lure emails and sophisticated malware makes them a particularly dangerous group of cybercriminals. However, there are still steps you can and should take to protect your data!
Traditional advice about how to avoid phishing scams is not to open links from people or companies that you aren’t familiar with. However, spear-phishing emails mimic those trusted senders. Some ways to stay safe in this new environment is only to open links or documents that you are expecting to receive. When you receive a link in an email that is unfamiliar or unexpected, go to the sender’s website and navigate to the desired page from there. As cybercriminals become more advanced, having outside tech support becomes increasingly important—if someone from your company falls prey to a spear-phishing attack, having secure data backups and a plan for how to mitigate the damage caused by the malware is crucial.

Work-from-home is the reality for so many of us during the coronavirus pandemic. Being out of the office has its challenges: interrupting kids, spotty internet, and endless miscommunications! However, online meetings have become the symbol of this new working environment, especially the virtual meeting app ‘Zoom’. Part of the app’s popularity was its security. Zoom increased its revenue over 300% during the pandemic, due in part to its security guarantees. That all changed when investigators discovered that the company had not been completely honest about their security protocols.
Zoom had always represented itself as having end-to-end encryption. This meant that no-one except meeting participants could access non-encrypted data on the meeting. It claimed to provide that encryption long as everyone accessed the call using their computers. Instead, users only had access to TLS, transport layer security. This meant that Zoom had access to unencrypted meeting data. The outrage prompted Zoom to release an updated version of their security that included true end-to-end encryption. So now that Zoom’s improved security has been released to the public, is it worth returning to the platform?
The good news is that now Zoom does seem to have full end-to-end encryption. The updated security option is available for everyone, a change from their initial plan to only offer it to paid users. This makes Zoom one of only a few videoconferencing platforms to offer the service. However, the option does still have its drawbacks. For free users, the feature requires two-factor authentication to enable. Each user has enable the feature, meaning a meeting host cannot enforce the feature. The option is only available in meetings with under 200 members, an 80% reduction in capacity.
In the end, Zoom’s updated security policy makes it a great option for smaller, secure meetings. Individuals and small business owners will love the combination of convenience and security that the free option provides without being inconvenienced by the member limit. However, the removal of features and need for manual authentication from every member makes Zoom’s end-to-end encryption impractical for most large meetings. Cybersecurity has only become more important in the past few months, so making sure your meetings are safe is crucial.

So what makes this code so dangerous? When downloaded, they create a ‘shell’ on the user’s computer. This ‘shell’ allows bad actors to connect remotely to the user’s device. This means that the bad actors had complete access to the information stored on the computer. They could even download more malware to the device so that removing the package did not remove their access. For this reason, NPM stated that any computer with these packages installed should be considered ‘fully compromised’.
If you downloaded these packages on your devices, you are at risk. You should take some steps to secure your information:
- Think about wiping your computer.
- Rotate any sensitive information from a different computer.
- Remove the package from your computer.
Finally, this is a situation where you should consider seeking outside help. If you want to keep the compromised device, an outside IT firm is a great resource to make sure that your information is secure. Contact us here if you think that this may have affected your computer. You can also call us at (703) 790-0400.
Sometimes it seems like it’s impossible to keep your business safe. Software is constantly improving. Cybercriminals are becoming more technologically savvy. The list of security to-do’s is growing ever longer. With all that happening, it can be hard to figure out where to start. One option is to hire someone to do the heavy lifting for you. However, taking some simple steps on your own can be a great first start.
The good news is that preventing the vast majority of cybercrime doesn’t require a lot of technical know-how, just some basic knowledge of how cybercrime happens. Most cybercriminals are not spending days writing code to get into your system. Instead, they try to trick you and your employees into opening the door for them. Phishing campaigns are a popular way of doing this: someone sends your employee an unexpected email asking them to click a link or open a file. The next thing you know, your system has been infected with malware and you have to write some very embarrassing emails to your clients explaining why their contact information has been stolen. Most successful cybercrime happens in a situation like this, where someone within the company lets malware in.
So how do you stop it? Have regular meetings with your employees about the importance of information security. Make sure they know the basics. Never open anything from an unfamiliar sender and never install software (or browser add-ons, or applications) unless they are company-approved. Also, don’t click on strange links or visit shady websites. It’s important to ground information security in the real world. While it can be hard to understand how opening a link could cost your company millions, it is a lot easier to get how that same link steals their personal data. That personal touch is a good way to make sure that facts stick. Finally, if you’re in a position of power at your company, take charge! Create complexity guidelines for employee passwords and consider putting a secure password manager on company computers.

There’s a big event this month that everyone’s looking forward to! It’s full of tricks and treats, spooks and scares, and some very reasonable prices on inflatable skeletons. No, not Halloween—it’s Amazon Prime Day! Every year, millions of people flock to the shopping giant to score great deals on everything from computers to couches to canned goods. That’s the treat, but many cybercriminals use the day’s excitement to make money instead of saving some. This year, phishing attacks are on the rise. Scammers created almost 350 fraudulent sites using Prime Day as their lure. Cybercriminals are using this technique called ‘piggy-backing’ more and more often.
This year’s phishing campaign features fraudulent emails and sites that seem legitimate at first glance. They are specifically designed to resemble authentic Amazon support sites. These sites might ask you to input credit card information for a ‘refund’ or offer extravagant prizes for completing a small survey. There are also often small irregularities on these pages: links will be broken or nonexistent to prevent users from navigating away, images will be blurry, spelling and grammar mistakes are common. These inconsistencies should act as a sign that the site is fraudulent, so leave the page if you notice them!
Ultimately, the best way to avoid fraudulent sites and phishing campaigns on Prime Day is to stay away from clicking links in emails that claim to direct you to Prime Day sales or to a specific Amazon page. Instead, navigate directly to Amazon from your preferred browser and enjoy the sales. If you find yourself on a suspicious site, look out for the red flags that we mentioned earlier. When in doubt, get right out!

The number of cybersecurity breaches, rise in online scams and cold-call phishing has increased since the start of the Covid-19 pandemic with crooks buying personal data on the Dark Web that allows them to target individuals. The Dark Web fraud marketplace is a lucrative place with stolen data being sold anywhere from $4 for passwords for platforms such as TikTok, to $10 for Netflix and $450 for login details to mortgage and banking accounts.
The most expensive pieces of data sold are those that hold information about an individual’s financial details, but all types of data can be found on the Dark Web, with social media and email being the most commonly found on sale.
If you are worried about your personal information and want the ability to monitor the dark web, email us at firstname.lastname@example.org.
As cyberthreats and attacks continue to increase, a recent report by Positive Technologies reveals an analysis that exposes why that is. The report shows the costs of many cybercrime services across the dark web are surprisingly cheap.
According to the report, the costs of cybercrime services can begin from as low as $40 to $4,500. This means that hackers can infiltrate a business’ email and steal sensitive information for under $50 dollars. Since the price of attacks start so low, cybercrime is not directed at only big business. Reports show that 71% of SMBs are not prepared for cybersecurity risks, and with how cheap it is to attack, preparations are necessary. The report encourages all SMBs to begin conducting detailed digital risk assessments to protect their businesses.
Larger businesses must also remain vigilant as they are also not in the clear. Since some cybercrime services are so inexpensive, hackers could purchase multiple attack services to target one larger enterprise from different angles. If you are an SMB and you don’t know where to start, OptfinITy can help.

A report released shows an extreme increase of ransomware attacks over the course of 2020. Ransomware attacks have been on the rise and getting more dangerous in recent years, with cyber criminals aiming to encrypt as much corporate networks as possible to extort bitcoin ransom from companies before returning their data. A single attack itself can result in cyber criminals making hundreds of thousands or even millions of dollars depending on the size of the establishment.
Not only has the number of ransomware attacks increased, but ransomware has continued evolving, and some of the most popular forms of ransomware last have disappeared and been released with new forms of ransomware that are more disruptive and damaging. At this rate, a company’s best bet of surviving attacks of ransomware is to be fully protected and prepared.
If you are worried that you or your company are not prepared to handle ransomware attacks, OptfinITy can help. Feel free to contact us at (703)790-0400 or email us at firstname.lastname@example.org for more information.
A new study has revealed that there are potentially more than 15 billion stolen account credentials circulating on criminal forums within the dark web according to researchers at the cyber security firm, Digital Shadows.
As one would imagine, the most expensive credentials for sale on the dark web were those for accounts with bank and financial service companies. The average listing for these was $74 dollars. The number of stolen credentials has risen by more than 300 per cent since 2018, due to a surge in data breaches. With an estimated 100,000 separate breaches taking place over the last two years, the amount of data available has increased exponentially.
