Does Remote Work Impact Security?

By -- 2021-03-30 in Blog

Remote work has become a way of life for so many of us. It makes a lot of things harder. Communication, focus, and task management have all become more difficult. One of the things hardest hit by remote work is our online security. An overall increase in teleworking makes it harder for companies and workers to maintain cybersecurity standard for several reasons. This means that cybercrime has been more effective during the pandemic. Staying safe despite these threats means that decision makers need to make changes to how telework functions at their companies.

Why is cybercrime so effective now? One reason is that the devices that cybercriminals target are more important than ever. It used to be that if a cybercriminal locked an employee out of their computer, they could get a replacement and report the problem easily. Now, that same computer could take days to fix, with critical work halted in the meantime. A second reason is the added complexity that comes from having employees out of the office. Losing the office firewall means more vulnerable employees. Employees don’t have a security team in their house reminding them to change their passcodes or not to click on strange emails. Finally, work-from-home puts stress on remote security teams. With workers operating from changing locations and at changing times, it’s harder to identify irregular behavior.

You can take control of your business’s cybersecurity with a few simple steps.

  1. Regularly remind your employees about your business’s security protocols and cybersecurity best practices.
  2. Keep personal and work devices separate. Opening personal email or going shopping on a work device exposes a business to increased attacks.
  3. Enable multi-factor authentication on your devices. This is an easy way to keep threat actors from accessing any secure account.

These steps are just the beginning. While individuals should do their best to keep their devices secure, they can’t do it alone. Maintaining security for your business is complex. As cyberattacks become harder to identify and prevent, businesses’ security needs increase.

Data Leakage Attacks are Here to Stay

By -- 2021-03-20 in Uncategorized

What does a cyberattack look like? There’s no specific technique, target, or goal to unite them.  They can be part of an anti-terrorism campaign, like the United States’ Stuxnet attack on Iranian nuclear refineries.  They can be motivated by financial gain, like the recent trend of ransomware attacks that demand payment in Bitcoin before unlocking the target’s data.

Some attacks are simply done for hacker clout, like the spade of DDoS attacks done in the 90s and early 00s.  As time goes on, new cyberattack strategies are emerging that may define the rest of the decade.

In 2020, observers noticed an uptick in attacks that focused on securing and/or releasing corporate data.  Attacks that resulted in a data ‘leakage” increased over the past year, and 2021 has continued that trend through January.  On the first day of the year, over nine thousand data leakages occurred, a larger single day number than any day from 2020.  With 2020 already representing a 93% increase in leakages over 2019, any continuation of the trend is threatening.  Without a strong response to this trend from the

What Does a Cyberattack Look Like?

Cyberattacks vary widely in technique, target, and goal. Some align with anti-terrorism campaigns, such as the United States’ Stuxnet attack on Iranian nuclear refineries. Others aim for financial gain, like ransomware attacks that demand Bitcoin payments to unlock a target’s data. Some hackers execute attacks purely for clout, exemplified by the wave of DDoS attacks in the 90s and early 00s. As time progresses, emerging cyberattack strategies could shape the rest of the decade.

The Rise of Data Leakage Attacks

In 2020, attackers ramped up efforts to secure or release corporate data. Data leakage incidents rose dramatically throughout the year, and 2021 continued this trend. On the first day of 2021, attackers caused over 9,000 data leakages, surpassing any single day from 2020. Since 2020 saw a 93% increase in leakages compared to 2019, this escalation poses a severe threat. Without decisive action from public and private sector organizations that handle sensitive consumer data, the trend will likely continue to grow at an alarming rate.

Steps to Minimize Risk
Organizations can take the following steps to reduce their risk of cyberattacks:

– Identify sensitive data and its storage locations.
– Periodically review and delete unnecessary sensitive data.
– Monitor user activity involving sensitive data and restrict non-essential access.

Responding to a Data Breach

When prevention fails and attackers breach data, timing becomes critical. Developing a strategy for security response teams before an attack ensures faster identification, effective containment, and a reduced scope of leakage.

public and private sector actors who work with confidential consumer data, it is likely to continue its astronomic growth.

So what are some of the steps that possible targets of these attacks can take to minimize their risk?

  • identify what sensitive data your company holds and where it is stored
  • periodically review whether the sensitive data your company holds can be deleted
  • monitor user activity as it relates to sensitive data and limit non-essential access

In the case that prevention fails, and your business is affected by a possible data leakage attack, time is essential.  Creating a strategy for security response teams prior to an attack is crucial to properly identifying the attack, quarantining the data, and limiting the scope of the leakage.  If you or your company are looking for assistance in creating that plan, reach out to us at info@optfinity.com.

VoIP: Risk and Reward

By -- 2021-03-10 in Blog

The Evolution of Workplace Communication
Workplace communication has changed significantly over the years. Online messaging services and email have become vital tools. However, the office phone has remained an essential part of communication for decades. Advancements in technology have transformed traditional phone systems, with Voice over Internet Protocol (VoIP) replacing landlines in many offices. VoIP systems enable phone calls over the internet and offer advantages such as lower costs, portability, and accessibility. These features make them especially appealing to small businesses transitioning to remote work.

Hackers Target VoIP Systems
The growing popularity of VoIP has attracted the attention of hackers. Over the summer, a cyberattack compromised VoIP systems in more than 1,000 companies worldwide. Hackers exploited the systems to dial premium numbers they owned, eavesdrop on private calls, and mine cryptocurrency using business networks. While researchers identified the vulnerability that enabled the attack, law enforcement has yet to determine the responsible parties. Despite the benefits of VoIP, the risks of these systems cannot be ignored.

Steps to Protect Your Business

  1. Identify Your VoIP System
    Determine the brand of VoIP system your company uses. The recent attacks targeted Sangoma and Asterisk systems.
  2. Ensure the System is Patched
    If your system is one of the affected brands, check whether the vulnerability has been patched. Apply the update immediately if it has not.
  3. Consult with Experts
    If you are concerned about your VoIP system’s security, contact us at info@optfinity.com. A managed services provider can help safeguard your business from exploits like these.

Confidentiality in the COVID-19 Era

By -- 2021-02-28 in Uncategorized

The Impact of Remote Work on Productivity and Mental Health

The coronavirus has dramatically changed how we work. With new methods of communication, emerging threats, and less time in the office, some businesses have discovered that remote work is boosting productivity. Many remote workers report higher levels of job satisfaction and improved mental health due to gaining more control over their workday.

However, not all work is equally suited to this new normal. Businesses that regularly process confidential information are struggling to adapt their in-office privacy standards for remote work.

The Privacy Risks of Home Printing

A recent study by Go Shred revealed alarming trends in remote work practices. Nearly two-thirds of home workers admitted to printing office documents on their home printers. While some of these materials were not sensitive, others confessed to printing documents containing confidential client and employee data, such as home addresses and personal medical information.

The issues don’t stop at the printer. Disposal methods for these documents are often inadequate. According to the survey, 24% of respondents who printed confidential information had not disposed of the materials at the time of the survey. Of the 76% who destroyed the documents, approximately 20% relied on home shredders and municipal trash removal—another significant privacy failure.

Why Convenience Can Compromise Privacy

Convenience often takes precedence in the home office, leading to risky practices. While understandable, this behavior significantly increases business liability and consumer risk. Remote workers need defined procedures to follow, along with clear consequences for non-compliance. Decision-makers must navigate COVID safety protocols and confidentiality best practices to create these guidelines.

The Path Forward: Balancing Safety and Security

To address these challenges, businesses must prioritize:

  • Worker safety: Ensuring employees feel secure and supported in their work environment.
  • Data privacy: Establishing clear procedures for handling sensitive information.
  • Ease of use: Designing solutions that are practical for remote workers.

Creating comprehensive guidelines is the only way to address confidentiality concerns effectively—at least until we’re back in the office.

Ransomware: Why You Shouldn’t Pay to Get Data Back

By -- 2020-12-28 in Blog

Ransomware attacks have been on the rise for years.  The software necessary for these attacks are more sophisticated, anonymous currencies like Bitcoin are more prevalent, and companies are collecting more data, creating a perfect storm for bad actors looking to make money off of security lapses.  These scams take several forms.  The group could lock workers out of their devices, delete important data and offer to restore it upon payment, or steal data and threaten to release it to the public.  When people are victims of this kind of scam, the hacker offers to delete the data if the victim pays the group.  Some companies take the offer–but the hacker rarely delivers on their end of the deal.

Nearly half of all ransomware attacks include the threat to publish stolen data.  This was not always the case.  Previously, companies with a secure backup of their data could restore their data and ignore the hacker’s threats.  The threat of releasing data removes any leverage the company would have from a backup.  In addition, a company can never have a full guarantee that their data was deleted.  Both sides of the interaction know this, so why do companies pay? Research suggests that fear of the public’s response to a data breach is a major factor.  The backlash against companies who have lost sensitive data to hacks in the past has been severe.  This public pressure combined with hope for a return to before the security breach took place is part of what pushes companies to make deals that are not in their best interest.

So what should you do if a ransomware attack breaches your company’s security? First of all, do not engage with the hackers.  Their goal is to make money, not to help you.  Second, contact a legal expert to understand what liability you might have, and what your options are.  Finally, invest in your security.  Once data has been stolen, it is difficult to get back to ‘normal’.  Prevention is key to keeping you and your data safe.  If you or your company are in need of increased security, you can always reach out to us at info@optfinity.com.

FWD: Hackers Abusing Email Forwarding

By -- 2020-12-23 in Blog

We’ve written a lot of posts about how hackers are infiltrating corporate data and systems, but we haven’t spent much time discussing how they monetize that access.  A recent article discusses how a group of hackers used their access to their victim’s email services to the tune of $1.7 billion in losses.

Threat actors first gain access to an e-mail network through social engineering, the process of manipulating individuals within an organization to gain access to sensitive information or areas.  Once they have that access, the threat actor observes the organization’s pattern of communication so that they can mimic it.  At that point, the infiltrators will impersonate an employee to redirect payments to fraudulent bank accounts

The FBI sent an alert highlighting the dangers of this e-mail forwarding technique, stating that:

“The web-based client’s forwarding rules often do not sync with the desktop client, limiting the rules’ visibility to cybersecurity administrators. While IT personnel traditionally implement auto-alerts through security monitoring appliances to alert when rule updates appear on their networks, such alerts can miss updates on remote workstations using web-based email.”

We need to internalize how impactful these hacks are.  We also need to contrast those costs with the relative cheapness of how to prevent them. While only 7% of spear-phishing attacks use this technique, it is a remarkably effective one.  The almost 2 billion dollars in losses caused by this type of hack makes it the single costliest kind of attack in the past two years.

If you want to prevent these kinds of attacks at your own business, there are several important steps you can take.

  1.  Ensure that your mobile and desktop version of your email application can synchronize with each other, and have the latest updates.
  2.  Set up your email to flag communications where the sender’s address and addresses from replies do not match.
  3.  Enable multi-factor authentication.

Google’s Blackout: What Caused It?

By -- 2020-12-20 in Uncategorized

For 45 minutes on Monday morning, a variety of Google services were inaccessible across Europe and North America.  Google Search, Gmail, and a variety of Drive programs were all down.  Google’s physical devices also reported critical errors during the outage.  Initial reports blamed this on an error in the service’s authentication system, but a new report from the company shows that the problem was more widespread than initially thought.Google revealed that the root issue was a flaw with the company’s storage management system.  The issues only cascaded from there: limiting the authentication system’s capacity meant that the entire identity-management system was broken.  All users of Google Cloud Platform and Google Workspace at the time of the outage were affected.

So what lessons do this outage teach?

Big Tech Companies Aren’t Infallible

This is the third major failure in as many months, along with the five hours Amazon Web Services was disrupted in November and Microsoft Azure’s outage in October.  It can be tempting to trust blindly when a company has a track record of reliability and success, but track records won’t keep you afloat if a failure occurs.

Diversify and Monitor

If all your tools for support, monitoring, servicing, collaborating, etc. are on the same platform, you’ll be wiped out by those platform’s errors.  While it can be tempting to unify your systems for simplicity’s sake, your monitoring tools should always be separate so that you can be notified in case of an outage.  End-to-end visibility is the goal.

Backups Are Your Friend!

Having independent access to your data is crucial when your cloud host fails.  Backups create overlapping coverage so that no one failure impacts your company.  On top of that need for access, backups remove any worries about losing data that’s stored remotely.

 

In short, these failures should keep us from becoming complacent.  Security isn’t just about preventing attacks, it’s about preventing all disruptions in service. Take care of your technology, be aware of what these outages can do to your business, and take steps to prevent failure before it happens.

TA542: It’s Spear-Phishing Season Again.

By -- 2020-12-10 in Blog

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.

Is Zoom Back in Business?

By -- 2020-11-30 in Blog, Uncategorized

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.
