An Update Turned This App Into Malware. Were You Affected?

By -- 2021-05-20 in Uncategorized

Popular Barcode Scanner App Turns Malicious, Affects Millions

A once-trusted barcode and QR code scanner app has turned on its users, compromising nearly 10 million devices.

Lavabird Ltd’s Barcode Scanner gained popularity on the Google Play Store as a go-to solution for Android users. Unlike Apple’s newer devices, Android phones don’t come with built-in QR code or barcode scanning capabilities, making apps like Lavabird’s essential for many consumers. For years, the app maintained a clean security certificate, earned thousands of positive reviews, and showed no signs of malicious code.

Security-conscious users trusted the app—until a routine update transformed it into malware.

Malwarebytes Identifies the Threat

In late December, Malwarebytes, a cybersecurity company focused on malware detection and prevention, started receiving complaints from users. These users reported that their devices began launching ads automatically through the built-in internet browser.

This behavior resembled “malvertising”—a form of malware usually linked to newly installed apps. However, affected users hadn’t downloaded any new apps recently. Malwarebytes eventually traced the source of the infection to Lavabird’s Barcode Scanner, which had been operating safely on devices for years.

Removing the App Removes the Threat

Fortunately, uninstalling the app appears to eliminate the malware. However, the bigger concern lies in how easily an app built up trust, only to later deliver a malicious update without raising red flags.

For today’s consumers, checking reviews and permissions before downloading an app no longer offers sufficient protection.

How to Protect Yourself and Your Devices

Start by reviewing the apps on your phone. Delete any that you no longer use, and keep an eye out for unusual behavior after installing or updating an app.

If you manage a business and issue work phones to employees, consider restricting app downloads and updates. Doing so gives you more control over device performance and security.

Combo Phishing Attacks Target VPN

By -- 2021-05-10 in Blog

Everyone is familiar with the uptick in email phishing scams that have come with the COVID-19 pandemic. Workers and employers alike are adapting their security practices to defend company and consumer data. However, cybercriminals are adapting too. One group is combining phone calls and custom phishing sites to corporate VPN credentials. This group acts on a ‘bounty’ system, where a person hires the group to attack a specific company. Worst of all? The attacks have been remarkably successful.

So what does this attack look like? First, the group receives a request to target a specific company. They then create a site that mimics that company’s VPN portal. Once the setup is finished, the group makes a series of phone calls to employees working from home. The callers inform the target that they are with the company’s IT department trying to troubleshoot VPN issues. They then try to coerce the target into revealing their log-in information over the phone or entering their credentials into the fake website. At that point, the phishers have access to the company’s internal information.

This combination of fake websites and fraudulent calls have been more effective than traditional email phishing attempts. Despite that, workers can take steps to prevent being caught up in this scheme. If you receive a call from someone you don’t recognize who is asking for sensitive information, take these steps before disclosing anything.

  1. Ask for the caller’s name.
  2. Hang up and call your company’s IT department or managed services provider—do not just redial the number that called you.
  3. When you reach your company’s tech support, explain that you received a call from someone claiming to be from their department. Once you explain what the caller was asking for, they can confirm whether the call was legitimate.

If the call was legitimate, no harm done! You can continue troubleshooting the issue with only a small delay. If not, you’ve saved yourself and your company a lot of trouble. If you’re concerned about your company’s vulnerability to these types of combination attacks, OptfinITy is here to help!

Add Me as an Admin: A 5-Word IT Horror Story

By -- 2021-04-30 in Uncategorized

Why Can’t I Be the Admin of My Own Computer?

Everyone who works in IT dreads hearing this question. Admin privileges provide powerful access, enabling major system changes like editing files and downloading software.

Calling your IT provider just to type in a passcode can feel frustrating. If your job involves frequent software downloads, it’s easy to see why you might want to “cut out the middleman.” But what’s the worst that could happen?

Principle of Least Privilege

No two IT providers are exactly the same—each operates with unique approaches. Still, many core principles of IT and cybersecurity remain consistent across the industry. One of these is the principle of least privilege. This concept ensures that users receive only the level of access necessary to perform their tasks. While some users may need admin-level privileges, most do not.

The principle of least privilege aims to minimize the damage that any single account can inflict on a system. For example, a user might delete an important file or accidentally download malware. In other cases, a cybercriminal may compromise the account. By applying the principle of least privilege, organizations can reduce or even prevent these risks.

Every additional admin account on a device increases its vulnerability to threats. When that device serves a business purpose, these risks extend to the entire organization. Threat actors with admin access can make destructive changes that ripple across the company, potentially causing widespread damage before anyone can stop them—if they can stop them at all.

The Bottom Line

Is the principle of least privilege inconvenient? Yes. But it’s far less inconvenient than dealing with a major security breach.

Your Security Toolkit: Password Manager

By -- 2021-04-20 in Blog

With work-from-home becoming the new normal, companies are scrambling to adapt their security practices.  Some are hiring an outside firm to handle their transition, while others are trying to cobble together an in-house solution.  Security is difficult to maintain at the best of times, and 2020 is most definitely not the best of times.  Security experts have noticed a large increase in cyberattacks over the course of 2020.  Threat actors have created over 5.5 million Trojan attacks.  Malware has increased by 2000%.  Threat actors are taking advantage of the pandemic, resulting in the loss of crucial data and massive amounts of money.  With all of these threats out there, what can you do to keep your company safe?

In times like these, you need expertise.  While you could hire an outside firm to handle your transition, small businesses often can’t afford that option.  This series of blog posts will go over some of the steps you can take to keep your company’s data safe without going over-budget.  If you’re looking for an in-depth explanation of any of these topics, you can leave a comment here or on any of our social media posts.  We also have a free webinar series starting in January that will cover this transition to the “New Normal” that you can sign up for soon. In the meantime, we’ll be discussing a new step you can take to improve your business’s security every week.

Consider A Password Manager

Do you know how common bad passwords are?  Over 25 million people use “123456”, and another 8 million use “123456789”.  4 million people are still using “password” to secure their data.  Each of these can be cracked in under a second — not much better than no password at all.  One common reason for why people choose non-secure terms for password is their difficulty in remembering complex passwords.  If your company’s security protocols require a certain degree of password complexity, workers might then store their passcodes in a text document that itself is not password-protected.  So how do you solve these issues? A password manager!

A password manager allows employees to generate, store, and fill passwords for various sites. This allows each employee to easily follow uniqueness and complexity requirements. Some password managers even allow employees to securely share passwords with other employees, without allowing them to see the password itself.  Furthermore, password managers are usually either free or available at a low monthly cost, making them a fantastic option for small businesses on a budget. In short, a password manager is the way to go for anyone concerned with improving business security.

Do you use a password manager? Are there questions or concerns you have about using one? Leave a comment here, or email us at info@optfinITy.com.  We’d love to hear from you!

 

Homeland Security Gives SolarWinds Update

By -- 2021-04-10 in Blog

The SolarWinds Cyberattack: A Wake-Up Call for the Tech Industry

In late 2020, a massive cyberattack targeted SolarWinds, a creator of popular networking software used by over 300,000 customers worldwide, including 412 Fortune 500 companies. Initially, many believed the attack focused on the software corporation and its high-profile clients due to malicious code embedded in SolarWinds’ software. The overlap between SolarWinds’ clientele and the victims reinforced this assumption.

Unraveling the Scope of the Attack

Recent discoveries revealed that over one-third of the known victims had no connection to SolarWinds, suggesting multiple, yet unidentified, attack vectors. Even significant government entities, such as the National Telecommunications and Information Administration and the Treasury Department, reported breaches. Hackers gained limited access to sensitive data, including internal government emails. Despite ongoing investigations, the complete list of compromised data, the identities of the attackers, and the methods they used remain uncertain.

The Ripple Effect of Far-Reaching Cyberattacks

Far-reaching cyberattacks like this create chaos for all affected. Private citizens may face the exposure of sensitive data to malicious actors, corporations suffer financial losses and a hit to consumer trust, and national security risks remain unresolved. SolarWinds continues investigating the root cause and has pointed to Microsoft’s cloud as a possible attack vector. However, federal law enforcement and Microsoft have yet to confirm this claim.

Moving Forward: Cybersecurity Vigilance Is Key

As of early 2021, the SolarWinds attack leaves many unanswered questions, from the full list of impacted entities to the attackers’ motivations. In the face of uncertainty, organizations must prioritize robust cybersecurity measures and stay informed about emerging threats.

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.
