Gearing up for phishing scams in tax season

Paying and filing taxes is already annoying without the threat of refund fraud or identity theft. But phishing schemes, especially during tax season, have become so widespread that you’ve probably already received spoofed emails or calls during the last few years. To maintain the security of your business, you and your employees need to be extra cautious with the emails you receive at tax time.

Phishing baits to watch out for

Phishing attacks often consist of fabricated or compromised emails sent to finance/payroll or human resources employees that are made to look like they’re from an executive in your company. The message might contain a request to forward employee records, including their W-2 forms, but that’s not all…

Another common scheme, which doesn’t only happen during tax season, involves getting a call from a person declaring to be an IRS employee. And no, caller IDs won’t save you because they can forge that, too. The phisher will inform you that you owe them cash from back taxes and they will threaten legal action if you don’t pay via credit card at that instant.

Always remember, the IRS will never contact you on the phone to let you know that you owe them money. And they certainly won’t threaten you or demand payment over the phone. If they really need to notify you of such matters, they’ll use the postal service and will give you a chance to discuss payment terms.

Standard protection protocols

Don’t worry, the usual security measures against these phishing scams are pretty easy to integrate into your business. Begin by developing a policy that bans the request of private details through email. If an employee ever requires such info, they should get in touch with the person directly, follow your established protocols for the transfer of sensitive information, and minimize the number of people involved in the transaction.

Taking security a step further

Data loss prevention (DLP) systems are also valuable weapons against these types of phishing attacks. They evaluate traffic going in and out of your company, such as web usage, emails and instant messages, and virtually anything sent on your network. DLP systems can filter out private details, including Social Security numbers, and stop them from being sent out.

But beware, DLP systems come with a minor drawback, as they can also block legitimate traffic, like when your accounting department sends tax info to your CPA. Fortunately, an MSP like us can properly segregate the good and the bad traffic to avoid confusing and/or frustrating your employees.

Phishing schemes may be a normal occurrence during tax season, but that doesn’t mean you can’t do anything about it. Don’t let the vulnerabilities in your business, particularly the human element, fall prey to cybercriminals. Send us a message right away and we’ll conduct an assessment of the security of your business, as well as design a risk management plan to help counter future complications.

Lessons learned from the WannaCry malware

WannaCry is one of the few malware campaigns to become a household name. It’s educated countless people on the reality of ransomware and the vulnerability of their data. If you’re still worried about whether you’re at risk, we’ve collected everything you need to know right here.

Ransomware review

Ransomware is a specific type of malware program that either encrypts or steals valuable data and threatens to erase it or release it publicly unless a ransom is paid. We’ve been writing about this terrifying threat for years, but the true genesis of ransomware dates all the way back to 1989.

This form of digital extortion has enjoyed peaks and troughs in popularity since then, but never has it been as dangerous as it is now. In 2015, the FBI reported a huge spike in the popularity of ransomware, and healthcare providers became common targets because of the private and time-sensitive nature of their hosted data.

The trend got even worse, and by the end of 2016 ransomware had become a $1 billion-a-year industry.

The WannaCry ransomware

Although the vast majority of ransomware programs rely on convincing users to click compromised links in emails, the WannaCry version seems to have spread via more technical security gaps. It’s still too early to be sure, but the security experts at Malwarebytes Labs believe that the reports of WannaCry being transmitted through phishing emails is simply a matter of confusion. Thousands of other ransomware versions are spread through spam email every day and distinguishing them can be difficult.

By combining a Windows vulnerability recently leaked from the National Security Agency’s cyber arsenal and some simple programming to hunt down servers that interact with public networks, WannaCry spread itself further than any malware campaign has in the last 15 years.

Despite infecting more than 200,000 computers in at least 150 countries, the cyberattackers have only made a fraction of what you would expect. Victims must pay the ransom in Bitcoins, a totally untraceable currency traded online. Inherent to the Bitcoin platform is a public ledger, meaning anyone can see that WannaCry’s coffers have collected a measly 1% of its victims payments.

How to protect yourself for what comes next

Part of the reason this ransomware failed to scare users into paying up is because it was so poorly made. Within a day of its release, the self-propagating portion of its programming was brought to a halt by an individual unsure of why it included a 42-character URL that led to an unregistered domain. Once he registered the web address for himself, WannaCry stopped spreading.

Unfortunately, that doesn’t help the thousands that were already infected. And it definitely doesn’t give you an excuse to ignore what cybersecurity experts are saying, “This is only the beginning.” WannaCry was so poorly written, it’s amazing it made it as far as it did. And considering it would’ve made hundreds of millions of dollars if it was created by more capable programmers, your organization needs to prepare for the next global cyberattack.

Every single day it should be your goal to complete the following:

  • Thorough reviews of reports from basic perimeter security solutions. Antivirus software, hardware firewalls, and intrusion prevention systems log hundreds of amateur attempts on your network security every day; critical vulnerabilities can be gleaned from these documents.
  • Check for updates and security patches for every single piece of software in your office, from accounting apps to operating systems. Computers with the latest updates from Microsoft were totally safe from WannaCry, which should be motivation to never again click “Remind me later.”
  • Social engineering and phishing may not have been factors this time around, but training employees to recognize suspicious links is a surefire strategy for avoiding the thousands of other malware strains that threaten your business.

Revisiting these strategies every single day may seem a bit much, but we’ve been in the industry long enough to know that it takes only one mistake to bring your operations to a halt. For daily monitoring and support, plus industry-leading cybersecurity advice, call us today.

This fake Google app is really a phishing scam

If employee training and education isn’t an integral part of your cybersecurity strategy, a recent scam might force you to reconsider. Instead of relying on complicated programming code to steal and destroy data, hackers are increasingly relying on human errors to get the job done. Even well-trained users are falling for the most recent ploy, take a look.

Broadly defined, “phishing” is any form of fraud in which an attacker tries to learn information such as login credentials or account information by masquerading as a reputable entity or person in email, IM or other communication channels.

These messages prey on users who click links, images and buttons without thoroughly investigating where they lead to. Sometimes the scam is as simple as an image with a government emblem on it that links to a website containing malware. Just hovering your mouse over the image would be enough to see through it. But some phishing schemes are far more difficult to recognize.

The Google Defender scam

Recently, an email spread to millions of Gmail accounts that almost perfectly imitated a message from Google. The text read:

“Our security system detected several unexpected sign-in attempts on your account. To improve your account safety use our new official application “Google Defender”.

Below that was a button to “Install Google Defender”. What made this scheme so hard to detect is that the button actually links to a totally legitimate site…within Google’s own framework. When third-party app developers create Gmail integrations, Google directs users to an in-house security page that essentially says, “By clicking this you are giving Google Defender access to your entire inbox. Are you sure you want to do this?”

Even to wary users, the original message looks like it came from Google. And the link took them to a legitimate Google security page — anyone could have fallen for it. The Gmail team immediately began assuring users that they were aware of the scam and working on eradicating it and any potential copycats.

There’s no happy ending to this story. Although vendors and cybersecurity experts were able to respond to the crisis on the same day it was released, millions of accounts were still affected. The best way to prepare your business is with thorough employee training and disaster recovery plans that are prepared to respond to a breach.

Sly phishing attack catching users off guard

You pay close enough attention to the links you click to avoid clicking on something like goolge.com or evrenote.com…right? Because if you’re not, you could end up exposing your computer or smartphone to a host of malware. The newest phishing attack strategy is the worst of all, and can catch even the most astute users off guard.

What are homographs?

There are a lot of ways to disguise a hyperlink, but one strategy has survived for decades — and it’s enjoying a spike in popularity. Referred to as “homographs” by cybersecurity professionals, this phishing strategy revolves around how browsers interpret URLs written in other languages.

Take Russian for example, even though several Cyrillic letters look identical to English characters, computers see them as totally different. Browsers use basic translation tools to account for this so users can type in non-English URLs and arrive at legitimate websites. In practice, that means anyone can enter a 10-letter Cyrillic web address into their browser and the translation tools will convert that address into a series of English letters and numbers.

How does this lead to phishing attacks?

Malicious homographs utilize letters that look identical to their English counterparts to trick users into clicking on them. It’s an old trick, and most browsers have built-in fail-safes to prevent the issue. However, a security professional recently proved that the fail-safes in Chrome, Firefox, Opera and a few other less popular browsers can be easily tricked.

Without protection from your browser, there’s basically no way to know that you’re clicking on a Cyrillic URL. It looks like English, and no matter how skeptical you are, there’s no way to “ask” your browser what language it is. So you may think you’re clicking on apple.com, but you’re actually clicking on the Russian spelling of apple.com — which gets redirected to xn—80ak6aa92e.com. If that translated URL contains malware, you’re in trouble the second you click the link.

The solution

Avoiding any kind of cybersecurity attack begins with awareness, and when it comes to phishing, that means treating every link you want to click with skepticism. If you receive an email from someone you don’t know, or a suspicious message from someone you do, always check where it leads. Sometimes that’s as simple as hovering your mouse over hyperlink text to see what the address is, but when it comes to homographs that’s not enough.

In the case of homographs, the solution is unbelievably simple: Manually type in the web address. If you get an email from someone you haven’t heard from in 20 years that says “Have you checked out youtube.com??”, until your browser announces a fix, typing that URL into your browser’s address bar is the only way to be totally sure you’re safe.

For most, this trend feels like yet another development that justifies giving up on cybersecurity altogether. But for small- and medium-sized businesses that have outsourced their technology support and management to a competent and trustworthy IT provider, it’s just another reason to be thankful they decided against going it alone. If you’re ready to make the same decision, call us today.

Cyber-crime and social engineering

2016october7_security_cFor as long as there have been cybercriminals, there have been social engineers, or people who use tricks and scams to force other people to volunteer sensitive information. There are several ways to use social engineering to acquire valuable information like account passwords and bank accounts, but avoiding these scams comes down to one thing: training. Let’s take a look at some of the easiest ways for your employees to avoid one of these scams.

As more and more of our information moves into the digital realm, criminals are turning to social engineering to trick people into trusting them with their delicate information. People often trust others too easily and make themselves the targets of easy attacks from criminals. These attacks may come in the form of messages, baiting scenarios, fake company responses, and many others.

Most often, messages are sent to users in the form of an email that might contain a link or something to download. Although they may look legitimate, these emails often contain viruses; once the link is opened or you attempt to download it, a virus latches onto your computer, giving its creator free access to your email account and personal information.

Emails such as these can also come with a compelling story about needing help, winning the lottery, or even paying taxes to the government. Under the veil of legitimacy, criminals will ask you to trust them with your account details so they can either reward you or help you avoid fines and punishments. What you actually get is a bad case of identity theft.

In another scenario, criminals will bait their targets with “confidential information regarding their account.” This may come in the form of fake company messages that appear to be responses to your claims, which are followed up by a request for login details. While victims believe they are slamming the door on a crime by providing their information, they’ve actually provided their attackers with the keys.

There are several ways people can avoid becoming victims of social engineering. First, always ensure that you delete all spam from your email, and thoroughly research sources before responding to claims from a company — even if it seems like the one you normally use.

The same applies for links. Confirm the destination of any link before clicking on it. Sites like bit.ly are often used to shorten long and cumbersome links, but because users have grown accusomted to them they are often used to hide malacious misdirections.

Never give out sensitive information that includes your password, bank information, social security, or any other private details. No respectable financial institution will request this type of information through email or a site other than their own. If you’re unsure, navigate away from the page you’ve been sent to and visit the page you believe to be making the request. If the address doesn’t have the letter ‘s’ after ‘http,’ it’s likely a scam.

Last but not least, check that all your devices are protected by the most recent antivirus software. While the strength of social engineering lies in the fact that it’s people-driven rather than technology-driven, antivirus software can help detect and prevent requests from known cybercriminals.

Cyber security is essential to the success of any modern business. Don’t let yourself become victim to criminals who have mastered the art of social engineering. While we’re proud of our extensive experience as technology professionals, we also have more than enough expertise to keep your business safe from those who are using people-based exploits.

9 cybersecurity terms everyone must know

2016september21_security_cEveryone, from doctors to lawyers, needs to continue learning to stay ahead of the times. Business owners might have it worst of all, oftentimes needing to stay on top of several industries to keep their company running. Keep reading for a refresher on all the latest trends and buzzwords used in the cybersecurity sector.

Malware

For a long time, the phrase ‘computer virus’ was misappropriated as a term to define every type of attack that intended to harm or hurt your computers and networks. A virus is actually a specific type of attack, or malware. Whereas a virus is designed to replicate itself, any software created for the purpose of destroying or unfairly accessing networks and data should be referred to as a type of malware.

Ransomware

Don’t let all the other words ending in ‘ware’ confuse you; they are all just subcategories of malware. Currently, one of the most popular of these is ‘ransomware,’ which encrypts valuable data until a ransom is paid for its return.

Intrusion Protection System

There are several ways to safeguard your network from malware, but intrusion protection systems (IPSs) are quickly becoming one of the non-negotiables. IPSs sit inside of your company’s firewall and look for suspicious and malicious activity that can be halted before it can deploy an exploit or take advantage of a known vulnerability.

Social Engineering

Not all types of malware rely solely on fancy computer programming. While the exact statistics are quite difficult to pin down, experts agree that the majority of attacks require some form of what is called ‘social engineering’ to be successful. Social engineering is the act of tricking people, rather than computers, into revealing sensitive or guarded information. Complicated software is totally unnecessary if you can just convince potential victims that you’re a security professional who needs their password to secure their account.

Phishing

Despite often relying on face-to-face interactions, social engineering does occasionally employ more technical methods. Phishing is the act of creating an application or website that impersonates a trustworthy, and often well-known business in an attempt to elicit confidential information. Just because you received an email that says it’s from the IRS doesn’t mean it should be taken at face value — always verify the source of any service requesting your sensitive data.

Anti-virus

Anti-virus software is often misunderstood as a way to comprehensively secure your computers and workstations. These applications are just one piece of the cybersecurity puzzle and can only scan the drives on which they are installed for signs of well known malware variants.

Zero-day attacks

Malware is most dangerous when it has been released but not yet discovered by cybersecurity experts. When a vulnerability is found within a piece of software, vendors will release an update to amend the gap in security. However, if cyber attackers release a piece of malware that has never been seen before, and if that malware exploits one of these holes before the vulnerability is addressed, it is called a zero-day attack.

Patch

When software developers discover a security vulnerability in their programming, they usually release a small file to update and ‘patch’ this gap. Patches are essential to keeping your network secure from the vultures lurking on the internet. By checking for and installing patches as often as possible, you keep your software protected from the latest advances in malware.

Redundant data

When anti-virus software, patches, and intrusion detection fail to keep your information secure, there’s only one thing that will: quarantined off-site storage. Duplicating your data offline and storing it somewhere other than your business’s workspace ensures that if there is a malware infection, you’re equipped with backups.

We aren’t just creating a glossary of cyber security terms; every day, we’re writing a new chapter to the history of this ever-evolving industry. And no matter what you might think, we are available to impart that knowledge on anyone who comes knocking. Get in touch with us today and find out for yourself.

Don’t let hackers fool you with these tricks

2016August18_Security_CAccording to several reports, the volume of malicious cyber attacks have increased since the beginning of the Rio Olympics. And even though our devices have the latest network security systems, hackers have a cunning trick up their sleeves — social engineering. Unlike malware and other viruses, social engineering tricks people into divulging sensitive data to hackers. Unfortunately, businesses are also vulnerable to various social engineering tactics. As a business owner, you should be vigilant of these common scams used by hackers.

Phishing
Phishing scams are perhaps the most common type of social engineering attack. Usually seen as links embedded in email messages, these scams lead potential victims into seemingly trustworthy web pages, where they are prompted to fill in their name, address, login information, social security number, and credit card number.

Phishing emails often appear to come from reputable sources, which makes the embedded link even more compelling to click on. Sometimes phishing emails masquerade as government agencies urging you to fill up a personal survey, and other times phishing scams pose as false banking sites. In fact earlier this year, fraudulent Olympics-themed emails redirected potential victims to fake ticketing services, where they would eventually input their personal and financial information. This led to several cases of stolen identities.

Tailgating

What’s the best way to infiltrate your business? Through your office’s front door, of course! Scam artists can simply befriend an employee near the entrance of the building and ask them to hold the door, thereby gaining access into a restricted area. From here, they can steal valuable company secrets and wreak havoc on your IT infrastructure. Though larger enterprises with sophisticated surveillance systems are prepared for these attacks, small- to mid-sized companies are less so.

Quid pro quo

Similar to phishing, quid pro quo attacks offer appealing services or goods in exchange for highly sensitive information. For example, an attacker may offer potential targets free tickets to attend the Olympic games in exchange for their login credentials. Chances are if the offer sounds too good to be true, it probably is.

Pretexting

Pretexting is another form of social engineering whereby an attacker fabricates a scenario to convince a potential victim into providing access to sensitive data and systems. These types of attacks involve scammers who request personal information from their targets in order to verify their identity. Attackers will usually impersonate co-workers, police, tax authorities, or IT auditors in order to gain their targets’ trust and trick them into divulging company secrets.

The unfortunate reality is that fraudsters and their social engineering tactics are becoming more sophisticated. And with the Olympics underway, individuals and businesses alike should prepare for the oncoming wave of social engineering attacks that threaten our sensitive information. Nevertheless, the best way to avoid these scams is knowing what they are and being critical of every email, pop-up ad, and embedded link that you encounter in the internet.
