Phishing

Inside The Anatomy Of The Human Firewall

Thomas Fox is president of Tech Experts, southeast Michigan’s leading small business computer support company.

Each year, around 61% of small businesses become the victims of a malware attack. While many small businesses may think no one would ever come after them because of their size, know that over half of the total global attacks hit small businesses and, for thieves, getting access to your systems is becoming increasingly lucrative.

Companies collect more about customers than ever before: medical history, financial records, consumer preferences, payment information, and other confidential information.

Some of this information could be used in malicious ways to either harm your business or directly harm the customers, so we all understand that we must protect it from cyberattacks.

Creating a human firewall is the best way to keep your system and data safe, but what exactly is a human firewall, why do you need one, and how can you build one? Let’s take a look! [Read more…] about Inside The Anatomy Of The Human Firewall

Researchers Turning To Algorithms To Combat Phishing

Chris Myers is a field service technician for Tech Experts.

Phishing is a type of social engineering attack used to steal user information such as login credentials, bank account information, or credit card numbers. The most commonly seen phishing attack is when an attacker, posing as a legitimate source, tricks a victim into clicking on a malicious link in an email. Once clicked, the link installs malware on the user’s computer and possibly gives the attacker access to other devices on the same network.

Often, the link opens a website owned by the attacker, specifically designed to look like a normal login or account validation page. However, when users enter their information into this website, all they are doing is giving that information directly to the attacker.

Phishing emails have been around since the dawn of the Internet, even having a paper and presentation discussing their use at the 1987 conference for the International HP Users Group, “Interex.”

While the basic premise hasn’t changed since then, attackers have had decades to improve their technique and automated delivery systems.

A New Defense
Jeremy Richards of the mobile device security company Lookout has been developing a novel solution to this problem. Lookout records the network traffic of over 60 million mobile applications and, as such, has a large amount of real-time data it can analyze.

After manually tracking phishing websites through this network, Richards discovered many telltale digital signs of phishing websites. He started creating tools to assist in this detection, but those quickly evolved into their own automated search engine.

The program now goes through several steps to algorithmically narrow down and positively identify malicious websites. For example, the program will check new domains (website addresses) for misspellings of technology or financial companies, or special characters used in place of normal lettering.

Once it spots a suspicious website, it will take a screenshot of the homepage and then automatically search for the logos of thousands of companies. Phishing websites almost always try to look official by using the actual logos from companies like Apple, Microsoft, and Google.

Once a site is confirmed to be malicious, Lookout can report them to the authorities, download the specific phishing code used by the attackers, then look for that code in future scans to find additional websites.

As phishing attacks occur with increasing frequency, these automated solutions will be necessary for us to stand any chance at stemming the tide of cybercrime.

How To Spot Phishing Emails
Here are some common characteristics of phishing emails that you can identify:

Poor grammar – Since most emails aren’t composed by native English speakers, they usually contain many grammar, spelling, and capitalization mistakes, along with unusual phrasing.

Generic or informal greetings – If a message doesn’t address you by name, it’s another sign that it is from an unknown attacker.

Sense of urgency – Most phishing emails want you to rush through the message and click on a link without looking at it too closely.

Hyperlinks – Hover over any links to make sure they go where they say they are going.

Attachments – Many phishing emails will include malware in attachments.

Unusual sender – If it’s from someone you don’t know, pay extra attention to the contents.

Google Study Reveals Phishing Attacks Are The Biggest Threat To Web Security

A recent study by Google and UC Berkeley suggests that cyber thieves are successfully stealing 250,000 valid usernames and passwords every week.

The study, which was based on 12 months of login and account data that was found on criminal websites and forums, aimed to ascertain how the data had been hacked and the actions that can be employed to avoid criminal activity in the future.

Google claims the research is vital for developing an understanding of how people fall victim to scammers and hackers and will help to secure online accounts.

The research found that, over a 12-month period, keyloggers (programs that monitor every keystroke that someone make on a computer) stole 788,000 account credentials, 12 million were harvested via phishing (emails or phone calls that con people into handing over confidential data), and an incredible 1.9 billion were from breaches of company data. The study found the most productive attacks for cyber-thieves came from phishing and keylogging. In fact, in 12%-15% of cases, the fraudsters even obtained users’ passwords.

Malicious hackers had the most success with phishing and were able to pick up about 234,000 valid usernames and passwords every week, followed by keyloggers who managed to steal 15,000 valid account details per week.

Hackers will also look to gather additional data that could be useful in breaching security measures, such as the user’s Internet address (IP), the device being used (Android versus Apple) and the physical location. Gathering this data, however, proved far harder for those with malign intent.

Of the people whose credentials were secured, only 3.8% also had their IP address identified, and less than 0.001% had their detailed device information compromised.

Google said in a follow-up blog post that the research would be used to improve the way it detects and blocks attempts to misappropriate accounts.

Historical data of the physical location where users logged on and the devices they used will increasingly be used as part of a range of resources that users can use to secure their accounts.

The research, however, did acknowledge that the account hacking problem was ‘multi-pronged’ and would require countermeasures across a number of areas including corporate networks.

Education of users is set to become a ‘major initiative’ as the research also revealed that only 3.1% of people whose account had been hijacked subsequently started using enhanced security measures such as two-step authentication (Google authenticator or a similar service) after control of a stolen account was regained.

Helpful Tech Tips To Prevent Phishing

Many of us have clicked on an email that appeared authentic, but was not. Those fortunate enough to identify any suspicious elements before an attachment is opened or a link is clicked are the lucky ones. But, sometimes, we don’t notice those little things and click things we shouldn’t.

These trick emails are one method of an effective scheme called phishing, run by cybercriminals to get information about you or your company. Even worse, this information is then bought and sold to the highest bidder to do with it as they wish.

At best, an ad agency might send some extra spam emails your way. At worst, your identity may be stolen or your company’s network may be left exposed for all sorts of trouble.

Fortunately, there are many things you and your workplace can do to avoid these phishing attempts.

Tips for Employers

Just asking employees to watch out for suspicious-looking emails doesn’t drive home the urgency of phishing.

Find recent news reports to share with your workforce. When an organization makes the front page for a data breach (usually because an employee opened an infected email), you can explain how something like that could happen to your organization. It’s well-timed, newsworthy, and will be on forefront your employee’s mind.

The best thing to do as an employer is to implement a program that encourages security awareness, education, and behavior modification.

Changing up how you deliver that message to employees can be quite helpful. Start with a monthly email, memo, or bulletin. Switch it up with in-person, individualized meetings. Using different approaches will help your message resonate with more employees. It is common to need to communicate a message multiple times for it to stick with everyone.

Tips for Employees

Social media can be your worst enemy. Social networks are abundant with personal information, putting it right at the fingertips of cybercriminals.

Do not post any birthdays, addresses, or any other personal information on these websites. We know many domain and personal accounts use these for passwords despite the easy availability. Even with privacy settings maxed, there is always a way for cyber criminals to obtain the information.

Additionally, cybercriminals are getting more creative, especially with phone numbers. It is becoming very common for criminals to call high-risk employees and ask for information. For example, some of these “phishers” will call and pretend they are from their company’s help desk and need to reset account credentials or “require verification” from the user.

When in doubt, don’t give anything out. If something seems off or you don’t know the person, ask for their contact information and look into it. In these cases, it’s better to be cautious than courteous.

Overall, phishing isn’t going anywhere and it should be incorporated into all online security training for workplaces. As long as people use social networks and email continues to be a primary workplace communication channel, phishing will be a top choice for cybercriminal’s data theft.

Gone Phishing! How To Spot A Phishing Scam

If you are a user that has been around for a while, there is a pretty good chance you’ve been targeted with a phishing scam. You may have a long lost relative in another country who left you millions – and all the executor of the estate needs is your banking information to send you your inheritance! Or a prince of a small country is trying to move some of his fortune and escape to America – and if you can help, you will be rewarded!

These are some oldies-but-goodies, however phishing scams have and will continue to get better and smarter.

There was a time when phishing scams almost always came filled with poor grammar, spelling errors, and writing that just seemed a little off. While these still exist, things have become harder to detect.

These scammers are always looking for your personal information. There are a few ways they can do this, but most of them begin with email spoofing, where a sender will mask their actual email address with a familiar one.

If it isn’t a spoofed email, it may come from an address that is very close to that of a known and trusted sender. This could have an extra letter or even just a period to try to trick you into completing whatever task they are using in an attempt to get your information. This could be something as simple as a link to “family photo” or video and it could very well open your system to different vulnerabilities.

Something like a keylogger, a program that tracks your keystrokes, can be almost undetected while also gathering your online banking or credit card information.

Lately, phishers and scammers have pulled out all the stops. There have been cases where phishers will not only spoof an email, but also documents. These can look pretty real, so take a close look.

A new long-shot, big-payoff scam is to spoof an email address of a financial institution to try to intercept money from home purchases. This is done with forged documents and a fake email. While it’s a long shot for something that big to happen, do big business in-person or through trusted secure communications.

What to watch for:

When you have email communication from a known sender that doesn’t quite add up (or doesn’t sound like them), don’t assume they’re just having an off day. One example: if you know your family member shares all of their photos on Facebook, would they really email you a link with little to no writing in the email?

Any “company” asking for any personal information or passwords through email should also raise red flags. While this might seem obvious if the email address doesn’t match, a spoofed email address can make this trick easier to fall victim to.

Also, be wary of anyone asking for your bank account number via email. Even if it is legitimate, there are other ways to send this information. Protect yourself by choosing a more secure method of communication.

What to do:

If something seems off, research it. If you get a weird email requesting something or asking you to click on a link, don’t assume it’s safe. If it’s from someone you know, ask them if they did send it.

If you are the one “sending,” check your Outbox or Sent folder. This is a good indication if the email came from you or someone you know.

Do You Have A Blind Spot In Your Security?

Security is only as good as its weakest link — one blind spot and a company can be compromised. It is important that each aspect of a company’s security is understood and up to date.

With the following best security practices, it can be better understood what to be aware of and how to better advance a company’s security.

From remote hackers, to in-person social engineering, and even your own e-mail, there are different methods of attacks and means of defense to maintain a company’s integrity.

Physical Security
The basic defense that predates IT security is physical security. Locked doors, restricted access, and watch patrol are some of the oldest methods to prevent aggressive physical security breaches.

Technology has only made physical security even better with security cameras, alarm systems, RFID badges, and biometric systems that identify a person from their physical being. Having the appropriate physical security is key to preventing and deterring break-ins and stolen items.

Social Engineering
With the right words and story, some people gain access to compromising areas and information that can give a company a real bad time.

Without a physical break-in or even a computer, social engineering works against human psychology, finding the vulnerabilities of staff and workers to trick and deceive their way past security. The best way to defend from this is to have a strong and easily understood security policy that educates staff and workers not give out credentials and access to unauthorized personnel.

Phishing
Billions of emails are sent out every day — promising a vacation, warning people about their bank accounts, or asking for charity — that are entirely design to steal or compromise a person or company. Phishing targets everybody, asking for credit card numbers, asking a person to sign in to their account on a fake site, or taking something in other ways.

Do not open emails or download email attachments with suspicious or unknown origins. If an email looks odd or is too good to be true, call or check a website directly to confirm if an email is legitimate.

Clicking or falling for phishing could end with a stolen identity, stolen money, or a locked PC or network demanding ransom money. Be smart and wise about checking emails.

Hackers
There are people that spend most of their day trying to break security codes, finding software loop holes, and other abstract means to force their way through digital security to gain illegal access to computers.

There are just as many (if not more) people working together to prevent such people from ever gaining access with new security measures and patches. To protect a PC or a company from hackers, always update your security definitions on Windows and antivirus software. Knowing what software to trust and what updates are needed are important ensuring digital security. We at Tech Experts make it our business to keep digital security online and updated at all times, so that no one has to fall victim to the unseen security threat.

Being aware of these different security risk and knowing how to defend from them can give a strong basis in understanding and learning in what needs to be done to keep a company or person secure.

Security is always evolving and changing, but having a modern understanding with security in place can make the difference between a secure environment and a risky work place that could come to a grinding halt when security is breached. Be safe, be smart, and be productive with good security.

Beware: Online Banking Phishing Schemes Are On the Rise

Banking online is a convenient and time saving way of managing and keeping track of your company’s finances.

Weak security practices, though, can make it more possible for cyber-thieves and hackers to steal your hard-earned money. It is important to make sure that all possible steps are taken to safeguard your company’s finances.

Online banking is a tool that many businesses utilize because of the ease, efficiency, and convenience it offers.

It’s a great way to manage finances in your day-to-day operations. Unforunately, as more businesses turn to online banking, cyberthieves and hackers who target small companies are becoming more adept at stealing from companies online.

Security experts are urging companies to beef up their security systems to keep them safe from cyber and identity theft.

The more companies rely on the Internet, especially when it comes to managing finances through online banking, the more prudent it is to take steps to prevent that hardearned money from being stolen or diverted to someone else’s account.

One tip experts give is to establish proper protocols for transacting with the bank, such as requiring two people to verify a transaction before it is approved.

This helps create a checks-and-balance system that hackers can’t bypass.

Having a dedicated workstation used for only online financial transactions is also recommended, as this lessens the likelihood of it being infiltrated by Trojans, viruses, spyware, and other malware that may come from the machine being used for other purposes.

Having the right anti-virus and antimalware software – and keeping it updated – also goes a long way in keeping your online banking transactions safe from unfriendly eyes.

Your finances are the lifeblood of your business. If you’re interested in how you can make your online banking experience more safe and secure, we’d be happy to sit down with you to discuss security solutions that are tailor-fit to your specific requirements and needs.

Phishing Schemes Are On The Rise

A phishing e-mail is an e-mail sent by a hacker designed to fool the recipient into downloading a virus, giving up their credit card number, personal information (like a social security number), or account or login information to a particular website.

Often these e-mails are well designed to look exactly like an official notification from the site they are trying to emulate.

For example, a recent phishing e-mail was circulated that appeared to come from Facebook stating that videos or photos of Osama Bin Laden’s death were posted online. These e-mails looked exactly like a legitimate Facebook e-mail and even appeared to come from “Facebookmail.com.”

Once you clicked on the e-mail the phishing site would attempt to install a virus on your machine.

And now due to recent security breaches with Sony and e-mail marketer Epsilion, phishing attacks are going to increase – and they are going to get more sophisticated and harder to distinguish from legitimate e-mails.

That’s because the hackers that were able to access the private databases of the above mentioned companies now have the name, e-mail and interests of the subscribers, and in some cases birthdays, addresses and more. That means a phishing e-mail can be personalized with relevant information that the user provided to Sony, making the e-mail appear to be more legitimate and the user more likely to click on the links provided and take the actions requested. Now more than ever it’s critical that you are wary of e-mail notifications and the actions they request you take. Even having good anti-virus software installed won’t protect you if you give your account information away freely.

 

 

Almost Every Small Business Can Expect To Get Hacked

Thomas Fox is president of Tech Experts, southeast Michigan’s leading small business computer support company.

Juniper Networks recently commissioned a study on small and medium company network security.

The startling result: Over 90% of US companies reported at least one security breach in the last year, with more than half indicating they experienced two or more significant security problems with their networks.

There’s a misconception among a lot of small business owners that they’re safe from cyber attacks, because small companies offer a smaller payback for hacking efforts.

Small business network security is usually lax

The reality is, security policies and procedures at small companies usually make them an easy and simple target for hackers.

While the payout isn’t as large as hacking TJ Maxx, invading a small business’ network usually takes a lot less effort, and the business lacks a sophisticated response system.

Why is hacking so easy?

A new technique, called spear phishing, let’s hackers target a small group of previously identified people. Sometimes, the attack goes after just a handful of people who work at the same company.

Spear phishing does away with the need for hackers to gain access to your passwords. As more companies start to use social media sites such as FaceBook and Twitter, hackers using spear phishing are finding it easier to “trick” unsuspecting employees into installing crimeware on their company computers. This crimeware let’s the criminals access the computer system directly. Once they have access to one machine on your network, it’s easy to connect to the others.

Recent attacks have highlighted the growing need for companies to implement network security controls to catch the bulk of socially engineered spear phishing attacks.

They also need to take measures to quickly detect and contain security breaches.

The first thing you’ll want to do to protect your business is implement a strong firewall (see Frank’s article on page two) that lets you assign security restrictions for users based on the content of websites, and even keywords that might be potentially dangerous.

The next thing to look at is your company’s acceptable use policy. This can be as simple as a few pages added to your employee handbook that outlines what is and isn’t acceptable behavior on your network.

The final thing to examine is your backup and disaster recovery plan. The hacker’s aren’t giving up, which means it’s time to plan for what comes after a security breach.

Avoiding Common Email Security Threats

Most companies today rely heavily on the use of email. Emailing is a very fast and cost effective form of communication for many different types of businesses.

Most companies use it as their main source of communication between employees. In fact, most employers do not realize the risk of using email.

Some risks range from viruses, hackers, to someone else just trying to gain a little information.

Here’s an overview of the most common email security threats in today’s Internet world.

Viruses
Viruses cause billions of dollars in damage to businesses every year.

Many corporate email systems are still quite vulnerable to viruses. In fact, in last year alone, an estimated 63 distinct email virus attacks hit the United States. These attacks come quickly and can spread quickly.

They mainly cause slowdowns across the internet. However some have been known to take down major corporation’s entire email systems.

Today’s viruses are very complex and often appear to be harmless such as personal notes, jokes, or promotions. While most viruses require recipients to download attachments in order to initiate infection and spread, some are designed to launch automatically with absolutely no user action required.

Spam
Studies have shown that 20 percent of corporate email is spam. A company that has a thousand employees could receive over two billion spam emails in a full year.

Most do not realize it until a lack of productivity ends up costing the companies billions of dollars each year.

While most spam is just annoying, some of it can be very dangerous. Most trick employees into opening malicious emails to spread faster. Also, many hackers have begun disguising viruses as spam.

Phishing
Phishing is used to trick a person into thinking the email is legit and came from a real website, usually asking the person to verify their password or to change some sort of account information.

Then, taking them to a fake website and stealing what you have typed in. This is the number one way people get their identity and personal information stolen.

Spyware
The main purpose of spyware is to install itself on the victim’s computer. It monitors all key strokes and mouse clicks so that they can later go back and collect usernames, passwords, credit card numbers and bank account numbers.

These infections can stay installed on computers for many months without an antivirus picking them up.  Most are detected and removed instantly if the user keeps their antivirus up to date.

Having a great antivirus that scans files as well as emails can help prevent virus attacks, phishing and spyware.

Users should also have an up to date spam filter that prevents the infection from getting to your inbox to begin with. And most importantly never open an email attachment you didn’t specifically request.

Also, pay attention to links inside emails that appear legitimate. Many times, phishers will send you an email that looks like it came from an official source. After clicking the links, you’re redirected to a site on the hacker’s network. This is often used to collect personal information and passwords.
