Very effective Social Engineering Scams

/in /by

It’s amazing how ingenious cybercriminals are, but the victims also need to take some responsibility for falling for these ruses, especially when the victim is a business that has failed to train its employees in cybersecurity measures.

10DRansomware

The stuff of science fiction is here: Who would have ever thought there’d ever be a such thing as criminals remotely stealing someone’s personal information (word processing files, any kind of image, etc.), scrambling it up via encryption, then demanding ransom in exchange for the remote “key” to “unlock” the encryption?

Payment is remotely by Bitcoin which can’t be traced. The payment is usually at least $500 and escalates the longer the victim waits.

The virus that poisons a computer to steal someone’s files is called ransomware, a type of malicious software (in this case, “Cryptolocker” and “CryptoDefense”). But how does this virus get into your computer in the first place?

It’s called social engineering: tricking users into allowing their computer to be infected, or duping them into revealing personal information.

Often, a phishing e-mail is used: It has an attention-getting subject line that entices the user to open it. The message contains a link. They click the link, and a virus is downloaded. Or, the link takes them to a site which then downloads the virus.

These e-mails, sometimes designed to look like they’re from the company the user works for, often go to workplace computers where employees get tricked. These kinds of attacks are lucrative to their instigators.

Funeral Fraud

If you wanted to notify a relative or friend that a mutually dear person has left this earth…would you send an e-mail or phone that person? Seems to me that heavy news like this would warrant a phone call and voice interaction.

So if you ever receive an e-mail from a funeral home indicating that a dear one to you has passed, and to click a link to the funeral home to learn details about the burial ceremony…consider this a scam.

Because if you click the funeral site link, you’ll either get redirected to the crook’s server because he’s already created an infected funeral looking site ahead of time. This is where a virus will be downloaded to your computer.

Vishing Credit Card Scam

You get a phone call. An automated voice identifies itself as your credit card company (they’ll say “credit card company” rather than the specific name). It then says something like, “We are investigating what appears to be a fraudulent charge on your card.”

They’ll ask if you made a particular purchase lately, then to hit 1 for yes and 2 for no. If you hit no, you’re told to enter your credit card number, three-digit security code and expiration date. You just fed a thief all he (or she) needs in order to go on an online or on-phone spending spree.

Ever order something via phone and all you had to give up was the credit card number, expiration date and security code? This trick is also aimed at employees. The calls come from an automated machine that generates thousands of these calls.

Healthcare Record Scam

You receive an e-mail that appears to be from your employer or healthcare provider that you get through work. This may come to you on your home computer or the one you use at work. The e-mail is an announcement of some enticing change in your healthcare plan.

The message may reference something personal about you such as marital status, income or number of dependents. When enough of these e-mails are pumped out with automated software, the personal situation of many recipients will square off with those identified in the e-mail, such as income and number of children. The user is then lured into clicking a link in the e-mail, and once that click is made…malware is released.

Facebook Company Group Scam

Scammers will scan Facebook and LinkedIn seeking out employees of a particular company and create a group. This groups purpose is for information gathering so scammers can penetrate a company’s facility or website. Once all the groups member join, the scammers will pose various innocuous questions and start palatable discussions that make everyone feel comfortable.

Over time scammers will direct these discussions to leak bits of data that allow criminals to enter a facility under a stolen identity or to contact specific employees who have advanced access to computer systems in an attempt to get usernames and passwords.

What is Ransomware?

/in /by

Imagine that you want to pull up a certain file on your computer. You click on the file and suddenly a notice flashes on your screen saying your computer has been compromised and in order to get your files back, you need to pay up some money. This, ladies and gentlemen, is ransomware, a nasty type of malware that, unfortunately, hackers love to use.

4DRansomware is malicious software created by a hacker to restrict access to your device and demand a fee to be paid to the hacker in order to give you back access to your device. It can prevent you from using your computer or mobile device, opening your files, or running certain applications like your browser. Or it could lock down your photos, documents, videos on your mobile phone or PC and hold them hostage until you pay the ransom.

Users unknowingly download ransomware from malicious by clicking on email attachments or visiting infected websites, also known as drive-by downloads . There are several ways hackers use ransomware to extort money from users. One, the hackers pretend they are a law enforcement agency and claim that you have downloaded illegal content and demand a fine to pay for this violation. Another popular trick is a message that claims your Windows installation is counterfeit and requires activation or that your security software is out of date or not working.

If you download ransomware, you must remove it before you can access your device again. You can use security software or clean out your disk drive. If you have an Android phone, you can reboot your phone in Safe Mode. Whatever you do, don’t pay the ransom, as it doesn’t always guarantee you will get access to your device again.

It’s always better to prepare than repair. Here are a few tips for preventing ransomware from getting on your digital devices.

  • Backup your files. Then, if a ransomware attack occurs, you can wipe your disk drive clean and restore the data from the backup.
  • Think twice. Don’t open links or attachments from people you don’t know.
  • Use a web advisor. Hackers use malicious websites to spread ransomware. A web advisor, like McAfee® SiteAdvisor® will let you know what links are malicious or not.
  • Install comprehensive security software.  McAfee LiveSafe™ service includes a firewall and anti-spam filter to protect your computers, mobile phones and tablets from ransomware. If you already have your computers covered, make sure you still protect your mobile devices with our free McAfee® Mobile Security for Android or iOS.

Have a happy holiday!

Ransomware Attacks Small Businesses

/in , /by

The rate of malware (ransomware) attacks on small businesses climbs at an alarming rate. The security firm McAfee warns that soon, attacks that come through social platforms will be “ubiquitous.” Small businesses are typically not able to subsidize the internal security placements to fend off these attacks, which mostly come from abroad.

6DRansomware blocks your access to data, and the DoS (denial of service) attack threatens to crash your website unless you pay an extortion fee. It’s more organized, it’s more efficient, it’s more automated, it’s more stealthy.

While some businesses give in to DoS extortion demands, others won’t have it. Attacks usually start with relatively small demands, such as $300, to see who’s game. The demands will get pumped up into the thousands quickly once a businessperson pays the initial demand: Pay once, and it’s never over.

If you get a DoS, roll with it; have the extortionist think you need time to prepare payment. Then collect all relevant e-mails and other information for your defense—but not for the police (who lack tech savvy) or the FBI (unless the loss exceeds $5,000), but for your website hosting provider.

The hosting company can collect traffic logs and often can activate DoS defenses or link you to a provider of advanced DoS resolution.

A virus, however, is a different story. Once the virus gets in there and attacks your information, it’s pretty much game over.

Bottom line: Don’t pay the ransom unless you want escalating demands or the strong possibility the extortionist won’t unlock your data after taking your money. A DoS attack will render your site down for days and can permanently lose data and upset visitors.

To avoid a DoS, go anti: virus, spyware, phishing, and use a firewall and run backups. Train your employees well. You have to be conscious of where you’re going and what you’re clicking on.

Ransomware demands Dollars for Data

/in /by

“Ransomware” is what holds data hostage by invading one’s computer when the user clicks on a malicious link in an e-mail or downloads an infected attachment. Visiting a fraudulent web site can also trigger an attack.

CRYRansomware then goes to work at putting your files on lockdown so you can’t access them—but the hacker sure can. The crook will then have full access to your computer and all of your private information stored in it.

Ransomware in some cases masquerades as “Anti-Adware” or “Browser Security” claiming that the security product license has expired. Ransomware on Windows shows as a full-screen “error alert” like message. Though ransomware is uncommon, it’s a rising star in the world of malware.

How can you protect your computer from an infection?

  • Ensure your computer is running the most up-to-date version of your chosen operating system.
  • Use updated antivirus software.
  • Never click links in e-mails. Always go to the source or use your password manager.
  • Never go to unfamiliar web sites, as they can initiate the virus cascade.

Keep in mind that although malware and ransomware usually affect PCs running on Windows, malware can be created for any operating system and for mobiles. In fact, Android malware has been picking up steam. But Mac users should not breathe easy; they too, should be on the alert, says the McAfee Threat Report.

The best way to implement protection of your computer and devices is to install a comprehensive measure of security—in addition to sticking to that never-repeated-too-often rule of never click a link in an e-mail.

What Security Challenges to Focus on in the New Year

/1 Comment/in /by

In 2012, security challenges we faced were often the ribbon cuttings and business plans that startup criminal organizations launched. In 2013, those criminal enterprise business plans will come together—and we need to be ready.

Social media is high on criminal hackers radar. Criminals scan social media looking for people who they can scam. One such scam seeks out entire families and usually targets a grandparent. Criminals will pose as the grandchild and call granny asking for money to be wired. They are also looking at your page to crack password resets. Only friend those you know like and trust and lock down your privacy settings.

With Windows 8 out, criminals have set their sights on this new operating system and are seeking out its vulnerabilities. Old Win XP machines will be as vulnerable as ever. Macs are higher on hackers’ radars, too. Protecting your devices with essential security such as antivirus protection and keeping the OS updated are critical.

Mobile also is high on the hackers’ radar. McAfee predicts that as mobile malware grows, we can expect to see malicious apps that can buy additional apps from an app store without your permission. Buying apps developed by malware authors puts money into their pockets. We also expect to see attacks that can happen without you having to install an app, so no interaction on your part is needed to spread the malicious app.

Mobile ransomware quickly is moving from the PC to mobile devices. Criminals hijack your ability to access data on your phone or even use your phone, so you are faced with losing your contacts, calls, photos, etc. or paying a ransom—and even when you pay the ransom, you don’t always get your data back.

Protect yourself by refraining from clicking links in text messages, emails or unfamiliar web pages displayed on your phone’s browser. Set your mobile phone to lock automatically, and unlock it only when you enter a PIN. Consider investing a service that locates a lost phone, locks it and wipes the data if necessary, as well as restoring that data on a new phone. Keep your phone’s operating system updated with the latest patches, and invest in antivirus protection for your phone.

Internet Security Isn’t Getting Any Prettier

/0 Comments/in /by

Malicious software (malware) is, in many ways, very well understood. Security experts know how it works and why. Cybercriminals’ motivations are pretty straightforward—making money from malware and related attacks.

In the latest McAfee Threats Report: Q3 2012 , malware is still growing and while it’s not growing quite as fast as it was in previous quarters, the amount of malware still topped 100 million samples.

Besides the large growth in mobile malware , there has also been an increase in the tactics that cybercriminals are using to attack you. Some of these techniques include:

Autorun Malware
AutoRun (also known as AutoPlay) is a feature in Windows systems that dictates what action the system should take when a device is connected to your PC. So when you connect your USB drive or insert a DVD into your drive, AutoRun is what will automatically open or in some cases play what is on these devices. Cybercriminals use this feature to automatically install malicious software when an infected USB or other removable device is plugged into your PC. What makes AutoRun scary is it requires no effort on your part to click any links. This is a “plug and play” malware and can even come on products shipped right from the factory such as external hard drives, USB drives and LCD picture frames.

Mac malware
With over 350 new samples in Mac malware in Q3 2012, the growing popularity of Apple products has inspired cybercriminals to create malware that will harm Macs. McAfee Labs is seeing fake antivirus programs targeted at Mac users. In other words, there are an increased number of programs known as “scareware,” which claim to protect users from viruses and malware but users who attempt to install the supposed antivirus software are actually downloading malicious software. This malware can damage your Mac or compromise your personal information.

Ransomware
Ransomware malware typically accuses you of visiting illegal websites, locks your computer then demands a payment to unlock the device. And even if you pay, you are not guaranteed to get access to your files and now the criminal has your financial information.You can get “infected” with ransomware in a myriad of ways, including links in emails, instant messaging, texts and social networking sites, or by simply visiting a website that can download the malicious software on your computer. With a 43% growth this past quarter, ransomware is definitely something to watch out for.

The past quarter’s threats report has shown cybercrime exhibits few signs of slowing down, and cybercriminals using more tricks to steal your money. To help protect yourself you should:

Keep your operating systems updated on all your devices

Be selective about websites you visit and use a safe search tool like McAfee SiteAdvisor® to warn you about risky sites before you click

Avoid clicking links in emails, text messages or instant messages, especially from people you don’t know

Stay educated on the latest tricks, cons and scams designed to fool you

Use comprehensive security software like McAfee All Access that provides cross-device protection for all your PCs, Macs, smartphones and tablets

No Surprise—Ransomware On the Rise

/0 Comments/in /by

McAfee’s latest Threats Report shows a 1.5 million increase in malware since last quarter. 2012 is in fact, far and away the busiest year ever for malware with an estimated total of 100 million malware samples worldwide by Q3 2012.

With the malware growth rate up nearly 100,000 per day, McAfee has identified these key variations of malware affecting everyone, which include, mobile malware, Twitter hackers web threats and specifically ransomware.

Data can sometimes be held hostage with the help of “ransomware,” also known as “ransom software.” This software infiltrates your com­puter when you download an infected attachment or clicking a link within the body of an email. You can also get ransomware simply by visiting the wrong website, in what is called a “drive-by.”

Once your computer or mobile device is infected with ransom­ware, it locks down your files to prevent you from accessing them and gives a hacker full control of your machine. Sometimes the ran­somware poses as a “Browser Security” or “Anti-Adware” security product whose license has expired. Computers running Windows that are infected by ransomware are confronted by a full-screen message that resembles a Windows “error alert”.

Ransomware is not common, but it’s definitely a rising malware threat. The best way to avoid ransomware is to make sure that your computer is running the most current version of your operating system and has updated antivirus software. It’s also very important not to click on links in the body of an email or visit unfamiliar websites that may contain viruses that will attempt to inject them­selves through any security vulnerabilities in your browser.

As PC malware writers master their craft, they are transferring their skills to other popular consumer and business platforms, such as Android devices. After the mobile malware “explosion” in Q1 2012, Android malware shows no signs of slowing down, putting users on high alert.

While malware most typically affects PCs due to Windows software, malware can be written for any operating system and platform. Cautioning all Mac fans they too are susceptible to malware, the McAfee Threat Report notes Mac malware’s steady growth, with more than 100 new samples over Q1 2012.

Users must understand how criminals use psychology with lures of easy money. The most effective way to protect yourself is to install a full suite of security protection on your computer so your money and your information remain guarded.
