Ransomware Attackers Are Increasing Their Attacks On Businesses

December 21, 2017 by Joseph Martin

The ransomware ecosystem is maturing. Strains are divided into “families” and the number of new families that have been discovered in 2017 is half what it was in 2016. Even so, the total number of attacks targeting businesses have risen by 26 percent over last year’s totals, according to the latest statistics released by Kaspersky Lab.

Rather than inventing wholly new software strains, hackers around the world seem content to modify existing strains, with the number of modifications growing from 54,000 to an astonishing 96,000 this year.

The modifications are having impacts that extend far beyond simply allowing them to slip past a company’s defenses. Last year, 29 percent of companies impacted by a ransomware attack claimed that the incident took a week or longer to recover from. This year, that percentage rose to 34 percent.

According to one of Kaspersky’s senior malware analysts, Fedor Sinitsyn, “The headline attacks of 2017 are an extreme example of growing criminal interest in a corporate target. We spotted this trend in 2016, it has accelerated throughout 2017 and shows no signs of slowing down.

Business victims are remarkably vulnerable, can be charged a higher ransom than individuals and are often willing to pay up in order to keep the business operational. New business-focused infection vectors, such as through remote desktop systems, are not surprisingly on the rise.”

In addition to the total number of such attacks increasing, we’ve seen several large-scale attacks this year, and there’s no reason to believe that we won’t see more of that in the months and years ahead.

This represents a fundamental shift in strategy as compared to years past and is a clear indication that hacking groups around the world are increasingly coordinating their efforts and learning from one another. That’s bad news for IT security professionals everywhere.

Paypal-Owned Company Sees Breach Of 1.6 Million Customers

December 20, 2017 by Joseph Martin

TIO Networks, a cloud-based, multi-channel bill payment platform purchased by Paypal for $233 million in 2017, was breached earlier this year, exposing PII (Personally Identifiable Information) for an estimated 1.6 million of the service’s users.

TIO Networks primarily does payment processing and accounts receivables for cable, utility, wireless and telecom companies in North America. If you do business with TIO, it’s possible that your company or personal information may have been compromised.

So far, neither Paypal nor TIO Networks has released any significant details about the breach, so we do not yet have any indication of how it happened, who was responsible or exactly which of their customers had their information exposed. Paypal did release a brief statement concerning the incident, which said, in part:

“The PayPal platform is not impacted in any way, as the TIO systems are completely separate from the PayPal network, and PayPal’s customers’ data remains secure.”

The statement went on to say that as soon as PayPal identified the breach, they took action by “initiating an internal investigation of TIO and bringing in additional third-party cybersecurity expertise to review TIO’s bill payment platform.”

For their part, TIO Networks has suspended all operations until the investigation into the matter has been completed, and has begun notifying impacted customers. In addition to that, as is common with situations like these, they’re also working with Experian to provide a year’s worth of free credit monitoring for people who were affected.

A part of TIO’s statement about the incident reads as follows: “At this point, TIO cannot provide a timeline for restoring bill pay services, and continues to recommend that you contact your biller to identify alternative ways to pay your bills….We sincerely apologize for any inconvenience caused to you by the disruption of TIO’s service.”

Former Employees Pose Serious Risk To Security

December 19, 2017 by Joseph Martin

The Department of Health and Human Services’ Office for Civil Rights (OCR) has reminded those who deal with PHI and PII of the dangers that terminated employees can pose to system security in their monthly cyber security newsletter. Their advice is as timely as it is excellent, and includes the following:

“Making sure that user accounts are terminated so that former workforce members don’t have access to data is one important way Identity and Access Management can help reduce risks posed by insider threats.

IAM can include many processes, but most commonly would include the processes by which appropriate access to data is granted, and eventually terminated, by creating and managing user accounts.”

Kate Borten, President of The Marblehead Group, agrees, citing Verizon’s 2017 Data Breach Investigations Report, which was released earlier this year and named health care as the industry with the highest number of insider breaches.

OCR has published an extensive list of recommendations, which include:

• The creation and maintenance of user access logs used to determine when a user’s access levels are increased, or new equipment is assigned. These logs can also be used to track and trace precisely who is accessing what data, when, and using what locations, creating an audit trail.

• Establishing processes designed to terminate an employee’s access as soon as employment ends. These processes should also refer back to the aforementioned access logs to ensure that all equipment has been returned.

• Changing all administrative passwords on termination of an employee with access to those accounts, so that they will be unable to access them post-employment.

• The creation of alerts that call attention to accounts that have not been utilized in some predefined number of days in order to identify accounts that may be ripe for purging from the system.

• And developing a robust auditing procedure designed to ensure that all IAM-related policies are being followed and that the system is working as intended.

It’s an excellent piece, and if your firm is in any way involved with the handling of protected health information, you owe it to yourself to head to OCR’s website and read it in its entirety.

How Fast Can You Be “Backup” And Running?

December 18, 2017 by Joseph Martin

Data Disaster Averted

Having appropriate data backup solutions isn’t the only concern when it comes to an IT disaster for your business. Depending on what your method of data recovery is, in the event of a data loss event, you could be putting your business on hold as you put the pieces back together.

Not all Data Recover is Created Equal

While there are multiple methods for data backup solutions, they aren’t all a safe choice. While hard copy backup solutions such as flash drives and servers are great for recovering from minor disaster events, they don’t save you in the event of a fire, burglary or a server crash. This brings about the importance of having an offsite solution such as a cloud system that can be accessed even when your physical office cannot be.

The Data Backup Delay

The other primary challenge of ensuring you have a proper disaster recovery plan in place is business continuity. Having data backup services in place aren’t enough, you also have to take into account the time needed to get things back up and running again. When using in-house servers and flash drives to backup files, you automatically put yourself at risk for a long reboot process. Files, software and documents must be uploaded from these devices and this could take hours or even days. This results in lost work time and money. Having an off-site backup system, such as cloud services, allows employees to be able to continue their work from home, even if the office and its servers are not accessible. This also eliminates any lost time in your services or project work.

Many Consumers Would Withdraw Business From Companies If Data Breached

December 17, 2017 by Joseph Martin

You’ve probably heard the phrase “the customer is always right” a thousand times. It’s a truism in the business world, except when it isn’t. A recent survey released by Gemalto reveals a dismaying dichotomy that’s costing businesses around the world big money.

Only 27 percent of consumers surveyed feel that businesses do enough to protect customer data, and an overwhelming 70 percent of them say that they’d take their business elsewhere if a company suffered a data breach.

Unfortunately, most consumers have exceedingly poor data security habits, with 56 percent admitting to using the same password across multiple web properties and 41 percent failing to take advantage of stronger security measures like two-factor authentication, even when offered by companies.

That puts businesses, rather unfairly, in the crosshairs. They cannot make their customers take advantage of the added security offered, and given the statistics above, they are forced to have to spend even more money since most consumers won’t take significant action to protect themselves or their own data.

Jason Hart, Gemalto’s CTO, had this to say on the matter:

“In the face of upcoming data regulations such as GDPR, it’s now up to businesses to ensure they are forcing security protocols on their customers to keep data secure. It’s no longer enough to offer these solutions as an option. These protocols must be mandatory from the start – otherwise, businesses will face not only financial consequences but also potential legal action from consumers.”

Digging more deeply into the details of the survey, we find that consumers trust social media sites the least when it comes to safeguarding their data, with 58 percent of respondents citing these companies as their biggest worry in terms of data security.

Curiously, 33 percent of those surveyed say they trust banks with their personal data, in spite of the fact that banks and other financial institutions are frequent targets and have suffered a number of high profile breaches in recent years.

Regardless, no matter what industry you’re in, if you get breached, your customers are likely to punish you for it, even if you offer them means to make their data more secure.

Windows 10 Now Installed On Over 600M Machines

December 16, 2017 by Joseph Martin

When Microsoft first released Windows 10, the company boasted that it would try to get its new OS running on a billion devices by 2018.

Time and circumstance have conspired to make that lofty goal unlikely, and the company has since retreated from it. However, according to statistics released at a recent shareholder’s meeting, there are now more than 600 million devices utilizing it, including PCs, tablets, HoloLens headsets, Surface Hubs and Xbox One consoles.

It’s an impressive number, but two things contributed to dramatically slowing the overall rate of adoption.

First and foremost, the company recently ended its free Windows 10 upgrade offer, which had been the driving force behind the rapid adoption since the initial release of the OS. Secondly, Microsoft gave up on the Windows Phone, making it unlikely in the extreme that smartphones will ever contribute in any significant way to the total number of installed devices.

Earlier this year, Microsoft found itself in hot water when it was discovered that the company was quietly pushing the new OS onto Windows 7 and Windows 8 machines. This move ate up a whopping six gigabytes of hard disk space and drew a considerable amount of fire from a variety of user and industry groups.

Some of the other tactics used by the company have also been found to be overly aggressive, and in some cases, downright coercive. The worst of these have since been abandoned, but not before considerable damage had been done to the company’s image.

As things stand now, Windows 10 is the second most widely used desktop OS, behind only Windows 7, which has a market share of 52.37 percent according to the latest statistics by Netmarketshare. Even if Microsoft never quite reaches its initial 1 billion-device goal, 600 million devices are nothing to sneeze at.

Look And Feel May Change In Future Windows 10 Update

December 15, 2017 by Joseph Martin

Microsoft is experimenting with a new feature that may change the look and feel of Windows 10 in some future update.

The new approach is referred to as “Sets,” which borrows from the playbook of modern web browsers and groups related applications into tabbed sets, with the groupings defined by project type. The applications you need to make use of on any given project will be grouped together, even if the last time you used a given app was several weeks prior.

Essentially, this approach is a combination of the Windows Explorer “Task View,” “Pick up where you left off” and “timeline.” They are wrapped into a single-window experience complete with an “application history” feature, which works a lot like a web browser’s history, so you won’t have to remember which application you were using a few weeks earlier to work on your current project.

It’s a good idea in theory, and it should streamline the user experience. If, for example, you need to use your email, Microsoft Word, Photoshop and Excel to complete a given project, all of these will be organized as tabs across a single window.

While there’s been no word from Microsoft on exactly when we can expect to see the new feature, if the past is any guide, it will first be available to Windows Insiders for an initial evaluation. In the meantime, Microsoft will be seeking support for the new concept from a wide range of third party developers.

Another clear sign that the company is committed to the new idea is that Stardock, a company which has provided some intriguing UI tweaks to Windows for several years now, has released a new product called “Groupy,” which reproduces some of the basic features planned for Sets.

So far, Microsoft hasn’t released a firm time table, so there’s no clear indication when we might be seeing the change. We’ll have more information on this topic as it becomes available.

Fake Symantec Blog Post Is Spreading Mac Malware

December 14, 2017 by Joseph Martin

Sometimes hackers opt for a stealthy approach. Other times, their attempts are downright brazen. That’s definitely the case with a newly launched malware campaign that seeks to spread “Proton Mac,” a strain of malware designed to steal passwords from Mac users.

The hackers registered a domain very similar to Symantec’s blog, mirrored its content and then created a fake post about a new version of CoinThief, which was moderately successful back in 2014.

After going into a bit of faux analysis about this nonexistent threat, the post recommended downloading a nonexistent piece of software called “Symantec Malware Detector” which it claimed was the best means of protecting against the new version of CoinThief. Unfortunately, “Symantec Malware Detector” is actually Proton Mac in disguise.

It’s a good scam, and it’s proven to be highly effective thus far. Its effectiveness is due in no small part to the fact that references to the post have been tweeted, initially by fake Twitter accounts, and later, by a growing number of legitimate ones.

Although the fake blog is quite good, it doesn’t stand up to intense scrutiny. For one thing, the email address used to register the domain isn’t a Symantec address. For another, their SSL certificate comes from Comodo, rather than Symantec’s own certificate authority. Unfortunately, the overwhelming majority of users don’t look that closely at websites they visit, so they are unlikely to recognize the fake for what it is.

If you have downloaded “Symantec Malware Detector,’ then you’ve got Proton Mac running on your machine right now.

It’s designed to log your username and password in plain text, sending this and any other PII (Personally Identifiable Information) on your machine to a hidden file. It will also capture browser auto-fill data, keychain files and the like, and send all of this to the hackers controlling the software.

If you have been infected, you should treat all online passwords as having been compromised and change them immediately, once you have verified that the malware has been completely removed from your system. Enabling two-factor authentication will also help make you more secure.

Bug in macOS Could Allow Hackers Root Access

December 13, 2017 by Joseph Martin

Do you own a Mac? Is it running Apple’s latest macOS, the “High Sierra?” If so, be extra careful with who you allow access to your machine.

A security flaw recently discovered by a developer named Lemi Orhan Ergin can easily allow anyone unfettered access to everything on your machine, and by extension, give them an easy “in” to whatever network it’s connected to. All they need is physical access.

Exploiting this vulnerability is a lesson in simplicity. All a hacker has to do is enter “root” in the username field, leave the password field blank, and press Enter.

Done.

They now have total access.

Needless to say, this is a large and rather glaring security issue and one which Apple will be remedying in the near future via a patch. Until they do, however, be aware that the physical security of your Mac is of paramount importance. Leaving your workstation unsecured and unattended, even for a few minutes, is all it would take to lose control over all the files on your machine and give a hacker access to the even more sensitive data lurking elsewhere on your company’s network.

Unfortunately, as bad as this security flaw is, it’s not the only recent stumble by Apple. Just last month, the company had to issue an emergency patch to fix a flaw that affected encrypted volumes, where the password hint section was displaying the actual password in plain text.

To try this exploit out for yourself to verify how easy it is to use, simply do the following:

Open your machine’s System Preferences and select “Users and Groups”

Click on the lock icon, which will allow you to make changes. You’ll get a username and password box at this point

Type in “root” in the username field

Move the cursor into the password field and hit enter

That’s all there is to it.

Until Apple issues their patch, the best thing you can do is leave your machine on and lock your workstation when you step away. At least that way, the hacker would have to know your current password in order to gain access.

Of course, they could simply power the machine off and reboot, but that would take a bit more time, during which they could be discovered.

It’s far from perfect, but for the time being, it’s the best protection you have.

A Million Imgur Users Affected By Breach

December 12, 2017 by Joseph Martin

Do you use the image hosting service, Imgur? If you do, there’s a slight chance that you’ll be prompted to change your password the next time you log on. That’s because the company’s servers were breached in 2014, and the hackers made off with 1.7 million usernames and passwords, which represents just a tiny fraction of the company’s 150 million users.

Although the breach happened a few years ago, the company only found out about it on Thanksgiving Day of this year. Their response was immediate and decisive. The company called people in over the holiday and notified their impacted users just 25 hours and 10 minutes after discovering the details of the incident.

Contrast that to Uber’s handling of their most recent hack. They kept their impacted users in the dark for more than a year, and worse, paid the hackers $100,000 to keep the incident quiet. It’s easy to see why security professionals around the world have lauded Imgur for their handling of the hack.

Three key things to note in relation to the breach:

Not much information was stolen during the hack because Imgur doesn’t ask its users for much in the way of personal information in the first place. However, if you use your Imgur password on other systems, you could be at additional risk.

At the time of the breach, Imgur was using SHA-256 encryption, which is fairly robust and impractical for most hackers to crack due to the amount of computational power required.

In 2015, the company switched to an even more secure algorithm, Bcrypt, so if the company is breached again in the future, it’ll be even harder for the hackers to glean anything useful from any data stolen.

All that to say, if you’re looking for a benchmark to compare yourself to if you’re ever hacked, Imgur’s example would be an excellent one to follow.
