Apple devices are extremely popular, which unfortunately makes them a target for theft. To combat this as much as possible, Apple includes features to help users find lost or stolen devices, but these features contain security vulnerabilities of their own. The latest reports, as noted by Loek Essers of TechWorld, center around the “Find My iPhone” feature and a form of ransomware.
When ‘Find My iPhone’ is enabled, users are able to track it to see its current location or lock the device and display a custom message. Users are reporting that their iCloud accounts are being hacked and ‘Find My iPhone’ enabled on their own devices, however. A message informing them that they’ve been hacked by “Oleg Pliss” is displayed and a $100 ransom is demanded.
Users have also reported that while they’re able to log-in to their Apple accounts, they’re unable to disable Lost mode and unlock the device on their own.
At least for some of the victimized users, the problem may stem from the eBay hacking from earlier this month. Some users admit they use the same passwords for their Apple account as they did for eBay.
For now, Apple has been silent on the issue and hasn’t officially suggested a way to unlock hacked devices. The only fix to be found so far is to restore the device to factory settings.
It’s not just iPhones that have been affected either. All Apple device have a similar feature to help find them when they’re lost or stolen and all are vulnerable to this same ransom tactic. So far, users in Australia, Great Britain and Canada have all reported being hacked, but no users from the US have had the same problem.
Before the problem spreads to the US, it’s a good idea to change your passwords, especially if you held an account at eBay that may have been compromised.
If any of your device are hacked, infected with malware, or break, bring them to Geek Rescue or call us at 918-369-4335.

Microsoft’s Silverlight plug-in, which has features similar to Flash and is used for a variety of rich media applications on websites, including Netflix, is leaving users vulnerable to exploits. As Mathew J. Schwartz reports for Dark Reading, outdated versions of Silverlight contain vulnerabilities that lead to malware infections.
Up until recently, vulnerabilities in Silverlight were largely ignored by attackers. In late April, however, a pair of security flaws came to light and drew the attention of a number of exploit kit developers. In many of these attacks, malicious code is hidden in ads displayed by legitimate advertising networks. When these ads are displayed on websites that a user with an outdated version of Silverlight visits, malicious files can be installed.
While these vulnerabilities only exist for users who have failed to keep Silverlight updated, it seems that there’s a large number of users vulnerable and a large number of successful attacks stemming from these flaws. Currently, Silverlight is the most popular target for exploit, according to a report from Cisco.
Part of that popularity stems from the development of exploit kits. These kits are basically attacks in a box that any individual can purchase and launch without the need for any real expertise. These particular Silverlight flaws have made the development of exploit kits fairly simple, which has meant that many are being created at a rapid pace.
Silverlight is the latest, but certainly not the only plug-in that has caused security issues. In 2013, 85-percent of successful attacks involved an exploit of a third-party plug-in like Java or Adobe products like Flash or Reader.
The biggest danger in these plug-in exploits is businesses who are shockingly unprepared for them. Only 29-percent of businesses who were hit with this type of exploit in 2013 were able to discover the breach themselves. In some cases, they were unaware until their client base informed them of a problem.
If you’ve been the victim of an attack and need help clearing the malicious files off your computer and network, or if you’d like to find out more about properly securing your company, call Geek Rescue at 918-369-4335.

Spam is a constant problem for email users and has been since the early days of email. Through spam, malware infections and phishing schemes torment users. Unfortunately, as Malcolm James reports for the All Spammed Up blog, the spam problem in the US is getting worse.
A report released by antivirus manufacturer Kaspersky that users in the United States receive more malicious emails than any other country. At nearly 14-percent of the world’s spam, the US leads this category by almost a full 4-percent over second place United Kingdom.
Over the past few months, the US has seen a sharp increase in spam emails. In the third quarter of 2013, US email users received about 10-percent of all spam, while users in the UK received the most at about 12-percent.
One noticeable trend is an increase in spam targeting mobile users. Most notably, spammers have begun sending messages that appear to be from popular mobile app developers. Messaging app ‘WhatsApp’ has been used in a number of email scams to spread malware. Even users who have never connected an app to their email address have been fooled. For many users, these messages are believable enough that they’re opened and an attachment downloaded to investigate further. Unfortunately, that’s all the action a user needs to take for malware to infect their system.
Overall, about two-thirds of all email messages are categorized as spam. This is actually down from the end of 2013, but about the same as this time last year. Experts warn that the total amount of spam is less consequential than the tactics the spammers are using. New, more intelligent tactics are allowing more spam to slip through filters and find their way into users’ inboxes, which creates more opportunities for users to mistakenly open these messages.

A typical internet user has too many online accounts to manage a unique, strong password for each one. While passwords are still the primary form of security for many important online accounts, being able to realistically keep track of a different password for all of them, which is recommended, is nearly impossible. Ian Barker of Beta News published some tips on how to keep up with passwords when there are seemingly too many to manage.
A recent survey revealed that more than half of internet users have more than 20 active online, password protected accounts. Another 27-percent have between 11 and 20 online accounts. Can you keep 20 different passwords of varying length and using numbers, letters and symbols straight? For that matter, can you keep 11?
For most of us, the answer is a resounding ‘no’. This leads to bad habits. Reusing passwords is common. Using easy to guess passwords is too. This leads to accounts being compromised, which leads to identity theft and other serious problems.
One answer is to use a password manager. There are plenty of trustworthy managers available that will store all of your passwords behind one master password. Many managers even log you in automatically to your accounts. Less than half of internet users are using password managers, however.
The other option, and one that is much more realistic than keeping track of dozens of different passwords for different accounts, is to identify which accounts hold the most valuable information. Banking and credit card sites are obvious choices for your strongest passwords. Don’t overlook ecommerce sites that have your credit card information, address and other personal information stored on them. Also, consider how costly it would be for a criminal to gain access to your social media accounts. Finally, your primary email address, which likely is the destination for password reset messages from other accounts, is vital to protect properly.
Each of these accounts demands a long, strong, unique password to minimize the risk of it being hacked. Some, like email and social media, can even use two-factor authentication to up the security ante even more.
Other accounts, however, don’t need as much attention. An account for a message board, news site or other site where a username and password are the only information at risk don’t necessarily need strong, unique passwords. If these accounts are hacked, you won’t lose much.
For many users, concentrating solely on their most valuable online accounts limits the amount of important passwords to less than ten, which is much easier to manage.

One major challenge businesses face in maintaining effective security is the trend of employees using their own devices for work. ‘Bring your own device’, or BYOD, refers to employees using any of their personal devices on your network. At the very least, your employees are likely using their smartphones. There are a number of reasons why this complicates things from an IT standpoint, but at IS Decisions, Francois Amigorena explains some ways to improve security in a BYOD environment.
A vital move to securing your network while employees are using multiple devices to access it is to prevent concurrent logins. Each employee is given specific credentials and are unable to log in with those credentials if they’re being used on another device. This potentially creates some issues with employees being logged in on their desktop and being unable to gain access remotely, but it also prevents lost or stolen device from being able to access the network freely.
In conjunction with login limitations, it’s important to implement time limits for employees’ active sessions. After a set time, the device would automatically prompt users to log in again using their credentials. This protects against the possibility of a logged in device being compromised.
Regardless of the device they’re using to access your network, most employees don’t need access to everything available on the network. It takes meticulous planning, but limiting what files and applications each user is able to access greatly increases security by reducing the potential for complete disaster. Even if a third party gains access through a lost device, they won’t be able to control your entire network.
If employees are regularly using your network with multiple devices, it’s important to keep a running log of those devices. This way, if an employees access requirements change, you can quickly change their permissions for all applicable devices. Likewise, should an employee leave the company, you can quickly end access for their devices to keep them from taking valuable data with them.
It’s important to always closely monitor the activity on your network, but this becomes more important when users are potentially bringing in threats on their own devices. Log in attempts from unrecognized devices, or log ins at odd hours, or sessions moving large amounts of data should all trigger flags. This will allow you to minimize damage.
BYOD is only one challenge that business owners face every day regarding their network’s security.

It’s a well-known concern that Android users are much more at risk for malware infections than iOS users. Just a month ago, a fake antivirus app made the rounds in the official Google Play store and victimized a number of users. Google has since offered refunds to those who mistakenly downloaded the malicious app, but it seems they haven’t sufficiently protected against a similar threat reappearing. Lucian Constantin reports at Network World that the Google Play store and the app store for Windows Phones have both recently had malware hidden behind recognizable brand names identified in their stores.
It’s a fairly recent development, but it seems criminal developers are launching malicious apps with well-known company names to further confuse users. This is a well-known tactic of email scams and phishing websites.
One developer account launched malicous apps under the names Avira Antivirus, Mozilla Firefox, Google Chrome, Opera Mobile, Internet Explorer and Safari. The same developer also has a Kaspersky Mobile antivirus app complete with the company’s logo. When downloaded, the app will even simulate a scan of the device’s files.
Making these fake apps more believable, and more costly to users, is that they aren’t free. The Kaspersky Mobile app costs about $4. Most users instinctively trust paid apps more than free ones. A number of free apps have been reported to be malicious, but there’s an implied value tied to something that costs money. It’s also much more believable to pay money for a high quality, big name security app than to get it for nothing.
Some of these apps have been downloaded more than 10-thousand times and even made it onto the “Top Paid” apps list that helps them be further distributed.
Because there has been no sufficient changes made to the Android and Windows Phone app stores, it’s likely that these fake apps will continue to pop-up. However, since many of them steal the exact name of legitimate apps from recognized industry leaders, there’s also likely to be more pressure put on both Google and Microsoft to enhance security.
If you’ve mistakenly downloaded a malicious app, or are having any other kind of trouble with one of your devices, call Geek Rescue at 918-369-4335.

We’ve discussed before how data breaches lead to a loss in revenue for businesses. That’s not the only issues that stem from an exploit in a security vulnerability, however. At Dark Reading, Tim Wilson reports on a recent survey conducted by the Ponemon Institute that reveals how consumers react to a company’s data being compromised.
When it comes to a brand’s reputation, which influences how likely a consumer is to do business with that brand, there are three leading factors that have the greatest negative impact. Those factors are poor customer service, environmental disasters, like oil spills, and data breaches. That these are the most influential may not be that surprising until you realize what they beat out. Other factors that finished lower in the survey were publicized lawsuits, government fines and labor or union disputes.
It’s not surprising why consumers feel so strongly about avoiding businesses who have experienced a data breach. About a quarter of typical consumers are extremely concerned about being the victim of identity theft. That jumps to about half of consumers who are customers of a company who has experienced a data breach and many of those believe their identity and personal information will be at risk for years to come, or even for the rest of their lives. For these individuals, it’s better to sever ties with a company they’ve done business with for years than to risk their information falling into the wrong hands.
This report contains a clear message for businesses. A loss of customers is inevitable should you suffer an attack that results in the theft or exposure of important data. That’s why it’s important to invest in security now before a successful, and costly, attack occurs. The reality is that many small to medium businesses fail to ever recover from a severe attack. A lacking security infrastructure could actually lead to the loss of a business.

It’s important to have proper security tools in place to protect your computer from attacks and malware. Tools like antivirus programs, firewalls and router security are essential. If you’re a Windows 8 user, you’ve even got some handy built-in security features to assist. At Window Security, Ricky and Monique Magalhaes list the various security features you’ll enjoy with any version of the Windows 8 operating system.
You may not ever notice, but Windows 8 has made a concentrated effort to improve the security associated with wireless internet connections. By extending support to Mobile Extensible Authentication Protocol standards they’ve done just that and made it easier to connect to secure networks.
There are a few different scenarios where you’d need to remotely remove data from your device. If a device is lost or stolen, or if your company allows employees to bring their own device and you need to remove data after an employee has left the organization are just a couple. Windows 8 includes a remote data removal feature to help protect both users and administrators.
Windows 8 offers Unified Extensible Firmware Interface, or UEFI, which probably doesn’t mean much to you. It’s an interface between the operating system and the firmware that’s a significant upgrade in security over previous operating systems. When attackers gain access to and manipulate the firmware, it’s extremely bad for the user. UEFI keeps this from happening.
Windows Defender comes with Windows 8 and while that isn’t a new feature, it does have enhanced performance and decreased memory usage. While Defender and other features of Microsoft Security Essentials are useful, they’ve never been meant as stand alone security solutions. Using them in addition to other antivirus and anti-malware programs creates a more secure environment.
Improved and added security features in Windows 8 aren’t limited to what’s listed here. Microsoft clearly concentrated on improving security for their users with the latest version of their operating system, but that doesn’t mean that using Windows 8 security features alone will keep you safe from malware. These features are only a part of an effective security infrastructure.

The hard truth is that it’s extremely difficult to effectively secure a business from cyber attacks, malware and data breaches. It’s also vital to managing a successful business, however. At Dark Reading, Mark Goldstein and Arun Sood published a list of common security myths that hinder both the understanding and the effectiveness of a company’s security infrastructure.
What is adequate in the context of data security? The truth is that no system is 100-percent effective. Successful attacks are unavoidable because it’s impossible to secure every endpoint while simultaneously dealing with thousands of new pieces of malware each day. The key is to minimize the risk and the damage and have a plan in place to recover and mitigate attacks.
Many business owners believe that server and security management is as simple as getting everything online, then dealing with problems as they arise. That’s one way, but that introduces a number of potential problems. First, by not being proactive and looking ahead for issues that could happen in the future, you’re actually likely to have more problems and more downtime. Similarly, while static systems cost less and require fewer man hours, they also create an unchanging target for attackers.
- All Threats Demand Action
Common sense suggests that any time there’s an intrusion or a vulnerability, your IT team needs to take action. In reality, however, reacting the same to every threat only means that you’re unable to react sufficiently to the most dire of threats. IT professionals understand that there are minor attacks that can’t do any real damage. It’s unwise for these threats to trigger the same alarms as large scale attacks because it increases the chances that one of these serious threats gets missed or overlooked.
- Patch All Vulnerabilities
In the same vein, don’t expect to be able to patch and close all security vulnerabilities that exist on your network. New vulnerabilities are added every day, or even every hour. With tens of thousands of vulnerabilities, it’s impossible and a waste of time to try to secure each of them. Instead, good IT professionals know how to spot the most dangerous vulnerabilities and patch them immediately. This is a more efficient use of time and keeps the most dangerous threats out while protecting your most valuable assets.

You may already know that effectively implementing security into your IT infrastructure is a vital step towards protecting your business, but unfortunately you likely aren’t working with a limitless budget. Anyone can secure their business with an endless flow of cash, but it becomes much more difficult when you’re having to decide what’s worth the money and what isn’t. At Network World, George V. Hulme gives some tips for how best to use your security budget to get the most out of your investment.
As time marches on, you’re business will need new security tools. This is either because the tools you had in place are no longer effective against current threats, or because your infrastructure has changed enough to warrant a change in security. When that happens, adding new tools is great, but decommissioning the now obsolete tools is just as important. Too many business owners have no process for removing security applications from their infrastructure when they’re no longer needed. Many aren’t able to recognize which tools have become redundant and won’t hurt to be decommissioned. Trimming out these old security tools also trims the budget.
All of that said, before you invest in a new application or new equipment, be sure you actually need it and will be able to effectively use it. A chief security officer suggests asking yourself three questions:
Are their people on staff who know how to use this?
Do they have the time to install, use, maintain and manage it?
Will it have an effect?
Investing in new technology that won’t benefit your business is obviously foolish. But, many don’t recognize that even technology that will positively affect their business shouldn’t be implemented without the proper staff in place.
When it comes to effectively staffing your IT department, you aren’t always saving money when you think you are. Many business owners believe they can cut corners and staff fewer professionals in order to save money. But, this often leads to more downtime and less security in place, which can lead to successful attacks, malware infections and data theft. All of these cost you money and productivity. There’s likely to be a shortage of qualified IT professionals in the coming years so investing in IT now can save you from being dangerously under-staffed later.
Properly using your IT budget can be difficult. At Geek Rescue, we provide IT solutions for businesses on any scale. Our clients receive the benefit of an entire IT staff without having to deal with the headaches of actually hiring and maintaining an IT department.
