Meltdown and Spectre still continue to dominate the security news and the more we delve into it, we are starting to understand the depth and breadth of what this now means for the future of the security landscape.
Turns out the three variants of side-channel attacks, Meltdown and two different for Spectre, were discovered back in June of last year  by researchers using speculative execution, which is where processors execute on code and then fetch and store the speculative results in cache. It’s a technique used to optimize and improve the performance of a device. What is important to note with Spectre is that it puts users at risk for information disclosure by exposing the weakness in the architecture of most processors in the market, and the breadth is vast: Intel, AMD, ARM, IBM (Power, Mainframe Z series) and Fujitsu/Oracle SPARC implementations across PCs, physical and virtual servers, smartphones, tablets, networking equipment and possibly IoT devices.
Currently there are no reported exploits in the wild.
Of the two, Meltdown is the easier one to mitigate with operating system updates. AMD processors are not affected by Meltdown. Spectre is a bit more complex to resolve because it is a new class of attack. The two variants of Spectre both can potentially do harm like stealing logins and other user data residing on the affected device. Intel, ARM, and AMD processors are affected by Spectre. Recently, Microsoft released another emergency update to disable Intel’s microcode fix. This original update was meant to patch for variant 2 of Spectre. Unfortunately, that update had adverse effects as there were numerous reports of reboots and instability, so Microsoft issued an out of band update to disable.
Things are still evolving around Spectre and while operating system updates and browser updates are helping to patch for Spectre, it is being reported by some sources that a true fix may be an update to the hardware (processor) itself.
The following is a chart* to clarify each vulnerability:

It will be important over the next few weeks to stay on top of any breaking news around Meltdown and Spectre. Mitigation efforts should be underway in your IT organization to prevent a future zero-day attack.

Earlier this month, CES attendees got a taste of the future with dazzling displays of toy robots, smart assistants, and various AI/VR/8K gadgetry. But amid all the remarkable tech innovations on the horizon, one thing is left off the menu: user privacy. As we anticipate the rocky road ahead, there are three major pitfalls that have privacy experts concerned.
Biometric authentication—using traits like fingerprints, iris, and voice to unlock devices—will prove to be a significant threat to user privacy in 2018 and beyond. From a user’s perspective, this technology streamlines the authentication process. Convenience, after all, is the primary commodity exchanged for privacy.
“Imagine a scenario where an attacker gains access to a database containing biometric data,” said Webroot Sr. Advanced Threat Research Analyst Eric Klonowski. “That attacker can then potentially replay the attack against a variety of other authenticators.”
That’s not to say that biometrics are dead on arrival. Privacy enthusiasts can find solace in using biometrics in situations such as a two-factor authentication supplement. And forward-thinking efforts within the tech industry, such as partnerships forged by the FIDO Alliance, can help cement authentication standards that truly protect users. For the foreseeable future, however, this new tech has the potential to introduce privacy risks, particularly when it comes to safely storing biometric data.
Big data, big breaches
2017 was kind of a big year for data breaches. Equifax, of course, reined king by exposing the personal information (including Social Security Numbers) of some 140 million people in a spectacular display of shear incompetence. The Equifax breach was so massive that it overshadowed other big-data breaches from the likes of Whole Foods, Uber, and the Republican National Committee.
It seems no one—including the government agencies we trust to guard against the most dangerous online threats—was spared the wrath of serious data leaks. Unfortunately, there is no easy remedy in sight, and the ongoing global invasion of user privacy is forcing new regulatory oversight, such as the upcoming GDPR to protect EU citizens. The accelerated growth of technology, while connecting our world in ways never thought possible, has also completely upended traditional notions surrounding privacy.
The third big issue that will continue to impact privacy across the board is the current lack of young talent in the cybersecurity industry. This shortfall is a real and present danger. According to a report by Frost & Sullivan, the information security workforce will face a worldwide talent shortage of 1.5 million by 2020.
Some of this shortfall is partly to blame on HR teams that fail to fully understand what they need to look for when assessing job candidates. The reality is that the field as a whole is still relatively new and is constantly evolving. Cybersecurity leaders looking to build out diverse teams are wise to search beyond the traditional background in computer science. Webroot Vice President and CISO Gary Hayslip explained that a computer science degree is not something on his radar when recruiting top talent for his teams.
“In cyber today, it’s about having the drive to continually educate yourself on the field, technologies, threats and innovations,” said Hayslip. “It’s about being able to work in teams, manage the resources given to you, and think proactively to protect your organization and reduce the risk exposure to business operations.
Beyond shoring up recruiting practices for information security roles, organizations of all types should consider other tactics, such as providing continual education opportunities, advocating in local and online communities, and inevitably replacing some of that human talent with automation.

From Facebook to LinkedIn, social media is flat-out rife with phishing attacks. You’ve probably encountered one before… Do fake Oakley sunglasses sales ring a bell?
Phishing attacks attempt to steal your most private information, posing major risks to your online safety. It’s more pressing than ever to have a trained eye to spot and avoid even the most cunning phishing attacks on social media.
Facebook has warned of cybercriminals targeting personal accounts in order to steal information that can be used to launch more effective spear phishing attacks. The social network is taking steps to protect users’ accounts from hostile data collection, including more customizable security and privacy features such as two-factor authentication. Facebook has also been more active in encouraging users to adopt these enhanced security features, as seen in the in-app message below.
Types of social phishing attacks
Fake customer support accounts
The rise of social media has changed the way customers seek support from brands, with many people turning to Twitter or Facebook over traditional customer support channels. Scammers are taking advantage of this by impersonating the support accounts of major brands such as Amazon, PayPal, and Samsung. This tactic, dubbed ‘angler phishing’ for its deepened deception, is rather prevalent. A 2016 study by Proofpoint found that 19% of social media accountsappearing to represent top brands were fake.
To avoid angler phishing, watch out for slight misspellings or variations in account handles. For example, the Twitter handle @Amazon_Help might be used to impersonate the real support account @AmazonHelp. Also, the blue checkmark badges next to account names on Twitter, Facebook, and Instagram let you know those accounts are verified as being authentic.
Trending content such as Facebook Live streams are often plagued with spammy comments from accounts that are typically part of an intricate botnet. These spam comments contain URLs that link to phishing sites that try to trick you into entering your personal information, such as a username and password to an online account.
It is best to avoid clicking any links on social media from accounts you are unfamiliar with or otherwise can’t trust. You can also take advantage of security software features such as real-time anti-phishing to automatically block fake sites if you accidently visit them.
Yes, phishing happens within Direct Messages, too. This is often seen from the accounts of friends or family that might be compromised. Hacked social media accounts can be used to send phishing links through direct messages, gaming trust and familiarity to fool you. These phishing attacks trick you into visiting malicious websites or downloading file attachments.
For example, a friend’s Twitter account that has been compromised might send you a direct message with a fake link to connect with them on LinkedIn. This link could direct to a phishing site like the one below in order to trick you into giving up your LinkedIn login.
While this site may appear to look like the real LinkedIn sign-on page, the site URL in the browser address bar reveals it is indeed a fake phishing site.
Phony promotions & contests
Fraudsters are also known to impersonate brands on social media in order to advertise nonexistent promotions. Oftentimes, these phishing attacks will coerce victims into giving up their private information in order to redeem some type of discount or enter a contest. Know the common signs of these scams such as low follower counts, poor grammar and spelling, or a form asking you to give up personal information or make a purchase.
The best way to make sure you are interacting with a brand’s official page on social media is to navigate to their social pages directly from the company’s website. This way you can verify the account is legitimate and you can follow the page from there.

There’s no end to ransomware in sight. It’s a simple enough attack — install malware, encrypt data/system, and ask for the ransom — so why aren’t we stopping ransomware? Security vendors are keenly aware of the issue, as well as the attack vectors and methods, but can’t seem to stay a step ahead, causing ransomware to grow form $1 billion in damages in 2016 to an estimated $5 billion in 2017. There are two basic reasons ransomware continues to be a “success” for cyber criminals.
Reason 1: Malware authors are getting better at their craft
Just when we think we’re getting on top of the ransomware problem, our adversaries alter their tactics or produce new techniques to replicate and cause damage and misery. We’ve recently seen ransomware like WannaCry take advantage of unpatched vulnerabilities in the Windows SMB service to propagate around networks, especially those that had SMB open to the internet — A clever technique borrowed from mid-to-late 90s Windows worm malware like Sasser. We’ve also seen malware writers develop new techniques for installing malicious code onto computers via Microsoft Office. While the threat posed by malicious macros in Office documents has existed for a number of years, we’re now seeing the use of a Microsoft protocol called Dynamic Data Exchange (DDE) to run malicious code. Unlike macro-based attacks, the DDE attack doesn’t give the user a pop-up, prompt or warning, so exploitation is far more effective and successful.
The technological advances made by malware authors are significant, but their soft skills, like social engineering, also keep on getting better. Improved writing, more realistic email presentation, and even solid social engineering tactics are all cause for the increase in their success.
And if you’re good at what you do, make it a service and profit on those that have a similar interest, but lack your skills. Thus, “crime-as-a-service” and “malware-as-a-service” now exist, further perpetuating the ransomware problem. The availability and ease of use of these platforms, means anyone can turn to cybercrime and ransomware with little or no coding or malware experience. These platforms and networks are run by organized cybercrime gangs, for vast profits, so we won’t see them going away any time soon,
Reason 2: We’re causing our own problems
Of course, there’s still one large problem many of us have not dealt with yet, and that’s the weaknesses we ourselves cause that become the entry way for the cybercriminals. WannaCry was so successful because it leveraged an unpatched windows vulnerability. NotPetya did the same. So, what are the weaknesses?
A lack of patching – We continue to shoot ourselves in the foot here, because we don’t have solid protection and prevention routines that include the patching of operating systems and applications — especially those leveraged by ransomware authors to gain access.
Not enough (reliable) backups – A lack of validated backups — the primary ransomware recovery tool — can leave us out in the cold and unproductive. It’s a simple equation: if you have backups, you choose recovery over ransom.
User awareness – Users simply don’t understand the threat, the impact, or the cost of a ransomware infection. But, nor should they really — they have a job to do in accounting or sales, not IT security. Even so, putting in solid phishing training and testing can make a material difference.
A lack of least privilege – The more access a user has, the greater scope of infection the ransomware can have. With 71% of end users say they have access to company data they should not be able to see, IT has some serious work to do to ensure privileges are locked down.
No layered defense – A single security solution, such as an antivirus, can only do so much to protect the organization. You need solutions like IPS, an email gateway, endpoint protection, and more all working on concert to give ransomware as little a chance of succeeding as possible.
Doing something about the ransomware problem
What should you do to stop ransomware being so successful? Hide? Run away? Unplug the internet? Probably none of those ideas are likely to solve this problem, although out of sight and all that. I mentioned briefly above, the idea of many thin layers of defense, and while ‘defense in depth’ might seem a little old school and became extinct when we lost control of the network perimeter, there are some ideas we can borrow:
Defense in depth – Make sure you have a solid, proactive security stance in place, including: patching, least privilege, user training, etc.
Protect the endpoint – Desktop and endpoint protection solutions can offer some degree of protection, however, keep in mind that malware can adapt itself to these solutions and circumvent them.
Plan for the worst – Ransomware seems to find a way and you need to make sure you can recover when it does. Backups, off-site backups and backups on different media types are essential. Make sure you test their recovery too, as you don’t want to be finding out how to restore a backup in anger. They say you train hard to fight easy. Never has that been more true for IT contingency planning.
Get these three things right, and you’ll be a lot closer to stopping the rain of ransomware from ruining your day, night or weekend.

It can be daunting to step into the often unfamiliar world of security, where you can at times be inundated with technical jargon (and where you face real consequences for making the wrong decision). Employing a Managed Service Provider or MSSP is often in the best interest of small and medium businesses (SMBs).
In a study performed by Ponemon Institute, 34% of respondents reported using a managed service provider (MSP) or managed security service provider (MSSP) to handle their cybersecurity, citing their lack of personnel, budget, and confidence with security technologies as driving factors. But how do you find a trustworthy partner to manage your IT matters?
Here are the top 3 questions any business should ask a potential security provider before signing a contract:
1 – Are you an established and reputable managed service provider?
Okay, this is one that you’ll probably research before reaching out. Look at how long the company has been in business and who their current clients are. Are you confident that they can anticipate the unique technology needs of your business?
2 – Have you worked with other organizations who have technology needs like mine?
You will want to work with MSPs who understand your business and are able to make technology decisions based on your unique needs. Make sure they have a solid track record with other businesses of your size. If your industry has particular compliance concerns or makes heavy use of specialized programs, make sure they have experience with other customers in your industry.
3 – What does your menu of services offer?
Make sure they round out these services with key security offerings. To make sure they have basic IT security controls in place, ask them about industry buzzwords like asset inventory, patch management, access management, continuous monitoring, vulnerability scanning, antivirus and firewall management. The specifics of their answers aren’t as important as a confident, well considered plan.
Security-minded MSPs’ will make sure your software and you web surfing habits don’t provide cyber-criminals with backdoor access to your systems. They will make sure your network is secure, and they will install antivirus on all your computers. Bonus points if they are forward-thinking enough to include Security Awareness Training. Make sure you understand the services that they offer, and ask if any of these services have extra costs.
While these are not all of the questions you should consider asking a potential service provider, they can help get the conversation started and ensure you only work with service providers who meet your unique needs service providers who meet your unique needs.
