Research

After many years in the wilderness of non-innovation, there has been a lot of activity in the network security space over the past few years. Your grand-pappy’s firewall is dead and a lot of organizations are in the process of totally rebuilding their perimeter defenses. At the same time, the perimeter gradually becomes even more a mythical beast of yesteryear, forcing folks to ponder how to enforce network isolation and segmentation while the underlying cloud and virtualized technology architectures are built specifically to break isolation and segmentation. The good news is that there will be lots of good stuff to see and talk about at the RSA Conference. But, as always, it’s necessary to keep everything in context to balance hype against requirements, with a little reality sprinkled on top. Whatever the question, the answer is NGFW… For the 4th consecutive year we will hear all about how NGFW solves the problem. Whatever the problem may be. Of course that’s a joke, but not really. All the vendors will talk about visibility and control. They will talk about how many applications they can decode, and how easy it is to migrate from your existing firewall vendor and instantaneously control the scourge that is Facebook chat. As usual they will be stretching the truth a bit. Yes, NGXX network security technology is maturing rapidly. But unfortunately it’s maturing much faster than most organizations’ ability to migrate their rules to the new application-aware reality. So the catchword this year should be operationalization. Once you have the technology, how can you make best use of it? That means talking about scaling architectures, policy migration, and ultimately consolidation of a lot of separate gear you already have installed in your network. The other thing to look out for this year is firewall management. This niche market is starting to show rapid growth, driven by the continued failure of the network security vendors to manage their boxes, and accelerated by the movement towards NGFW – which is triggering migrations between vendors, and driving a need to support heterogenous network security devices, at least for a little while. If you have more than handful of devices you should probably look at this technology to improve operational efficiency. Malware, malware, everywhere. The only thing hotter than NGFW in the network security space are network-based malware detection devices. You know, the boxes that sit out on the edge of your network and explode malware to determine whether each file is bad or not. Some alternative approaches have emerged that don’t actually execute the malware on the device – instead sending files to a cloud-based sandbox, which we think is a better approach for the long haul, because exploding malware takes a bunch of computational resources that would better be utilized to enforce security policy. Unless you have infinite rack space – then by all means continue to buy additional boxes for every niche security problem you have. Reasonable expectations about how much malware these network-resident boxes can actually catch are critical, but there is no question that network-based malware detection provides another layer of defense against advanced malware. At this year’s show we will see the first indication of a rapidly maturing market: the debate between best of breed and integrated solution. That’s right, the folks with standalone gateways will espouse the need for a focused, dedicated solution to deal with advanced malware. And Big Network Security will argue that malware detection is just a feature of the perimeter security gateway, even though it may run on a separate box. Details, details. But don’t fall hook, line, and sinker for this technology to the exclusion of other advanced malware defenses. You may go from catching 15% of the bad stuff to more than 15%. But you aren’t going to get near 90% anytime soon. So layered security is still important regardless of what you hear. RIP, Web Filtering For those network security historians this may be the last year we will be able to see a real live web filter. The NGFW meteor hit a few years ago, and it’s causing a proverbial ice age for niche products including web filters and on-premise email security/anti-spam devices. The folks who built their businesses on web filtering haven’t been standing still, of course. Some moved up the stack to focus more on DLP and other content security functions. Others have moved whole hog to the cloud, realizing that yet another box in the perimeter isn’t going to make sense for anyone much longer. So consolidation is in, and over the next few years we will see a lot of functions subsumed by the NGFW. But in that case it’s not really a NGFW, is it? Hopefully someone will emerge from Stamford, CT with a new set of stone tablets calling the integrated perimeter security device something more relevant, like the Perimeter Security Gateway. That one gets my vote, anyway, which means it will never happen. Of course the egress filtering function for web traffic, and enforcement of policies to protect users from themselves, are more important than ever. They just won’t be deployed as a separate perimeter box much longer. Protecting the Virtually Cloudy Network We will all hear a lot about ‘virtual’ firewalls at this year’s show. For obvious reasons – the private cloud is everywhere, and cloud computing inherently impacts visibility at the network layer. Most of the network security vendors will be talking about running their gear in virtual appliances, so you can monitor and enforce policies on intra-datacenter traffic, and even traffic within a single physical chassis. Given the need to segment protected data sets and how things like vMotion screw with our ability to know where anything really is, the ability to insert yourself into the virtual network layer to enforce security policy is a good thing. At some point, that is. But that’s the counterbalance you need to apply at the conference. A lot of this technology is still glorified science experiments, with much

Gunter Ollmann (now of IOActive) offers a very interesting analysis of why vulnerability disclosures don’t really matter any more. But I digress. The crux of the matter as to why annual vulnerability statistics don’t matter and will continue to matter less in a practical sense as times goes by is because they only reflect ‘Disclosures’. In essence, for a vulnerability to be counted (and attribution applied) it must be publicly disclosed, and more people are finding it advantageous to not do that. This is a good point. With an increasingly robust market for weaponized exploits, it’s very unwise to assume that the number of discovered software vulnerabilities bears any resemblance to the number of reported vulnerabilities. Especially given how much more attack surface we expose than the traditional operating system. But Gunter isn’t done yet. With today’s ubiquitous cloud-based services – you don’t own the software and you don’t have any capability (or right) to patch the software. Whether it’s Twitter, Salesforce.com, Dropbox, Google Docs, or LinkedIn, etc. your data and intellectual property is in the custodial care of a third-party who doesn’t need to publicly disclose the nature (full or otherwise) of vulnerabilities lying within their backend systems – in fact most would argue that it’s in their best interest to not make any kind of disclosure (ever!). Oh man, Gunter is opening up the cloudy Pandora’s Box. With the advent of SaaS, these vulnerabilities won’t be disclosed. Unless it’s a hacktivist exploiting the vulnerability, you won’t hear about the exploit either. The data will be lost and the breach will happen. There is nothing for you to patch, nothing for enterprises to control, nothing but cleaning up the mess when these SaaS providers inevitably suffer data losses. We haven’t seen a major SaaS breach yet. But we have all been around way too long to believe that can last. A lot of food for thought here.

Every now and again I can’t decide what to discuss on the Friday summary, so this week I will mention all items on my mind. First, I live near a lot of small airports. There are helicopters training in my area every day, and hardly a week goes by when a collection of WWII planes doesn’t rumble by – very cool! And 20 or so hot-air balloons launch down the street from me every day. So I am always looking up to see what’s flying overhead. This week it was a military drone. I have never given much thought to drones. We obviously have been hearing about them in Afghanistan for years, but it certainly jerks you awake to see one for the first time – overhead in your own backyard. Not sure what I think about this yet, but seeing one in person does have me thinking! … I watched the Super Bowl on my Apple TV this year. I streamed the game from the CBS Sports site to the iMac, and used AirPlay to stream to the Apple TV. That means I got to watch on the big plasma, and the picture quality was nearly as good as DirecTV. Not to give a back-handed compliment, but CBS Sports got a clue that people are actually using this thing they call “The Internet” for content delivery. The only downside was that I had to watch the same three bad commercials every 2 minutes for the entire freakin’ game. But hey, it was free and it was decent quality. Too bad the game sucked. Ahem. Anyway, happy the big networks are less afraid of the Internet and realize they can reach a wider audience by allowing access to content instead of hoarding it. All I need now is an NFL package on the Apple TV and I am set! … If I was going to write code to exfiltrate data from a machine, I think I’d try to leverage Skype. Have you ever watched the outbound traffic it generates? A single IM generated 119 UDP packets to 119 different IP addresses over some 40 ports. It’s using UDP and TCP, has access to multiple items in the keychain, maintains inbound and outbound connections to thousands of IPs outside the Skype domains, occasionally leverages encrypted channels, and dynamically alters where data is sent. I used a network monitor and can’t make heads or tails of the traffic or why it needs to spray data everywhere. That degree of complexity makes hiding outbound content easy, it has a straightforward API, and its capabilities allow very interesting possibilities. Call me paranoid, but I’m thinking of removing Skype because I don’t feel I can adequately monitor it or sufficiently control its behavior. … I’m really starting to look forward to the RSA Conference – despite being over-booked!

Game on! It’s hard to imagine, but this year we are hosting the Fifth Annual RSA Conference Disaster Recovery Breakfast, in partnership with SchwartzMSL and Kulesa Faul (and possibly one more surprise guest). When we started this we had no idea how popular it would be. Much to our surprise it seems that not everyone wants to spend all their time roaming a glitzy show floor or bopping their heads to 110 decibels in some swanky club with a bunch of coworkers wearing logo shirts and dragging around conference bags. (Seriously, what is up with that?!?) As always, the breakfast will be Thursday morning from 8-11 at Jillian’s in the Metreon. It’s an open door – come and leave as you want. We’ll have food, beverages, and assorted recovery items to ease your day (non-prescription only). Remember what the DR Breakfast is all about. No marketing, no spin, just a quiet place to relax and have muddled conversations with folks you know, or maybe even go out on a limb and meet someone new. After three nights of RSA Conference shenanigans, it’s an oasis in a morass of hyperbole, booth babes, and tchotchke hunters. Invite below. See you there. To help us estimate numbers please RSVP to rsvp (at) securosis (dot) com. I (Rich) won’t actually be there this year (probably) or at RSA at all. It seems my wife decided to have a baby that week, so unless the little bugger comes pretty early I’ll be at home for my first RSA in many years. So have one or two for me on Wednesday night, then a few aspirin and Tums for me on Thursday morning at the breakfast. Share:

At the Kaspersky summit in San Juan, Puerto Rico, Chris Soghoian discussed the problem of Android user’s not updating their mobile devices to current software revisions. From Threatpost: “With Android, the situation is worse than a joke, it’s a crisis,” … “With Android, you get updates when the carrier and hardware manufacturers want them to go out. Usually, that’s not often because the hardware vendor has thin [profit] margins. Whenever Google updates Android, engineers have to modify it for each phone, chip, radio card that relies on the OS. Hardware vendors must make a unique version for each device and they have scarce resources. Engineers are usually focused on the current version, and devices that are coming out in the next year.” The core of the issue is that the mobile carriers are not eager to have every one of their mobile users downloading hundreds of megabytes across their networks for patches and OS updates to extend the value of their old phones. For them it’s pure overhead, so they don’t prioritize updates. And the results are pretty staggering, with adoption rates of new iOS software approaching 50% in a week, whereas Android … well, see for yourself. Every mobile security presentation I have been to over the last 18 months devolves into a debate between “Android Security is Better” vs. “iOS security is superior”. But the debate is somewhat meaningless to most consumers, who only carry one or the other, and rarely choose phones based on security. General users don’t go out of their way to patch, and most users (who say they care about security when asked) don’t put much effort into security – including patching. So platform patches are mostly interesting to IT Operations at large enterprises dealing with BYOD, who are trying to keep their employees from becoming infected with mobile malware. Our research shows this has been a primary reason some of the Fortune 1000 don’t allow Android in the enterprise. Just as bad, as Mr. Soghoian points out, carriers also arbitrarily restrict – or ‘cripple’ – device features. There is no clear solution to these problems yet, so good for Chris for drawing attention to the issue – hopefully it will resonate beyond the security community. Share:

Our recently published Early Warning paper put forth the idea of leveraging external threat intelligence to better utilize internal data collection, further shortening the window between weaponized attack and ability to detect said attack. But of course, the Devil is in the details and taking this concept to reality means delving into actually putting these ideas into practice. There are number of different types of “threat intelligence” that can (and should) be utilized in an Early Warning context. We’ve already documented a detailed process map and metric model to undertaking malware analysis (check out our Malware Analysis Quant research). Being able to identify and search for those specific indicators of compromise on your devices can be invaluable to determine the extent of an outbreak. But what can be done to identify malicious activity, if you don’t have the specific IoCs for the malware in question? That’s when we can look at the network to yield information about what may be a problem, even if the controls on the specific device fail. Why look at the network? Obviously it’s very hard to stage attacks, move laterally within an organization, and achieve the objective of data exfiltration without relying on the network. This means the attackers will necessarily leave a trail of bits on the network, which can provide a powerful indication of the kinds of attacks you’re seeing and which devices on your network are already compromised. In Network-based Threat Intelligence: Searching for the Smoking Gun, we’ll going to dig into these network-based indicators and share tactics to leverage these indicators quickly to identify compromised devices. Hopefully shortening this detection window helps to contain imminent damage and prevent data loss. Finally we’ll discuss how this approach allows you to iterate towards a true Early Warning System. We’d like to thank our friends at Damballa for licensing the content at the end of the project, but as always we’ll be developing the research independently in accordance with our Totally Transparent Research methodology. With that pre-amble done, in order to understand how to detect signs of malware on your network, you need to understand how malware gains a presence in a network, spreads within that network, and finally moves the data outside of the network. That’s become known in industry parlance as The Kill Chain. Describing the Attack There has been plenty of research done through the years about how malware does it’s nefarious dealings. The best description of the Kill Chain we’ve seen was done back in 2009 by Mike Cloppert, which we recommend you check out for yourself. To highlight Mike’s terminology, let’s describe (at a high level) how malware works. Source: Security Intelligence: Attacking the Kill Chain Reconnaissance: The attackers first profile their targets. Understanding how the target organization is structured, gleaning information about the control set, and assembling information that can be used in social engineering attacks. Weaponization: Next comes preparing malware to exploit a vulnerability on the device. This involves the R&D efforts to find these exploits, which allow the attacker to gain control of the victim’s device, and the development of a delivery system to get the exploit onto the target device. Delivery: Once the exploit is weaponized, it needs to be delivered to the target. This usually means some kind of effort to get the target to take an action (usually clicking on a link or using an application attack) that would render a web page to deliver the malware. Exploitation: This is the actual running of the exploit code on the target device to provide the attacker with control of the device. This can be a pretty complicated process and take advantage of known or unknown vulnerabilities in either the operating system or application code. Nowadays this tends to be a multi-stage process where a downloader gains control of the machine and then downloads additional exploit code. Another focus of this step is obfuscation of the attack to hide the trail of the attackers and stay below the radar. C2: Known nowadays as Command and Control, this is the process of the newly compromised device establishing contact with the network to receive further instructions. Exfiltration: Once the attackers achieve their goals of their mission, they must package up the spoils and move it to a place where they can pick it up. Again, this can be a rather sophisticated endeavor to evade detection of the stolen data leaving the organization. There has been significant innovation in a number of the aspects of the kill chain, but overall the process remains largely the same. Let’s talk a bit about how each step in the process has evolved over the past 3 years. Let’s start with reconnaissance, since that’s become far easier now that lots of targets seem to publish their life story and sordid details on public social networks. There are tools today (like Maltego) that can automatically assemble a fairly detailed profile of a person by mining social networks. Despite the protestations of many security professionals, folks aren’t going to stop sharing their information on social networks, and that is going to make the attackers recon efforts that much easier. In terms of weaponization, we’ve seen increasing sophistication and maturity in terms of how the exploits are developed and updated. Besides a third party market for good exploits creating a significant economic opportunity for those willing to sell their exploits, you see attackers using modern software development techniques like Agile programming, as well as undertaking sophisticated testing of the attack against not only the targets, but the majority of security software products designed to stop the attack. Finally, attackers now package up their code into “kits” foruse by anyone with a checkbook (or BitCoin account). So sophisticated malware is now within reach of unsophisticated attackers. Awesome. In terms of the delivery step, as mentioned above, given the rapid change inherent to malware many attackers opt to deliver a very small downloader onto the compromised device. Once C&C contact is established, the downloader will receive a

It’s over. Sunday night, when the confetti fell on the Ravens and we finished cleaning up the residual mess from the Super Bowl party, the reality set in. No NFL for months. Yeah, people will start getting fired up about spring training, but baseball just isn’t my thing. Not as a spectator sport. I can take some comfort that in the NFL being a 12-month enterprise now. In a few weeks the combine will give us a look at the next generation of football stars. Then we’ll start following free agency in early March to see who is going to be in and who is out. It’s like Project Runway, but with much higher stakes (and no Tim Gunn). I guess there are other sports to follow, like NCAA Basketball. The March Madness tournament is always fun. Until I’m blown out of all my brackets – then it’s not so fun anymore. But it’s not football. There will be flurries of activity throughout the year. Like when the schedule makers publish the 2013 NFL matchups in mid-April. I dutifully spend a morning putting all the games in my calendar. If only to make sure I don’t schedule business travel around those times. Lord knows, I only get 10-12 opportunities a year to see NFL football live, and no business trip is going to impact that. A man must have his priorities. Then the draft happens at the end of April. Between free agency and the draft you can start to envision what your favorite team will look like next season. Even through the void of no games, there are always shiny football objects to obsess about. If you are a Patriots fan, you can live vicariously through the Gronk throughout the offseason. First he’s making out with some girl, then he’s doing some wacky dance and falling on his $54 million forearm. It’s good to be the Gronk, evidently. Though you figure if he’s making $9MM a year, he could afford a T-shirt, right? There is also an NFL punditry machine that never sleeps. It’s like the security echo chamber times eleventy billion. Hundreds of bloggers, writers, and ponitificators stirring the pot every day. They tweet incessantly and keep our attention focused on even the most minute details. If they aren’t covering the exploits of the Gronk, they are worrying about this guy’s contract negotiations, that guy’s salary cap number, which sap ended up on the waiver wire, some new dude’s endorsement deal, or that other guy’s rehab. No detail is too small to be tweeted and retweeted 20 times in the offseason. Then the real void sets in. After the draft analysis and re-analysis finishes up sometime in May, and they do the OTAs and other activities, things go dead until August. But by that point summer has begun, the kids are off at camp, and life is good. I’m trying to live more in the present, so taking a respite and maybe getting some work done won’t be a bad thing. Before we blink it will be time for training camp in August. At least it’s not hot in Atlanta that time of year. But we persevere anyway and pack up the car, lather on the sunscreen, and watch our modern-day gladiators installing new plays and scheming up ways to keep us on the edge of our seats for another season. We’ll wait in line to get the signature of some 3rd-string linebacker and be ecstatic. Why? Because it means the void will be ending soon. And soon enough Labor Day will usher in another season. –Mike Photo credits: Void originally uploaded by Jyotsna Sonawane Heavy Research We are back at work on a variety of blog series, so here is a list of the research currently underway.

Understanding Identity Management for Cloud Services Architecture and Design Integration Newly Published Papers Building an Early Warning System Implementing and Managing Patch and Configuration Management Defending Against Denial of Service Attacks Securing Big Data: Security Recommendations for Hadoop and NoSQL Environments Pragmatic WAF Management: Giving Web Apps a Fighting Chance Incite 4 U Remembering the basics: Peter Wayner offers a great set of code development security tips. The cynic in me immediately asked, “Where do you get the time to implement these tips?” and “When does the time come to build tools, or when is it time to spend money on security testing products?” But when you look closer, he has chosen tips which are simply good development practices that make code most robust and more stable … they lead to higher-quality code. Rigorous input testing, modular (read: insulated) design, avoiding too many trust assumptions, building on certified code libraries, and so on, are all simply good programming methods. This advice is not “bolt security on”, but instead to embrace good design and implementation techniques to improve security. Good stuff! – AL A new disclosure FAIL: Imagine you are a product vendor who actually cares about security. Someone reports a very serious exploit, says it’s being used in common exploit kits, and it could allow attackers to bypass all your security controls and pwn whoever they want. Not a good day. But you are a proactive type, so you engage your product security incident team and get cracking. Except, as recently discussed by Adobe, all you have is a video of the exploit, no vulnerability details, and eventually the researchers cut off contact. Alrighty then, what next? Rather than forgetting about it, Adobe tried their best to run down potential exploit options and bump up some security fixes that may or may not fix the potential problem, which may or may not be real. I give Adobe a ton of crap for all the security problems in their products, but the security folks definitely deserve some credit for trying their best

Between WikiLeaks imploding, the LulzSec crew going to jail, and APT becoming business as usual, you might think data security was just so 2011, but the war isn’t over yet. Throughout 2012 we saw data security slowly moving deeper into the market, driven largely by mobile and cloud adoption. And slow is the name of the game – with two of our trends continuing from last year, and fewer major shifts than we have seen in some other years. You might mistake this for maturity, but it is more a factor of the longer buying cycles (9 to 18 months on average) we see for data security tools. Not counting the post-breach panic buys, of course. Cloud. Again. ‘Nuff Said? Yes, rumor is strong that enterprises are only using private cloud – but it’s wrong. And yes, cloud will be splattered on every booth like a henchman in the new Aaarnoold movies (he’s back). And yes, we wrote about this in last year’s guide. But some trends are here to stay, and we suspect securing cloud data will appear in this guide for at least another couple years. The big push this year will be in three main areas – encrypting storage volumes for Infrastructure as a Service; a bit of encryption for Dropbox, Box.net, and similar cloud storage; and proxy encryption for Software as a Service. You will also see a few security vendors pop off their own versions of Dropbox/Box.net, touting their encryption features. The products for IaaS (public and private) data protection are somewhat mature – many are extensions of existing encryption tools. The main thing to keep in mind is that, in a public cloud, you can’t really encrypt boot volumes yet so you need to dig in and understand your application architecture and where data is exposed before you can decide between options. And don’t get hung up on FIPS certification if you don’t need FIPS, or will you limit your options excessively. As for file sharing, mobile is the name of the game. If you don’t have an iOS app, your Dropbox/Box/whatever solution/replacement is deader than Ishtar II: The Musical. We will get back to this one in a moment. There are three key things to look for when evaluating cloud encryption. First, is it manageable? The cloud is a much more dynamic environment than old-school infrastructure, and even if you aren’t exercising these elastic on-demand capabilities today, your developers will tomorrow. Can it enable you keep track of thousands of keys (or more), changing constantly? Is everything logged for those pesky auditors? Second, will it keep up as you change? If you adopt a SaaS encryption proxy, will your encryption hamper upgrades from your SaaS provider? Will your Dropbox encryption enable or hamper employee workflows? Finally, can it keep up with the elasticity of the cloud? If, for example, you have hundreds of instances connecting to a key manager, does it support enough network sockets to handle a distributed deployment? If encryption gets in the way, you know what will happen. Is that my data in your pocket? BYOD is here to stay, as we discussed in the Key Themes post, which means all those mobile devices you hate to admit are totally awesome will be around for a while. The vendors are actually lagging a bit here – our research shows that no-one has really nailed what customers want from mobile data protection. This has never stopped a marketing team in the history of the Universe. And we don’t expect it to start now. Data security for BYOD will be all over the show floor. From network filters, to Enterprise DRM, with everything in between. Heck, we see some MDM tools marketed under the banner of data security. Since most organizations we talk to have some sort of mobile/BYOD/consumerization support project in play, this won’t all be hype. Just mostly. There are two things to look for. First, as we mentioned in Key Themes, it helps to know how people plan to use mobile and personal devices in your workplace. Ideally you can offer them a secure path to do what they need to solve their business problems, because if you merely block they they will find ways around you. Second, pay close attention to how the technology works. Do you need a captive network? What platforms does it support? How does it hook into the mobile OS? For example, we very often see features that work differently on different platforms, which has a major impact on enterprise effectiveness. When it comes to data security, the main components that seem to be working well are container/sandboxed apps using corporate data, cloud-enhanced DRM for inter-enterprise document sharing, and containerized messaging (email/calendar) apps. Encryption for Dropbox/Box.net/whatever is getting better, but you really need to understand whether and how it will fit your workflows (e.g., does it allow personal and corporate use of Dropbox?). And vendors? Enough of supporting iOS and Windows only. You do realize that if someone is supporting iOS, odds are they have to deal with Macs, don’t you? Shhh. Size does matter Last year we warned you not to get Ha-duped, and good advice never dies. There will be no shortage of Big Data hype this year, and we will warn you about it continually throughout the guide. Some of it will be powering security with Big Data (which is actually pretty nifty), some of it will be about securing Big Data itself, and the rest will confuse Big Data with a good deal on 4tb hard drives. Powering security with Big Data falls into other sections of this Guide, and isn’t necessarily about data security, so we’ll skip it for now. But securing Big Data itself is a tougher problem. Big Data platforms aren’t architected for security, and some even lacking effective access controls. Additionally, Big Data is inherently about collecting massive sets of heterogenous data for advanced analytics – it’s not like you could just encrypt a single column.

Microsoft and Symantec today announced they have jointly taken down the command and control infrastructure of the Bamital botnet, which managed a massive click-fraud scheme. From Yahoo news: The companies said that the Bamital operation hijacked search results and engaged in other schemes that the companies said fraudulently charge businesses for online advertisement clicks. Bamital’s organizers also had the ability to take control of infected PCs, installing other types of computer viruses that could engage in identity theft, recruit PCs into networks that attack websites and conduct other types of computer crimes. Now that the servers have been shut down, users of infected PCs will be directed to a site informing them that their machines are infected with malicious software when they attempt to search the web. While they had judicial approval to perform the takedown, it’s interesting that they have rendered upwards of a million PCs unable to use the Internet. Click-fraud is technically easy and amazingly profitable, but it’s not something I have often seen law enforcement go after. Some additional details are on the Microsoft blog, and malware cleanup tools are available on the Microsoft Support Site in case your machine was infected. Share:
