  • Using DNS to weaken Locky ransomware threat

    Ransomware and other cyberthreats often go unseen by traditional detection methods like antivirus, deep packet inspection (DPI) or sandboxing. In fact, a report by Lastline Labs indicates that 51% of zero-day malware—threats that strike before developers have time to release a patch—is undetected by anti-virus solutions. So what can security professionals do to stop attacks? The answer lies, in part, in DNS.

    One of the most powerful ransomware threats currently targeting individuals and organizations is Locky, which infects up to 100,000 devices per day, of which 3% submit payments. Cybersecurity experts estimate that Locky possesses 17% of the entire global market share for all ransomware infections.

    First, let’s look at a few statistics that demonstrate the power and expense of Locky:

    Locky is typically delivered through aggressive spam campaigns, often claiming to be an invoice. Despite the known dangers of clicking on links in unknown emails, Locky is so sly it entices even trained IT staff to click on obscure messages and activate downloads.

    Once a download has completed, Locky connects with its Command & Control (C&C) server to get a cryptographic key to use for encryption. There are three known mechanisms for Locky to reach its C&C hosts:

    1. Direct IP communication
    2. A number of fixed domains
    3. A time-based Domain Generation Algorithm (DGA) that creates a set of random-looking domains that are only valid for a few days

    Here is where DNS can play a role. DNS data can be analyzed to identify C&C connection mechanisms. When these communications are blocked, Locky’s ability to obtain encryption keys is limited, giving infected users a better chance of being protected.

    Unfortunately, the DGA used by Locky to generate domains and get encryption keys is marked with the current time period combined with a secret seed, making it harder to block new domains quickly. Locky changes seeds frequently, and reverse engineering current versions of the malware to discover each new seed takes time. Every new seed indicates another wave in the life of the exploit, so until there is an accurate way to identify traffic associated with Locky, it can’t be permanently blocked.

    But examination of a worldwide feed of anonymized DNS queries, along with anomaly detection and correlation technology, makes it possible to identify suspected domains used by Locky to download encryption keys in real time. ForcePoint is one company that has done some work to reverse engineer the DGA used by Locky. By using the existing DGA and conducting some additional processing of suspect domains, it is possible to determine new seeds used by Locky, thereby enumerating all future new domains Locky will use.

    Below is a sampling of more recent domains created by Locky as detected by our DNS algorithms:

    • mrjuvawlwa[.]xyz
    • uydvrqwgg[.]su
    • uwiyklntlxpxj[.]work
    • owvtbqledaraqq[.]su
    • udfaexci[.]ru
    • eabfhwl[.]ru
    • olyedawaki[.]pl
    • uxwfukfqxhydqawmf[.]su
    • ikdcjjcyjtpsc[.]work
    • wrbwtvcv[.]su
    • osxbymbjwuotd[.]click
    • qtuanjdpx[.]info

    As Locky and other types of ransomware become more adept at avoiding detection and remediation, new strategies need to be used to combat them. Many of the new cyberthreat strategies make traditional malware block lists less effective. Facing DGAs with fast-changing seeds, security researchers must constantly identify the new seeds used by each wave of phishing to pre-generate domains. Once new seeds are released the old ones immediately become obsolete.

    By utilizing a broad set of DNS query data, it is possible to detect and track the evolution of generated domains through a variety of algorithmic methods such as clustering, reputation scoring, reverse engineering and additional methods that continuously evolve. Recent innovations include anomaly detection algorithms, new domain clustering and a Domain Reputation System that resulted in almost 100,000 domains and C&Cs provisioned daily for blocking.

    By employing these advanced methods, suspicious domains can be detected with a high level of accuracy very quickly, and false positives can also be weeded out so good traffic can still reach legitimate sites. Currently, this is the best defense against Locky. Service providers and companies can use this technique to protect their online users from having their files encrypted, and identify machines that have been infected.

    Locky provides ample evidence that attackers are continuously innovating. Staying one step ahead requires cybersecurity expertise and real-time processing of massive, worldwide data sets to uncover malicious activity. Blocking traffic to these domains is a good way to avoid the threat of Locky, and expert security teams that take the right steps to understand its behavior and put appropriate measures in place to protect would-be victims will render cyberthreats much less effective.


  • New Spam Campaign Distributes Locky Ransomware and Kovter Trojan Combined

    Criminals have taken a liking to the idea of combining multiple types of malware into one distribution campaign. Malware Protection Center researchers discovered a string of email messages using malicious attachments to spread both Locky ransomware and the Kovter Trojan. It is not the first time these two types of malware are distributed in the same campaign, as dual-pronged spam campaigns have become more common as of late.

    This morning we noticed the start of a campaign using  New notice to Appear in Court as the email subject. The attachments are identical to the Typical .JS, .WSF, .lnk file inside a double zip. All the sites seen so far today are the same sites used in the USPS, FedEx, UPS current campaigns.  I am sure that both campaigns will continue side by side. It is very likely that different “affiliates” are using the same distribution network, but each one prefers a different email lure to gain victims.

    The attachments all start with a zip named along the lines of Notice_00790613.zip which contain another zip Notice_00790613.doc.zip which in turn contains Notice_00790613.doc.js

    Criminals Step Up Malware Distribution

    It is rather disconcerting to learn opening a malicious email attachment can introduce two different types of malware at the same time. As if the Locky ransomware is not annoying to deal with on its own, computer users will also be affected by the Kovter Trojan. This latter piece of malware specialized in click fraud, generating a lot of illegal advertisement revenue for criminals.

    Through a malicious email attachment, criminals execute a script that contains links to multiple domains where the malware types are downloaded from. By making the attachment a .Ink file, the recipient may click it and have the payload download executed in the background. PowerShell scripts have become a fan favorite among criminals targeting Windows users these days, that much is certain.

    Researchers discovered a total of five hardcoded domains in the script from where the malware can be downloaded. Both the Locky ransomware and Kovter Trojan payloads are hosted on these platforms, and it is expected more of these domains will continue to pop up over time. Although law enforcement agencies can take down these domains rather easily, criminals will not hesitate to create additional hosting solutions over time.

    As one would expect from these spam email campaigns, the message in question is a fake receipt for a spoofed USPS delivery email. In the attached zip file, there is the malicious .Ink file , which initiates the PowerShell script once opened. One interesting aspect about this script is how it checks if the file is downloaded successfully and if is at least 10KB in size. Once that has been verified, it will stop the process automatically.

    Microsoft researchers feel the use of multiple domain names to download the payload from is a powerful obfuscation technique. Blacklisting one specific URL is a lot easier than dealing with a handful of different domains. Moreover, this method seems to hint at how criminals can easily add more servers to download the malicious payloads from if they want to. A very troublesome development, to say the least.

    Perhaps the most worrisome aspect of this new malware distribution campaign is how criminals continue to update the payloads themselves. Both Kovter and Locky receive regular updates, which means the development of ransomware and click-fraud Trojans is still going on behind the scenes. Moreover, it goes to show criminals will continue to rely on multi-pronged distribution campaigns for malware and ransomware moving forward.


  • Proteus botnet Malware with Remote Access

     

    The Proteus botnet emerged toward the end of November 2016.  Only a few samples of it were found in the wild and, at the moment, it doesn’t seem to have a widespread campaign.  So, what does it do? It launches a multi-layered attack on an infected machine where it runs several processes aimed at coin mining, credential theft, and keylogging.  In addition, the bot can perform on its own; it offers the cybercriminal to send commands over HTTP to download malicious executables and execute them.

     

    In some samples, the botnet disguises itself as a Google Chrome executable. The functionality of the botnet is highly reliant on its C&C (command and control) server, hxxp://proteus-network[.]biz or hxxp://proteus-network[.]ml (the latter is inaccessible). The URL is hardcoded in the sample and is contacted multiple times to obtain necessary credentials for the tasks the botnet performs. The host name also appears in Pastebin, under the URL hxxp://pastebin[.]com/raw/LidbEiiR, in its encrypted form, and the botnet can retrieve the domain from there as well.

     

    The botnet starts by identifying the infected machine and obtaining the operating system’s info (whether 64 or 86 bit), the machine’s name, and the Windows version. All of the information is sent to the C&C to “register” the machine.

     

    After the machine is acknowledged by the C&C, the botnet proceeds to perform different tasks. As the botnet contacts the C&C to receive various pieces of information, the web requests are sent along with an encrypted string specifying the purpose of the request. These encrypted strings perform the following functions:

     

    • api/register – Register the infected machine
    • api/ping – Check if the machine is already registered
    • api/module – Check the mining module
    • api/proxy – Use reverse proxy
    • api/command – Receive commands from the C&C
    • api/account – Receive an account from the C&C
    • api/log – Handle the key logging document

     

    The header section of the HTTP requests is similar throughout the different sections of the source code:

    Content-type: application-json

    Authorization: {2D592824-48DE-49F8-8F96-A40B3904C794}

     

    When contacting the C&C, a POST request is sent with one of the above modes appended to the domain’s name, for example, hxxp://proteus-network.biz/api/log. The C&C sends a response to this request, which is then parsed by the botnet in search for the C&C’s reply.

     

    CheckerTask:

     

    The CheckerTask starts by contacting the C&C with the api/account string appended to the domain’s name. After sending a POST request, it receives a four-tuple composed of an account ID, an e-mail, a password, and the account type. The botnet attempts to access and steal the user’s credentials from a number of online websites, including:

     

    • eBay.com
    • otto.de
    • amazon.de
    • breuninger.com
    • dhl.de
    • netflix.com
    • coderbay.net
    • zalando.de

     

    The majority of these websites are German-based and the botnet searches for German words appearing in the responses. This leads us to believe this specific sample of Proteus targets are German victims. For example, if the message received from the website includes the phrase “stimmen nicht mit den bei uns hinterlegten Daten”, which means, “This does not match the data provided by us”. The botnet attempts to change the password’s first character from lower case to upper case or to append the character “1” to the end of the password and tries to log in again after three seconds. The response from the website is then checked to harvest more information about the victim, including name, address, country, bought and sold items, seller type and the last feedback received.

     

    Some of the websites which the CheckerTask tries to steal the credentials from may include a Captcha to prevent such automated logins. The Proteus botnet uses Death by Captcha (DBC), an API which solves any given Captcha and turns it into a text that the botnet can insert into the website, and proceeds with the login. Using DBC requires a username and a password, which are both hardcoded into the sample to enable Captcha analysis. We have managed to access the DBC account used in the sample, and found that it resolved 200 Captchas so far, which could hint to the number of successfully infected machines.

     

    LoggerTask:

     

    This task performs key logging on the infected machine. It starts by initializing a list of all the keyboard keys, and stores the logged keys into a file called tmpV213.txt found under the TEMP directory. When this file includes more than 250 characters, it is cleared and its content is sent to the C&C along with the api/log string.

     

    CommandsTask:

     

    This task receives commands from the C&C. The botnet sends a request to the C&C with the fingerprint and the api/command string. If the C&C sends a command to download a file, a new directory is created in the TEMP folder using a GUID, and a file called temp.exe is created in that directory. Alternatively, if the command is to “kill”, the process is killed. The task checks for new commands every two minutes.

     

    MiningTask, EMiningTask:

     

    The C&C determines the type of mining which the infected machine attempts, as well as the mining pool it will join. The EminingTask downloads an executable to the TEMP directory with the name loader.exe. The types of mining that appear in the sample are CPU, Zcash, Scrypt, and SHA256. During the mining task, and depending on the chosen type, the resources of the infected machine, such as the memory, CPU, and RAM, are used to provide the computing power necessary to produce the hashes accepted as a proof of work by each method. Even using a pool instead of individual mining, CPU usage soared rapidly and reached 100% in our labs when we ran the sample, which shows the processing power needed for the mining tasks.

     

    Conclusion:

     

    To summarize, the botnet conducts a complex attack: it infects a machine, steals credentials, logs keys and mines for currency, causing CPU level to reach 100%. Although the botnet has many of the crucial implementation tools needed for its attack, it heavily depends on communication with its C&C server and the information it transmits for the execution of its most basic functions.


  • Ransomware developers look to educate victims and Help Decrypt files

    Knowledge is good, At least according to the cybercriminals who are developing ransomware that will give a free decryption key if the victim reads two articles about ransomware.

    A new variant of Koolova was discovered by security researcher Michael Gillespie, that demands the victim read two articles: a Google Security Blog, Stay safe while browsing, and a Bleeping Computer article, Jigsaw Ransomware Decrypted: Will delete your files until you pay the Ransom.

    Lawrence Abrams, said the ransomware itself behaves like Jigsaw in that once it encrypts the files it delivers a scrolling note telling the victim to read stories or else risk having their files deleted. In Jigsaw’s case the demand is for a ransom payment.

  • Spoofed FedEx and USPS Kovter and Locky sites Ransomeware Malware Keeps Spreading

    www.ccrepairservices.com
    Locky Ransomeware New CPRS CCRS Computer Repair Miami Fort Lauderdale Website

    Following on from these  [ FEDEX ] [ USPS ]  posts describing the Spoofed FedEx and USPS ( and other delivery services from time to time) I will endeavour to keep up to date with a list of current sites involved in the spreading of this malware. I will also show the command used that day to obtain the malware. I will add each days new sites to the lists, but please remember that old sites are reused daily until taken down by their hosts.  All the sites used in this malware spreading campaign are hacked / compromised sites.

     

    The script tries the first in the list & then moves down until it gets a reply from the server. You never see the first downloaded file ( counter.js by searching on your computer, that is run directly from temp internet files ) Counter.js then downloads  a different variant of counter.js which in turn downloads 01 first, then 02, then 03 until you get to 05. If any site doesn’t have the file, then it moves to the next site in the list for that particular file. Each site on the list has a full set of the files. but it is rare for the site delivering counter.js to actually download from itself, normally that downloads from a different site on the list. All the files ( apart from the original counter.js) pretend to be png ( image files). They are actually all renamed .exe files or a renamed php script listing the files to be encrypted. Counter.js contains the list of sites to download from, which includes many of the sites listed in the original WSF, JS, VBS or other scripting file and normally one or 2 extra ones. to get the second counter.js you need to change the &r=01 at the end of the url to &m=01 ( or 02-05). This second counter.js contains additional sites to download from which frequently includes sites from the previous days lists that are not already included in the WSF or first counter.js.

    I only accidentally  found out about the second /3rd /4th /5th  counter.js when I made a mistake in manually decoding the original wsf file ( and the original counter.js) and mistyped/ miscopied  the &r= and used &m= instead. Obviously it is a belt and braces approach to making sure the actual malware gets downloaded to a victim’s computer when urls or sites are known about and blocked by an antivirus or web filter service.

  • Mobile banking trojan now has encryption and is targeting over 2000 apps

    Security experts at Kaspersky Lab have discovered a modification of the mobile banking Trojan, Faketoken, which can encrypt user data. Kaspersky Lab has detected several thousand Faketoken installation packages capable of encrypting data, the earliest of which dates back to July 2016.

    Disguised as various programs and games, including Adobe Flash Player, the modified Trojan can also steal credentials from more than 2000 Android financial applications.

    To date, the modified Faketoken has claimed over 16,000 victims in 27 countries, with the most located in Russia, Ukraine, Germany and Thailand.

    The newly added data-encryption capability is unusual in that most mobile ransomware focuses on blocking the device rather than the data, which is generally backed-up to the cloud.

    In Faketoken’s case, the data – including documents and media files such as pictures and videos – is encrypted using AES symmetric encryption which can, in some cases, be decrypted by the victim without paying a ransom.

    During the initial infection process, the Trojan demands administrator rights, permission to overlay other apps or to be a default SMS application – often leaving users with little or no choice but to comply. Among other things, these rights enable Faketoken to steal data: both directly, like contacts and files, and indirectly, through phishing pages.

    The Trojan is designed for data theft on an international scale. Once all the necessary rights are in place, it downloads a database from its command and control server containing phrases in 77 languages for different device localisations.

    These are used to create phishing messages to seize passwords from users’ Gmail accounts. The Trojan can also overlay the Google Play Store, presenting a phishing page to steal credit card details.

    In fact, the Trojan can download a long list of applications for attack and even an HTML template page to generate phishing pages for the relevant apps. Kaspersky Lab researchers uncovered a list of 2249 financial applications.

    Intriguingly, the modified Faketoken also tries to replace application shortcuts for social media networks, instant messengers and browsers with its own versions. The reason for this is unclear as the substitute icons lead to the same legitimate applications.

    “The latest modification of the Faketoken mobile banking Trojan is interesting in that some of the new features appear to provide limited additional benefit for the attackers. That doesn’t mean we shouldn’t take them seriously. They may represent the groundwork for future developments, or reveal the ongoing innovation of an ever-evolving and successful malware family. In exposing the threat, we can neutralise it, and help to keep people, their devices and their data safe,” says Roman Unuchek, senior malware analyst at Kaspersky Lab.


  • New KillDisk wiper varient threatens industrial control networks with Ransomware Trojan

    The TeleBots gang, which recently attacked Ukrainian banks with KillDisk malware that used Mr. Robot imagery (pictured), may now be targeting industrial control systems with a ransomware variant.

    The TeleBots gang, which recently attacked Ukrainian banks with KillDisk malware that used Mr. Robot imagery (pictured), may now be targeting industrial control systems with a ransomware variant.

    The KillDisk disk-wiper program that was used in conjunction with BlackEnergy malware to attack Ukrainian energy utilities has evolved into ransomware that may be targeting industrial-control networks.

    According to researchers at CyberX, the new variant was developed by the TeleBots cybergang, which recently emerged from the Sandworm threat group that is believed to have disrupted the Ukrainian power grid offline in December 2015 and January 2016, and allegedly compromised U.S. industrial-control systems and SCADA systems in 2014. Earlier this year, ESET researchers reported that TeleBots was a using different version of KillDisk to conduct cybersabotage attacks against the Ukrainian financial sector.

    In a blog post on Tuesday, CyberX reported that the ransomware variant is distributed via malicious Office attachments and displays a pop-up message demanding 222 Bitcoins, which is currently the equivalent of approximately $206,000. The variant’s exorbitant ransom and its link to Sandworm suggests that the group could be actively launching ransomware attacks against industrial-control networks.

    KillDisk uses a mix of RSA 1028 public key and AES shared key algorithms to encrypt local hard-drives and network-mapped folders that are shared across organizations, CyberX further reported.


  • Android Trojan Switcher Infects Routers via DNS Hijacking – Android Trojan Switcher Infects Routers via DNS Hijacking

    A new Android Trojan uses a victims’ devices to infect WiFi routers and funnel any users of the network to malicious sites. The malware doesn’t target users directly – instead its goal is to facilitate further attacks by turning victims into accomplices.

     

    Researchers at Kaspersky Lab, who discovered the malware and dubbed it Switcher Trojan, claim they’ve seen two versions of the malware. Attackers have used both iterations to commandeer 1,280 wireless networks, most of them in China, according to Nikita Buchka, a mobile security expert with the firm.

    One version of the malware mimics a mobile client for the Chinese search engine Baidu. Another passes itself off as a version of an app used for locating and sharing WiFi login information. Once a victim has downloaded one of the versions, it gets to work attacking the router.

    The malware does so by carrying out a brute-force password guessing attack on the router’s admin web interface. Once in, Switcher swaps out the addresses of the router’s DNS servers for a rogue server controlled by the attackers along with a second DNS, in case the rogue one goes down.

    This makes it so queries from devices on the network are re-routed to the servers of the attacker, something that can open victims to redirection, phishing, malware and adware attacks.

    “The ability of the Switcher Trojan to hijack [DNS] gives the attackers almost complete control over network activity which uses the name-resolving system, such as internet traffic,” Kaspersky Lab said Wednesday, “The approach works because wireless routers generally reconfigure the DNS settings of all devices on the network to their own – thereby forcing everyone to use the same rogue DNS.”

    The creators of the Trojan were a little sloppy when it came to crafting parts of its command and control website however; they left a table complete with internal infection statistics publicly viewable. According to Buchka, who has reviewed the site, the attackers boast to have infiltrated 1,280 WiFi networks over the last several weeks.

    In a Securelist post on the malware posted Wednesday Buchka cautioned users to review their routers’ DNS settings for the following rogue servers: 101.200.147.153, 112.33.13.11, and 120.76.249.59. He also took the opportunity to encourage users – although for many it goes without saying – to verify that they’ve changed their routers’ default login and passwords.

    Several weeks ago a handful of router users in Germany fell victim when a variant of Mirai, the nasty malware that’s become synonymous with internet of things vulnerabilities, took hold of their devices. While those routers didn’t suffer from a hardcoded username/password vulnerability, they did have port 7547, usually used by internet service providers to remotely manage the device, open.

    The behavior of Switcher is somewhat similar to that of DNSChanger, malware that’s been repurposed as an exploit kit as of late. A recent campaign observed by Proofpoint was targeting wireless routers and changing DNS entries in order to steal traffic. In that instance routers made by D-Link, Netgear, Pirelli and Comtrend were vulnerable. According to Buchka, the hardcoded names of input fields and the structures of the HTML documents that the Switcher Trojan tries to access suggests it may work only on web interfaces of TP-LINK Wi-Fi routers.


  • Microsoft continues its legacy of spying on its windows users! Windows 10 Privacy Spy destroyer

    DISTROY WINDOWS 10 SPYING – Privacy Concerns

    Microsoft Windows 10 Software

    As we all know since windows 7 Microsoft has altered its operating system to be more user friendly and at the same time collect more user data on its customers, When windows 8 was launched , there were big changes including location platform and many more but now with the new Windows 10 release there are endless limitations on the collection of data being sent to Microsoft.

    Some group has released a piece of software which eliminates all apps, and blocks the data from being sent to Microsoft. I will not comment much on the software but see below what it does block.

    Also a new app by the name of DoNotSpy10 has been created by a German developer pXc-coding.

    Destroy Windows 10 Spying is an app that can block anonymous data being sent, remove apps that can’t be removed the standard way and more. I liked that it can remove some of the Windows default programs that can’t be removed under Apps & Features, an annoyance I immediately discovered since I prefer to “slim” down windows.

    I should note that there are still a few steps to complete, you’ll still need to go online to Microsoft’s site and opt out of the company’s invasive advertising tracking features when using DoNotSpy10 or other piece of software.

    It’s your own fault if you don’t know that Windows 10 is spying on you. That’s what people always say when users fail to read through a company’s terms of service document, right?

    Well, here is Microsoft’s 12,000-word service agreement. Some of it is probably in English. We’re pretty sure it says you can’t steal Windows or use Windows to send spam, and also that Microsoft retains the right to take possession of your first-born child if it so chooses. And that’s only one of several documents you’ll have to read through.

    Actually, here’s one excerpt from Microsoft’s privacy statement that everyone can understand:

    Finally, we will access, disclose and preserve personal data, including your content (such as the content of your emails, other private communications or files in private folders), when we have a good faith belief that doing so is necessary to: 1.comply with applicable law or respond to valid legal process, including from law enforcement or other government agencies; 2.protect our customers, for example to prevent spam or attempts to defraud users of the services, or to help prevent the loss of life or serious injury of anyone; 3.operate and maintain the security of our services, including to prevent or stop an attack on our computer systems or networks; or 4.protect the rights or property of Microsoft, including enforcing the terms governing the use of the services – however, if we receive information indicating that someone is using our services to traffic in stolen intellectual or physical property of Microsoft, we will not inspect a customer’s private content ourselves, but we may refer the matter to law enforcement.

    If that sentence sent shivers down your spine, don’t worry. As invasive as it is, Microsoft does allow Windows 10 users to opt out of all of the features that might be considered invasions of privacy.
