GhostDNS: 100,00 Infected Routers
Several research labs have been releasing their finding on a new take of DNSChanger. A new router-based exploit known as GhostDNS seems to be made up of three variations of DNSChanger. By using Shell DNSChanger, Js DNSChanger, and PyPhp DNSChanger, GhostDNS can infect over 70 different router models. However, GhostDNS is more than the sum of its DNSChanger components. Analysts have also identified that it also is made up of a web admin module, a RougeDNS module, and a phishing module.
GhostDNS scans the internet looking for routers that it can exploit due to vulnerability or weak security by using its scripts to attack poorly secured Web Administration consoles via Shell, Java, Python, PHP to deploy its payload. The primary purpose is to change the devices’ DNS setting to forward traffic to RougeDNS servers. Once this is done the unsuspecting user is redirected to the phishing landing pages of online services when they attempt to go to various web services. Banking portals, Telecom’s, ISP’s and Netflix seem to be among the most common phishing targets of this malware.
While there has been some disagreement about the time frame this campaign has been running, it is widely agreed the campaign has infected over 100,000 routers with 86% located in Brazil. The other 24% have been reported across other South American countries. The DNS redirection service know as Rouge has been detected on many notable cloud services like Amazon, OVH, Google, Telefonica, and Oracle but researchers have been in contact with larger networks and ISP’s to shut down the network.
The GhostDNS payload can deliver over 100 scripts via remote access or utilizing exploits, and can attack hardware from older HP (3Com), A-Link, Alcatel / Techicolor, Antena, C3-Tech, Cisco, D-Link, Elsys, Fibrehome, Fiberlink, Geneko, Greatek, Huawei, Intelbras, Kaiomy, LinkOne, MikroTik, MPI Networks, Multilaser, OIWTECH, Perfect, Qtech, Ralink, Roteador, Sapido, Secutech, Siemens, Technic, Tenda, Thomson, TP-Link, Ubiquiti, Viking, ZTE, and Zyxel routers.
Analysts have some advice to not become a victim this kind of attack. It is recommended that you update your firmware to the latest version available for your router and use complex and strong passwords. Consider disabling any web administration on your device. Finally, hardcode your DNS setting to use only trusted DNS servers in both your Router and OS.

Security baseline (DRAFT) for Windows 10 v1809 and Windows Server 2019
icrosoft is pleased to announce the draft
release of the security configuration baseline settings for Windows 10 version 1809 (a.k.a., “Redstone 5” or “RS5”), and for Windows Server 2019. Please evaluate these proposed baselines and send us your feedback via blog comments below.
Download the content here: Windows-10-1809-Security-Baseline-DRAFT.zip
The downloadable attachment to this blog post includes importable GPOs, a PowerShell script for applying the GPOs to local policy, custom ADMX files for Group Policy settings, documentation in spreadsheet form and as a Policy Analyzer file (MSFT-Win10-v1809-RS5-WS2019-DRAFT.PolicyRules). In this release, we have changed the documentation layout in a few ways:
- MS Security Baseline Windows 10 v1809 and Server 2019.xlsx – multi-tabbed workbook listing all Group Policy settings that ship in-box with Windows 10 v1809 or Windows Server 2019. Columns for “Windows 10 v1809,” “WS2019 Member Server,” and “WS2019 DC” show the recommended settings for those three scenarios. A small number of cells are color-coded to indicate that the settings should not be applied to systems that are not joined to an Active Directory domain. Cells in the “WS2019 DC” columns are also highlighted when they differ from the corresponding cells in the “WS2019 Member Server” column. Another change from past spreadsheets is that we have combined tabs that used to be separate. Specifically, we are no longer breaking out Internet Explorer and Windows Defender AV settings into separate tabs, nor the settings for LAPS, MS Security Guide, and MSS (Legacy). All these settings are now in the Computer and User tabs.
- BaselineDiffs-to-v1809-RS5-DRAFT.xlsx – This Policy Analyzer-generated workbook lists the differences in Microsoft security configuration baselines between the new baselines and the corresponding previous baselines. The Windows 10 v1809 settings are compared against those for Windows 10 v1803, and the Windows Server 2019 baselines are compared against those for Windows Server 2016.
- Windows 10 1803 to 1809 New Settings.xlsx – Lists all the settings that are available in Windows 10 v1809 that were added since Windows 10 v1803. (We used to highlight these settings in the big all-settings spreadsheets.)
- Server 2016 to 2019 New Settings.xlsx – Lists all the settings that are available in Windows Server 2019 that were added since Windows Server 2016. (We used to highlight these settings in the big all-settings spreadsheets.)
Highlights of the differences from past baselines, which are listed in BaselineDiffs-to-v1809-RS5-DRAFT.xlsx:
- The MS Security Guide custom setting protecting against potentially unwanted applications (PUA) has been deprecated, and is now implemented with a new setting under Computer Configuration\...\Windows Defender Antivirus.
- We have enabled the “Encryption Oracle Remediation” setting we had considered for v1803. At the time we were concerned that enabling the newly-introduced setting would break too many not-yet-patched systems. We assume that systems have since been brought up to date. (You can read information about the setting hereand here.)
- Changes to Virtualization-Based Security settings (used by Credential Guard and Code Integrity):
- “Platform Security Level” changed from “Secure Boot and DMA Protection” to “Secure Boot.” If system hardware doesn’t support DMA protection, selecting “Secure Boot and DMA Protection” prevents Credential Guard from operating. If you can affirm that your systems support the DMA protection feature, choose the stronger option. We have opted for “Secure Boot” (only) in the baseline to reduce the likelihood that Credential Guard fails to run.
- Enabled the new System Guard Secure Launch setting which will enable Secure Launch on new capable hardware. Secure Launch changes the way windows boots to use Intel Trusted Execution Technology (TXT) and Runtime BIOS Resilience features to prevent firmware exploits from being able to impact the security of the Windows Virtualization Based Security environment.
- Enabled the “Require UEFI Memory Attributes Table” option.
- Enabled the new Kernel DMA Protection feature described here. The “External device enumeration” policy controls whether to enumerate external devices that are not compatible with DMA-remapping. Devices that are compatible with DMA-remapping are always enumerated.
- Removed the BitLocker setting, “Allow Secure Boot for integrity validation,” as it merely enforced a default that was unlikely to be modified even by a misguided administrator.
- Removed the BitLocker setting, “Configure minimum PIN length for startup,” as new hardware features reduce the need for a startup PIN, and the setting increased Windows’ minimum by only one character.
- Enabled the new Microsoft Edge setting to prevent users from bypassing certificate error messages, bringing Edge in line with a similar setting for Internet Explorer.
- Removed the block against handling PKU2U authentication requests, as the feature is increasingly necessary.
- Removed the configuration of the “Create symbolic links” user rights assignment, as it merely enforced a default, was unlikely to be modified by a misguided administrator or for malicious purposes, and needs to be changed to a different value when Hyper-V is enabled.
- Removed the deny-logon restrictions against the Guests group as unnecessary: by default, the Guest account is the only member of the Guests group, and the Guest account is disabled. Only an administrator can enable the Guest account or add members to the Guests group.
- Removed the disabling of the xbgm (“Xbox Game Monitoring”) service, as it is not present in Windows 10 v1809. (By the way, consumer services such as the Xbox services have been removed from Windows Server 2019 with Desktop Experience!)
- Removed Credential Guard from the Domain Controller baseline. (Credential Guard is not useful on domain controllers and is not supported there.)
- Created and enabled a new custom MS Security Guide setting for the domain controller baseline, “Extended Protection for LDAP Authentication (Domain Controllers only),” which configures the LdapEnforceChannelBinding registry value described here.
- The Server 2019 baselines pick up all the changes accumulated in the four Windows 10 releases since Windows Server 2016.

NIST final public draft Special Publication 800-37, Revision 2 NIST announces the final public draft Special Publication 800-37, Revision 2, Risk Management Framework for Information Systems and Organizations--A System Life Cycle Approach for Security and Privacy. There are seven major objectives for this update:
The addition of the Prepare step is one of the key changes to the RMF—incorporated to achieve more effective, efficient, and cost-effective security and privacy risk management processes. In addition to seeking your comments on this final public draft, we are specifically seeking feedback on a new RMF Task P-13, Information Life Cycle. The life cycle describes the stages through which information passes, typically characterized as creation or collection, processing, dissemination, use, storage, and disposition, to include destruction and deletion. Identifying and understanding all stages of the information life cycle have significant implications for security and privacy. We are seeking comment on how organizations would executive this task and how we might provide the most helpful discussion to assist organizations in the execution. The public comment periodfor the draft publication is October 2 through October 31. Please submit comments using the comment template to email@example.com.
- To provide closer linkage and communication between the risk management processes and activities at the C-suite or governance level of the organization and the individuals, processes, and activities at the system and operational level of the organization;
- To institutionalize critical risk management preparatory activities at all risk management levels to facilitate a more effective, efficient, and cost-effective execution of the RMF;
- To demonstrate how the NIST Cybersecurity Framework can be aligned with the RMF and implemented using established NIST risk management processes;
- To integrate privacy risk management processes into the RMF to better support the privacy protection needs for which privacy programs are responsible;
- To promote the development of trustworthy secure software and systems by aligning life cycle-based systems engineering processes in NIST Special Publication 800-160, Volume 1, with the relevant tasks in the RMF;
- To integrate security-related, supply chain risk management (SCRM) concepts into the RMF to address untrustworthy suppliers, insertion of counterfeits, tampering, unauthorized production, theft, insertion of malicious code, and poor manufacturing and development practices throughout the SDLC; and
- To allow for an organization-generated control selection approach to complement the traditional baseline control selection approach and support the use of the consolidated control catalog in NIST Special Publication 800-53, Revision 5.

Great articel about Maleware and Small Businesses
Small businesses targeted by highly localized Ursnif campaign
Cyber thieves are continuously looking for new ways to get people to click on a bad link, open a malicious file, or install a poisoned update in order to steal valuable data. In the past, they cast as wide a net as possible to increase the pool of potential victims. But attacks that create a lot of noise are often easier to spot and stop. Cyber thieves are catching on that we are watching them, so they are trying something different. Now we’re seeing a growing trend of small-scale, localized attacks that use specially crafted social engineering to stay under the radar and compromise more victims. In social engineering attacks, is less really more?
A new malware campaign puts that to the test by targeting home users and small businesses in specific US cities. This was a focused, highly localized attack that aimed to steal sensitive info from just under 200 targets. Macro-laced documents masqueraded as statements from legitimate businesses. The documents are then distributed via email to target victims in cities where the businesses are located. With Windows Defender AV’s next gen defense, however, the size of the attack doesn’t really matter.
Several cloud-based machine learning algorithms detected and blocked the malicious documents at the onset, stopping the attack and protecting customers from what would have been the payload, info-stealing malware Ursnif

I don’t like writing breach stories because they occur far too often. On the other hand, when the breach is the fault of the sales merchant, one hopes exposure would cause a renewed interest in other merchants to better secure their retail websites to assure such data loss doesn’t happen to them.
With the numbers of breaches so large, how easily we forget that back in June, Magecart applied a kind of cross-site-scripting (XSS) attack to effectively digitally skim the credit card information from Ticketmaster buyers used for payment. In defense of Ticketmaster, the actual attack appeared to be a code insertion compromise against Inbenta, a thirdparty supplier for their website. Although obfuscated, and having no impact on the site’s functionality, the subtle change captured and diverted the information to Magecartowned servers with legitimate looking names.
This attack was nothing new to Magecart, who’s been behind such malaise since 2015 and focuses on e-commerce. At the time of the Ticketmaster breach, RiskIQ believed that there were over 800 different commerce websites also targeted based on their analysis. Clearly Magecart continued with attacks as evidenced by the large compromise of British Airways (having lost over 380,000 transactions). One might imagine that other smaller sites are also being targeted based on the announcement that just this week ABC-CBN (who’s on-line store was compromised) may have lost information on 213 customers.
You’d think with such publicity, e-commerce sites, especially those with a large customer base would be watching for similar Magecart activity to assure they don’t fall victim. Or not. Per Threatpost yesterday, “Newegg is a top online merchant with tens of millions of registered users in 50 countries, according to its website. It sells a range of consumer electronics, entertainment, smart-home and gaming products, and is the 161st most popular site in the U.S. according to Alexa. In all, it receives more than 50 million site visitors per month. And between Aug. 14 and Sept. 18, a Magecart-linked payment skimmer was active on the Newegg site”. Like the attacks on the other e-commerce sites, with an eloquent injection of only 8 lines of code (similar to the code used in the British Airways incident but improved), Magecart diverted information to a domain with a legitimate Comodo-issued certificate called neweggstats[.]com. In the analysis of these attacks, RiskIQ further states: “Magecart attacks are surging—RiskIQ’s automatic detections of instances of Magecart breaches pings us almost hourly.”
Who’s to blame for these breaches? Clearly web service providers in the e-commerce arena need to improve their approaches to security. How many sites have been compromised? Perhaps there are some we may never know about, but for many more, my guess is we will learn about them in the near future as e-commerce providers take a closer look at their websites for some unauthorized Magecart additions.

Draft Cybersecurity Practice Guide SP 1800-14, Protecting the Integrity of Internet Routing: Border Gateway Protocol (BGP) Route Origin Validation, is Available for Comment Draft Cybersecurity Practice Guide SP 1800-14, Protecting the Integrity of Internet Routing: Border Gateway Protocol (BGP) Route Origin Validation, is Available for Comment It is difficult to overstate the importance of the internet to modern business and society in general. The internet is not a single network, but rather a complex grid of independent interconnected networks that relies on a protocol known as Border Gateway Protocol (BGP) to route traffic to its intended destination.
Unfortunately, BGP was not designed with security in mind and a route hijack attack can deny access to internet services, misdeliver traffic to malicious endpoints, and cause routing instability. A technique known as BPG route origin validation (ROV) is designed to protect against route hijacking. NIST’s National Cybersecurity Center of Excellence (NCCoE), together with several technology vendors, has developed proof-of-concept demonstrations of BGP ROV implementation designed to improve the security of the internet's routing infrastructure. Comments for this draft are due by October 15, 2018. To review Draft Special Publication (SP) 1800-14, and for information on submitting comments, please visit the links below.
