On Friday, March 13, the President of the United States (POTUS) held a news conference regarding the global pandemic COVID-19 and declared a national emergency. This declaration will open up $60 billion to help the fight against the virus. Every state has been requested to set up Emergency Operations Centers and every hospital in the United States is activating emergency preparedness plans to meet the needs of Americans everywhere. The declaration also allows officials at the Department of Health and Human Services the ability to waive laws to enable telehealth so that remote doctor visits are feasible. The National Guard has said that it will deploy a maximum of 1,000 troops in six states by the end of the day (Friday). The Guard is also evaluating military bases across the country to use for “isolation housing” to stock medical supplies.

An announcement was made regarding a new partnership with the private sector to increase the capacity to test for COVID-19. 1.4 million tests are to be available next week and 5 million within a month. Pharmacies and retailers are planning to make drive thru tests available in critical locations so that individuals are able to get tested for the virus while remaining in their vehicles. Google is in the process of developing a website to determine whether or not a test is warranted and if so, to facilitate testing at a convenient location. Labs are to provide results within 24-36 hours after testing. On Sunday evening, the public will receive specific guidance on when the website will be operational.

The President also announced a few emergency Executive actions that have been implemented such as waiving interest in all student loans via helped from federal government agencies. Based on the price of oil, the Secretary of Energy has also purchased large quantities of crude oil for storage in the U.S. strategic reserve. Ultimately, these measures are aiming to save the American taxpayer billions of dollars, improve the oil industry, and help establish energy independence. When questioned about other specific targeted measures that the Administration is taking, the President stated that a report will be released in two hours regarding additional steps.

When questioned on the President’s photograph with an individual that was tested positive for COVID-19, he stated that he has no symptoms. When asked about how long the American people will have to remain in an emergency state, the President stated that it is impossible to predict the time element.

Microsoft issued a public advisory yesterday in light of the need for many companies to suddenly shift to an increase in employees working from home in response to the global pandemic COVID-19. The article highlighted the importance of remaining productive without increasing cyber security risk. Some considerations highlighted include implementing official chat tools to allow for a proper communication channel for the workforce, utilization of Azure AD Conditional Access [hXXps://docs.microsoft.com/en-us/azure/active-directory/conditional-access/overview] to secure access to cloud applications, and the Azure AD Application Proxy [hXXps://docs.microsoft.com/en-us/azure/active-directory/manage-apps/what-is-application-proxy] for publishing on-premises applications for remote availability.

Due to the increase in remote work, it is highly likely that organizations will also see an increase in the use of personal devices accessing company data. Therefore, using Azure AD Conditional Access and Microsoft Intune app protection policies [hXXps://docs.microsoft.com/en-us/azure/active-directory/conditional-access/app-protection-based-conditional-access] together can help manage and protect corporate data in approved applications on these personal devices. One of the best ways to improve security for employees working from home is to utilize multi-factor authentication by utilizing Windows Hello biometrics as well as smartphone authentication apps like Microsoft Authenticator.

On August 29th, 2019, a cybersecurity firm, Armis Security, discovered five zero-day vulnerabilities in Cisco Devices collectively referred to as “CDPwn”, which could potentially impact tens of millions of devices. CDPwn consists of five Remote Code Execution vulnerabilities, as well as one Denial of Service vulnerability. CDPwn utilizes the Cisco Discovery Protocol (CDP), which is a layer-2 networking protocol that Cisco devices use to gather information about devices connected to the same network. The CDPwn vulnerabilities could potentially be utilized for the purposes of breaking network segmentation, data exfiltration of corporate network traffic traversing through an organization’s switches and routers, gaining access to additional devices by leveraging man-in-the-middle attacks by intercepting and altering traffic on the corporate switch, and data exfiltration of sensitive information such as phone calls from devices like IP phones and video feeds from IP cameras. Armis Security relayed information about CDPwn to Cisco soon after discovery.

On February, 5th, 2020, Cisco released patches for devices vulnerable to CDPwn exploitation. Cisco said that they are not aware of any malicious use of the CDPwn as of yet. In order to exploit the vulnerabilities, attackers would first need to establish a foothold inside a target’s network, and then hop from device to device (via CDPwn exploitation) to gain significant access and/or control over a network and potentially execute code or cause denial of service.

Many of the vulnerable Cisco products—such as desk phones, web cameras, and network switches—do not auto-update, and need manual patching to receive protection. Enterprise switches and routers are often behind on patches and updates due to avoidance of network downtime. CDP is implemented in virtually all Cisco products, including switches, routers, IP phones and cameras. All those devices ship from the factory with CDP enabled by default. According to Cisco, over 95 percent of Fortune 500 companies use Cisco Collaboration solutions.

Cisco device owners should look up whether or not their devices are listed by Cisco as being susceptible to CDPwn exploitation by going to Cisco’s website. If they are listed as containing CDPwn vulnerabilities, device owners should immediately download and manually install patches from Cisco’s website. Routine updates are recommended for all Cisco devices in order to avoid possible exploitation by malicious actors relying on utilizing unpatched devices as attack vectors for infiltrating enterprise systems.

The following fix action is recommended for Cisco device owners: please refer to the “Affected Products” section of the attached “CISCO CDP vulnerability for DoS.pdf” to determine whether or not your device(s) are listed as having CDPwn vulnerabilities and, if so, refer to the “Fixed Releases” section, and download and install the patch for the device.  A table containing both the affected devices series and links to their respective vulnerability patch instructions has been included below.

Recommendation: Partners and Client organizations should have cyber security teams determine which affected devices they have and patch accordingly.

Recommendation: More frequent updating of Cisco devices.

Details: The National Council of ISACs shared information regarding the Department of Justice’s updated policy for using Unmanned Aircraft Systems (UAS), which was released in November of 2019. 

On November 27, 2019, DOJ published an updated copy of its Policy on the Use of UAS [hXXps://www.justice.gov/jm/9-95000-unmanned-aircraft-systems-uas]. They noted that: 

“In light of advancements in unmanned aircraft system (UAS) technology, and lessons learned from the Federal Bureau of Investigation’s limited use of UAS, the Policy enables the Department of Justice’s law enforcement components to safely and responsibly employ UAS technology within a framework designed to provide accountability and protect privacy and civil liberties. . . The Policy permits the use of UAS only in connection with properly authorized investigations and activities.  It also requires compliance with the Constitution and all applicable laws and regulations, including regulations issued by the Federal Aviation Administration.” 

E-ISAC Analyst Comment: It is useful to maintain awareness of government policy on the use of UAS both to inform knowledge of the risks associated with them and ensure that your organization is able to make informed decisions when using UAS. 

Recommendation: The E-ISAC recommends members review the updated policy for awareness. 

The E-ISAC is providing this bulletin for situational awareness. If further information becomes available, it will be added as an update to this post.

Details: Recent open source articles have noted a few incidents resulting in power outages in Zimbabwe, Bangladesh, and Venezuela. While these are international incidents, they are of interest as the tactics could be an inspiration to those who wish to sabotage the electric grid in North America as well as being a reminder of that damage that can be done.

 

Bangladesh: In an apparent sabotage effort, nine electric meters caught on fire in four separate locations in Bagerhat. All fires occurred simultaneously after midnight within a quarter of a kilometer from each other. The fire was not due to any short circuit or fault.

Zimbabwe: Transformer vandalism and theft has resulted in power outages over the past week, particularly in Marlborough. Residents have noted outage has affected business, lack of water, reduced ability to use facilities, and other health hazards. The Zimbabwe Electricity Supply Authority (ZESA) noted that it takes about five months to replace transformers due to lack of funds. Over 2,200 transformers have been stolen across the country.
