--Connecticut School District Hit with Second Ransomware Attack

(September 13, 2019)

Wolcott Public Schools is recovering from yet another ransomware attack. The Western Connecticut school district was hit with a ransomware attack in June of this year. The attackers demanded a ransom of $12,000; it has not been paid. When suspicious activity was noted on September 4, the school district shut down its entire system as a precautionary measure.

--Baltimore Lost Data in Ransomware Attack

(September 11, 2019)

Baltimore's city auditor said that, due to the ransomware attack that hit city systems in May of this year, the city's information technology department lost performance data, which was stored locally and was not backed up. This is the first admission of lost data related to this attack.


[Editor Comments]


[Neely] The city won't know the full scope of lost data until recovery efforts are complete. Lost data will include not only files not backed up, but also, transactions that cannot be rolled forward or recreated. Beyond reviewing your IT assets to ensure appropriate backups are in place regularly, also document and revalidate areas where the risk of data loss has been accepted.


[Honan] I would encourage anyone with responsibility in their organisation to take these examples of ransomware attacks as a template to run a desktop exercise in their company to identify and determine how well your organisation could cope in a similar situation

--Albany Ransomware Clean-up Costs

(September 13, 2019)

The amount of money the city of Albany, New York, spent on recovery efforts after a ransomware attack in March is unclear. A request made under New York state's Freedom of Information Law for information about certain costs was met with a document breaking down costs for hardware and software investments, credit monitoring services, and professional services, which totaled just over $160,000. The mayor has said publicly that the city has spent more than $300,000, but has not provided a breakdown of those costs. The city has not disclosed the amount the attackers demanded.

--US Consumer Financial Protection Bureau Proposed Rule Would Require Consumers to Click on Links from Unfamiliar eMail Addresses

(August 9, 12, & 23, 2019)

The US Consumer Financial Protection Bureau has proposed a rule that would require people to click on links in unfamiliar email messages. The rule would allow debt collectors to send a "validation notice," the initial contact that debt collectors are required to send, via email or text message, requiring that the recipient click on a link provided to see the notice.  A recent court case could spell troubles for the proposed rule. In August, a US federal appeals court ruled that email does not qualify as "communication" as defined by the Fair Debt Collection Practices Act. 


[Editor Comments]


[Murray] Here was me thinking that clicking on "links in unfamiliar email messages" often resulted in system compromise.  This seems to be a case in which the solution to one problem aggravates another. 

 

[Neely] Currently debt collectors are required to validate/disclose the debt via mail, and must obtain prior consent from the consumer for electronic communications. Collectors argue they want to use secure email and document delivery platforms to speed and improve the process. They also claim debtors don't want an email that indicates debit collection in the sender or subject. We educate users not to click links or attachments from unknown senders. Even with needed transparency, out-of-band verification and consent to use electronic processes, many debtors are disinclined to respond by the time their issues are turned over to a collection agency.

--Who is Responsible for Internet Architecture Security?

(September 10 & 11, 2019)

Witnesses at a September 10 House Armed Services Committee Hearing on Securing the Nation's Internet Architecture included Jeanette Manfra, Assistant Director for Cybersecurity at the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency; Diane Rinaldo, Acting Assistant Secretary and Administrator at the Department of Commerce's National telecommunications and Information Administration; and Ed Wilson. Deputy Assistant Secretary for Cyber Policy at the Department of Defense's Office of the Undersecretary of Defense for Policy. Committee Chairman Jim Langevin (D-Rhode Island) noted that while various agencies have laid claim to distinct aspects of cyber policy, there is no single entity that has responsibility for the security of Internet architecture and said, "I'm very worried that by carving out discrete lanes in the road, there are seams left unaddressed in the middle, and I'm concerned that internet architecture security is one of those seam issues."

--US Treasury Sanctions North Korean Hackers

(September 13, 2019)

The US Department of the Treasury's Office of Foreign Assets Control (OFAC) has placed three North Korean hacking groups on a sanctions list. OFAC says the groups are controlled by North Korea's government, and that one of them is responsible for the 2017 WannaCry attack and the 2014 attack against Sony Pictures. The sanctions will make it easier for OFAC to seize any of the groups' assets that are in US financial institutions.


[Editor Comments]


[Neely] While these sanctions make it far simpler and faster for OFAC to seize assets, these North Korean groups have targets well beyond the US. Downsizing US activities may not have a large impact on their viability. Equivalent actions in other target countries are also needed.

--Court: Scraping Data from Public Sites Does Not Violate CFAA

(September 9, 2019)

The Ninth US Circuit Court of Appeals has upheld a lower court ruling that a company that scrapes data from public LinkedIn accounts is not in violation of the Computer Fraud and Abuse Act. LinkedIn sent a cease and desist order to HiQ, which was scraping data from the public profiles for its data analytics services, in 2017. HiQ sued, seeking a ruling that not only said the activity did not violate CFAA, but also prohibiting LinkedIn from interfering in its activity. The court found in HiQ's favor in 2017, and the Appeals Court agreed with that ruling, noting that the CFAA does not apply to data that are publicly available.    


[Editor Comments]


[Neely] While information openly published can't be recalled once captured, it's a still good idea to check what information you are publicly sharing on the Web. Not just from LinkedIn and other social media sites, but also sites related to personal and professional associations. Then take steps to update or remove unwanted information from those sites, ultimately keeping the desired data at the top of data collecting sites cache.

--Pen Test Gone Wrong

(September 13 & 16, 2019)

Two employees of a company that was hired to test the security of electronic court records in Dallas County, Iowa, were arrested on burglary charges for physically breaking into the Dallas County Courthouse in the early hours of Wednesday, September 11. The officials who hired the company did not inform county officials of the penetration testing efforts. In a statement, Iowa's state court administration (SCA) said it had hired Coalfire, a "cybersecurity advisor", "to attempt unauthorized access to court records through various means to learn of any potential vulnerabilities. SCA did not intend, or anticipate, those efforts to include the forced entry into a building."


[Editor Comments]


[Skoudis] Of course, it's absolutely vital to have a detailed scope document and rules of engagement before beginning any penetration test.  The scope should clearly cover every aspect of the test, including networks, hosts, social engineering, wireless, and ESPECIALLY any physical elements associated with the project.  That said, given the high level of experience of the pen test company involved here, as well as the local players, I suspect that local politics may be involved in this particular situation.

 

[Neely] In addition to Ed's comments, having both your point of contact and employer apprised and aware of tester activities to provide needed support is crucial.

(September 16, 2019)

Police in Israel have arrested several people who hold high-ranking positions at subsidiaries of Ability, a company that makes and sells tools for intercepting mobile device communications to law enforcement agencies around the world. The company's export license was suspended in March of this year; there is speculation that the arrests came in response to the company continuing to sell its products outside the country.

--Someone is Fraudulently Buying Certificates and Reselling Them

(September 16, 2019)

Researchers have found evidence that criminals impersonating legitimate entities have been buying digital certificates and reselling them on the black market. Some of the fraudulently obtained certificates have been used to spread malware.


[Editor Comments]


[Ullrich] Digitally signed malware and malicious websites with valid TLS certificates are normal at this point. Some security awareness training has associated signed software with harmless/valid software. But certificates do not attest to the software being not malicious. Thresholds to obtain certificates are low. As a best case, certificates identify the author of the software.

--Brokerage Ordered to Pay $1.5 Million in Sanctions After Breach

(September 12 & 13, 2019)

A Chicago futures brokerage will pay $1.5 million in sanctions after thieves breached its email system, accessed customer accounts, and stole $1 million from one of those accounts. A February 2018 phishing attack against Phillip Capital Inc. successfully targeted the firm's IT department. The US Commodity Futures Trading Commission (CFTC) imposed the sanction in an order, designating $500,000 as a penalty, and $1 million as restitution. The CFTC found that Phillip Capital "failed to disclose the cyber breach to its customers in a timely manner ... [and] failed to supervise its employees with respect to cybersecurity policy and procedures."

--UK Environmental Agencies Lost More than 500 Devices

(September 16, 2019)

Information obtained through Freedom of Information requests revealed that two UK government agencies that focus on environmental issues cannot account for 540 mobile digital devices over the past three financial years. More than three-quarters of the lost devices are phones. In all, 94 laptops and 21 tablet computers have also been reported missing.


[Editor Comments]


[Neely] Make sure that mobile devices are configured to minimize risk of data loss if they are misplaced, stolen or otherwise missing. Finding devices by tracking emissions while in vehicles or other locations is becoming a popular technique used by thieves. Implementing full-device encryption, robust authentication, remote locating and wiping capabilities can protect against data loss, also investigate replacing sleep mode with hibernate to both clear memory and reduce device emissions. Support these actions with clear policy and education so users know what is expected to protect these devices.
