--Managed Service Providers Are Being Used to Spread Ransomware

(October 30 & 31, 2019)

According to a report from Armor, at least 13 managed service providers (MSPs) were used to spread ransomware so far in 2019. Companies that use MSPs generally install software that allows the MSP remote access to their systems; attackers can exploit the remote access to push the ransomware to the organizations' networks. The concurrent ransomware attacks in Texas earlier this year were launched through their shared MSP.


[Editor Comments]


[Ullrich] Supply chain security is a big topic these days, and MSPs are part of your supply chain. Your systems are only as secure as the weakest entity that has access to it. For ransomware distributers, MSPs are a gold mine in that they provide simple access to numerous networks.


[Neely] If the MSP has remote access to your network, they likely have access to multiple companies' networks which makes this a different risk profile than a remote branch or hosting center.

--Malware Found on Indian Nuclear Plant Network

(October 30, 2019)

The Nuclear Power Corporation of India Ltd. (NPCIL) detected malware on its network earlier this year, but noted that the affected computer was part of the plant's administrative network and isolated from the critical internal network." NPCIL learned of the infection from the government's cybersecurity agency in early September. Dtrack, the malware that was found on the computer, shares some code elements with malware used by a North Korean hacking group. (Please note that the WSJ story is behind a paywall.)


[Editor Comments]


[Neely] While this malware isn't on the control network, data often move between control networks and external networks which may provide a path. One-way links and media screening systems or kiosks can reduce the risks, but a full understanding of data flows is required for success.

 

[Murray] This appears to have been a target identification attack that failed at being sufficiently stealthy. All such targets should be on the alert for such attacks.

--Utah Renewable Energy Provider Hit with Cyberattack in March

(October 31, 2019)

sPower, a Utah renewable energy company, was hit with a cyberattack in March of this year, causing it to lose communication connections with several of its solar and wind power generation sites for brief periods of time. The March 5 attack is believed to be the first recorded cyberincident that caused a disruption to the power industry. The attackers exploited a known vulnerability in a Cisco firewall to create a denial-of-service condition. sPower has since patched the affected devices. E&E News first reported the incident in April. The additional information in the more recent stories was obtained through a Freedom of Information Act (FoIA) request.

--Scammers Trying to Steal Office 365 Credentials with Fake Voice Mail Messages

(October 30 & 31, 2019)

Researchers at McAfee have detected a phishing campaign that uses voicemail messages to try to trick recipients into disclosing their Office365 account access credentials. Targeted individuals received email messages telling them they had missed a phone call and asking them to log into their Office365 account to retrieve the message.


[Editor Comments]


[Neely] This is a good time to remind users of legitimate password recovery options to help them make good choices for these sorts of emails. Also make sure that your email service anti-phishing and anti-malware services are enabled to block or quarantine these types of attachments.

--Hackers Infect QNAP NAS Devices with Malware

(October 31, 2019)

Thousands of QNAP network-attached storage (NAS) devices have been infected with malware. The National Cyber Security Centre of Finland (NCSC-FI) detected the malware, known as QSnatch, last week. The malware's capabilities include preventing firmware updates, preventing a malware removal app from running, and stealing usernames and passwords. Currently the only confirmed way to remove QSnatch from infected devices is to do a factory reset.


[Editor Comments]


[Ullrich] Never expose a networked storage device to the Internet. These devices are notoriously vulnerable due to the numerous poorly coded web applications installed on them. And of course, users aren't helping with easy to guess passwords. Exposing them internally is still a risk, and even though some manufacturers advertise them for public file sharing, you are probably better off using a cloud service for that. This does not just apply to QNAP, but to this type of device in general.

--Persistent xHelper Malware Infects Android Devices

(October 29, 2019)

A Trojan dropper that is being called xHelper infects Android devices and reinstalls itself after it is removed and even after factory resets. xHelper has infected more than 45,000 Android devices in the last six months.


[Editor Comments]


[Neely] Until the mechanism for clearing the malware out of persistent storage is discovered, affected devices should be replaced and not reused.


[Murray] While it is possible for the savvy to operate Android devices safely, they are not recommended for the young, the elderly, or the otherwise naive.

--Facebook Sues NSO Group Alleging It Used WhatsApp Accounts to Infect Phones with Spyware

(October 29, 30, & 31, 2019)

Facebook has filed a lawsuit against NSO Group, alleging that the company created WhatsApp accounts and used them to make calls to their targets, infecting them with Pegasus spyware. The alleged targets include lawyers, journalists, human rights activists, and political dissidents. (Please note that the WSJ story is behind a paywall.)


[Editor Comments]


[Pescatore] Many different issues in this item but I'll focus on this since there are lots of claims yet to be validated on who did what: supply chains are complex networks, not simple chains. Simplistically, to estimate the reliability of a chain you multiply all the probabilities of success of each link and come up with an estimate of overall reliability or risk. In a network, you have to do that for *every* path and find the highest risk path. Facebook left a vulnerability in WhatsApp that may have allowed WhatsApp to be used to impact your company or your customers and I doubt Facebook or WhatsApp was listed as a supplier.

 

[Murray] Users of device-to-device encryption should be aware of its limitation, i.e., the message is in the clear on the end devices. Prefer person-to-person encryption for "life and death" applications. NSO Group is a rogue enterprise operating under the protection of a nation state, with the consent of other states, and with dodgy customers.

--More Details About Coalfire PenTest Arrests

(October 29 & 30, 2019)

In September, two employees of Coalfire, a Colorado-based security firm, were arrested inside the Dallas County (Iowa) Courthouse while conducting a penetration test. The team entered the building in the middle of the night, deliberately tripped the alarm to test law enforcement response time, and waited for law enforcement to arrive. Coalfire had been hired by the Iowa State Judicial Branch to conduct the testing, and the employees were arrested by the Dallas County sheriff. In early October, the chief justice of the Iowa Supreme Court publicly apologized for the situation, acknowledging that "Mistakes were made [and that they] are doing everything possible to correct those mistakes, be accountable for the mistakes and to make sure they never, ever occur again." The two employees initially faced charges of felony burglary; on October 25, the charges were reduced to criminal trespass. Coalfire CEO Tom McAndrew has issued a statement saying that he "will continue to support and aggressively pursue all avenues to ensure that all charges are dropped and their criminal records are purged of any wrongdoing," and that "It is unacceptable that they are now pawns in the dispute between the state and the county related to governance of the court buildings."


[Editor Comments]


[Skoudis] This is really an unfortunate situation fueled by local politics. It underscores the absolute necessity of penetration testers having all their permission forms and rules of engagement signed in advance. Furthermore, it's vital to ask target personnel about various stake-holders and third parties associated with the target environment. It sure sounds like the Coalfire team did all of that here, and that vital prep work will make all the difference in how this ultimately turns out.

--Las Cruces School District Ransomware Attack

(October 29, 2019)

The Las Cruces (New Mexico) public school district was the victim of a ransomware attack. When officials became aware of the malware on some district servers on the morning of Tuesday, October 29, they ordered a district-wide shutdown to contain the infection.


[Editor Comments]


[Neely] Segmenting traffic to isolate systems that don't need to connect would allow containment without taking the whole network offline. Also consider blocking outbound attachments from a compromised system in your disaster recovery planning.
