RANSOMWARE AT THE TOP OF THE NEWS


--Ransomware Operators Publish Data Allegedly Stolen from LG, Xerox

(August 4, 2020)

Maze ransomware operators have published data they claim to have taken from internal networks at LG and Xerox after the companies declined to pay a ransom. In a June email exchange with ZDNet, Maze operators say they did not launch ransomware on LG's network, but only exfiltrated data.


[Editor Comments]


[Neely] Both systems ran Citrix ADC servers, vulnerable to CVE-2019-19781, which has been characterized as a favorite entry point for Maze Operators. Keeping your boundary and remote access devices patched, expeditiously, is critical with today's threat environment. Verify you can monitor and alert on exfiltration of data, including tuning and testing. Also, when considering breached data, remember to include assessing loss of intellectual property. Too often, the review is of customer or employee personal information.

ZDNet: Ransomware gang publishes tens of GBs of internal data from LG and Xerox

https://www.zdnet.com/article/ransomware-gang-publishes-tens-of-gbs-of-internal-data-from-lg-and-xerox/

 

--Blackbaud Paid Ransomware Demand

(August 3, 2020)

Blackbaud's CEO says the company "discovered and stopped a sophisticated attempted ransomware attack." Blackbaud paid the ransomware demand in May 2020; the attack was publicly disclosed in July. Blackbaud provides customer relationship management (CRM) software for colleges and universities, non-profit groups, and others.   


[Editor Comments]


[Neely] In this issue we have several articles where the ransom was paid. Back in October, the FBI published updated guidance on payment (https://www.ic3.gov/media/2019/191002.aspx) acknowledging that there are cases where companies will pay. With exfiltrated data being published, payment is vastly incentivized. Beyond payment, ensure that adequate steps are taken to prevent recurrence as well as timely notification of the incident, status, and resolution to affected parties to allow them to take appropriate actions, and to include required breach notifications to regulators and customers.

https://www.theregister.com/2020/08/03/blackbaud_glosses_over_ransomware_payoff/

 
 

--Bleeping Computer: Garmin Paid Ransomware Demand

(August 3, 2020)

According to a report in Bleeping Computer, Garmin received the WastedLocker ransomware encryption key on July 25, two days after its network was hit with the malware. While it is not known how much Garmin paid the WastedLocker operators, the initial demand was reportedly $10 million. Bleeping Computer obtained "access to an executable created by the Garmin IT department to decrypt a workstation and then install a variety of security software on the machine."


[Editor Comments]


[Pescatore] Dealing with the Covid virus has reinforced the importance of data-based decision making. There are many good reasons not to pay ransomware demands but there is not good data to support when/if it does make financial sense. One factor that can swing the decision: if your company has extortion insurance and the language in that policy covers/does not exclude ransomware, management may find that the cost of paying off is reduced enough to be well below the business disruption costs. In next week's NewsBites DrillDown I'll publish a deeper dive into the issues with a few example data sets.

--US Travel Agency CWT Reportedly Paid $4.5M Ransomware Demand

(July 31, 2020)

Corporate travel agency CWT, formerly known as Carlson Wagonlit Travel) has confirmed that its network was shut down due to a ransomware attack in late July. The company reportedly paid $4.5 million to regain access to its encrypted data. The strain of ransomware used in the attack appears to be Ragnar Locker.

--Texas School District Will Pay Ransomware Demand

(July 31, 2020)

The Athens (Texas) Independent School District (ISD) will pay $50,000 to ransomware operators to regain access to the data in its servers that have been encrypted. The district's board of trustees voted to pay the ransom, which will be covered by insurance. The attack will postpone the start of the school year by at least a week.

--No More Ransom Website Helps Ransomware Victims

(July 27, 2020)

The No More Ransom decryption tool repository was established four years ago this month. No More Ransom offers free tools to decrypt 140 strains of ransomware. "The website is an initiative by the National High Tech Crime Unit of the Netherlands' police, Europol's European Cybercrime Centre, Kaspersky and McAfee with the goal to help victims of ransomware retrieve their encrypted data without having to pay the criminals."


[Editor Comments]


[Neely] This site doesn't eliminate the need for good disconnected differential backups; it provides a potential resource where you could retrieve the decryption key for your particular ransomware attack. Be sure to take steps to fix and verify that the entry point is closed to prevent recurrence first. This also doesn't eliminate the need to respond to ransom demands for exfiltrated and published content.

--Three Arrested in Connection With the Twitter Hack

(July 31 & August 1, 2020)

Authorities have arrested and charged three people in connection with the July 15 Twitter hack that took over several high-profile accounts and used them in a Bitcoin fraud scheme. The attackers allegedly used social engineering to gain access to internal Twitter tools. One of the suspects, a 17-year-old, faces 30 felony charges and will be tried as an adult.


[Editor Comments]


[Neely] With enhanced working from home, there are more opportunities for accessing malicious content from outside the company perimeter. Take a pause to identify and resolve gaps. Ask whether your users are using personal phones or the corporate softphone with its VoIP firewall and associated protections? Are users able to browse to disallowed sites normally blocked by NGFW or outbound proxy rules? Even with remote or virtual desktops, understand what work is permitted off those systems as well as data interchange capabilities between the remote and local systems. Take steps to minimize data exchange to prevent paths for inbound malfeasance.

--FastPOS Author Pleads Guilty to RICO Conspiracy

(August 1 & 3, 2020)

A Moldovan citizen has pleaded guilty to RICO (Racketeer Influenced and Corrupt Organizations) conspiracy in a Nevada courtroom for his role in the Infraud cybercriminal organization. In a plea agreement, Valerian Chiochiu admitted to creating malware known as FastPOS, which was designed to facilitate payment card data theft.

--BootHole Fix is Causing Problems

(July 31, 2020)

Users are urged to take steps to mitigate the issue. Linux distributions have released fixes for the GNU GRUB2 bootloader vulnerability, a.k.a. BootHole. However, some users are reporting that these fixes are causing problems themselves. Users are rebooting booting and dual-booting issues in Debian, Ubuntu, Red Hat, CentOS, and Fedora. The US National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have issued advisories that include suggestions for mitigating the BootHole vulnerability.

--Update Available for WordPress Newsletter Plugin Flaws

(August 3, 2020)

Flaws in the Newsletter plugin for WordPress can be exploited to establish backdoors, create admin accounts, and possibly take control of vulnerable sites. The plugin's developers have released an updated version, Newsletter 6.8.3, which addresses these vulnerabilities.


[Editor Comments]


[Neely] This flaw includes a PHP Object Injection as well as a reflected Cross-Site Scripting (XSS) vulnerability. The good news is that the plugin author provided an update the day after the vulnerability was disclosed. The bad news is you still need to update your plugins, or make sure you have an application firewall rule to detect attempted exploitation. While Wordfence premium has the firewall rule, and it will be released to the free version users on August 14th, don't wait to update.
