DOJ Charges North Korean in Sony Hack, Wanna Cry Attack

(September 6, 2018)

The US Department of Justice (DOJ) has charged Park Jin Hyok, a North Korean computer programmer, in the 2014 attack against Sony Pictures, a 2016 theft from Bangladesh Bank, and the 2017 Wanna Cry malware attack. The complaint alleges that Park carried out the attack against Sony Pictures on behalf of the North Korean government; it also links Park to the Lazarus Group, which is believed to be involved in the Wanna Cry attack and a Bangladesh Bank theft.

Tesla Will Reflash Car Firmware for Vulnerability Testers

(September 6, 2018)

Tesla has reiterated that researchers are permitted to hack its cars without voiding the vehicles warranty or facing legal liability. Tesla says it will restore firmware and operating systems on cars that have undergone and have become incapacitated by testing, with some conditions: the researcher and the vehicle must be registered and approved as part of Teslas vulnerability reporting program. 


[Editor Comments]


[Pescatore] Kudos to Tesla for doing the right thing. Would you buy a car from a manufacturer who said, We are not going to allow Consumer Reports magazine to test our cars, because all that swerving around cones will void the warranty? Consumers demand safety features in the carscar advertisements seem to equally emphasize safety and style. We need to convince consumers that an important part of safety is high quality software in the cars they buy.


[Neely] Before signing up for the program, researchers need to note the limits to the number of times the vehicle will be re-flashed and that the researcher will bear the expense of getting the car to a service facility.

--Windows Zero-Day: Advanced Local Procedure Call (ALPC)

(September 5 & 6, 2018)

An unpatched flaw in Windows Advanced Local Procedure Call (ALPC) is being actively exploited. The vulnerability was first disclosed on August 27, 2018. The issue is due to the ALPC function not properly checking user permissions when interacting with files in the Windows Task Scheduler folder in Windows OS versions later than Windows 7.

Schneider Controller Vulnerability

(September 6, 2018)

A vulnerability in Schneider Electric Modicon controllers could be exploited to remotely reboot the device, which could prevent them from communicating with the other parts of the industrial control system (ICS) network. The issue is an improper check for unusual or exceptional conditions. The flaw affects Modicon M221 controllers prior to firmware versions 1.6.2.0.

House Approves DHS Supply Chain Security Bill

(September 5, 2018)

The US House of Representatives have approved a bill that would allow the Department of Homeland Security (DHS) to exclude certain contractors from conducting business with the government. The Securing the Homeland Security Supply Chain Act of 2018 requires that DHS notify contractors of the decision to ban them in most cases, but also allows the agency to impose an immediate ban in the interest of national security. The bill does not yet have a companion bill in the Senate.

Thousands of MikroTik Routers Unpatched Against Flaw Disclosed in April

(September 4 & 5, 2018)

Thousands of unpatched MirkoTik routers have been compromised with malware that sends network traffic data to a control server. MikroTik released a fix for the vulnerability in April. More than 370,000 routers have not yet been patched for the flaw.


[Editor Comments]


[Neely] The attackers seem to be focusing on SNMP traffic, and as organizations often reuse community strings, compromise could have broad consequences. As the hack installs added jobs, a factory reset in addition to applying the patch is a good idea. More routers are supporting automatic firmware updates which can mitigate some of these risks.

Chrome 69 Includes Fix for Flaw That Could Be Exploited to Steal WiFi Credentials

(September 4 & 5, 2018)

Google has released Chrome 69. The most recent stable version of the browser addresses 40 vulnerabilities, including an issue that could be used to steal WiFi login credentials because older versions of the browser auto-filled usernames and passwords in HTTP logon forms.


[Editor Comments]


[Neely] This fix to Chrome puts it on-par with Firefox, Internet Explorer, Edge and Safari for auto-filling login information in HTTP forms. Exploiting the vulnerability relies on getting the victim on a spoofed WiFi using Karma and presenting an imitation captive portal page for the users router, which the browser will autofill. The primary mitigation is updating Chrome. Beyond that, enable HTTPS on your home router if it supports it, administer your home router over a wired connection, or if on Wi-Fi, make sure that youre really on your network before connecting to the admin page.

 

[Murray] It is difficult to understand as stable products that persistently issue fixes for tens of vulnerabilities at a time.

Open .git Directories Expose Site Source Code

(September 4 & 5, 2018)

Researcher Vladimir Smitka found nearly 400,000 web pages with open .git directories. The directories can expose database passwords, API keys, and other information that should not but which often is stored in the repository.


[Editor Comments]


[Williams] - This is a symptom of the larger problem of poorly audited permissions on directories accessible from the Internet. If you haven't audited your website for forced browsing attacks, the time to do so is now. With the increased attention on .git directories, expect to see an increase in attackers scanning for forced browsing vulnerabilities of all types.

 

[Neely] When deploying an application to your site, make sure that the .git directory is not available. Even without an index file and directory browsing disabled, well known files can still be retrieved, such as the list of commits in /.git/logs/HEAD. Verify the directory contents are not retrievable by attempting to access <web-site>/.git/HEAD.
