--Insurance Companies See Increasing Numbers of Ransomware Claims

(October 25, 2019)

The number of ransomware attacks and the amounts the hackers are demanding are both increasing. Insurance companies are seeing an increase in ransomware-related claims. Globally, insurers collected between $7 billion and $8 billion in cyberinsurance premiums in 2018.

--Johannesburg City Data Held for Ransom

(October 25, 2019)

The computer network of the city of Johannesburg, South Africa, was hit with a cyberattack last week. The files on the city's network are not encrypted, but the hackers have threatened to dump data they stole on the Internet unless they are paid. Shortly after receiving the ransom demand, Johannesburg shut down its website, e-services, and billing system. This is the second major cyberattack Johannesburg has faced in the past several months. In what appears to be an unrelated incident, several banks in Johannesburg have been fending off distributed denial-of-service (DDoS) attacks.

--Illinois Computer Repair Shop Worker is a Wizard at Cracking Ransomware

(October 28, 2019)

Michael Gillespie has cracked more than 100 different strains of ransomware and provided decryption tools at no cost to people whose machines have been infected. Gillespie is averse to paying ransom, not only because the payments could be funding terrorist activity, but also because payment encourages the attackers to continue infecting systems.


[Editor Comments]


[Neely] Having access to the decryption keys or access to a resource like Gillespie to obtain them is a key part of the payment decision. This needs to be coupled with an honest assessment of recovery capabilities to ensure success as well as management support.

--Inspector General: US Social Security Administration Let Critical Flaws Go Unfixed for More Than a Year

(October 28, 2019)

According to a summary of an audit report from the US Social Security Administration (SSA) Office of Inspector General (OIG), the SSA neglected to address known vulnerabilities in its systems for more than a year. Critical vulnerabilities detected in a 2018 audit were still percent in the 2019 audit. The report also found unauthorized software on SSA systems.


[Editor Comments]


[Pescatore] Not much information is available on this one, but SSA has a very good track record over the years of  protecting their systems. They have been proactive but have also done well in not repeating the same mistakes when something does go wrong. Let's hope that is the case here as well.

--UniCredit Data Breach Compromised Three Million Customer Records

(October 28, 2019)

Italian banking and financial services company UniCredit has acknowledged that a data breach affected the information of three million of its customers. UniCredit has customers around the world, but this breach affected just Italian customers. This breach is the third data security incident UniCredit has experienced since 2016.

--US Federal General Schedule System Hobbles Cyber Reskilling Job Placement Efforts

(October 28, 2019)

The US cyber reskilling program is running into issues with placing the newly-trained employees in positions to use their new skills because of the government's General Schedule employment system. An Office of Management and Budget (OMB) official said of the system, "It's not agile and it's not responsive to the needs of the 21st century."


[Editor Comments]


[Neely] In addition to staff obtaining updated skills, management support is needed to place them appropriately to use those skills and creative non-monetary means may be needed to retain these workers.

--Google Will Replace Bricked Devices

(October 25, 2019)

Google says it will replace Google Home and Mini devices that were rendered useless by a recent automatic firmware update. All devices affected by the update will be replaced, regardless of their warranty status. Google also plans to roll out a fix to prevent more devices from becoming bricked.


[Editor Comments]


[Neely] Unlike traditional IT where updates are pulled or scheduled, these updates are made without user interaction. While it is commendable that updates are being pushed rapidly for these IoT devices, that Google is replacing those that were bricked,and that they are raising the bar on their SQA processes, consider these as third-party managed computers on your network and provide corresponding segmentation to offset that risk.

--Canada and Independent Security Researchers (Podcast)

(October 25, 2019)

A Canadian college student found a vulnerability in a smart doorbell. When he contacted the company, he asked to disclose the flaw sooner than 90 days because the device had been discontinued before he found the flaw. The company threatened legal action. The student contacted the Canadian Internet Policy and Public Interest Clinic (CIPPIC), which helped convince the company to drop its threats. A CIPPIC attorney noted that Canada has a lack of clear legal precedent in the area of security research, which gives companies and government entities room to push back against the researchers.

--Man Who Rented Car Months Ago Still Has Remote Access to Doors, Engine

(October 28, 2019)

A man who rented a car in May connected it to the FordPass app that lets drivers remotely start and stop the vehicle's engine, lock and unlock its doors, and track its location. Masamba Sinclair returned the rental car months ago and other people have since rented it, but the app still allows him control over the vehicle. Both Ford and the rental company have been contacted, but neither has taken steps to remove the Sinclair's access to the vehicle.


[Editor Comments]

 

[Ullrich] This is an issue with many modern cars that are linked to mobile apps. There is often no clear method to "reset" the authentication tokens handed to these apps. This has been used in a few cases to steal high end rental cars, but it has also been an issue for used cars. Even if the prior owner isn't able to open the doors, these apps sometimes allow the prior owner to still track the location of the car. Disconnecting these applications is sometimes not possible at all, or has to be done at a dealership. There is no simple "factory reset" for some cars.


[Neely] My latest rental car agreement said I was on the hook for unpairing devices paired during my use. Ideally rental car providers need to incorporate resetting the car between rentals. The pressure to turn vehicles quickly may prevent this so user prudence is required.


[Pescatore] This is a good area to update in executive and employee security briefings. Rental cars, hotel room TVs, AirBNB rental houses, etc. all now have "apps" running in them in a number of devices that let you login to your personal Netflix, YouTube, Facebook, home video doorbell/smart thermostat etc. accounts - greatly increasing the probability that both sensitive personal information is left behind as well as accounts being left open and unauthorized access or password changes happening afterwards.
