057| Dark Web: The Good, the Bad, and the Ugly

After data breaches and ransomware attacks, we often hear that customer information was leaked to the dark web. This obviously can have serious implications for both companies and individuals, but for many of us, the dark web is as mysterious as it sounds. So what is the dark web all about, and what's happening there? How does it affect companies and regular people? F-Secure's Laura Kankaala and Elias Koivula join the show to help to help demystify the topic. Links: Episode 57 transcript (Cyber Security Sauna)

BlackBerry's popular operating system for medical devices affected by critical vulnerabilities, drawing fed warnings

A critical set of software flaws first revealed in April also affects code made by BlackBerry that is used in countless devices in the medical, automotive and energy sectors, the technology vendor confirmed on Tuesday. A hacker who exploits the so-called BadAlloc software vulnerabilities, which Microsoft researchers uncovered, could cause devices running the software to crash. In BlackBerry’s case, the attacker would need to first gain access to a targeted network and then go after devices that are exposed to the internet. The affected software is BlackBerry’s QNX Real-Time Operating System, a suite of software that manages data across a network. It’s unclear just how many devices are running the affected BlackBerry software. The firm said last year that its QNX software was embedded in more than 175 million cars alone. A BlackBerry spokesperson did not immediately respond to a request for comment. “These vulnerabilities may introduce risks for certain […] The post BlackBerry's popular operating system for medical devices affected by critical vulnerabilities, drawing fed warnings appeared first on CyberScoop.

Japan's Tokio Marine is the latest insurer to be victimized by ransomware

Ransomware struck Japan’s largest property and casualty insurer, Tokio Marine Holdings, at its Singapore branch, the company disclosed on Monday. Tokio Marine, which has a U.S. division and offers a cyber insurance product, said it did not have any immediate indication that any customer information was breached. Such data could be a smorgasbord for hackers who would use the data to extort victims based on their coverage amounts. It’s at least the third major insurer to disclose a ransomware attack in recent months, following CNA and AXA. And it’s the second insurer just this week, with Ryan Specialty Group — fresh off launching an initial public offering — to disclose a cyber incident. Cyber insurers have, of late, taken to asking more detailed questions about policyholders’ cybersecurity safeguards as a condition for providing coverage. But the spate of recent successful attacks suggests that insurers, too, might need to step up […] The post Japan's Tokio Marine is the latest insurer to be victimized by ransomware appeared first on CyberScoop.

Suspected Russian operatives tried to stir far-right outrage about COVID-19 on 4chan

Operators of an apparent Russian propaganda campaign shared coronavirus disinformation in an effort to influence the American far-right, according to a report out Tuesday by cybersecurity firm Recorded Future.  The findings are included in a new report shedding light on a long-running Russian propaganda campaign known as Operation Secondary Infektion. The years-long campaign has used regional European websites, forged documents and throwaway accounts to further Russia’s political agenda in Europe. Secondary Infektion is perhaps best known for spreading disinformation through small, local websites, then promoting fabricated narratives on social media, with mixed success. Secondary Infektion promotes narratives in line with Russia’s political agenda in Europe, leading researchers to believe the group supports Russia’s intelligence apparatus. Since 2014 the group has staged a number of campaigns, including using fake tweets from accounts like Sen. Marco Rubio, R-Fla. to spread a false narrative that British citizens planned to assassinate Prime Minister Boris […] The post Suspected Russian operatives tried to stir far-right outrage about COVID-19 on 4chan appeared first on CyberScoop.

Mandiant, CISA urge ThroughTrek customers to fix software bug in millions of baby monitors, cameras

A flaw in software used by millions of smart home devices could allow hackers to intercept audio and video data on equipment such as baby monitors and web cameras, security researchers said Tuesday. The vulnerability is in a software protocol made by Taiwanese internet of things (IoT) vendor ThroughTek, which has customers including the Chinese electronics giant Xiaomi. ThroughTek says 83 million devices made by other brands, such as the camera vendor Wyze, run its software. To exploit the flaw, an attacker would need “comprehensive knowledge” of the software protocol, and to obtain unique identifiers used by the targeted device, according to Mandiant, a division of FireEye, which discovered the issue. With that access, a hacker could communicate with devices remotely, potentially leading to follow-on hacks. The Department of Homeland Security plans to issue a public advisory to raise awareness of the security issue, Mandiant said. Yi-Ching Chen, an employee […] The post Mandiant, CISA urge ThroughTrek customers to fix software bug in millions of baby monitors, cameras appeared first on CyberScoop. (CyberScoop)
