Matt Wiseman of Cisco Talos discovered these vulnerabilities. Blog by Jon Munshaw.  Cisco Talos recently discovered several vulnerabilities in the Abode Systems iota All-In-One Security Kit. This kit includes a main security camera and hub that can alert users of unwanted movement in their homes. It also includes several motion sensors that can be attached to windows and doors.   The devices communicate with the user via a website or app on their mobile device and can connect to smart hubs like Google Home, Amazon Alexa and Apple Homekit.  The vulnerabilities Talos discovered could lead to a variety of conditions, including providing attackers with the ability to change users’ login passwords, inject code onto the device, manipulate sensitive device configurations, and cause the system to shut down. The devices contain several format string injection vulnerabilities in various functions of its software that could lead to memory corruption, information disclosure and a denial of servic...

By Abhishek Singh. BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets.   A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge.   Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit.   Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat ...

There are many ways to approach this growing threat, but here's why Talos feels intent-based protection is the best.

Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Oct. 7 and Oct. 14. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats. As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net. For each threat described below, this blog post only lists 25...

Cisco Talos is well-known for its work in spotting and defeating fake news, disinformation and misinformation. And state-sponsored actors, unwitting social media users and even direct government agencies have played a part in spreading fake news during Russia's invasion of Ukraine.  In this video, we'll look at a few examples of what essentially equates to propaganda spreading across social media, leading to false stories, headlines, posts and the continued degradation of the meaning of "truth."
