A team of cybersecurity researchers late last week disclosed the existence of 12 potentially severe security vulnerabilities, collectively named ' SweynTooth ,' affecting millions of Bluetooth-enabled wireless smart devices worldwide—and worryingly, a few of which haven't yet been patched. All SweynTooth flaws basically reside in the way software development kits (SDKs) used by multiple system-on-a-chip (SoC) have implemented Bluetooth Low Energy (BLE) wireless communication technology—powering at least 480 distinct products from several vendors including Samsung, FitBit and Xiaomi. According to the researchers, hackers in close physical proximity to vulnerable devices can abuse this vulnerability to remotely trigger deadlocks, crashes, and even bypass security in BLE products, allowing them to arbitrary read or write access to device's functions that are otherwise only allowed to be accessed by an authorized user. "As of today, SweynTooth vulnerabilities a...

The US Department of Justice (DoJ) and the Federal Bureau of Investigation (FBI) charged Huawei with racketeering and conspiring to steal trade secrets from six US firms, in a significant escalation of a lawsuit against the Chinese telecom giant that began last year. Accusing Huawei and its affiliates of "using fraud and deception to misappropriate sophisticated technology from US counterparts," the new charges allege the company of offering bonuses to employees who obtained "confidential information" from its competitors. The indictment adds to a list of two other charges filed by the US government last year, including violating US sanctions on Iran and stealing technology from T-Mobile — called Tappy — that's used to test smartphone durability. The development is the latest salvo fired by the Trump administration in its year-long fight against the networking equipment maker, which it deems a threat to national security. "The misappropriated ...

Google removed 500 malicious Chrome extensions from its Web Store after they found to inject malicious ads and siphon off user browsing data to servers under the control of attackers. These extensions were part of a malvertising and ad-fraud campaign that's been operating at least since January 2019, although evidence points out the possibility that the actor behind the scheme may have been active since 2017. The findings come as part of a joint investigation by security researcher Jamila Kaya and Cisco-owned Duo Security, which unearthed 70 Chrome Extensions with over 1.7 million installations. Upon sharing the discovery privately with Google, the company went on to identify 430 more problematic browser extensions, all of which have since been deactivated. "The prominence of malvertising as an attack vector will continue to rise as long as tracking-based advertising remains ubiquitous, and particularly if users remain underserved by protection mechanisms," sa...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

The realistic approach to security is that incidents occur. While ideally, the CISO would want to prevent all of them, in practice, some will succeed to a certain degree—making the ability to efficiently manage an incident response process a mandatory skill for any CISO. Moreover, apart from the management of the actual response process, the CISO must also be able to efficiently communicate the ongoing activities and status to the executive level. While the IR process is mostly technical, reporting to the organization's management should take place on a much higher level in order for the non-security -savvy executives to understand. To assist CISOs with these tasks, Cynet created the IR Management and Reporting PowerPoint template ( download here ), which apart from providing an actionable response framework, is also clear and intuitive for the executive level. Let's drill down on the two aspects of the template: IR Management The template was built on the SANS\...

Emotet, the notorious trojan behind a number of botnet-driven spam campaigns and ransomware attacks, has found a new attack vector: using already infected devices to identify new victims that are connected to nearby Wi-Fi networks. According to researchers at Binary Defense , the newly discovered Emotet sample leverages a "Wi-Fi spreader" module to scan Wi-Fi networks, and then attempts to infect devices that are connected to them. The cybersecurity firm said the Wi-Fi spreader has a timestamp of April 16, 2018, indicating the spreading behavior has been running "unnoticed" for close to two years until it was detected for the first time last month. The development marks an escalation of Emotet's capabilities, as networks in close physical proximity to the original victim are now susceptible to infection. How Does Emotet's Wi-Fi Spreader Module Work? The updated version of the malware works by leveraging an already compromised host to list all ...

A few hours after Adobe today released security updates for five of its widely-distributed software, Microsoft also issued its February 2020 Patch Tuesday edition with patches for a total of 99 new vulnerabilities. According to the advisories, 12 of the total issues patched by the tech giant this month are critical in severity, and the remaining 87 have been listed as important. Five of the bugs are listed as publicly known at the time of release, four of which are important in severity and one critical ( CVE-2020-0674 ) that is also listed as under active attack. Microsoft warned about this zero-day vulnerability in Internet Explorer (IE) browser last month when it released an advisory without releasing a patch for millions of its affected users. As explained previously, this flaw could allow a remote attacker to execute arbitrary code on targeted computers and take full control over them just by convincing victims into opening a maliciously crafted web page on the vulner...

Here comes the second 'Patch Tuesday' of this year. Adobe today released the latest security updates for five of its widely used software that patch a total of 42 newly discovered vulnerabilities, 35 of which are critical in severity. The first four of the total five affected software, all listed below, are vulnerable to at least one critical arbitrary code execution vulnerability that could allow attackers to take full control of vulnerable systems. Adobe Framemaker Adobe Acrobat and Reader Adobe Flash Player Adobe Digital Edition Adobe Experience Manager In brief, Adobe Framemaker for Windows, an advanced document processing software, contains 21 flaws, and all of them are critical buffer error, heap overflow, memory corruption, and out-of-bounds write issues, leading to code execution attacks. Adobe Acrobat and Reader for Windows and macOS also contain 12 similar critical code execution vulnerabilities, along with 3 other important information disclosure ...
