Security vulnerabilities uncovered in cloud-based pinyin keyboard apps could be exploited to reveal users' keystrokes to nefarious actors. The findings come from the Citizen Lab, which discovered weaknesses in eight of nine apps from vendors like Baidu, Honor, iFlytek, OPPO, Samsung, Tencent, Vivo, and Xiaomi. The only vendor whose keyboard app did not have any security shortcomings is that of Huawei's. The vulnerabilities could be exploited to "completely reveal the contents of users' keystrokes in transit," researchers Jeffrey Knockel, Mona Wang, and Zoë Reichert  said . The disclosure builds upon prior research from the interdisciplinary laboratory based at the University of Toronto, which identified  cryptographic flaws  in Tencent's Sogou Input Method last August. Collectively, it's estimated that close to one billion users are affected by this class of vulnerabilities, with Input Method Editors (IMEs) from Sogou, Baidu, and iFlytek accounting fo

Google on Monday rolled out out-of-band security patches to address a critical security flaw in its Chrome web browser that it said has been exploited in the wild. Tracked as  CVE-2023-4863 , the issue has been described as a case of  heap buffer overflow  that resides in the  WebP image format  that could result in arbitrary code execution or a crash. Apple Security Engineering and Architecture (SEAR) and the Citizen Lab at the University of Toronto's Munk School have been credited with discovering and reporting the flaw on September 6, 2023. The tech giant has yet to disclose additional details about the nature of the attacks, but noted that it's "aware that an exploit for CVE-2023-4863 exists in the wild." With the latest fix, Google has addressed a total of four zero-day vulnerabilities in Chrome since the start of the year - CVE-2023-2033  (CVSS score: 8.8) - Type Confusion in V8 CVE-2023-2136  (CVSS score: 9.6) - Integer overflow in Skia CVE-2023-3079

Shadow apps, a segment of Shadow IT, are SaaS applications purchased without the knowledge of the security team. While these applications may be legitimate, they operate within the blind spots of the corporate security team and expose the company to attackers.  Shadow apps may include instances of software that the company is already using. For example, a dev team may onboard their own instance of GitHub to keep their work separate from other developers. They might justify the purchase by noting that GitHub is an approved application, as it is already in use by other teams. However, since the new instance is used outside of the security team's view, it lacks governance. It may store sensitive corporate data and not have essential protections like MFA enabled, SSO enforced, or it could suffer from weak access controls. These misconfigurations can easily lead to risks like stolen source code and other issues. Types of Shadow Apps  Shadow apps can be categorized based on their interac

A widely used Chinese language input app for Windows and Android has been found vulnerable to serious security flaws that could allow a malicious interloper to decipher the text typed by users. The findings from the University of Toronto's Citizen Lab, which carried out an analysis of the encryption mechanism used in Tencent's Sogou Input Method , an app that has over 455 million monthly active users across Windows, Android, and iOS. The vulnerabilities are rooted in EncryptWall, the service's custom encryption system, allowing network eavesdroppers to extract the textual content and access sensitive data. "The Windows and Android versions of Sogou Input Method contain vulnerabilities in this encryption system, including a vulnerability to a CBC  padding oracle attack , which allow network eavesdroppers to recover the plaintext of encrypted network transmissions, revealing sensitive information including what users have typed," the researchers  said .

Thai activists involved in the country's pro-democracy protests have had their smartphones infected with NSO Group's infamous Pegasus government-sponsored spyware. At least 30 individuals, spanning activists, academics, lawyers, and NGO workers, are believed to have been targeted between October 2020 and November 2021, many of whom have been previously detained, arrested and imprisoned for their political activities or criticism of the government. "The timing of the infections is highly relevant to specific political events in Thailand, as well as specific actions by the Thai justice system," the Citizen Lab  said  in a Sunday report. "In many cases, for example, infections occurred slightly before protests and other political activities by the victims." The findings are the result of  threat notifications  sent by Apple last November to alert users it believes have been targeted by state-sponsored attackers. The attacks entailed the use of two zero-cl
