- Apple has released security updates to a remote code execution zero-day vulnerability that was discovered earlier this month in WebKit, the browser engine used by Safari and other apps, tracked as CVE-2022-3289.
- Microsoft has discovered a high severity vulnerability in the TikTok app for Android (CVE-2022-28799) that could have allowed attackers to take over accounts. The vulnerability has been patched.
Threat Intelligence Reports
- Security Researchers have conducted an analysis of Raspberry Robin infection to reveal what may be the objectives of the threat actors behind the malware. Following the investigation, the researchers have found similarities between the Raspberry Robin infection and the Dridex malware and as such, concluded that there may be a link between Raspberry Robin infections and the Russian cybercriminal group – ‘Evil Corp’.
- Security Researchers have discovered a new Remote Access Trojan (RAT) dubbed CodeRAT which specifically targets Farsi-speaking software developers using a Microsoft Word document that contains a Microsoft Dynamic Data Exchange (DDE) exploit. The researchers have been able to identify the malware creator, who then published the RAT’s source code in his public GitHub account.
- The National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have released a page designed to provide guidance for developers to ensure stronger security practices in the face of supply chain attacks.
- Security researchers have highlighted a risky feature in one third of Python packages – when a Python package is downloaded, automatic code is being executed, which exposes developers to a higher risk of a supply chain attack.
- Microsoft has announced that it plans to disable basic authentication in Exchange Online tenants worldwide in order to improve security and make it more difficult for threat actors to steal sensitive information using man-in-the-middle attacks. Basic authentication will be replaced permanently by modern authentication methods on the first week of January 2023.
