Microsoft said it won't be fixing or is pushing patches to a later date for three of the four security flaws uncovered in its Teams business communication platform earlier this March. The disclosure comes from Berlin-based cybersecurity firm Positive Security, which  found  that the implementation of the link preview feature was susceptible to a number of issues that could "allow accessing internal Microsoft services, spoofing the link preview, and, for Android users, leaking their IP address, and DoS'ing their Teams app/channels." Of the four vulnerabilities, Microsoft is said to have addressed only one that results in IP address leakage from Android devices, with the tech giant noting that a fix for the denial-of-service (DoS) flaw will be considered in a future version of the product. The issues were responsibly disclosed to the company on March 10, 2021. Chief among the flaws is a server-side request forgery ( SSRF ) vulnerability in the endpoint "/urlp...

China's internet regulator, the Ministry of Industry and Information Technology (MIIT), has temporarily suspended a partnership with Alibaba Cloud, the cloud computing subsidiary of e-commerce giant Alibaba Group, for six months on account of the fact that it failed to promptly inform the government about a critical security vulnerability affecting the broadly used Log4j logging library. The development was disclosed by  Reuters  and  South China Morning Post , citing a report from 21st Century Business Herald, a Chinese business-news daily newspaper. "Alibaba Cloud did not immediately report vulnerabilities in the popular, open-source logging framework Apache Log4j2 to China's telecommunications regulator," Reuters said. "In response, MIIT suspended a cooperative partnership with the cloud unit regarding cybersecurity threats and information-sharing platforms." Tracked as  CVE-2021-44228  (CVSS score: 10.0) and codenamed  Log4Shell  or LogJam, t...

A short-lived phishing campaign has been observed taking advantage of a novel exploit that bypassed a patch put in place by Microsoft to fix a remote code execution vulnerability affecting the MSHTML component with the goal of delivering Formbook malware. "The attachments represent an escalation of the attacker's abuse of the CVE-2021-40444 bug and demonstrate that even a patch can't always mitigate the actions of a motivated and sufficiently skilled attacker," SophosLabs researchers Andrew Brandt and Stephen Ormandy  said  in a new report published Tuesday. CVE-2021-40444  (CVSS score: 8.8) relates to a remote code execution flaw in MSHTML that could be exploited using specially crafted Microsoft Office documents. Although Microsoft addressed the security weakness as part of its September 2021  Patch Tuesday updates , it has been put to use in  multiple attacks  ever since details pertaining to the flaw became public. That same month, the technology g...

Microsoft is urging customers to patch two security vulnerabilities in Active Directory domain controllers that it  addressed in November  following the availability of a proof-of-concept (PoC) tool on December 12. The two vulnerabilities — tracked as  CVE-2021-42278  and  CVE-2021-42287  — have a severity rating of 7.5 out of a maximum of 10 and concern a privilege escalation flaw affecting the Active Directory Domain Services (AD DS) component. Credited with discovering and reporting both the bugs is Andrew Bartlett of Catalyst IT. Active Directory is a  directory service  that runs on Microsoft Windows Server and is used for identity and access management. Although the tech giant marked the shortcomings as " exploitation Less Likely " in its assessment, the public disclosure of the PoC has prompted renewed calls for applying the fixes to mitigate any potential exploitation by threat actors. While CVE-2021-42278 enables an attacker to tamp...

The transportation industry and government agencies related to the sector are the victims of an ongoing campaign since July 2020 by a sophisticated and well-equipped cyberespionage group in what appears to be yet another uptick in malicious activities that are "just the tip of the iceberg." "The group tried to access some internal documents (such as flight schedules and documents for financial plans) and personal information on the compromised hosts (such as search histories)," Trend Micro researchers Nick Dai, Ted Lee, and Vickie Su  said  in a report published last week. Earth Centaur, also known by the monikers  Pirate Panda  and Tropic Trooper, is a long-running threat group focused on information theft and espionage that has led targeted campaigns against government, healthcare, transportation, and high-tech industries in Taiwan, the Philippines, and Hong Kong dating all the way back to 2011. The hostile agents, believed to be a Chinese-speaking actor, are...
