Over 80 percent of exposed Exchange servers are still vulnerable to a severe vulnerability - nearly two months after the flaw was patched, and after researchers warned that multiple threat groups were exploiting it. Researchers recently used Project Sonar, a scanning tool, to analyze internet-facing Exchange servers and sniff out which were vulnerable to the flaw.

Online exchange rate data provider Open Exchange Rates has exposed an undisclosed amount of user data via an Amazon database, according to a notification letter published on Twitter this week. Open Exchange Rates provides foreign exchange data for over 200 currencies worldwide, including digital ones.

Organizations have fallen behind with the patching of a Microsoft Exchange Server vulnerability addressed with Microsoft's February 2020 Patch Day updates and already targeted in attacks. The issue, which exists because keys created at installation are not unique, is tracked as CVE-2020-0688 and impacts Microsoft Exchange 2010, 2013, 2016, and 2019.

Currency data provider Open Exchange Rates has started informing customers that their information was likely stolen by hackers. Open Exchange Rates provides a currency data API that is used by over 80,000 web developers.

Multiple threat actors are already targeting Microsoft Exchange servers in an attempt to exploit a vulnerability fixed by Microsoft with its February 2020 Patch Tuesday updates. Tracked as CVE-2020-0688 and found in Microsoft Exchange 2010, 2013, 2016, and 2019, the issue exists because the server doesn't create unique cryptographic keys at the time of installation, which allows an authenticated attacker to trick the server into deserializing malicious ViewState data.

An IT startup has developed a novel blockchain-based approach for secure linking of databases, called ChainifyDB. "Our software resembles keyhole surgery. With a barely noticeable procedure we enhance existing database infrastructures with blockchain-based security features. Our software is seamlessly compatible with the most common database management systems, which drastically reduces the barrier to entry for secure digital transactions," explains Jens Dittrich, Professor of Computer Science at Saarland University at Saarbrücken, Germany. "If a doctor changes something in his table, it affects all other tables in the network. Subsequent changes to older table states are only possible if all doctors in the network agree," explains Jens Dittrich.

Multiple threat groups are actively exploiting a vulnerability in Microsoft Exchange servers, researchers warn. After Microsoft patched the flaw in February researchers with the Zero Day Initiative, which first reported the vulnerability, published further details of the flaw and how it could be exploited.

Healthcare industry at greatest risk of data breachThe healthcare industry has significantly more exposed attack surfaces than any other industry surveyed, according to Censys's research findings of cloud risks and cloud maturity by industry, revealed at RSA Conference 2020. Attackers probing for vulnerable Microsoft Exchange Servers, is yours one of them?CVE-2020-0688, a remote code execution bug in Microsoft Exchange Server that has been squashed by Microsoft in early February, is ripe for exploitation and could become a vector for ransomware groups in coming months, warns cybersecurity researcher Kevin Beaumont.

Hackers have started scanning the Internet for Microsoft Exchange Server instances that are affected by a remote code execution vulnerability patched earlier this month. The issue resides in the Exchange Control Panel component and consists of Exchange Server installations having the same validationKey and decryptionKey values in web.
