At least four state-sponsored hacking groups are exploiting the Microsoft Exchange Server vulnerability as part of ongoing attacks to achieve remote code execution without authentication on unpatched on-premises Exchange servers. Microsoft addressed the four zero-days Tuesday via emergency out-of-band security updates. Microsoft identified one of the threat actors as APT group Hafnium who operates out of China. The Cybersecurity and Infrastructure Security Agency (CISA) has issued an emergency directive and mandates patching for the issues.
According to Malaysia Airlines, the breach occurred at a third-party IT service provider who notified the airline that member data was exposed between March 2010 and June 2019.

The malware families include: two backdoors called GoldMax and the other called Sunshuttle, discovered by Microsoft and FireEye; a dual-purpose malware called Sibot discovered by Microsoft; and a malware called GoldFinder also found by Microsoft. Microsoft said that it found these latest custom attacker tools lurking in some networks of customer compromised by the SolarWinds attackers.
Over the past few weeks, three of the longest-running Russian-language online forums serving thousands of experienced cybercriminals have been hacked. Maza is one of the oldest and elite crime communities, with one of the highest entry barriers for hackers. This week attackers dumped thousands of usernames, email addresses and obfuscated passwords on the dark web apparently belonging to Maza. The leaked data consists of approximately 2,982 user records. The compromise of these hacking forums has many community members concerned that their real-life identities could be exposed and believing it is the work of a government agency.
