The exploit at a democratic institution such as Stortinget is certainly ominous, perhaps more so than the woes in recent days of organisations such as the European Banking Authority. Stortinget president Tone Wilhelmsen Trøen said: "The attack we are facing shows that IT attacks can have serious consequences for democratic processes at worst."
Commentary: Enterprises try their best to secure their data, but running on-premises mail servers arguably doesn't do this. We can have a debate about how soon enterprises should embrace cloud.
Microsoft plugged as many as 89 security flaws as part of its monthly Patch Tuesday updates released today, including fixes for an actively exploited zero-day in Internet Explorer that could permit an attacker to run arbitrary code on target machines. Among those five security issues are a clutch of vulnerabilities known as ProxyLogon that allows adversaries to break into Microsoft Exchange Servers in target environments and subsequently allow the installation of unauthorized web-based backdoors to facilitate long-term access.
Criminals have been targeting organizations that run Exchange hoping to breach ones that haven't patched the latest bugs, says ESET. Four critical zero-day vulnerabilities in Microsoft Exchange have paved the way for attackers to take over accessible Exchange servers even without knowing the credentials. The four Exchange vulnerabilities in question were first uncovered by vulnerability researcher Orange Tsai, who reported them to Microsoft on Jan. 5, according to ESET. But security firm Volexity, which also alerted Microsoft, claims the exploitation of these flaws started on Jan. 3.
Update: Microsoft has released out-of-band non-security updates to address the Windows 10 printing crash issue. The Windows 10 KB5000802 and KB5000808 cumulative updates released yesterday are causing Blue Screen of Death crashes when printing to network printers.
Norway's parliament, the Storting, has suffered another cyberattack after threat actors stole data using the recently disclosed Microsoft Exchange vulnerabilities. Last week, Microsoft released emergency security updates for Microsoft Exchange to fix zero-day vulnerabilities, known as ProxyLogon, used in attacks.
More state-sponsored hacking groups have joined the ongoing attacks targeting tens of thousands of on-premises Exchange servers impacted by severe vulnerabilities tracked as ProxyLogon. Exchange servers attacked by multiple hacking groups.
With regards your question, I'm going to answer it in a bit more depth as there is a lot many realy do not realise both from a defenders and attackers point of view. The level of the attack signal rises and the level of the signals uncorrelated with the Zero Day attack go down do not remain covery long when you can "Go back in time" repeatedly with "Collect it All" databases.
Cyber sleuths have already blamed China for a hack that exposed tens of thousands of servers running its Exchange email program to potential hacks. The CEO of a prominent cybersecurity firm says it now seems clear China also unleashed an indiscriminate, automated second wave of hacking that opened the way for ransomware and other cyberattacks.
On the off chance you were looking for more security to-dos from Microsoft todaythe company released software updates to plug more than 82 security flaws in Windows and other supported software. This is probably a good place to quote Ghacks.net's Martin Brinkman: This is the last patch hurrah for the legacy Microsoft Edge web browser, which is being retired by Microsoft.
