To start, our stance is that the industry should no longer stand for the status quo related to the lack of cybersecurity tool effectiveness, manual discovery, and remediation, and the general settling for lack of threat surface coverage and network visibility of the entire enterprise.
For companies gutsy enough to change, there is a better approach to finding and stopping cyber threats and attacks—ARIA CloudADR. We’ll wrap up addressing how the solution solves for the poor performance and share details on a free three-month offer of ARIA ADR to help with the recovery of the breach.
Zero-day strikes again
At least 30,000 businesses and government agencies across the U.S.—including a significant number of small businesses, towns, cities, and local governments—have been targeted by an aggressive zero-day hacking campaign exploiting four recently discovered vulnerabilities in the Microsoft Exchange Server.
These vulnerabilities are present in on-premises versions of Microsoft Exchange Server email software, and some experts estimate that hundreds of thousands of Exchange Servers may have been affected. This situation also allows the potential installation of additional malware to facilitate long-term access to infected environments.
Microsoft is attributing these exploits to a Chinese state-sponsored cyber-espionage organization known as HAFNIUM. The unit was conducting targeted attacks on Microsoft email systems used by a range of industry sectors, including but not limited to: infectious disease researchers, law firms, higher education institutions, defense contractors, policy think tanks, and NGOs.
Microsoft’s response may not be good enough
Once alerted to the hack—first noticed on Jan 6 by an outside organization, Volexity— Microsoft issued emergency security updates to plug four security holes on March 2. The vulnerability extended to Exchange Server versions 2013 through 2019, where HAFNIUM hackers actively used them to siphon email communications from Internet-facing systems running Exchange.
Microsoft’s response was to apply updates to patch the vulnerability. “The best protection is to apply updates as soon as possible across all impacted systems. We continue to help customers by providing additional investigation and mitigation guidance.”
However, patching the flaws only blocks the four ways that the hackers could get into the network. If the hackers are already in your network – it does nothing. Remember, the web shell that HAFNIUM was using had been in place for months before it was discovered back in January; no patch was ready until March, which means there is a high chance that your Exchange Server has already been hacked.
Companies that may have been exposed must focus on the fact that these intruders are sophisticated, and they likely want access to more than just your emails. They can jump from the infected Exchange server to other servers or devices in your environment across your network.
The Microsoft data breach is so serious that the U.S. Cybersecurity Infrastructure Security Agency (CISA) issued an emergency directive ordering all federal civilian departments and agencies running vulnerable Microsoft Exchange servers to update the software or disconnect the products from their networks.
Even the White House said that the “ … vulnerabilities found in Microsoft’s widely used Exchange servers were “significant” and “could have far-reaching impacts.” At the time, it seemed unlikely that there could be a hack as bad, or worse, than Sunburst, and yet the events of the past few days may well end up far eclipsing the damage done by the SolarWinds intruders.
What is Microsoft and other industry experts say should be done
Finding and removing the intruders is not going to be easy. The longer it takes to remove the backdoor (or doors, in this case), the more likely it is that the intruders will install additional ways in and broadening the cyber attack to include other portions of the victim’s network infrastructure.
Microsoft recommends the following actions:
In reality, what should be done
The five points above are familiar and represent sound advice that may have worked five years ago, but not anymore. This “old school” thinking from Microsoft shows how ill-prepared the industry is to find and stop sophisticated attacks that have become the norm. Sophisticated cyber attackers don’t use technology from a decade ago – they use zero-day approaches that must be detected by the abnormal device or application behaviors. Everything else above, other than applying the patch correctly – is the wrong thing to do to stop the attackers!
Our ARIA CloudADR was purpose-built to alleviate these challenges associated with today’s threat detection and response processes.
ARIA CloudADR automatically stops the attackers by detecting any abnormal communications from within the network’s network and movements. It can stop those communications and lateral movements, as well as stopping data exfiltration. With the ARIA CloudADR solution, attacks can’t hide, and the attackers’ obfuscation techniques don’t work. Nothing gets lost in the noise.
With ARIA CloudADR, an organization’s entire environment from the cloud to its on-premises infrastructure and remote devices is fully protected.
In a single, cloud-based platform, organizations gain not only a solution that works right out-of-the-box and:
It is all in a solution that can be operated part-time IT staff with little to no security training–operated from anywhere!
The good news is we can work with you to deploy our solution in a few hours. Right now, we are extending our 3-month free trial we offered to help those ORION users find the intruders- to Microsoft exchange users. Our goal is to help you find out if you have been hacked and stop the intruders. If you like what we do for you – subscribe to keep our solution working for you to stop the next attack.
