Log4j has been the talk of the town for several weeks now. We have also already commented on this in a detailed post blog about Log4j and Log4Shell.

The second major release of this year is notably not only for extensive improvements but also for the unification of management and configuration functions under one interface: the web-based "DriveLock Operations Center" (DOC). This web-based DOC is the central interface for overviews, dashboards and report generation.

The background story is that despite the existence of the Kaseya vulnerability, a decent endpoint security solution could have provided better outcome. Because in the worst case, the malware could have been installed, but the security solution would have prevented its execution - and thus also the encryption of the endpoints.
The media recently reported that a hacker attack via IT service provider Kaseya affects thousands of companies.
zdnet.com reported “attackers managed to compromise the vendor's software to push a malicious update to thousands of customers. (…) an estimated 1,000 companies have had servers and workstations encrypted. The vendor added that it is reasonable to suggest "thousands of small businesses" may have been impacted. (…) The cyberattack has been attributed to the REvil/Sodinikibi ransomware group who have ties to Russia, which has claimed responsibility on its Dark Web leak site, "Happy Blog."”.
This shows that the attack hit companies of all sizes, as well as across multiple verticals. So, irrespective of the budget or vertical, everyone is vulnerable.
At the time of an attack in a zero-day exploit - i.e. a targeted exploitation of a known or unknown vulnerability in a piece of software - we know nothing about the attack tactics or the attack vectors. But we know that we have to protect ourselves against the unknown. Therefore, I am not so much concerned with the vulnerability in the Kaseya infrastructure per se, but rather with how we can successfully prevent the exploitation of all vulnerabilities and thus allow companies to be secure.
Through a simplified summary of the somewhat complex process I would like to show where DriveLock solutions could have helped to avoid the attacks.
For the following sections I refer to the Sophos News website.
REvil was able to deploy and run its dropper locally to all customers’ endpoints without testing through the Kaseya agent. Certain directories on the endpoint are deliberately and intentionally ignored by the Kaseya agent through exclusions. This opened the way for a malicious payload agent.crt file to be written to the VSA agent's working directory for updates. After deploying the payload, the Kaseya agent then executed the following Windows shell commands concatenated into a single string:

“There are only two types of companies: those that have been hacked, and those that will be."
Former FBI Director Robert Mueller
No one can escape the threat of a cyber attack. One vulnerability is all an attacker needs to gain unprecedented access to all of your organisation’s confidential files and information. Not only is your company’s data at risk, but also your client’s. So it is of paramount importance that your organisation strengthens its cyber security software and practices. But how confident are you in your company’s ability to counteract cyber attacks?

Stay on the "bright side of life".
Recently, the attack by the "Darkside” hacker group on the pipeline operator Colonial in the USA has once again brought the topic of IT security into the spotlight. The attack was covered in mainstream news and caused panic buying as well as petrol shortages on the East Coast of the U.S., and even led to a state of emergency being declared in some U.S. states. This shows that attacks, specifically those targeting companies in the critical infrastructure field, can have enormous impacts on society.
