Companies are silent about notifiable attacks

Every third person responsible for cyber security in a company has already been instructed to conceal a reportable attack. The study shows: 14,7 percent then concealed the incident. The global Bitdefender 2023 Cybersecurity Assessment Report proves that GDPR, GDPR and other regulations are too often broken in favor of a good image. Bitdefender has published its 2023 Cybersecurity Assessment Report. The report is based on an independent and anonymous survey of more than 400 IT and cybersecurity professionals from IT manager to CISO in the US, UK, Germany, France, Italy and Spain in companies...

Spray and pray attacks against ManageEngine IT tools

Since January 2023, cybercriminals have been targeting implementations of Zoho Corporation's ManageEngine software solutions worldwide with an opportunistic attack. Cyber ​​criminals use automated scans to tap into a large field of potential victims of ransomware or industrial espionage. Bitdefender Labs analyzed the first attacks in their telemetry. The new campaign is another example of the more common opportunistic, initially automated vulnerability scans by cybercriminals followed by hybrid targeted attacks. The aim of the attackers is to execute code remotely (Remote Code Execution – RCE) in order to play out additional payloads or to start industrial espionage....

How ChatGPT will support cybercriminals

The OpenAI ChatGPT chatbot proves how artificial intelligence and machine learning can directly determine life and everyday life. Advanced IT users will use such tools for their purposes. And with that, unfortunately, cybercriminals too. OpenAI's ChatGPT AI model is based on unsupervised learning. With this ML approach, an AI model is fed with a large data set of unlabeled data. The vast corpus of material of books, articles and websites is based on pre-2021 sources and has no connections to the current internet. But that is already enough to learn the structures of natural language and to deceptively…

SSRF attacks on Microsoft Exchange Server

In an analysis, Bitdefender warns of a series of ProxyNotShell/OWASSRF attacks targeting on-premise Microsoft Exchange installations. The attack often even ends in taking over the server. A technical guide from Bitdefender offers help. The attacks observed since the end of November 2022, especially in the USA, served different purposes. Server-Side Request Forgery (SSRF) attacks enable opportunistic attacks via a vulnerable server on another server and can lead to the complete takeover of a Microsoft Exchange server, for example. Vulnerabilities in such high-level architectures are rarely found. If available, they can only be used in productive systems...

VMware-ESXi: Attacks threaten tens of thousands of servers

The attacks on the VMware ESXi never end. They continue to threaten tens of thousands of servers and require updating to the latest VMware ESXi version, according to Bitdefender experts. Even rescue scripts no longer work because the ransomware has adapted. The attacks on the VMware ESXi hypervisors, which exploit the recently discovered CVE-2021-21974 vulnerability with little effort to play a wide variety of payloads as remote code, have enormous potential for spreading. They are therefore developing into mass attacks for opportunistic cybercriminals and are a current example of hybrid attacks: VMware-ESXi : Example of hybrid attack In…

2023: Enterprises must optimize their IT defenses

Cyber ​​criminals never stand still. They constantly improve their methods and intensify their attacks on available targets. In 2023, companies will once again be faced with the task of further optimizing their IT defenses. When it comes to cyber insurance, a good defense is also expected or there is no policy. 2022 was not a quiet year for IT security either. Hackers have crossed new borders: Organized criminals attacked governments, like Conti in the Costa Rica case. The Lapsus$ group attacked well-known players in the digital economy such as Microsoft, Nvidia, Uber, Globant and others. Hacker collectives developed sophisticated, powerful tools for…

Cost-benefit analysis of IT security

| Bitdefender, Stories

IT security has a problem: it doesn't make any profits. For many it is still too expensive. However, the benefits of cyber defense can be demonstrated by a cost-benefit analysis with an IT security platform. There are five factors that can do this. Without a doubt, cyber defense causes additional costs beyond the pure license price. Because security software is not only to be obtained and installed quickly. Overtime that takes up time resources can never be ruled out. Its benefits often only become apparent when IT teams are willing and able to work with it. Security must be resource intensive….
