REvil: Record of a gang of cyber extortionists

REvil has been one of the most prolific ransomware-as-a-service campaigns in recent memory. Thousands of technology companies, managed service providers, and organizations from a wide variety of industries worldwide have been among their victims. Bitdefender draws the preliminary balance sheet of an extortion enterprise. The cooperation between security authorities and IT experts led to great success in the second half of 2021. Joint efforts were necessary because the cyber criminals also cooperated successfully. The experts at Bitdefender Labs take stock of the – perhaps only temporary – failure of a successful wave of ransomware-as-a-service. International strikes against REvil backers Most recently, international investigators struck heavy blows against the criminal REvil backers: In…

IT security in medium-sized companies needs helping hands

IT security in medium-sized companies needs helping hands. More protection thanks to external experts from the Security Operation Center - SOC, as cyber attacks are becoming increasingly complex and require security specialists. A comment from Bitdefender. There is no such thing as XNUMX% security in IT. There will always be vulnerabilities such as unpatched software, leaked passwords or shadow IT that resourceful hackers can use to penetrate corporate networks. And as long as the attackers are human, they must be met by competent flesh-and-blood defenders. These experts are available through external MDR (Managed Detection and Response) services and Security Operation Center (SOC)…

Bitdefender: Five cybersecurity arenas

2021 will probably be remembered negatively in many ways in terms of cyber security. Unsurprisingly, the year ended with a thunderclap for the IT security industry: the Java Log4j vulnerability created the perfect framework for hackers. Log4j, ransomware, supply chain attacks are all coming in 2022. Jen Easterly, head of the US federal government's Cybersecurity and Infrastructure Security Agency (CISA), called the Log4j vulnerability the most serious flaw she has seen in her decade-long career . The effects of Log4j will be significant for IT, business and society in the coming months and possibly also in the…

Container security also offers attack surfaces

Risk awareness, classic cyber security principles and specific countermeasures increase the security of data and processes. IT managers use their own container security or those provided by cloud service providers in order to set up agile and flexible applications and operate processes. Ultimately, however, containers are also executable applications and can be dangerous. Container host servers and registries extend the attack surface. Classic principles of IT security and an increased sensitivity to threats help to close emerging gaps. Containers in the cloud or on-premise containers - whether kept privately or provided via a cloud provider - offer hackers ...

Log4j Log4shell

The experts at Bitdefender Labs report an initial assessment of Log4j and Log4Shell: Hackers are intensively looking for vulnerabilities. A Tor concealment of the accesses to real endpoints makes Germany the seemingly number one country of origin of the attacks. Bitdefender counted 36.000 hits on honeypots in seven days. The Log4Shell vulnerability has been actively exploited by Apache as CVE-9-2021 since it was disclosed on December 2021, 44228. The results are amazing. Most of the attack attempts seem to come from western industrialized countries such as Germany, the USA and the Netherlands, but apparently some of them hide their origin behind exit nodes of the Tor network. That puts ...
