Researchers in China claim to have reached a breakthrough in quantum computing, figuring out how they can break the RSA public-key encryption system using a quantum computer of around the power that will soon be publicly available.
Breaking 2048-bit RSA — in other words finding a method to consistently and quickly discover the secret prime numbers underpinning the algorithm — would be extremely significant. Although the RSA algorithm itself has largely been replaced in consumer-facing protocols, such as Transport Layer Security, it is still widely used in older enterprise and operational technology software and in many code-signing certificates.
macOS may alert you when you’re trying to open or run a file, with an alert informing you that malware was detected. But what about in scans?
Music-streaming service Deezer has owned up to a data breach, after hackers managed to steal the data of over 200 million of its users.
We recently discovered ransomware, which performs MSDTC service DLL Hijacking to silently execute its payload. We have named this ransomware CatB, based on the contact email that the ransomware group uses. The sample was first uploaded to VT on November 23, 2022 and tagged by the VT community as a possible variant of the Pandora Ransomware. The assumed connection to the Pandora Ransomware was due to some similarities between the CatB and Pandora ransom notes. However, the similarities pretty much end there. The CatB ransomware implements several anti-VM techniques to verify execution on a “real machine”, followed by a malicious DLL drop and DLL hijacking to evade detection.
Suite à un piratage, Adecco a lancé début novembre une enquête. La société donne de plus amples informations : « certaines de vos données personnelles présentes dans un de nos systèmes d’informations (noms, prénoms, adresses email...
The ASEC analysis team recently discovered that a Linux malware developed with Shc has been installing a CoinMiner. It is presumed that after successful authentication through a dictionary attack on inadequately managed Linux SSH servers, various malware were installed on the target system. Among those installed were the Shc downloader, XMRig CoinMiner installed through the former, and DDoS IRC Bot, developed with Perl.
A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong.
More than 200 local governments, schools and hospitals in the U.S. were affected by ransomware in 2022, according to research conducted by cybersecurity firm Emsisoft.
The annual “State of Ransomware in the US” report found that 105 local governments; 44 universities and colleges; 45 school districts; and 25 healthcare providers operating 290 hospitals dealt with ransomware attacks last year.
