APT groups use ransomware TTPs as cover for intelligence gathering and sabotage (lien direct) |
State-sponsored threat groups increasingly use ransomware-like attacks as cover to hide more insidious activities. Russian advanced persistent threat (APT) group Sandworm used ransomware programs to destroy data multiple times over the past six months while North Korea's Lazarus group used infrastructure previously associated with a ransomware group for intelligence gathering campaigns.At the same time, some Chinese APTs that were traditionally targeting entities in Asia shifted their focus to European companies, while Iran-based groups that traditionally targeted Israeli companies started going after their foreign subsidiaries. At least one North Korean group that was focused on South Korea and Russia has started using English in its operations. All these operational changes suggest organizations and companies from Western countries are at increased risk from APT activity.To read this article in full, please click here |

WannaCry explained: A perfect ransomware storm (lien direct) |
What is WannaCry?
WannaCry is a ransomware worm that spread rapidly through across a number of computer networks in May of 2017. After infecting a Windows computer, it encrypts files on the PC's hard drive, making them impossible for users to access, then demands a ransom payment in bitcoin in order to decrypt them.A number of factors made the initial spread of WannaCry particularly noteworthy: it struck a number of important and high-profile systems, including many in Britain's National Health Service; it exploited a Windows vulnerability that was suspected to have been first discovered by the United States National Security Agency; and it was tentatively linked by Symantec and other security researchers to the Lazarus Group, a cybercrime organization that may be connected to the North Korean government.To read this article in full, please click here |
