Ransomware attackers seem to have no bounds to their greed. In the latest attack on MediaMarkt, the Hive ransomware group demanded a whopping, unrealistic $240 million ransom to offer a decryptor for the encrypted files of the electronics retail giant. Meanwhile, two different ransomware groups and an APT group have associated with a common initial access broker, dubbed Zebra2104, to conduct their malware campaigns. In other news, an Iranian hacking group, Lyceum, was spotted targeting ISPs and telecoms to deploy two different types of malware.
While researchers discovered multiple vulnerabilities in BusyBox that could allow DoS attacks, remote code execution, and leak information, a patched vulnerability in Sitecore XP was exploited again. Online scammers are on a roll; a group of threat actors was found forcing victims to be money mules by entrapping them through fraudulent websites that offered low-priced consumer electronic products. Moreover, scammers are tricking victims into leveraging cryptocurrency ATMs and QR codes to make payments. The FBI warned the public against such scammers.
