Lilocked ransomwareĪlso known as Lilu, this strain of Linux ransomware debuted in mid-July 2019. Otherwise, the amount will be increasing by 10% daily. The ransom note instructs the victim to contact the attackers and pay for data recovery in Bitcoin within 60 hours. Tycoon scrambles each file on a server using a different AES key, which is further encoded with the RSA-1024 key owned by the perpetrators.
The infection comes with a configuration file storing the text of the ransom note, the RSA public key, the malefactor’s email address, and the list of network components to skip during the dodgy encryption. It supports Linux and Windows frameworks alike, so the subsequent attack chain depends on the OS used in the victim network. The final-stage harmful Java object is executed by a peculiar shell script behind the scenes.

Once the surreptitious infiltration into an enterprise network has been completed, the predatory code is compiled into a Java image (JIMAGE) entity that allows the attackers to create a custom JRE build exhibiting malicious characteristics. Its operators tend to piggyback on unsecured remote desktop protocol (RDP) ports as the original entry point.

The Tycoon payload arrives with a booby-trapped ZIP archive that contains a malicious Java Runtime Environment (JRE) component.

The intended set of victims ranges from software publishers to educational institutions, with the raids being highly targeted. For the record, it is a two-pronged strain that can infect Windows machines as well. Having splashed onto the scene in early December 2019, Tycoon is the latest example of Linux ransomware. The following infamous outbreaks of these infections will shed light on the heterogeneous essence of this cyber threat landscape while highlighting effective defenses organizations should implement to stay on the safe side. Linux ransomware runs the gamut of different distribution techniques and extortion methods. Their owners are mostly businesses or governmental institutions with sizeable budgets that can afford to pay for reverting to regular operation. In plain words, these devices are juicy targets to take hostage. Linux is widely deployed on servers that administer enterprise networks, massive databases, and web services. This might seem like a marginal tactic at first sight, but once you explore the wiki facet of the matter, the attackers’ logic starts making a whole lot of sense. The Linux ecosystem is a steadily expanding battlefield in this regard. Whereas the vast majority of ransom Trojans zero in on Windows PCs, some strains focus on devices running other operating systems instead. A combination of military-grade encryption and effective extortion mechanisms makes every such attack potentially disastrous as the victim runs the risk of losing essential data down the line. The ransomware plague has been the talk of the cybersecurity town since the emergence of CryptoLocker back in 2013.
