Bazar

Bazar is a form of malware, or malicious software, that has been used by cybercriminals to exploit and damage computer systems. This harmful program infiltrates systems through suspicious downloads, emails, or websites, often without the user's knowledge. Once inside, it can steal personal information, disrupt operations, or even hold data hostage for ransom. Bazar has different components known as BazaLoader, BazarLoader, and BazarBackdoor. The Bazar DLL, masquerading as a jpg, notably uses HTTPS C2 throughout the full intrusion process. Typical child processes associated with Bazar include cmd.exe, svchost.exe, explorer.exe, nltest.exe, and net.exe. The use of Bazar in cyberattacks represents a new technique for criminals to infect and monetize networks. This method has increasingly led to the deployment of ransomware, including Ryuk. An example of such an attack is illustrated in the Conti attack diagram, which shows the progression from the Bazar backdoor to ransomware. This strategy is not innovative but rather a tried-and-true technique that defenders are already taking on. Even partial automation can enable the scaling of cybercrime, a tactic already seen in Bazar campaigns. Despite these challenges, efforts are being made to combat the threat posed by Bazar. For instance, blockchain technology is being employed to create tamper-proof systems, as demonstrated by the proposed signalling system at Bahanaga Bazar railway station following a devastating train accident. However, there is still much work to be done, as evidenced by the ongoing Bazar ransomware story. As cyber threats continue to evolve, so too must the strategies and technologies used to defend against them.
