What is KryptoCibule?

It uses victim's computer hardware (resources) to mine cryptocurrency, can replace wallet addresses in the system clipboard and exfiltrate cryptocurrency-related files.

KryptoCibule malware

Research shows that the latest version of the KryptoCibule malware uses XMRig to mine Monero cryptocurrency using victim's CPU (Central Processing Unit), and kawpowminer to mine Ethereum cryptocurrency using victim's GPU (Graphics Processing Unit). Mining process often causes high CPU and/or GPU usage, therefore, infected computer may run slowly or not respond at all. Also, it may cause system crashes, loss of unsaved data, hardware overheat, or other issues. It is worthwhile to mention that computers used to mine cryptocurrency use more electricity, therefore, users receive higher electricity bills. Furthermore, KryptoCibule monitors changes in the system clipboard, when it detects an address of a cryptocurrency wallet copied by a victim, then this malware replaces it with the address of a wallet (or wallets) controlled by cyber criminals behind it. Therefore, victims may unknowingly transfer cryptocurrency to cyber criminals more than a few times without even knowing that. Also, this malware exfiltrates certain cryptocurrency-related files, it looks for filenames that contain terms related to cryptocurrencies, wallets, miners, private keys, and sends them to cyber criminals. To sum up, KryptoCibule is a cryptocurrency-related malware that can be used by cyber criminals as a tool to use infected computers (their hardware) to mine cryptocurrency, steal hijack cryptocurrency transactions and steal files related to wallets, miners, etc.

How did KryptoCibule infiltrate my computer?

Research shows that KryptoCibule is distributed through ZIP files that contain installers for cracked or pirated software, games. These ZIP files are distributed through malicious torrents. Additionally, users who have downloaded files used to distribute KryptoCibule are used to seed both the torrents used by the malicious software and the malicious torrents that help spread it. It means that malicious files are available for other users to download, which helps spread the KryptoCibule faster. It is worthwhile that cyber criminals can use other Peer-to-Per networks (like eMule) to spread malware too. Also, they often use malspam campaigns (emails), other untrustworthy file and software download sources like unofficial pages, free file hosting pages, freeware download sites, unofficial software activation tools, third party updaters as tools to trick users into installing malware on their computers.

How to avoid installation of malware?

It is important update and/or activate software with tools that are designed by official software developers and not some third party activation, updating tools. Such tools often are the reason behind unintentional installation of malware. Besides, it is not legal to use 'cracking' to activate any licensed software. Programs and files should not be downloaded (or installed) through third party downloaders, installers, Peer-to-Peer networks from unofficial pages, and other channels, sources of this kind. The safest way to do it is to use official websites and direct links for that. Attachments and website links in irrelevant emails that are sent from unknown, suspicious addresses should not be opened. It is common that such emails are sent by cyber criminals, besides, they often disguise them as important, official. One more way to keep operating systems safe is to regularly scan them for threats with a reputable antivirus or anti-spyware software. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.
