NVIDIA confirmed that employee credentials and proprietary data such as schematics, drivers, and firmware were stolen and leaked. Rental car company Localiza was a victim of a defacement attack. Telecommunications companies Claro, Embratel, and NET were breached, and sensitive data such as customer information, infrastructure data, source code, and wiretap orders were stolen. Here are some of the claimed victims of the LAPSUS$ cyber threat group.ĬOVID database of the Brazilian Ministry of Health was compromised, and confidential data was stolen. For initial access, the LAPSUS$ group tries to recruit insiders from their potential targets.įigure 1: LAPSUS$ group’s recruitment message ![]() ![]() The main targets are large technology companies that operate in the telecommunications, hardware, software, and game industries. In a short amount of time, the LAPSUS$ threat group has claimed to exfiltrate data from various organizations and demanded money for not disclosing sensitive information to the public. ![]() However, their operations have grown larger and become worldwide. The LAPSUS group was first seen in December 2021, and their attacks were aimed at organizations in the United Kingdom and South American countries. LAPSUS$ is a cyber extortion group that targets large government and commercial organizations. Picus Labs added attack simulations for LAPSUS$ operations to the Picus Threat Library, and you can test your security controls against LAPSUS$ attacks. In this blog, we explained the LAPSUS$ threat group in detail. However, the LAPSUS$ extortion group has eliminated the file encryption and machine lockout techniques used by traditional ransomware groups. Like ransomware gangs, LAPSUS$ exfiltrates confidential data from breached organizations and then threatens to leak or disclose data if the demanded ransom was not paid. You can watch the video above showing his hack.A novel cyber threat group called LAPSUS$ ( DEV-0537 ) launched cyberattacks against various organizations such as the Ministry of Health of Brazil, NVIDIA, Samsung, Octa, and Microsoft. Vilaca had tweaked his Gopher ransomware to bypass RansomWhere in a matter of minutes.Īs mentioned in the limitations, Vilaca added just ten lines of code in its ransomware proof-of-concept to take the victim's files outside of the home directory and lock them up. Since hackers are always a step ahead of researchers, the RansomWhere tool has already been bypassed. So sophisticated ransomware could shift all your files outside home directory and lock them up. Files outside of your home directory are not protected by RansomWhere.RansomWhere detects ransomware infections after they have already encrypted some of your important files.RansomWhere would not be able to help if any Ransomware malware abuses Apple-signed file or app.Some known Limitations of RansomWhere tool?: Though Wardle admitted that his tool does not guarantee 100 percent result and that it could be circumvented by malicious hackers who can discover a way to bypass RansomWhere and avoid detection, it is always better to be somewhat safer than completely vulnerable. Wardle successfully tested RansomWhere against KeRanger as well as Gopher ransomware proof-of-concept, which was developed by a pro-Apple Mac hacker, Pedro Vilaca, last year.Īlso Read: How Just Opening an MS Word Doc Can Hijack Every File On Your System. If the tool detects any untrusted process, it suspends the suspicious process and alerts the user by showing a pop-up asking user to continue or terminate the process in question. This ransomware detection tool, by default, scans Mac apps and binaries that are signed with an Apple Developer ID and not by official Apple certificates. "The ransomware will likely encrypt a few files (ideally only two or three), before being detected and blocked," Wardle wrote in a blog post. Patrick Wardle, a former NSA staffer who now leads research at bug hunting outfit Synack, has developed the RansomWhere tool, which aims at detecting and blocking generic ransomware on Mac OS X by regularly monitoring the user's local filesystem for the creation of encrypted files by any process. RansomWhere? – a smart application that can identify ransomware-like behavior by detecting untrusted processes rapidly encrypting files, stop that suspicious process, and then alert the user. Here's the latest ransomware detection tool for Mac OS X users: Some Antivirus companies have already upgraded their security solutions that detect suspicious behaviors like the sequential accessing of a large number of files, using encryption algorithms and key exchange mechanisms.
