On April 5, 2023, the FBI and Dutch National Police  announced the takedown of Genesis Market , one of the largest dark web marketplaces. The operation, dubbed "Operation Cookie Monster," resulted in the arrest of 119 people and the seizure of over $1M in cryptocurrency. You can read the FBI's warrant  here  for details specific to this case. In light of these events, I'd like to discuss how OSINT can assist with dark web investigations. The Dark Web's anonymity attracts a variety of users, from whistleblowers and political activists to cybercriminals and terrorists. There are several techniques that can be used to try and identify the individuals behind these sites and personas. Technical Vulnerabilities While not considered OSINT, there have been instances when technical vulnerabilities have existed in the technology used to host dark websites. These vulnerabilities may exist in the software itself or be due to misconfigurations, but they can sometimes revea...

Cybersecurity researchers have uncovered a privilege escalation vulnerability in Google Cloud that could enable malicious actors tamper with application images and infect users, leading to supply chain attacks. The issue, dubbed  Bad.Build , is rooted in the  Google Cloud Build service , according to cloud security firm Orca, which discovered and reported the issue. "By abusing the flaw and enabling an impersonation of the default Cloud Build service, attackers can manipulate images in the Google Artifact Registry and inject malicious code," the company  said  in a statement shared with The Hacker News. "Any applications built from the manipulated images are then affected and, if the malformed applications are meant to be deployed on customer's environments, the risk crosses from the supplying organization's environment to their customers' environments, constituting a major supply chain risk." Following responsible disclosure, Google has  issued  a ...

The U.S. government on Tuesday added two foreign commercial spyware vendors, Cytrox and Intellexa, to an economic blocklist for weaponizing cyber exploits to gain unauthorized access to devices and "threatening the privacy and security of individuals and organizations worldwide." This includes the companies' corporate holdings in Hungary (Cytrox Holdings Crt), North Macedonia (Cytrox AD), Greece (Intellexa S.A.), and Ireland (Intellexa Limited). By adding to the economic denylist, it prohibits U.S. companies from transacting with these businesses. "Recognizing the increasingly key role that surveillance technology plays in enabling campaigns of repression and other human rights abuses, the Commerce Department's action today targets these entities' ability to access commodities, software, and technology that could contribute to the development of surveillance tools that pose a risk of misuse in violations or abuses of human rights," the Bureau of Indus...

An unidentified threat actor compromised an application used by multiple entities in Pakistan to deliver  ShadowPad , a successor to the PlugX backdoor that's commonly associated with  Chinese hacking crews . Targets included a Pakistan government entity, a public sector bank, and a telecommunications provider, according to Trend Micro. The infections took place between mid-February 2022 and September 2022. The cybersecurity company said the incident could be the result of a supply-chain attack, in which a legitimate piece of software used by targets of interest is trojanized to deploy malware capable of gathering sensitive information from compromised systems. The attack chain takes the form of a malicious installer for  E-Office , an application developed by the National Information Technology Board (NITB) of Pakistan to help government departments go paperless. It's currently not clear how the backdoored E-Office installer was delivered to the targets. That said, ...

Data associated with a subset of registered customers of VirusTotal, including their names and email addresses, were exposed after an employee inadvertently uploaded the information to the malware scanning platform. The security incident, which comprises a database of 5,600 names in a 313KB file, was first disclosed by  Der Spiegel  and  Der Standard  yesterday. Launched in 2004, VirusTotal is a popular service that analyzes suspicious files and URLs to detect types of malware and malicious content using antivirus engines and website scanners. It was acquired by Google in 2012 and became a subsidiary of Google Cloud's Chronicle unit in 2018. When reached for comment, Google confirmed the leak and said it took immediate steps to remove the data. "We are aware of the unintentional distribution of a small segment of customer group administrator emails and organization names by one of our employees on the VirusTotal platform," a Google Cloud spokesperson told The Ha...
