Traffers threat: The invisible thieves

Traffers are cybercriminals organized in teams whose purpose is to steal a maximum of bankable information from infected computers, which they sell to other cybercriminals.

Cybercrime comes in many different flavors, most of it being financially-oriented. Phishers, scammers and malware operators are the most visible ones, yet there are some other profiles in the cybercrime economy who play an important role and are yet very discreet: Traffers.

#StopRansomware: Vice Society

Original release date: September 6, 2022

CISA, the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) have released a joint Cybersecurity Advisory (CSA), #StopRansomware: Vice Society, to disseminate tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) associated with Vice Society actors identified through FBI investigations as recently as September 2022. Vice Society uses ransomware attacks against the education sector to gain access to, and threaten exposure of, sensitive personal information regarding students and staff for financial gain.

CISA encourages organizations to review #StopRansomware: Vice Society for more information. Additionally, see StopRansomware.gov for guidance on ransomware protection, detection, and response.

Late evening, on September 6, 2022, the Wordfence Threat Intelligence team was alerted to the presence of a vulnerability being actively exploited in BuddyPress, a WordPress plugin we estimate has around 140,000 active installations. This vulnerability makes it possible for unauthenticated users to download arbitrary files from the affected site which can include sensitive information.

After reviewing historical data, we determined that attackers started targeting this vulnerability on August 26, 2022, and that we have blocked 4,948,926 attacks targeting this vulnerability since that time.

The vulnerability affects versions to, and has been fully patched as of September 6, 2022 in version 8.7.5. Due to the fact that this is an actively exploited vulnerability, we strongly encourage you to ensure your site has been updated to the latest patched version 8.7.5 which iThemes has made available to all site owners running a vulnerable version regardless of licensing status.
