Cisco’s Talos threat intelligence researchers have identified an ongoing cybersecurity problem that looms within Facebook: dozens of groups created to trade and purchase spamming and phishing services.
The groups have been noted as partaking in “shady (at best) and illegal (at worst) activities,” using easily identifiable and locatable names such as “Spammer & Hacker Professional” or “Facebook hack (Phishing)” and yet remained up and active without intervention from Facebook itself.
Researchers at Cisco have found approximately 74 groups that partook in cybercriminal activities such as selling stolen login and account credentials and banking information. Others would sell tools for email spamming. The groups had amassed around 385,000 members in total and were easy to search for through simple keyword phrases like “spam” and “carding” when one looked into Facebook group search.
Cisco’s Talos team had notified Facebook about the hacker groups through abuse reporting, to which Facebook had responded by removing a few of the groups while keeping others up and only removing some posts deemed as a violation of policy. After the Talos researchers spoke directly with Facebook’s security team, the groups were taken down, but the issue of cybercrime on the social media site still remains a prevalent problem as new groups always seem to emerge.
Such activity isn’t new to the Facebook community. Groups like these have been operating for years on the social media platform. Brian Krebs from KrebsonSecurity had found 120 cybercrime groups back in 2018, for example, notifying Facebook in order to have the groups removed.
A spokesperson told The Verge that “[Facebook] know[s] [it] needs to be more vigilant and [they’re] investing heavily to fight this type of activity.”
