Deleted Facebook Cybercrime Groups Had 300,000 Members

Hours after being alerted by KrebsOnSecurity, Facebook last week deleted almost 120 private discussion groups totaling more than 300,000 members who flagrantly promoted a host of illicit activities on the social media network’s platform. The scam groups facilitated a broad spectrum of shady activities, including spamming, wire fraud, account takeovers, phony tax refunds, 419 scams, denial-of-service attack-for-hire services and botnet creation tools. The average age of these groups on Facebook’s platform was two years.

Don’t Give Away Historic Details About Yourself

Social media sites are littered with seemingly innocuous little quizzes, games and surveys urging people to reminisce about specific topics, such as “What was your first job,” or “What was your first car?” The problem with participating in these informal surveys is that in doing so you may be inadvertently giving away the answers to “secret questions” that can be used to unlock access to a host of your online identities and accounts.

I’m willing to bet that a good percentage of regular readers here would never respond — honestly or otherwise — to such questionnaires (except perhaps to chide others for responding). But I thought it was worth mentioning because certain social networks — particularly Facebook — seem positively overrun with these data-harvesting schemes. What’s more, I’m constantly asking friends and family members to stop participating in these quizzes and to stop urging their contacts to do the same.

On the surface, these simple questions may be little more than an attempt at online engagement by otherwise well-meaning companies and individuals. Nevertheless, your answers to these questions may live in perpetuity online, giving identity thieves and scammers ample ammunition to start gaining backdoor access to your various online accounts.
