Deleted Facebook Cybercrime Groups Had 300,000 Members

April 16, 2018

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

April 9, 2018

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.

A KrebsOnSecurity series on how easy big-three credit bureau Equifax makes it to get detailed salary history data on tens of millions of Americans apparently inspired a deeper dive on the subject by Fast Company, which examined how this Equifax division has been one of the company’s best investments.

Flash Player is Dead, Long Live Flash Player!

August 2, 2017

Adobe last week detailed plans to retire its Flash Player software, a cross-platform browser plugin so powerful and so packed with security holes that it has become the favorite target of malware developers. To help eradicate this ubiquitous liability, Adobe is enlisting the help of Apple, Facebook, Google, Microsoft and Mozilla. But don’t break out the bubbly just yet: Adobe says Flash won’t be put down officially until 2020.

SSA: Ixnay on txt msg reqmnt 4 e-acct, sry

August 16, 2016

The U.S. Social Security Administration says it is reversing a newly enacted policy that required a cell phone number from all Americans who wished to manage their retirement benefits at ssa.gov. The move comes after a policy rollout marred by technical difficulties and criticism that the new requirement did little to prevent identity thieves from siphoning benefits from Americans who hadn’t yet created accounts at ssa.gov for themselves.

Password Re-user? Get Ready to Get Busy

June 6, 2016

In the wake of megabreaches at some of the Internet’s most-recognized destinations, don’t be surprised if you receive password reset requests from numerous companies that didn’t experience a breach: Some big name companies — including Facebook and Netflix — are in the habit of combing through huge data leak troves for credentials that match those of their customers and then forcing a password reset for those users.

China Censors Facebook.net, Blocks Sites With “Like” Buttons

April 28, 2015

Chinese government censors at the helm of the “Great Firewall of China” appear to have errantly blocked Chinese Web surfers from visiting pages that call out to connect.facebook.net, a resource used by Facebook’s “like” buttons. While the apparent screw-up was quickly fixed, the block was cached by many Chinese networks — effectively preventing millions of Chinese Web surfers from visiting a huge number of sites that are not normally censored.

Android Botnet Targets Middle East Banks

April 2, 2014

I recently encountered a botnet targeting Android smartphone users who bank at financial institutions in the Middle East. The crude yet remarkably effective mobile bot that powers this whole operation comes disguised as one of several online banking apps, has infected more than 2,700 phones, and has intercepted at least 28,000 text messages.

How Many Zero-Days Hit You Today?

December 5, 2013

On any given day, nation-states and criminal hackers have access to an entire arsenal of zero-day vulnerabilities — undocumented and unpatched software flaws that can be used to silently slip past most organizations’ cyber defenses, new research suggests. That sobering conclusion comes amid mounting evidence that thieves and cyberspies are ramping up spending to acquire and stockpile these digital armaments.
