Sextortion and leaked passwords

Here’s an interesting article by Brian Krebs: Sextortion Scam Uses Recipient’s Hacked Passwords

The scammer claims to have made a video of the intended victim watching porn, and threatens to send it to their friends unless payment is made. Not particularly novel: the twist with this one is that it “references a real password previously tied to the recipient’s email address.” Krebs suggests that the scammer is using a script to extract passwords and usernames from a known data breach from at least ten years ago.

The giveaway is that very few people are likely to be using the same password now – and it’s unlikely that there are that many people receiving the email who might think that such a video could have been made. Still, it seems that some people have actually paid up, and it’s possible that a more convincing attack might be made sending a more recent password to a given email address, and perhaps using a different type of leverage.

Tech support scam article for ESET

Here’s an article by me for ESET: Tech support scams and the call of the void

“Christopher Burgess for Security Boulevard on what happens When Scammers Fill the Tech Support Void … says: “I still haven’t figured out why those companies that provide tech support tend to hide the connectivity to these saviors of their brand in the weeds of the website, but they do, and we search—and sometimes we strike gold.”

However, I don’t think the reluctance of companies to draw attention to their support services is too much of a mystery…”

There may be persuasive reasons why providers are reluctant to engage directly with their customers, but the consequences may be grim for both provider and customer.

And here are a couple of other scam-related stories you may find of interest:

Microsoft on support scams – plus, assessing gullibility

Erik Wahlstrom for Microsoft talks about tech support scams, the volume of complaints Microsoft receives, and the partnerships it has built in an effort to reduce their impact. Worth reading. Teaming up in the war on tech support scams. Some commentary and basic advice from Graham Cluley: Reports of tech support scams rocket, earning handsome returns for fraudsters.

Homeland Security News Wire: Tool measures individuals’ likelihood to fall for internet scams. Taking a look at the actual survey, I find it hard to assess the validity of the questions, despite (or perhaps because of) my academic and professional background. There are a lot of questions there I simply wouldn’t choose to answer. Still, the paper is interesting: We will make you like our research: The development of a susceptibility-to-persuasion scale [Update: commentary from ESET: This test will tell you how likely you are to fall for fraud]
