Bitcoin Extortion Group DD4BC Now Targeting Financial Services

An anonymous reader writes: Akamai is detailing the activities of DD4BC, a cyber-extortionist group that has launched distributed denial-of-service (DDoS) attacks against numerous organizations and demanded Bitcoin payments to stop the attacks. The group is sending ransom emails requiring payments of 25 to 100 Bitcoin, which is about $6,000 — $24,000 (€5,350 — €21,400). Social media shaming is also part of the deal, threatening to expose the DDOS on Twitter if payment is not made.

Thanks for the advice, isis.

The best strategy is to ignore them

[timholman]

Publishing this story is doing no favors to anyone. As many others have pointed out in the past, if your company receives one of these emails, the best strategy is to ignore it.

These extortionists will send emails to hundreds or thousands of different companies, but they can't DDOS all of them at once. Furthermore, they have no idea if their emails even make it past the spam filters of their targets. So how do they decide who to DDOS? By seeing who responds to the blackmail message. Once you respond, and they know you are listening to them, you are now in their sights - not just this time, but the next time they decide to shake you down.

Ignore them. If they DDOS you, deal with it, but never acknowledge their demands. They can never be certain that you are receiving their emails, and if you never respond to them, eventually they'll move on to someone else.

if justice is more brutal than the crime, then it is not justice

all punishments for all crimes must be less sever than the crime in question

or society itself generates brutality and crime

chopping off hands for theft in sharia law, caning for vandalism in singapore, or locking a guy up for years for smoking pot in the USA: none are not justice

and you, and people who think like you, asking for death for petty extortion, you are worse criminals than the crime you hate

What's the point of "shaming"?

[cdrudge]

Social media shaming is also part of the deal, threatening to expose the DDOS on Twitter if payment is not made.

What would be the point of this? "We're going to shame you to show that we're trying to extort you and you're not giving in." Is this suppose to cause peer pressure to force the financial institutions to settle? Or to garner sympathy for the attackers?

It's not logical because you're not dealing with mature people. Keep in mind that these guys are almost certainly a group of young, socially maladjusted individuals. To a professional criminal, 50 BTC is chump change, but to a group of kids who want BTC to buy drugs without Mom and Dad finding out, it's a lot of cash.

To a kid who grew up on social media, social shaming of your victim might seem an extremely potent weapon, just like school bullying. The rest of us will just scratch our heads and shrug our shoulders.

so don't read my comments. this isn't a fucking doctoral dissertation, it's a comment board. adjust your expectations

to me it's a sign of a brittle mind, to be so bothered by punctuation. it is of benefit to me and everyone else therefore to weed people like you out of the discussion

I am perfectly capable of standard punctuation. But nowadays I do all lowercase on purpose. Exactly because of comments like yours.

good riddance
