Chart of recent hacks. "Lazarus" is a NK hacker group.

Every year respected cybersecurity outlet Group-IB releases an annual report, and according to TheNextWeb which obtained an advance summary of their latest - North Korea is to blame for the majority of major cryptocurrency exchange hacks.The date range covered is Feb 2018 to Sept 2018, where $882 million worth of cryptocurrency was stolen, and North Korea is getting credit for $571 million of it.Problem is, as soon as the words "North Korea" come up, everyone focuses on who did it, instead of how they did it.The most alarming part is - the methods used aren't very sophisticated.the report says.Let's be clear at what we're looking at here - incompetence within the exchanges, and poorly trained employees.Every method listed above involves a human within an exchange making amateur-level mistakes - not actual security holes in their networks. Whether it be opening an e-mail attachment that turns out to be malware, or "social engineering" which is a nice way to say - someone simply talked someone within the exchange to let them into someone else's account.Which makes me wonder - sure, i'm convinced North Korea has state funded operations dedicated to stealing cryptocurrency - i'm definitely not arguing their innocence.But when the exchanges are falling for old, simple scams leading to massive amounts of stolen funds - you have to wonder if they'd even admit it if the suspect was actually a 14 year old wanna-be hacker. A quick way to distract the public from where they went wrong, would be to switch the conversation to the hot topic of North Korea. Remember, it's in-part these exchanges "internal investigations" coming to these conclusions.But the fact is, blame here falls directly on these exchanges whichEven if North Korea was behind all of these - at best, they just happened to do it first. If getting past exchange security is truly this easy - someone was going to do it eventually.
