Twitter Hacked within Bitcoin Scam
It started with a single weird tweet. Another then. Quickly, one of the most notable accounts on Twitter had been all sending out exactly the same message;
We am giving back again to the community.
All Bitcoin delivered to the deal with below will undoubtedly be sent back doubled! In the event that you send $1,000, I’ll send back $2,000. Only achieving this for half an hour.

Are Apple company, Elon Musk, Barrack Obama, Uber, Joe Biden, and a bunch of others taking part in an extremely transparent bitcoin scheme?
No. Needless to say, not. The issue was whether individual accounts had been compromised or if something deeper had been going on.
User Account Protections
These visible accounts are primary targets for cybercriminals. They will have a broad achieve and even a short compromise of one of the accounts would significantly enhance a hacker’s popularity in the underground.
That’s exactly why these accounts leverage the protections offered by Twitter to keep their accounts safe.
Whilst it’s think that one or 2 of these accounts didn’t take these actions, it’s unlikely that tons of these did highly. Just what exactly happened?
As with any public attack, the Twitter-verse (ironically) was abuzz with speculation. That speculation ramped up when Twitter took the reasonable step of preventing any Verified account from tweeting for approximately three hours.
This helped prevent any addition scam tweets from being published but additionally raised the profile of the attack further.
While some might shy from raising the profile of an attack, this is reasonable trade off to avoid further harm to affected accounts also to assist in preventing the attack from taking more ground.
This move also provided a hint in regards to what was going on. If individual accounts were being attacked, it’s unlikely that kind of move would’ve done much to avoid the attacker from gaining access. However, if the attacker was accessing a backend system, this mitigation will be effective.
Had Twitter itself been hacked?
When imagining attack scenarios, a primary breach of the primary service is really a scenario that’s often examined comprehensive. For this reason it’s perhaps one of the most planned for scenarios also.
Twitter—like any ongoing company; has challenges using its systems however they center around content moderation&hellip primarily;their backend security is first class.
An exemplory case of this an incident in 2018. Twitter engineers made a blunder that meant anyones password might have been exposed within their internal logs. In case just, Twitter urged everyone to reset their password.
While possible, it’s unlikely that Twitter’s backend systems were breached. There is a easier potential explanation: insider access.
Quickly following the attack, some in the security community noticed a screenshot of an internal support tool from Twitter surfacing in underground discussion forums. This rare inside view, showed what were just what a support team member would see Twitter.
This kind of access is dangerous. Very dangerous.
Joseph Cox’s article detailing the hack includes a key quote,
“We used the rep that done all of the work with us&rdquo literally;
What remains unclear is usually whether it is a situation of interpersonal engineering (tricking the privileged insider into using action) or perhaps a malicious insider (someone inner motivated to strike the machine).
The difference is essential for other defenders on the market.
The investigation is ongoing, and Twitter continues to offer updates via @TwitterSupport;
Our investigation continues to be ongoing but here’s what we realize so far:

If this attack was conducted through social engineering. The security team at Twitter should implement additional processes and controls to make sure that it doesn’t again happen.
This will be what your team must also look from. While password resets, account closures, information transfers, and other essential processes are at specific risk of interpersonal engineering, financial transactions are usually atop the cybercriminals focus on list.
Adding additional aspect channel confirmations, additional methods for verifications, company and clear approvals, along with other process steps might help organizations mitigate these kinds of social engineering episodes.
If the attack actually is from the malicious insider. Defenders have to have a different approach.
Malicious insiders are both a security problem and an recruiting one.
From the security perspective, two key principles help mitigate the potential of the attacks;
Making sure individuals only have the technical access had a need to complete their assigned tasks and only that access is paramount to limiting this potential attack. Combined with smart separation of duties (one individual to request a big change, another to approval it), this reduces the chance of the attacks causing harm significantly.
The other—rather than spoken of&mdash often; side of the attacks is the justification behind the malicious intent. Some individuals are malicious so when presented with a chance just, they shall take it.
Other times, it’s a worker that feels neglected, passed over, or is disgruntled in a few other way. A solid internal community, communication regularly, and a solid HR program might help address these issues before they escalate to the stage where aiding a cybercriminal becomes an enticing choice.
Underlying this whole situation is really a more challenging issue; the known degree of access that support must any given system.
It’s an easy task to think about a Twitter account as “yours”. It’s not. It’s section of a system that’s run by way of a company that must monitor the fitness of the system, reaction to support issues, and aid police when required.
All of the requirements necessitate an even of access that a lot of don’t about think.
How often are you currently sharing sensitive information via direct message? Those messages are likely accessible by support.
What’s to avoid them from accessing any given account or message at any right time? We don’t know.
Hopefully Twitter—and others—have clear guardrails (technical and policy-based) set up to avoid abuse of support access plus they regularly audit them.
It’s a difficult balance to strike. User trust reaches stake however the viability of owning a service also.
Clear, transparent controls and policies will be the keys to success here.
Abuse could be internal or external. Support teams routinely have privileged access but are on the list of lowest paid in the business also. Support—outside the SRE community—sometimes appears as basic level usually.
These teams have highly sensitive access so when things go south, can perform plenty of harm. Again, the principles of least privilege, separation of duties, and a solid set of policies might help.
In the coming days additional information of the attack will surface. For the time being, the city continues to be struggling to reconcile the known degree of access gained and how it had been used.
Getting usage of a few of the world most prominent accounts and conducting a bitcoin scam? In line with the bitcoin transactions, it seems the cybercriminals made off with just a little over $100,000 USD. Not insignificant but there have been other opportunities surely?
Occam’s razor can again help here. Bitcoin scams and coin miners will be the most direct method fo cybercriminals to capitalized on the efforts. Given the visible nature of the attack, enough time before discovery would be sure. This may have already been the “safest” bet for the criminal(s) to produce a benefit from this hack.
In the finish, it’s a lesson for users of internet sites and other services; invest the every one of the reasonable security precautions even, you are counting on the ongoing service itself to greatly help protect you. That might not necessarily hold true.
For providers and defenders, it’s a harsh reminder that the tooling you set up to perform your service could be its biggest risk…a risk that’s overlooked and underestimated often.
In the finish, Marques Brownlee sums it up succinctly;
Don’t send Bitcoin to strangers.
