A large information breach could have affected some 5.4 million Twitter person accounts containing private info in Europe and the US. The info was reportedly stolen utilizing an API vulnerability and shared totally free on a hacker discussion board. Although the vulnerability has reportedly been fastened, one other huge, even doubtlessly extra vital information dump of hundreds of thousands of Twitter information has additionally been disclosed by safety researchers.
In line with a report from Bleeping Pc, the info consists of scraped public info in addition to personal cellphone numbers and e-mail addresses that aren’t meant to be public. A number of menace actors had been using a bug to steal personal info.
That bug was found by HackerOne throughout a bug bounty earlier this yr, and apparently addressed, nevertheless it stays unclear if that disclosure had additionally been leaked.
“This breach showcases how rapidly criminals transfer every time there’s a vulnerability, notably in a big social media web site,” defined Javvad Malik, safety consciousness advocate at KnowBe4, through an e-mail. “With a lot info disclosed, criminals may fairly simply use it to launch convincing social engineering assaults in opposition to customers. This could possibly be not solely to focus on their Twitter accounts, but in addition through impersonating different providers equivalent to on-line purchasing websites, banks, and even tax workplaces.”
Safety researcher Avishai Avivi, CISO at SafeBreach, warned that API assaults are going to turn out to be extra outstanding within the close to future and plague the businesses counting on APIs for years to come back. It’s because APIs are meant for use by programs to speak with one another and trade huge quantities of knowledge – and because of this, these interfaces characterize an alluring goal for malicious actors to abuse.
“Whereas API weaknesses could also be more difficult to find, as soon as an adversary features entry to an improperly designed API, they primarily have direct entry to the group’s databases,” stated Avivi. “That is additionally why when a breach happens via an API, we are going to see hundreds of thousands of information being impacted.”
Furthermore, API vulnerabilities additionally don’t want human interplay – equivalent to clicking on a malicious hyperlink, or falling for a phishing e-mail).
“The constructive aspect of API vulnerabilities is that they’re sometimes distinctive to the group utilizing it. Not like conventional software program vulnerabilities, the malicious actor can not use the identical vulnerability to assault a unique group,” added Avivi.
That’s doubtless of little consolation for the hundreds of thousands of Twitter customers whose information could now be provided totally free on the darkish internet.

The knowledge from “scraped information” had apparently included cellphone numbers, Fb IDs, names, areas, DOBs, and e-mail addresses.
“Each single one of many 533 million Facebooks customers whose info was revealed on hacking boards confronted potential follow-up phishing scams exploiting their uncovered PII (Private Identifiable Data) within the pursuit of extra priceless credentials,” stated John Stevenson, product director at cybersecurity agency Cyren, through an e-mail.
“So, while the preliminary information leak was again in 2021, it is nonetheless encouraging to see fines being issued retrospectively,” Stevenson added. “Hopefully, the implications right here will encourage different enterprises to adjust to cyber laws and observe finest practices to keep away from a mercenary penalty sooner or later, notably given cyber insurers more and more setting a better bar for due diligence to keep away from extortionate payouts like this one.”
It’s too early to know if Twitter shall be going through an analogous positive for its current information breach.
