Dropbox has been added to the listing of firms which have fallen prey to phishing assaults.
The corporate introduced this week that, on October 14, risk actors impersonating as CircleCI gained entry to Dropbox worker credentials and stole 130 of its GitHub code repositories. GitHub alerted Dropbox to the suspicious habits, which had begun the day past.
The code accessed contained some credentials, particularly API keys utilized by Dropbox builders, the corporate stated. The code and the encircling knowledge additionally included a couple of thousand names and e-mail addresses belonging to Dropbox staff, present and previous clients, gross sales leads and distributors.
Nonetheless, Dropbox emphasised in a weblog publish, that “nobody’s content material, passwords, or fee info was accessed, and the difficulty was rapidly resolved.”

The corporate additionally reported that its core apps and infrastructure have been unaffected, as their entry is much more restricted and strictly managed.
“We imagine the danger to clients is minimal,” Dropbox stated. Nonetheless, the corporate stated, “We’re sorry we fell brief.”
Refined phishing
The announcement signifies that, regardless of consciousness and coaching, phishing stays a major (and profitable) technique for cyberattackers. In reality, a brand new report from Netskope out right this moment reveals that, whereas customers are warier on the subject of recognizing phishing makes an attempt in emails and textual content messages, they’re more and more falling prey to phishing by way of web sites, blogs and third-party cloud apps.
“In right this moment’s evolving risk panorama, individuals are inundated with messages and notifications, making phishing lures exhausting to detect,” Dropbox wrote. “Risk actors have moved past merely harvesting usernames and passwords, to harvesting multifactor authentication codes as effectively.”
The most effective educated staff nonetheless fall prey
Safety leaders weighing in on the information emphasised the significance of continued coaching and consciousness amidst more and more savvier assaults and scaled-up methods.
“Attackers right this moment appear to be transferring in direction of compromising ‘ecosystems.’ They need to have the ability to compromise apps which have huge consumer bases (like Dropbox) and the best way they’re doing that’s by trying to compromise the folks in energy: The builders,” stated Abhay Bhargav, CEO and founding father of AppSecEngineer, a safety coaching platform.
This explicit marketing campaign focused Dropbox builders and/or devops crew members, he defined. Attackers arrange phishing websites “masquerading” as CircleCI. The assault phished builders and stole their GitHub credentials.
Attackers compromised a developer’s entry and used that to steal their API token that may very well be used to entry some metadata round Dropbox’s staff, clients and distributors.
“That is an attention-grabbing evolution of phishing, as it’s oriented in direction of extra technical customers,” stated Bhargav. “This eliminates the parable that solely non-tech customers fall for phishing assaults.”
Matt Polak, CEO and founding father of the cybersecurity agency, Picnic Company, agreed that this refined social engineering assault proves that even probably the most well-trained staff may be compromised.
To cut back danger, organizations ought to, first, have the aptitude to watch and cut back their firm and worker OSINT framework publicity, as attackers want this knowledge to craft their assaults, he stated.
Secondly, firms want to have the ability to “determine and block attacker infrastructure and accounts that impersonate them or a trusted third get together earlier than these may be leveraged in opposition to their folks,” stated Polak.
What precisely occurred?
Tens of millions of builders retailer and handle supply code in GitHub. In September, the corporate’s safety crew realized that risk actors impersonating CircleCI — a well-liked steady integration and code product — had focused GitHub customers by way of phishing to reap consumer credentials and two-factor authentication.
The identical scenario occurred with Dropbox, which makes use of GitHub to publish its public and a few of its non-public repositories. The corporate additionally makes use of CircleCI for choose inner deployments. GitHub credentials can be utilized to log in to CircleCI.
In October, a number of Dropboxers acquired phishing emails impersonating CircleCI with the intent of concentrating on GitHub accounts, Dropbox reported. Its techniques routinely quarantined a few of these emails, however others landed in inboxes.
These “legitimate-looking” emails directed customers to go to a pretend CircleCI login web page, enter their GitHub username and password, after which use their {hardware} authentication key to go a one-time password (OTP) to the malicious website.
Succeeding, risk actors received entry to 130 Dropbox code repositories, which included copies of third-party libraries barely modified to be used by Dropbox, inner prototypes, and a few instruments and configuration information utilized by the safety crew.
Instantly upon being alerted to the suspicious exercise, the risk actor’s entry to GitHub was disabled. The Dropbox safety crew instantly coordinated the rotation of all uncovered credentials to find out whether or not buyer info (and what sort) was accessed or stolen, the corporate stated. A evaluate of logs discovered no proof of profitable abuse.
The corporate stated it additionally employed exterior forensic consultants to confirm these findings, whereas additionally reporting the occasion to the suitable regulators and regulation enforcement.
Implementing ‘phishing-resistant’ WebAuthn
To stop related future incidents, Dropbox stated it’s accelerating its adoption of WebAuthn, “at the moment the gold commonplace” of MFA that’s extra “phishing-resistant.” Quickly, the corporate’s entire atmosphere will probably be secured by this technique with {hardware} tokens or biometric elements.
“We all know it’s inconceivable for people to detect each phishing lure,” the corporate stated. “For many individuals, clicking hyperlinks and opening attachments is a basic a part of their job.”
Even probably the most skeptical, vigilant skilled can fall prey to a fastidiously crafted message delivered in the precise means on the proper time, stated Dropbox.
“That is exactly why phishing stays so efficient — and why technical controls stay the very best safety in opposition to these sorts of assaults,” the corporate stated. “As threats develop extra refined, the extra vital these controls develop into.”
