- Basecamp was proven ready to handle a stuffing attack, ended it within an hour with minimal rupture.
- This is the second large-scale stuffing attack in the last few days, and it’s certain that there will be more to follow.
- People are once again urged to reset passes, use password managers, and enable 2FA, but many still don’t.
Basecamp has successfully defended against a large-scale credential stuffing attack that took place on January 29 and lasted for about an hour. According to a relevant blog post announcement by the company’s CTO, only about a hundred of user accounts were compromised, out of the 3 million that are registered with the Chicago-based project management and team communication platform. From the detection of the logins surge, the IT security team of Basecamp counted approximately 30000 attempts to access accounts, originating from a wide range of IP addresses.
The initial response was to block the IPs that were associated with the attackers, and the second phase was to enable a CAPTCHA and bring an end to the incident. The 124 people that had their accounts breached by the stuffing attack were reset, and an email to inform them of the fact was circulated in the following day. As the CTO of Basecamp, David Heinemeier Hanson stated: “All of the unauthorized access was gained using the correct username and password for the account. It’s highly likely that these credentials were obtained from one of the big breaches, like those collected in combos like Collection #1, Anti Public, or Exploit.in. All the affected accounts showed as “owned” on haveibeenpwned.com.”
In the wake of the Collection #1 account leaks, there will be many stuffing attacks like this one. Only three days ago, we reported a similar attack that targeted DailyMotion and lasted for six days, while more platforms are bound to follow suit as the particular credentials collection compromised about 773 million email addresses and the corresponding passwords. That said, the only way to protect yourself from future stuffing attacks is to check your email on “haveibeenpwned.com”, figure out if you’re included in the latest data dumps, and reset your passwords immediately. Also, as always, we advise using a password manager that will let you easily manage many different passes, and enable two-factor authentication wherever that is offered.
