Okta Warns of Unprecedented Surge in Proxy-Driven Credential Stuffing Attacks

Id and obtain administration (IAM) providers company Okta has warned of a spike in the “frequency and scale” of credential stuffing attacks aimed at on the internet expert services.

These unparalleled attacks, observed about the last thirty day period, are said to be facilitated by “the broad availability of residential proxy companies, lists of previously stolen credentials (‘combo lists’), and scripting resources,” the firm explained in an alert revealed Saturday.

The conclusions establish on a recent advisory from Cisco, which cautioned of a world wide surge in brute-drive attacks concentrating on several units, like Virtual Private Network (VPN) expert services, web application authentication interfaces, and SSH products and services, due to the fact at minimum March 18, 2024.

“These attacks all look to be originating from TOR exit nodes and a vary of other anonymizing tunnels and proxies,” Talos pointed out at the time, adding targets of the attacks comprise VPN appliances from Cisco, Look at Issue, Fortinet, SonicWall, as well as routers from Draytek, MikroTik, and Ubiquiti.

Okta stated its Identification Danger Study detected an uptick in credential stuffing activity in opposition to person accounts from April 19 to April 26, 2024, from possible related infrastructure.

Credential stuffing is a kind of cyber attack in which credentials attained from a knowledge breach on just one support are used to attempt to signal in to a different unrelated services.

Alternatively, these kinds of credentials could be extracted through phishing attacks that redirect victims to credential harvesting pages or by way of malware campaigns that install data stealers on compromised units.

“All the latest attacks we have observed share a person function in widespread: they depend on requests getting routed by way of anonymizing providers such as TOR,” Okta claimed.

“Tens of millions of the requests ended up also routed by a range of household proxies including NSOCKS, Luminati, and DataImpulse.”

Household proxies (RESIPs) refer to networks of authentic consumer products that are misused to route website traffic on behalf of having to pay subscribers with out their knowledge or consent, thereby allowing for danger actors to conceal their malicious website traffic.

This is ordinarily reached by putting in proxyware tools on computers, cellular telephones, or routers, proficiently enrolling them into a botnet which is then rented to buyers of the services who wish to anonymize the resource of their website traffic.

“In some cases a person machine is enrolled in a proxy network simply because the user consciously chooses to download ‘proxyware’ into their machine in exchange for payment or some thing else of benefit,” Okta explained.

“At other instances, a consumer gadget is contaminated with malware without having the user’s expertise and turns into enrolled in what we would generally describe as a botnet.”

Previous thirty day period, HUMAN’s Satori Risk Intelligence crew exposed about two dozen malicious Android VPN applications that transform mobile products into RESIPs by implies of an embedded computer software improvement package (SDK) that integrated the proxyware features.

“The net sum of this activity is that most of the targeted visitors in these credential stuffing attacks look to originate from the cellular units and browsers of everyday users, somewhat than from the IP place of VPS companies,” Okta explained.

To mitigate the risk of account takeovers, the corporation is recommending that businesses enforce people to swap to sturdy passwords, permit two-factor authentication (2FA), deny requests originating from areas exactly where they really don’t operate and IP addresses with inadequate standing, and add support for passkeys.
