Two years earlier, the variety of leaked credentials was simply 5 billion, representing a 300% improve from 2018 to 2020. In keeping with the agency, the variety of leaked credentials was rising yearly and would proceed to extend within the coming years.
Digital Shadows additionally discovered that state-sponsored attackers, hacktivists, and ransomware gangs have leveraged account takeover (ATO) assaults utilizing stolen credentials.
Simply guessable and exploitable person credentials are nonetheless extensively widespread
The mid-June 2022 report by Digital shadows discovered that the highest 50 commonest passwords had been simple to guess. Some embrace combos of the identify ‘password’ with some unforgettable numbers.
Equally, using ‘123456’ as a password was quite common, accounting for 0.46% or no less than as soon as in each 200 passwords. Keyboard combos resembling ‘qwerty’ or ‘1q2w3e’ had been additionally prevalent.
Subsequently, the highest 100 commonest passwords accounted for two% of the leaked person credentials.
Moreover, 49 out of fifty commonest passwords might be cracked in lower than a second in offline assaults utilizing free or inexpensive exploitation instruments obtainable on the darkish internet.
Nonetheless, including a particular character (@,_,#) to a easy 10-character password elevated the offline crack time by 90 minutes, whereas including two particular characters elevated the time by 2 days and 4 hours.
Moreover, the Digital Shadows Photon Analysis crew discovered a staggering quantity of plaintext passwords accounting for 88.7% of stolen passwords within the database.
Nonetheless, they didn’t clarify the proportion of the leaked passwords stolen in hashed format and decrypted by the attackers earlier than itemizing. Consequently, they prompt that the full variety of stolen passwords is perhaps increased than reported.

Grajek says that attackers might pivot a username with OSINT and uncover the compromised office.
“From there it’s only a matter of logging onto the customers’ account in some type, dropping in a RAT (Distant Entry Trojan), after which start the cyber kill chain of lateral motion and privilege escalation. It’s crucial that an enterprise follow Zero Belief and robust id governance which assist determine anomalies in person privileges,” Grajek mentioned.
Darkish internet marketplaces expanded in measurement and class
Cybercriminals rely upon the darkish internet to get rid of their stolen person credentials. The Digital Shadows report discovered that darkish internet marketplaces proceed increasing and providing extra exploitation instruments, malware, and companies.

Morgan mentioned leaked person credentials embrace these of workers, clients, servers, and IoT units. He added that the breaches might have been mitigated by stronger passwords and avoiding password reuse throughout totally different accounts.
Digital Shadows attributed rising ATO assaults to a rise within the common person’s digital footprint, authentication blind spots by the shortage of consistency in authentication, and the failure to safe compromised accounts on time.
Kim DeCarlis, CMO at PerimeterX, famous that the cyber menace panorama had modified, with internet assaults being a part of an built-in cybercrime cycle, with every propagating the opposite prolonging the assault cycle.
“The entrance door to an online app is a sound person identify and password, and it’s eye-opening to study the variety of credential pairs obtainable on the darkish internet,” DeCarlis mentioned. “Stopping the theft, validation, and fraudulent use of account and id data must be a first-rate focus for all on-line companies.”
