A “compilation of many breaches” – COMB for short – has been leaked on the cyber-underground, according to researchers. The so-called COMB contains a staggering 3.27 billion unique combinations of cleartext email addresses and passwords.
“On February 2, 2020, user Singularity0x01 created a thread on the popular English-language cybercriminal forum RaidForums titled ‘Compilation of Many Breaches (COMB) 3.8Billion (Public),'” Ivan Righi, cyber-threat intelligence analyst at Digital Shadows, said.'
How Serious is the COMB Data Dump?
Dustin Warren, senior security researcher at SpyCloud, also took a look at the data and determined that the login combos have been in Dark Web circulation for some time.
How to Mitigate COMB and Password Attacks
As always, implementing multifactor authentication (MFA) and maintaining good password hygiene (strong, unique passwords for all accounts and regular password rotation) can prevent much of the potential fallout from being caught up in this incident.
