Text of the page (random words):
ssuing bank 29 vendors such as uber have been mandated by the bank to amend their payment processing systems in compliance with this two factor authentication rollout 30 31 32 united states edit details for authentication for federal employees and contractors in the u s are defined in homeland security presidential directive 12 hspd 12 33 it regulatory standards for access to federal government systems require the use of multi factor authentication to access sensitive it resources for example when logging on to network devices to perform administrative tasks 34 and when accessing any computer using a privileged login 35 nist special publication 800 63 3 discusses various forms of two factor authentication and provides guidance on using them in business processes requiring different levels of assurance 36 in 2005 the united states federal financial institutions examination council issued guidance for financial institutions recommending financial institutions conduct risk based assessments evaluate customer awareness programs and develop security measures to reliably authenticate customers remotely accessing online financial services officially recommending the use of authentication methods that depend on more than one factor specifically what a user knows has and is to determine the user s identity 37 in response to the publication numerous authentication vendors began improperly promoting challenge questions secret images and other knowledge based methods as multi factor authentication due to the resulting confusion and widespread adoption of such methods on august 15 2006 the ffiec published supplemental guidelines which state that by definition a true multi factor authentication system must use distinct instances of the three factors of authentication it had defined and not just use multiple instances of a single factor 38 security weaknesses edit further information sim swap attack according to proponents multi factor authentication could drastically reduce the incidence of online identity theft and other online fraud because the victim s password would no longer be enough to give a thief permanent access to their information however many multi factor authentication approaches remain vulnerable to phishing 39 40 man in the browser and man in the middle attacks 41 to counter phishing attacks users should not share their verification codes with anyone 42 and many web application providers will place an advisory in an e mail or sms containing a code 43 clarification needed in may 2017 o2 telefónica a german mobile service provider confirmed that cybercriminals had exploited ss7 vulnerabilities to bypass sms based two step authentication to do unauthorized withdrawals from users bank accounts the criminals first infected the account holder s computers in an attempt to steal their bank account credentials and phone numbers then the attackers purchased access to a fake telecom provider and set up a redirect for the victim s phone number to a handset controlled by them finally the attackers logged into victims online bank accounts and requested for the money on the accounts to be withdrawn to accounts owned by the criminals sms passcodes were routed to phone numbers controlled by the attackers and the criminals transferred the money out 44 fatigue attack edit an increasingly common approach to defeating mfa is to bombard the user with many requests to accept a log in until the user eventually succumbs to the volume of requests and by mistake accepts one 45 this form of social engineering is called multi factor authentication fatigue attack also mfa fatigue attack or mfa bombing and may include other elements such as calls pretending to be from it support 46 47 48 when mfa applications are configured to send push notifications to end users an attacker can send a flood of login attempts in the hope that a user will click on accept at least once 46 in 2022 microsoft deployed a mitigation against mfa fatigue attacks with their authenticator app by optionally requiring the user to type in a number in addition to clicking approve 49 in october 2022 the us cybersecurity and infrastructure security agency cisa advised organizations using push notification mfa to move to phishing resistant mfa where they could not yet do so it recommended turning on number matching as an interim mitigation against fatigue attacks with number matching the login screen shows numbers that the user must type into the authenticator app before the request can be approved 50 cisa also recommended training users to report unrecognized or mass approval requests and having security teams look into push requests that users deny because a denied request can be a sign that the user s password has been compromised 50 in september 2022 uber security was breached by a member of lapsus using a multi factor fatigue attack 51 52 in 2024 a technology news site reported a targeted mfa bombing campaign against selected apple users who were flooded with system level password reset requests the attackers appeared to be sending the requests through apple s iforgot password reset page the volume of requests raised the possibility of a rate limiting flaw in that system 53 token reuse edit token reuse vulnerabilities are an identification and authentication failure in web applications 54 token reuse can be identified by testing reuse of old mfa tokens indicating whether or not the application is invalidating mfa codes any auth token given prior to mfa should not have permission to access sensitive resources auth tokens should only be provided after mfa verification old tokens should be invalidated 55 email verification mfa bypasses edit many web applications bypass authentication when verifying an email address if the web application does not invalidate the email verification link the verification link may be usable to bypass the mfa 56 if the verification token is sent via get request it may be saved in the browser s history 57 insufficient rate limiting edit mfa requires rate limiting to be secure without rate limiting an attacker can preform an arbitrary number of auth requests attempting different codes until they eventually get access 58 even with a rate limit attackers may try to limit the flow rate of requests to just under the limit threshold with a single thread to maximize the rate of attempts 59 alternatively an attacker may try to bypass the rate limit all together if the rate limit is tied to a session id or request token the attacker may generate new sessions or request tokens to reset the limit if tied to ip the attacker may rotate their ip with a tool such as burp suite s ip rotator 60 implementation edit many multi factor authentication products require users to deploy client software to make multi factor authentication systems work some vendors have created separate installation packages for network login web access credentials and vpn connection credentials for such products there may be four or five different software packages to push down to the client pc in order to make use of the token or smart card this translates to four or five packages on which version control has to be performed and four or five packages to check for conflicts with business applications if access can be operated using web pages it is possible to limit the overheads outlined above to a single application with other multi factor authentication technology such as hardware token products no software must be installed by end users citation needed some studies have shown that poorly implemented mfa recovery procedures can introduce new vulnerabilities that attackers may exploit 61 there are drawbacks to multi factor authentication that are keeping many approaches from becoming widespread some users have difficulty keeping track of a hardware token or usb plug many users do not have the technical skills needed to install a client side software certificate by themselves generally multi factor solutions require additional investment for implementation and costs for maintenance most hardware token based systems are proprietary and some vendors charge an annual fee per user deployment of hardware tokens is logistically challenging hardware tokens may get damaged or lost and issuance of tokens in large industries such as banking or even within large enterprises needs to be managed in addition to deployment costs multi factor authentication often carries significant additional support costs citation needed a 2008 survey 62 of over 120 u s credit unions by the credit union journal reported on the support costs associated with two factor authentication in their report software certificates and software toolbar approaches clarification needed were reported to have the highest support costs research into deployments of multi factor authentication schemes 63 has shown that one of the elements that tend to impact the adoption of such systems is the line of business of the organization that deploys the multi factor authentication system examples cited include the u s government which employs an elaborate system of physical tokens which themselves are backed by robust public key infrastructure as well as private banks which tend to prefer multi factor authentication schemes for their customers that involve more accessible less expensive means of identity verification such as an app installed onto a customer owned smartphone despite the variations that exist among available systems that organizations may have to choose from once a multi factor authentication system is deployed within an organization it tends to remain in place as users invariably acclimate to the presence and use of the system and embrace it over time as a normalized element of their daily process of interaction with their relevant information system while the perception is that multi factor authentication is within the realm of perfect security roger grimes writes 64 that if not properly implemented and configured multi factor authentication can in fact be easily defeated history edit a self contained rsa securid model in 2013 kim dotcom claimed to have invented two factor authentication in a 2000 patent 65 and briefly threatened to sue all the major web services however the european patent office revoked his patent 66
