Key Indicators in CloudTrail Logs for Stolen API Keys

As cloud infrastructure turns into the spine of recent enterprises, guaranteeing the safety of those environments is paramount. With AWS (Amazon Internet Companies) nonetheless being the dominant cloud it is vital for any safety skilled to know the place to search for indicators of compromise. AWS CloudTrail stands out as a vital instrument for monitoring and logging API exercise, offering a complete document of actions taken inside an AWS account. Consider AWS CloudTrail like an audit or occasion log for the entire API calls made in your AWS account. For safety professionals, monitoring these logs is crucial, notably relating to detecting potential unauthorized entry, reminiscent of by way of stolen API keys. These methods and lots of others I’ve discovered by way of the incidents I’ve labored in AWS and that we constructed into SANS FOR509, Enterprise Cloud Forensics.

1. Uncommon API Calls and Entry Patterns

A. Sudden Spike in API Requests

One of many first indicators of a possible safety breach is an sudden enhance in API requests. CloudTrail logs each API name made inside your AWS account, together with who made the decision, when it was made, and from the place. An attacker with stolen API keys may provoke numerous requests in a short while body, both probing the account for data or making an attempt to use sure providers.

What to Look For:

  • A sudden, uncharacteristic surge in API exercise.
  • API calls from uncommon IP addresses, notably from areas the place reputable customers don’t function.
  • Entry makes an attempt to all kinds of providers, particularly if they don’t seem to be usually utilized by your group.

Notice that Guard Responsibility (if enabled) will mechanically flag these sorts of occasions, however you must be watching to seek out them.

B. Unauthorized Use of Root Account

AWS strongly recommends avoiding using the foundation account for day-to-day operations because of its excessive degree of privileges. Any entry to the foundation account, particularly if API keys related to it are getting used, is a big crimson flag.

What to Look For:

  • API calls made with root account credentials, particularly if the foundation account just isn’t usually used.
  • Adjustments to account-level settings, reminiscent of modifying billing data or account configurations.

2. Anomalous IAM Exercise

A. Suspicious Creation of Entry Keys

Attackers might create new entry keys to determine persistent entry to the compromised account. Monitoring CloudTrail logs for the creation of recent entry keys is essential, particularly if these keys are created for accounts that usually don’t require them.

What to Look For:

  • Creation of recent entry keys for IAM customers, notably those that haven’t wanted them earlier than.
  • Quick use of newly created entry keys, which may point out an attacker is testing or using these keys.
  • API calls associated to `CreateAccessKey`, `ListAccessKeys`, and `UpdateAccessKey`.

C. Function Assumption Patterns

AWS permits customers to imagine roles, granting them momentary credentials for particular duties. Monitoring for uncommon position assumption patterns is important, as an attacker may assume roles to pivot throughout the surroundings.

What to Look For:

  • Uncommon or frequent `AssumeRole` API calls, particularly to roles with elevated privileges.
  • Function assumptions from IP addresses or areas not usually related along with your reputable customers.
  • Function assumptions which can be adopted by actions inconsistent with regular enterprise operations.

3. Anomalous Knowledge Entry and Motion

A. Uncommon S3 Bucket Entry

Amazon S3 is usually a goal for attackers, provided that it will probably retailer huge quantities of probably delicate knowledge. Monitoring CloudTrail for uncommon entry to S3 buckets is crucial in detecting compromised API keys.

What to Look For:

  • API calls associated to `ListBuckets`, `GetObject`, or `PutObject` for buckets that don’t usually see such exercise.
  • Giant-scale knowledge downloads or uploads to and from S3 buckets, particularly if occurring outdoors of regular enterprise hours.
  • Entry makes an attempt to buckets that retailer delicate knowledge, reminiscent of backups or confidential information.

B. Knowledge Exfiltration Makes an attempt

An attacker might try to maneuver knowledge out of your AWS surroundings. CloudTrail logs might help detect such exfiltration makes an attempt, particularly if the information switch patterns are uncommon.

What to Look For:

  • Giant knowledge transfers from providers like S3, RDS (Relational Database Service), or DynamoDB, particularly to exterior or unknown IP addresses.
  • API calls associated to providers like AWS DataSync or S3 Switch Acceleration that aren’t usually utilized in your surroundings.
  • Makes an attempt to create or modify knowledge replication configurations, reminiscent of these involving S3 cross-region replication.

4. Sudden Safety Group Modifications

Safety teams management inbound and outbound visitors to AWS sources. An attacker may modify these settings to open up further assault vectors, reminiscent of enabling SSH entry from exterior IP addresses.

What to Look For:

  • Adjustments to safety group guidelines that permit inbound visitors from IP addresses outdoors your trusted community.
  • API calls associated to `AuthorizeSecurityGroupIngress` or `RevokeSecurityGroupEgress` that don’t align with regular operations.
  • Creation of recent safety teams with overly permissive guidelines, reminiscent of permitting all inbound visitors on widespread ports.

5. Steps for Mitigating the Threat of Stolen API Keys

A. Implement the Precept of Least Privilege

To attenuate the injury an attacker can do with stolen API keys, implement the precept of least privilege throughout your AWS account. Be sure that IAM customers and roles solely have the permissions essential to carry out their duties.

B. Implement Multi-Issue Authentication (MFA)

Require MFA for all IAM customers, notably these with administrative privileges. This provides a further layer of safety, making it harder for attackers to realize entry, even when they’ve stolen API keys.

C. Commonly Rotate and Audit Entry Keys

Commonly rotate entry keys and be certain that they’re tied to IAM customers who really need them. Moreover, audit using entry keys to make sure they don’t seem to be being abused or used from sudden areas.

D. Allow and Monitor CloudTrail and GuardDuty

Be sure that CloudTrail is enabled in all areas and that logs are centralized for evaluation. Moreover, AWS GuardDuty can present real-time monitoring for malicious exercise, providing one other layer of safety towards compromised credentials. Take into account AWS Detective to have some intelligence constructed on prime of the findings.

E. Use AWS Config for Compliance Monitoring

AWS Config can be utilized to watch compliance with safety greatest practices, together with the right use of IAM insurance policies and safety teams. This instrument might help determine misconfigurations that may depart your account weak to assault.

Conclusion

The safety of your AWS surroundings hinges on vigilant monitoring and fast detection of anomalies inside CloudTrail logs. By understanding the standard patterns of reputable utilization and being alert to deviations from these patterns, safety professionals can detect and reply to potential compromises, reminiscent of these involving stolen API keys, earlier than they trigger vital injury. As cloud environments proceed to evolve, sustaining a proactive stance on safety is crucial to defending delicate knowledge and guaranteeing the integrity of your AWS infrastructure.

macos – How do I discover my IP Tackle from the command line?


You are able to do the next:

Sort ifconfig or ifconfig -a. This command reveals you the record of interfaces together with their IP and MAC addresses (the latter one provided that relevant). You can even kind ifconfig en0 or ifconfig en1 for the configuration of a selected interface solely (as somebody mentioned of their solutions, en0 is usually the wired Ethernet whereas en1 is the WiFi interface).

Instead, netstat -i will record all interfaces and can present you the IP addresses you could have assigned to every of them.

Usually, when you could have SSH daemon operating on a field, it can hear on all accessible interfaces, ie. you need to use any IP tackle that is configured in your machine to connect with that machine by way of SSH (this, clearly, topic to Firewall guidelines). Should you’re after what the OS calls a Main interface and first IP tackle, you need to use the scutil command like this: 

MacBook:~ scutil
> present State:/Community/World/IPv4
 {
  PrimaryInterface : en0
  PrimaryService : C0550F84-5C07-484F-8D62-C8B90DC977D8
  Router : 10.103.4.1
}
> present State:/Community/Interface/en0/IPv4
 {
  Addresses :  {
    0 : 10.103.4.234
  }
  BroadcastAddresses :  {
    0 : 10.103.4.255
  }
  SubnetMasks :  {
    0 : 255.255.255.0
  }
}

Please notice, that the above, regardless that is a command-line command, can also be interactive (so that you run scutil after which enter its personal instructions into it). The primary present command tells you the title of the first interface for the OS (i.e. this would be the one on prime of the record in your System Preferences / Community Preferences window), in addition to the IP tackle of your default router. The second present command takes State:/Community/Interface//IPv4 argument (on this case, en0) and offers you the IP addresses assigned to it. You are on the lookout for the tackle within the Addresses array, the opposite two entries are broadcast addresses and the netmasks.

Hope that helps, but when something will not be clear, let me know.

Cybercrime Rapper Sues Financial institution over Fraud Investigation – Krebs on Safety


Cybercrime Rapper Sues Financial institution over Fraud Investigation – Krebs on Safety

A partial selfie posted by Punchmade Dev to his Twitter account. Sure, that could be a functioning handheld card skimming system, encrusted in diamonds. Beneath which are extra medallions, together with a diamond-studded bitcoin and cost card.

In January, KrebsOnSecurity wrote about rapper Punchmade Dev, whose music movies sing the praises of a cybercrime life-style. That story confirmed how Punchmade’s social media profiles promoted Punchmade-themed on-line shops promoting checking account and cost card knowledge. The topic of that piece, a 22-year-old Kentucky man, is now openly suing his monetary establishment after it blocked a $75,000 wire switch and froze his account, citing an lively regulation enforcement investigation.

With memorable hits resembling “Web Swiping” and “Million Greenback Prison” incomes hundreds of thousands of views, Punchmade Dev has leveraged his appreciable following to hawk tutorials on find out how to commit monetary crimes on-line. However till lately, there wasn’t a lot to help a conclusion that Punchmade was truly doing the cybercrime issues he promotes in his songs.

That modified earlier this yr when KrebsOnSecurity confirmed how Punchmade’s social media handles have been selling Punchmade e-commerce outlets on-line that offered entry to Cashapp and PayPal accounts with balances, software program for printing checks, in addition to private and monetary knowledge on Individuals.

Punchmade Dev’s earlier on-line store (now defunct). His Telegram channel has greater than 75,000 followers.

The January story traced Punchmade’s numerous on-line properties to a 22-year-old Devon Turner from Lexington, Ky. Reached through his profile on X/Twitter, Punchmade Dev stated they weren’t affiliated with the lawsuit filed by Turner [Punchmade’s X account provided this denial even though it has still not responded to requests for comment from the first story about him in January]. In the meantime, Mr. Turner has declined a number of requests to remark for this story.

On June 26, Turner filed a professional se lawsuit towards PNC Financial institution, alleging “illegal discriminatory and tortuous motion” after he was denied a wire switch within the quantity of $75,000. PNC Financial institution didn’t reply to a request for remark.

Turner’s grievance states {that a} follow-up name to his financial institution revealed the account had been closed because of “suspicious exercise,” and that he was now not welcome to patronize PNC Financial institution.

“The Plaintiff is a really profitable African-American enterprise proprietor, who has generated hundreds of thousands of {dollars} together with his companies, has employed 30 plus folks to work for his companies,” Turner wrote.

As reported in January, amongst Turner’s companies is a Lexington entity known as OBN Group LLC (assumed title Punchmade LLC). Enterprise incorporation paperwork from the Kentucky Secretary of State present he additionally ran a file label known as DevTakeFlightBeats Inc.

Turner’s lawsuit alleges that financial institution workers made disparaging remarks about him, suggesting the account was canceled as a result of it might be uncommon for an individual like him to have that type of cash.

A snippet from Turner’s lawsuit vs. PNC.

Extremely, Turner acknowledges that PNC advised him his account was flagged for consideration from regulation enforcement officers.

“The PNC Financial institution customer support consultant additionally defined that there was a be aware on the account that regulation enforcement could be contacted in some unspecified time in the future in time,” the lawsuit reads.

“The Plaintiff, who was not nervous in any respect about regulation enforcement being concerned as a result of nothing unlawful occurred, knowledgeable the PNC Financial institution consultant that this was one huge mistake and requested him what his choices have been,” the grievance states.

Turner’s lawsuit stated PNC advised him they might put a be aware on his account permitting him to withdraw the funds from any department, however that when he visited a PNC department and requested to withdraw your entire quantity in his account — $500,000 — PNC refused, saying the cash had been seized.

“Finally, PNC financial institution not solely refused his request to launch his funds however knowledgeable him that his funds could be seized indefinitely as [sic] PNC Financial institution,” Turner lawsuit recounts.

The Punchmade outlets promoting monetary knowledge that have been profiled within the January story are lengthy gone, however Punchmade’s Instagram account now promotes punchmade[.]cc, which behaves and appears the identical as his older store.

Punchmade’s present store, which DomainTools says was registered to a Lexington, Ky. cellphone quantity utilized by accounts below the title of Devon Turner at a number of on-line retailers.

The breach monitoring service Constella Intelligence finds the e-mail deal with related to Turner’s enterprise OBN Group LLC — obndevpayments@gmail.com — was utilized by a Devon Turner from Lexington to buy software program on-line. That file contains the Lexington, Ky. cell phone quantity 859-963-6243, which Constella additionally finds was used to register accounts for Devon Turner on the retailer Neiman Marcus, and on the house decor and style website poshmark.com.

A search on this cellphone quantity at DomainTools reveals it’s related to two domains since 2021. The primary is the aforementioned punchmade[.]cc. The opposite is foreverpunchmade[.]com, which is registered to a Devon Turner in Lexington, Ky. A replica of this website at archive.org signifies it as soon as offered Punchmade Dev-branded t-shirts and different merchandise.

Mr. Turner included his contact info on the backside of his lawsuit. What cellphone quantity did he go away? Would you consider 859-963-6243?

The closing part of Mr. Turner’s grievance features a cellphone quantity that was used to register a well-liked on-line fraud store named after Punchmade.

Is Punchmade Dev a big-time cybercriminal enabler, as his public personna would have us consider? Or is he some two-bit nitwit who has spent a lot on customized medallions that he can’t afford a lawyer? It’s arduous to inform.

However he definitively has a broad attain: His Instagram account has ~860k followers, and his Telegram channel has greater than 75,000 subscribers, all little question looking for that candy “C@sh App sauce,” which apparently has one thing to do with shifting cryptocurrencies via Money App in a method that financially rewards folks in a position and prepared to open up new accounts.

It’s extremely ironic that Punchmade sells tutorials on find out how to have nice “opsec,” a reference to “operational safety,” which within the cybercriminal context means the flexibility to efficiently separate one’s cybercriminal identification from one’s real-life identification: This man can’t even register a site title anonymously.

A replica of Turner’s grievance is accessible right here (PDF).

For extra on Punchmade, try the TikTok video How Punchmade Dev Bought Began Scamming.

Replace, Aug. 8, 8:49 a.m. ET: A reader identified that Turner additionally lately sued a Mercedes Benz dealership in Illinois, allegedly for promoting him a lemon. In that professional se grievance, Turner included the contact e-mail deal with punchmadedev@gmail.com.

3 API Safety Dangers and Suggestions for Mitigation


From the attacker’s perspective, one of the time-consuming elements of planning a community assault is the reconnaissance required to search out potential community assault vectors. Since software programming interfaces (APIs) should be uncovered to the general public, the period of time the attacker spends discovering assault vectors into the API’s community is enormously lowered, making APIs a better goal for potential breaches. The usage of APIs can improve the assault floor of a community, and, if not designed appropriately, they may end up in vital safety points.

The rise in implementing microservice architectures rather than monolithic software program architectures now makes APIs extra widespread than ever. To facilitate implementation of a zero belief technique in a community, this pervasiveness requires a targeted effort to establish API-specific vulnerabilities. On this weblog put up, which is excerpted from a lately printed paper, I current three high API safety dangers together with suggestions for mitigating them.

Earlier than delving into the highest API dangers, you will need to perceive how they’re constructed.

API Endpoints

An API supplies a programmed entry level into an software. If the appliance is designed to work together with different functions, then an API is put into place to allow that interplay. Inside every API, there are a number of software connection factors known as endpoints.

Every endpoint serves a unique objective, however they’re all linked to the identical software. The next are a couple of examples of how an API endpoint may be used:

  • logins (The required inputs for that endpoint are a username and password.)
  • password resets (The required enter would possibly solely be an e-mail, so a password reset hyperlink could be despatched.)
  • directors altering software settings (The required enter for entry may be a username and password.)
  • enabling interplay between microservices (The required inputs may be consumer IDs or different consumer data, product or order data, or complete information construction objects.)

Microservice Architectures

Over the previous decade, microservice architectures have turn out to be extra well-liked for newly designed methods in comparison with the beforehand dominant monolithic architectures.

Microservice architectures concentrate on creating many small, loosely coupled micro functions to provide a bigger software. For instance, an organization may need a product descriptions microservice, a cost processing microservice, and a login microservice. Every of those microservices could be executed and deployed independently of the others. Every microservice has its personal API and endpoints for client-to-microservice or microservice-to-microservice interactions.

The distributed, loosely coupled design of those microservice architectures enable them to have larger scalability, flexibility, and steady deployments when in comparison with monolithic architectures. In keeping with Nationwide Institute of Requirements and Know-how (NIST) particular publication (SP) 800-204, “Microservices typically talk with one another utilizing Software Programming Interfaces (APIs), which require a number of core options to help complicated interactions between a considerable variety of elements.” There are sometimes help constructions that additionally assist API ecosystems by providing options, corresponding to API gateways and service meshes. Whereas this weblog put up and the paper from which this was excerpted solely talk about APIs, the use and configuration of supporting constructions (e.g., identification entry administration [IAM] servers, API gateways, service meshes) are additionally essential to general API safety.

The rest of this put up will define three API safety dangers (third-party software program integrations, cascading failures, and elevated community assault floor) and supply suggestions for mitigating them.

Third-Celebration Software program Integrations

Description. Typically when creating new software program, together with APIs, current software program packages and libraries are used to make the design and implementation course of sooner and simpler. Nonetheless, integrating third-party software program means introducing all of the doable vulnerabilities of that software program into the brand new API that’s being constructed. Even the very best high quality code can have as much as 600 defects per million strains of code whereas common high quality code has round 6,000 defects per million strains of code. Many of those defects may end up in vulnerabilities.

Instance. Log4J is a crucial vulnerability within the Java-based logging library that was found in 2022. It permits distant code execution and the whole takeover of the sufferer’s machine. Any system that has Log4j built-in into its software program is weak to assault till the vulnerability is patched.

Suggestions. The next suggestions apply to this danger.

  1. Carry out danger assessments on all third-party software program that may be utilized in a brand new API to forestall introducing further API vulnerabilities.
  2. Keep knowledgeable concerning the newest vulnerabilities in all third-party software program that’s built-in into at the moment deployed APIs.
  3. Use automated vulnerability scanners on third-party software program if doable.
  4. Contemplate implementing a software program invoice of supplies framework to assist safe the provision chain and mitigate the dangers of utilizing third-party software program.

Cascading Failures

Description. As beforehand talked about, APIs are intently tied to microservices, that are small functions designed to carry out a particular operate. These microservices must be loosely coupled with excessive cohesion, which implies that every of them works independently or largely independently from different microservices. Designing the microservice structure with unbiased functions prevents the whole API ecosystem from shutting down if a single microservice turns into damaged or nonfunctional.

Designing the microservice structure with loosely coupled elements reduces the chance of API shut downs if a single microservice turns into damaged or nonfunctional. When one microservice’s inoperability causes points with different microservices, it’s known as cascading failures, and it must be averted to cut back the chance of DoS assaults on the API.

Instance. As illustrated in determine 1 beneath, assume a gross sales data API should name a product description API to finish a shopper request it receives from the API gateway, but in addition assume that the product description API goes down. On this case, the gross sales data microservice can now not full its request. Because of this, the gross sales data software can’t be used as a result of one other software it depends on is down.

Suggestions. The next suggestions apply to this danger.

  1. Design APIs with the objective of unfastened coupling in thoughts, together with deployment coupling, temporal coupling, and implementational coupling.
  2. Create API documentation that clearly reveals which APIs are coupled and the communication movement that occurs between coupled microservices. This documentation can be helpful for testing and troubleshooting if there are points with the API after deployment.
  3. Conduct unit testing, integration testing, and end-to-end testing to substantiate the right performance of the microservice structure in response to the documented design.
  4. Try to forestall single factors of failure within the API community by including redundancy measures in authentication and authorization factors and different community constructions.

Elevated Community Assault Floor

Description. Microservice architectures that closely use APIs have many structural variations when in comparison with monolithic architectures. These variations can usually improve the general community assault floor. Many non-microservice architectures have an internet server in a demilitarized zone (DMZ) with a backend service one layer behind it that comprises the database the API is accessing one layer behind that. This construction supplies extra protection in depth in comparison with microservices that may collapse this layered method, which results in extra publicity.

Monolithic API architectures expose fewer IP-addressable distant process calls in comparison with microservice architectures. The result’s that these microservice architectures usually have a bigger assault floor as famous right here. There are additionally many help constructions, just like the service discovery mechanism, wanted to create a safe microservice system that creates extra avenues for potential compromise if they’re tampered with. Microservice architectures are typically extra complicated than monolithic architectures, which will increase the probability of missed checks and misconfigurations that result in vulnerabilities.

Instance. Assume a microservice structure at the moment has 10 API endpoints supported by one API gateway with a transactions per second (TPS) fee restrict of 100 per second. If 10 extra API endpoints are added with the identical TPS fee restrict, meaning the identical variety of purchasers as earlier than can now produce twice as many transactions in the identical period of time among the many APIs. This might result in delays within the API gateway processing the elevated variety of transactions, leading to decreased customer support.

Suggestions. The next suggestions apply to this danger.

  1. Rigorously plan API versioning and deployments. Be strategic about including new APIs so the upkeep and stock of the present APIs don’t turn out to be overwhelming.
  2. Add redundancy measures to forestall overload from API use in help constructions, such because the API gateway and authentication servers.
  3. Keep a radical stock of all APIs, ideally by means of auto-generated documentation for uniformity and searchability.
  4. Configure thorough logging and monitoring efforts for all API exercise, together with logging all authentication and enter failures.

Future Work: API Finest Practices

APIs are more and more widespread, and they’re usually designed and applied in a method that creates safety dangers. This weblog put up, and the report from which it was excerpted, summarized three dangers related to APIs and supplied suggestions about fixing or lowering their influence. A number of the commonest suggestions embody the next:

  • having a regular API documentation course of
  • utilizing automated testing all through the event course of
  • making certain the identification and entry administration system is safe

Future work might lengthen the findings on this report back to (1) discover integrating zero belief measures into the design of APIs and the event course of and (2) create a algorithm and proposals for API greatest practices.
