Infosec quotes - antivirus alerts do not mean problem solved

Realize Antivirus alerts don't mean the problem solved. The Antivirus usually just detects a single remnant linked to a bigger problem.

@jepayneMSFT says “... WMI persistence often needs a post detection remediation step ... like rebuilding the WMI database. For attackers this is a great advantage, especially in less informed IT organizations who might think an AV pop up means 'problem solved.'..”

“...We often see companies embark on Least Privilege or Whitelisting projects but leave more complex users (IT, C-levels, mobile workers, developers) out of the project scope because it's too 'hard'... Remove admin rights, remove threats...”

This applies to more than just Petya!

“... if the user does not have admin rights, infection will not spread beyond the infected device. ... if has admin rights, it will spread laterally ...”

- Greg Kilcommons

Infosec quotes - SIEM rules

Just because you have 200 use cases turned on in your SIEM solution, does not mean they are actually configured to detect useful and actionable events.

Just because you have metrics of the number of use case events per day, doesn't mean those metrics are additionally useful.

If you don't have quality data and a quality plan, you don't have quality security.  #focusonthefundamentals

- Brandon Rizzo

Infosec quotes - remove admin rights

Overall, we learned the number of reported Microsoft vulnerabilities increased by 111% between 2013 and 2017. The biggest takeaway, these can all be mitigated with the removal of administrative rights.

Infosec quotes - log source monitoring

Good example of why it's smart to have a process in place to check your SIEM for critical log sources that have stopped sending logs. If your main firewall stops sending logs, somebody should notice.

“... a firewall did not come back online after the third-party server provider run a routine maintenance operation...The Bee’s database was exposed to the public internet for about two weeks...”

“... 5 Things a System Administrator Should Never Do... # 5 Checking your email or surfing the web using your admin account...”

probably linked to weblogic vuln

Infosec quotes - chrome extension logging

Browser extensions are scarey because they can control any website you visit.

“... Chrome extensions have started embedding Yandex Metrica, which records user actions on all the sites they surf ... the script can log various details such as names, credit card numbers, CVV numbers, email addresses, and phone numbers...”


Thursday, February 1, 2018

Infosec quotes - microsegmentation is good

With breaches becoming commonplace Microsegmentation is one of the best ways to reduce risk by making it harder for attackers to move laterally.

“... Microsegmentation gives companies greater control over the growing amount of east-west or lateral communication that occurs between servers, bypassing perimeter-focused security tools. If breaches occur, microsegmentation limits potential lateral exploration of networks by hackers...”

Infosec quotes - firefox add-ons

Good reason to lock down firefox add-one at your company just like you whitelist your Desktop software.

“... A family of malicious Firefox addons have been discovered being pushed by sites pretending to be a manual update for Firefox...”


Infosec quotes - no downtime no patch

A sad but common reality. Eventually orgs will have to adapt and find ways to lower risks while still becoming quicker and more agile.

“... Oracle issued updates for this issue earlier this month, but it will take months until the patch lands on affected POS systems. The reason is that POS systems are business critical systems, and sysadmins rarely schedule maintenance and update operations, fearing that an unstable patch might cause further downtime and financial losses to their companies...”

Infosec quotes - Siemens vulns

Does your company have a process in place to watch for and apply regular patches from vendors of non traditional systems like these ?

“... Vulnerability could be exploited by an attacker to bypass the authentication mechanism ... Vulnerability could be exploited by an authenticated attacker with a low-privileged account to escalate privileges and perform administrative operations ... Vulnerability could be exploited by an attacker to cause a DoS ...”

Infosec quotes - dns hijacking

“...There's a simple way to mitigate the threat of DNS hijacking attacks: don't allow arbitrary internal IP addresses on your enterprise network to send DNS queries to arbitrary IP addresses on the Internet...only a subset of your DNS servers actually query DNS servers on the Internet...”

Infosec quotes - keygen RAT

A good example of why keygens and license crackers aren't just an ethical dilemma for a company , they are straight up a Security risk. 

“...Hacker RAT Malware found in key generator for Burpsuite ...”

Infosec quotes - Wordpress plug-ins

If you don't include Wordpress plugins in your patching cycle it will eventually lead to your site getting hacked.

“... Breaking into an unpatched WordPress installation in under two minutes...”

Infosec quotes - internal password re-use

I think password re-use risks also apply to internal devices at companies too. If you set multiple servers, databases, devices , service accounts, etc to different accounts but the same password then you're simplifying the attackers life by making it trivial for them to laterally move across your network. Take that extra step and create unique passwords.

“... once fraudsters have managed to guess one password, they’ll have access to your entire online life...”


Infosec quotes - upgrade Powershell

Why upgrade Powershell? If nothing else just so your security team can see attacks happening !

“... PowerShell 2.0 ... provides very little evidence of attacker activity ... Microsoft has been taking steps to improve the security transparency of PowerShell in recent versions. The most significant improvements, such as enhanced logging, were released in PowerShell version 5.0 ...”


Infosec quotes - Powershell unrestricted

“... The lowest Execution Policy is Unrestricted, which permits all scripts to run ... If you do choose the Unrestricted setting, and a script comes along and clobbers you ... be prepared to own up to your decision when you're explaining how a virus wiped out your environment...”


Infosec quotes - password vs encryption

Hard drive encryption is important. Don't  disable it. A password does not protect a hard drive that an attacker has physically stole. If he physically holds an unencrypted hard drive he can access its contents.

@gattaca said ““All the stolen $company laptops were password-protected, although not all were encrypted.” < *facepalm*”


Infosec quotes - flash with active exploits

Patch your Flash player. Even if you don't normally rush to patch, this is a good example where you would want to rush and patch. Critical vuln being actively exploited.

“... allow an attacker to take control of the affected system. Adobe is aware of a report that an exploit for CVE-2018-4878 exists in the wild ... attacks leverage Office documents with embedded malicious Flash content distributed via email...”


Infosec quotes - adaptive phishing

#phishing pages that change the look & feel based on your email address!

“... It grabs the favicon from the email address domain and re-uses it on the fake webpage. This is a simple but cool way to make the webpage more attractive....”
