www.itproportal.com/news/email-attacks-are-on-the-rise/ The number of organisations that use email security as part of their threat defences is actually shrinking, new figures from Cisco are showing. The Cisco 2019 Cybersecurity Series says that this year, 41 per cent of organisations have this type of security set up, down from 56 per cent last year. At the same time, the number of email threats is on the rise, and email as a threat in general is considered one of the top issues keeping CISOs up at night.

Ars Technica: Millions of machines affected by command execution flaw in Exim mail server

arstechnica.com/information-technology/2019/06/millions-of-machines-affected-by-command-execution-flaw-in-exim-mail-server/ Millions of Internet-connected machines running the open source Exim mail server may be vulnerable to a newly disclosed vulnerability that, in some cases, allows unauthenticated attackers to execute commands with all-powerful root privileges.. The flaw, which dates back to version 4.87 released in April 2016, is trivially exploitable by local users with a low-privileged account on a vulnerable system running with default settings. All that’s required is for the person to send an email to “${run{…}}@localhost,” where “localhost” is an existing local domain on a vulnerable Exim installation. With that, attackers can execute commands of their choice that run with root privileges.. The command execution flaw is also exploitable remotely, albeit with some restrictions

How spammers use Google services

www.kaspersky.com/blog/spam-through-google-services/27228/ As you know, Google is not just a search tool, but multiple services used by billions of people every day: Gmail, Calendar, Google Drive, Google Photos, Google Translate, the list goes on.

The downside is that online fraudsters have learned to exploit the convenience of Google services to send spam or worse.

Zero Trust: Debunking Misperceptions

blog.paloaltonetworks.com/2019/06/network-zero-trust-debunking-misperceptions/ As organizations explore Zero Trust as a means to prevent successful cyberattacks, more vendors are using Zero Trust as a cybersecurity buzzword. If you walked through the halls of RSA this year, you will have noticed this to be true. Zero Trust was a part of dozens upon dozens of vendor booths, presentations, pamphlets, etc. in one fashion or another. This has resulted in misperceptions of what Zero Trust really is. With the recent availability of Zero Trust products, the perception is that Zero Trust is all about identity or the belief that you have to rip and replace everything to achieve it. With so much noise and confusion, its no surprise that people believe that its a complex, costly and time-consuming initiative.

Interesting JavaScript Obfuscation Example

isc.sans.edu/forums/diary/Interesting+JavaScript+Obfuscation+Example/25020/ Last Friday, one of our reader (thanks Mickael!) reported to us a phishing campaign based on a simple HTML page. He asked us how to properly extract the malicious code within the page. I did an analysis of the file and it looked interesting for a diary because a nice obfuscation technique was used in a Javascript file but also because the attacker tried to prevent automatic analysis by adding some boring code. In fact, the HTML page contains a malicious Word d

www.bleepingcomputer.com/news/security/fbi-issues-warning-on-secure-websites-used-for-phishing/ The U.S. Federal Bureau of Investigation (FBI) issued a public service announcement regarding TLS-secured websites being actively used by malicious actors in phishing campaigns.

Users also look for after landing on a website is the “https” protocol designation in front of the hostname which is another hint of a domain being “secure” and the web traffic is encrypted.
