Check your Exchange for ongoing leaks

Currently the biggest exposure to threats in the cyber domain is presented via mail. Phishing attacks tricks out the credentials for legitimate users and then gain access to the mail account, and some actors will sit with this access to months looking for ways to benefit from this access. As a way of establishing persistence an attacker will often create rules in the mail-system to have mail forwarded to an external account the attacker controls. This way, even if you change passwords, the attacker still receives copies of the mail.

These forwarding rules can serve as valuable indicators. And even if absence of evidence is not evidence of absence, it is worth to look for these rules with regular intervals. This is nothing new, but a reminder seemed in place given the current threat landscape. Here is an older blogpost from Compass-Security explaining the issue.

There is also a project on Github to help faciliate testing and low-volume activity data acquisition from the Office 365 Management Activity API that might be interesting in this regard.

RedCurl cybercrime group discovered

This blog post is a summary of this week’s Information Security News put together by our Security Incident Response Team (SIRT)

A new CyberCrime group nicknamed RedCurl has been discovered after over two years of operation, attacking at least 14 organizations in over 26 attacks. They are known to attack companies in at least six countries, including Norway with banks, insurance and financial companies as some of the industries that they went after. The group was discovered by Group-IB, a global threat hunting and intelligence company headquartered in Singapore, and released a 57 page report on it.

The groups modus operandi did not use advanced tools but rather relied on handcrafted phishing emails, powershell and time to successfully carry out their attacks.

According to the Group-BI report “The attackers posed as members of the HR team at the targeted organization and sent out emails to multiple employees at once, which made the employees less vigilant, especially considering that many of them worked in the same department“, and used the companies logos, signature lines, and spoofing the companies own domain making it very difficult to spot that the mails were not legitimate.

Zoom continues to face security issues

This blog post is a summary of this week’s Information Security News put together by our Security Incident Response Team (SIRT)

Zoom has become very popular as people are working from home and unable to travel, but faced backlash after multiple security vulnerabilities was discovered earlier this year. Now Cisco Talos discovered two more security vulnerabilities that could lead to remote code execution. One of the bugs was in zooms giphy animated gif code that could lead to path traversal and arbitrary file write, and the other one was in Zooms message processing code where a specially crafted message could lead to arbitrary code execution. Both vulnerabilities was disclosed to Zoom and a patch was released
before Talos publicly released the information. Just another reminder to keep software up to date.

Zoom also announced that they will no longer offer end-to-end encryption to its free user but offer it as part of its premium feature for paid customers. The move has been criticized by security experts, especially in lieu of all the recent security vulnerabilities discovered in their platform. Eric Yuan, Zooms CEO claim that the move is to work together with FBI and local law enforcement in case someone use Zoom for a bad purpose

According to Google’s project zero there are vulnerabilities in Apples operating systems media managements. The vulnerabilities could let an attacker gain access by sending a specially crafted image or video to a target and no interaction would be needed from the user to be exploited.
The vulnerabilities was found using fuzzing techniques on previously found bugs, and the vulnerabilities they found have now been fixed.

Reality Check: The Story of Cybersecurity

This blog post is a summary of this week’s Information Security News put together by our Security Incident Response Team (SIRT).

“Often, hackers are portrayed as “technical sorcerers” while defenders are “hapless techies focused on zero-day vulnerabilities and only the most advanced threat vectors,” but in reality, that’s not true.
Cybercriminals are not always sophisticated, and in fact, more script kiddies exist than technically savvy hackers.
The difference is that cybercriminals are more organized and create tools and exploit kits that allow less sophisticated actors to become well equipped in launching attacks.”

said Rohit Ghai, president of RSA, in his keynote at the RSA Conference in San Francisco this week.

“The security landscape needs to change the narrative of its story. So we need to reclaim our narrative, reorganize our defense, and rethink our culture.”
this was his solicitation to the cyber security community.
