Petya-like ransomworm: Leveraging InsightVM and Nexpose for visibility into MS17-010
A Petya-like ransomworm struck on June 27th 2017 and spread throughout the day,
affecting organizations in several European countries and the US. It is believed
that the ransomworm may achieve its initial infection via a malicious document
attached to a phishing email, and that it then leverages the EternalBlue

10 Steps Towards the Path of Better Security for Your Business
Information security is hard. So hard, in fact, that many choose to ignore it as
an intractable problem, and choose to ignore it wherever possible. They use the
same password everywhere, carry sensitive data around on unencrypted laptops
which they then leave on public transportation, run old applications on old
operating systems, and a plethora of other such security issues.
In an alarmingly-large number of data breaches, attackers do not resort to
zero-day attacks or secret blackhat hacker te

Petya-like Ransomware Explained
TL;DR summary (7:40 PM EDT June 28): A major ransomware attack started in
Ukraine yesterday and has spread around the world. The ransomware, which was
initially thought to be a modified Petya variant, encrypts files on infected
machines and uses multiple mechanisms to both gain entry to target networks and
to spread laterally. Several research teams are reporting that once victims'
disks are encrypted, they cannot be decrypted

Vulnerability Disclosure
R7-2017-06 | CVE-2017-5241: Biscom SFT XSS (FIXED)
Summary
The Workspaces component of Biscom Secure File Transfer (SFT) version 5.1.1015
is vulnerable to stored cross-site scripting in two fields. An attacker would
need to have the ability to create a Workspace and entice a victim to visit the
malicious page in order to run malicious Javascript in the context of the
victim's browser. Since the victim is necessarily authenticated, this can allow
the attacker to perform actions on the Biscom Secure File Transfer instance on
the victim's behalf.

Legislation to Strengthen IoT Marketplace Transparency
Senator Ed Markey (D-MA) is poised to introduce legislation to develop a
voluntary cybersecurity standards program for the Internet of Things (IoT)
.
The legislation, called the Cyber Shield Act, would enable IoT products that
comply with the standards to display a label indicating a strong level of
security to consumers – like an Energy Star rating for IoT. Rapid7 supports this

Setting Up and Managing a Bug Bounty Program
Synopsis
Bug bounties have become mainstream and rightfully so. They offer a method to
access and harness the intelligence of varied set of expert hackers and security
researchers without having to incur the cost of hiring an army of security
professionals. The main advantage though is that one can keep a step ahead of
the malicious hackers. This article talks about how to setup a bug bounty
program and some of the pitfalls to watch out for.
