CareerBuilder accidentally turns Malware builder
It is bad but kinda funny
Here is the kicker
The actual payload that is dropped on the victim’s computer once the attachment is opened, is likely to slip past defenses, because it is concealed in an image.
From the article:
When a resume is submitted, CareerBuilder automatically sends a notification email to the company that posted the ad, along with the resume attached to it.
In this particular case, when the end-user opens the email and attempts to view the attachment, the document exploits a known vulnerability in Word to place a malicious binary on the user’s system. The binary then contacts a command and control server, which downloads and unzips a image file, which in turn drops a backdoor dubbed Sheldor on the victim’s computer, Proofpoint said in a blog post describing the attack.

You know eBay (who doesn't?) - Do you know that eBay still has a potentially dangerous cross-site scripting (XSS) vulnerability exists even after it was discovered a year back
eBay is not a Mom-n-Pop shop so, how come they are not bothered?
From the Article:
Kääp emailed eBay four times over the course of 12 months – initially a year ago, then again three, five, and seven months after he discovered the bug. After repeated prodding, officials at eBay told Kääp they couldn’t reveal any information about its fix schedule. Each time he emailed, Kääp claims, it was because the vulnerability had not been remedied. While eBay asked him not to disclose his bug, it has neglected to give him a timeline regarding a fix.
the bug could allow an attacker to carry out an XSS attack over eBay’s internal messaging system by catching and tweaking a request.

cloud-based email delivery service hacked - After all they were in email business (not security)
How about this.........
SendGrid, which sells a cloud-based email delivery service, has admitted that the extent of a hack disclosed three weeks ago was much more serious than originally reported.
Campbell said the systems stored SendGrid customer and employee usernames, email addresses, and salted and hashed passwords. Systems holding customer email lists, addresses and contact information were also accessed, Campbell said.
One day after the SendGrid breach, the New York Times reported that attackers used the credentials to breach Bitcoin exchange Coinbase, which confirmed to the Times that hackers had compromised its SendGrid account. Other Bitcoin exchanges were also previously targeted through similar email services, the Times report said.

HTTP/2 - What is it and what is new?
9 Things To Expect
1. Same HTTP APIs
Making HTTP/2 succeed means that it has to work with the existing Web. So, this effort is about getting the HTTP we know on the wire in a better way, not changing what the protocol means.
2. Cheaper Requests
The Web performance community’s mantra is “avoid HTTP requests” because HTTP/1 make them expensive. This has given rise to techniques like inlining, concatenation and spriting to reduce the number of requests on a page.
With HTTP/2, these techniques shouldn’t be necessary
3. Network- and Server-Friendliness
HTTP/2 allows the use of a single connection per host, and encourages sites to consolidate their content on one host where possible.
4. Cache Pushing
HTTP/2’s “server push” allows a server to proactively send things to the client’s cache for future use.
5. Being Able to Change Your Mind
HTTP/2 adds the RST_STREAM frame to allow a client to change its mind; if the browser navigates away from a page, or the user cancels a download, it can avoid having to open a new connection without wasting all of that bandwidth.
6. More Encryption
HTTP/2 doesn’t require you to use TLS (the standard form of SSL, the Web’s encryption layer), but its higher performance makes using encryption easier, since it reduces the impact on how fast your site seems.
7. No More Text
One of the nice things about HTTP/1 is the ability to open up telnet, type in a request (if the server doesn’t time out!) and then look at the response. This won’t be practical in HTTP/2, because it’s a binary protocol. Why?
While binary protocols have lower overhead to parse, as well as a slightly lighter network footprint, the real reason for this big change is that binary protocols are simpler, and therefore less error-prone.
8. It’ll Take Some Time to Get it Right
HTTP/2 isn’t magic Web performance pixie dust; you can’t drop it in and expect your page load times to decrease by 50%.
It’s more accurate to view the new protocol as removing some key impediments to performance; once browsers and servers learn how and when to take advantage of that, performance should start incrementally improving.
9. HTTP/3 and Beyond
HTTP/1.x has lasted for more than fifteen years; why would we be even considering HTTP/3 before HTTP/2 is done?
One of the big reasons that HTTP/2 took so long to get to is that upgrading the protocol in the deployed infrastructure is really hard; there are lots of boxes out there that assume HTTP/1 will never change.
So, if the transition from HTTP/1 to HTTP/2 goes well, it should be a lot easier to introduce the next version, because we can use the same mechanism that we used for the first big hop.

Ever heard of EQUATIONDRUG? - It has nothing to do with Drugs, it is an attack platform to control compromised computers.
We need to install software from a valid install CD but, if that is compromised then how can we protect.
Researchers at Kaspersky Lab have uncovered a cyberespionage group that has been operating for at least 15 years and has worked with and supported the attackers behind Stuxnet, Flame and other highly sophisticated operations.
Once a PC is compromised, the attackers install the EQUATIONDRUG attack platform, which is the main component from which further operations run. The platform includes a variety of modules and has an analog in another platform called GRAYFISH, which is an updated version of the attack framework.
Countries targeted by this group include Russia, Syria, Iran, Pakistan, China, Yemen, Afghanistan, India but also US and UK, between and several others.
GRAYFISH is the most highly evolved version of its attack infrastructure. The attackers began using this platform about seven years ago and have been improving it as they go. - See more at:
The trump card for the Equation Group attackers is their ability to inject an infected machine’s hard drive firmware. This module, known only by a cryptic name – “nls_933w.dll”, essentially allows the attackers to reprogram the HDD or SSD firmware with a custom payload of their own creation.
Fanny creates a hidden storage area on the stick. If it infects a computer without an internet connection, it will collect basic system information and save it into the hidden area of the stick. Later, which a stick containing hidden information is plugged into a computer infected by Fanny having an Internet connection, the data will be scooped from the hidden area and sent to the C&C.
Another incident included an installation CD for Oracle software that included a Trojan dropper for the Equation Group’s malware. This is a tactic that, through the Edward Snowden documents, has been attributed to operations conducted in the past by the National Security Agency.
The C&C infrastructure includes hundreds of domains in a number of countries, including the United States, the UK, Italy and Germany.
“The scariest thing about them is that we don’t have any samples from 2014. So somewhere in 2013 these guys went off the radar,” he said. “We have no idea what they did in 2014, which is very, very scary.” -
