Today I received an email from a business associate whom I often corresponded with. Even though the email looks normal – it contains his full name and the usual email signature – something looks off.
The email body is very terse and contains only a link – alarm bells start going off. The link points to a valid Google docs document.
The document contains 2 links, both pointing to the same external site.
It is seemingly a login page for your Microsoft outlook account. But the domain is not associated with Microsoft. A classic phishing attack.
It so happens that the business associate is using Outlook for his email. After entering his credentials into the phishing site, the attacker must have used his credentials to send a copy of the phishing email to everyone in his contacts. Indeed that is the case, after I have confirmed with other associates. What makes this attack so successful is that 1) the email is from someone you have corresponded with 2) the first link opens a valid Google docs and some would have let their guard down at this point of time.
The latest report from FireEye states that 91% of cyber attacks comes from emails, and email-based attacks are getting increasingly more sophisticated. Some are also taking advantage of how email addresses are being shown on mobile devices.
As cyber threats continue to evolve, we must continue to educate users on the importance of maintaining vigilance and to be mindful of the limitations of current solutions to address the risks of phishing and other attacks.
After the spectacle of Spectre and Meltdown last year, we now have more vulnerabilities that attacks the CPU to leak confidential data. The new vulnerabilities are called RIDL and Fallout – not quite as catchy as Spectre and Meltdown – and it belongs to a class of attacks called MDS (Microarchitectural Data Sampling) attacks.
Our attacks can leak confidential data across arbitrary security boundaries in real-world settings (cloud, browsers, etc.).
Yet another case of unsecured database in the public cloud. That in itself is unfortunately not uncommon. What is eyebrow-raising however, is the type of content that it stores.
The database processed various facial details, such as if a person’s eyes or mouth are open, if they’re wearing sunglasses, or a mask — common during periods of heavy smog — and if a person is smiling or even has a beard.The database also contained a subject’s approximate age as well as an “attractive” score, according to the database fields.
First it was Lenovo and Asus, now Dell has fallen as well. Goes to show that 1) you should uninstall crapware that comes pre-bundled with your Windows machine 2) writing secure software is hard.
What computer do you use? Who made it? Have you ever thought about what came with your computer? When we think of Remote Code Execution (RCE) vulnerabilities in mass, we might think of vulnerabilities in the operating system, but another attack vector to consider is “What third-party software came with my PC?”. In this article, I’ll be looking at a Remote Code Execution vulnerability I found in Dell SupportAssist, software meant to “proactively check the health of your system’s hardware and software” and which is “preinstalled on most of all new Dell devices”.
Wow, the source code of one of the most prolific backdoor tools – CARBANAK – is now available on Github. FireEye has a series of articles dedicated to the analysis of this complex tool, starting with this one.
We kick off CARBANAK Week with the first post in our four-part blog series.
Say what you may about Apple’s infamous app-approval process. But Google Play Store’s permissive approach is what allows such apps to exists.
Security researchers have found a new kind of government malware that was hiding in plain sight within apps on Android’s Play Store. And they appear to have uncovered a case of lawful intercept gone wrong.
This is a common and recurring problem due to lack of awareness and the difficulty of securing data. Think twice before you donate your old devices. At least make an attempt to erase or remove the storage device before doing so.
Use of dedicated software to wipe, especially those from the manufacturer
In the space of six months, one security researcher found thousands of files from dozens of computers, phones and flash drives — most of which contained personal information. All the researcher did was scour the second-hand stores for donated and refurbished tech. New research published by security firm Rapid7 revealed how problematic discarded technology can […]
