While millions of mobile users are anticipating the launch of the new iPhone (5S and 5C), cybercriminals are already making their move to distribute spam that promise to give away the said devices for free, in the guise of a contest. We saw samples of spammed messages that attempted to spoof an Apple Store email notification. The said message informs recipients that they won the latest iPhone 5S mobile phones and iPad. Figure 1. Fake Apple email To get these prizes, they are asked to go to afalse

Researchers have spotted the first in-the-wild apps to exploit a critical Android vulnerability allowing attackers to inject malicious code into legitimate programs without invalidating their digital signature. The two apps, distributed on unofficial Android marketplaces in China, help people find doctors and make appointments, according to a blog post published Tuesday by researchers from security firm Symantec. By exploiting the recently disclosed "master key" vulnerability—or possibly a false

Everyday there is a new threat with seemingly innocent emails being sent out that look close to an official correspondence from a company, from Paypal, ADP and BBB - to name a few. Cybercriminals are mimicking the online payment processor PayPal in a malicious spam campaign that attempts to dupe customers into downloading malware from links in seemingly authentic emails, according to a Webroot report written by Dancho Danchev. The piece of malware in use here is a backdoor that, oncefalse

According to the article in Dark Reading, Study: Phishing Messages Elude Filters, Frequently Hit Untrained Users, many people are still being tripped up by phishing emails. The article summarizes the findings of a survey that was conducted at the Black Hat USA security conference held in July 2012. Of the 250 conference attendees that were polled, 69% said that phishing messages get past spam filters and into users’ inboxes on a weekly basis. Over 25% indicated that top executives and otherfalse

Beware any emails which claim to come from privacy@microsoft.com - it could be that you're being targeted in an attack designed to steal your AOL, Gmail, Yahoo or Windows Live password. At first glance, if you don't look too carefully, the emails entitled "Microsoft Windows Update" may appear harmless enough. But the grammatical errors and occasional odd language should raise alarms bells that the emails may not really be from Microsoft. Dear Windows User, It has come to our attention thatfalse

Cybercriminals have spammed out malware, attached to emails claiming to be related to discounts for offers on Groupon. The emails, which have the poorly spelt subject line of "Groupon discount gifts" (in itself something which should ring alarm bells), pretend to come from Groupon, and claim that one of your friends has found a deal on the website. The website says that your friend has decided to share the deal with you, and that you are receiving a discount code as a result. Part of the emailfalse

For those on our Security Alert and Update list we just emailed an article by Graham Cluley on how a malware attack spread as email from your office's HP scanner, yes that's right a scanner! In these high-tech times, scanners and photocopiers aren't just dumb machines sitting in the corner of the office. They are usually connected to the corporate network, and - in some cases - can even email you at your desk to save you having to wear out your shoe leather. And it's precisely thisfalse

Cybercriminals are attempting to infect the computers of internet users, via a spammed-out email that has a malware-infected file attached. Computer users are being warned to be wary of email messages which suggest they contain nude photographs of girlfriends, or claim that they have been reported to the police, as the attached file (Photo.zip) really contains a Trojan horse. There are many different subject lines being used in the malware campaign, including:

The headline reads, “FBI warns of new malware targeting bank accounts," but it could just as well say, “More new victims born from opening emails.” From the simple act of opening an email and clicking on an attachment, the victim's username and password to their bank accounts are stolen by a process called keylogging, where the info is presto, logged directly from your very fingers as you type in your credentials. What's scary is that bogus emails can appear to come from someone you know is afalse
