Cybercriminals continue actively abusing/mixing legitimate and purely malicious infrastructure, on their way to take advantage of clean IP reputation, for the purpose of achieving a positive ROI (return on investment) out of their fraudulent/malicious activities, in terms of attribution and increasing the average lifetime for their campaigns. Acting as intermediaries within the exploitation/social engineering/malware-serving chain, the market segment for this type of cybercrime-friendly services continues flourishing, with more vendors joining it, aiming to differentiate their UVP (unique value proposition) through a variety of ‘value-added’ services. We’ve recently spotted yet another managed/on demand redirector generating service, that’s empowering potential cybercriminals with the […]

Cybercriminals continue to populate their botnets, with new infected hosts, through the persistent and systematic spamvertising of tens of thousands of fake emails which impersonate popular and well known brands – all in an attempt to socially engineer prospective victims into interacting with the scam. We’ve recently intercepted a currently circulating malicious spam campaign, impersonating Evernote, serving client-side exploits to prospective victims who click on the links found in the fake emails.

Happy New Year, everyone! Despite the lack of blog updates over the Holidays, we continued to intercept malicious campaigns over the same period of time, proving that the bad guys never take holidays.

More details:
It’s that time of the year! The moment when we reflect back on the cybercrime tactics, techniques and procedures (TTPs) that shaped 2013, in order to constructively speculate on what’s to come for 2014 in terms of fraudulent and malicious campaigns, orchestrated by opportunistic cybercriminal adversaries across the globe. Throughout 2013, we continued to observe and profile TTPs, which were crucial for the success, profitability and growth of the cybercrime ecosystem internationally, such as, for instance, widespread proliferation of the campaigns, professionalism and the implementation of basic business/economic/marketing concepts, improved QA (Quality Assurance), vertical integration in an attempt to occupy […]
WhatsApp users, watch what you click on! A currently circulating fraudulent spam campaign is brand-jacking WhatsApp in an attempt to trick its users into clicking on links found in the email. Once socially engineered users fall victim to the scam, they’re automatically exposed to a fraudulent pharmaceutical site, offering them pseudo bargain deals.

Over the last two months, we’ve been closely monitoring — and proactively protecting from — the malicious campaigns launched by cybercriminals who are no strangers to the concept of social engineering topic rotation. Their purpose is to extend a campaign’s life cycle, or to generally increase a botnet’s infected population by spamming out tens of thousands of fake emails, exposing users to malicious software. The most recent campaign launched by the same cybercriminal(s), is once again impersonating T-Mobile U.K in an attempt to trick mobile users into thinking that they’ve received a legitimate MMS Gallery notification. In reality though, once the […]
