Malvertising campaigns hit US military industry to steal secrets and intellectual property

A new wave of malvertising attacks finalized to cyber espionage is targeting military contractors to military secrets and intellectual property.

Security experts at security company Invincea have uncovered a new malvertisingcampaign used as a attack vector for highly-targeted cyber espionage operations against at least three firms in the US military industry.

The malvertising is becoming even more popular in the criminal underground, many cases were spotted recently which exploited the ad network of IT giants like Googleand Yahoo.

According the experts at Invincea, malvertising campaign allowed threat actors to steal military secrets or intellectual property rather than click-fraud or financial frauds( e.g. Phishing). The circumstance is alarming because many of the targeted companies are providing technology for use in combat zones.

“In the past, we have seen organized cyber crime learn attack techniques from advanced nation state actors,” Invincea Chief Executive Anup Ghosh said, using industry parlance for cyber spies. “This is a case where advanced state actors would be learning from cyber crime in terms of methods and tactics.”

The researchers discovered that using high targeted online advertising threat actors hit major U.S. military contractors in the past few weeks, Invincea declined to name the victims of the malvertising campaigns.

Data security breaches now regularly hit high-profile businesses such asbanks and retailers, leaving millions of consumers vulnerable to identity theft and financial fraud. But research into malvertising has revealed how cyber-criminals and spies can use the marketing industry’s latest tools to pinpoint high-value targets.” reports the Reuters Agency.

The experts at Invincea spotted up to six malvertising attacks that targeted one aerospace contractor and other military contractors in the last weeks of September.

The experts haven’t provided any information on the alleged source of the malvertising attacks, instead they confirmed that attackers used demographic targeting toolsavailable to any online marketer to exploit advertising bidding networks.


“Perpetrators can set up a corporate front to deliver normal ads, then swap landing pages from time to time for malicious code. They place these ads on advertising exchanges and bid up prices for placement on sites that its targets are known to visit, based on what they glean from these intended victims’ advertising profiles.” states the Reuters.

Malvertising website are difficult to be localized, the majority of them belong to the category of One Day Wonders, so the stay online just for the time of the attack, typically for less than four hours. A study conducted by Blue Coat on 660 million unique hostnames reports that 470 Million websites are One Day Wonders and 22 Percent are malicious.

The analysis conducted by experts at Invincea firm confirms the presence of serious flaw in most online advertising networks that could be easily exploited by threat actors.

“Any real-time ad bidding service that allows for automatic redirection is inherently insecure,” said Pat Belcher, who heads Invincea’s security analytics team, which conducted the forensic research. “It is across the board.”

Unfortunately, cyber criminals are winning the fight against the online advertising industry, recent cases demonstrate that the web ad industry is still vulnerable to malvertising campaigns.

Ad networks are too easy to compromise and unaware users haven’t necessary skills and tools to protect their machines.

The major advertising organizations in the US will collaborate to monitor and prevent illegal activities.

“Criminal activity threatens to erode trust in the digital ecosystem,” Randall Rothenberg, chief executive of the Interactive Advertising Bureau said. “It is time that publishers, marketers and agencies stand together to combat these dangerous forces as a unified entity.”

Unfortunately as explained by Invincea malversting is a common practice that is not properly addressed by Advertising industry, it’s time to consider security an indispensable investment and not a cost to reduce.

Hackers Steal Millions In Cash From ATMs, Using Tyupkin Malware

Attackers add in fail safes to prevent innocents from triggering attack and money mules from going rogue.

Attackers are infecting ATMs in Asia, Europe, and Latin America with malware, and walking off with stacks of cash, Kaspersky has found. Using the malware, called Tyupkin, and a team of money mules, the attackers have stolen what amounts to millions of dollars in cash.

“Over the last few years, we have observed a major upswing in ATM attacks using skimming devices and malicious software," said Vicente Diaz, principal security researcher at Kaspersky Lab, in a statement. "Now we are seeing the natural evolution of this threat with cyber-criminals moving up the chain and targeting financial institutions directly. This is done by infecting ATMs themselves or launching direct APT-style attacks against banks. The Tyupkin malware is an example of the attackers taking advantage of weaknesses in the ATM infrastructure.”

The good news is that the infection and theft require physical access to the ATM. The bad news is that it's easy to come by, since ATMs are intended to be physically accessible by the general public 24/7. That said, the attackers only went after machines that did not have security alarms installed.

Once access is gained, the attackers reboot the machine using a bootable CD that installs Tyupkin. The malware then runs in a loop, waiting for a command. It only accepts commands on Sunday and Monday nights, when the mules' suspicious withdrawals are less likely to be noticed.

During those hours, a unique key, based on a random set of numbers displayed by the ATM machine, is generated for each session. Video evidence shows that the mule collecting the cash calls another gang member on the phone and gives them that random combination. The person on the other side of the call then runs those digits through an algorithm to generate the session key, and gives the key to the mule. Once the key is entered, the machine displays the amount of cash located in each cassette, and dispenses 40 banknotes from whichever cassette the attacker chooses.

The process prevents both regular customers from accidentally triggering the attack and money mules from trying to steal the money themselves without the rest of the gang knowing about it.

Google Indonesia was Hacked

As reported today few hours back Google Indonesia was Hacked and left defaced page for hours. The technology gaint Google Indonesia domain which is www.google.co.id was hacked and left defaced for several hours in morning, The very famous Pakistani hackers group “Team Madleets” claimed responsibility for the hack.

Google Indonesia was hijacked using a hacking method known as DNS Spoofing ( DNS Cache Poisoning ) . Pakistani hacker’s group “Team Madleets” are known for such attacks targeting big websites like Google, Last year the same method was used to hijack Google Malasiya domian.

What is DNS Poisoning?
In short, DNS spoofing or DNS cache poisoning is a hacking attack, whereby data is introduced into a Domain Name System (DNS) name server’s cache database, causing the name server to return an incorrect IP address, diverting traffic to another website.

Normally, a networked computer uses a DNS server provided by an Internet service provider (ISP). which are deployed to improve resolution response performance by caching previously obtained query results

Attacker spoofs the IP address DNS entries for a target website on a given DNS server, replacing it with the IP address of a server which he controls, thus redirecting the whole traffic to his deface page. It is believed that the DNS spoofing led the Google Indonesian users to another IP which carried the Madleets defaced page.

Google Indonesia Website was left defaced for several hours
While it is not clear for how long the Google Indonesia website was left defaced, but reports suggest that the attack continued for hours, Team MaDLeeTs also changed the earlier deface page planted after 2 hours with a new one.
