Symantec Has Some Flaws With SEP

Comments Off on Symantec Has Some Flaws With SEP

Symantec has warned of three serious vulnerabilities in its Endpoint Protection (SEP) software, and is advising users to update their systems.

The bugs affect all builds of the 12.1 version of the SEP software, with the first two flaws allowing authorised but low privilege users of the software to gain elevated and administrative access to the management console, which can be accessed either locally or through a web-based portal.

The third bug is in the sysplant driver and enables users to bypass the SEP’s security controls and run malware and other malicious code on a targeted client machines.

“Exploitation attempts of this type generally use known methods of trust exploitation requiring enticing a currently authenticated user to access a malicious link or open a malicious document in a context such as a website or in an email,” said the security firm.

There have been no recorded exploits of the flaws, so it would appear that Symantec has squashed the bugs before they became a real-world problem for its customers.

The first two bugs were discovered by security researcher Anatoly Katyushin from rival firm Kaspersky Labs, which is a little embarrassing. Discovery of the third bug was credited to the enSilo Research Team.

Symantec advises SEP users to update their software to the 12.1 RU6 MP4 version. It also recommends that users should take precautions and restrict remote access to the management console in order to prevent hackers from attacking client systems through the web portal.

While hackers can direct sophisticated malware at even the most robustly secured systems, exploiting flaws in software offers an easier route into machines and networks, providing hackers get in before the bugs are discovered and patched.

Recent examples can be seen with the discovery of iOS malware which threatens iPhones through an Apple DRM flaw, and an error on Code.org’s website which saw the emails of its volunteers exposed.

Comments Off on Darkode Hacking Forum Shut Down

Law enforcement agencies from 20 countries collaborated to cripple a major computer hacking forum, and U.S. officials filed criminal charges against a dozen people associated with the website, the U.S. Department of Justice announced.

Darkode.com on is displaying a message saying the site and domain had been seized by the FBI and other law enforcement agencies.

Darkode, a password-protected online forum for criminal hackers, represented one of the gravest threats to the integrity of data on computers across the world, according to David Hickton, U.S. attorney for the Western District of Pennsylvania. “Through this operation, we have dismantled a cyber hornets’ nest of criminal hackers which was believed by many, including the hackers themselves, to be impenetrable.”

Five of the defendants face charges in Hickton’s district.

Darkode allowed hackers and other cybercriminals to sell, trade and share information and tools related to illegal computer hacking, the law enforcement agencies alleged.

Before becoming a member of Darkode, prospective participants were allegedly vetted through a process that included an invitation by a member, the DOJ said in a press release. The prospective member then pitched the skill or products he or she could bring to the forum.

Darkode members allegedly used each other’s skills and products to infect computers and electronic devices of victims around the world with malware, the DOJ said.

The takedown of the forum and the charges announced Wednesday came after the FBI’s infiltration of Darkode’s membership.

Symantec Uncovers Advanced Spying Malware

Comments Off on Symantec Uncovers Advanced Spying Malware

An advanced malicious software application has been discovered that since 2008 was used to spy on private companies, governments, research institutes and individuals in 10 countries, anti virus software maker Symantec Corp said in a report on Sunday.

The Mountain View, California-based maker of Norton anti virus products said its research showed that a “nation state” was likely the developer of the malware called Regin, or Backdoor. Regin, but Symantec did not identify any countries or victims.

Symantec said Regin’s design “makes it highly suited for persistent, long-term surveillance operations against targets,” and was withdrawn in 2011 but resurfaced from 2013 onward.

The malware uses several “stealth” features “and even when its presence is detected, it is very difficult to ascertain what it is doing,” according to Symantec. It said “many components of Regin remain undiscovered and additional functionality and versions may exist.”

Almost half of all infections occurred at addresses of Internet service providers, the report said. It said the targets were customers of the companies rather than the companies themselves. About 28 percent of targets were in telecoms while other victims were in the energy, airline, hospitality and research sectors, Symantec said.

Symantec described the malware as having five stages, each “hidden and encrypted, with the exception of the first stage.” It said “each individual stage provides little information on the complete package. Only by acquiring all five stages is it possible to analyze and understand the threat.”

Regin also uses what is called a modular approach that allows it to load custom features tailored to targets, the same method applied in other malware, such as Flamer and Weevil (The Mask), the anti virus company said. Some of its features were also similar to Duqu malware, uncovered in September 2011 and related to a computer worm called Stuxnet, discovered the previous year.

Symantec said Russia and Saudi Arabia accounted for about half of the confirmed infections of the Regin malware and the other countries were Mexico, Ireland, India, Iran,Afghanistan, Belgium, Austria and Pakistan.

Comments Off on Hackers Infiltrate Jimmy Johns

Sandwich restaurant chain Jimmy John’s said there was a potential data breach involving customers’ credit and debit card information at 216 of its stores and franchised locations on July 30.

An intruder stole log-in credentials from the company’s vendor and used the credentials to remotely access the point-of-sale systems at some corporate and franchised locations between June 16 and Sept. 5, the company said.

The chain is the latest victim in a series of security breaches among retailers such as Target Corp, Michaels Stores Inc and Neiman Marcus.

Home Depot Inc  said last week some 56 million payment cards were likely compromised in a cyberattack at its stores, suggesting the hacking attack at the home improvement chain was larger than the breach at Target Corp.

More than 12 of the affected Jimmy John’s stores are in Chicago area, according to a list disclosed by the company.

The breach has been contained and customers can use their cards at its stores, the privately held company said.

Jimmy John’s said it has hired forensic experts to assist with its investigation.

“Cards impacted by this event appear to be those swiped at the stores, and did not include those cards entered manually or online,” Jimmy John’s said.

The Champaign, Illinois-based company said stolen information may include the card number and in some cases the cardholder’s name, verification code, and/or the card’s expiration date.

Cryptolocker Infects 250K Systems

Comments Off on Cryptolocker Infects 250K Systems

DELL’s security research team has revealed that a new form of ransomware, dubbed “Cryptolocker” has managed to infect up to 250,000 devices, stealing almost a million dollars in Bitcoins.

“Based on the presented evidence, researchers estimate that 200,000 to 250,000 systems were infected globally in the first 100 days of the CryptoLocker threat,” Dell announced in a Secureworks post.

The firm worked out that if the Cryptolocker ransomware threat actors had sold its 1,216 total Bitcoins (BTC) that they collected from September this year, immediately upon receiving them, they would have earned nearly $380,000.

“If they elected to hold these ransoms, they would be worth nearly $980,000 as of this publication based on the current weighted price of $804/BTC,” Dell said.

Cryptolocker is unique when compared against your average ransomware. Instead of using a custom cryptographic implementation like many other malware families, Cryptolocker uses third-party certified cryptography offered by Microsoft’s CryptoAPI.

“By using a sound implementation and following best practices, the malware authors have created a robust program that is difficult to circumvent,” Dell said.

Conventionally, ransomware prevents victims from using their computers normally and uses social engineering to convince them that failing to follow the malware authors’ instructions will lead to real-world consequences. These consequences, such as owing a fine or facing arrest and prosecution, are presented as being the result of a fabricated indiscretion such as pirating music or downloading illegal pornography.

“Victims of traditional forms of ransomware could ignore the demands and use security software to unlock the system and remove the offending malware,” Dell explained. “Cryptolocker changes this dynamic by aggressively encrypting files on the victim’s system and returning control of the files to the victim only after the ransom is paid.”

Dell said that the earliest samples of Cryptolocker appear to have been released on 5 September this year. However, details about its initial distribution phase are unclear.

“It appears the samples were downloaded from a compromised website located in the United States, either by a version of Cryptolocker that has not been analysed as of this publication, or by a custom downloader created by the same authors,” Dell added.

Dell seems to think that early versions of Cryptolocker were distributed through spam emails targeting business professionals as opposed to home internet users, with the lure often being a ‘consumer complaint’ against the email recipient or their organisation.

Attached to these emails would be a ZIP archive with a random alphabetical filename containing 13 to 17 characters, containing a single executable with the same filename as the ZIP archive but with an EXE extension, so keep your eye out for emails that fit this description.

Phishing Attacks Increasing

Comments Off on Phishing Attacks Increasing

Security researchers at Kaspersky Lab have reported significant growth in phishing attacks over the last year.

In a study entitled “The Evolution of Phishing Attacks”, Kaspersky said it found 37.3 million out of its 50 million customers running its security products that were at risk of being phished from 2012 to the present, an 87 percent increase over the same period between 2011 and 2012.

“The nature of phishing attacks is such that the simplest types can be launched without any major infrastructure investments or in-depth technological research,” Kaspersky said in the report.

“This situation has led to its own form of ‘commercialization’ of these types of attacks, and phishing is now being almost industrialized, both by cybercriminals with professional technological skills and IT dilettantes.”

The security firm explained that overall, the effectiveness of phishing, combined with its profitability for criminals and how simple the process is to undertake has led to a steadily rising number of these types of incidents.

Kaspersky noted that most of the victims in 2012-2013 were located in just ten countries, that is, Russia, the US, India, Germany, Vietnam, the UK, France, Italy, China and Ukraine. These 10 countries were home to 64 percent of all phishing attack victims during this time.

In addition to a rise in the number of users attacked, the number of servers involved in phishing attacks also increased, Kaspersky said, without giving any exact numbers. Though the firm did reveal that internet giants like Yahoo, Google, Facebook and Amazon are the top targets of malicious users.

“Online game services, online payment systems, and the websites of banks and other credit and financial organizations are also common targets,” the firm added, warning users to stay vigilant when entering personal data.

Comments Off on Microsoft Seizes Botnet Servers

Microsoft Corp scored a win in efforts to fight online banking fraud, saying it had seized several servers used to steal login names and passwords, disrupting some of the world’s most sophisticated cybercrime rings.

The software giant said on Monday that its cybercrime investigation group also took legal and technical actions to fight notorious criminals who infect computers with a prevalent malicious software known as Zeus.

By recruiting computers into networks called botnets, Zeus logs the online activity of infected machines, providing criminals with credentials to access financial accounts.

“We’ve disrupted a critical source of money-making for digital fraudsters and cyber thieves, while gaining important information to help identify those responsible and better protect victims,” said Richard Boscovich, senior attorney for the Microsoft Digital Crimes Unit, which handled the investigation in collaboration with the financial industry.

Microsoft’s Digital Crimes Unit is worldwide team of investigators, lawyers, analysts and other specialists who fight cybercrime. A year ago they helped U.S. authorities take down a botnet known as Rustock that had been one of the biggest producers of spam e-mail. Some security experts estimated that in its heyday Rustock was responsible for half the spam in junk email bins.

Yahoo Messenger Flaw Exposed

Comments Off on Yahoo Messenger Flaw Exposed

An unpatched Yahoo Messenger vulnerability that allows hackers to change people’s status messages and possibly perform other unauthorized functons can be exploited to spam malicious links to a large number of users.

The flaw was discovered in the wild by security researchers from antivirus vendor BitDefender while investigating a customer’s report about unusual Yahoo Messenger behavior.

The flaw appears to be located in the application’s file transfer API (application programming interface) and allows attackers to send malformed requests that result in the execution of commands without any interaction from victims.

“An attacker can write a script in less than 50 lines of code to malform the message sent via the YIM protocol to the attacker,” said Bogdan Botezatu, an e-threats analysis & communication specialist at BitDefender.

“Status changing appears to be only one of the things the attacker can abuse. We’re currently investigating what other things they may achieve,” he added.

Victims are unlikely to realize that their status messages have changed and if they use version 11.5 of Yahoo Messenger, which supports tabbed conversations, they might not even spot the rogue requests, Botezatu said.

This vulnerability can be leveraged by attackers to earn money through affiliate marketing schemes by driving traffic to certain websites or to spam malicious links that point to drive-by download pages.

Comments Off on Cell Phones Can Be Dangerous

It appears that an Australian brain surgeon has called the latest report in reference to the report on the potential harmful effects of mobile phones as a wake-up call to users and the telecommunications industry.

Dr Teo, said he was “pleased” that at last there came conclusive proof that mobile phones caused brain tumours. He also went on to say that the report should serve as a ”wake up call’ that should alert both the public and the mobile phone industry to the link between mobile use and cancer.”

As you know a report was released by the World Health Organisation’s cancer research wing that said radio frequency electromagnetic fields generated by cell phones are “possibly carcinogenic to humans” and heavy usage could lead to a possible increased risk of glioma, a malignant type of brain cancer.
