Rusko a Čína nahánějí strach. NATO musí pracovat na kybernetické obraně, vyzval Carter

Novinky.cz - bezpečnost - 25 Červen, 2015 - 09:28
Severoatlantická aliance by měla zlepšit svou obranu proti potenciálním hackerským útokům z cizích zemí dříve, než vybuduje své vlastní útočné kybernetické prostředky. Prohlásil to ve středu americký ministr obrany Ashton Carter při jednání se svými resortními kolegy z členských zemí NATO v Bruselu. Jeho výzva je podle agentury AP v protikladu k názoru řady expertů či politiků, podle nichž by Aliance měla vyvíjet kybernetické zbraně, aby zastrašila své soky.

Not OK, Google: Chromium voice extension pulled after spying concerns

Ars Technica - 25 Červen, 2015 - 00:37

Google has removed an extension from Chromium, the open source sibling to the Chrome browser, after accusations that the extension was installed surreptitiously and subsequently eavesdropped on Chromium users.

The issue first came to light in late May when a bug was filed in the Debian bug tracker. Chromium version 43 was seen downloading a binary extension from Google, and there was neither any ability to prevent this download, nor any source code available for the extension. The extension, called "Chrome Hotword," was found to be responsible for providing the browser's "OK, Google" functionality. Although off by default, both Chrome and Chromium, when set to use Google as their default search engine, can permanently listen to the microphone and respond instantly to voice queries, with "OK Google" used as the trigger keyword.

Concern about the nature and purpose of the extension was compounded by the way the browser did and didn't disclose the extension's existence. The list of extensions visible at chrome://extensions/ doesn't include Hotword. Conversely, Hotword's own status page, chrome://voicesearch/ said that by default the extension was enabled and had access to the microphone.

OPM director on security issues: We’re trying very hard

Ars Technica - 24 Červen, 2015 - 23:48

With the total number of people affected by the data breach at the Office of Personnel Management now estimated to be as many as 18 million, OPM Director Katherine Archuleta has mounted a public relations counter-attack, defending the agency's efforts to improve security during her tenure and crediting those efforts with finding the malware at the heart of the breach in the first place. But the news of the exposure has caused a wave of fear and distrust among federal employees—with some who work in the intelligence community now concerned for their families' safety.

Archuleta defended her tenure before a Senate hearing on June 23. "I'm as angry as you are that this is happening," she said in a message to federal employees and retirees during her testimony. "I am dedicated to ensuring that OPM does everything in its power to protect the federal workforce, and to ensure that our systems will have the best cyber security posture the government can provide.” And she insisted that no one at OPM was to blame for the breaches, saying, "If there is anyone to blame, it is the perpetrators."

Archuleta also acknowledged for the first time that the breach was at least partially related to the breach last year of an OPM investigative contractor, KeyPoint. Attackers used credentials stolen from a KeyPoint employee to access OPM's network initially, gaining access to the EPIC background investigation software tools.

Hershey Park Investigates Card Fraud Pattern

Krebs on Security - 24 Červen, 2015 - 19:45

Hershey Park, a popular resort and amusement park in Hershey, Pa. has hired a security firm to investigate reports from multiple financial institutions about a possible credit card breach, KrebsOnSecurity has learned.

Contacted after reports by several financial institutions about a pattern of fraudulent charges on customer cards that trace back to Hershey properties, the company says it is investigating.

“We have received reports from some of our guests that fraud charges appeared on their payment cards after they visited our property,” said Kathleen McGraw, director of communications for Hershey Entertainment and Resorts Company.

“We take reports like this very seriously,” McGraw continued. “While our company does have security measures in place designed to prevent unauthorized access to our network, we immediately began to investigate our system for signs of an issue and engaged an external computer security firm to assist us. The investigation is ongoing.”

Sources at three financial institutions say they have detected a pattern of fraudulent activity on customer cards that were used at Hershey properties in Pennsylvania between mid-March and late May 2015. According to the banks, the cards were used at a variety of Hershey locations, including food and beverage outlets, ticketing stations and the Hershey Lodge.

Patch early, patch often: Adobe pushes emergency fix for active 0-day

Ars Technica - 24 Červen, 2015 - 19:13

Yet again, Adobe has released a new patch to fix a critical vulnerability that "could potentially allow an attacker to take control of the affected system," according to the company.

Adobe acknowledged that the flaw (CVE-2015-3113) is "being actively exploited in the wild via limited, targeted attacks." Known affected systems run Internet Explorer for Windows 7 and below and Firefox on Windows XP, according to the patch details. Adobe says the following software can potentially be impacted:

  • Adobe Flash Player and earlier versions for Windows and Macintosh
  • Adobe Flash Player Extended Support Release version and earlier 13.x versions for Windows and Macintosh
  • Adobe Flash Player and earlier 11.x versions for Linux

The company recommends updating to the latest version of Flash to avoid the risk of exploitation, but at this point users should take a hard look at how necessary Flash is to their daily Internet use. In 2015 alone, we've seen Adobe issue multiple emergency Flash updates to patch critical vulnerabilities under active attack—including three such instances in the first five weeks of the year. The situation has gotten so grim that security reporter Brian Krebs recently experimented with a month without having the Flash Player installed at all. "The result? I hardly missed it at all," Krebs writes.

This newest flaw was uncovered through the help of FireEye security researchers. A Singapore-based FireEye team discovered the vulnerability in June by detecting a phishing campaign exploiting CVE-2015-3113. "The attackers’ e-mails included links to compromised Web servers that served either benign content or a malicious Adobe Flash Player file that exploits CVE-2015-3113," FireEye writes.

FireEye identified APT3, a China-based group also known as UPS, as responsible for these attacks (see more on the group in FireEye's report on Operation Clandestine Fox). APT3 has previously introduced other browser-based zero-day attacks against Internet Explorer and Firefox. FireEye notes APT3's tactics are difficult to monitor given there's little overlap between campaigns, and the group typically moves quickly ("After successfully exploiting a target host, this group will quickly dump credentials, move laterally to additional hosts, and install custom backdoors," the new report states). According to the security researchers, APT3 has implemented these phishing schemes against companies in aerospace and defense, engineering, telecommunications, and transportation this year.

FireEye's report on CVE-2015-3113 offers much greater detail than Adobe's patch notes. For instance, the typical phishing e-mails were spam-like offers for refurbished iMacs:

"Save between $200-450 by purchasing an Apple Certified Refurbished iMac through this link. Refurbished iMacs come with the same 1-year extendable warranty as new iMacs. Supplies are limited, but update frequently.

Don't hesitate . . .>Go to Sale"

FireEye also broke down where unfortunate targets were directed after clicking such URLs—a compromised server hosting JavaScript profiling scripts. "Once a target host was profiled, victims downloaded a malicious Adobe Flash Player SWF file and an FLV file," FireEye reports. "This ultimately resulted in a custom backdoor known as SHOTPUT, detected by FireEye as Backdoor.APT.CookieCutter, being delivered to the victim’s system. The payload is obscured using xor encoding and appended to a valid GIF file."

False positive: National Archives files matched OPM signature, but were legit [Updated]

Ars Technica - 24 Červen, 2015 - 17:24

Update: National Archives officials now report that the "indicators of compromise" found on three Archives systems were a false positive, and that no breach has occurred, contrary to a NextGov report yesterday. Laura Diachenko, a spokesperson for the National Archives, told Ars in an e-mail that there had been files that matched a fingerprint for the malware  had been detected on the Archives' network.

"The National Archives (NARA) detected two files on three individual workstations that matched some of the criteria that the Department of Homeland Security provided, in the wake of the Office of Personnel Management hack," Diachenko told Ars. "We took precaution by immediately reporting to US-CERT. US-CERT has deemed the files found on NARA's computers to be legitimate files and not associated with the OPM incident. NARA is partnering with DHS and US-CERT pro-actively to ensure that NARA systems are protected to the fullest extent possible."

The "indicators of compromise", or IOCs, shared by the Department of Homeland Security, had been fed into the National Archives' in-house vulnerability scanning tool. They triggered an alert. However, contrary to NextGov's report, those files were in fact found to be benign, and related to Internet Explorer.
