[...] The plaintiffs amended their complaint after Yahoo last October revealed that the 2013 breach affected all 3 billion users, tripling its earlier estimate. Koh said the amended complaint highlighted the importance of security in the plaintiffs' decision to use Yahoo. 'Plaintiffs' allegations are sufficient to show that they would have behaved differently had defendants disclosed the security weaknesses of the Yahoo Mail System," Koh wrote. She also said the plaintiffs could try to show that liability limits in Yahoo's terms of service were "unconscionable," given the allegations that Yahoo knew its security was deficient but did little.
The security community is also steadily addressing the linchpin to all the assaults: the vulnerable memcached servers. About 100,000 of these online storage systems were publicly exposed over a week ago. But the server owners have since patched or firewalled about 60,000 of them, Radware security researcher Daniel Smith said. That leaves 40,000 servers open to exploitation. Smith points to how the coding behind the attack technique has started to circulate online through free tools and scripts.
Meanwhile, Slashdot reader darthcamaro shares an article about "the so-call 'kill switch'" that some vendors have been debating: "The 'kill switch' was immediately obvious to everyone who worked on mitigating this DDoS attack," John Graham-Cumming, CTO of CloudFlare said. "We chose not to use or test this method because it would be unethical and likely illegal since it alters the state of a remote machine without authorization."
According to researchers, SgxSpectre works because of specific code patterns in software libraries that allow developers to implement SGX support into their apps. Vulnerable SGX development kits include the Intel SGX SDK, Rust-SGX, and Graphene-SGX. Academics say an attacker can leverage the repetitive code execution patterns that these SDKs introduce in SGX enclaves and watch for small variations of cache size. This allows for side-channel attacks that allow a threat actor to infer and slowly recover data from secure enclaves.
Intel's recent Spectre patches don't necessarily help, as an attacker can work around these fixes. Intel says an update for the Intel SGX SDK that adds SgxSpectre mitigations will be released on March 16. Apps that implement Google's Retpoline anti-Spectre coding techniques are safe, researchers say.
Phishing attacks started in early January, but the Binance team says it detected evidence that operations ramped up around February 22, when the campaign reached its peak. Binance tracked down this phishing campaign because the phishing pages would immediately redirect phished users to the real Binance login page. This left a forensic trail in referral logs that Binance developers detected. After getting access to several accounts, instead of using the login credentials to empty out wallets, hackers created "trading API keys" for each account. With the API keys in hand, hackers sprung their main attack yesterday. Crooks used the API keys to automate transactions that sold Bitcoin held in compromised Binance accounts and automatically bought Viacoin from 31 other Binance accounts that hackers created beforehand, and where they deposited Viacoin, ready to be bought. But hackers didn't know one thing -- Binance's secret weapon -- an internal risk management system that detected the abnormal amount of Bitcoin-Viacoin sale orders within the span of two minutes and blocked all transactions on the platform. Hackers tried to cash out the 31 Binance accounts, but by that point, Binance had blocked all withdrawals.
This is what the Indiana State Police bought, judging by a purchase order obtained by Motherboard. The document, dated February 21, is for one GrayKey unit costing $500, and a "GrayKey annual license -- online -- 300 uses," for $14,500. The order, and an accompanying request for quotation, indicate the unlocking service was intended for Indiana State Police's cybercrime department. A quotation document emblazoned with GrayShift's logo shows the company gave Indiana State Police a $500 dollar discount for their first year of the service. Importantly, according to the marketing material cited by Forbes, GrayKey can unlock iPhones running modern versions of Apple's mobile operating system, such as iOS 10 and 11, as well as the most up to date Apple hardware, like the iPhone 8 and X.
That's according to new research from the University of Toronto's Citizen Lab, which has examined misuse of similar equipment from other companies in the past. The researchers say it's likely that Sandvine devices are not only being used to block the websites of news, political and human rights organizations, but are also surreptitiously redirecting users toward spyware and unwanted ads. Using network-filtering devices to sneak spyware onto targets' computers "has long been the stuff of legends" according to the report -- a practice previously documented in leaked NSA documents and spyware company brochures, the researchers say, but never before publicly observed. Citizen Lab notes that targeted users in Turkey and Syria who attempted to download Windows applications from official vendor websites including Avast Antivirus, CCleaner, Opera, and 7-Zip were silently redirected to malicious versions by way of injected HTTP redirects. It adds: This redirection was possible because official websites for these programs, even though they might have supported HTTPS, directed users to non-HTTPS downloads by default. Additionally, targeted users in Turkey and Syria who downloaded a wide range of applications from CBS Interactive's Download.com (a platform featured by CNET to download software) were instead redirected to versions containing spyware. Download.com does not appear to support HTTPS despite purporting to offer "secure download" links.
