美國. 藥物執行人員用途鑰匙日誌記錄器 旁路 PGP和Hushmail加密：

一個代理與DEA說服一位聯邦法官批准他偷偷地走入Escondido、加利福尼亞、辦公室認為的是前面為製造藥物MDMA或者銷魂。 DEA被獲得的許可複製硬盤』內容和注射擊鍵日誌記錄器入計算機。因為嫌疑犯使用PGP和被加密的網電子郵件服務Hushmail.com，那根據禁藥取締機構事務官格雷戈Coffey是必要的。 Coffey斷言DEA需要「實時和意味深長的通入」 「監測擊鍵」為PGP和Hushmail passphrases。

并且FBI使用的spyware 對顯示器 某人被懷疑做炸彈威脅：

In an affidavit seeking a search warrant to use the software, filed last month in U.S. District Court in the Western District of Washington, FBI agent Norman Sanders describes the software as a “computer and internet protocol address verifier,” or CIPAV.The full capabilities of the FBI’s “computer and internet protocol address verifier” are closely guarded secrets, but here’s some of the data the malware collects from a computer immediately after infiltrating it, according to a bureau affidavit acquired by Wired News.

• IP address
• MAC address of ethernet cards
• A list of open TCP and UDP ports
• A list of running programs
• The operating system type, version and serial number
• The default internet browser and version
• The registered user of the operating system, and registered company name, if any
• The current logged-in user name
• The last visited URL

Once that data is gathered, the CIPAV begins secretly monitoring the computer’s internet use, logging every IP address to which the machine connects.

All that information is sent over the internet to an FBI computer in Virginia, likely located at the FBI’s technical laboratory in Quantico.

Sanders wrote that the spyware program gathers a wide range of information, including the computer’s IP address; MAC address; open ports; a list of running programs; the operating system type, version and serial number; preferred internet browser and version; the computer’s registered owner and registered company name; the current logged-in user name and the last-visited URL.

The CIPAV then settles into a silent “pen register” mode, in which it lurks on the target computer and monitors its internet use, logging the IP address of every computer to which the machine connects for up to 60 days.

I’ve been saying this for a while: the easiest way to get at someone’s communications is not by intercepting it in transit, but by accessing it on the sender’s or recipient’s computers.

I should add that the police got a warrant in both cases. This is not a story about abuse of police power or surveillance without a warrant. This is a story about how the police conducts electronic surveillance, and how they bypass security technologies.
