駭客年會 2015 能量分析攻擊 (Power Analysis Attacks)
大綱:1998年 Paul Kocher 等人提出差分能量攻擊 (Differential Power Analysis, DPA),開創了新的密碼分析領域,這類攻擊統稱為旁通道攻擊 (Side Channel Attacks, SCA)。攻擊者測量密碼裝置運作時洩漏的資訊,如運作時間、能量消耗 (power consumption)、電磁場變化、甚至裝置發出的聲波等參數,再透過分析收集的資訊獲得密鑰...
OSSLab 心得
SMARTCard破解我們實驗室會偏向於 iso 7816仿真,其實這是很老又很普遍hacking技術,用網路封送iso 協議...這個常用於付費衛星收視破解.一張正版衛星卡 ,大家共用這張正版卡的iso 7816 協議(嗯 衛星解密是單向通訊) 這硬體叫CV12很便宜也很多..缺點是 母卡當然要接在讀卡機上再做iso 7816 replay.
現行非網路類 IOT 的漏洞分析,大部份還有留TTL,JTAG debug port 做reversing,ROM 用SPI,NAND(EMMC) dump 這樣會比能量分析省事點
有人問我能量分析是否萬用,第一個問題是要做訊號取樣,第二主要用於已經沒有半個 debug port, 再來是做keystroke 分析也不錯.
像這個範例電子安全保險箱沒半個debug port外露,但是電源做在外露..(要不然沒電了就打不開了)有EE工程師用示波器做電子保險箱的能量分析,下面是非常棒的step by step 教學影片(雖然能量分析法失敗 , 因為只能抓出四位密碼,因為try error 有限制 ,但流程值得一學, 最後成功的方法是跟電影沒二樣 ,用電鑽鑽旁邊 ,電源進入保險箱電磁閥接點)

Detroit: Become Human is the latest interactive narrative game from Quantic Dream, makers of Heavy Rain and Beyond: Two Souls.
Detroit: Become Human is an adventure game played from a third-person view,
which is subject to a set and controllable perspective.
There are multiple playable characters who can die as the story continues without them
as a result, there is no "game over" message following a character's death.
The right analogue stick on the DualShock controller is used to interact with objects and observe one's surroundings, the left is for movement, and R2 scans an environment for possible actions; the motion controls and touchpad are also employed. Via quick time events and dialogue decisions,
the story will branch out depending on which choices are made.
These can be viewed in a flowchart during and immediately after a given chapter;[16] the player can rewind to certain points in the story to reshape decisions in the event of regret.
Certain scenes feature countdowns, which force the player to think and act quickly.
Levels abound with magazines for players to read.
The playable characters are:
* Connor, a police investigator android tasked with hunting down androids that have deviated from their programmed behaviours.
*
* Kara, a housekeeper android who develops artificial consciousness and becomes responsible for a young girl's safety.
*
* Markus, a caretaker android who, after gaining consciousness, takes it upon himself to free others like him from bondage.
*
Obtaining clues by highlighting and analysing the environment with augmented vision allows Connor to reconstruct and replay events that occurred before.
The more information Connor collects within an allotted time,
the greater the chance of success in deciding a course of action.
Markus has the power to grant androids free will and calculate the outcomes of certain acts.
Caretaker android Markus and his owner return home and alert the police of a suspected burglary. In confronting the perpetrator, Markus bypasses his programming, thereby becoming a deviant android with full autonomy, leading the police to shoot him at arrival.
Markus awakes in a landfill of broken androids and, after escaping, discovers Jericho,
a wrecked ship and safe haven for deviants. There, Markus rallies the others to fight for their rights.
They perform several acts of civil disobedience, which catches the public's attention and gets more androids to join.
This culminates with the FBI attacking Jericho.
If he survives, Markus and the others set up a final march, resulting in either all of the deviants being killed or the president opening peace talks.
Police investigator android Connor is sent by the CyberLife corporation to assist Lieutenant Hank Anderson, an alcoholic who hates androids.
In the course of their investigation into an outbreak of deviants,
they either bond or fall apart,
potentially resulting in Hank committing suicide.
During his hunt for Markus' group, Connor starts to doubt himself, though he can stay firm in his beliefs.
He eventually locates Jericho,
where he can become a deviant himself.
If he defects, Connor infiltrates CyberLife Tower and converts everyone there into deviants. If not, he attempts to snipe Markus during the final protest, but is stopped by a SWAT team or Hank. In the end, if peace is achieved, Connor can choose whether or not to shoot Markus during a speech.
Kara, a housekeeper android for Todd Williams and his daughter Alice,escapes with her after he attacks them and leaves Kara a deviant.
The two travel across Detroit, intending to make it to Canada, which has no specific laws involving androids and where they will be safe. Kara and Alice befriend another android named Luther along the way, who joins them on their journey.
They seek the aid of an android sympathiser, who points them to Jericho to obtain passports.
They get caught up in the attack there, which may result in Luther, Kara, and Alice's deaths. Kara also learns that Alice is in fact an android, replacing the daughter taken away by Todd's wife.
They can make it to Canada by bus or boat, survive a recycling centre, or in either case die trying.
