Analysis: Israel’s misjudgment of Hamas caused the October 7 intelligence failure
November 10, 2023 6 Comments
SINCE OCTOBER 7, WHEN Hamas launched its surprise attack on Israel, many more details about the intelligence failure have emerged. It appears that Israeli intelligence officials have warned for years about military exercises held by Hamas in the Gaza Strip, which have included practice raids on cities deep inside Israel. However, the Israel Military Intelligence (IMI) did not heed to the warnings, because it considered Hamas operationally incapable of carrying out such raids. Instead, the IMI estimated that the Hamas leadership aimed to arrive at a settlement with Israel. That seems like the result of a highly successful disinformation operation, which added significantly to the effectiveness of the sudden attack on Israel on October 7.
It now appears that several months after the Israel Defense Forces (IDF) Operation Guardian of the Walls, which targeted Hamas in the Gaza Strip in May of 2021, Hamas began to train for a large-scale operation against Israel. However, the IMI estimated that Hamas was not capable of attacking a
large number of settlements simultaneously. It also believed that such an operation would go against the spirit of Hamas leadership’s spirit intention to settle with Israel.
As early as 2022, the IMI had analyzed videos of Hamas’ military exercises, which Hamas itself had made available on social media networks. Meanwhile, the intelligence information that emerged from the Gaza Strip showed that the professionalization of Hamas’ military arm, the Izz ad-Din al-Qassam Brigades, was improving. However, IMI officials rejected the need to build an operative response to the mass-attack scenario that these exercises pointed to, because they saw them simply as exercises.
Israeli intelligence also analyzed the communications discourse between the commanders of Hamas, which it had acquired through intercepts. It purportedly indicated that Hamas intended to carry out raids on Israeli communities located near the fence between Israel and Gaza, but also on targets located deeper inside Israel. The communications discourse also indicated that such attacks could occur, not only using tunnels, but with incursions above ground and even through aerial methods.
One of the methods that Hamas trained on, and one that was known to Israeli intelligence, focused on disabling the highly sophisticated observation posts, sensors and remote-controlled machine guns, which Israel has installed along the border fence with the Gaza Strip. The purpose of these exercises was to enable an attack on the fence and overtake it these sophisticated tools with Hamas operatives, thus effectively blinding the Israeli forces. However, Israeli authorities made no effort to prepare for such a scenario by protecting these installations.
The broad picture that is emerging raises serious questions about why the IDF did not take a reasonable course of action against Hamas’ operational plan —and why it failed to do so despite being aware of the intensity of the Hamas exercises, and despite being aware of the group’s stated intentions. 
Indeed, a preventive course of action should have been in place even in the absence of specific intelligence warnings —if only to enable the IDF to repel a surprise attack by Hamas. There was no need to estimate what Hamas would do in order to prepare for a surprise attack.
Yet it is now patently obvious that there was ample intelligence about Hamas’ intentions. The latter were both apparent and known. Even without the wisdom of hindsight, it is clear there was enough intelligence to enable Israel to act in a timely manner against Hamas’ plan. Yet Israel severely misjudged Hamas’ intentions. In retrospect, it appears that ample intelligence about Hamas’ intentions had been gathered, that the IMI and Shin Bet were severely underprepared for a surprise attack, that the precise details of Hamas’ attack were missed, and that Hamas’ intentions were misjudged. These are the reasons why Israel was caught unprepared and suffered a catastrophic surprise on October 7.

THE COMPARISON BETWEEN THE October 2023 attack on Israel and the Yom Kippur War is reasonable. We still have an obscured perspective on what happened on October 7.

THE HAMAS-LED OPERATION al-Aqsa Flood, which began on October 7, marked the first large-scale conflict within the borders of Israel since the 1948 Arab-Israeli War. However, unlike the coalition of Arab armies it faced in 1948, Israel now confronts an alliance of sub-state groups. Led by Hamas’ military wing, the al-Qassam Brigades, this alliance includes the Syrian- and Iranian-backed Palestinian Islamic Jihad and a number of secular groups, such as the Fatah-aligned al-Aqsa Martyrs’ Brigades, the Popular Front for the Liberation of Palestine (PFLP) and the Democratic Front for the Liberation of Palestine (DFLP).
IN THE EARLY HOURS of June 23, PMC Wagner leader Yevgeny Prigozhin declared the launch of an armed campaign against the Ministry of Defense of the Russian Federation. Within hours, several thousand soldiers belonging to Wagner, one of the world’s largest private military companies, had abandoned their positions in eastern Ukraine and were en route to Moscow. Their mission, according to Prigozhin, was to arrest Minister of Defense Sergei Shoigu and Chief of the General Staff Valery Gerasimov, and try them for mismanagement and corruption.
Wagner leader has repeatedly expressed his dismay at being viewed as an outsider by the Ministry of Defense, which it views as an elitist and incompetent bureaucracy. His experience in Ukraine, where Wagner’s forces faced stiff resistance from the local population and the Ukrainian military alike, added fuel to his rage against a host of Russian defense officials. Prigozhin has been voicing his denunciations of the way these officials have managed the war since March of 2022, just two weeks into the invasion of Ukraine.
THE 49-PAGE GRAND JURY indictment, filed last week in Florida by the United States Department of Justice, contains 37 criminal charges against former president Donald Trump. The charges can be summarized into a two-fold accusation: Trump is alleged to have stolen more than 300 classified documents upon leaving the White House in January 2021. Moreover, he allegedly schemed with a group of advisors and aides in order to obstruct efforts by the government to retrieve the stolen documents. Both accusations are spelled out in stark detail in

FEMALE TARGETS OF CONSPIRACY theories propagated by QAnon adherents face up to 10 times more online harassment and abuse than male targets, a behavioral study of pro-QAnon online users has found. QAnon refers to an American-rooted conspiracy theory that views former United States President Donald Trump as a central figure in a behind-the-scenes battle against a sinister cabal of enemies, known as the “deep state”. According to QAnon adherents, “deep state” elites (politicians, entertainment figures and other celebrities) consist of Satan-worshiping cannibals who traffic children for sex. QAnon adherents also believe that these elites will be routed during “The Storm”, a final reckoning between Trump and the “deep state”, which will result in the arrest and physical extermination of all elites.
IT IS DIFFICULT TO argue against the widely shared view that clandestine human intelligence (HUMINT) is replete with ethical dilemmas. These are inherent in the process of gathering intelligence via the use of human sources or covert agents. Yet it is possible —indeed desirable— for intelligence agencies to implement well-regulated ethical approaches to clandestine HUMINT, according to Dr. Stephan Lau, a junior professor of psychology and member of the Faculty of Intelligence at the Federal University of Administrative Sciences in Berlin, Germany.

The OSINT factor in Hamas’ operational success and Israel’s intelligence failure
December 5, 2023 by intelNews 1 Comment
It is also possible that some of the intelligence came from human intelligence (HUMINT) sources, largely through Gazan workers who were employed in Israel. Moreover, Hamas had access to constant Israeli media broadcasts, which supplied them with invaluable intelligence on the border communities and adjacent military facilities, as well as on communities that were located further to the north and east. Although the Israeli state exercises censorship in the
interests of national security, the public’s ‘right to know’ purview is substantial. Thus, significant amounts of information are available online.
In assessing the behavior of Hamas in recent years, one can observe that it did not act as a terrorist group for quite some time. Rather, it operated as a government organization, while monitoring its enemy and waiting patiently for an opportune moment to attack. Simultaneously, Hamas utilized disinformation tools to conceal its attack plans. It trained its fighters within commando units that employed information effectively and relied on actionable intelligence, rather than chance. This can be observed from interrogations of Hamas members who were detained by Israeli authorities after October 7. In one example, Hamas used detailed maps of Israeli communities near the Gaza border, which are available on Google Earth, to plan its attacks of October 7. Printouts of these maps were found among the belongings of Hamas assailants that were killed during the attacks.
Some in Israel are now advocating for increased protection of OSINT, particularly for Israeli sites related to security, including civilian first-response units, defense systems guarding settlements, and civil technological assets. However, implementing such measures within the current framework of Israel’s open society seems challenging. Despite the known importance of OSINT to Hamas and its potential risk to Israel’s security, significant changes in this regard may not occur, as they could impact the country’s democratic values. However, it is still possible to improve the quality of security censorship regarding sensitive civilian information that can be used by adversaries. Such moves would include protecting databases, limiting information relating to the addresses of senior officials, or putting in place stricter policies on the movement of Gazan workers in Israel.
Contrary to Hamas’, Israel’s OSINT systems underperformed in the run-up to the October 7 attacks. That was so especially after the central OSINT unit of
the Israeli Military Intelligence was dissolved, for reasons that remain to be investigated. CNN was among many news outlets that have revealed how Hamas advertised its military drills on social media, but somehow Israeli intelligence failed to pay attention to them.
When Hamas openly declared its intention to attack communities near the Gaza border, and trained its units for that purpose, the Israeli intelligence community, including the IMI and the Israel Security Agency (ISA), underestimated its real attack capabilities based on OSINT materials. This miscalculation stemmed from incorrectly assessing Hamas’s capabilities and overestimating the Israel Defense Forces’ ability to swiftly respond and prevent the attack on civil and military targets. Unfortunately, this assessment proved to be a significant mistake.
The effective use of OSINT lies at the heart of Hamas’ operational plan to attack simultaneously several Israeli targets and to cause extensive damage. It appears that Hamas was able to utilize the OSINT factor to its maximum extent, thus adding significant value to the success of the attack.
