Persistent Dataonly Malware: Function Hooks without Code
"... Abstract—As protection mechanisms become increasingly advanced, so too does the malware that seeks to circumvent them. Protection mechanisms such as secure boot, stack protection, heap protection, W X, and address space layout randomization have raised the bar for system security. In turn, attack m ..."

presented above, however it has had, until now, one limitation. Due to the fact that it introduces no code, it is very difficult to achieve any sort of persistence. Placing a function hook is straightforward, but where should this hook point to if the malware introduces no code? There are many challenges
HookScout: Proactive BinaryCentric Hook Detection
, 2010
"... In order to obtain and maintain control, kernel malware usually makes persistent control flow modifications (i.e., installing hooks). To avoid detection, malware developers have started to target function pointers in kernel data structures, especially those dynamically allocated from heaps and memor ..."

Hook length formulas for trees by . . .
, 2009
"... Recently Han obtained a general formula for the weight function corresponding to the expansion of a series in terms of hook lengths of binary trees. In this paper, we present weight function formulas for kary trees, plane trees, plane forests, labeled trees and forests. We also find appropriate gen ..."

HOOK FORMULAS FOR SKEW SHAPES
"... Abstract. The celebrated hooklength formula gives a product formula for the number of standard Young tableaux of a straight shape. In 2014, Naruse announced a more general formula for the number of standard Young tableaux of skew shapes as a positive sum over excited diagrams of products of hookle ..."

Getting the Masses Hooked on Haskell
"... When considering the past or the future, dear apprentice, be mindful of the present. If, while considering the past, you become caught in the past, lost in the past, or enslaved by the past, then you have forgotten yourself in the present. If, while considering the future, you become caught in the f ..."

principles from functional programming, in particular monads and comprehensions. By viewing data as monads and formulating queries as comprehensions, it becomes possible to unify the three data models and their corresponding programming languages instead of considering each as a separate special case
Hooklengths and Pairs of Compositions
, 2004
"... Abstract. The nonsymmetric Jack polynomials are defined to be the simultaneous eigenfunctions of a parametrized commuting set of firstorder differentialdifference operators. These polynomials form a basis for the homogeneous polynomials and they are labeled by compositions, just like the monomials. ..."

. The coefficients of the polynomials when expanded in the standard monomial basis are rational functions of the parameter. The poles are determined by certain hooklength products. Another way of locating the poles depends on possible degeneracies of the eigenvalues under the defining set of operators, when
Quasisymmetric (k, l)hook Schur functions
"... Abstract. We introduce a quasisymmetric generalization of Berele and Regev’s hook Schur functions and prove that these new quasisymmetric hook Schur functions decompose the hook Schur functions in a natural way. In this paper we examine the combinatorics of the quasisymmetric hook Schur functions, p ..."

Expected lengths and distribution functions for Young diagrams in the hook
, 2005
"... We consider β–Plancherel measures [5] on subsets of partitions – and their asymptotics. These subsets are the Young diagrams contained in a (k, ℓ)–hook, and we calculate the asymptotics of the expected shape of these diagrams, relative to such measures. We also calculate the asymptotics of the distr ..."

of the distribution function of the lengths of the rows and the columns for these diagrams. This might be considered as the restriction to the (k, ℓ)–hook of the fundamental work of Baik, Deift and Johansson [3]. The above asymptotics are given here by ratios of certain Selbergtype multi–integrals. 1
Schur Function Identities and Hook Length Posets
"... Abstract. In this paper we find new classes of posets which generalize the dcomplete posets. In fact the dcomplete posets are classified into 15 irreducible classes in the paper “Dynkin diagram classification of λminuscule Bruhat lattices and of dcomplete posets ” (J. Algebraic Combin. 9 (1999), ..."

The Kronecker product of Schur functions indexed by tworow shapes or hook shapes
 J. Algebraic Combin

The Kronecker product of two Schur functions sµ and sν, denoted by sµ ∗sν, is the Frobenius characteristic of the tensor product of the irreducible representations of the symmetric group corresponding to the partitions µ and ν., and corresponds to the The coefficient of sλ in this product ..."

Remmel [9, 10] and Remmel and Whitehead [11] derived some closed formulas for the Kronecker product of Schur functions indexed by tworow shapes or hook shapes using a different approach. We believe that the approach of this paper is more natural. The formulas obtained
